Abstract

Mathematics learning is designed to achieve the objective of mathematics learning, that is to stimulate students to grow their mathematical abilities. However, the activities of teaching-learning have been applying the conventional learning method, in which the teacher has full control of learning so that students' mathematical abilities are classified as low. The learning model that is applied to the solution to improve students' mathematical abilities is Student Team Achievement Division (STAD). This research involved VIII classes of SMP Negeri 50 Jakarta, which are VIII-B and VIII-D classes using a Quasi-Experimental Design. Data collection was based on a pretest, posttest, and gain data by statistical test through the Mann-Whitney U test by the calculation of the program SPSS 26 because the data is not a normal distribution and not homogeneous so that it is obtained that: (1) There is a difference in mathematical ability between students who apply STAD and Expository learning models. The average posttest score of mathematical ability between students with the STAD learning model treatment is superior to the Expository learning model, that is 66,64 and 15,78. (2) There is a difference in improving mathematical ability between students who apply the STAD and Expository learning models. The average gain score of mathematical ability between students who apply the STAD learning model is superior to the Expository learning model, that is 64,56 and 13,08.

Abstract

Since a government policy that mandated social isolation or restrictions on social interaction to prevent the spread of the COVID-19 virus, online education has been practiced in Indonesia. Various communication tools, such as Google Classroom, Google Meet, Zoom, Edmodo, or WhatsApp, are used for online learning activities. In the current state of online education, many factors contribute to students becoming sluggish or disinterested in their studies, such as the fact that it requires a high level of concentration, time, and energy, as well as feelings of compulsion to abandon some activities that, in comparison to learning, are more enjoyable. others, both positive and negative exercises. Therefore, the purpose of this study is to investigate the learning concentration level of students in class VII-H at SMPN 2 Majalaya Karawang. by employing qualitative exploratory techniques. The findings indicate that students in grades VII through H have a moderate level of concentration.

Abstract

This study aims to analyze the difficulties faced by students when solving algebraic operation problems based on the criteria of problem solving ability. This study was conducted to understand the factors that master students' difficulties in solving algebraic problems. This research used descriptive method with qualitative approach. The research subjects consisted of 35 students of class VII-G at SMP N 8 Tambun Selatan. Data were collected through observation, tests, questionnaires, and documentation. Data analysis used the Miles and Huberman data analysis model. Data validity was checked through method tringulation. The results showed that of the 35 students studied: 1) 61% of students had difficulty in understanding the problem, 2) 57% of students had difficulty in planning the solution, 3) 73% of students had difficulty in carrying out the plan, and 4) 86% of students had difficulty in checking back. The main factors that influence these difficulties are students' understanding of basic algebraic concepts, difficulties in applying mathematical concepts to the algebraic context and underdeveloped problem solving skills. In understanding math problems and formulating the steps needed to solve them, students often face difficulties.
