Abstract

This research investigates the application of the cooperative learning model, specifically the Team Assisted Individualization (TAI) approach, in enhancing the learning outcomes of high school students in the topic of System of Linear Equations in Three Variables (SPLTV) at SMA Negeri 2 Manado. The study is motivated by the challenges students face in mathematics, particularly in contextual problems and mathematical modeling, leading to outcomes that do not meet the Minimum Completeness Criteria (KKM). The research employs a quasi-experimental design, contrasting one class utilizing the TAI model with another using conventional teaching methods. Data were collected via pre-tests and post-tests, which revealed a significant difference in average scores favoring the TAI model. Results indicate that TAI not only improves knowledge but also engages students actively, promoting collaboration and reducing the perception of mathematics as a difficult subject. The study suggests the integration of cooperative learning strategies to enhance student motivation and understanding in mathematics education, contributing to the development of effective teaching methodologies.

Abstract

This study aims to determine whether the average learning outcomes of students using the problem based learning model are higher than the average learning outcomes using the direct learning model on social arithmetic material. This study uses a quasi-experimental method, with a Post-test Only Control Group Design research design. The subjects of this study were students in class VII of SMP Negeri 1 Siau Timur Selatan, which consisted of two classes, namely class VIIA as an experimental class using the problem based learning model and class VIIB as a control class using the direct learning model. Data collection was obtained by giving a pest test to both classes after the treatment was carried out. Research statistics were analysed using the t-test, hear the tvalue = 3,349638 > ttable = 2,00665 means H0 is rejected. Thus it can be concluded that the average learning outcomes of students taught with the problem based learning model are higher than average learning outcomes of students taught with the direct learning model

Abstract

This study aims to identify whether the learning outcomes of students who learn using the Numbered Head Together (NHT) learning model are higher than the learning outcomes of students who learn using the Conventional learning model on Cartesian Coordinates material. This research is a study that uses a posttest-only control group design. The population of this study were all students of class VIII and the samples in this study were class VIII A as an experimental class consisting of 30 students and class VIII B as a control class consisting of 30 students at SMP N 2 Amurang in the academic year 2024/2025. The results revealed that there were differences in the learning outcomes of students taught using the Numbered Head Together (NHT) learning model with students taught using the Conventional learning model. Based on the above results, it is concluded that learning by using the Numbered Head Together (NHT) learning model can improve students' mathematics learning outcomes on Cartesian Coordinates material.

Abstract

This study aims to determine whether there is an effect of applying the Snowball Throwing cooperative learning model on mathematics learning outcomes in grade VII on the subject of Algebraic Operations at SMP Negeri 2 Tondano using quantitative research through an experimental method with two classes randomly selected as subjects. The research instrument was a post-test consisting of multiple-choice and essay questions that had been tested for validity and reliability. From the hypothesis testing using the t-test, tcount = 5.567 > ttable = 2.023, which means rejecting Ho. Therefore, it can be concluded that the average learning outcomes of students on the subject of algebraic operations using the Snowball Throwing model are higher than the average learning outcomes of students using the conventional learning model.

Abstract

This study aims to determine whether there is a difference between the average learning outcomes of students students taught using the Problem-Based Learning model and those taught using the direct instruction model on the topic of Linear Equations. The research design employed was a Pretest–Posttest Control Group Design. The sample consisted of class VIII B with 24 students as the experimental group and class VIII C with 20 students as the control group. The data analysis technique used was the t-telst. Based on the t-test results with a significance level of ( ), the obtained value was = 3,9699 > = 2,018, indicating that  is rejected and  is accepted. This mean that there is a difference between thel average learning outcomes of students taught using the Problem-Based Learning (PBL) model and those taught using the direct instruction model on the topic of Linear Equations
