The study investigated the effect of Scaffolding Instructional Techniques (SIT) on academic achievement among junior secondary school (JSS) mathematics students in Obollo-Afor Education Zone of Enugu State. The study was guided by two research questions and two null hypotheses. The design of the study was quasi-experimental research design; specifically non-equivalent control group. The population of the study comprised of 7,842 JSS 1 students in the 48 public secondary schools in Obollo-Afor Education Zone of Enugu state. The sample size of the study was 178 JSS 1 students from four (4) sampled schools drawn using proportionate stratified sampling technique. Mathematics Achievement Test (MAT) was the instrument used for the study. The instrument was validated by three experts in Department of Science Education (one from measurement and evaluation unit and two from mathematics education unit), University of Nigeria Nsukka. The instrument was trial tested on a sample of 20 JSS 1 students from the same zone outside the sampled schools and the reliability index was 0.79 using Kuder Richardson 20 formula. The data collected analyzed Mean and standard deviation to answer the research questions and Analysis of Covariance (ANCOVA) to test the null hypotheses at 0.05 level of significant. The results of the study revealed that the students taught mathematics using Scaffolding Instructional Techniques (SIT) achieved higher than the group taught without Scaffolding Instructional Techniques (SIT). There was no significant difference in the mean achievement score of male and female students in mathematics as result of Scaffolding Instructional Techniques (SIT). Based on the findings, it was recommended that mathematics teachers should use Scaffolding Instructional Techniques (SIT) while teaching the subject. Moreover, seminars and workshops should be organized by government for mathematics teachers on this technique for its proper application in mathematics classrooms.
