Abstract

The aim of this research is to obtain students' visual thinking profiles in understanding and applying derivative concepts. Qualitative research methods are used with the steps determining the subject, developing questions, collecting data, interpreting, presenting, reducing, categorizing, coding, and triangulating data, analysing data, and drawing conclusions. The subjects of this research were students of the mathematics education study program of PGRI Madiun University. At first, students understand the concept of derivatives without using visual thinking skills. Students understand the concept of derivative as a demotion. After learning, students understand the concept of derivatives with images as visualization. Students apply the concept of guidance without using visual thinking. After learning, students can apply derivative concepts by using images as visualization. Students understand that they must apply derivative concepts and explain with pictures or graphs. Students plan by analysing and then using function graphs to explain it. Students carry out plans by calculating analytically and completing explanations using pictures or graphs. Students check again by paying attention to the answers from friends beside them and discussions with the lecturer.

Abstract

This research is conducted due to the low learning motivation of students, which affects their mathematics academic performance. This is caused by differences in students' backgrounds, which can trigger adolescent issues such as choosing friends, refusing advice, and so on. As a result, some students become reluctant to interact and their motivation in learning decreases. The purpose of this study is to find solutions or strategies that can be applied to improve students' learning motivation, particularly in mathematics, so that their academic achievement can improve. Additionally, this research is expected to provide an overview of the importance of positive social interactions among students to support a more effective learning process. to improve students' achievement and learning motivation through the Problem Based Learning model with the Social Emotional Learning (SEL) approach in class VIII in mathematics lessons at SMPN 1 Madiun. This type of research is classroom action research which is carried out with stages in each cycle including planning, implementation, observation, and reflection. The subjects of the study were 32 students in class VIII B at SMPN 1 Madiun. The instruments used in this study were observation sheets, learning motivation questionnaires, initial ability tests and student worksheets. The data analysis used was qualitative and quantitative data analysis. This study was conducted in 2 cycles, and each cycle consisted of 2 meetings. The results of this study showed an increase in achievement from an average in the first cycle of 71.87% to 81.25%. In addition, there was also an increase in students' learning motivation from the beginning of 51.04% to 69.78% in cycle I and to 81.22% in the second cycle.
