Use of ACE (Act, Compute, and Explore) Sim in the Performance of Grade 7 of Pablo S. Villafuerte National High School on Basic Operations of Fractions

Abstract

INTRODUCTION

The study was developed to realize the advocacy of the writer to help her students who encounter difficulty in some mathematical concepts especially in dealing with operations of fractions. The researcher finds it significant to make a study and provide intervention to solve this problem. Five series of SIM on Operations of Fractions were made to provide the necessary skills in operations of fractions. SIM 1 contained activities for finding the GCF and Equivalent Fractions, SIM 2 covering conversion of Improper to Proper Fractions and vice versa, SIM 3 was restricted to adding Similar and Dissimilar Fractions, SIM 4 was all about Subtraction of Similar and Dissimilar Fraction, and SIM 5 confined to Multiplication and Division of Fractions.

METHODS

The study was guided by the qualitative study using descriptive evaluative research design. A series of paper and pen tests were administered to measure the level of performance of 30 Grade 7 of Pablo S. Villafuerte National High School on basic operations of fractions. For the descriptive part, t-test was used to determine the significant difference between the pre and post-test. The level of confidence was set to 95% or 5% margin of error.

RESULTS

A pre-test was administered to the group and after that, they were given SIMs in replacement of the conventional way of instructions. SIM 1 was given for three days, SIM 2, 3, 4 and 5 consumed two days each. The group was pre-and post-tested. Furthermore, detailed data collection was conducted for statistical analyses. After using the SIMs, post-test was given to the respondents. The t-value of 19.302 and t-the tabulated value of 1.699 is an indication of the significant difference between the scores of the participants from post-test against-test. This shows that the use of SIMs is an effective way of improving the achievement of the students in their Mathematics subject especially in operations of the fraction.

DISCUSSIONS

The study shows that there is a significant difference in the performance of 30 respondents after giving the SIMs. A big difference of 8.57 from the pre-test result of 7.30 to 15.87 was calculated after giving the intervention. The study recommends teachers to develop and use SIM as an intervention and remediation tool to improve the academic performances of students with difficulty in other subjects and also for enhancement for those students who are in the average type. It also encourages the administrators to provide training on the importance of developing SIM to the teachers.
