Abstract

The ability to solve problems is one of the abilities that mathematics students must have in order to become a capable problem solver. This study aims to describe the ability of the fifth semester students of the Mathematics Education Study Program, Mathematics and Natural Sciences Education Department, Faculty of Mathematics and Natural Sciences, University of Palangka Raya in solving problems on the random variable material and the distribution of opportunities. The research instrument consisted of 2 questions consisting of one routine question and one non-routine question. The subjects in this study were students of the Mathematics Education Department of Mathematics and Natural Sciences Education, Faculty of Teacher Training and Education, University of Palangka Raya, who programmed the Mathematics Statistics I course in the fifth semester of class B academic year 2020/2021 as many as 26 students. The results showed that only 8 people (30.8%) were able to complete routine questions perfectly and 18 people (69.2%) were less than perfect. Meanwhile, for non-routine questions, only 1 person or 3.8% were able to answer correctly and 96.2% were unable to complete the questions given. This shows that the ability of students to solve random variable problems and the distribution of opportunities in the Covid-19 era in general for routine questions is still low and non-routine is very low, which indicates that students' lack of understanding and mastery of the concepts that have been conveyed through online learning

Abstract

This research was motivated by the SMA Negeri 1 Kasongan school which never identified student errors in solving trigonometry problems. This type of research is descriptive with quantitative and qualitative approaches. This research was conducted in the even semester of the 2021/2022 academic year. Subjects are students of class X SMA Negeri 1 Kasongan for the academic year 2021/2022. Data collection techniques used are tests and interviews conducted face-to-face at school. The research instrument used was a test sheet consisting of 3 items of description. The test questions in this study were reviewed by three raters. The types of errors made by students in solving trigonometry problems are: Fact Error (A1) most students miswrite the term (name) or symbol/notation used in trigonometry material, Concept Error (A2) students do not understand abstract ideas in trigonometry material so that students cannot solve trigonometry problems, and Operational Errors (A3) students work on problems not according to the correct problem solving procedure, Principle Errors (A4) students do not understand the relationship between several facts and concepts and theorems associated with relations or operations so that errors occur in the completion process and result. The factors that cause students to make mistakes in solving trigonometry problems in the sub-material of trigonometry comparisons in right triangles, namely: Knowledge, in the form of lack of facts, truths or information obtained by students regarding the material that has been studied from simple to difficult material. Understanding, in the form of a lack of students' ability to understand the content of the material. Application, in the form of a student's lack of ability to apply the material that has been learned in new situations and involves the use of rules or principles.

Abstract

Mathematical literacy or usually known as numeracy is an interesting educational topic because it is one of the competency standard criteria for graduates. The purpose of this research is to describe students' mathematical literacy in working on contextual mathematic problems. This research method is descriptive qualitative research which the instruments are tests of mathematical literacy skills and interviews. This research was conducted on 3rd semester mathematics education students. Result of this research is description of the subjects that has the best mathematical literacy among the others. Students who have good mathematical literacy when working on contextual problems will identify and create the variables needed for the initial step of solving the problem. Then he can use concepts, facts, procedures, and mathematical reasoning by using the variables he has created and connecting them with the his knowledge. Finally he also interprets, applies, and evaluates the results mathematically by providing conclusions from the solutions he has worked on.
