DEVELOPMENT OF MATHEMATICAL ACHIEVEMENT IN FINDING PERIMETER AND AREA BY USING 5E INQUIRY-BASED LEARNING WITH MIXED MEDIA FOR GRADE 6 STUDENTS

Abstract

The objectives of this research were: 1) to determine the efficiency of lesson plans based on the 5E Inquiry-Based Learning cycle integrated with multimedia on the topic of "Perimeter and Area" for Grade 6 students, based on the 80/80 efficiency criteria; 2) to compare students' academic achievement before and after participating in the 5E Inquiry-Based Learning and multimedia-integrated lessons; 3) to compare students' mathematical problem-solving skills; and 4) to investigate students' satisfaction with the learning management.The sample group consisted of 34 Grade 6 students from Ban Phu Khao Kham School, under the Office of Amnat Charoen Primary Educational Service Area. The research instruments included: 12 lesson plans with an average quality score of 4.58, indicating the highest level of appropriateness; a 40-item analytical thinking test with an Item-Objective Congruence (IOC) index of 1.00 for all items; a 40-item academic achievement test with difficulty levels ranging from .31 to .75, discrimination power between .23 and .91, and a reliability coefficient of .80; and a 15-item satisfaction questionnaire with an IOC index of 1.00 for all items. Data were analyzed using mean (𝑥̅), standard deviation (S.D.), and t-test Dependent Samples.

Research Findings

1. The efficiency of the 5E Instructional Model combined with multimedia for learning "Perimeter and Area" was 90.44/91.99, which met the established 80/80 efficiency criteria.
2. The comparison of learning achievement using the 5E Instructional Model and multimedia for Grade 6 students revealed that the post-test scores were significantly higher than the pre-test scores at the .05 level, confirming the research hypothesis.
3. The comparison of mathematical problem-solving skills following the 5E Instructional Model and multimedia approach showed that post-test scores were significantly higher than pre-test scores at the .05 level, which was in accordance with the research hypothesis.
4. The study of student satisfaction towards the 5E Instructional Model and multimedia approach indicated an overall satisfaction at the highest level ((𝑥̅) = 4.58, S.D. = 0.66).
