Development of Digital Teaching Material Based on Numeracy For 4th Class Primary School

Silvio Juliana Nabela — 2024-05-04

Indonesian students' mathematical literacy abilities are at a low level. Students have not been able to solve problems that require logical and applied thinking. So, teaching materials are needed that can facilitate critical thinking skills based on numeracy literacy which refers to 21st century learning by optimizing technology in learning. The teaching materials developed refer to several mathematical applications such as facts, operating principles, and problem solving in everyday life. The research method used in this research is Research and Development (R&D) with the ADDIE model consisting of Analysis, Design, Development, Implementation and Evaluation. The research results show that digital teaching materials are suitable for use based on validation results by material experts, media experts and language experts. Practical digital teaching materials are used based on the results of teacher and student response questionnaires.

Logical Thinking in Idealist and Rational Students

Lady Agustina — 2024-05-28

The purpose of this study is to describe students’ logical thinking based on Keirsey’s personality types, specifically the Idealist and Rational types, within the topic of social arithmetic. The research adopts a descriptive qualitative approach. Data collection involves three techniques: MBTI (Myers-Briggs Type Indicator) surveys, logical thinking written tests, and semi-structured interviews. The study participants consist of students from classes VII A, VII B, and VII C at SMP Muhammadiyah 9 Watukebo. The research subjects include four students: two with Idealist personality types and two with Rational personality types according to Keirsey’s classification. The findings indicate that none of the research subjects fully meet the three logical thinking indicators, which are grouped into six points. However, there is one indicator that all subjects were able to achieve: the first indicator related to coherence of logical thinking (point B), which involves expressing the general steps used in problem-solving. On the other hand, there are indicators that none of the research subjects were able to fulfill completely. These include the second indicator concerning argumentation ability (point A), which involves articulating the logical reasons for using general steps in problem-solving, and point C, which pertains to expressing the logical reasons behind the correct final answer. Among the research subjects, the subject who successfully fulfills the good logical thinking indicator is the second subject with a rational personality type according to Keirsey’s classification.

Students' Ability to Solve Story Problems on Systems of Linear Equations Using John Dewey's Approach

Suryanti Suryanti — 2024-05-30

Students can study everyday mathematics with a story problem. Through this problem, students gain critical thinking experience in solving problems. The ability of students to solve problems through John Dewey's approach is also seen to deepen students' mathematical concepts in three-variable linear equation systems. Problem solving with John Dewey's approach consists of five stages. This method of research uses a qualitative descriptive approach with three persons as the subject of the research, with good, sufficient, and less as the categories of ability. The results of the research showed the subject's ability to solve a story problem with the John Dewey approach. Four given questions showed that the subject with a category of good ability can solve two problems with clear mathematical concepts. Whereas the student with sufficient ability can only solve one problem with an obvious mathematical concept, However, the subject with less ability is only able to solve a problem until the stage of inventorying several solutions, which is the third stage of problem solving with the approach of John Dewey.

Nonny Zakiyanita Heldiana Ferly — 2024-05-30

Gestures that can help students communicate mathematically can be called gestures. This study aims to find out gestures that can help deaf students when solving math problems. This research uses a descriptive approach with a qualitative research type. The data sources used are test questions, observations, and interviews. This research was conducted at SLB ABC Balung with the subject of research as many as 2 SMALB students. The results of this study show that both subjects have their own characteristics when working on the problem. The first student prefers to count using movements assisted by scribbles, while the second student prefers to use hand gestures. In the first student, gestures occurred 38 times, consisting of iconic gestures 17 times, metaphorical gestures 10 times, and deictic gestures 11 times. In the second student, gestures occurred 40 times, consisting of iconic gestures 13 times, metaphorical gestures 5 times, and deictic gestures 22 times. Based on the results of this study, the gesture most often used when deaf students solve the problem is the deictic gesture, which occurs 33 times, and the gesture that appears the least is the metaphorical gesture, which occurs 15 times.

Application of Division Counting Machine Media for Deaf Students in Division Operation Material

Desi Amalia Romadona — 2024-05-30

Media is an effective tool used by teachers to support learning to convey the content of teaching materials. This study aims to determine the application of “division calculation machine” media for deaf students in division operation material. This research uses a descriptive approach with qualitative research. The data sources used are test questions, observation, interviews, and documentation. This research was conducted at SLB ABC Balung with the research subjects as many as 3 high school deaf students. The results of this study by applying the division calculation machine media used to solve division problems can help deaf students to understand the division operation material. Counting using the media “Division Counting Machine” can make it easier for students to count and make counting faster than counting manually although there is 1 student who says it is faster to use the manual than using the media but the student prefers to use the media because there is no need to count and only move the ice cream sticks. Based on this research, the media can make it easier for students to learn division and the media as a facilitator in the learning process in class.

Development of a GeoGebra-Assisted Transformation Geometry Textbook

Restu Ria Wantika — 2024-05-30

The transformation geometry course is a mandatory course that studies the basic concepts of transformation geometry, including translation, reflection, rotation, dilation, and transformation composition. Transformation geometry courses cannot be separated from the activity of deductively deriving concepts, theorems and algorithms, so more skills are needed so that students can understand this course easily. Therefore, the transformation geometry course requires good and effective teaching materials which can encourage students to actively interact with each other and be able to understand the material effectively, namely in the form of textbooks. The method stages carried out in this research are needs analysis, preparation of textbooks, expert validation, revision of textbooks, trials and giving questionnaires and evaluation. The results of the student response questionnaire revealed that 80% of students stated that they strongly agreed with the use of this Transformational Geometry textbook and the results of student understanding were good, so the textbook developed was valid, practical and effective.
