Abstract

This research is based on the era of digital transformation and the Industrial Revolution 4.0, which demands education that is adaptive to technology and involves a contextual approach integrated with local wisdom. The problem in this research is the implementation of economic learning, which tends to rely on conventional learning models and underutilise students' critical thinking skills. This study aims to develop a learning model that combines the Deep Learning model, the Contextual Approach, and Tapanuli Local Wisdom that can teach students critical thinking skills. However, at this stage, the discussion focuses on the validity of the learning model product. To achieve the research objectives, the Plomp model was used, which involved the stages of Preliminary Investigation, Design, Realization/Contruction, Test, Evaluation and Revision, and product revision through product validation by five validators. The results of the study indicate the need for a learning model product that integrates deep learning, the Contextual Approach, and Tapanuli Local Wisdom. Furthermore, the model book design was found to be valid and suitable for use, with only minor revisions required. The research conducted provides a conclusion that the Deep Learning learning model, integrated with a contextual approach and local wisdom, is worthy of being tested to teach students' critical thinking skills in economics.

Abstract

The purpose of this study was to produce E-LKPD based on truth or dare game on trigonometry material of sine and cosine rules. This study used the ADDIE development model consisting of 5 phases, namely analysis, design, development, implementation and evaluation. However, research was conducted only the implementation phase. The subjects of this study were 27 students. Validity was obtained based on the validator's assessment. Practicality was obtained based on the results of observer observations of student activities. Effectiveness was obtained based on students' pretest and posttest scores. The results of the analysis of E-LKPD based on truth or dare game on trigonometry material of sine and cosine rules have a validity percentage of 87.91% with very valid criteria. The practicality of E-LKPD based on truth or dare game has a practicality percentage of 93.5%, with a very practical category. The effectiveness of E-LKPD based on truth or dare game is 81.134%, with very effective criteria. Conclusion of the research, the development of E-LKPD based on the truth or dare game was be valid, practical, and effective in applying trigonometry learning of the rules of sines and cosines for the eleventh grade students.

Abstract

Students pay less attention to the teacher during the learning process because students find it difficult to understand the learning material, especially in mathematics. The purpose of this study was to determine the effectiveness of the contextual learning model on students' mathematical problem-solving abilities on the material of two-variable linear equation systems in Class X of SMK Negeri 1 Angkola Timur. The type of research used by the researcher is quantitative research. In this study, the researcher used the True-Experienced Design design with the One Group Pretest and Posttest Design type. The population was all students of Class X at SMK Negeri 1 Angkola Timur consisting of 6 classes totaling 92 students. Based on the data analysis, the researcher drew conclusions based on the results of data collection, there was an effectiveness of the contextual learning model on the material of two-variable linear equation systems on students' mathematical problem-solving abilities. This is evidenced by the results of the paired sample test that has been conducted in the experimental class. It can be concluded that H0 in the experimental class is rejected and Ha is accepted because the sig value (2-tailed) in the experimental class is 0.00 less than 0.05. Furthermore, based on inferential statistics using the pair sample t-test, (SPSS version 27), the results show a significance value of less than 0.05 (0.000 < 0.05). This means that the constructivism learning model is effectively used for the mathematical problem solving abilities of class X students of SMK Negeri 1 Angkola Timur.
