Influence of Problem Based Learning and Problem Solving Learning Combined with Braistorming on the Vocational High School Students’ Learning Outcomes

Abstract

Based on the results of observations made in class X TKJ SMKN 2 Probolinggo, it shows the lack of courage of students in expressing opinions, students' skills in solving problems are less than optimal, and basic programming learning outcomes obtained by 69% of students below the KKM. The problem is the background of this research to determine the learning outcomes (Y) of basic programming because of the influence of the application of the problem-based learning model combined with brainstorming (X1) compared to problem solving learning combined with brainstorming (X2). The learning outcomes in question are knowledge learning outcomes (Y1) and skills learning outcomes (Y2). This study aims to: (1) reveal the significance of the difference in Y1 due to the effect of applying X1 compared to X2; (2) revealing the significance of the difference in Y2 due to the effect of applying X1 compared to X2. This study used a quasi-experimental research design with a pretest posttest design. The subjects of this study were class X TKJ 1 and class X TKJ 3 as. Class X TKJ 1 amounted to 34 students were given X1 treatment. Class X TKJ 3 totaling 32 were given X2 treatment. The results of hypothesis testing using t-test, show Y1 class X TKJ 1 compared to class X TKJ 3 obtained a significance number of 0.012, Y2 class X TKJ 1 compared to class X TKJ 3 obtained a significance number of 0.000. The conclusion from the research is that there is a significant difference between the results of learning basic programming because of the effect of applying the problem-based learning model combined with brainstorming compared to problem solving learning combined with brainstorming.
