Learning Activity Management in According to the Problem-Based Learning for Enhancing Students’ Learning Achievements and Problem-Solving Skills toward Science

Abstract

The purposes of this research study were 1) to develop learning activity management with the Problem-based learning (PBL) instructional lesson plans with the efficiency (E₁/E₂) at the determining criteria as 80/80, 2) to compare students’ learning achievements of their post assessing test and the criteria of 80% and 3) to compare student’s problem-solving skills toward science of their post assessing test and the criteria of 80%. Research with a target size of 17 Prathomsuksa 6 from Ban Thamuang School of Selaphum Amphur Roi Et Province with the purposive sampling technique was selected. Research using 1) the 6-main instructional PBL method’s lesson plans to management of the activity-based learning with instrument was a 5-rating scale and indicated that of 4.74, 2) the 30-item learning achievement assessing test with IOC indicated between that 0.60-1.00, difficulty index 0.36-0.62, discrimination index 0.28-0.62, reliability that 0.81 and 3) the 20-item problem-solving skills toward science with instrument was a 5-rating scale and indicated that of 4.82, basic data analyzed with the average mean, standard deviation, percentage and Statistically significant t-test for one sample were analyzed, The results indicated that:

1.            The results have found that the efficiency of the processing performance and the performance results (E₁/E₂) of the PBL indicated that of 85.48/84.44, which was higher than standardized criteria of 80/80.
2.            Average mean score of learning achievements of their post - test was higher than 80% with the PBL instructional method were differentiated that evidence of statistically significant at the .01 level.
3.            Average mean score of problem-solving skills toward science of their post - test was higher than 80% with the PBL instructional method were differentiated that evidence of statistically significant at the .01 level.
