Assisting Basic Seven Pupils of Zogbeli Junior High School, Block A, Using Rectangular Array Model to Overcome Their Difficulty in Finding the Factors of Numbers

Abstract

This study aimed to investigate the effectiveness of using the Rectangular Array Model to assist pupils of Zogbeli Junior High School Block “A” in the Sagnarigu Municipality, Tamale in Ghana. The population of the study consisted of 90 pupils, and a simple random sampling technique was used to select 45 pupils as the sample. The results showed a significant improvement, with 88.89% of the pupils demonstrating the ability to find the factors of numbers. The statistical analyses were performed to assess the effectiveness of the intervention. The pre-test mean was calculated as 13.28, indicating a low level of performance, while the post-test mean was 37.7, indicating a substantial improvement. Furthermore, the standard deviation values were 9.86 for the pre-test and 9.95 for the post-test, suggesting consistent improvements across the sample. The eta square calculation indicated a value of 0.999, indicating excellent validity and reliability of the intervention. This high value suggests that the Rectangular Array Model was highly effective in assisting pupils in overcoming their difficulty in finding the factors of numbers. Overall, the findings of this study support the use of the Rectangular Array Model as an effective teaching tool for pupils experiencing difficulty with this mathematical skill. These results provide valuable insights for educators and curriculum developers seeking innovative approaches to enhance mathematics education in Ghana.
