Abstract

The Covid-19 outbreak has changed the learning system in Indonesia into distance learning, better known as online learning. In determining student learning outcomes on student learning satisfaction with distance learning during the Covid-19 pandemic, a study was carried out using the Simple Additive Weighting (SAW) method. This study aims to determine student learning outcomes during the Covid-19 pandemic. The type of research used in this research is applied research, in which this research is directed to obtain information that can be used to solve problems. The method used is Simple Additive Weighting (SAW) by comparing the results of the decision of the SAW method between the weighting based on the Fuzzy Logic method and the weighting based on the ROC method. The subjects involved in this study were 36 students of Vocational High School (SMK). Data collection in the study was carried out using direct observation, interviews, and questionnaires. The criteria contained in the questionnaire are factors that affect the process of student learning outcomes on learning satisfaction during the Covid-19 pandemic. The criteria used are device ownership, accessibility, ease of obtaining materials, method accuracy, monitoring ability, interactivity, and independent learning. From the seven criteria, the priority scale is determined. The results showed that the analysis of the search for weight scores using the Simple Additive Weighting (SAW) method using Fuzzy Logic and Simple Additive Weighting (SAW) using the Rank Order Centroid (ROC) method resulted in different sub-criteria weighting scores, so it can be said that the combination of SAW- ROC provides a more accurate and more selective selection of the number of students.

Abstract

The advancement of digital technology has driven a transformation in elementary education toward more interactive and collaborative learning aligned with 21st-century competencies. This study conducts a systematic literature review of publications from 2020 to 2025 to map the implementation of digital-based STEM in elementary schools, the learning models employed, the impacts on student outcomes, and the challenges encountered. Article searches were conducted in Google Scholar and the SINTA-indexed database, following the PRISMA 2020 guidelines, yielding 10 studies for thematic analysis. The review indicates the use of interactive e-modules, digital videos, learning applications, virtual laboratories, and educational robotics, which generally enhance learning outcomes, creativity, numeracy literacy, critical thinking, and computational thinking. Key challenges include limited infrastructure, teacher readiness, and inconsistent quality of digital media. The findings underscore the need for policy support, improved teacher competencies, and higher-quality digital learning resources to optimize the integration of digital-based STEM in elementary education.
