The Effect of Model-Eliciting Activities Using Manipulative in Mathematics to Mathematical Disposition and Problem Solving Performance of Grade 10 Students of Calamba City

Abstract

INTRODUCTION

Model-eliciting activities (MEAs) are activities that encourage students to invent and test models. They are posed as open-ended problems that are designed to challenge students to build models in order to solve complex, real-world problems. (Lesh, Hoover, Hole, Kelly, & Post, 2000, p. 597). This study aimed to increase the level of mathematical disposition and problem solving performance of grade 10 students of Calamba City.

METHODS

One hundred (100) students from heterogeneous group were divided into two but only one group was given treatment. Treat to internal validity were determine using the second group. In a control group, students were taught using conventional teaching strategies while the experimental group was taught through model-eliciting activities using manipulative. Applying mixed method, qualitative data was collected and evaluated using score card based on the given tasks daily.Following grounded theory, data was collected and interpreted using t-test independence and correlation analysis. Both experimental and control group were pre-tested and post-tested using the teacher-made test and the mathematical disposition test.

RESULTS

Findings revealed that there is a significant difference between the pre-test and post-test of grade 10 students during the fourth grading period of the school year 2016-2017. Likewise, there is a significant relationship between the result of the two test administered. It was found out that participants presented high level of mathematical disposition when it comes to problem solving performance after the treatment period. Having the value of r = 0.978 at 0.05 level of significance, it was then concluded that model-eliciting activities using manipulative help the students to increase their self-confidence, curiosity, flexibility, diligence and reflective in doing math.

DISCUSSIONS

Based on the result, it was recommended that Model-Eliciting Activities using manipulative should be implemented across grade level in the particular school used for the study before it was fully implemented across grade level within the Division of Calamba City. The strategy also used to implement the school to school partnership (SSP) program for it will helped the learners to improve their mathematical abilities. And lastly, it will be presented to School Learning Action Cell (SLAC) so that not only the researcher will benefit the study but also the teachers and administrator.
