KAJIAN KEMAMPUAN SELF-EFFICACY MATEMATIS SISWA DALAM PEMECAHAN MASALAH MATEMATIKA
Get PDFAbstract: Self-efficacy is related to a person's judgment of student ability to solve something. This ability to be one that supports the successful completion of the task well, it can be said that self-efficacy support students' mathematical abilities. This ability becomes a powerful predictor of problem solving. This article aims to examine students' mathematical self-efficacy abilities in mathematical problem solving. The method used is to collect the data library without empirical test. Self-efficacy is important role in everything, especially for students who are solto solve mathematics problem. Given the high self-efficacy capability in the student is expected to succeed in solving mathematics problem. Students with high mathematical self-efficacy are better able to solve mathematical problems well and student failures in solving mathematical problems are assumed for lack of effort or learning. Conversely, students with low mathematical self-efficacy tend to be vulnerable and easily give up in solving mathematical problems and student failures in solving mathematical problems are assumed for their lack of mathematical ability.Keywords: Problem Solving, Self-Efficacy

PEMBELAJARAN MATEMATIKA SMP DALAM PERSPEKTIF LANDASAN FILSAFAT KONSTRUKTIVISME
Get PDFAbstract: Constructivism is one of the views in learning theories that affect much of the learning of mathematics. According to experts, the view of mathematics learning as discovery and construction by students is better than the abstract set of science informed by the teacher. Junior high school students are students who begin to be introduced and understand abstract way of thinking, so students should not be taught by way of rote memorization without meaning, especially on learning mathematics filled with abstract symbols. This article aims to describe the learning of Junior high school mathematics in constructivism perspective: planning, process, assessment of learning, role of student and teacher role. This article is using library research method. The data collected and analyzed are secondary data in the form of research results including books, journal articles and conference proccedings relevant to the topic. The results show that constructivism is a new way of thinking that knowledge is not only through the transfer process, but the knowledge grows and develops from activities, such as the activity of constructing the concept of variables and constants using the help of contextual problems. Assessment used in learning mathematics in the perspective of constructivism is formative and summative assessment. The role of students in junior mathematics learning with constructivism approach focuses on student activity in constructing their own knowledge and its consequences. Meanwhile, the role of teachers in junior high school mathematics with constructivism approach is divided into two namely the teacher as a facilitator and moderator.Keywords: Teacher, Constructivism, Mathematics Learning, Studen
