Abstract

This research analyzes the usefulness of cooperative learning, specifically deploying kalino cards, in boosting multiplication memorization skills among third-grade pupils in an elementary school context. The study employs an iterative strategy, implementing two cycles of intervention with continual refinement based on reflective observations and feedback. Traditional teaching techniques, characterized by lectures and restricted interactive media, exhibited inadequacies in supporting successful multiplication memorization, as evidenced by pre-test results. The inclusion of cooperative learning, integrating kalino cards, resulted in a considerable improvement in post-test scores. The iterative design stressed the necessity of constant reflection, resolving difficulties identified in the first cycle and associating favorably with improved outcomes in the second cycle. Qualitative findings from interviews indicated significant relationships between cooperative learning and increased student involvement and motivation. The usage of score sheets for evaluation also linked positively with student motivation, underscoring the relevance of effective instructional medium. In conclusion, this research demonstrates that cooperative learning with kalino cards holds significant potential for enhancing multiplication memorization skills among elementary school students, contributing valuable insights for educators seeking innovative and collaborative instructional methods.

Abstract

This research intends to assess the deployment of active game approaches in social studies learning in class V and its impact on student actions. The research was carried out through a classroom action research approach with two cycles, involving Class V pupils consisting of 24 students. Data was acquired through observation of student activities, analysis of daily test outcomes, and teacher feedback. The results of the investigation demonstrate that the deployment of active gaming approaches offers a positive contribution to student activities. In cycle I, improvements were noted although there were still impediments such as student activity which was not yet optimal. Through reflection in cycle I, changes and adjustments were made in cycle II, which resulted in more significant improvements. The problems experienced, such as low student involvement and a shortage of social studies textbooks, can be solved with help from the school and curricular revisions. Nevertheless, this research presents a good image of the potential of active game methods in improving student engagement and activity in social studies learning. The outcomes of this research can be a reference for teachers and connected parties in establishing creative and responsive learning approaches. Education that is centered towards active student participation can build an exciting and effective learning environment.

Abstract

This research analyzes the impact of adopting the Numbered Head Together (NHT) approach, paired with colored bead medium, on the comprehension of integer arithmetic among fourth-grade pupils. The study occurs in two cycles, adopting a comprehensive approach that incorporates planning, action, observation, and reflection. The research intends to evaluate the effectiveness of this new teaching style in increasing student engagement, collaboration, and academic success. The initial observations suggest a common dependence on traditional teaching approaches in mathematics education, resulting in decreased student engagement and poor academic performance. The intervention teaches the NHT technique, emphasizing cooperative learning, and using colorful bead medium to address problems related with integer arithmetic comprehension. The physical and visible aspect of the media attempts to adapt to varied learning styles and boost the accessibility of abstract mathematical concepts. In conclusion, the study recommends for a radical shift in mathematics education, asking educators to adopt student-centric, cooperative learning techniques, and inventive teaching tools. The favorable outcomes seen in this research underline the potential for such novel techniques to increase academic achievement and contribute to overall student development. This research serves as a call to action for educators to adapt and innovate in response to growing educational requirements.

Abstract

This action research intends to evaluate the impact of utilizing audio media in the teaching of Pancasila and Citizenship Education (PPKn) on students' learning outcomes. The study involved 30 students and applied a Classroom Action Research (CAR) approach to examine the effectiveness of integrating audio material in the instructional process. The data demonstrate a considerable improvement in individual and classical learning accomplishment during the second cycle. Individual proficiency grew from 15 to 18 students, while the classical proficiency rate rose from 75% to 90%. The average learning outcomes also showed a considerable improvement, with the average score climbing from 60.135 in the first cycle to 77.4 in the second cycle. This resulted in an overall improvement of 28.61% between the two periods. The research underlines the positive influence of audio media on boosting students' learning and accomplishment in PPKn. The study reveals that audio media can be a valuable tool in overcoming the obstacles experienced in teaching this subject, delivering a more interesting and effective learning experience for students. However, it is necessary to understand the study's limitations, such as the relatively small sample size and the focus on a single patient. Future study with bigger and more diverse samples could provide a more comprehensive knowledge of the broader applicability of audio media in educational contexts. In conclusion, the use of audio media in PPKn instruction constitutes a positive step toward increasing student learning outcomes. This research contributes to the educational literature and creates options for further inquiries into the incorporation of technology in learning contexts
