Effectiveness of Remedial Mathematics Supplemental Instruction: a Community College Study.

Sagna, Bakary

The purpose of this mixed method study was to determine if there is a relationship between characteristics of supplemental instructors’ personal traits, teaching skills, subject matter, constructive/active, collaborative learning, effective communication, and their practices (as judged by students) and student success in their remedial mathematics course.

The college Provost was contacted by email to request an authorization to conduct this study in his college. Once approved, the investigator contacted face to face his colleagues to ask their students to participate in the study because they enrolled in a remedial algebra class where the instructor is assisted by a supplemental instructor (SI leader). Sixteen algebra classes were selected, and each were assisted by supplemental instructors. Students’ scores on the pre-test (at beginning of the semester) and post-test (at the end of the semester) were collected to gauge their achievement on both tests. Students completed a questionnaire that asked about their perceptions about their supplemental instructors’ personal traits, teaching skills, subject matter, constructive/active, collaborative learning, effective communication, and their practices throughout the semester. Students’ mean scores difference on the post-test were higher in 62.5% of the sections than on the pre-test.

The evaluation of achievement on both tests, the responses to the questionnaire and comments from students showed that SI leader’s characteristics associated to effective communication/active learning, teaching skills, and personal traits could be contributor to score achievements. The linear regression in the study shows that the three factors did not significantly predict the post-test score. However, the pre-test did significantly predict the post-test score in a remedial Math 20 at the end of the semester (Beta = .47, t (197) = 6.56, p <.05). In addition, the comments in the questionnaire found that students acknowledged their supplemental instructor role in the classroom and during the SI’s weekly sessions.
