Development of Learning Management Model on Constructivist Theory with DLIT Media to Promote Problem-Solving Ability in Mathematics on Probability for Mathayomsuksa 5 Students

Abstract

This research has the objectives of: 1) To develop constructivist theoretical learning activities in conjunction with effective DLIT media according to the 75/75 criteria. 2) To find the learning activity effectiveness index 3) To compare academic achievement with a 75 percent threshold. 4) To compare problem solving skills with a 75 percent threshold. 5) To study the permanence of organizing learning activities. The samples in the research were 37 students in the , Bueng Malu wittaya School, Kantralak District, Sisaket Province, Semester 2, 2021, 1 classroom, including 37 students, which were obtained by cluster random sampling. The findings appeared as follows: 1) Constructivist theoretical learning activities in conjunction with DLIT media that promoted mathematical problem solving skills, effective ( E₁ / E₂ ) equal to 82.29/80.90, 2) The effectiveness index of posture learning activities with 0.6166, representing 61.66 percent, 3) achieved mathematical achievement, statistically significantly above the 75 percent threshold at .05 percent.,4) Have mathematical problem solving skills, statistically significantly above the 75 percent threshold at .05 ,5) after taking the post-study test. The average score was 24.27 points, then spaced out for 14 days and tested, with an average score of 23.95, which is not different.
