The Effect of Algebra Tiles in the Operations of Integers and Polynomials to the Academic Performance of Grade 7 Students

The study determined the effects of algebra tiles in the operations of integers and polynomials to the academic performance of Grade 7 students of Gil Montilla National High School- Camindangan Extension enrolled in the academic year 2023-2024. A standardized questionnaire based on the Enhanced Regional Unified Numeracy Test (ERUNT) of DepEd Region VI for the operations on integers and based on the self-learning modules published by the Schools Division of Pasig City for the operations of polynomials were used in gathering the data. There are 80 participants in determining the pre-test and post-test performance of the Grade 7 students. Out of 80 participants, 40 were assigned as control group. In the operations of integers, the pre-test mean is 20.20, while the post-test mean is 26.38. In the operations of polynomials, the pre-test mean is 2.40, while the post-test mean is 7.83. The results revealed that there was an increase in the performance of the control group. There are also 40 participants in the experimental group who took the pre-test and post-test in the operations of integers, the pre-test mean is 19.17, interpreted as nearly proficient, while post-test mean is 27.78, interpreted as nearly proficient. In the operations of polynomials, the pre-test mean is 2.37, interpreted as not proficient, while the post-test mean is 9.70, interpreted as low proficient. Thus, there is an increase in the performance of the experimental group in the operations of integers and polynomials. Using the Wilcoxon Signed Ranks Test at 0.05 level of significance in the operations of integers, the computed value is -5.518 and the p-value is <0.001. In the operations of polynomials, the computed value is -5.519 and the p-value is 0.001. Since the P value in both operations are less than 0.05 level of significance, the null hypothesis is rejected. This means that there is a significant difference between the pre-test and post-test performance of the experimental group in the operation of integers and polynomials. The result suggests that algebra tiles are effective in improving students’ performance in the operation of integers and polynomials. This implies that the class sessions and the use of algebra tiles has a significant effect to the performance of the Grade 7 students. Furthermore, there is no significant difference between the control and experimental group in the operations of integers and polynomials.
