EFFECT OF BRAINSTORMING, JUST-IN-TIME AND DEMONSTRATION TEACHING TECHNIQUES ON STUDENTS’ LEARNING OUTCOMES IN DIGITAL ELECTRONICS IN COLLEGES OF EDUCATION IN NORTH-WEST, NIGERIA

Abstract

ABSTRACT 2

The study identified the effects of brainstorming, Just-in-time Teaching (JiTT) and demonstration teaching techniques on students' cognitive achievement, skill achievement, interest and retention of students in colleges of education in North-West Nigeria. Four research questions were raised and answered as well as four hypotheses were formulated and tested at 0.05 level of significance. The study adopted pretest– posttest non-equivalent control group design of quasi-experimental study alongside, 3×3 factorial research design. The study was conducted in North-West, Nigeria. The population of this study comprised of the entire 142 Nigerian Certificate in Education (NCE) III electrical/electronic students in all the Colleges of Education in the study area offering technical education. Due to the manageable size of the population of the study, there was no sampling of subjects. The Colleges of Education in the study area were assigned to control and experimental groups I and II using purposive and simple random sampling techniques. The instruments used for data collection include: Digital Electronics Cognitive Achievement and Retention Tests (DECART), Digital Electronics Skill Achievement Tests (DESAT) and Digital Electronics Interest Inventory (DEII). The instruments were subjected to face and content validation by three experts. The reliability co-efficients of: DECART was determined as 0.78 using Kuder-Richardson 20 (K-R 20), DESAT was determined as 0.81 using Kendall’s tau coefficient of concordance and DEII was determined as 0.83 using Cronbach Alpha. The collection of data for the study was achieved through physical administration of the instruments by the lecturers involved in the study. The study employed the use of descriptive statistics using mean and inferential statistics using Analysis of Covariance (ANCOVA) to analyze the data. The study found out that, brainstorming teaching technique had positive effect on the cognitive achievement (𝐗=79.76) and the retention of students (𝐗=75.27) in digital electronics, demonstration teaching technique had positive effect on the skill achievement of students (𝐗=77.95) in digital electronics and JiTT technique had positive effect on the interest of students (𝐗=84.79) in digital electronics. The study also revealed that, there was significant difference (Sig. 0.00) between the mean cognitive and skill achievement, interest and retention scores of students taught digital electronics using brainstorming, JiTT and demonstration teaching techniques. The study recommended among others that, digital electronics lecturers should adopt the use of: brainstorming teaching technique to enhance students' cognitive achievement and retention, JiTT technique to stimulate students' interest and demonstration teaching technique to enhance students' skill achievement.
