The problem solving skills are part of learning mathematics and an important component of 21st century education. But students often experience success doing it. The purpose of this study was to determine the relationship between mathematical abilities, self-efficacy and problem solving abilities. This is a result of low mathematical abilities and self-efficacy. The research was a survey. Samples were randomly selected as many as 135 students from whole high school students in the Kota Bengkulu. The research instruments were a self-efficacy questionnaire, a mathematical ability test and a mathematical problem solving test. Data was analyzed using structural equation modeling. We used LISREL 8.8 to test the structural model. The results, there is a positive direct effect of mathematics ability on problem solving abilities; there is a positive direct effect of self-efficacy on problem solving abilities, and there is a positive direct effect of mathematics ability on self-efficacy.

The objective of this study was determined the relationship between emotional intelligence and self-efficacy of students in dealing with the National Examination. The population of the study was all students in one of senior high school in Bengkulu. Number of samples in this study is 100 students for Class XI. The sample was selected by the random technique. Data collection was carried out using the instruments of questionnaire to measure students' anxiety and test of mathematics understanding to measure students' cognitive level of mathematics understanding. Data were analyzed by using the Path Analysis. The results of the study were that the emotional intelligence has a direct positive effect on the National Mathematics Examination. Also, the self-efficacy has a direct positive effect on the National Mathematics Examination. Finally, the emotional intelligence of teachers has a direct positive effect on the self-efficacy of high school students.

Mathematics is a compulsory subject in all of Indonesian high school. Problem solving ability is a competency that must be possessed in learning mathematics. The purpose of this study was to examine the variables that affect the ability to solve mathematical problems. These variables are self confidence, self efficacy, emotional intelligence, and the ability to understand concepts. This is a survey research, with a sample of 100 people. The sample was selected by simple random technique from all high school students in Bengkulu City. There are five instruments of this research, namely a test of mathematical problem-solving ability, a concept comprehension ability test, and three questionnaires for self confidence, self efficacy, as well as an emotional intelligence questionnaire. Research data were analyzed through path analysis using SPSS and the Lisrel Application Program. The results of this study were the variables of self confidence, self efficacy, emotional intelligence, and the ability to understand concepts have a direct positive effect on the ability to solve mathematical problems. From this research, we conclude that the ability to solve mathematical problems through self-confidence, self-efficacy, emotional intelligence, and the ability to understand concepts students were in a good category.
