Abstract

This study aimed to describe the implementation of the STEM SMART MART-based Problem Based Learning (PBL) model in improving the mathematics learning outcomes of fourth-grade students on whole numbers at SDN Putat Gede I/94 Surabaya. This study employed Classroom Action Research (CAR) based on the Kemmis and McTaggart model and was conducted in two cycles, with each cycle consisting of planning, action, observation, and reflection. The participants were 28 fourth-grade students. Data were collected through observation, tests, and documentation and were analyzed using qualitative and quantitative techniques. The results showed that the implementation of the STEM SMART MART-based PBL model improved students' learning outcomes. The average score increased from 63.92 in the pre-cycle to 76.60 in Cycle I and 83.03 in Cycle II. The percentage of learning mastery increased from 32% in the pre-cycle to 57% in Cycle I and 89% in Cycle II. Classroom observations also showed students' involvement in discussions, expressing opinions, solving problems, and participating in the SMART MART simulation. Therefore, the implementation of the STEM SMART MART-based PBL model improved students' learning outcomes and provided a more active and contextual learning experience in whole-number learning.
