Abstract

Corona Virus Disease 2019 (Covid-19) has disrupted conventional learning process. Therefore we need a solution to The challenge. Online learning is one alternative that can overcome the challenge. So this research was conducted to know and analyze students' learning results through online learning in mathematics with the subject of the Two-Variable Inequality System (SPtDV) class X MIPA 1. The method in this study is the descriptive method with a quantitative approach. The instrument used was the test instrument on the SPtDV material with a total of 5 essay questions. The research sample was 14 students of class X MIPA 1 one of the public high schools in Soppeng Regency. The results of this study were four students with high scores, six students with moderate grades, and four students with low scores. Achievement of the lowest percentage of material indicators according to the Level of Ability to Answer the Problems Correctly of Students in a row from high, medium, low, namely solving problems in the area of the settlement set on the SPtDV material. Overall, the achievement of student learning results got a good predicate.

Abstract

This study aims to describe the types of student errors and the factors that cause errors in class XII MIPA 1 SMA Negeri 5 Soppeng in solving math problems on statistics. This research is qualitative research using a descriptive research methodology approach. Data collection was carried out using written tests and interviews. The subjects in this study were 31 students of class XII MIPA 1 SMA Negeri 5 Soppeng taken by purposive sampling. The types of student error were classified according to the Newman procedure. The results of this study indicate that in solving mathematical problems, the research subjects make types of errors; reading errors, comprehension errors, transformation errors, process skills errors, and encoding errors. The factors that cause student errors are poor network connection in looking for references to work on questions, unfamiliarity with online learning, lack of understanding of statistics submitted online, difficulty in the calculation part, lack of ability or not being used to writing things that are known and things those who are asked in the questions correctly, lack of practice working on practice questions related to statistics, do not like maths lessons, are in a hurry to work on the completion process. The solution to avoid or minimize the occurrence of these errors is to look for appropriate learning methods, look for references via the internet or from YouTube videos, students are actively practicing working on problem-solving types, practicing answering.

Abstract

This study aims to analyze the errors of class X SMA students on linear program material. The method applied is the qualitative description method. Purposive sampling was implemented in this study, and the participants were 30 students from class X MIA SMAN 5 Tapung. The types of errors analyzed are based on Nasution's theory, which states that there are three types of errors: conceptual errors, procedural errors, and computational errors. The test questions are given in the form of 7 description questions. The results of the analysis of student answers along with the analysis of interviews, errors in calculations occur because students are not careful in calculating and entering numbers into the formula. Therefore only 8 students whose scores exceed the standard score of 70. Based on the results of the analysis of student answers, it can be concluded that, students' errors in solving linear program questions are in conceptual errors where students do not understand the implied meaning of the questions; procedural and computational errors where students are not able to carry out the procedures or steps that will be used to solve the problems, do not know the arithmetic operations that will be used to solve the problems and do not write down the final results according to the procedures or steps applied.

Abstract

The inability of students to solve problems will result in errors in solving them. This study aims to describe students' errors in the circle equation material and the factors that cause errors in class XI SMKN 3 Pekanbaru and solve math problems related to circle equation material. This research is descriptive research. The subjects in this study were 36 students of class XI SMKN 3 Pekanbaru. The data collection technique was carried out by means of a learning outcome test which consisted of instruments describing the circle equation. As for the percentage of errors made by students, namely students who made fact errors as much as 29% due to the lack of accuracy of the students in writing the symbols of the circle equation, the students made 23% misconceptions because the students did not understand the questions well so that students are random in determining the formula used to solve the problem, students made a principle error of 16% because the students were careless in determining the formula to solve the questions, students make operating errors as much as 32% because students are not careful in doing algebraic operations and are in a hurry to work on the problem.

Abstract

Teachers must have teaching skills and create a comfortable, joyful, relax, and serious learning atmosphere. Therefore, teachers must understand the learning process, must be aware of the learners’ psychologies, and capable of developing the learners’ interest so they have greater spirits to learn. From various problems of teaching mathematics, the teacher's position is the center of the problem. Teachers as motivators, educators, and supervisors have important roles to direct learners to be capable and to actualize them in real life through the school lessons. There are several factors of difficulties experienced by mathematics teachers in implementing learning at SMAN 2 Tambang. This research aims to determine the difficulties experienced by mathematics teachers in implementing learning. This type of writing uses a descriptive qualitative approach. The subjects of this research were teachers at SMAN 2 Tambang. Data collection techniques used interviews and questionnaires. It could be concluded that the most common difficulty was determining the learning media and learning process planning. The cause was the limitation of facilities, infrastructures, and unfordable media by the learners. On the other hand, the next difficulties were due to the large number of learners that could not be accommodated in a small classroom.

Abstract

Improving the quality of learning for candidates of prospective mathematics teachers is needed, so prospective educators can improve the quality of learning and education in Indonesia. Moreover, PPL students (Field Experience Program) is still very minimal knowledge about curriculum 2013. This research aims to describe the knowledge of prospective mathematics teachers in the preparation of a Lesson Plan (RPP) in the curriculum 2013. Techniques used in data collection include (1) documentation in the form of a collection of lesson plans (RPP) and (2) structured interviews. The knowledge of mathematics teacher candidates about the curriculum 2013 in the preparation of RPP, shows that Subject 2 is higher than Subject 1. Subject 1 with an average of 3.45, and Subject 2 with 3.57. The results of the analysis of the assessment conducted show that the knowledge of mathematics teacher candidates about the Curriculum 2013 is very good, there are still some inaccurate understandings, such as knowledge of the relationship between curriculum tools, compatibility of KD and components in RPP, sources and media to learn knowledge about the context in preparation of perceptions and motivation and the link between learning activities and learning models.
