This research described the mathematics reasoning skill of learners taught by brain-based learning with an RME approach based on the entrepreneurship character. This descriptive qualitative research took the research 32 subjects of X graders from BDP 2 Vocational High School Swadaya Semarang in the academic year of 2021/2022. The researchers collected the data with a questionnaire, observation, documentation, and interview. The results showed the learners' mathematics reasoning skills based on their entrepreneurship characters taught by brain-based learning with the RME approach were varied. The researchers analyzed the data by reducing, displaying, triangulating, interpreting, and verifying the data. The results showed the entrepreneurship characteristics of the learners were categorized into high and moderate. The learners' mathematics reasoning skills varied based on their entrepreneurship character.

The purpose of this study was to describe the profile of students' mathematical problem-solving abilities in terms of adversity quotient. This research is qualitative research with data triangulation. The population of this study were class VIII students of SMP Negeri 13 Semarang for the 2022/2023 academic year. Determination of research subjects using purposive sampling technique, to obtain 6 subjects, namely two categories of climbers, two categories of campers, and two categories of quitters. The results of this study are students in the climbers category are able to master all stages of Polya with the NCTM indicator, namely carrying out steps to understand the problem, develop a problem solving plan, carry out problem solving, and re-check the results of the settlement, students in the campers category are able to master three of the four stages of Polya with the NCTM indicator, namely carrying out steps to understand the problem, develop a problem solving plan, and carry out problem solving, and students in the quitters category are able to master two of the four stages of Polya with the NCTM indicator, namely carrying out steps to understand the problem and develop a problem solving plan.

This research aims to describe mathematical representation abilities of Class VIII students in the implementation of the CORE learning model assisted by Canva which are reviewed from self-efficacy. The research subjects were students in class VIII C and VIII B of SMP Hasanuddin 5 Semarang. The data source in this research is students, obtained from tests result on students' mathematical representation abilities, self-efficacy dimension questionnaires, and interview. The research results show that there is a positive influence on self-efficacy on mathematical representation abilities, participants' mathematical representation abilities Students in terms of self-efficacy vary, in low, medium, and high categories. Subject with low self-efficacy were 5 (25%), subjects with moderate self-efficacy are 10 (50%), and subjects with self efficacy are 5 (25%).
