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.

AbstractThis study aims to improve students' problem-solving abilities with STAD cooperative learning model on the subject of integers class VII SMP Negeri 3 Galang. This type of  research is a classroom action research. The subjects were students of class VII-1 SMP Negeri 3 Assemble TA2014/2015 which amounted to28 students. The object of  this study is an effort to improve the ability of mathematical problem solving through cooperative learning model Student Team Achievement Division(STAD) on the subject of Integer. The research instrument used is the observation and mathematical problem solving ability test.  From the results of problem solving ability test, the data obtained were 9 students (32.14%), which reached the criteria of problem-solving abilities. After being given the treatment by applying the learning model STAD (first cycle), it is provided TKPMI .From the TKPMI data showed that as many as16students(57.14%) of the28students(2.74 value) that reaches criteria problem-solving abilities. This shows that in the first cycle of mathematical problem solving ability of students as a whole h as not reached 85%, the continued action on the second cycle. From the results TKPMII data showed that as many as 24 students (85.71%) of  the 28 students (3.15 value) that reaches criteria problem-solving abilities. This shows that the mathematical problem solving ability of students as a whole has reached 85%, then the action is stopped. Based on t he above results, it can be concluded that by applying STAD cooperative learning model can improve students' mathematical problem solving ability on the subject of integers in class VII SMP Negeri 3Galang.Keywords: STAD, improve, test, problem, solving

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

Problem-solving ability is a characteristic of mathematical activities and a major ability in developing mathematical understanding. Mathematical problem-solving ability can be seen from several dimensions, one of which is cognitive style. Cognitive style is a unique way for each individual to acquire, process, store, use the information to respond to tasks or situations, and build knowledge. FD and FI cognitive styles are one type of cognitive style that are categorized by general ways of thinking, solving problems, learning, and dealing with other people so that they have a relationship with problem-solving abilities. The subjects in this study involved 72 students (around the age of 13-14 years), namely 33 students with FD cognitive style and 39 students with FI cognitive style. The problem-solving ability test instrument in this study was a mathematical problem-solving ability test that had been validated by experts and tested for reliability. The cognitive style test instrument is the Group Embedded Figure Test (GEFT) item developed by Witkin. The problem-solving ability of junior high school students with FI cognitive style is better than FD students even though the difference is not much different.

Problem solving is a basic skill that should be possessed by students. Mathematical problem solving abilities play a role in solving every problem both other subjects and problems in everyday life. Through mathematical problem solving activities students are directed to build mathematical knowledge, think logically, systematically and measurably. The fact is that students' mathematical problem solving abilities are still low. The learning process that focuses on exercises that provide opportunities for students to develop mathematical problem solving skills to become a model for improvement in the learning process. The Missouri Mathematical Project learning model is an appropriate learning model to facilitate students in developing their thinking in solving mathematical problem solving problems. For this reason, this study aims to improve students' mathematical problem solving abilities through the application of the Missouri mathematical learning model. This type of research is a classroom action research (PTK). The research subjects were grade V students of MIS Al Firdausy Pematang Reba. The data collection technique used was a mathematical problem-solving ability test. The data analysis technique used is quantitative data analysis. Based on the results of the test of mathematical problem solving abilities, there was an increase in each cycle starting from the initial pre-action test, cycle I and cycle II. It can be concluded that there is an increase in students' mathematical problem solving abilities through the application of the Missouri mathematical learning model.

The purpose of this study was to study and analyze students' problems in problem-solving skills seen from their mathematical disposition level of the students on 12th grade class of  SMA IT Fithrah Insani. Method of this study is descriptive- qualitative research. From 35 students, there were three students taken as samples, consisting of a student with high disposition mathematical ability (T), a student with medium disposition mathematical ability (S), and a student with low disposition mathematical ability (R). The result of the study shows that there is a difference in the average score of students in each level of the mathematical disposition towards the conclusion of the students’ mathematical problem-solving ability test (ANOVA Test-One way). Following up on these differences, researchers identified student achievement and misconceptions on each mathematical problem-solving indicators. The results of the study show that all the student with high and medium disposition mathematical ability could not fulfill the indicators of the ability of mathematical problem solving, such as (1) understand the problem, (2) recheck the answer while all the student with low disposition mathematical ability could not fulfill all indicator of the ability of mathematical problem solving.
