The Results of Developing Science Process Skills of Grade 8 Students Through the 5E Inquiry-Based Learning Approach Using Simulated Situations in Private Schools, Mueang District, Ubon Ratchathani Province

Abstract

The objectives of this research were 1) to study the effectiveness of the learning management plan on the topic of Separation of Mixtures, Science Subject Group, Grade 8 Students, by 5E Inquiry Teaching with Simulation according to the 80/80 criteria, 2) to compare the science academic achievement before and after learning of Grade 8 students who were taught by 5E Inquiry Teaching with Simulation, 3) to compare the science process skills before and after learning of Grade 8 students who were taught by 5E Inquiry Teaching with Simulation, and 4) to study the satisfaction of Grade 8 students towards the learning management by 5E Inquiry Teaching with Simulation. The sample consisted of 30 Grade 8/1 students of St. Emilie School, Ubon Ratchathani Province, second semester of the academic year 2024, who were selected by cluster selection using the classroom as the random sampling unit. The research instruments consisted of 1) 6 lesson plans with an average appropriateness of 4.65, which is at the highest level, 2) a 30-item achievement test with a reliability of 0.89, 3) a 30-item science process skills test with a reliability of 0.92, and 4) a 15-item student satisfaction questionnaire. The statistics used for data analysis were percentage, mean, standard deviation and t-test. The research results showed that: 1.The lesson plans on Separating Mixtures, Science Subject Group, Grade 8 by using 5E Inquiry Teaching with Simulation had an efficiency of 86.88/87.44, 2. The students’ science achievement after learning was higher than before learning at a statistical significance level of .05, 3. The students’ science process skills after learning were higher than before learning at a statistical significance level of .05, and 4. The students had the highest overall satisfaction with the learning management.
