Improving Performance in Adding and Subtracting Decimals and Mixed Decimals of Grade VI Pupils in Alcala ES through Strategic intervention Materials (SIM)

Abstract

INTRODUCTION

Several studies have been developed to address the causes of difficulty of understanding and underachievement in mathematics, yet nobody has done a particular study specifically on improving performance in adding and subtracting decimals and mixed decimals through Strategic Intervention Materials (SIM). Hence, this study aimed to improve performance in adding and subtracting decimals mainly of Grade VI Pupils in Alcala ES through SIM that makes this study unique. Mathematical skills being developed by this study were one of the skills in the K-12 curriculum. This SIM helped students gain confidence in solving numbers on their own.

METHODS

The descriptive-quantitative research method was employed in this study. The standardized weekly test result was recorded particularly the Mean Percentage Scores (MPS). Twenty (20) pupils of Grade VI Class (Turquoise & Topaz) who failed in the weekly test was considered as participants. SIM was crafted to remediate those difficulties reflected from the weekly test. The researcher described the result of the standardized weekly test using T-Test Analysis through Minitab. The performance of the learners in the pretest and post-test was analyzed for a significant difference.

RESULTS

There was a significant relationship between the performance of the pupils and the SIM that was introduced and implemented. The mean before the implementation was 0.85 and the mean after was 7.25 with a gain of 6.4. Using t-Test, utilizing .05 level of significance or probability and p-value of <0.001, it was revealed that the different levels of significance fall closer or less than .05 ï ¡. Thus, the Null Hypothesis is rejected and the Alternative Hypothesis is accepted.

DISCUSSIONS

The results revealed that there was a significant relationship between the performance of the pupils before and after the SIM was employed. It was visible that with the use of intervention material such as Strategic Intervention Material (SIM), the learning process in children's minds would be extended and difficulties in Mathematics would be lessened. Manipulative and colorful learning materials encourage pupils to continue and discover said learning material. The participants in this study were exclusively in Grade VI Level. It is recommended that future researchers may use similar intervention material to other grade levels.
