This research is a quasi-experimental research which compares two learning models, namely the TTW cooperative learning model and the conventional learning model. This research was conducted on students of class VII SMPS Mentari Bangsa Medan, which consisted of 2 classes. This study involved two variables, namely the independent variable and the dependent variable. The independent variable is the TTW and KAM learning strategy, while the dependent variable is the mathematical communication skills and attitudes of students towards learning. The sample consist of 42 students for TTW strategy and 37 students for conventional learning. The conclusion is that students who get learning with the TTW strategy have significantly better mathematical communication skills than students who get conventional learning (tcount = 4,93 more than ttable =1,66) and the attitudes of students who get learning with the TTW strategy are significantly better than students who get conventional learning (tcount = 3,14 more than ttable = 1,66).","PeriodicalId":51086,"journal":{"name":"Journal of Database Management","volume":"2 1","pages":"50-61"},"PeriodicalIF":2.6,"publicationDate":"2021-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46378738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mathematical problem solving abilities play a role in solving every problem both other subjects and problems in everyday life. Through mathematical problem solving activities students are directed to build mathematical knowledge, think logically, systematically and measurably. The fact is that students' mathematical problem solving abilities are still low. The learning process that focuses on exercises that provide opportunities for students to develop mathematical problem solving skills to become a model for improvement in the learning process. The Missouri Mathematical Project learning model is an appropriate learning model to facilitate students in developing their thinking in solving mathematical problem solving problems. For this reason, this study aims to improve students' mathematical problem solving abilities through the application of the Missouri mathematical learning model. This type of research is a classroom action research (PTK). The research subjects were grade V students of MIS Al Firdausy Pematang Reba. The data collection technique used was a mathematical problem-solving ability test. The data analysis technique used is quantitative data analysis. Based on the results of the test of mathematical problem solving abilities, there was an increase in each cycle starting from the initial pre-action test, cycle I and cycle II. It can be concluded that there is an increase in students' mathematical problem solving abilities through the application of the Missouri mathematical learning model.","PeriodicalId":51086,"journal":{"name":"Journal of Database Management","volume":"2 1","pages":"33-41"},"PeriodicalIF":2.6,"publicationDate":"2021-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44658312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The object of this research is the students' mathematical resilience ability through the Different Instruction approach in the basic mathematics subject matter of functions. This research procedure refers to four stages, namely planning, acting, observing, and reflecting. This research was conducted in two cycles, the research was based on the criteria that reached 85% for students who produced a minimum result of 65%. The instrument used in this study was a non-test question in the form of a mathematical resilience scale given at the beginning and end of the lesson.

This study aims to analyze the difficulty of students' mathematical communication skills using the Google Classroom Application in the Algebra course. This type of research is descriptive qualitative. The subjects of this study were tree semester students who took Algebra courses in the Mathematics Education study program at Universitas Muhammadiyah Tapanuli Selatan, academic year 2020/2021 as many as 15 people. The instrument used in this study was Test and interview. The results showed that based on the test results obtained: difficulties in the ability to interpret mathematical ideas rationally in writing, difficulties in mathematical problems into mathematical models and difficulties in the ability to express mathematical ideas in the form of descriptions. Meanwhile, based on the results of the interview, namely: (1) technical difficulties, and (2) student adaptation difficulties. To overcome these difficulties, it is necessary which is a combination of Online and Offline learning or also called blended learning.","PeriodicalId":51086,"journal":{"name":"Journal of Database Management","volume":"2 1","pages":"18-25"},"PeriodicalIF":2.6,"publicationDate":"2021-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43523568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
