DEVELOPMENT OF MATHEMATICS LEARNING ACTIVITIES MODEL WITH CREATIVE THINKING TO PROMOTE SOLVING PROBLEM SKILLS IN VOLUME AND CAPACITY OF GRADE 6 STUDENTS

Abstract

The purposes of this study were as follows: 1. create the mathematics learning activity format about volume and capacity and determine its effectiveness according to the criteria
of 75/75; 2. compare mathematical problem-solving skills using the mathematics learning activity format about volume and capacity between pretest and posttest; 3.study the satisfaction of students who have used the mathematics learning activity format about volume and capacity. The sample group was 6th grade students at Tha-It Municipal School. The tools used in the study included lesson plan organizing mathematics learning activities about volume and capacity, problem solving skills test and satisfaction assessment form. Statistical data were analyzed using T-test dependent samples, mean and standard deviation.

          The research results found that 1) the format for mathematics learning activities in this research, the independent variable is the format for mathematics learning activities, which consists of 11 learning activity plans. Each plan consists of 1) Attention-grabbing step,
2) Situation understanding step, 3) Idea integration step, 4) Problem solving step, 5) Presentation step, and 6) Step to clarify conclusions. Efficiency of the mathematics learning activity format about volume and capacity that the researcher created was effective according to the standard = 74.89/76.17, which is in accordance with the specified criteria. 2) Problem solving skills posttest scores (15.13) were higher than pretest scores (9.77) with statistical significance at the level of .05. 3) Sixth grade primary school students were satisfied with the format of organizing mathematics learning activities. Regarding volume and capacity, they are at a high level
(𝑥̅ = 4.28, S.D. = 0.70).
