Economics as a subject is one of the sciences that is required for any nation's development, but its teaching and learning has not being easy, which has resulted in poor student achievement. In search of solutions, this study has considered the reflective-reciprocal teaching technique and investigates its effectiveness on student teachers' academic achievement and attitude in the subject. Four Null hypotheses were formulated to guide this study. The study adopted the quantitative method of inquiry, using specifically a pre-test, post-test quasi-experimental design. Three Colleges of Education out of 22 federal Colleges of Education in Nigeria were purposively selected based on certain criteria to be the sites for the study. The sample for the study consisted of 178 second year Economics student teachers; the participants were randomly assigned to an experimental group or a control group. The pre-test scores of the participants was obtained using achievement test, numerical ability test questionnaire. Participants in the experimental group were exposed to six weeks of teaching using the reflective-reciprocal teaching strategy while participants in the control group were exposed to the traditional method of teaching. The quantitative data collected was analyzed using descriptive statistics in the form of proportions, frequencies, means and standard deviations, independent t- tests and paired t-tests to compare differences between two groups, Analysis of Covariance (ANCOVA) and ANOVA for repeated measures. The Multiple Classification Analysis (MCA) aspect of ANCOVA was used to determine the magnitude of the performance of the groups. The findings of the study show that there exists a significant difference in the achievement of student-teachers in Economics when taught using reflective-reciprocal teaching strategies compared to the conventional method. Based on the findings of this study, it is recommended that Economics student teachers should make effective use of reflective-reciprocal teaching strategies in the classroom in order to further enhance the achievement of their students in the subject. In addition, the Federal and States Ministries of Education should encourage the use of the reflective-reciprocal teaching strategies by organizing workshops for educational trainers and teachers to better equip them in the use of the reflective-reciprocal teaching strategy. The use of reflective-reciprocal teaching strategies should be encouraged in other teaching subjects as well. / Curriculum and Instructional Studies / M. Ed. (Didactics)
