Developing Biology Learning Activities by Using Problems Base Learning to Improve the Ability to Think Connectedly of Grad 11th Students

Abstract

The purposes of this study were to: 1) to develop the efficiency of learning management activities using the problem as an effective basis according to the 70/70 criterion. 2) to compare the connective thinking ability of Mathayomsuksa 5 students or grade 11 students who received a problem-based learning management activity with the criteria of 70 percent 3) to compare the learning achievement after receiving the problem-based learning management activity on the subject of immune system and excretory system of Mathayomsuksa 5 students or grade 11 students with the criteria of 70 percent. The research sample consisted of 37 Mathayomsuksa 5 students or grade 11 students in                the 2^nd semester of 2021 academic year at Phadungnaree school, Muang district, Mahasarakham province. The research instrument included 1) 11 plans, 17 hours for learning activity by problem-based learning in topic of excretory system and immune system, 2)  32 items 4 multiple choice the connective ability test with discriminating power ranging 0.20 to 0.73, with difficulties ranging 0.49 to 0.79 and reliability of 0.93 and 3) 30 items 4 multiple choice the achievement test with discriminating power ranging 0.20 to 0.65, with difficulties ranging 0.44 to 0.80 and reliability of 0.96.                         The statistic used for analyzing data were percentage, mean, standard deviation and test the hypothesis using statistical t-test (One samples t-test). 

The results were as follows: 1) the learning activities based on problem-based learning Inquiry have all 7 step consist step 1: define and understand problem, step 2: identify the problem, step 3: analysis and hypothesis, step 4: create a purpose learning, step 5: research, step 6: synthetic, step 7: exhibit the learning activities based on problem-based learning Inquiry had an efficiency (E₁/E₂) of 72.56/71.17, 2) students who have been learning by using learning activities based on problem-based learning inquiry having connective ability higher than 70 percent statistically significant at the .05 level and 3) students who have been learning by using learning activities based on problem-based learning inquiry having achievement higher than 70 percent statistically significant at the .05 level.
