DOWNLOAD EBOOKIn this study, the performance of students in an Honors Integrated Math Three course who received descriptive, written feedback on formative quizzes was compared with the performance of students who did not receive this feedback on these quizzes. The study employed a quasi-experimental nonequivalent group design in which the researcher taught two sections of this math course. One section was designated as the experimental group (n = 12) and the other was designated as the control group (n = 24). Data was collected via a pretest and posttest and was analyzed using quantitative and qualitative methods. For the quantitative data analysis, an ANOVA was performed on posttest overall mean scores and on the posttest mean scores of each learning goal of the instructional unit. The ANOVA revealed no statistically significant difference between the experimental and control groups' posttest scores. The qualitative data analysis in this study employed the constant comparative method, which involved the coding of both groups of students' responses on the posttest. Three themes appeared in the students' responses. One theme that evolved was that both groups were equally likely to not answer a question or to not provide an explanation in their responses on the posttest. This finding shows that the descriptive, written feedback on formative quizzes did not encourage the participants to take risks on tests. A second theme was that the descriptive, written feedback reduced the variation of the experimental group's responses on the posttest to more specific and focused answers. In particular, students in the experimental group were more likely to use mathematical language and algebraic explanations in their responses than the control group. The last theme was that students in the experimental group demonstrated a better understanding of the relationship between a function's domain and points of discontinuity than the control group. This finding indicates that the descriptive, written feedback influenced the participants' understanding of this relationship.
