Abstract

This study aims to implement and evaluate the effectiveness of the Problem-Based Learning Model (PBL) in improving the learning outcomes of class X Office Management (MP) 1 students on the material of social interaction and dynamics at private vocational secondary schools 1 Jombang. The research method used is a quantitative approach with a pretest-posttest design. The research sample consisted of 34 students who were all used as respondents through saturated sampling techniques. The results of the study showed that there was a significant increase in student learning outcomes after the implementation of the PBL model. The average pretest score of students before problem-based learning was 73, while the average posttest score increased to 82. In addition, students' responses to this learning model were also very positive, with increased motivation and involvement in the learning process. Based on the results of the study, it can be concluded that the implementation of the PBL model is effective in improving student learning outcomes. Therefore, it is recommended that teachers apply this method more often to improve student activity and understanding. In addition, further research is recommended to consider the characteristics and needs of students so that learning can run more optimally.

Abstract

Teachers should be able to stimulate students' science process skills or be able to stimulate students' creativity. This study aims to develop a practical work guideline for Basic Electronics I based on Problem-Based Learning (PBL) designed to improve the science process skills of physics education students. This study uses a 4D development model, but is limited to the Develop stage, with a focus on a systematic planning process and the development of valid and practical teaching materials. The research data consists of expert validation and student responses regarding the practicality of the developed product. The instruments used were an expert validation sheet and a student response questionnaire, both using a Likert scale of 1–4. Data were analyzed quantitatively by calculating the average score and percentage, then broken down into levels of validity and practicality. The results showed that the practical guidelines were assessed as “very valid” by material experts (85%) and media experts (86%). Student responses to the practicality questionnaire also showed “very practical” with a score of 88.7% and a positive response of 81.3%. These findings indicate that the PBL-based Basic Electronics I practicum guidelines, which include Kirchhoff's Current Law, Ohm's Law, and voltage dividers, are valid and practical, making them suitable for use as alternative teaching materials to support practicum activities and optimize students' science process skills. Further researchers are advised to add learning outcome evaluation instruments to determine the direct impact of PBL-based practicum guidelines on students' conceptual mastery and critical thinking skills.
