Abstract

Problem-solving ability is important for students to possess because life is inseparable from problems. However, in reality, students' problem-solving ability, especially in mathematics learning, remains relatively low, including in the Three Variable Linear Equation System (SPLTV) material. This study aims to validate the problem-based learning student worksheet, assisted by liveworksheets, for the SPLTV material as an alternative teaching material to improve students' mathematical problem-solving ability. The research method used a Development Study research design, involving four material experts and two media experts in the validation process. The research instrument used questionnaires for validation and a one-to-one interview instrument with three grade X MA students. Data analysis was carried out using descriptive statistical techniques to calculate the average percentage of the validation results. The validation results showed that the worksheet prototype was categorized as very valid with a score of 86.14%, and the learning media was categorized as very valid with a validity score of 91.67%. The interview results with three students indicated that the worksheet was feasible and practical to use. Based on the research results, the problem-based learning worksheet, assisted by Liveworksheets, met the validity standards; therefore, it is feasible to test after revisions based on the validators' suggestions.

Abstract

Mathematics learning in elementary schools still tends to be dominated by conventional approaches, so it is not optimal in developing students' critical thinking skills and digital literacy, especially in the material of measurement data. This study aims to develop and test the effectiveness of the Project Based Learning (PjBL) model assisted by the Canva application in improving critical thinking skills and digital literacy of fifth-grade elementary school students. The study used a Research and Development (R&D) approach by adapting the simplified stages of Borg and Gall, including needs analysis, planning, product development, expert validation, revision, limited trials, and extensive trials. The subjects of the study were fifth-grade students in an elementary school in Purwakarta Regency. Data were collected through validation questionnaires, pretest-posttest tests, digital literacy observations, and interviews. The results showed that the Canva-assisted PjBL model was in the very feasible category based on expert assessments. The application of this model was proven to be able to significantly improve students' critical thinking skills with a medium N-gain value and improve students' digital literacy in all aspects with a very good category. Thus, the Canva-assisted PjBL model is effectively used as an alternative to innovative and contextual Mathematics learning in elementary schools.

Abstract

Student Worksheets (LKPD) are teaching materials that help teachers deliver content to students. With LKPD, students find it easier to understand the material and become more motivated in the learning process. However, in practice, teachers are accustomed to using LKPDs purchased from book sales representatives, which often fail to present contextual problems as the starting point of the learning process. This study aims to produce valid teaching materials in the form of LKPD using the Realistic Mathematics Education (RME) approach on multiplication material for elementary school students. The research follows a design research method of the  development studies type. This study was limited to prototype 2, which underwenta formal review by three experts:  two senior teachers as subject matter experts and one lecturer as an education expert. using an expert validation instrument. The data collection technique used was qualitative data obtained from observations and interviews. The results show that the developed LKPD is very valid. It achieved an average validity score of 90%, placing it on the Very valid catagory. these findings contribute to the field of mathematics education by providing a proven, RME-based framework for LKPD design that bridges the gap between abstract multiplication  concepts and real-world application, offering apractical alternative to  commercial worksheets.
