Towards Improving Senior High School Students’ Conceptual Understanding of System of Two Linear Equations

Abstract

This study basically focused on the use of algebraic tiles to improve Senior High School (SHS) students’ conceptual understanding of a system of two linear equations at St. Mary’s Seminary Senior High School, Lolobi in the Volta Region of Ghana. The test instrument used for the data collection was an achievement test with eight essay type questions, with an internal consistency reliability of 0.78. The simple random sampling technique was used to assign 70 SHS two students equally to experimental and control groups. The two groups were pre- and post-tested in the study. A paired-sample t-test was used to analyze the data. The results showed that even though there was some improvement in the posttest across the board (both control and experimental groups), there was a statistically significant improvement in the experimental group which received the intervention for four weeks using the algebraic tiles.
