This study aims to describe mathematical problem-solving ability based on the level of self-confidence. This type of research is a qualitative descriptive study with a quantitative approach. The data collection technique in this research is to provide test (10 multiple choice questions and 2 description questions), questionnaires, and interviews. The results showed that students with high level of self-confidence with high mathematical problem-solving abilities were able to achieve 3 out of 4 indicators of assessing problem solving abilities well, namely indicators of understanding problems, devising a plan, and carrying out the plans. Students with high level of self-confidence with moderate math problem solving abilities are able to achieve 1 of 4 indicators well, namely carrying out the plans, achieve 2 of the 4 indicators quite well, namely indicators of understanding problems and devising a plan, and less able to achieve 1 of 4 indicators namely looking back indicators. Students with high level of self-confidence with low math problem solving abilities are able to achieve 1 of 4 indicators well, namely indicators of understanding the problem. However, it does not reach 3 indicators, namely devising plans, is carrying out the plan and looking back.

Math Problem Solving

The problem in this study is the low ability of students to solve problems. That is because students only refer to the examples of questions given by the teacher so that students have difficulty if given questions that are not the same as the examples given by the teacher. Diverse problem solving solutions are needed because students still find difficult to draw conclusions from the questions they have worked on. The purpose of this study is to describe students' ability to solve trigonometric problems in terms of the personality type of Myer-Briggs, namely ISTJ, ESFJ, ESTP, INFJ, ISTJ, ISTP, ESTJ, INTP and ISFJ. This research is a type of descriptive research using a qualitative approach. Methods of data collection using the MBTI questionnaire, math problem solving ability test questions and interviews. The results showed that the ISTJ personality type fulfilled 4 indicators of problem solving very well, while the personality types of ESFJ, ESTP, INFJ, ISTJ, ISTP, and ESTJ met 4 indicators of problem solving well, and for personality types ENTJ, INTP, and ISFJ were sufficient good by meeting 3 of the 4 indicators of problem solving. The results of the study can be used to improve students' mathematical problem solving abilities by further enhancing the positive characteristics present in students. Can inspire students to better understand the type of personality they have in themselves and hone their abilities to be more improved.

Substandard Performance

Physics and Mathematics are two deeply interlinked domains of Science. Mathematics is considered as the language in which the Physics theories are built by employing mathematical symbols and operations to make equations and representations in the world of Physics completely meaningful. In spite of being the backbone of Physics, the use of Mathematics principles and operations in Physics is the root cause of most of the issues and hassles aroused among students who learn Physics. This is an investigation on the substandard performance in mathematical problem solving in Physics among higher secondary school students by looking into the responses of teachers and students. The responses obtained from 21 higher secondary Physics teachers through questionnaire were studied using percentage analysis and the four major categories of ‘Difficulties in Mathematical Problem Solving in Physics’ faced by students viz., ‘Creating or Identifying the Formula’, ‘Extracting Information from Diagrams’, ‘Using Physics Concepts to Create Schematic Diagrams’ and ‘Application of Mathematics’ to solve Physics problems. were identified, The investigators used ‘Test on Mathematical Problem Solving in Physics’ with 40 multiple choice questions on select basic topics from ‘Motion’, which was informed by the Physics teachers to be one of the strenuous concepts for students while solving problems. The extent of each category of difficulty in the respective topics based on the students’ responses in the test was studied to rank them. This study also highlights some suggestions for improving the teaching and learning of mathematical problems in Physics at higher secondary level.
