Interaction effect of concept mapping strategy on pupils' achievement in vocabulary across school type in Makurdi Local Govt. Area, Benue State

Abstract

The study investigated interaction effect of concept mapping strategy on pupils' achievement in vocabulary across school type in Makurdi Local Government Area, Benue State-Nigeria.  It was guided by two research questions and two hypotheses. Quasi-experimental research design was adopted for the study. Proportionate stratified random sampling technique was used to sample 103 lower basic five pupils in four intact classes. Vocabulary Achievement Test (VAT) was used for data collection while lesson plans were used for treatment. Mean and standard deviation was used to analysed the data while Analysis of Covariance(ANCOVA) was used to test the two hypotheses at 0.05 level of significance. The findings of the study revealed that pupils in public schools performed better than pupils in the private schools in vocabulary achievement when taught using concept mapping strategy. The study also showed that the interaction effect of concept mapping strategy and school type was not statistically significant. The study recommended among others that English Language teachers in both public and private schools shold refrain from limiting themselves to the use of conventional stategy of teaching pupils vocabulary.
