The purpose of this study was conducted to determine: (1) how is the description of critical thinking skills, emotional intelligence and learning independence of grade VIII students of SMP Negeri 1 Sungguminasa. (2) whether there is an influence on the ability to think critically, emotional intelligence and independent learning together on the mathematics learning outcomes of class VIII students of SMP Negeri 1 Sungguminasa. (3) whether there is a positive influence on the ability to think critically on the mathematics learning outcomes of grade VIII students of SMP Negeri 1 Sungguminasa. (4) whether there is a positive effect of emotional intelligence on the mathematics learning outcomes of grade VIII students of SMP Negeri 1 Sungguminasa. (5) whether there is a positive effect of independent learning on the mathematics learning outcomes of grade VIII students of SMP Negeri 1 Sungguminasa. This type of research is an ex-post facto research which is causality with a research sample of 57 students from class VIII SMP Negeri 1 Sungguminasa in the 2019/2020 school year using the sampling technique using cluster random sampling method. Data collection techniques using tests, questionnaires and documentation. The data analysis technique used descriptive statistics and inferential statistical analysis. The results showed that: (1) critical thinking skills, emotional intelligence and learning independence of class VIII students of SMP Negeri 1 Sungguminasa were in the good category while the mathematics learning outcomes of grade VIII students of SMP Negeri 1 Sungguminasa were in very high criteria. (2) the ability to think critically, emotional intelligence and independent learning together have an effect on the mathematics learning outcomes of grade VIII students of SMP Negeri 1 Sunggguminasa. (3) the ability to think critically has a positive effect on the mathematics learning outcomes of grade VIII students of SMP Negeri 1 Sungguminasa. (4) emotional intelligence has a positive effect on the mathematics learning outcomes of grade VIII students of SMP Negeri 1 Sungguminasa. (5) independent learning has a positive effect on mathematics learning outcomes of class VIII students of SMP Negeri 1 Sungguminasa.

Learning models are necessary because one of the purposes of using learning models is to improve students' abilities. One of the learning models that can be used in elementary school is role-playing. This study aims to know the effectiveness of using role-playing in mathematics learning, especially in an arithmetic operation. This research used quantitative research with a pre-experimental design; it’s a one-shot case study. This research's subject was Elementary School 278 Padakallawa's fourth-grade students at Pinrang Regency, South Sulawesi. The data were obtained using two instruments: learning achievement test sheets and activity observation sheets. The collected data are analyzed using descriptive statistics. The result showed that the implementation of role-playing in mathematics learning achieved the established effectiveness indicators, which are (1) the percentage of learning activities was in the good category of 61.11%, and (2) learning mastery was classically 90.5% exceeding the set standard of 85%. It can be concluded that role-playing can develop students’ character and can be a very effective way to increase their creativity and self-confidence.

The purpose of the study was to describe the types of student errors and the factors that caused students to make mistakes in solving a two-variable system of linear equations based on Watson's criteria for class VIII MTs Pattuku. This type of research is descriptive research using a qualitative approach. The subjects in this study were students of class VIII MTs Pattuku then chose 3 subjects to be interviewed who had the most types of errors based on Watson's criteria. The research instrument used was a diagnostic test consisting of 3 questions about a two-variable linear equation system and interview guidelines. From the results of this study, it shows that there are no students who make mistakes in missing data (committed data) and indirect manipulation (undirected manipulation). 16% made incorrect data errors (innapropriate data), 40% made incorrect procedural errors (innapropriate procedure), 68% made an omitted conclusion error, 24% made a response level conflict error, 36% made mistakes in the skill hierarchy problem, and 48% made mistakes other than the 7 categories above (above other).
