The study aims to (1) analyze the improvement of student achievement in learning after scaffolding, (2) evaluate the level of students 'mathematics anxiety, and (3) describe the role of scaffolding in changing students' perceptions of mathematics anxiety in classroom learning. Sampling through random sampling techniques obtained by students of class X-IPA-1 and X-IPA-2 in SMA Negeri 6 Semarang. Quantitative data analysis uses statistical test techniques: normality test, paired sample t-test, and N-gain test. Qualitative data analysis through interactive methods namely data collection, data reduction, data presentation, and drawing conclusions. Data validation techniques through the source and method triangulation. The results showed that (1) there was an increase in student learning achievement after the application of the scaffolding strategy by 33.0% to 34.5%; (2) there was a decrease in the level of mathematics anxiety in students by 90.4%; (3) through scaffolding, students succeed in reflecting and correcting mistakes in solving previous problems. This means scaffolding can be an effective strategy to help students move across different Zones of Proximal Development (ZPD). The scaffolding strategy has also created a positive classroom environment that encourages students to learn mathematics without fear.","PeriodicalId":31996,"journal":{"name":"Numerical Jurnal Matematika dan Pendidikan Matematika","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42106269","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}

This research was an experimental study in the category of one group pretest posttest design involving 30 first semester students of mathematics education study program at STKIP Muhammadiyah Pagaralam. The results showed that students’ mathematical communication skills during the applied scientific approach using graphmatica software on function graph material were classified as very good. This means that the use of graphmatica software through the scientific approach can build students’ mathematical communication skills. Through the learning process based on a scientific approach consisting of observing, quetioning, associating, experimenting, and networking, students’ mathematical communication skills both verbally and in writing are classified as very good. For this reason, these activities have a positive influence on students. Beside building students’ mathematical communication this approach also influence students’ learning outcomes. Better the mathematical communication skills, better the learning outcomes. Therefore, building mathematical communication skills is very important in learning especially in learning through a scientific approach using graphmatica software. The use of graphmatica software can be used in other course such as calculus courses. So, graphmatica software can be used in other course so that it is not limited according to the design of the material to be implemented.","PeriodicalId":31996,"journal":{"name":"Numerical Jurnal Matematika dan Pendidikan Matematika","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49085313","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}
