Abstract

The study aimed to improve the skills of students mathematical connections and self-efficacy for grade VII D of SMP N 3 Sidareja in the 2018/2019 academic year through CORE (Connecting, Organizing, Reflecting, and Extending) learning on the topic of triangles and rectangles. The study was conducted in three cycles and each cycle consisted of planning, action, observation, evaluation, and reflection stages. The instrument used was a description test to measure the skills of students' mathematical connections given at the end of each cycle, while the instrument used to measure self-efficacy was self-efficacy questionnaire. Based on the findings, each cycle obtained an improvement. The first cycle obtained mathematical connection skills by an average of 64.74, 77.24 in the second cycle, and 81.41 in the third cycle. The average results of students self-efficacy in grade VII D in the first the cycle was 69.67, 76.05 in the second cycle, and 79.85 in the third cycle. Based on the data above, it can be drawn that there was an improvement of students' mathematical connection skills and self-efficacy from cycle I to cycle II and from cycle II to cycle III through CORE learning (Connecting, Organizing, Reflecting, and Extending).

Abstract

This research aims to describe the level of understanding the concept and critical thinking in resolving trigonometric equations using graphs. Tests and interviews were conducted to search for data and study more in the ability to understand the concepts and critical thinking skills that students have in resolving trigonometric equations using graphs. The test given to the students is a test of the explanation with the subject of his research is a class XI student. The subject selection of six students is based on the category of ability and daily replay value of the student in trigonometric materials. The six students are each – two students of high, medium and low categories. The results showed that the ability level of understanding students ' concepts in determining the set of solving trigonomic equations using graphs, gained students understanding the concept of high and moderate levels. Students with a high level of understanding are able to fulfill all indicators – an indicator of concept comprehension. Students with the level of understanding of concepts are also meeting the indicators of understanding the concept but less appropriate, which has not been able to identify the properties of a concept. Students are also less able to classify objects based on the requirements that make up the concept. The level of students ' critical thinking ability to determine the set of solving trigonomic equations using graphs obtained by the subject of students critical thinking moderate and low levels. Students with critical thinking levels are not yet able to meet interpretation indicators, i.e. students have not been able to understand and write the answer to the problem given. Students with critical thinking levels are also underprivileged to meet critical indicators of inference. Students with critical thinking levels are less able to draw conclusions, i.e. less capable of providing the right reasons for student work. Students with critical thinking levels are low, not yet capable of meeting critical thinking indicators in determining the set solving trigonometric equations using graphs. Students have not been able to meet all indicators of critical thinking ability.

Abstract

This research aimed at discovering the validity and effectiveness of the interactive media of "Venn Gram" to improve the conceptual understanding of the set operations. This research was a development research (research and development). The research subjects were the students of 7th grade who consisted of nine students. The data collection techniques were in the form of a validation questionnaire and test. The subjects were in the form of pre-test and post-test questions which later the answer sheets were used as an increase of students' conceptual understanding before and after using the media. The validation questionnaire results showed that 84% of the media were very valid, 83% of the material was very valid, and 82% of the test questions were very valid. The test results found that seven students experienced an increase in the pre-test and post-test scores. Meanwhile, two other students experienced a decrease. The results of students who had increased showed that the ability of students in understanding the concept of set operations was included in the high criteria before and after using the media. The media of the Venn Gram can be used to improve the conceptual understanding of set operations.

Abstract

Perception is an individual's ability to respond, interpret, and distinguish a view of any information to a stimulus. So the aims of this study was to find out: (1) students' perceptions of the use of an equation editor in writing mathematical notation as assignments for calculus class I papers, (2) students' perceptions of writing calculus I paper assignments using the manual method (handwriting). The research subjects consisted of 16 students majoring in Extension Informatics Engineering (afternoon class) Semester I. The type of research was descriptive qualitative. Data collection techniques are interviews. The analysis stage is to analyze the results of the interviews. The results of the study concluded that: (1) 11 (eleven) students agreed to use the equation editor in writing calculus I paper assignments,the rest were still confused about the use of the equation editor; and (2) all students do not agree if the paper is written using the manual method (handwriting) because the results are not neat and take a long time.

Abstract

At this time, many students think that learning mathematics is difficult to understand. While Powtoon animation video-based mathematics learning media is still rarely applied, students feel bored. They do not understand the concept of material when the learning process uses the lecture method. The purpose of this study was to determine the effectiveness of using Powtoon animation video-based mathematics learning media on the material for the Two-Variable Linear Equation System in Junior High School. The type of approach used is a pre-experimental quantitative approach by applying a one-group pretest-posttest design. The research population includes all students of class VII-A at SMP NEGERI 1 NGIMBANG for the academic year 2020/2021, with 32 students consisting of 8 male students and 24 female students. Data collection techniques using tests and questionnaire sheets. While the data analysis technique used is normalized gain. The data obtained show differences in students' test results using the Powtoon animated video and before using the Powtoon animated video. The difference was seen from the average score of the students' test results before using the media of 36.41 and after using the media of 92.58. In addition, the research results from the N-Gain Test results show that the use of Powtoon animation video media is effective in learning mathematics. It is evidenced-based on the results of the expert test and media validation by obtaining 85% and 83.75%, which means that it belongs to the outstanding category. In comparison, the results of the student response questionnaire of 81.29% belong to the outstanding category. Students' test results get an average of 0.88% from the n-gain, which shows a high classification. This study indicates that Powtoon animation video media is effective in learning mathematics compared to learning that only uses the lecture method. 29% of it belongs to the outstanding category, then through the test results, students get an average of 0.88%, which is obtained from the n-gain, which means it shows a high classification.

Abstract

One of the mathematical abilities that students must master in order to learn mathematics is the ability to understand concepts, since it can affect the quality of learning and academic accomplishment of students. If the student's idea understanding is good, he or she will be able to solve the problem using the procedure. As a result, the goal of this study is to determine and describe students' grasp of mathematical ideas in linear programming material. This study's instrument is a set of learning outcomes test questions that refer to indications of concept comprehension. A qualitative research design is used in this study. Data reduction, data presentation, and generating conclusions were used to examine the data in this study. According to the findings, 33 students were able to meet the indicators of the ability to understand mathematical concepts by providing examples and non-examples, which received the highest percentage value, followed by indicators presenting concepts in various forms of mathematical representation, which received the second highest percentage value.
