One of the important affective factors for students in mathematics learning is self-efficacy. The students should have high mathematics self-efficacy. So, it can support the success of learning process. The facts that indicated the low of students' mathematics self-efficacy, encouraging the efforts to improve self-efficacy through the improvement…

Improving self-efficacy in the learning process of Mathematics is very important as the key to success in learning Mathematics. Self-efficacy in learning mathematics is a belief in one's ability to solve mathematical problems. Many studies have been conducted on the relationship between self-efficacy and students' mathematics learning ability in…

Background: The results of the Programme for International Student Assessment (PISA) 2012 showed that Indonesia, Malaysia, and Thailand underperformed and were positioned in the bottom third out of 65 participating countries for mathematics, science, and reading literacies. The wide gap between these three countries and the top performing…

The aim of this study was to analyze the effectiveness of learning materials through Problem Based Learning with Karo Culture Context (PBL-KCC), as well as improving students' mathematic problem solving ability and student self-efficacy. Learning materials developed were lesson plan, student book, student worksheet, mathematic problem solving…

Geometry mastery is a must for high school students, affected by several factors such as learning approach (LA), gender, level of basic geometry competencies (BGC) and level of mathematical self-efficacy (MSE) among others. The purpose of this study is to examine those factors that affect the geometry problem solving (GPS) abilities of the…

Numerical thinking is needed to recognize, interpret, determine patterns, and solve problems that contain the context of life. Self-efficacy is one aspect that supports the numerical thinking process. This study aims to obtain a numerical thinking profile of Mathematics pre-service teachers based on self-efficacy. This study used descriptive…

Strengthening self-efficacy and motivation in learning mathematics gives impacts on the students' capability in the field of mathematics, and this may be conducted through a proper learning model, one of which is the cooperative learning model. The objective of this present research was to analyze students' self-efficacy reinforcement and their…

Calculus differential is the basis of mathematics before entering the level of further mathematics, which has a high analysis level. Students have difficulty understanding concepts and have not been able to analyze/predict/realize (self-efficacy) that impact challenges in working on calculus problems. On the other hand, technology has been…

This study aims to analyze the effectiveness of learning materials based on realistic mathematics education approach, as well as improving mathematical problem solving ability and student self-efficacy. Learning materials that developed were lesson plan, student book, student worksheet, mathematical problem solving ability test and self-efficacy…

This research aims at comparing the self-efficacy of primary school (SD, "Sekolah Dasar") teachers who had taken teacher training program (PPG, "Program Pelatihan Guru") on Mathematics teaching and vice versa in which it was seen from the personal belief subfactors in teaching Mathematics and the expectation of mathematics…

The common problems faced by most students in learning mathematics include their inability to answer problem-solving questions and low mathematical self-efficacy. Search, Solve, Create and Share (SSCS) is a teaching model that provides opportunities for students to enhance their problem-solving skills and self-efficacy. This quasi-experimental…
