Abstract

This study aims to analyze the implementation of transformative education in the Mathematics Education (Tadris Matematika) Study Program in producing Islamic, professional, and competitive mathematics educators. The sample in this research is Mathematics Education (Tadris Matematika) lecturers and students. Collecting data using observation, interviews, and documentation. The methods of data analysis used are reduction, display, and conclusion drawing and triangulation techniques. From this study, it was found that the implementation of transformative education in mathematics education (tadris matematika) study program was carried out by lecturers in producing Islamic, professional, and competitive mathematics educators. In producing Islamic educators, it is necessary to evaluate and improve again. In producing professional educators, the effort is still minimal, while the efforts of lecturers in producing competitive mathematics educators already exist through scientific writing competitions, but this has not had a good impact on producing competitive mathematics educators because most students are still insecure/lack of confidence in take part in competitions. The obstacles found are the lack of supporting infrastructure in professional development and the lack of self-confidence and motivation from students and lecturers. The contribution in this research is as an evaluation material for Mathematics Education (Tadris Matematika) lecturers, faculties in improving prospective Islamic, professional, and competitive mathematics educators in accordance with the vision and mission of the Mathematics Education (Tadris Matematika).

Abstract

The purpose of this study was to describe affective assessment in mathematics subjects using LMS media as a media to support learning activities between students and teachers in online learning. The subjects of this study were 214 students who were divided into five classes in class XI IPA SMA Negeri 1 Purbalingga. This research was conducted in July – September 2021. The data in this study were obtained from the results of filling out questionnaires related to affective assessment in online learning. The scale used to measure the affective aspect of the activities of an object is the Likert scale. The data analysis technique used descriptive statistical methods. The results showed that the implementation of the affective domain assessment in online learning through the Learning Management System (LMS) in the mathematics subjects of class XI science students at SMA Negeri 1 Purbalingga was running well. Teachers and students can already use the application as expected so that students can follow the learning well. With the LMS, it is easier for students to understand the material, get assignments and assessments and can interact and discuss with the teacher smoothly. In addition, students also remain highly motivated even though learning cannot be done face-to-face.

Abstract

In mathematics, there are two criteria for questions or problems, namely challenging and demanding procedures that are not routine in solving them. The problem is a situation where a person is able to realize the existence of a situation and admit that the situation requires action and resolution that is not easy. By using problem solving strategies, students can make a mathematical representation of the problem, which is one of the abilities in mathematics related to problem solving, reasoning, proof, and communication. Conversely, if we choose the right representation, it will allow us to reach an effective solution to the problem. Heuristic is a strategy used to find and solve a mathematical problem using solving steps. There are many types of heuristic strategies that can be used in learning mathematics to solve problems, but in this study, will be discussed strategies by Mathlin, namely The Analogy Approach, The Means-Ends Heuristic, and The Hill-Climbing Heuristic.

Abstract

The purpose of this study was to hone the nurturant effect of the value of the character of responsibility on students by integrating Islamic values in mathematics learning. This research is an experimental study using observations and interviews with 5 students of class VIII2 and teachers of SMPN 5 Langsa. Based on the results of the study, it was found that there was a development of the value of the character of responsibility which included a sense of responsibility in completing the tasks that had been given, awareness in helping to solve problems in the group, discipline, and awareness of serving punishment if violating the rules.

Abstract

The problem in this study is that students' self efficacy is still lacking in the learning process which has an impact on the final value of the economic mathematics course. This study aims to determine the effectiveness of the application of scaffolding on student self efficacy in the economic mathematics course of STKIP Kumala Lampung Metro. This research is an experimental research with one group pretest-posttest design. The population in this study were all students of Economic Education in the fourth semester of the 2020/2021 academic year, while the sample consisted of 30 students. The sampling technique used is saturated sampling. The data collection technique was done by using a questionnaire. In this study, prerequisite tests and data analysis processes, both from normality tests and hypothesis testing, use the help of SPSS data processing applications. The results obtained that the distribution is normal, then the t-test with a sig level of 5% obtained the results thitung (3,161) > ttabel (2,045) which means there is a difference between before and after the application of scaffolding on students' self efficacy. Furthermore, for the effect size test results obtained 0.577 which means it is included in the medium category. So it can be concluded that there is an effectiveness of the application of scaffolding on the self efficacy of students in the economics mathematics course.

Abstract

This study aims to determine the validity and effectiveness of interactive video learning media based on Power Director in the area of the triangle material. The research approach used is the Research and Development (RnD) approach with the ADDIE (Analyze, Design, Development, Implementation, Evaluation) development model. The subjects in this study were class X-TOT 1 (control class) and class X-TOT 2 (Experimental Class). Methods of data collection using questionnaires and tests. Questionnaires were used to obtain media validity data and tests were used to determine the effectiveness of using media. The results showed that the Power Director-based interactive video learning media was valid for use with a media validity value of 3.02 and a material validity value of 3.7. The results of the t-test calculation carried out obtained a value of 0.001 <0.05 which indicates that there is a significant difference between the control class and the experimental class in the use of Power Director-based learning media. So, Power Director-based interactive video learning media is effectively used because it can improve student learning outcomes in solving the area of the triangle problem.
