Effects of Prior Conception, Exploration, Discussion, Dissatisfaction and Application (PEDDA) Model and PEDDA-Animated Instructional Model on Achievement of Pre-Service Chemistry Teachers’

Abstract

This study sought to determine the effect of Prior conception, Exploration, Discussion, Dissatisfaction and Application (PEDDA) model and PEDDA-ANIMATED instructional model on achievement of male and female pre-service chemistry teachers in Delta State. Two research questions and three hypotheses that were tested at 0.05 level of significance guided the study. The population of the study consisted of seventy two (72) pre-service chemistry teachers and the sample for the study was made up of forty (40) pre-service chemistry teachers drawn from the only Federal College of Education and one State College of Education (using simple random sampling- balloting technique) located in the State. A quasi- experimental design was used for the study because intact classes were used. The two Colleges of Education were randomly assigned to PEDDA instructional strategy and PEDDA- ANIMATED instructional strategy using toss of coin. Electrochemistry Achievement Test (EAT) developed by the researchers and found to be valid and reliable was used for data collection. The groups received pre-test and post-test independently. The research questions were answered using mean and standard deviation while Analysis of Covariance (ANCOVA) was used to test the hypotheses. The findings showed that there was no statistical significant difference in the mean achievement scores of pre-service chemistry teachers’ taught electrochemistry with PEDDA and those taught using PEDDA-ANIMATED instructional strategy and there was no interaction of instructional strategy with gender among others. Based on the findings it was recommended among others that the National Commission for Colleges of Education (NCCE) should incorporate PEDDA and PEDDA –Animated instructional strategies in the National Certificate of Education (NCE) minimum standards as part of the strategies for teaching especially the science courses.
