Abstract

The aim of the research is to develop teaching materials assisted by media construct 2 software that are practical and appropriate for use in the learning process. The research method used is Research and Development (R&D) using the ADDIE model. The research was conducted at SMPN 3 Rancabali  with 12 class VIII students at Rancabali 3 Middle School for limited trials and 9 students at SMPN 2 Rancabali and 9 students at SMPN 1 Rancabali Public for a wider trial and 27 VIII C class students as an experimental class and 27 class VIII A students as the control class for product trials. The validators consist of ICT experts, subject matter experts and teachers. The data collection technique was in the form of a response questionnaire from students and teachers. The research results of the products developed were in accordance with the ADDIE research method with product feasibility categories based on ICT expert validation of 81.25%, material experts 85% and teachers 88% are all included in the very decent category. Products that have been validated are then tested on students through limited trials, wider trials and product trials and students are given practicality questionnaires with a final average result of 83.56% included in the very practical category. Based on the validation results of ICT experts, material experts and student and teacher responses, it was concluded that the teaching materials assisted by the media construct 2 software are valid and appropriate for use in learning. For further research, the researcher hopes to be able to develop teaching materials better according to the suggestions from the respondents.

Abstract

This study aimed to develop a Canva-assisted Student Worksheet based on the Realistic Mathematics Education approach on the topic of Two-Variable Linear Equation Systems (SPLDV) for Grade VIII students of SMPN 1 Cisarua, West Bandung Regency. This study employed a Research and Development (R&D) approach using the Borg and Gall development model. The research instruments consisted of expert validation sheets, student response questionnaires, readability sheets, and learning achievement tests. Data were analyzed using descriptive quantitative techniques to determine the validity, practicality, and effectiveness of the developed product. The validation results showed that the developed LKPD obtained a validity score of 83.75%, indicating that the product was valid and suitable for use in mathematics learning. The practicality test showed a score of 89.30%, categorized as very practical, indicating that students responded positively to the developed LKPD. Therefore, the Canva-assisted LKPD based on the RME approach is feasible to support mathematics learning on the topic of Two-Variable Linear Equation Systems.

Abstract

Student worksheet (LKPD) is a teaching materials containing activities that guide students in understanding topic. However, several studies have shown that LKPD is simply practice questions and are not tailored to students' needs. This study aims to design and test the effectiveness of a student-based LKPD.discovery learning assisted by wayground in improving mathematical connection skills and learning independence of junior high school students. This research is a Research and Development (R&D) with the Borg & Gall model, which consists of preliminary studies, planning and drafting products, expert validation, limited trials, extensive trials and product tests. The subjects of the study were 10 students of class IXA for limited tests and 32 students of class IXB for extensive tests and the subjects of product tests were 32 students of class VIIID for the experimental class and 32 students of class VIIIE for the control class in one of the public junior high schools in Bandung Regency. The research instruments include: Mathematical Connection Test, Learning Independence Scale, LKPD Validation Scale and Learning Assessment Response Scale. The results of the study show feasibility with several criteria: Validity obtained from the results of validation by material experts is 89% and media experts 90%, both in the very valid category. Practicality of 83% obtained from the results of student responses is in the very practical category and Effectiveness is obtained from the results of the Ngain analysis 60%, is in the effective category. Thus, LKPD based on discovery learning assisted by wayground effectively improves students' mathematical connection skills and learning independence.
