Effects of Videotaped and Text Based Computer Assisted Instruction on Student' Performance in Blocklaying, Bricklaying and Concreting in Technical Colleges in Niger State, Nigeria: International Journal of Research in Science, Technology and Mathematics Education (IJRSTME) 5,(1) 11-21 ISSN: 2354-3590

Abstract

The study investigated the effects of videotaped and text-based computer assisted instruction on students' performance and interest in Blocklaying, Bricklaying and Concreting (BBC) in Technical colleges in Niger State. The study adopted a quasi-experimental research design of pretest, posttest non-equivalent control group design. The population of the study comprised all the 190 NTC II students of BBC in the seven technical colleges in Niger State for 2016/2017 session. The total population of the student was used for the study. The instrument for data collection were, Blocklaying, Bricklaying and Concreting Performance Test (BBCPT) and Blocklaying, Bricklaying and Concreting Interest Inventory (BBCII). The BBCPT was drawn based on a table of specification that covered six levels of Taxonomy of cognitive Domain. The BBCPT and BBCII were subjected to face validation and content validation by three experts. Test re-test reliability technique was carried out to determine the internal consistency of the BBCII items and the result obtained was 0.83. Mean and standard deviation were used to answer research questions, while Analysis of Covariance (ANCOVA) was employed to test the hypotheses at .05 level of significance. The study discovered that Videotaped and text-based computer assisted instruction were effective in improving students' performance in BBC but videotaped computer assisted instruction was found to be more effective in improving students performance than the text-based computer assisted instruction. Based on the findings, it was recommended among others that Videotaped and text-based computer assisted instruction should be adopted and used by BBC teachers for teaching and learning of BBC in technical colleges. National Board for Technical Education (NBTE) and Science and Technical Schools Board (STSB) should consider it necessary in the curriculum content adaptation to computer assisted instructional strategies for teaching BBC at technical college level in the next review of the curriculum.
