This study aims to determine whether there are differences in the ability to solve problems and think creatively in mathematics students who are taught with the problem based learning model with the two-stay-two stray cooperative learning model in class X SMA Negeri 2 Range of TP 2018 / 2019. This research is research quantitative research with quasi-experimental type. This sampling technique uses the Cluster Random Sampling technique. The sample of this study was students of class X-1 and X-2 of SMA Negeri 2 Kisaran T.P 2018/2019, amounting to 60 students. The test instrument used to determine students' creative problem solving abilities and mathematical creative thinking is to use a test in the form of a description. Data analysis was performed by analysis of variance (ANAVA). These findings show: 1). There is a difference in the ability to solve mathematical problem of students who are taught with the Problem Based Learning model and the Two Stay-Two Stray cooperative learning model in the material of the Three Variable Linear Equation System; 2). There is no difference between students' creative thinking abilities in mathematics taught by the Problem Based Learning model and the Two Stay-Two Stray cooperative learning model in the Three Variable Linear Equation System material; 3). There is a difference in the ability of problem solving and mathematical creative thinking of students who are taught with the Problem Based Learning model and the Two Stay-Two Stray cooperative learning model in the material of the Three Variable Linear Equation System; 4). There is no significant interaction between the learning models used on the problem solving abilities and students' mathematical creative thinking in the Three Variable Linear Equation System material. The conclusions in this study explain that there are differences in students' problem solving abilities and creative mathematical thinking that are taught with the Problem Based Learning Model and the Two Stay-Two Stray Cooperative Learning Model.

The purpose of this study was to increase the activities and learning outcomes of Mathematics in the material of the Two-Variable Linear Equation System for class VIII-1 students of MTsN 2 Aceh Besar in the 2019/2020 academic year. The model used in this research is the Problem Based Learning model. The subjects of this study were students of class VIII-1 MTsN 2 Aceh Besar. The number of students is 32 students with 10 male students and 22 female students. This research was conducted in the 2019/2020 school year in a period of 3 months, from September 2019 to November 2019 in the odd se-mester. The research methodology is Classroom Action Research (PTK) consisting of two cycles and each cycle consisting of two meetings. Each cycle consists of planning, implementing, observing and reflecting. The research procedure consisted of pre-research, planning cycle one, implementing action cycle one, observing cycle one, reflecting cycle one, planning cycle two, implementing action cycle two, observing cycle two and reflecting cycle two. The data collection technique is to collect test scores that are carried out at the end of each lesson in each cycle using a question instrument (written test). Obser-vation data was carried out by looking at the activeness of students in the learning process. Data were analyzed by means of percentage statistics. The results showed that there was an increase in the com-pleteness of student learning outcomes from 34.37% in the pre-study increased to 59.37% in the first cycle and increased to 84.37% in the second cycle. Student learning activities have increased from suffi-cient to good categories and good categories have increased to be very good. The application of the Problem Based Learning model can increase the activities and learning outcomes of Mathematics in the material of the Two Variable Linear Equation System for class VIII-1 students of MTsN 2 Aceh Besar in the 2019/2020 academic year.

Technological progress is very rapid, especially in the field of education, so teachers and students need to use technology in learning. ICT-based learning media is one of the uses of technology in education with the hope of improving the quality of learning. This study aims to determine the process and produce a product in the form of-based learning media flipbook on the material of a two-variable linear equation system in class VIII SMP. This research is a development research using the ADDIE development model. The data collection technique used is a non-test technique with a data collection instrument in the form of a validation sheet filled out by the validator. Data analysis used quantitative descriptive data analysis. Overall, the feasibility assessment of-based mathematics learning media flipbook on two-variable linear equation system material obtained an average of 85.70%, so-based learning media flipbook on two-variable linear equation system material in class VIII SMP is interpreted as very valid for use.Keywords: Learning Media, Flipbook, Material of Two Variable Linear Equation Systems, Validity

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).
