Abstract

Inequality involving absolute values ​​is an important course material because it is not only studied by mathematics education students but also by mechanical engineering students. In the process of solving inequalities, an absolute value is very reasonable when various errors occur. One theory of error is Kastolan. The identity of Kastolan's theory of errors is in the form of procedural, conceptual, and technical errors. The general purpose of this study was to determine student errors in solving inequalities involving absolute values ​​based on Kastolan's theory of errors and the form of the errors. This research method uses a qualitative research approach with the type of case study. The instruments in this study were: the main instrument and the supporting instrument. The data analysis technique used an interactive analysis model by Milles and Huberman. The conclusion of this study is the student's error in solving inequality problems involving absolute values ​​based on the Kastolan error theory and the form of the error. Conceptual errors in the form of errors in working without using theorems, laws, or formulas, errors in applying formulas, and incorrect problem-solving errors (having errors in determining the sign of inequality, errors in determining the intersection of two inequality conditions, and errors in drawing conclusions or Sets of completion). In addition, the type of technical error with the form of error is a counting error

Abstract

The mindset of learning outcomes that most ordinary people know is only limited to the values ​​of the tests that have been carried out. So it still happens that teachers only focus on learning outcomes in the cognitive domain. Whereas the distribution of learning outcomes has 3 domains, namely cognitive, affective, and psychomotor. This research is a quantitative research with correlation technique. The population in this study were all grade VIII students of SMP Negeri 01 Kotabumi for the academic year 2020/2021, totaling 317 students. The sample of this study amounted to 79 students. The sampling technique used a proportionate stratified random sampling technique. The learning attitude instrument uses a questionnaire/questionnaire. Meanwhile, the learning outcomes instrument used a multiple choice test. Hypothesis test using Product Moment Correlation. For the correlation analysis of learning attitudes and learning outcomes, it produces a correlation coefficient (r_xy) of 0.2341 and r_(table(79)(0.05)) of 0.2210. This shows that there is a correlation (relationship) of learning attitudes (affective learning outcomes) and mathematics learning outcomes (cognitive domains).
