Effects of Three-Pair-Strategy using VARK Model on Performance and Retention in Electrolysis among Senior Secondary School Students in Zamfara State, Nigeria.

Abstract The study assessed the Effect of Three Pair Strategy on Academic Performance and Retention in Electrolysis among Senior Secondary Schools two (SS2) students, Two research questions and two null hypothesis guided the study, The study adopted a quasi-experimental research design The population was 25,335 from 189 public schools SS2 students offering chemistry in Zamfara State. A sample of 70 students drawn from 2 schools was selected using multi- stage sampling techniques by balloting, One instrument was used for data collection Electrolysis Performance Test (EPT) .The instrument was subjected to content validity by three experts which are senior lecturers, two from Department of Science Education and from Measurement and evaluation Faculty of Education Federal University Gusau., and the Reliability coefficient of 0.87 using Test-retest was obtained during the pilot study, The pretest and posttest was used for data collection, Descriptive statistics of mean was used to answer the research questions while standard deviation was adopted to a certain the homogeneity or other wise of the respondents performance scores. Inferential statistics of analysis of covariance (ANCOVA) was used to test the formulated hypotheses at 0.05 alpha level.
