This study aims to analyze mathematical problem solving abilities in mathematics learning based on the personality types of students. The research method used in this study is a descriptive method with a qualitative approach. The subjects of this study were 6 students of SMP Tunas Teladan Palembang in the odd semester of the 2021/2022 academic year. Subjects were taken using purposive sampling technique, based on the personality type of the students. Data analysis in this research is qualitative data analysis which consists of data reduction, data presentation and conclusion drawing. From this study, it was concluded that: (1) students with extroverted personality type were able to meet problem solving indicators at the stage of understanding problems, planning and solving problems, but did not meet indicators at the re-examining stage (2) students with introverted personality types were able to fulfill all problem solving indicators at the stage of understanding the problem, making plans, solving problems and checking again.

The development of android learning media becomes one of the alternatives in learning, especially in circle materials. The purpose of this research is to produce android-based learning media on valid and practical circle material. This type of research is development research with the ADDIE development model. The research subjects consisted of 17 students. This research data is obtained from questionnaires, interviews, and documentation. This research produces: (1) Learning media that are classified as valid based on validator comments and suggestions, (2) Learning media that are relatively practical based on the results of student comments and suggestions on questionnaires and interviews.

This study aims to develop E-LKPD based on the Contextual Teaching and Learning (CTL) Approach on the material of circles with a woven context for grade VIII junior high school students. This development research uses the Tessmer model consisting of a preliminary stage including analysis of students, curriculum, and teaching material needs, while the prototyping stage includes design, validation, and trial of E-LKPD. Data collection was carried out using interview methods, observations, questionnaires, and concept understanding tests. Based on the analysis results, it was found that students still experience obstacles in understanding the concept of circles due to limited context-based teaching materials and the unavailability of a curriculum that supports the integration of local wisdom, such as the use of woven rope. The developed E-LKPD is considered to have met the validity criteria (average score of 89.7%), practical (average score of 84%), and had a potential effect (average score of 88.8%). The CTL approach with a woven context increased students' motivation, involvement, and appreciation of local culture. This study produced an E-LKPD that was suitable for use as an interactive mathematics learning media that was relevant to students' daily lives.

E-Modules are a form of independent learning media designed to cover a specific topic or material. This study aims to develop Canva-based mathematics learning media on the material of flat-sided solid shapes with a guided discovery approach that has a level of validity, practicality, and potential effects on improving students' conceptual understanding. The type of research applied is design research with a development study type, using the Tessmer procedure which includes two main stages, namely the preliminary stage and the prototyping stage through a formative evaluation process, which consists of self-evaluation, one-to-one, expert reviews, small group, and field test. The material in the e-module is arranged based on guided discovery indicators, while the evaluation tool is developed referring to the conceptual understanding indicators. Data collection techniques include interviews, tests, validation sheets, and questionnaires. The research subjects are grade VIII junior high school students. The results of the study indicate that the developed learning media has met the valid criteria based on the results of expert validation, practicality according to the results of student response questionnaires, and has a potential effect in improving students' mathematical conceptual understanding abilities.
