A PHILOSOPHY OF ASSESSMENT
(and evaluation)
Peter Gow
Assessment/P. Gow/BCDS 2006
Assessment IS curriculum
(and vice versa)
Assessment/P. Gow/BCDS 2006
Why assess?Assessment has several purposes, listed here in
order of importance: To improve student learning, by giving students
meaningful feedback on their mastery of skills and content knowledge
To improve teaching, by providing teachers with a means of measuring and/or describing individual and aggregate student learning
To facilitate communication about ongoing learning To audit student performance
Assessment/P. Gow/BCDS 2006
What does assessment look like?
Assessment is a broad range of methods and techniques. A few examples:
elaborate long-term, interdisciplinary, collaborative projects
essays paper-and-pencil quizzes standardized multiple-choice tests The assessments you use should be based on the
skill(s) or knowledge that you mean to assess.
Assessment/P. Gow/BCDS 2006
How would you? Assess students’ knowledge of the parts of a cell Assess students’ understanding of how the parts
of a cell function Assess students’ understanding of the functions
of the three branches of the United States government
Assess students’ ability to read and understand a novel in Spanish
Assess students’ mastery of a list of vocabulary words
Assessment/P. Gow/BCDS 2006
Or? Assess students’ understanding of Chinese
culture Assess students’ ability to solve equations
containing inequalities Assess students’ ability to apply the mathematical
notion of “inequality” to a real-world situation Assess students’ understanding of the Civil Rights
Movement of the 1960s Assess students’ readiness to study calculus
Assessment/P. Gow/BCDS 2006
Or? Assess students’ ability to understand a graph Assess students’ ability to write persuasively Assess students’ intellectual curiosity Assess students’ ability to make connections
between the film American Beauty and The Great Gatsby (the book, of course)
Assess whether your students understand the utility of the binomial theorem
EFFECTIVE ASSESSMENT
Assessment/P. Gow/BCDS 2006
Effective assessment
INTENTIONALLY FOCUSES ON WHAT MATTERS: It asks students to present evidence of the important learning you want to have taken place.
“Assess what you value; value what you assess”—Grant Wiggins.
Assessment/P. Gow/BCDS 2006
Effective assessment HAS NO SECRETS: It begins with a clear
statement of the things being assessed and the criteria by which assessment is being made; these should (of course) match the important learning goals.
PROVIDES FEEDBACK: It gives the student clear direction as to how to improve future performance, and it gives the teacher information with regard to individual and group learning.
Assessment/P. Gow/BCDS 2006
Effective assessment CONNECTS AUTHENTICALLY TO CONTENT:
The work asked for addresses plausible and authentic problems or questions that relate to the desired learning. The more “real” the problem, the more engaged students are likely to become.
FITS THE LEARNING: The method matches the type of learning you want to have taken place; you wouldn’t assess a student’s French accent by means of a written quiz.
Assessment/P. Gow/BCDS 2006
Effective assessment IS FAIR: The method is designed to give
each student an equal opportunity to succeed.
IS SAFE: The method is designed to encourage questioning and risk-taking.
IS CREDIBLE: The method is designed to relate in a clear and explicable fashion to the total learning experience.
Assessment/P. Gow/BCDS 2006
Effective assessment IS VARIED: It comes in a variety of flavors
for each unit, topic, or course. The broader the range of assessments given, the more complete and useful a picture of learning will be developed—and the greater the range of individual student strengths, weaknesses, and learning styles that will be tapped and revealed.
Assessment/P. Gow/BCDS 2006
Effective assessment IS TIMELY: Evaluation takes place close to the
learning experience, and feedback and critique are received in a time frame that allows students to use it to improve performance.
IS MANAGEABLE: The average human teacher can use it in a timely and effective fashion; writing may be a valuable skill, but the solution to every math problem 1-29 (odd) doesn’t need to be presented in essay form.
Assessment/P. Gow/BCDS 2006
Effective assessment Follows a trajectory based on the cognitive
complexity of the learning being assessed. Use the ASSESS-O-MATIC to plan the assessment tasks for a unit or to design a text or examination based on an ascending hierarchy of complexity.
THINGS TO THINK ABOUT IN
ASSESSMENT DESIGN
Assessment/P. Gow/BCDS 2006
AUTHENTIC ASSESSMENT:Engage students and raise the stakes
Write a letter to…(and mail it) Field study…(find a consulting expert) Imagine you are … Solve this problem… Debates… (bring in an outside judge) Write for or present to an actual audience
(parents, outsiders, peers) Community role play (“Our town/school has
to solve the problem of…”)
Assessment/P. Gow/BCDS 2006
More reflective assessment Portfolios—gather a student’s work, use it as the
basis for improvement, ask the student to reflect; invite an audience (parents, advisor) to share the reflection
Regular self-assessment modules or exercises at the end of each topic, unit, or term—written or conference-based
HINT: Use your stated criteria—your “standards”—as the basis for this self-assessment.
Assessment/P. Gow/BCDS 2006
PERFORMANCE STANDARDS These are the criteria by which the quality of
student learning will be assessed: What will this learning look like? What will be good evidence of this learning? What will excellent performance look like?HINT: Ask your students for help!! (“What are the
characteristics of an excellent essay/math homework/oral presentation?”)
ALSO: Check out the Parker “Criteria for Excellence”—great language to use!
Assessment/P. Gow/BCDS 2006
RUBRICS in two slides Evaluation rubrics are a tool combining
stated standards for LEVELS of performance with clearly delineated CATEGORIES of performance
E.g., They show students what excellent work is
supposed to look like and tell them what parts of the work are important
Assessment/P. Gow/BCDS 2006
Rubrics are Easy to create--ask your students to describe
excellent work or to tell you what should be important on a certain kind of work
Easy to use--they save time and eliminate some decision-making about what matters Danger! Posters, videos, …
Great ways to give clear, specific feedback to students--and they help the teacher see what is working, as well
Assessment/P. Gow/BCDS 2006
Why grades? To provide a record of student performance To provide evidence of a progression of
learning To sort out a student’s performance against
a standard To give students FEEDBACK on their
performance
Assessment/P. Gow/BCDS 2006
Weighting grades Give a piece of work a weight proportionate to its
relative degree of importance and difficulty Quizzes worth less than tests Big projects worth more than homework Use simple grading system (check, check-plus) for simple
work
Take a tip from your college professors, and assign specific weights in advance
Don’t forget to weigh in class participation
Assessment/P. Gow/BCDS 2006
Just for Middle School… The dreaded grid:
Think of a “standard”--what you want students to be able to do
Then think of how to describe progress toward that standard:
Beginning Working Approaching Meeting
and at last, “Proficient”
Assessment/P. Gow/BCDS 2006
Rubrics to grades Top level of performance = A Satisfactory but nothing special = C(+) Really unsatisfactory = NP Not usually a mathematical equivalency--
12/16 may not = 75% or C; may be closer to B-
You gotta do what works for you The 16-point rubric trick
Assessment/P. Gow/BCDS 2006
Keeping a grade book Your gradebook is PRIVATE Your gradebook should allow plenty of space to
describe performance tasks and to keep track of each student’s grades
If using a paper gradebook, skip lines between kids
Consider keeping a more descriptive kind of record--a notebook with a page for each student; comment on work alonmg with grading it
Assessment/P. Gow/BCDS 2006
“Averages” If you use a spreadsheet or “electronic grade
book,” make sure you have an escape clause--just because a number was arrived at by a computer calculation doesn’t mean that number is “true” or objective--because the grades you entered are subjective
Remember the “feedback” function--grades send a message to students; it’s okay to have that message be an encouraging one
Assessment/P. Gow/BCDS 2006
Evaluating effort Danger, danger! (Did you ever fool anyone?) Evaluate effort based on clear standards that you
feel comfortable about--work completed, details included, …--against clearly stated criteria
You probably can’t really ever know how hard a kid is working in other ways
