NOT designed as a substitute for

attending class

• Link will be posted in next day or

so

• May be clickable, if not try cut-

and-paste or another machine

doesn’t work first time!

• The podcasts for inverted

classroom are in a SEPARATE

folder on Avenue

Course Materials • Text book: David Klein; Organic

Chemistry 1st ed. (strongly recommended)

• Different packages available through bookstore:

• Binder-ready version (BRV): costs less, but lower (if any) resale value

• Applications for mark changes will NOT be accepted beyond one month after the date of posting

11

Grade Corrections

Any changes to term marks must be requested in writing PRIOR to writing the final exam

Submit ALL requests to ABB 301, during Greg Bahun’s office hours. Include the original lab or assignment, a clear indication of the problem, and your student number and email address

Note: Marks for work done in pencil will not be changed

We reserve the right to re-mark any or all parts of the work!

12

Tests Midterm:

Tuesday, May 27th, 6-8 pm

Rooms: TBA, watch web site!

Contains:

multiple choice (~40%)

and written parts (~60%).

Final exam has same format.

Thurs. June 19th, 6-9 pm

Sample test from a previous year are in lab manual, but beware: style of material and questions may vary; also may have arrived at different point.

13

• You get the BEST mark of the weighted average of:

a) Midterm (20%) + Final (50%), or

b) Final Exam (70%) • There is no deferred midterm.

So, if you miss the midterm test, your final grade will automatically be re-calculated to compensate (Final Exam 70%).

• Deferred final is in December • Absolutely no writing at any other

14

Written Assignments

• There are 2 written Take-Home assignments. (See schedule)

• No late assignments will be accepted, as solutions will be posted within hours of deadline (5:00 pm).

• Written assignments MUST be handed-in in the drop boxes in ABB (around the corner from the CHEM office - ABB-156 - look for signs), in the correct slot, by the deadline.

• Slots are labelled by lab section (L01, L02, etc). There is also one for those exempt from the labs.

15

On-Line Assignments • There are 4 on-line assignments offered

through Sapling Learning.

1) allow most questions that can be done on

paper to be performed on a computer;

2) enable one to draw structures, just as will be

done on an exam;

3) grades instantly and provides feedback via

tutor-like hints, allowing one to keep working

with a question to arrive at the right answer;

4) include detailed answer explanations.

NOTE: use of Sapling is voluntary. If you choose to use

this system, you are REQUIRED to enter your student

number, and this and grade information will be held by (a)

third party(ies) outside McMaster University. By selecting

Sapling, you agree that you are entirely responsible for

any consequences.

Neither the instructor nor Greg Bahun are able to help

with problems related to Sapling. You must contact

Sapling directly.

18

Sapling evaluation: • Marks will be based on full

participation in each assignment;

failure to fully participate will result

in default up to 0%. This means

attempting AT LEAST 20 questions

per chapter with a reasonable

degree of success (but doesn’t

have to be perfect)

• Sapling marks are based on

Chapters 1-8

• We will also post these as practice

assignments on Sapling Learning

after closure date

• Problems from remaining chapters

will be available but will not used

for marks.

Participation marks and iClicker: • Spectroscopy is a key practical method to determine

organic structures

• For the first 6 weeks we will cover spectroscopy

twice per week; this will allow you to learn

techniques that you will use in the lab, and to have

lots of time to practice solving spectral problems.

• You will view an on-line lecture PRIOR to coming to

each of the classes (Available on Avenue).

• The last part of the classroom sessions will review

the material you have viewed, and test your

knowledge of spectroscopy through iClicker

questions.

• NOTE: there are LOTS of marks for spectroscopy

during CHEM 2OA3 AND continuing into 2OB3.

Spend serious time on this component!

• Marks available for iClicker:

35

Academic Integrity /

Academic Dishonesty

• Academic Integrity is the standard

• Academic dishonesty consists of misrepresentation by deception or by other fraudulent means and can result in serious consequences.

• e.g. the grade of zero on an assignment, loss of credit with a notation on the transcript (notation reads: "Grade of F assigned for academic dishonesty"), and/or suspension or expulsion from the university.

• It is your responsibility to understand what constitutes academic integrity and academic dishonesty – see the course website for a full description.

36

Examples of academic

dishonesty

The following illustrates only four

forms of academic dishonesty:

•Plagiarism, e.g. the submission of

work that is not one's own or for

which other credit has been obtained

•Improper collaboration in group

work, e.g. copying verbatim of other

students' assignments

•Improper use of Sapling and iClicker

•Copying or using unauthorized aids

in tests and examinations

•Ignoring time limits during a test or

exam

37

Academic Dishonesty

• All cases of suspected academic dishonesty will be followed up with the academic integrity officer

• All findings of academic dishonesty will result in a penalty of at least an F (i.e. a zero) for the work in question

• Please refer to McMaster’s policy regarding academic integrity (particularly appendix 3)

• See also the academic integrity statement on the 2OA3 web site

http://www.mcmaster.ca/univsec/policy/AcademicIntegrity.pdf

38

Important!! • It is the student’s responsibility to

ensure that MSAFs are filed on-line and that subsequent medical slips (and other related documents) are filed with your (Associate) Dean’s Office

• For labs, contact Greg Bahun

• For assignments, once filed, assume it’s done, you will not get a response

• You are also responsible for all information in this lecture (see website), even if you are not in class. Failure to follow procedures will result in lost marks!

39

Course Outline

• Available on-line

• Describes the course content

the lectures
