Abstract

This research is motivated by the students’ poor understanding of mathematical concepts, so that they frequently did not complete the tasks submitted by the teacher. The research aims to determine whether implementing cooperative learning model Team Games Tournament (TGT) is better than the conventional learning to improve student’s understanding of mathematical concepts for VIII-grade students of MTsN Limbanang, 50 Kota. This research is experimental, using random sampling of population.  The population studied is five classes of VIII-grade students of MTsN Limbanang, 50 Kota. Samples taken ramdomly from the selected classes: VIII.1 class as the experimental class and VIII.2 class as the control class. The instrument used in this study is a test of students’ understanding of mathematical concepts. The test form is essay with reliability r11=0.869. From the data analysis obtained the mean of the experimental class is 76.6 and 61.9 for the control class. The one side test of hypothesis (t-test) using MINITAB shows Pvalue 0.002 which less than α 0.05; so that the hypothesis proposed on the trust level 95% is accepted. It can be concluded that the students understanding of mathematical concepts by implementing cooperative learning Team Games Tournament ( TGT ) is better than conventional learning.

Abstract

This study aims to identify students' errors in modeling story problems on SPLTV material using the Newman analysis approach. This study was conducted at SMAN 6 Bengkulu City involving 36 students of class X F as subjects. Data were collected through a written test with two HOTS-based questions. Error analysis was carried out using Newman indicators, including reading, understanding, transformation, process skills, and writing/encoding errors. The results showed that students faced various obstacles, especially in understanding questions and converting information into mathematical models. The main factors causing errors were a lack of understanding of basic algebraic concepts, being less careful in reading questions, and minimal practice of story-based questions on SPLTV material. These findings provide recommendations for teachers in developing more effective learning strategies to overcome student obstacles.
