Summary

A picture of students participating in Peer Instruction, from Eric Mazur

This series of questions begins with two questions to be done before class, either as JiTT or homework. Students are then prepared to come to class and engage in in-class peer instruction, building an understanding of the concept of work. This is pulled together by an after-class question that can be used as a homework question or a small-group discussion in a smaller class setting, such as a lab/discussion section, or a small lecture section.

Learning Goals

The goal of these questions is to develop a conceptual understanding of work. The questions probe common misconceptions about work. Students must apply this understanding to a series of richer situations.

Context for Use

These questions are to be used in a sequence: Two pre-instruction questions to be done before class, either as JiTT or homework. The next questions are used for in-class peer instruction. For each question, the students should give individual answers, share these answers in small groups, discuss, and present a concensus answer. There should also be a general class discussion after each question to clarify the material. This is then pulled together by an after-class question that can be used as a homework question or a small-group discussion in a smaller class setting, such as a lab/discussion section, or a small lecture section.

This can be done using from very little technology (show of hands, flash cards) up to an infrared student response system.

Students should have an introduction to work from the reading done with the pre-class questions.

Teaching Notes and Tips

Students must come to class prepared, and be engaged in the in-class activity. Peer instruction has proven to be an effective tool for engaging students.


Assessment

The students' response to the follow-up question will indicate level of understanding. This activity is usually followed up by a lab activity, and qualitative as well as quantitative questions are asked in homework and exams.
