This article will concentrate on the use of ConcepTests in a course on College Algebra and some reasons why I think their use is effective in enhancing student learning. I use them as an aid in promoting student discussion and learning of mathematical concepts rather than as a means of determining a student's grade. It is really for formative assessment — giving both the instructor and students a means of assessing how well the students are understanding a concept or procedure. The ConcepTests used in the article are found in a ConcepTest Supplement to an algebra textbook, Robinson, Lomen, et al. [70].

Method

Because of the variety of forms these questions may have, instructors can use them in a manner that fits comfortably with their teaching style. Four possible ways are:

1. 1. As an introduction to a topic. This works especially well if the topic is closely related to a previous lesson, or is something with which most students have some familiarity.

2. 2. After presentation of a specific topic. Here a ConcepTest may be used to see if the students have grasped the concept, or if the topic needs more discussion or examples.

3. 3. As a review of material that has been thoroughly discussed.

4. 4. As a means of checking homework. Here studentswork on themoutside of class, either individually or in groups. Then in class, students can vote on their results and discuss the strategies used in obtaining their answers.
