Abstract

Elementary school teachers in Cluster II of the Gerung sub-district are very rare and some have never even used teaching aids in teaching mathematical concepts. That makes students have difficulty understanding abstract mathematics subject matter, while elementary school children are still in the stage of concrete or semi-abstract thinking. Therefore, this activity aims to empower elementary school teachers in Cluster II of the Gerung sub-district in implementing Kopermatik teaching aids (Math Game Box) by providing training to elementary school teachers on how to make and use Kopermatic props. Kopermatik is a set of elementary school mathematics teaching props that include teaching aids for learning algebra, geometry, and numbers. The training methods include (1) presentation of material, (2) demonstration, (3) making of teaching aids in groups, (4) presentation of group work results, and (5) evaluation and follow-up. The service activity was located at SDN 2 Dasan Geres, with 18 elementary school teachers as participants. all participants actively practice making props for number cards and fraction cards in groups of two. The results of this activity are : (1) all participants practice making props for number cards and fraction cards in groups of two, and (2) 95% of participants can demonstrate the props they made correctly. The results of the questionnaire showed that all participants were happy with this activity and hoped that it would be held again for a longer time and with more materials. Participants can understand the training material because it is interesting and easy to understand

Abstract

Elementary school teachers in Cluster II Gerung District are still very rare in using visual aids in teaching mathematical concepts. As a result, students have difficulty understanding abstract mathematical material, while elementary school children are still at the concrete thinking stage. Therefore, this activity aims to train and assist elementary school teachers in Cluster II Gerung District in implementing Kopermatik teaching aids (Mathematics Game Boxes) for classroom learning. The training method includes discussions and demonstrations in making and using Kopermatik teaching aids as well as simulations in utilizing the Kopermatik teaching aids. This service activity was carried out at an elementary school in Gerung District, with 18 elementary school teachers participating. The results of the data analysis show that the teachers participating in the activity: (1) are enthusiastic and communicative in participating in the activity, (2) can practice making Kopermatik mathematics teaching aids with quite good and varied results, (3) give positive response to the usefulness of Kopermatik teaching aids, and (4) more than 65% of teachers were able to answer each evaluation question correctly

Abstract

the engagement activity begins with the development of technology and communication, as well as the high demand for mathematics learning media by teachers. On the other hand, the quality of education, particularly in junior high schools, is still low. Teachers' competence, especially in media usage and development, is also low. Therefore, a workshop on media development will be conducted to enhance teachers' competence and the availability of learning media. The implementation methods for this engagement activity include material presentations, demonstrations, practical exercises, group discussions, and evaluation with feedback. The results of this engagement activity show that the majority of junior high school teachers in Central Lombok believe that the use of Geogebra and augmented reality in mathematics learning has the potential to improve students' understanding of concepts, interest, motivation, creativity, and learning outcomes. Teachers also acknowledge the importance of their role in effectively integrating this technology. Thus, the use of Geogebra and augmented reality-based learning media can provide positive benefits in enhancing the quality of mathematics education in schools. It is important to consider contextual factors and readiness when implementing Geogebra and augmented reality. The utilization of technology, especially Geogebra and augmented reality, should be tailored to the needs, availability of resources, and characteristics of each educational level.

Abstract

Number sense is important to be mastered by a prospective mathematics teacher as a basis for learning mathematics and makes it easier to train students' flexibility in solving math problems related to numbers. However, the results of preliminary studies show that there are indications that the prospective teacher's ability to operate numbers is not good enough. This study uses quantitative methods that aim to investigate the number sense component of mathematics teacher candidates who are still weak. The respondents involved in this study were 36 students who were prospective third-year mathematics teachers who had taken linear algebra courses. The instrument used is a 30-item number sense problem developed based on the number sense component, namely understanding and skills about numbers, understanding and skills using number operations, and applying number skills and operations in computing. This number sense test is done for 30 minutes. The results showed that the number sense ability of prospective mathematics teacher students was average with an average percentage of correct answers of only 51.57%. The third component in number sense is the weakest mastered with a percentage of correct answers of only 46.39%.
