Abstract

Mathematics learning in elementary school plays an important role in developing students' logical and systematic thinking skills. However, initial observations in Grade II at SD Negeri 1 Mutihan showed conventional, teacher-centered learning, causing difficulties with whole-number concepts and simple data presentation, with a pre-cycle average score of 66.78 and 47.8% classical completeness. This study aimed to describe the implementation of a deep learning approach based on meaningful, joyful, and mindful learning activities and to improve the mathematics learning outcomes of Grade II students at SD Negeri 1 Mutihan. The study used the Kemmis and McTaggart Classroom Action Research model across three cycles in April 2026, involving 23 second-grade students. Data were collected through formative and summative tests, questionnaires, and documentation, then analyzed descriptively and supported by Normalized Gain (N-Gain) analysis. Results showed the average score rose from 66.78 (pre-cycle) to 82.17 (Cycle I, 82.6% completeness), 84.04 (Cycle II, 87.0%), and 86.65 (Cycle III, 100%). N-Gain analysis showed moderate improvement across all indicators: reading-writing numbers and place value (0.46), comparing numbers (0.52), and presenting data (0.60), with an overall N-Gain of 0.60 (moderate). The deep learning approach based on meaningful, joyful, and mindful activities was thus effective in improving students' mathematics learning outcomes.
