Abstract

This study aims to improve mathematics learning outcomes in second-grade students at SDN No. 100615 Sigalangan in the topic of integer arithmetic operations using the RME Model. The methodology applied in this study is the Classroom Action Research (CAR) approach based on the Kemmis and McTaggart model which took place in two cycles, involving 19 students from second grade. The results of the study showed significant growth and overall achievement. The successful implementation of RME learning by teachers obtained an average score of 3.51 (Well Met), supported by very positive student responses with an average reaching 88.42%. The improvement in learning outcomes is seen from the surge in the percentage of classical completeness which increased from 52.63% (Cycle I - Poor) to 94.73% in Cycle II (Very Good Category), with an average post-test score increasing to 90.52. Therefore, the implementation of the RME Model has proven effective and successful in improving the mathematics learning outcomes of second- grade students at SDN No. 100615 Sigalangan.

Abstract

This study aims to resynthesize crucial concepts regarding measurement scales and sampling techniques to address methodological discrepancies that frequently occur in educational research. In the dynamics of educational management, the accuracy of the variable quantification process and the representativeness of the sample are the primary determinants of the validity of empirical findings and the accuracy of generalizations of research results. The method used in this article is a library research study with a qualitative-descriptive approach, which examines relevant scientific literature from the last five years. The results of the discussion indicate that the measurement scale is divided into four hierarchical levels: nominal, ordinal, interval, and ratio, where each level determines the data structure and the type of statistical analysis that can be applied. In addition, this article describes attitude measurement instruments such as the Likert Scale, Guttman Scale, Semantic Differential Scale, and Rating Scale. Regarding sampling techniques, the discussion is divided into probability sampling (simple random, systematic, stratified, and area) for statistical objectivity, and non-probability sampling (purposive, convenience, snowball, quota, and saturation) for in-depth phenomena in a specific population. This article is expected to be a reference for researchers in maintaining the integrity, validity, and credibility of research findings in the field of education.
