SYNTHESIS OF RESEARCH ON MATHEMATICAL PROBLEM SOLVING FOR LOWER SECONDARY SCHOOL STUDENTS BETWEEN 2014-2024

Abstract

          This research aimed to: 1) study the characteristics of research on mathematics problem solving for lower secondary school students; 2) assess the quality of research on mathematics problem solving for lower secondary school students; and 3) compare the influence magnitude of mathematics problem solving for lower secondary school students. The research instruments consisted of: 1) a research quality assessment form; and 2) a research summary form. Fifty studies were synthesized from 13 institutions, spanning the years 2014-2024. Glass's method was used to analyze the influence magnitude. Data were analyzed using descriptive statistics and one-way analysis of variance (ANOVA). The results of the research revealed that:

1. Research on mathematics problem solving for lower secondary school students The majority of research published in 2021 (14%) was Chulalongkorn University, the institution producing the most research (22%). Research from the Curriculum and Instruction disciplines produced the most research (48%), with the highest proportion of research being conducted in Mathayom 1 (38.60%).
2. The results of the quality assessment of the 50 research studies used in the synthesis of these studies were assessed as good overall, with a mean () of 3.10 and a standard deviation () of 0.48. Of these, 34 studies (68%) were assessed as good quality, and 16 studies (32%) were assessed as very good quality.
3. Research characteristics that influenced the magnitude of the effects of mathematics problem solving on lower secondary school students varied across four variables: population level or sample size, research design, mathematics problem solving, and learning content studied, all of which were statistically significant at the .05 level.
