Abstract

Low mathematics learning outcomes regarding the topic of angles were identified among fifth-grade students at SDN 01 Taman Kota Madiun. Pre-test results showed that only 7 out of 28 students (25%) met the Minimum Mastery Criteria (KKM) of 70, with an average score of 56.8. This study aimed to describe the implementation of the Contextual Teaching and Learning (CTL) model supported by interactive digital media and to determine its impact on mathematics learning outcomes concerning angles. The study employed the Classroom Action Research (CAR) method based on the Kemmis and McTaggart model, conducted over two cycles with 28 fifth-grade students as subjects. Data were collected through learning outcome tests, observation, and documentation, and subsequently analyzed using both quantitative and qualitative descriptive methods. The results indicate that implementing the CTL model supported by interactive digital media successfully improved students' learning outcomes. The class average score rose from 56.8 in the pre-cycle stage to 60.71 in Cycle I and 68.39 in Cycle II. The percentage of students achieving mastery also increased from 25% in the pre-cycle stage to 39.3% in Cycle I and 57.1% in Cycle II. Thus, the CTL model supported by interactive digital media serves as an effective instructional alternative for improving mathematics learning outcomes regarding angles in elementary schools.

Abstract

Learning Indonesian language, particularly imperative sentences, requires students to understand the characteristics and use of sentences in meaningful and contextual situations. However, the learning process in fifth grade at SDN 01 Taman Kota Madiun showed that students' learning outcomes on imperative sentences were still low, with many students unable to achieve the Minimum Mastery Criterion (MMC) of 75. This study aimed to improve the learning outcomes of fifth-grade students on the topic of imperative sentences through the implementation of the Problem-Based Learning (PBL) model assisted by digital comic media. The study was motivated by the low learning outcomes of students, as indicated by the large number who had not achieved the Minimum Mastery Criterion (MMC) of 75. This research employed a Classroom Action Research (CAR) design based on the Kemmis and McTaggart model, conducted in two cycles consisting of planning, implementation, observation, and reflection. The participants were 28 fifth-grade students at SDN 01 Taman Kota Madiun. Data were collected through learning achievement tests, observations, and documentation, and were analyzed using descriptive quantitative methods. The findings revealed a consistent improvement in students' learning outcomes across the research cycles. In the pre-cycle, 10 students (35.71%) achieved mastery with an average score of 60.71. After implementing the PBL model assisted by digital comic media in Cycle I, the number of students achieving mastery increased to 15 (53.57%) with an average score of 72.14. In Cycle II, learning mastery significantly improved to 23 students (82.14%) with an average score of 85.11. These findings indicate that the implementation of the PBL model assisted by digital comic media effectively improved students' learning outcomes. The novelty of this study lies in the integration of digital comics as contextual problem triggers that encourage students' active engagement in problem-solving activities during Indonesian language learning in elementary school, while also contributing to the development of innovative digital media-based learning.
