Research with descriptive methods to determine the representation construction that students use when given the task of solving three dimensional word problem. The results showed two constructs of representation, namely: pictorial representation and schematic representation. Students who construct pictorial representations produce correct answers while students who construct schematic representations produce correct answers in solving three-dimensional word problems.","PeriodicalId":137292,"journal":{"name":"Journal of Research on Mathematics Instruction (JRMI)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134213364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many studies suggest that the ability of Indonesian students to solve problems is still relatively low. Students are not allowed or encouraged to optimize their potential, develop reasoning and creativity, thereby causing the knowledge provided to be less meaningful. The success of this study was determined through three effectiveness criteria. This research design used by giving assignments to students. Assignments were completed using strategies chosen by students. The task is reflected and then evaluated. This process is carried out in the mathematics class. The class chosen is a 7th grade mathematics class with statistics and Opportunities. The three criteria are (1) the average mastery of teaching materials students meet the KKM, (2) student activities according to the syntax of the SRL Model, (3) students' responses to the learning of the SRL Model are Positive. The results of the application of the SRL model that has been done. First, students are able to complete the category very well. This is evidenced by the achievement of the average score of Mastery of Teaching Materials above the KKM score. Second, student activities are in the active category. This is indicated by the average score of the observers during the four meetings included in the active category in learning. Third, students' responses to learning have been positive.","PeriodicalId":137292,"journal":{"name":"Journal of Research on Mathematics Instruction (JRMI)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133947905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Linear program material has the potential to be developed visually using computer devices to facilitate students in understanding the linear programs. The aim of the study was to develop ICT-based mathematics learning media that met the validity, practicality and effectiveness. The instruments used in this research were material validation sheets, media validation sheets, response questionnaires and student achievement test. Questionnaire sheets were analyzed quantitatively and qualitatively. Based on the results of data analysis and discussion, it can be concluded that the ICT-based media of mathematics learning is valid with an average score of 3.36 by the material validator and 3.42 by the media validator. This learning media also fulfills practical requirements with an average student response of 3.45 in small group trials and 3.18 in large group trials. Learning media also influence students achievement learning. Student achievements in this research are in sufficient criteria that is 65.21%.","PeriodicalId":137292,"journal":{"name":"Journal of Research on Mathematics Instruction (JRMI)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131808614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
