Course and Departmental policies, including Academic Dishonesty:

1. Student collaboration

We strongly encourage students to work together in preparing for class and laboratory. Small group discussions are very useful in generating ideas that aid in problem solving and stimulate learning. Problem solving is an important part of chemistry and often it is the best way to learn material in chemistry courses. You are encouraged to work together on practice problems from the text. On individual work that is used for course or laboratory grading, however, any assistance that you give or receive from another student must be limited to correcting errors in the data as recorded in the laboratory. It is not appropriate to give your work, including spreadsheets, to another student for copying or comparison. Your course instructors are always eager to help – please ask us!

All material that you submit for a grade must be the result of your own thoughts and work. Graded work includes exams, quizzes, lab reports, and on-line homework. Lab reports and graded homework are just as important with regards to academic dishonesty as tests. Science advances through the honest and careful reporting of laboratory work. Note that this policy includes both calculations and answers to questions in laboratory write-ups. In lab, your collaboration ends with collection of data.

Academic dishonesty can take many forms including, but not necessarily limited to:

  • Looking at or copying material from another student’s work, or allowing another student to copy any of your work.
  • Using any sources or materials during an exam that are not expressly allowed by the instructor, creating such materials and leaving them in a location where they might be used by you or another student (all such materials should not be brought to the exam; they may not be on the floor, hidden in your exam, written on your hand, programmed into an electronic device, left in the bathroom, halls, or surrounding area, etc.).
  • Altering your exam in any way after it is returned when asking for regrading of a portion of an exam.

The college statement on academic integrity:  Honesty, integrity, and personal responsibility are cornerstones of a Colby education and provide the foundation for scholarly inquiry, intellectual discourse, and an open and welcoming campus community.  These values are articulated in the Colby Affirmation and are central to this course. Students are expected to demonstrate academic honesty in all aspects of this course.

Academic dishonesty includes, but is not limited to: plagiarism (including quoting sources without quotation marks around the borrowed words and a citation); presenting another’s work as one’s own; buying or attempting to buy papers or projects for a course; fabricating information or citations; knowingly assisting others in acts of academic dishonesty; violating clearly stated rules for taking an exam or completing homework; misrepresentations to faculty within the context of a course; and submitting the same work, including an essay that you wrote, in more than one course without the permission of instructors.

Academic dishonesty is a serious offense against the college. Sanctions for academic dishonesty are assigned by an academic review board and may include failure on the assignment, failure in the course, or suspension or expulsion from the College.

For more on recognizing and avoiding plagiarism, see the library guide:

2.  Extra help

Please see Professor King or Madison as soon as possible if you have any questions about course or lab material. Help is also available at the Chemistry Help Center, staffed by experienced and knowledgeable chemistry majors, which is open four evenings per week in Keyes 104 (M-Th, 7:30-9:30pm).  These students will be happy to answer questions and help with problems.  If you feel the need for further help (i.e. after you’ve met with your Professor and tried using the Chemistry Help Center), tutors are available – see Lisa Miller (Keyes 310; [email protected]) to make arrangements.

3.  Exams

There will be three one-hour exams this semester outside of class time (see dates above) and a final exam during the exam period. To allow for universal access, all students may take up to two hours to complete the one-hour exams. Exam questions may come from lecture, lab, the text, and/or homework and will be a mix of multiple choice, mathematical problems, and short answers. Please note that you must show your work on arithmetical problems for credit and partial credit.

Students are required to take all exams, and there are NO MAKE-UP EXAMS. If a student expects to be away for an official College activity, we will arrange for exams to be administered by a coach or other non-student person that accompanies the student. It is the responsibility of the student to let your professor know, well in advance, of any possible trips and to arrange with a person (for example, your coach) to administer the exam.

You must have your advising Dean contact your course instructor if you want to be excused from an exam for a medical or family emergency. You must authorize the Health Center to report your illness to your advising Dean. The grade for an unexcused missed exam is zero. The grade for an exam missed due to an excused absence will be calculated based on your three remaining unadjusted exam grades, normalized by the class average. Students with documented learning differences should follow college policy to arrange for accommodations during the first two weeks of the semester.

Important note:  To encourage students to perform to the best of their abilities and to work towards improvement, all hour exams will be adjusted based on future test scores. All hour-exam grades will be adjusted upwards by replacing the exam score with the average of that exam grade and the subsequent unadjusted exam grade (the final exam will be used to adjust the third exam grade). Note that this recalculation is automatic, and will only be applied if it improves your grade.

4. Homework assignments

The homework portion of your grade will be derived from an online homework application, “Mastering Chemistry.” You must purchase an access code from the bookstore (bundled with new textbooks) or online (directly through the homework website) and set up an account at according to the instructions that you can download from the CH141 website. There will be graded online homework problems due each week.  The exact due date and time will be posted on Mastering Chemistry. For each assignment, be sure to view the grading details. These assigned problems will predominantly involve quantitative problem solving. To compensate for on-line access issues, forgetfulness, busy student schedules, and electronic dogs that may eat your homework, we will automatically drop the three worst homework grades.

In addition, optional practice problems will be assigned from the back of the textbook chapter and online through Mastering Chemistry. Work through as many of these problems as necessary to make sure you have a good grasp of the material. The key indicator of success in this course is the ability to work through problems without depending on an answer key or on the online ‘hint’ feature.

5. Electronic Devices

Electronic Devices, such as laptop computers, cell phones, and tablets can be useful educational tools to facilitate learning. However, used inappropriately, electronic devices can be a significant distraction to other members of your class. We request that students be respectful of the instructor and other students when using electronic devices during lecture or lab.
