The effects of learning through collaborative STAD technique and demonstration method with simulation on the topic of Vernier Caliper for enhancing learning achievement and teamwork skills of first-year certificate of vocational education automotive program students
Abstract:
The purposes of this research were: 1) to compare the learning achievement of vocational certificate students before and after implementing the STAD (Student Teams Achievement Divisions) cooperative learning technique and a demonstration method with simulation program on the topic of Vernier Calipers, 2) to study the effectiveness index of this instructional approach, and 3) to investigate the group work skills of vocational certificate students towards learning through collaborative STAD technique and a demonstration method with simulation. The sample consisted of 30 first-year vocational certificate students majoring in Automotive Technology at Rayong Technical College, Rayong Province. Students were randomly selected by using cluster random sampling. The research instruments included: 1) 5 instructional lesson plans, 2) a learning achievement test, and 3) a group work skills assessment form. Data were analyzed using mean, standard deviation, effective index post-test mean scores, and t-test dependent sample statistics. The research findings revealed that: 1) the students learning achievement after the intervention was significantly higher than before, at the .05 level, 2) the effectiveness index of this instructional approach was 0.7007 or 70.07%, indicating a 70.07% improvement in learning, and 3) the overall group work skills of the students were at a good level (average = 2.64, SD = 0.49).
