Development and Evaluation of Task Instructional Sheets for Teaching Electricity/Electronics Skills in Nigerian Colleges of Education

Abstract

The study was conducted to develop and evaluate task instructional sheets for teaching Electricity/Electronics students in Colleges of Education in Nigeria. Four research questions were formulated guided the study. A pretest and posttest non-equivalent control group design was adopted for the study. A sample of 320 Electricity/Electronics and final year students drawn using random sampling technique from four Colleges of Education in South-South, Nigeria was used for the study. Two schools each were randomly assigned to experimental and control groups and the available data showed that each Electricity/Electronic final year class of each school contains an average of 80 students. The experimental and control groups were taught the (TEE 313) Electricity/Electronics devices and measurement by their regular Electricity/Electronics lecturers. An instrument, the Electricity/Electronics Achievement test (EEAT) was developed by the researchers, validated by three experts and used for date collection. The reliability coefficient of the instrument was 0.85. The research hypotheses were tested at .05 using analysis of covariance (ANCOVA). The results of data analysis showed that the task instructional sheets were superior to the expository method and high ability level.
