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.

Problem solving must be developed and internalized in mathematics<br />learning, so students have problem solving skills that students can<br />transfer to their daily lives when facing problems or difficulties.<br />There is a mental attitude that affects a person's success to become a<br />successful problem solver, namely adversity quotient. This mental<br />attitude affects the mindset and emotions so it is not easy to give up<br />in solving problems. This study aims to measure the relationship<br />between adversity quotient and problem solving abilities of junior<br />high school students in mathematics learning. This research is a<br />correlation study. The population was students of SMPN 1 Padang<br />Panjang 2014/2015 academic year, while 32 samples were selected<br />by purposive sampling. The data was collected using an adversity<br />quotient scale and a mathematical problem solving ability test. Data<br />were analyzed by regression correlation techniques. The results of<br />data analysis showed a correlation coefficient between adversity<br />quotient variables with mathematical problem solving abilities of r =<br />0.756&gt; rtable (0.297), meaning that there was a significant positive<br />relationship between adversity quotient and mathematical problem<br />solving abilities. The coefficient of determination obtained is r2 =<br />0.572 indicating that adversity quotient has an effect of 57.2% on<br />mathematical problem solving abilities of junior high school<br />students, while 42.8% is influenced by other factors
