EFFECTS OF THINK-PAIR-SHARE AND PROBLEM BASED LEARNING METHODS ON STUDENTS' ACHIEVEMENT IN BASIC SCIENCE AND TECHNOLOGY IN MINNA NIGER STATE.

Abstract

Abstract: The study employed a quasi-experimental research design. Specifically, the non-equivalent control group design was used. The study m-oj carried out in Minna Metropolis. The population of the study consisted of all the 8,225 junior secondary school students in junior secondary schools in Minna Metropolis. Simple random sampling technique was used to select 240 students from 4 junior secondary schools in Minna. The instrument used for data collection in this study was a 40 item Basic Science and Technology Achievement Test (BSTA I). The Basic Science and Technology Achievement Test (BSTA T) was face and content validated by two experts in Department of Science Education, Federal University of Technology, Minna. Reliability test was obtained by analyzing the responses obtained from the trial testing among JSS II students from Junior Secondary School, Bosso which is outside the research area. This method w used to estimate the stability of the items since the same instrument mas used for both the pretest and the posttest. An index of internal consistency of 0.82 was obtained using Kudder-Richardson formula 20 (K-R 20). The K-R 20 was applied since the items were dichotomously scored. The data collected were analyze using mean and standard deviation to answer the research questions and analysis of co-variance (ANCOVA) to test hypotheses at 0.05 level of significance. Findings from the results, m-called that moderate performance difference exist between the experimental and control group subjects. Male students had higher mean achievement compare to their female counterparts. There was a significant difference in the mean test scores of students taught with the three methods of teaching basic science and technology. From the findings, the study therefore recommend that teachers should avoid the continuous use of conventional lecture method in the teaching of basic science and technology and attention should be adequately paid to the female folds by advising teachers of basic science and technology to apply both the think-pair-share and problem based learning among others.
