The purposes of this research were to study students’ learning outcomes on combinatorics after being taught via a learning management based on constructivism theory and also to investigate students’ satisfaction levels toward the learning management. The participants recruited by a cluster random sampling technique were 40 Mathayomsuksa I students from Senangkhanikhom school in Senangkhanikhom district, Amnat Charoen, in the second semester of the 2018 academic year. We designed a constructivist learning management including six instructional plans for the topic of combinatorics. Each plan was divided into two periods with 50 minutes for each. The subjects were taught combinatorics through the six plans. The pupils, as well, were assigned to take 3 exams of students’ learning outcomes on combinatorics, and they were asked to complete questionnaires of students’ satisfactions after studying combinatorics via our created learning management at the end. Students’ responses on the exams and questionnaires were graded and collected as the data of this study.
The research findings revealed as follows: 1) After being taught the topic of combinatorics via our constructivist learning management, over 60% of the participants satisfied the set criteria, at the statistically significant .05 level. 2) The mean score of the subjects’ satisfaction toward the learning management was at the “high” level, overall.
