Abstract

This research aims to describe common mistakes made by students in calculating fractional numbers, especially in comparing fractional numbers. For this reason, an analysis of the mistakes made by students is required. The subjects in this research were three students of SMP Muhammadiyah 1 Godean who were taken after fulfilling the requirements for selecting research subjects. Test and observation methods are the methods for collecting data. The data analysis technique used in this research is Newman's theory, of which there are 5 stages, namely: (1) reading stage, (2) understanding stage, (3) transformation stage, (4) process skills stage, and (5) Answer Writing Stage. This research shows that the errors made by students in general are: (1) Errors in reading and understanding questions, (2) Errors in reading mathematical comparison symbols, (3) Errors in changing the form of images presented to fractional numbers, and (4) Errors in calculating the LCM value between two denominators.

Abstract

This study aims to analyze the formative test items for the Mathematical Logic and Sets course in the Digital Innovation Program of the Mathematics Education Study Program, FKIP UAD in terms of classical test theory. This research is descriptive research. The analysis was carried out on 20 multiple choice test items which were tested on 51 students. The analysis was carried out on the difficulty and discrimination index and reliability with the help of the ITEMAN (Item and Test Analysis) package program. The results of the analysis of the difficulty index showed that of the 20 items, there were 6 items that were difficult and 14 items that were moderate. In terms of discrimination, 18 items had good discrimination index and only 2 items had poor discrimination index. One of the causes of low discrimination index is caused by items that are too difficult. From these results, further revisions were made to the items that did not meet the good criteria. Reliability estimation using the Cronbach Alpha formula shows that the measurement results obtained through this test are reliable.

Abstract

An innovative teaching material such as e-module were needed to assist students understanding the concept of mathematics. In this Research is develop an e-module using Realistic Mathematics Education approach in Linear Equation System Two Variables. Research method is using ADDIE model which consist of five stages, namely Analysis, Design, Development, Implementation, and Evaluation. The validators of this research were content and media experts, while the research subjects were students of 7th grades in Pleret Bantul Junior High School. The instruments used in data collection were interview and questionnaire. By the calculation results, the e-module was considered feasible by contents and media experts. From the validation of content expert get average of 3.56 with very good criteria, while from the media expert get 3.65 with very good criteria. The e-module was considered practical according to the students’ responses. In terms of practicality, average score of small class trial was 3.17 with good criteria, while average score of large class trial was 3.22 with good criteria. So, the average score based on content and media experts also student class trials get 3.40 with very good criteria. Therefore, smartphone-based e-module with realistic mathematics education approach on linear equation system with two variables material was feasible to use.Penelitian ini bertujuan untuk mengembangkan e-modul dengan berbasis Realistic Mathematics Education (RME) pada Sistem Persamaan Linier Dua Variabel. Metode penelitian yang digunakan adalah model ADDIE yang terdiri dari lima tahap, yaitu Analysis, Design, Development, Implementation, dan Evaluation. Validator penelitian ini yaitu ahli materi dan media serta subjek penelitian adalah peserta didik kelas VIII SMP Negeri 1 Pleret Bantul. Instrumen yang digunakan dalam pengumpulan data penelitian berupa wawancara dan angket. Berdasarkan hasil perhitungan, e-modul termasuk layak oleh ahli materi dan ahli media. Dari validasi ahli materi dan media mendapatkan kategori yang sama yaitu sangat baik dengan nilai rata-rata 3,56 dan 3,65. Berdasarkan uji kepada peserta didik e-modul termasuk praktis dengan kriteria baik pada uji coba kelas kecil dan besar dengan nilai 3,17 dan 3,22. Berdasarkan dari rata-rata gabungan ahli materi dan media serta uji coba peserta didik mencapai rata-rata skor 3,40 dengan kriteria sangat baik. Kesimpulannya e-modul berbasis smartphone dengan pendekatan Realistic Mathematics Education pada materi sistem persamaan linear dua variabel layak digunakan.

Abstract

This research was motivated by problems identified during the preliminary research at SMP Muhammadiyah 1 Godean through interviews with the mathematics teacher and the distribution of questionnaires to students. The information obtained indicated that mathematical problems in the form of story problems were difficult to understand and there was a lack of mathematical learning media that used a specific approach to help students understand mathematical problems. Therefore, this study aims to develop and evaluate the feasibility of an electronic student worksheet based on a constructivist approach using Liveworksheets for the topic of Systems of Linear Equations in Two Variables (SPLDV) for Grade VIII students. This research used a Research and Development (R&D) method using the ADDIE model. The research subjects were students of class VIII-D. The validation process was carried out by two validators, namely media and subject matters validators. After the validation assessment was completed, a trial was conducted, consisting of a small-scale trial and a large-scale trial. Based on data analysis, the research result indicate that electronic worksheet received a very good rating from both the subject matter expert with a score of 110 and the media expert with a score 89. Student responses were also categorized as good, with a score of 97.7 in the small group trial and 96.6 in the large group trial. Thus, the developed electronic worksheet is deemed feasible for use in mathematics learning.

Abstract

This study aimed to develop a contextual student worksheet integrated with Qur’anic values in the system of linear equations in two variables. The study evaluated the worksheet’s feasibility, the suitability of Qur’anic values, and described students’ perceptions of the contextual material. This research used the ADDIE model of research and development. Research instruments were adapted from previous studies and reviewed by experts before use. The research subjects were eighth-grade students at MBS Pleret. The developed worksheet included five activities that integrating Qur’anic values. Expert validation using using Ideal Assessment Criteria found the worksheet feasible. The material expert’s average score was 161, in the good category. The media expert’s average score was 144.5, in the very good category. Implementation in small classes with 10 students and large classes with 29 students received student responses of 113,5 and 121, categorized as good and very good. Additionally, the assessment of Qur’anic value suitability in the material scored 24.5 and 20.4 indicating a good category. Students responded positively to the contextual worksheet integrated with Qur’an value, with perceived understanding scores of 35.9 and 36.9, both falling within the good category. These findings, indicates that the developed worksheet is feasible and has the potential to support mathematics learning through contextual activities integrated with Qur’anic values.   Keywords: Student worksheet; Qur’anic Values; System of Linear Equation; Contextual
