Development of Modeling Skill by Model-Based Learning Management for 11th Grade Students

Abstract

This research aim to develop modeling skill by using model-based learning of 11th grade students to pass the criterion of 70 percent of the full score and the number of students who received the required score was 70 percent of all target group students. The research design was action research and conducted in this research which were 3 cycles. The target group of 11th grade students at Yangtaladwittayakarn School in the second semester of academic year 2021 under The Secondary Education Service Area Office Kalasin total 31 students. Research instrument included                              (1) The instrument used in the experiment was 1) 9 lesson plans on the subject of “circulatory system and lymphatic system” based on using model-based learning (2) The instrument used to reflect performance and assess skills were                1) modeling skill test, 2) modeling activity and 3) a student interview form. The data were analyzed by standard statistics that contain average, standard deviation and percentage.

The results showed that in the first cycle the average scores of modeling skills was 69.35 which account for 72.24 percent and there were 19 students who passed the modeling skill score of 70 percent which account for                           61.29 percent of all target students. In the second cycle the average scores of modeling skills was 75.00 which account for 78.13 percent and there were 27 students who passed the modeling skill score of 70 percent which account for                 87.10 percent of all target students and in the third cycle the average scores of modeling skills was 81.03 which account for 84.41 percent and there were 31 students who passed the modeling skill score of 70 percent which account for                 100.00 percent of all target students. When considering the score from 1) modeling skill test after instruction, the average scores were 31.26, 35.26 and 38.16, representing 65.12, 73.45 and 79.50 percent. 2) modeling activity, the averages scores were 38.10, 39.74 and 42.87, representing 79.37, 82.80 and 89.31 percent. The previous data illustrate the number of student and modeling skill score was increased after learned by using model-based learning.
