Corresponding Author: Refiesta Ratu Anderha DOI: https://doi.org/10.52403/ijrr.20230772 ABSTRACT Opportunity is material at the junior high school level that is easy to relate to the problems of everyday life. Even so, there are still findings that show students' difficulties and errors in solving opportunity problems. Students' disbelief in their ability to solve problems is thought to be an obstacle for students, besides that the learning model and approaches implemented in schools are one of the factors in improving students' problem-solving abilities. However, further research is needed to prove it. This study aims to analyze the effectiveness of flipped classroom learning with a scientific approach in terms of student self-efficacy, as well as to describe students' mathematical problem-solving abilities on opportunity material in terms of students' self- efficacy in solving problems. The research subjects were class VIII students of SMP IT Insan Cendekia Semarang. The results of the study show that flipped classroom learning with a scientific approach is proven to be effective in improving students' problem-solving abilities. In addition, the level of self-efficacy of students also shows that students who are in the category of higher self-efficacy tend to have better problem-solving skills. This result is proven by The results of the study show that flipped classroom learning with a scientific approach is proven to be effective in improving students' problem solving abilities.

In addition, the level of self-efficacy of students also shows that students who are in the category of higher self-efficacy tend to have better problem-solving abilities. This result proven that there is an influence between students' self-efficacy on the mathematical problem-solving abilities of students who are taught using the flipped classroom learning model with a scientific approach. So, in other words, self-efficacy has a positive effect on students' problem-solving abilities. Keywords: problem solving ability, flipped classroom, self-efficacy, scientific approach INTRODUCTION Education is essentially a process to prepare humans to survive in their environment. [1] Education is said to be successful if positive changes occur in students both in terms of knowledge, abilities, behavior, and attitudes that can be used in social life through the teaching and learning process at school. [2] According to the National Council of Teachers of Mathematics (NCTM) there are five mathematical abilities that students must have, namely problem solving skills, reasoning skills, communication skills, and the ability to make connections, and the ability to representation. [3] Problem solving abilities have become an important issue in mathematics education and should be a focus in learning mathematics in schools, as well as many mathematical abilities that also intersect in problem solving.
