The Development of Problem Solving Skills and Learning Achievement by Problem-Based Learning Combined with KWL Technique for the 1st-Year Vocational Certificate Students

Abstract

          This research is aimed to 1) study the problem solving skills by using problem-based learning combined with KWL technique with the 70 percent criterion of the post-learning score, and 2) study the learning achievement by using problem-based learning combined with KWL technique with the 70 percent criterion of the post-learning score. The research sample consisted of 18 1^st-year vocational certificate students of the Northeastern College of Technology who were studying in the first semester of the 2024 academic year, selected by cluster random sampling. The research instruments were: 1) 6 lesson plans, 12 hours using problem-based learning combined with KWL technique; 2) 6 items of subjective problem-solving skill test; 3) 30-item, with 4 multiple-choice for learning achievement test. The data analysis was calculated with the basic statistics, covering mean, standard deviation and percentage.
          The research found that:
          1. Problem solving skills with problem-based learning combined with KWL technique for 1^st-year vocational certificate students had an average score of 83.22, or 86.96 percent of the full score, and 16 students passed the criteria, or 88.88 percent of the total number of students, which was higher than the specified criteria.
          2. Learning achievement with problem-based learning combined with KWL technique for 1^st-year vocational certificate students had an average score of 22.72, or 84.58 percent, and 16 students passed the criteria, or 88.88 percent of the total number of students, which was higher than the specified criteria.
