EVALUATION Mastering Chemistry Homework (HW) CHEM 1A03/1E03 will make use of Mastering Chemistry for online homework assignments (HW). Mastering Chemistry provides tutorial style problems providing built-in hints based on student response (if incorrect). Access to Mastering Chemistry is bundled in the NEW Petrucci textbook package or available separately through the Campus Store or the Mastering Chemistry widget on the Avenue homepage for this course. Participation in the Mastering Chemistry homework assignments is optional (see final mark calculation), but strongly recommended. There are six HW assignments during the term. Only the top 4 of the 6 assignments are used in the final grade calculation. Answers for each homework assignment are entered via Mastering Chemistry. All homework assignments must be submitted by December 9th at 11:59 pm. We have provided a schedule of suggeste suggested d completion times on page 8. We encourage you to follow this schedule to be better prepared for the tests and exams.

QUIZZES Twelve quizzes are available during the term through Avenue. Each quiz will be available a minimum of two days before its suggested due date (shown on page 8). We encourage you to follow this schedule as the content for each quiz will be on the subsequent tests and exams however, the final day to submit all quizzes is December 9th at 11: 11:59 59 pm pm. You will have 3 attempts for each quiz. Only the top 10 of 12 marks are counted towards your final grade.

ONLINE LABORATORIES A series of lab simulations will be offered via the Hayden-McNeil Digital Labs platform (HMDL). There are five simulations, each of which has a post-lab assignment. The deadlines for these assessments (Lab 1, 2, 3, etc.) is found on page 8. The post-lab assessments will be available a minimum of two weeks before their deadline posted on page 8. The simulations for all experiments will be available from the start of term.

TESTS Two 90-minute term tests are scheduled during the semester (see page 8 for dates and times). The tests will be offered on Avenue using the quiz tool and may use proctoring software. Pre-existing conflicts should be discussed with the course coordinator ([email protected]) a minimum of 1 week in advance of the test date. Please note, that a longer amount of time may be given to all students to accommodate atypical test-taking environments and challenges with internet connectivity. This increase in test duration should not be interpreted as the test being more difficult. The number of questions and their difficulty will reflect a standard 90-minute test.

EXAMINATIONS Final Examination (2. (2.5 5 hours): is scheduled for December by the Registrar’s Office and will test all course content from the Fall term. This examination must be written to pass the course. The exam will be administered using the quiz tool in Avenue and may use proctoring software. Pre-existing conflicts should be discussed with the Registrar’s office once the exam timetable is released (usually by November). Please note, that a longer amount of time may be given to all students to accommodate atypical test-taking environments and challenges with internet connectivity. This increase in exam duration should not be interpreted as the exam being more difficult. The number of questions and their difficulty will reflect a standard 2.5-hour exam.

Marking Scheme Three weighting options are shown below. Each student will automatically receive the highest grade of the three calculated grades. Note that Mastering Chemistry is an optional component in all three weighting options. This means that students who do not participate in, or score well, on this component (relative to their final exam score) will automatically have the weight transferred to their final exam.

Note 1: Students must complete and submit a post-lab assignment for a minimum of 4 laboratory experiments to pass the course. Post-lab assignments that are found to be in violation of McMaster’s academic integrity policy are not counted as a submission. Note 2: To obtain credit for CHEM 1A03/1E03, students must complete a minimum of 75% of the weight of the course work as shown in Option 1. This 75% must include both the final exam and laboratory components. Students who miss both Test 1 and Test 2 will not be able to meet this 75% threshold. Note 3: The instructor(s) and university reserve the right to modify elements of the course during the semester. The university may change dates and deadlines for any or all courses in extreme circumstances. If either type of modification becomes necessary, reasonable notice and communication with the students will be given with explanation and the opportunity to comment on changes. It is the responsibility of the student to check their McMaster email and course websites weekly during the term and to note any changes.
