STUDY OF MATHEMATICS ACHIEVEMENT BY USING SUUGAKU METHOD OF PRIMARY 2 STUDENTS HATYAI CITY KINDERGARTEN (NA SUWANNAWONG SCHOOL)

Abstract

The research article aims to 1) compare the learning outcomes of second-grade elementary students in multiplication using the Japanese line method versus conventional multiplication learning methods, and 2) examine the satisfaction levels of a experimental group of second-grade elementary students towards the Japanese line method of multiplication learning. This research is experimental research. The population studied comprises second-grade elementary students in the first semester of the academic year 2024 from Hatyai city kindergarten (Na suwannawong school). The sample group consists of second-grade students selected through simple random sampling, totaling 2 classrooms, with each classroom representing mixed-ability learning. The research tools include lesson plans for Japanese line multiplication learning and conventional multiplication learning, post-learning outcome assessment tests with conformity indices ranging from 0.67 to 1.00, difficulty indices ranging from 0.31 to 0.75, discriminant power indices ranging from 0.33 to 0.79, and conformity indices between questions and objectives with confidence levels from 0.79. The satisfaction questionnaire for the experimental group students has a conformity index of 0.67 to 1.00. Statistical analysis utilized average values, standard deviations, and independent group mean comparisons. The research findings indicate that 1) students using the Japanese line multiplication learning method demonstrate significantly higher post-learning outcomes compared to those using conventional methods at a statistically significant level of .01, and 2) the satisfaction levels of the experimental group students towards the Japanese line multiplication learning method are exceptionally high (with a mean score of 4.73
