Abstract

This study aims to develop an E-LKPD based on a scientific approach at MAN 2 Model Medan. The results of this study are in the form of an Electronic Student Worksheet (E-LKPD). Data collection using validation questionnaires, practical questionnaires, student activity sheets, and student response questionnaires to E-LKPD based on a scientific approach. The trial of the E-LKPD was carried out face-to-face in Class X-4 at the MAN 2 Model school. The results of this development research are an E-LKPD based on a scientific approach for students of MAN 2 Model Medan showing that: (1) The E-LKPD developed is stated to be valid based on the assessment of experts and math teachers with an average validity rating of 84.23% with a score "Valid", (2) E-LKPD based on a scientific approach was declared practical based on an assessment from a mathematics teacher with a proportion of 81.73% and an assessment from students X-4 MAN 2 Model with a proportion of 92.8%, (3) E- LKPD based on a scientific approach has been declared effective based on an assessment from the student response questionnaire with a score of 84% and an assessment from the student activity observation sheet with a value of 88.15 and categorized as very positive. From the results of the analysis above, it can be interpreted that the E-LKPD based on the scientific approach of the Medan Model MAN 2 students is valid, practical, and effective in using the E-LKPD in schools.

Abstract

The research carried out in this article is a descriptive type of research to know the level of reasoning ability and analysis of the initial capacity in solving math problems of students in SDS Prestige Bilingual School on Minimum Competency Assessment and Non-Minimum Competency Assessment PISA like math-based questions. The subjects in this study were third-grade students of SDS Prestige Bilingual School for the 2021/2022 academic year, with a total of 14 students. The data collection method used in this study was to first distribute pretest questions to students with 60 minutes of processing time and continue with interviews. Interviews are intended to dig for more profound information about how students solve the given problems. The results of the pretest and interviews will be used as the primary data in answering the research problems. Based on the results of the research that has been carried out, it is obtained data that the research findings show students' initial reasoning abilities in general, students can solve the questions in the problem. In solving the questions given, some students tended to do trial and error, while the rest answered with good performance with answers that matched expectations. Keywords: Initial understanding, PISA, Reasoning ability, Minimum Competency Assessment.
