This research was conducted to determine whether there is an influence of TPACK, ICT, HOTS, and 4C on students' understanding of mathematical concepts. This study used a quasi-experimental design involving two sample classes: an experimental class and a control class. The research instruments included observation sheets to assess the implementation of teaching activities by the teacher and student engagement during the learning process, as well as a test sheet to measure students' understanding of mathematical concepts. The data analysis techniques used were descriptive analysis to describe teacher and student activities during the learning process and to determine the categories of students' understanding of mathematical concepts, as well as inferential analysis to test the research hypothesis. The results of this study indicated that: (1) the percentage of teacher activity implementation using TPACK, ICT, HOTS, and 4C had an average of 87.5%; (2) the percentage of student activity in improving mathematical concept understanding with the application of TPACK, ICT, HOTS, and 4C had an average of 82%; and (3) based on the hypothesis test, it can be indicated that there is a significant difference in the average mathematical concept understanding of students. Therefore, it can be concluded that TPACK, ICT, HOTS, and 4C have an influence on students' understanding of mathematical concepts

Learning Videos and Geogebra: Do They Really Help Students Solve Their Answers?

Agustina Setyaningrum — 2025-01-31

Multimedia is a combination of various media elements, such as text, images, audio, video, and animation used by teachers to deliver teaching materials effectively and innovatively. There are various types of interactive multimedia that can be used, one of which is that teachers often involve videos and GeoGebra to help students learn mathematics. In practice, this assistance often makes students take a longer path to achieve learning goals. This study provides another perspective to determine the implications of learning videos and GeoGebra in completing answers that help students. With a descriptive method, this study took students as its subjects whose results were analyzed qualitatively using data descriptions, data reduction and presentation of conclusions. It turns out that videos are less able to help students complete their answers and GeoGebra can make students less than optimal in improving their thinking skills. However, the use of learning videos can be used by students to remember continuously to be used as independent learning materials and the use of GeoGebra can be used to correct answers that have been obtained using manual methods.

Betrik Sihombing — 2025-01-31

This research is motivated by students' low mathematical problem solving abilities in mathematics learning process, which includes four indicators, namely understanding the problem, making a plan, implementation the plan and looking back. The aim of this research is to develop an e-module assisted by geogebra software to improve students' mathematical problem solving abilities. The method used is development research with ADDIE model, analysis, design, development, implementation and evaluation. Data collection techniques used are observation, interviews, questionnaires and tests. The research results show that e-module assisted by geogebra software developed on quadratic function material is suitable use for teaching material that can improve students' mathematical problem solving abilities. This is based on media and material expert validation results of 93% (very valid category), teacher practicality results of 88% and student practicality results of 94% (very practical category), student classical learning completion results of 97% (very effective category) which can achieving complete achievement of learning objectives, the results of student effectiveness questionnaire response to the e-module of 98% (very effective category). It can be concluded that e-module assisted by geogebra software developed on quadratic function material meets the criteria for validity, practicality and effectiveness, so it can be used to improve students' mathematical problem solving abilities.

Numeracy Skills Of Junior High School Students In Doing AKM (Minimum Competency Assessment) Type Problems

Iffah Fathimatuzzahro — 2025-01-31

In an effort to improve numeracy skills, the Ministry of Education and Culture has established the National Assessment as a form of education evaluation in Indonesia. The implementation of the National Assessment evaluation is measured through the Minimum Competency Assessment (AKM). The Pythagorean Theorem is one of the chapters that includes geometry and measurement materials, and algebra which requires the ability to analyze and solve problems. Understanding and practice questions using the AKM type of questions are needed so that students can easily interpret mathematical problems that arise in everyday life. The purpose of this study was to describe the numeracy skills of junior high school students in solving AKM type questions on the Pythagorean Theorem material. The subjects of this study were 12 students of Class VIII of SMP Brawijayasakta I Surabaya. This study used a qualitative descriptive method. Data collection techniques in this study were written tests and unstructured interviews. The data analysis technique used by the researcher was triangulation techniques which aimed to ensure the relationship between test results and interview answers. The results of this study indicate that Students in the high numeracy ability category are sufficient to fulfill indicator 1, and can fulfill indicators 2 and 3 well. For students in the low numeracy ability category, it is enough to meet indicator 1, to meet indicator 2 well and not to meet indicator 3. For students in the low numeracy ability category, it is enough to meet indicator 1 and not meet indicators 2 and 3.

Exploration of Ethnomathematics in Betawi Batik Motifs for Teaching Plane Geometry

Ririn Widiyasari — 2025-01-31

Batik is one of Indonesia's cultural heritages that must be preserved. Batik has different characteristics and philosophies in each region, one of which is Betawi batik. Betawi batik has various characteristics and philosophies in each motif which, if examined more deeply, are related to flat shapes or mathematical concepts. The relationship between culture and mathematics is also known as ethnomathematics. The purpose of this research is to explore the concept of flat shapes in Betawi batik motifs. The research method used is a qualitative method with an ethnographic approach. This research uses human instruments, namely the researchers themselves, where everything that happens in the field will be recorded by researchers using exploration and observation guidelines, digging and analyzing all documents found and presenting them in the research results. The result of this study is that in Betawi batik motifs there is a concept in the form of flat shapes. The flat shapes found in this type of Betawi batik motif are triangles, squares, rectangles, rhombuses, kites, trapezoids, and circles. The results of this study are related to the process of learning mathematics in schools and can be used as learning materials at the primary and secondary school levels.

Parents' Policy in Developing the Numerical Literacy of Their Teenage Children: A Descriptive Qualitative Study

Aulia Fonda — 2025-01-31

The Program for International Student Assessment (PISA) states that the literacy and numeracy of students in Indonesia are in the low category. Indonesia scored 366 and ranked 68 out of 81 countries. Previous research discussed parental involvement in developing early childhood literacy. This study aims to investigate parents' policies in developing numerical literacy in adolescent children. This study used a qualitative descriptive method. Data were collected through questionnaires filled in by parents and interviews related to the interaction between parents and children in the context of numerical literacy. There are 9 respondents, namely mothers of adolescent children who will be studied. The results showed that parents' policies in supporting numerical literacy include providing direct support in learning mathematics, providing adequate learning resources, and implementing daily activities related to numeracy. Obstacles to implementing this policy include parents' limited time, children's lack of interest in numerical literacy, and others. This study concludes that parents view the development of numerical literacy as “very important”. Parents' policies support the development of numerical literacy in adolescent children by involving children in financial management and playing an active role in their activities of adolescent children.
