Mathematical problem solving ability and learning achievement on the problems of addition, subtraction, multiplication, and division of grade 5 students using bar model techniques

Abstract

The objectives of this study were to: 1) study the ability to solve problems on the problems of addition, subtraction, multiplication, and division of grade 5 students using bar model techniques with a 70% threshold; 2) compare achievement before and after learning management using bar model techniques; and 3) investigate students' satisfaction with learning management. The sample group was 26 grade 5 students in the first semester of the academic year 2022 at Kud Sim Witthaya San School, Khao Wong District, Kalasin Province, obtained by cluster random sampling. The instruments consisted of five lesson plans on fractions, an achievement test, and a satisfaction questionnaire. The statistics used to analyze the data were percentage, mean, standard deviation, and the hypothesis was tested using t-test (Dependent Sample).

The study discovered that: 1) The ability to solve problems in addition, subtraction, multiplication, and division using bar model techniques was higher than the statistically significant threshold of 70% 2) The learning achievement of the students who were managed by bar model techniques after learning was higher than before learning at the statistical significance level of .05. 3) The students were at a high level with the learning management system based on bar model techniques.
