Week 7 (2/26-3/1)

If you are struggling with burnout or have fallen behind in the course in some way, please consider reaching out to the Student Assistance Center to get connected with resources to help you take care of yourself and get back on track. You may also consider looking at the mental health resources link. It may be helpful to look at resources for studying and test taking from DGS and DRES.

If you are encountering difficulties with the math in this course, we encourage you to utilize online resources and office hours for assistance. This OpenStax chapter on right triangles is useful for reviewing when to use sine, cosine, and tangent; and this chapter reviews methods for solving two equations with two unknowns.

Academic Integrity

Use of AI Tools

This course permits you to use artificial intelligence (AI) tools, such as chatbots, text generators, paraphrasers, summarizers, or solvers, to get guidance on assignments except for quizzes and exams, as long as you do so in an ethical and responsible manner. Essentially, you can think of these tools as ways to help you learn but not to entirely create work for assignments like discussion problems, prelabs and labs, and James Scholar Projects. AI is more like your tutor or TA, not a replacement for your independent thinking.

This means that you must:

You are accountable for any mistakes or errors made by the AI tool. Do not rely on the AI tool to produce flawless or correct results. Always check and edit the output before submitting your work. If you discover any inaccuracies or inconsistencies in the output after submission, notify the instructor immediately and correct them as soon as possible.

Using AI tools in an unethical or irresponsible manner, such as copying or paraphrasing the output without citation or transparency, using the output as your own work without verification or integration, or using the output to misrepresent your knowledge or skills, is considered a violation of Academic Integrity in Physics 101. If you have any questions about what constitutes ethical and responsible use of AI tools, please consult with the instructor before submitting your work.
