The Research and Development of Science Learning Management Model by Applying Mathematical Principles to Develop Computational Skill for Matthayomsuksa 2 Students.

The study aims 1) to study the problem conditions and guidelines for the development of an additional science learning management model to develop computational skills for Mathayomsuksa 2 students, 2) Develop and investigate the efficiency of organizing additional science learning activities to develop computational skills Mathayomsuksa 2, 3) to examine the planning science learning activities, and 4) to assess student satisfaction. The participants in this research were science teachers and 119 Mathayomsuksa 2 students in Nong Khai municipal schools. The research tools were 1) an interview form on problem conditions and guidelines for developing science learning activities to develop computational skills of Mathayomsuksa 2 students 2) 3 Lesson plans of science learning activity plan to develop numeracy skills Mathayomsuksa 2 students with the results of suitability assessment at the highest level with an average ( = 4.70, S.D. = 0.46) 3) Achievement Measurement, 30 items with a difficulty ranging from 0.43– 0.70, the discrimination power ranged from 0.40 to 1.00, and the confidence was 0.92. 4) Calculation Skills Scale, 25 items and 5) 15 items of Satisfaction Assessment. Statistics used for data analysis were percentage, mean, and standard deviation. and independent sample t-test.

The Research Result:

  1. Mathayomsuksa 2 students had learning achievement problems on beam, speed and speed of objects. The force that is exerted at an angle to the motion of an object from finding work from the area under the graph and friction.
  2. The problem-solving science learning activity was the integration of the teaching model by applying the A2R T2S mathematics principles to develop computational skills for Mathayomsuksa 2 students, acquired 3 Lesson plans of science learning activities were planned by applying mathematical principles A2R T2S to develop numeracy skills.
  3. Lesson Plans for additional science learning activities by applying mathematical principles to develop computational skills for Mathayomsuksa 2 students the efficiency (E1/E2) was 85.67/87.22 and the effectiveness index was 0.7762, with students having academic achievement indicating learners had increased learning progress in 77.62 percent and After learning, the learners have calculation skills was higher than before learning at statistical significance at the .05 level.

4. Mathayomsuksa 2 students were more satisfied with the additional science learning activities by applying mathematical principles to develop their numeracy skills at the highest level ( = 4.58, S.D. = 0.50).
