A A DEVELOPMENT OF MATHEMATICS SKILL DRILLS ON SITUATION PROBLEMS IN THE LINE OF POLYA AND BAR MODEL ON TOPIC “POSITIVE MINUS MULTIPLY AND DIVIDE” FOR PRATHOMSUKSA 4 STUDENTS

Abstract

The objectives of this research are 1) to create and find the effectiveness of the math problem solving skill exercises. Based on the concept of Polya and bar model drawing techniques on addition, subtraction, multiplication and division. Mathematics subject group for grade 4 students according to the criteria 75/75 2) to compare the mathematics learning achievement before and after school 3) to study the students' satisfaction towards using the math problem solving skill exercises. The sample group was Grade 4 students at Ban Rahul School under the Office of Phetchabun Primary Education Area 3, the second semester of the academic year 2021, consisted of 30 people. It is a research and development model with 4 key components: 1) Study the basic information for the development of the Bar Model learning management model together with the concept of learning the ability to solve mathematical problems. 2) The creation of the Bar Model learning management model together with the learning ability in solving math problems 3) a study of the results of using the Bar Model learning management model together with the concept of learning ability to solve mathematical problems; and 4) a study of the students' satisfaction with the Bar Model learning management model. together with the concept of learning the ability to solve math problems. Use the research plan One Group Pretest – Posttest Design Research Tools Including exercises for solving math problems Based on the concept of Polya and bar model drawing techniques on addition, subtraction, multiplication and division. Mathematics subject group for 4th grade students, 4 subjects. achievement test Questionnaire on the satisfaction of learners towards learning with the formula-based skills practice questionnaire the statistics used in the data analysis were mean, standard deviation and Dependent t-test.

The results showed that

1. Math Problem Solving Skills Practice Form Based on Polya's concept and bar model drawing technique on addition, subtraction, multiplication and division, there are 4 topics for 4th grade students. The skill training process is based on Polya's concept and bar model drawing technique. It consists of 4 steps: (1) understanding the problem, (2) planning by using bar model drawing, (3) showing how to do it, (4) checking. The results of consideration of suitability found that the suitability of various components of the skill training was at a high level. and when it comes to efficiency found to be effective 77.45/76.83
2. The learning achievement of students who took the math problem solving skill exercises based on the concept of Polya and bar model drawing techniques on addition, subtraction, multiplication and division for grade 4 students after higher education. statistically significant at the .01 level
3. The students were satisfied with the learning with the math problem solving skill exercises based on the concept of Polya and the bar model drawing technique on addition, subtraction, multiplication and division for grade 4 students overall. to a large extent.
