The objective of this study is to develop learning activities for sixth-grade students centered around the topic of "Substances and Properties of Substances" with the intention of enhancing their problem-solving skills. The research was carried out in three distinct phases: Phase 1 involved reviewing guidelines for designing science learning activities aimed at improving problem-solving abilities. Phase 2 focused on the development of learning activities related to "Substances and Properties of Substances" with the goal of enhancing problem-solving skills among sixth-grade students. Phase 3 encompassed the testing of these learning activities with a group of 18 sixth-grade students from Ban Pho Song Hong Witthaya Community School during the second semester of the academic year 2022. Various research tools were employed, including an interview form, learning plans, a 30-items learning achievement test (with difficulty ranging from 0.43 to 0.67, discriminating power from 0.36 to 0.63, and reliability of 0.97), a problem-solving ability inventory consisting of 24 items (with difficulty ranging from 0.33 to 0.77, discriminating power ranging from 0.23 to 0.47, and reliability of 0.86), and a satisfaction questionnaire. Statistical methods such as mean, standard deviation, percentage, and dependent sample t-tests were used for data analysis. The research yielded the following outcomes:
1) The Science learning activities on “Substance and Properties of substance” to promote problem-solving abilities for sixth-grade students, there are 4 learning plans. The learning activities consisted of 6 steps: (1) problem determination, (2) problem understanding, (3) study and research, (4) knowledge synthesis, (5) summarizing and evaluating the answer, and (6) presentation and evaluate the work, which the appropriate is height level. 2) The sixth-grade students have learning achievement on “Substance and Properties of substance” after learning the activities are higher than before learning statistically significant at the .01 level. 3) The sixth-grade students have problem solving abilities on “Substance and Properties of substance” after learning the activities are higher than before statistically significant at the .01 level. 4) Students were satisfied with science learning activities at the highest level.
