1 RATIONALEMathematics is an integral part of a general education. It enhances both an understanding of the world and the quality of participation in a rapidly changing society.

Mathematics has been central to nearly all major scientific and technological advances. Many of the developments and decisions made in industry and commerce, in the provision of social and community services, and in government policy and planning, rely on the use of mathematics. Consequently, the range of career opportunities requiring and/or benefiting from an advanced level of mathematical expertise is rapidly expanding. For example, mathematics is increasingly important in health and life sciences, biotechnology, environmental science, economics, and business while remaining crucial in such fields as the physical sciences, engineering, accounting, computer science and the information technology areas.

Mathematics C aims to provide opportunities for students to participate more fully in life-long learning, to develop their mathematical potential, and to build upon and extend their mathematics. It is extremely valuable for students interested in mathematics. Students studying Mathematics C in addition to Mathematics B gain broader and deeper mathematical experiences that are very impor-tant for future studies in areas such as the physical sciences and engineering. They are also signifi-cantly advantaged in a wide range of areas such as finance, economics, accounting, information technology and all sciences. Mathematics C provides the opportunity for student development of: knowledge, procedures and skills in mathematics mathematical modelling and problem-solving strategies the capacity to justify and communicate in a variety of forms.

Mathematics students should recognise the dynamic nature of mathematics through the subject matter of Mathematics C which includes the concepts and application of matrices, vectors, complex numbers, structures and patterns, and the practical power of calculus. In the optional topics, students may also gain knowledge and skills in topics such as conics, dynamics, statistics, numerical methods, exponential and logarithmic functions, number theory, and recent developments in mathematics.

Mathematics has provided a basis for the development of technology. In recent times, the uses of mathematics have developed substantially in response to changes in technology. The more technology is developed, the greater is the level of mathematical skill required. Students must be given the opportunity to appreciate and experience the power which has been given to mathematics by this technology. Such technology should be used to help students understand mathematical concepts, allowing them to “see” relationships and graphical displays, to search for patterns and recurrence in mathematical situations, as well as to assist in the exploration and investigation of purely mathematical, real and life-like situations.

The intent of Mathematics C is to encourage students to develop positive attitudes towards mathematics by an approach involving exploration, investigation, problem solving and application in a variety of contexts. Of importance is the development of student thinking skills, as well as student recognition and use of mathematical structures and patterns. Students will be encouraged to model mathematically, to work systematically and logically, to conjecture and reflect, to prove and justify, and to communicate with and about mathematics.

The subject is designed to raise the level of competence and confidence in using mathematics, through aspects such as analysis, proof and justification, rigour, mathematical modelling and problem solving. Such activities will equip students well in more general situations, in the appreciation of the power and diversity of mathematics, and provide a very strong basis for a wide range of further mathematics studies.

Mathematics C provides opportunities for the development of the key competencies in situations that arise naturally from the general objectives and learning experiences of the subject. The seven key competencies are: collecting, analysing and organising information; communicating ideas and information; planning and organising activities; working with others and in teams; using mathematical ideas and techniques; solving problems; using technology. (Refer to Integrating the Key Competencies into the Assessment and Reporting of Student Achievement in Senior Secondary Schools in Queensland, published by QBSSSS in 1997.)

The Rockhampton Grammar School is a non denominational, coeducational, day and boarding school with a total school population of approximately 1000 students from Years 1 to 12. The school has a boarding population in excess of 400. The catchment area is the rural and mining areas to the west and north west of Rockhampton.

The school tends to be an academic school and offers Mathematics A, Mathematics B and Mathematics C. The S.A.S. Mathematics Courses are not offered by The Rockhampton Grammar School. Almost all students completing Mathematics B proceed to tertiary studies. Consequently the Mathematics C course offered by the school is designed to satisfy this outcome. Technologically, the school is well resourced with extensive on line facilities available to all students. In addition all students are required to own a Casio 9850 calculator.

2 GLOBAL AIMSHaving completed the course of study, students of Mathematics C should: be able to recognise when problems are suitable for mathematical analysis and solution, and

be able to attempt such analysis or solution with confidence be able to visualise and represent spatial relationships in both two and three dimensions have experienced diverse applications of mathematics have positive attitudes to the learning and practice of mathematics comprehend mathematical information which is presented in a variety of forms communicate mathematical information in a variety of forms be able to benefit from the availability of a wide range of technologies be able to choose and use mathematical instruments appropriately be able to recognise functional relationships and dependent applications have significantly broadened their mathematical knowledge and skills have increased their understanding of mathematics and its structure through the depth and

breadth of their study.

3 GENERAL OBJECTIVES

3.1 Introduction

The general objectives of this course are organised into four categories: Knowledge and procedures

Mathematics C Work Program page - 3 My School

Page 6: 1 - Tripod.comrex.boggs.tripod.com/docs/workprog_mac.doc · Web view9. investigate how to construct the elliptical hole required to be cut out of a sloping roof to fit a vertical

Modelling and problem solving Communication and justification Affective.

3.2 Contexts

The categories of Knowledge and procedures, Modelling and problem solving, and Communication and justification incorporate contexts of application, technology, initiative and complexity. Each of the contexts has a continuum for the particular aspect of mathematics it represents. Mathematics in a course of study developed from this syllabus must be taught, learned and assessed using a variety of contexts over the two years. It is expected that all students are provided with the opportunity to experience mathematics along the continuum within each of the contexts outlined below.

ApplicationStudents must have the opportunity to recognise the usefulness of mathematics through its application, and the beauty and power of mathematics that comes from the capacity to abstract and generalise. Thus students’ learning experiences and assessment programs must include mathematical tasks that demonstrate a balance across the range from life-related through to pure abstraction.

TechnologyA range of technological tools must be used in the learning and assessment experiences offered in this course. This ranges from pen and paper, measuring instruments and tables through to higher technologies such as graphing calculators and computers. The minimum level of higher technology appropriate for the teaching of this course is a graphing calculator.

InitiativeLearning experiences and the corresponding assessment must provide students with the opportunity to demonstrate their capability when dealing with tasks that range from routine and well rehearsed through to those that require demonstration of insight and creativity.

ComplexityStudents must be provided with the opportunity to work on simple, single-step tasks through to tasks that are complex in nature. Complexity may derive from either the nature of the concepts involved or from the number of ideas or techniques that must be sequenced in order to produce an appropriate conclusion.

3.3 Objectives

The general objectives for each of the categories in section 3.1 are detailed below. These general objectives incorporate several key competencies. The first three categories of objectives, Knowledge and procedures, Modelling and problem solving, and Communication and justification, are linked to the exit criteria in section 7.3.

3.3.1 Knowledge and Procedures

The objectives of this category involve the recall and use of results and procedures within the contexts of application, technology, initiative and complexity. (see section 3.2)

Mathematics C Work Program page - 4 My School

Page 7: 1 - Tripod.comrex.boggs.tripod.com/docs/workprog_mac.doc · Web view9. investigate how to construct the elliptical hole required to be cut out of a sloping roof to fit a vertical

By the conclusion of the course, students should be able to: recall definitions and results access and apply rules and techniques demonstrate number and spatial sense demonstrate algebraic facility demonstrate an ability to select and use appropriate technology such as calculators,

measuring instruments, geometrical drawing instruments and tables demonstrate an ability to use graphing calculators and/or computers with selected software

in working mathematically select and use appropriate mathematical procedures work accurately and manipulate formulae recognise some tasks may be broken up into smaller components transfer and apply mathematical procedures to similar situations understand the nature of proof.

3.3.2 Modelling and Problem Solving

The objectives of this category involve the use of mathematics in which the students will model mathematical situations and constructs, solve problems and investigate situations mathematically within the contexts of application, technology, initiative and complexity. (see section 3.2)

By the conclusion of the course, students should be able to demonstrate the category of modelling and problem solving through:

Modelling understanding that a mathematical model is a mathematical representation of a situation identifying the assumptions and variables of a simple mathematical model of a situation forming a mathematical model of a life-related situation deriving results from consideration of the mathematical model chosen for the particular

situation interpreting results from the mathematical model in terms of the given situation exploring the strengths and limitations of a mathematical model and modifying the model as

appropriate.

Problem solving interpreting, clarifying and analysing a problem using a range of problem solving strategies such as estimating, identifying patterns, guessing

and checking, working backwards, using diagrams, considering similar problems and organising data

understanding that there may be more than one way to solve a problem selecting appropriate mathematical procedures required to solve a problem developing a solution consistent with the problem developing procedures in problem solving.

Investigation identifying and/or posing a problem exploring the problem and from emerging patterns creating conjectures or theories reflecting on conjectures or theories making modifications if needed selecting and using problem-solving strategies to test and validate any conjectures or

theories extending and generalising from problems developing strategies and procedures in investigations.

3.3.3 Communication and Justification

The objectives of this category involve presentation, communication (both mathematical and everyday language), logical arguments, interpretation and justification of mathematics within the contexts of application, technology, initiative and complexity. (see section 3.2)

CommunicationBy the conclusion of the course, students should be able to demonstrate communication through: organising and presenting information communicating ideas, information and results appropriately using mathematical terms and symbols accurately and appropriately using accepted spelling, punctuation and grammar in written communication understanding material presented in a variety of forms such as oral, written, symbolic,

pictorial and graphical translating material from one form to another when appropriate presenting material for different audiences, in a variety of forms such as oral, written,

symbolic, pictorial and graphical recognising necessary distinctions in the meanings of words and phrases according to

whether they are used in a mathematical or non-mathematical situation.

JustificationBy the conclusion of this course, the student should be able to demonstrate justification through: developing logical arguments expressed in everyday language, mathematical language or a

combination of both, as required, to support conclusions, results and/or propositions evaluating the validity of arguments designed to convince others of the truth of propositions justifying procedures used recognising when and why derived results to a given problem are clearly improbable or

unreasonable recognising that one counter example is sufficient to disprove a generalisation recognising the effect of assumptions on the conclusions that can be reached deciding whether it is valid to use a general result in a specific case recognising that a proof may require more than verification of a number of instances using supporting arguments, when appropriate, to justify results obtained by calculator or

computer using different methods of proof.

3.3.4 Affective

Affective objectives refer to the attitudes, values and feelings which this subject aims at developing in students. Affective objectives are not assessed for the award of exit levels of achievement.

By the conclusion of the course, students should appreciate the: diverse applications of mathematics precise language and structure of mathematics uncertain nature of the world, and be able to use mathematics to assist in making informed

decisions in life-related situations diverse and evolutionary nature of mathematics through an understanding of its history wide range of mathematics-based vocations contribution of mathematics to human culture and progress power and beauty of mathematics.

4 COURSE ORGANISATIONThis school will continue to strive for educational equity by providing a curriculum which in subject matter, language, methodology, learning experiences and assessment instruments meets the educational needs and entitlements of all students. This program reflects school policy on equity in education (see Appendix 3), and teachers should implement the course with consideration of these issues.

4.1 Course Description

The course is intended to offer to students an integrated, spiralling curriculum. Although all topics are not covered in every semester, the concepts dealt with will be drawn upon in subsequent topics.

In allocating time to units, consideration has been given to the maintenance of basic skills and mathematical techniques as appropriate. The revision of basic mathematics should be done when needed and the maintenance of mathematical techniques should be ongoing throughout the course.

At the time of writing, Mathematics C has allocated 6 periods or about 230 minutes per week.

A brief summary of the integrated sequence of topics and a more detailed sequence are provided in the following pages. A summary of the focus statements for each topic, which should be referred to each time a topic is studied, is provided as Appendix 2. This sequence has been designed to:

allow for the gradual development of the objectives over time ensure that pre-requisite material from Mathematics C has been covered at appropriate times allow for the use of technology wherever possible, particularly graphics calculators and

computer software.

The School offers the two optional topics, Conics and Dynamics.

Although the sequence on the following pages does not show explicitly the integration of the syllabus topics, due to the difficulty of doing this in a limited space, teachers will be expected to integrate the topics wherever possible to ensure that students do not see mathematics as a series of discrete topics. Students will be encouraged to select from all their skills when problem solving.

While the sequence provided shows the order in which topics will generally be covered, the school reserves the right to modify this with specific cohorts to suit the specific conditions that year. The same work would, however, be covered for inclusion at Monitoring and Verification.

Focus Statement

When planning units of work, the following detailed sequence should be considered in conjunction with Appendix II which contains the focus statements, subject matter and learning experiences linked to the subject matter for each topic.

The topic sequence for Mathematics B and Mathematics C have been developed together, to ensure that significant pre-requisite material is taught in Mathematics B before being required in Mathem-atics C.

4.4 Technology

Throughout the course of study, higher technologies such as graphics calculators and appropriate computer software will be used to reduce computational and algebraic drudgery and to aid in invest-igation and development of concepts. Such technology will also be used in assessment tasks where appropriate.

4.5 Language Education

Language is the means by which meaning is constructed and shared and communication is effected. It is the central means by which teachers and students learn. Mathematics C requires students to use language in a variety of ways – mathematical, spoken, written, graphical, symbolic. The responsib-ility for developing and monitoring students’ abilities to use effectively the forms of language de-manded by this course rests with the teachers of mathematics. This responsibility includes develop-ing students’ abilities to: select and sequence information manage the conventions related to the forms of communication used in Mathematics C (such

as short responses, reports, multi-media presentations, seminars) use the specialised vocabulary and terminology related to Mathematics C use language conventions related to grammar, spelling, punctuation and layout.

The learning of language is a developmental process. When writing, reading, questioning, listening and talking about mathematics, teachers and students should use the specialised vocabulary related to Mathematics C. Students should be involved in learning experiences that require them to compre-hend and transform data in a variety of forms and, in so doing, use the appropriate language con-ventions. Some language forms may need to be explicitly taught if students are to operate with a high degree of confidence within mathematics.

Assessment instruments will use format and language that are familiar to students. They will be taught the appropriate language skills to interpret questions accurately and to develop coherent, logical and relevant responses. Attention to language education within Mathematics C should assist students to meet the language components of the exit criteria, especially the Communication and justification criterion.

55 LEARNING EXPERIENCES

Throughout the course, students will be exposed to a variety of learning experiences to help them achieve the general objectives. These learning experiences will also incorporate the contexts of application, technology, initiative and complexity. Some of these are shown below in general terms:

traditional methods of exposition, reinforcement, discussion investigations individual and group work requiring research, problem solving and modelling either as supervised

school activities or as unsupervised out-of-class activities computer software and graphics calculators integrated into the course where appropriate.

Included in Appendix 2 are the suggested learning experiences from the syllabus linked to the subject matter. This information, combined with the focus statements should be used when designing a specific learning program and to give a guide to the depth of treatment required.

Mathematics C Work Program page - 17 My School

Page 20: 1 - Tripod.comrex.boggs.tripod.com/docs/workprog_mac.doc · Web view9. investigate how to construct the elliptical hole required to be cut out of a sloping roof to fit a vertical

Included in Appendix 1 is a sample unit of work showing the range of learning experiences which might be included to develop the objectives of the course. While the actual learning experiences provided to students will vary from one topic to another and from one year to another, this school will provide a similar variety of learning experiences to ensure that all the objectives of the course are developed.

6 ASSESSMENT

Student achievement will be judged on the following three exit criteria: Knowledge and procedures Modelling and problem solving Communication and justification.

A system of continuous assessment is used by this school to gather data on student performance during the course. After each assessment instrument has been administered the students' results are recorded on an individual student profile.

This profiling of student performance allows both teachers and students to review student's performance and allows students to become aware of the criteria in which they need to improve.

Assessment instruments will be both formative and summative. Formative instruments will be administered in year 11. These instruments will be similar in style to those administered in year 12 to allow students to become familiar with different types of assessment. Year 12 instruments will provide the summative data for awarding exit levels of achievement for students who complete the course. Formative results will be referred to in the allocation of a level of achievement when a student exits before completion of the course and for awarding interim levels of achievement for reporting on student's progress and for Monitoring purposes at the end of year 11.

Students’ responses to at least one, and probably two, assessment tasks from semester IV will be included in the verification submission in October.

6.1 Assessment Techniques

Assessment techniques other than traditional written tests or examinations will be included in the assessment program at least twice each year.

A variety of assessment techniques will be used and might include those described below.

Extended modelling and problem-solving tasksThis form of assessment may require a response that involves mathematical language, graphs and diagrams, and could involve a significant amount of conventional English. It will typically be in written form, a combination of written and oral forms, or multimedia forms.

The activities leading to an extended modelling and problem-solving task could be done individually and/or in groups, and the extended modelling and problem-solving task could be prepared in class time and/or in students’ own time.

Page 21: 1 - Tripod.comrex.boggs.tripod.com/docs/workprog_mac.doc · Web view9. investigate how to construct the elliptical hole required to be cut out of a sloping roof to fit a vertical

Reports

A report is typically an extended response to a task such as: an experiment in which data is collected, analysed and modelled a mathematical investigation a field activity a project.

A report could comprise such forms as: a scientific report a proposal to a company or organisation a feasibility study.

The activities leading to a report could be done individually and/or in groups and the report could be prepared in class time and/or in students’ own time. A report will typically be in written form, or a combination of written and oral multimedia forms.

The report will generally include an introduction, analysis of results and data, conclusions drawn, justification, and, when necessary, a bibliography, references and appendices.

Supervised Tests

Supervised tests commonly include tasks requiring quantitative and/or qualitative responses. Supervised tests could include a variety of items such as: multiple-choice questions questions requiring a short response:

in mathematical language and symbols in conventional written English, ranging in length from a single word to a paragraph

questions requiring a response including graphs, tables, diagrams and data questions requiring an extended answer where the response includes:

mathematical language and symbols conventional written English, more than one paragraph in length a combination of the above.

The assessment instruments will reflect an appropriate emphasis according to time spent on a topic and the depth of treatment undertaken.

Conditions of Implementation

To ensure that the data gained from our assessment program is valid and reliable, we will use a variety of conditions of implementation which may include supervised tests, supervised open-book tests (Modelling and problem solving only), assignments done in class, assignments done at home, and group projects. When assignments are done entirely in the students' own time, mechanisms will be put in place to ensure ownership of the work presented. These mechanisms may include asking students to sign declarations of "ownership", acknowledging any help received or "random" oral questioning of students to check understanding of work presented. The importance of intellectual integrity and honesty will be stressed to students.

Page 22: 1 - Tripod.comrex.boggs.tripod.com/docs/workprog_mac.doc · Web view9. investigate how to construct the elliptical hole required to be cut out of a sloping roof to fit a vertical

Where written tests are indicated these will generally be of the type:

(a) A test assessing Knowledge and procedures and Communication and justification(b) A test of up to 4 questions assessing Modelling and problem solving and

Communication and justification (this may need to be split into 2 parts to allow for sufficient thinking time).

(c) A test consisting of a number of items where part (a) of the item assesses specific knowledge and procedures followed by a part (b) which is modelling or problem solving which employs specifically part (a).

In all written tests, sufficient time will be allocated to ensure satisfactory coverage of topics studied, and to allow students adequate time to demonstrate their proficiency, thus ensuring time is not a hidden criterion.

The specific conditions appropriate to each instrument will be provided to the panel at Monitoring and Verification.

6.2 Assessment Outline

This school will have a minimum of 4 assessment instruments each semester. At least two of these tasks will be tests and at least one will be a task which is not a traditional written test.

All instruments will assess Communication and justification and all three criteria will be assessed on written tests (see note above). In any one semester, each criterion will be assessed on at least two instruments. The sample profile (page 29) provides a possible assessment program that this school may offer. The actual program will be similar in terms of balance and variety.

6.3 Assigning Standards

(I) Knowledge and Procedures

The assessment of this criterion involves the recall and use of results and procedures within the contexts of application, technology and complexity. The assessment package will sample all topics and cover the continuum of the contexts.

The assessment package will enable students to demonstrate their ability in the general objectives of this category and the marking schemes/criteria sheets will provide appropriate data.

For each instrument assessing Knowledge and procedures either:

(a) Marks will be awarded and cut-offs applied to arrive at an A+ to E- grade; both the marks awarded and the grade will be recorded on the profile. The actual cut-offs used will depend on the relative difficulty of the instrument and will be supplied, with the instrument, to the panel at Monitoring or Verification.

(b) Verbal standards will be used to arrive at an A to E result which will be recorded on the profile (again A+ to E- will generally be used).Descriptors will be explicitly stated on the criteria sheet of the assessment item as they relate to the A,B,C,D or E standards.This method may apply more appropriately to assessment of Practical Tests, Assignments, Projects or Oral presentations, but may be used throughout.

For tests assessing Modelling and problem solving:

A student’s responses to modelling and problem solving tests may provide some valuable data on the student’s ability to use procedures as they may have shown an ability to use some procedures that they may have not previously shown. This information will be used for borderline students and will be recorded on their profile in brackets. It will not be used in the regular decision making process as this may disadvantage students who are not able to start these problems and therefore do not know which procedures to use. Using this data in the regular process may also skew the level awarded as the procedures used in these tests may not cover the range of topics or contexts.

Awarding Summary Results

Summary results at the end of each semester or exit, are allocated according to the following guidelines describing minimum standards.

Summary Result Performance

A Consistently A’s

B Consistently B’s

C Consistently C’s

D Consistently D’s

E All E-'s

(i) "Latest and fullest" will be considered in awarding summary or Exit levels. For example, a gradual increase in student performance means that a student may be awarded a result reflecting later performance as long as the improvement is sustained.

(ii) Trade-offs might be applied to arrive at the summary result e.g. C,C,A,C,A,A,A,C could equate to a "B" under such a procedure.

(iii) Final A to E results must reflect the relevant descriptors as summarised below:

Knowledge and Procedures

STANDARD DESCRIPTOR

A The overall quality of a student’s achievement across the full range within the contexts of application, technology and complexity, and across topics, consistently demonstrates: accurate recall, selection and use of definitions, results and rules appropriate use of technology appropriate selection and accurate and proficient use of procedures effective transfer and application of mathematical procedures

B The overall quality of a student’s achievement across a range within the contexts of application, technology and complexity, and across topics, generally demonstrates: accurate recall, selection and use of definitions, results and rules appropriate use of technology appropriate selection and accurate use of procedures.

C The overall quality of a student’s achievement in the contexts of application, technology and complexity, generally demonstrates: accurate recall and use of basic definitions, results and rules appropriate use of some technology generally accurate use of basic procedures

D The overall quality of a student’s achievement in the contexts of application, technology and complexity, generally demonstrates: accurate recall and use of basic definitions, results and rules appropriate use of some technology

E The overall quality of a student’s achievement rarely demonstrates knowledge and use of procedures

(II) Modelling and Problem Solving

This criterion incorporates:(a) Modelling(b) Problem solving(c) Investigations

The assessment package will enable students to demonstrate their ability in the general objectives of all three areas but this information will not be collected or recorded separately.

Assessment instruments for this criterion may contain closed items with a limited number of correct answers or open-ended items and the package will cover the continuum of all contexts.

Mathematics C Work Program page - 22 My School

Page 25: 1 - Tripod.comrex.boggs.tripod.com/docs/workprog_mac.doc · Web view9. investigate how to construct the elliptical hole required to be cut out of a sloping roof to fit a vertical

Awarding Standards on Tests

Tests assessing performance on this criterion will contain a number of items ranging from the lower end of the complexity and initiative contexts through to the upper end and these items will usually be closed. In these situations, the following general descriptors will be used for rating each individual item on an instrument.

RATING DESCRIPTORA* The problem is solved and the solution shows evidence of interpretation, analysis, identification of

assumptions, selection, use and synthesis of strategies and procedures where appropriate.A An appropriate method is applied to yield a valid solution. Although a correct solution has not been

achieved, the response shows evidence of appropriate interpretation, analysis, identification of assumptions, selection, use and synthesis of strategies and procedures

B The student has made substantial progress towards a rational solution and the response shows evidence of appropriate interpretation, analysis, identification of assumptions and selection of strategies and procedures

C The student has made a reasonable interpretation of the problem and has selected strategies and/or procedures appropriate to the problem.

D The student has followed basic procedures and/or used strategies appropriate to the problem.E The student is unable to begin the problem or hands in work that is meaningless.

OR The student has provided only an answer.

When these general descriptors are not appropriate for a particular item, specific descriptors will be written which reflect the student's achievement of the objectives of Modelling and problem solving. This will generally be necessary for open ended assessment items. These descriptors will be stated on the assessment instruments.

Once each item has been rated, an overall grade will be awarded for the assessment instrument and this grade will be recorded on the student profile along with the rating for each item. The grade awarded for each instrument will reflect the requirement for the mathematical thinking to be displayed across the range within the contexts. A+ to E- will be used in recording this information.

The minimum requirements for A to E will differ for each instrument and will be included for the panel in all submissions. An example is included here by way of clarification.

Example:A test contains four questions, ranging from a well-rehearsed modelling problem through to a question at the upper end of the complexity and/or initiative continuum

RATING MINIMUM REQUIREMENTA* 1 x a* plus 2 x a’sA 3 x a’sB 2 x b’sC 2 x c’sD 2 x d’sE All e’s

*B would indicate that the student solved at least one question.

NOTE: Tests will be set so that the questions are in order of increasing difficulty. It is acknowledged that the level of complexity is a continuum and within the questions considered complex, there should be a range of difficulty from those that a low HA student should be able to solve to those which would challenge VHA students. In addition, a hash (#) appearing below an item rating indicates that the item is regarded to be a more substantial item than others in an assessment package. For example a “#b” could contribute more towards the student’s final grade than (say) an “a”.

Awarding Standards on Assessment other than Tests

As these tasks will generally be open-ended, task-specific criteria will be written which allow data to be gathered on the achievement of the general objectives of Modelling and problem solving and a single level recorded on the profile. In general, these tasks will give the students the opportunity to explore the strengths and limitations of the model and to refine the model.

Awarding Summary Results

Summary results at the end of each semester or exit, are allocated according to the following guidelines describing minimum standards.

Summary Result Performance

A Generally A’s (with some *’s)B Generally B’s (with synthesis in some items)C Generally C’sD Generally D’sE All E’s

Note: This mechanism shows us students who may have achieved the syllabus requirements for this criterion but the final decision must be made on the overall quality of the work.

Final A to E results must reflect the relevant descriptors as summarized below:

7 STUDENT PROFILESAs described in the previous section, data gathered on a student's performance on each of the criteria will be recorded on an individual student profile.

N.B. All summary results for each criterion are based on assessment items to date for the whole of the current year (see sample profiles). For example, the summary results for Year 11 incorporate the data for both semesters 1 and 2.

The rules for awarding summary grades described in the previous section are designed to identify students whose work may match the syllabus standards. The work of any students who are identified as borderline, both above and below the minimum, will be compared with the syllabus standards before an exit standard is awarded.

An example of a completed profile is provided (page 29). Pluses and minuses have not been used in the example but may be used if required.

8 DETERMINING EXIT LEVELS OF ACHIEVEMENT

On completion of the course of study, each student will be awarded a level of achievement, for each of the three criteria, using the tables in the previous section. These levels are then used to determine each individual student's exit level of achievement.

N.B. The minimum standards table includes allowable trade-offs within criteria I-III, therefore NO TRADING-OFF is permitted BETWEEN the criteria when determining levels of achievement.

The following table gives the MINIMUM performance composite of standards for each level of achievement.

Minimum requirements for exit levels

VHA Standard A in any two exit criteria and no less than a B in the remaining criterionHA Standard B in any two exit criteria and no less than a C in the remaining criterionSA Standard C in any two exit criteria, one of which must be the Knowledge and

procedures criterion, and no less than a D in the remaining criterionLA Standard D in any two exit criteria, one of which must be the Knowledge and

procedures criterionVLA Does not meet the requirements for Limited Achievement

Note: The minimum standards table applies when placing students into a band, it does not apply when ranking students within the band. For example, a student who has the following results:-K & P - A; M & PS - B; C & J - Bwould be an HA overall but would not be placed on the bottom rung of the HA band.

Vectors and Applications (notional time 30 hours)

FocusStudents are encouraged to develop an understanding of vectors as entities which can be used to describe naturally occurring systems.

APPENDIX 3

Equity Statement

Equity means fair treatment of all. In developing work programs from this syllabus, schools are urged to consider the most appropriate means of incorporating the following notions of equity.

Schools need to provide opportunities for all students to demonstrate what they know and what they can do. All students, therefore, should have equitable access to educational programs and human and material resources. Teachers should ensure that the particular needs of the following groups of students are met: female students; male students; Aboriginal students; Torres Strait Islander students; students from non–English-speaking backgrounds; students with disabilities; students with gifts and talents; geographically isolated students; and students from low socioeconomic backgrounds.

The subject matter chosen should include, where appropriate, the contributions and experiences of all groups of people. Learning contexts and community needs and aspirations should also be con-sidered when selecting subject matter. In choosing suitable learning experiences teachers should in-troduce and reinforce non-racist, non-sexist, culturally sensitive and unprejudiced attitudes and be-haviour. Learning experiences should encourage the participation of students with disabilities and accommodate different learning styles.

It is desirable that the resource materials chosen recognise and value the contributions of both fe-males and males to society and include the social experiences of both sexes. Resource materials should also reflect the cultural diversity within the community and draw from the experiences of the range of cultural groups in the community.

Efforts should be made to identify, investigate and remove barriers to equal opportunity to demonstrate achievement. This may involve being proactive in finding out about the best ways to meet the special needs, in terms of learning and assessment, of particular students. The variety of assessment techniques in the work program should allow students of all backgrounds to demonstrate their knowledge and skills in a subject in relation to the criteria and standards stated in this syllabus. The syllabus criteria and standards should be applied in the same way to all students.
