Abstract

The aim of this study is to improve students' problem-solving abilities by using the Reciprocal Teaching instructional style. The study included 28 students from class XI IPS 3 at SMA Negeri 14 Medan as participants. The study centred around the subject of Arithmetic Series. First, a preliminary aptitude exam is given, and at the end of each cycle, a problem-solving aptitude test is given. After analysing the first ability test data, it was found that 18 out of 28 students, or 21%, achieved learning completion. The mean score for the test was 26.7. Following the implementation of the Reciprocal Teaching Cooperative learning model, the data analysis findings for cycle I revealed that 13 out of 28 students, equivalent to 61%, achieved learning mastery. The mean score of the class was 70.7. After cycle II, the data analysis showed that 24 out of 28 pupils, or 86%, acquired full learning. The mean score of the class was 90.86. There is an increase in the mathematical problem-solving abilities of students from cycle I to cycle II. Thus, it can be deduced that introducing the Reciprocal Teaching cooperative learning model in class XI IPS 3 at Medan State High School can improve students' aptitude in solving mathematical issues.

Abstract

The aim of this research is to improve students' mathematics learning outcomes through the problem-based learning (PBL) model using Curipod media. The research subjects consisted of 31 students of class XI TKR 4 at SMK Negeri 2 Medan, with data concentration measurement material. This type of research is classroom action research (PTK), which is carried out in two cycles, each cycle consisting of four stages: planning, implementation, observation and reflection. Based on the results of mathematics learning in the pre-cycle, it was found that only 8 out of 31 students or 25.8% achieved learning completeness, with a class average of 61.74. After implementing the PBL learning model using Curipod media in cycle I, the number of students who achieved learning mastery increased to 23 out of 31 students or 74.2%, with a class average of 76.68. At the end of cycle II, the number of students who achieved learning completion increased again to 28 out of 31 students or 90.3%, with a class average of 84.87. This shows an increase in student mathematics learning outcomes from pre-cycle to cycle II. Thus, it can be concluded that the application of the problem-based learning (PBL) model using Curipod media in class XI TKR 4 SMK Negeri 2 Medan can improve students' mathematics learning outcomes.

Abstract

This research is conducted with the intention of enhancing the learning outcomes of students in class XI-TITL 4 at SMA Negeri 2 Medan through the implementation of a problem-based learning methodology. Two cycles of four stages—planning, doing, observing, and reflecting make up the classroom action research methodology. Thirty individuals, all from class XI-TITL 4, were the subjects of this study. Tests, observations, and documentation are the means of data gathering, while descriptive analysis is the tool of choice for data analysis. According to the study's findings, pupils' average mathematics learning outcomes also improved throughout the two cycles, rising from 70.83 to 79.48. Aside from that, cycle I had a completion rate of 57% and cycle II had a completion rate of 87% for student learning. The study that has been conducted suggests that instructional materials that employ a problem-based learning approach can enhance the learning outcomes for students.

Abstract

This study aims to develop and test the effectiveness of the Al Washliyah Values-Based Meaningful Learning Model as a pedagogical approach capable of strengthening the quality of education in Al Washliyah's partner schools. The background to this research stems from Al Washliyah's internal need to provide a learning model that not only develops academic competencies but also instills Islamic values, Islamic values, and character in students holistically. Specifically, this study formulates a learning model that integrates Al Washliyah's core values ​​of faith, knowledge, and charity into meaningful learning stages, encompassing the activation of prior knowledge, the construction of new concepts,The research results show that the developed model has a very high level of validity from educational experts and Al Washliyah figures. Implementation of the model has also been proven to improve the quality of the learning process, student motivation, Islamic attitudes and character competencies, and teacher performance in planning and implementing values-based learning.internalization of values, and collaborative reflection within the context of teaching and learning activities.The research method used a research and development (R&D) approach using a modified Borg & Gall model in four stages: needs exploration, model design, expert validation, and limited implementation testing in three Al Washliyah partner schools. Data were collected through observation, interviews, questionnaires, and documentation analysis. Data were then processed qualitatively and quantitatively to assess the model's feasibility and its impact on improving learning quality. The findings of this study confirm that the integration of Al Washliyah values ​​into meaningful learning significantly enhances educational quality, particularly in Al Washliyah-supported institutions focused on developing knowledgeable, moral, and progressive individuals. This model is recommended as a pedagogical reference for Al Washliyah schools more broadly and can be developed for other Islamic educational institutions.

Abstract

This study aims to describe the types of errors and the factors causing errors made by students in solving System of Linear Equations in Two Variables (SLETV) problems based on Newman’s Error Analysis. This research is a descriptive qualitative study with the subjects being students of class IX-10 at SMP Negeri 1 Percut Sei Tuan in the 2025/2026 academic year. The data were collected through diagnostic tests, questionnaires, and interviews. The data analysis technique was carried out by identifying students' errors based on the five stages of Newman, namely reading errors, comprehension errors, transformation errors, process skill errors, and encoding errors. The results showed that students made errors at all stages of Newman’s procedure, with the dominant errors occurring at the transformation and process skill stages. These errors include students’ inability to understand the meaning of the problems, transform word problems into mathematical models, and carry out calculation procedures accurately. The factors causing students’ errors include low conceptual understanding, lack of procedural skills, lack of accuracy in answering questions, ineffective study habits, and low student attitudes toward mathematics. Based on the findings, it can be concluded that error analysis using Newman’s procedure is able to systematically identify the location of students’ errors in solving SLETV problems. Therefore, it is expected that teachers can use the results of this analysis as a basis for designing more effective learning strategies to minimize students’ errors and improve learning outcomes.
