The Effectiveness of Know-Want-Learn (KWL) Strategy on Ghanaian Basic Five Pupils’ Achievements in Mathematics

The purpose of the study was to determine the effectiveness of Know-Want-Learn (KWL) strategy in basic five pupils’ achievement in finding perimeter and area of plane figures. The study was conducted using a quasi-experimental design. The whole research was conducted at Sogasco Basic School in the South Tungu District in the Volta Region of Ghana, and it covered about four-week period. The participants of the study were 81 pupils, divided into two groups, ensuring gender balance: one an experimental group (n = 41) and the other a control group (n = 40). Two achievement tests (pre-test and post-test) were used to collect data for the study. The validity and reliability of the test results were established by using Conbrach Alpha method. SPSS was used to analyze the data. The findings revealed that, at five percent significant level, there were statistically significant differences between the mean scores of the pupils in the experimental and the control groups, in favor of the experimental group in terms of higher performances in the post-test; hence the KWL strategy used in the teaching of mathematics was very effective and had a great positive impact on the pupils’ mathematics concept build-up and problem-solving abilities in the basic schools.
