Abstract

This research aims to analyze: 1) the validity, practicality and effectiveness of the PBL e-module based on Batak Toba Culture (PBL BTC) which was developed to increase students' problem-solving abilities at SMP Negeri 1 Simanindo; 2) increasing students' problem-solving abilities through the developed e-module. This research is using the ADDIE. From the tested of class IX 2 was obtained: 1) the PBL BTC e-module have the criteria of being valid, effective, and practical; 2) Increased problem-solving abilities using the PBL BTC e-module as seen from the N-gain value is 0.506, it is in the "medium" category. This research recommendations might be made the E-Module with mathematical problem-solving tasks on the topic of congruency should be continued for future effectiveness evaluations.

Abstract

This study employed classroom action research with the aim of enhancing students' physics problem-solving skills using Problem-Based Learning (PBL) supported by student worksheets (Lembar Kerja Peserta Didik/LKPD). The research targeted 10th-grade high school students focusing on the topic of Measurement. The methodology followed a cycle comprising four stages: planning, action, observation, and reflection. At the end of each cycle, evaluations were conducted using a validated test instrument consisting of four essay questions. The success criterion was set at a minimum of 70% of students achieving a mastery level, defined by a score of at least 65. During the pre-cycle phase, before applying PBL, the initial test results revealed no students achieved mastery, with an average problem-solving score of 54.67. Subsequently, two cycles of PBL implementation were carried out. In the first cycle, 15 students reached the mastery criterion, representing 41.17% improvement in problem-solving skills, with an average score of 63.75. Building on this progress, the second cycle was implemented, resulting in 29 students achieving mastery. This represented 80.05% of the class, categorized as a moderate improvement, with an average problem-solving score of 70.05. These findings indicate a significant enhancement in students' physics problem-solving abilities through the integration of PBL and LKPD. This approach effectively facilitated active student engagement and critical thinking, demonstrating its potential as an impactful instructional strategy in high school physics education.

Abstract

This research develop a digital learning materials that implemented in Ambarita Village, situated near Lake Toba, Samosir Island, that has preserved its indigenous knowledge and traditional customs. The purpose of this study is to analyze the following: 1) the effectiveness, validity, and practicality of the PBL e-module based on Batak Toba Culture (PBL BTC), which was created to improve students' problem-solving skills at SMP Negeri 1 Simanindo; and 2) improving students' problem-solving skills through the developed e-module. The ADDIE is being used in this study. Two results were obtained from the class IX-2 test: 1) The PBL BTC e-module met the requirements of validity, effectiveness, and practicality; 2) Using the PBL BTC e-module improved problem-solving skills as demonstrated by the N-gain value of 0.506 and improved self-efficacy by the N-gain value 0.338 which places it in the "medium" category
