This study aims to analyze the differences and also the relationship between attitudes and self-efficacy of students in science lessons. This research is important because in science lessons the teacher must know the attitudes and self-efficacy of students because they affect the learning process. This type of research is quantitative with comparative type. The number of respondents used as a sample is 74 students. The data collection technique used simple random sampling. The results of the study using the T test were that there were significant differences in the attitudes and self-efficacy of students in science lessons, both female students and male students. The results of the correlation test between students' attitudes and self-efficacy towards science subjects in grade 8A showed that the two variables (attitude and self-efficacy) were related. And the results of the correlation test in class 8B showed that the two variables (attitude and self-efficacy) were related. The urgency of this research is that teachers can find out the differences in attitudes and self-efficacy between male and female students. The novelty of this research compared to previous research is that it uses Attitude and self-efficacy variables, with different indicators from previous research.

Computational Difficulty

Although solving polynomial equations is important in mathematics, most high school students can solve only linear and quadratic equations. This is because the methods for solving cubic and quartic equations are difficult, and no general methods of solution are available for equations of degree higher than four. However, numerical methods can be used to approximate the real solutions of polynomial equations of any degree. Because they involve a great deal of computation they have not traditionally been taught in the schools. Now that most students have access to calculators and computers, this computational difficulty is easily overcome.

The first 50 stimuli from the K-R list, two personality tests (the MCI and the GZTS), and 26 verbal ability paper-and-pencil tests were given to a large number of senior high school students. Two response categories for the K-R, opposites and non-opposite primaries, and the personality tests had low correlations, most of which did not differ significantly from zero. This finding is consistent with that of previous investigators. The correlations between the K-R response classes and the 26 verbal tests, however, yielded different results. The non-opposite primaries tended to exhibit low positive (significant) correlations with the verbal tests, whereas the opposite scores showed essentially zero correlations with these same tests. These findings were interpreted as further supporting the contention that commonality scores do not represent a unitary verbal habit.

Thinking Errors

In solving problems, students often experience thinking errors, one of which is pseudo thinking. Pseudo thinking is errors of thinking, wherein the individual process of solving a problem it is not the result of real thinking. Mistakes of thinking like this need attention and must be immediately addressed so as not to impact on students' understanding of the next mathematical concept. This study is a descriptive exploratory with a qualitative approach, aims to describe and explore the pseudo thinking profile of high school students with different mathematical abilities. The subjects in this study consisted of, one with high mathematical ability, one with moderate mathematical ability, and one with low mathematical ability. Data collection techniques were carry out by giving mathematics ability tests (TKM) and interviews. Data analysis was perform based on pseudo-thinking indicators (pseudo-right thinking and pseudo-wrong thinking). It was found that, subjects with high mathematical ability tend to be able to experience pseudo-right thinking and pseudo-wrong thinking. Subjects with moderate mathematical ability tend to be able to experience pseudo-right thinking, while subjects with low mathematical ability tend to be able to experience pseudo-wrong thinking.aKeywords: thinking mistakes, pseudo thinking, problem-solving, mathematical ability

This study aims to describe students' reflective thinking in solving algebraic problems with different mathematical abilities. This study used reflective thinking components by Surbeck, Han, and Moyer, including reacting, elaborating, and contemplating. This study was descriptive qualitative research that used a qualitative approach. The instruments in this study were mathematical ability tests, mathematical problem-solving tests, and interview guidelines. This study was conducted by selecting three subjects from 31 students of SMAN 1 Pacet with female gender who have high, medium, and low mathematical abilities. This study's results were at the reacting stage; the three students analyzed what was known and asked according to the information provided, analyzed the relationship between what was known and asked, and reasons. At the elaborating stage, the three students were able to analyze the theory used. High and low-ability students have encountered similar questions. Medium ability students admitted that they had never met similar questions but examined the differences. High and medium-ability students explain the results obtained in detail at the contemplating stage, check their results, and make conclusions. Low ability students only explain part of the solution because they cannot find the solution. They try to correct their mistakes but give up, so they do not make conclusions. For low-ability students, the teacher can provide practice questions that trigger reflective thinking to solve math problems correctly and improve their weaknesses. Keywords: reflective thinking, mathematics problems, high school algebra, mathematical ability.
