Performance in mathematics among Senior Secondary School students has remained persistently poor in Nigeria. It is as a result of this that this study examined the effect of group discussion method on achievement in mathematics against the common traditional teaching method. The study adopted the quasi-experimental non-equivalent pretest, posttest non-randomized control group design which involved groups of students in their intact classes assigned to experimental and control group. The population for the study consisted of all Senior Secondary School Mathematics (SS II) students from Delta central senatorial district of Delta state. Multi stage and purposive sampling techniques was used to select a sample size of eighty-seven (87) students from two (2) schools from the population. The experimental group is forty seven (47) students while forty (40) students constituted the control group. Two instructional packages were developed for the study. A validated Mathematics Achievement Test (MAT) was used for data collection. Using KR-20 formula, a reliability coefficient of 0.79 was obtained. Mean and standard deviation were used to answer the research questions while t-test was used to test the hypotheses at 0.05 level of significance. Findings revealed that the experimental group who had their instruction through group discussion was more successful than the control group who had theirs through the common traditional method of instruction. However, there was no significant difference in the achievement of male and female students taught using the strategy. The teaching strategy is therefore recommended for teaching students to improve achievement in mathematics.
