Abstract

The background of this research is, there is no learning model that can optimally support critical thinking skills, so it takes an innovative learning model. In this case, the researchers used web helped to guide discovery learning model to improve the critical thinking skills of the student in class X SMAN 4 Praya in academic year 2019/2020. This study aimed to find an effect of web assisted guided discovery learning on trigonometry material to critical thinking ability of the student in class X SMAN 4 Praya in academic year 2019/2020. This study use a quantitative research approach to the type of experimental research. In this experiment the researchers used a quasi-experimental, and uses two classes as a research, the experimental class and control class. The population of this research is all the student in class X SMAN 4 Praya and and choose two class as a sample class that is X MIPA 5 as a experimental class and X MIPA 3 as control class. Student in experimental class used web assisted guided discovery learning model and in control class used guided discovery without web assisted. The result of the research showed that the average of critical thinking ability in the experimental class is better than control class which is in the experimental class is in the less effective category and control class in ineffective category.

Abstract

The sets concept that still be the problems for students of class VII at SMPN 15 Mataram. The average of daily test score on the material sets of students of class VII is 60.45 with 38.81% of classical completeness. It means that most of seventh grade students make mistakes in order to complete the daily test questions related to the concept of the sets. The aim of this research is to identify an error to solve the question of sets by students of seventh grade at SMPN 15 Mataram in academic year 2017/2018. In addition, this study is conducted to determine the level of error to solve about the sets material, and to see the relationship of every types of error with the overall error in order to solve the question of sets. The type of this research is descriptive research of quantitative type. The data analysis technique used in this research is statistical descriptive data analysis and correlation analysis of pearson product moment test. The result of the research shows that the dominant error of students is the type of error using theorem, definition, or formula with error percentage 56.19%. Based on the basic competence of the sets material, students make the most mistake on basic competence 4.5 with percentage of error of 61.71%. In addition, the type of error using the data is stronger relation with a correlation coefficient 0.89 which is very strong category.

Abstract

This study aims to describe students' mathematical investigation abilities on number pattern material in terms of gender differences. This type of research is descriptive qualitative and quantitative with the instruments used in the form of mathematical investigation test questions, and interview guidelines. Subject selection using purposive sampling, which is based on the teacher's considerations. The subjects in this study were students of class IX-A of SMPN 1 Mataram for the academic year 2021/2022, totaling 32 students. The test results were analyzed for each item based on the ability of mathematical investigation including specializing, conjecturing, generalizing and justifying. The results showed that the mathematical investigation ability of female students as many as 10 students (62.5%) were able to work on the four stages, the three-stage category was 2 students (12.5%), the two-stage category was 3 students (18.75%), and one-stage category as many as 1 student (6.25%). While the mathematical investigation ability of male students as many as 8 students (50%) were able to work on all four stages, the three-stage category was 3 students (18.75%), the two-stage category was 5 students (31.25%). In this study, interviews were conducted with 6 students from each representative of each criterion of the mathematical investigation ability test results, namely 3 male students and 3 female students. The difference between male and female students lies in the generalizing and justifying stage where female students complete neatly, thoroughly and test the general pattern for the special case they are working on while the male students complete in a short way.

Abstract

This study aims to know the relationship between anxiety in the examination with the study result of 2020 mathematics education students of Mataram University. This study is correlational research. The data is analyzed using descriptive analysis with a quantitative approach. The population in the study is 136 mathematics education students, while the sample is 53. Sampling retrieval techniques using sampling samples. Data retrieval with an anxious instrument facing the exam and archivist’s final grades for student results. The result of this study is that anxiety facing a student’s exam fall within a moderate category and students’ learning result fall into the sufficient category. Based on the result of the correlation test, a coefficient correlation value of r = -0,112 with a count of -0,799, t table of 0,271 at a significant 5 %, so -0,799 < 0,271 means there is no significant relationship between the anxiety of facing a test and the study of the student academic year 2020/2021. Whereas anxiety in the face of a test contributes to resulting of 1,26%. The remaining 98,74% are determined by other factors not studied in this study.

Abstract

This research is an exploratory descriptive with a descriptive quantitative approach or mix-method which aims to analyze the thinking processes of pre-service mathematics students based on the SOLO taxonomy in solving differential equation problems. The subjects were 86 pre-service mathematics students of the fifth semester of the mathematics education study program who were selected using the purposive sampling technique. Meanwhile, data were collected using problem-solving tests and interviews and then analyzed using descriptive and qualitative statistics with the following stages: (1) transcribing test and interview data, (2) coding segmentation, (3) analyzing student thinking processes in solving differential equation problems, and (4) drawing conclusions. The results showed that pre-service mathematics students' thinking levels were at the pre-structural level (6.98%), uni-structural (25.58%), multi-structural (60.47%), and extended abstract (6.98). Meanwhile, there is no one at the relational level in solving the problem. These results indicate that students need to be well supported and facilitated in problem-solving to achieve higher levels of thinking, such as the relational and extended abstract levels.

Abstract

Learning media have a contribution to the teaching and learning process, not only helping teachers deliver lessons but also providing added value in learning. One of the media that can be used as a solution as an interesting learning medium is a computer-based tutorial media of mathematics. This study aims at producing a practical computer-based tutorial media of mathematics. The subject of the study is the 30 students of IX-4 class of SMPN 1 Keruak, in which it is categorized as research and development by using the model ADDIE from Brunch. Furthermore, ADDIE is the acronym for analyze, design, development, implementation, and evaluation. The instrument used in collecting the data consists of a teacher-student practicality instrument. Based on the media, the assessment for the testing of practicality is in the category "very valid” for the teachers and students with 89% for teacher practitioners and 89 3% for student practitioners. Based on the result, it can be concluded that a computer-based tutorial media of mathematical learning that has been developed is feasible to use.
