Abstract

This research is motivated by the large number of students who experience learning barriers on trigonometry material. The obstacles that often occur in students when solving questions that are not routine such as questions in the form of stories. The purpose of this study is to analyze the epistemological obstacle of high school students on trigonometry material. The method of this research is a descriptive qualitative method with the subject of the study being students of class XI in one of the high schools in West Bandung with 27 students. The instrument used was a test in the form of a description of trigonometric material and interview guidelines. Data analysis techniques used are: Data reduction, data presentation and data verification. The results and discussion of this study is that the epistemological obstacle of high school students on trigonometry material occurs because of the limitations of students when solving non-routine problems. When students are given unusual questions, which are questions in the form of stories, students experience learning obstacles and tend to be unable to solve problems by completing. Students who are given ordinary or easy problems will make students difficult in working on questions in the form of stories. Students should be given problems in the form of problem solving, so students can think critically and will not have difficulties when given questions in the form of stories or problem solving.

Abstract

The Covid-19 pandemic makes the learning/lecturing process carried out online to break the chain of spreading the coronavirus. One of the models that can be applied to online learning is blended learning by combining LMS and video conferences. The purpose of this study was to see how effective the use of blended learning is in improving student academic abilities through Schoology during the COVID-19 pandemic. The research design used the Non-Equivalent Control Group Design for 2 treatments (cycles), before and after the midterm exam. Techniques for data analysis using Normality-Gain Test (N-gain) and T-Test for two groups of independent samples. The N-gain value in the experimental class was 43.57% in the medium category, while in the control class the N-gain value was 4.55% in the low category. Based on the results of the t-test, it was obtained that the t-count value was 8.8367 and the t-table value was 2.030, because t-count > t-table there was a significant difference between the experimental class and the control class. So that the application of the blended learning model using Schoology can improve students' academic skills.

Abstract

This study aims to describe the mistakes made by students of grade IX Middle School. As well as analyzing the factors that cause students to mistake in completing the material on flat side spaces in junior high school students in Cimahi City. The method used in this research is descriptive qualitative. The sample taken for this study was 10 students of class IX in one junior high school in Cimahi City. The test instrument was given as many as 5 items. Based on the results of data analysis, it can be concluded that there are errors in solving the problem of getting up the flat side space, namely: (1) not understanding the basic concept of building a flat side space; (2) lack of understanding of questions or lack of thoroughness in reading problems so students' answers are incomplete; (3) lack of mastery of the principle or conceptual relationship between flat figures (prerequisites regarding the Pythagorean theorem); (4) don't memorize the formula; (5) lack of precision in the calculation process. And this shows that grade IX students in Cimahi City are still low in solving problems in the material to build flat side spaces.

Abstract

This study aims to find out the difficulties of junior high school students in working on descriptive questions on social arithmetic material and to analyze the factors. The subjects of this study were 26 students of class VIII SMP Buana Panca Bakti Cianjur totaling 26 people in the 2019-2020 school year. Data collection in this study was conducted by means of tests, interviews and documentation. Before the interview, a math test was conducted with 5 questions of social arithmetic material. After the tests and interviews are carried out, the results of the tests and interviews are analyzed and taken from the difficulties the students experience when working on social arithmetic questions. The data analysis techniques used in this study were: (1) data reduction, by selecting the main things and focusing the important things, (2) data presentation, presenting the data on student work, (3) drawing conclusions. The results showed that the students' difficulties when solving social arithmetic problems were difficulties in understanding the problems because social arithmetic problems were in the form of story problems, difficulties in mathematical models and difficulties in the process or steps of completion. The factors that cause students' difficulties because students are lazy to read the questions, it is difficult to digest the words and the meaning of the questions, students are less interested in learning mathematics, and students do not understand the arithmetic operation well.
