THE INFLUENCE OF IMPLEMENTING THE PROJECT BASED LEARNING MODEL ON PROBLEM SOLVING SKILLS OF VOCATIONAL STUDENTS

Abstract

Abstract

Future development can be supported by education, namely education that can overcome and solve problems related to education itself. Thus, the problem-based learning model is included in the independent learning curriculum implementation strategy. The problem-based learning model revolves around problems that are relevant to students. The teacher's job is to involve presenting the problem, asking questions, and encouraging exploration and discussion. The purpose of this research is to analyze the effect of using problem-based learning model on critical thinking skills of vocational students. The method used is quantitative research with a pre-experiment design, specifically a one group pretest-posttest design. The sample is class XI TPM 2 with 33 students. Data collection is in the form of a subjective question test (Essay) of 5 questions, which is given at pretest and posttest. Data analysis was carried out parametric test, N-Gain score using spss statistic 26 software. The findings indicate that the paired sample t-test test produces a the value (two-tailed) of 0.000 is under the significance level of 0.05 (5%). It can be stated that the use of problem-based learning model has a significant impact on critical thinking skills of vocational students. Furthermore, the outcomes of the n-gain score test obtained 57.9%, including the moderately effective category. This happens because the problem-based learning model can increase student participation and accustom students to analyze information, evaluate alternative solutions, and make evidence-based decisions.
