Abstract

This research is motivated by the low mathematics learning outcomes of students. This research aims to improve mathematics learning outcomes using the Teaching at the Right Level (TaRL) approach with the Problem-Based Learning model. The TaRL approach is a teaching method based on students' ability levels. The main subjects of this research are cube and rectangular prism in cycle 1, prism in cycle 2, and pyramid in cycle 3. The research was conducted from March to May 2024 in class VIII A of SMP Negeri 1 Mataram. The type of research is Classroom Action Research with three cycles. Each cycle consisted of planning, implementation, observation, evaluation, and reflection. The data collection techniques in this research used observation activities and learning outcome tests. The results of this research showed an improvement in mastery learning outcome in each cycle, with mastery learning in Cycle I at 55.882%, Cycle II at 70.588%, and Cycle III at 85.294%. This indicates that the TaRL approach can be used to improve student learning outcomes.

Abstract

This research aims to improve the learning outcomes of eighth-grade students in class VIII-H by implementing a cooperative learning model integrated with technology. This is a classroom action research that conducted in 3 cycles, focusing on improving student learning outcomes. The data collection techniques were obtained through tests and observations. The research findings indicate improved mathematics learning outcomes of VIII-H students at SMPN 1 Mataram following the implementation of a cooperative model with technology integration. The improvement is clear from the average scores recorded in each cycle. In the first cycle, the average score was 63.29, with a classical completeness rate of 44.74%. In the second cycle, the average score increased to 71.97, and the classical completeness rose to 73.68%. By the third cycle, the average score further improved to 84.61, resulting in a classical completeness of 84.21%. This improvement can be attributed to the student's success in completing the tests given during the learning process, which was enhanced by integrating technology in the form of PowerPoint, Geogebra, and Quizizz. The results of this study conclude that the cooperative model with technology integration can enhance students' mathematics learning outcomes

Abstract

This research is a Classroom Action Research (CAR) aimed at improving students’ mathematics learning outcomes on the topic of Lines and Angles through the implementation of the Discovery Learning model. The problem in this study is the low initial understanding of geometry concepts among students, particularly in the topic of lines and angles, which negatively affects their mathematics learning outcomes. This is evident from the pretest results, which showed that only 4 students (9.3%) achieved the Minimum Mastery Criteria (MMC). The research was conducted in two cycles using the Kemmis and McTaggart model, which includes the stages of planning, action, observation, and reflection. The research subjects consisted of 43 seventh-grade students from class VII E at SMPN 1 Mataram, who received treatment in the form of the Discovery Learning model implementation by the researcher. Data were collected through student activity observation sheets and learning outcome tests, which were then analyzed using descriptive quantitative and qualitative methods. In Cycle I, the learning focused on the types of angles (2 meetings), while in Cycle II, the focus was on the relationships between angles (3 meetings). The success criteria were determined based on students achieving MMC ≥ 75 and classical completeness ≥ 85%. The results showed an increase in classical completeness from 46.5% in Cycle I to 86% in Cycle II. Thus, the implementation of the Discovery Learning model proved effective in improving students' mathematics learning outcomes.

Abstract

This study was motivated by the previous learning process, which tended to be delivered uniformly without considering the varying ability levels of students. This approach resulted in low overall learning achievement at the class level. The objective of this study is to improve the mathematics learning outcomes of Grade VIII A students at SMPN 1 Mataram through the implementation of the Teaching at the Right Level (TaRL) approach, which is a learning strategy based on students’ ability levels. This research employs a Classroom Action Research (CAR) design, consisting of two cycles. Each cycle includes the stages of planning, implementation, observation, evaluation, and reflection. Data were collected through observation and learning outcome tests. The results of the study are as follows: (1) In the first cycle, the students' classical mastery reached 72.5%, with an average score of 73. These results did not meet the minimum success criterion for classical mastery, which is set at 85%. (2) In the second cycle, there was a significant improvement in learning outcomes, with classical mastery reaching 87.5% and an average score of 90. This indicates that the implementation of the Teaching at the Right Level (TaRL) approach can improve students' learning outcomes
