Assessing the Potency of Scaffolding and Demonstration Instruction Methods on Student’s Achievement in Technical Colleges in Akwa Ibom State

Abstract

This study was designed to determine the difference in students’ achievement in Block-laying and Concreting using Scaffolding and Demonstration Instructional Methods in Technical Colleges in Akwa Ibom State. This was an attempt to test the potency of scaffolding as a teaching method in technical education having found it useful in other courses. A Quasi Experimental design was adopted for the study. Two hundred and forty six senior technical two students offering Block-laying and Concreting from six public Technical Colleges in Akwa Ibom State constituted the population of the study. A sample of 90 subjects drawn through simple random sampling technique of three out of the six public Technical Colleges in Akwa Ibom State was used for the study. The Experimental and Control groups were taught Block-laying and Concreting topics from NABTEB syllabus and tested by the regular Research Assistants. An instrument titled Block-laying and Concreting Achievement Test (BCAT) developed by the researcher and validated by three experts was used for data collection. The reliability co-efficient indices of the instrument using Cronbach’s Alpha ranged from 0.86 to 0.96. The independent t-test was used in testing hypothesis. The result showed that: Scaffolding Instructional Method can be used in teaching workshops-based subjects such as Block-laying and Concreting. Based on these findings it is recommended, among others that institutions training technical teachers should incorporate Scaffolding Instructional Method as one of the method in their curriculum used in training student-teachers in block-laying and concreting.
