There are NO alternatives for lab exams. If you have a legitimate excuse to miss a lecture exam, the instructor needs to know, before the beginning of the exam time, and other arrangements need to be made prior to the exam time. For the most part, lab and lecture exams are on the same days. Observe lab safety and cleanliness procedures. Participate fully in all class activities.
People learn best when they take responsibility for their own learning.
You need to accept that responsibility. Be open to feedback on the course and be flexible in order to make appropriate changes to meet student needs. Be fair in assessment of student learning. It is my hope and expectation that we will all work together to make this course an outstanding experience for all involved. Lecture exam III is Tues.
