This quasi-experimental study examined the effects of participation in a Supplemental Instruction (SI) program on student test performance in a second-level developmental mathematics class in a four-year university setting. This research deviated from past research on Supplemental Instruction in that it examined effects of the program at the end of each test block rather than at the end of the course only. The quasi-experimental design was precipitated by an inability to control factors of participation and limited sample size. Test data were analyzed using analysis of variance; final course grades were analyzed using chi-square.
The UNT Libraries serve the university and community by providing access to physical and online collections, fostering information literacy, supporting academic research, and much, much more.
