Abstract

Preservice mathematics teachers will eventually become mathematics teachers and teach mathematics in schools to students. Therefore, it is important to assess the numeracy skills of preservice mathematics teachers to develop their numeracy skills, which will positively impact students once they start teaching in schools. This study aims to describe the numeracy skills of preservice mathematics teachers about numeracy, including how well they can explore mathematical concepts in problems related to numeracy. This study is a qualitative descriptive. The subjects of this study are 28 mathematics education students from the University of Mataram. The instruments used in this study are questionnaires and tasks containing numeracy problems using the Sasak cultural context. Data analysis employs descriptive qualitative analysis, which includes data transcription, categorization, data presentation, description of the numeracy skills of teacher candidates, and conclusion. The results show that, in general, students have not been able to distinguish between numeracy and mathematics. Additionally, students still face difficulties in designing numeracy-oriented learning, especially using the socio-cultural context

Abstract

The understanding of partial-differential equation basic concept is the basic knowledge needed to understand and determine general solutions on partial-differential equations. From the observation on the partial-differential equation class, there are still some students who are unable to understand the basic concept of partial-differential equation. This study aims to discover how the development of interactive PowerPoint learning media is oriented to the basic concept understanding of partial-differential equation. This study was an R&D research using 4D model by Thiagarajan through some stages namely define, design, develop, and dissemination. The instruments used were media expert and material expert validation sheets, student and practitioner response questionnaires, and Quizizz-assisted tests. There were 14 slides on the results of interactive PowerPoint development which contained the title of materials delivered, the learning goals to be achieved, interactive activities, evaluation and references. The interactive PowerPoint learning media can be said to be valid by media expert judgments and material expert judgments, and is practical to use according to the results of student and practitioner response questionnaires. Interactive PowerPoint media is also effective in helping understand the basic concepts of PDP.

Abstract

The Pancasila Student Profile Strengthening Project (P5) is a form of implementation of the independent curriculum that aims to provide students with a more meaningful learning experience and process. P5 activities also apply the concept of differentiated learning, which emphasizes adapting to students' learning interests and readiness to obtain good learning results. Data in the field shows the lack of availability of the P5 module developed at SMPN 1 Pujut which is used as a guide for teachers and students in carrying out P5 activities. This research aims to create an E-Module based on the Strengthening Pancasila Student Profile (P5) Project as a Differentiated Learning Resource for Middle School Mathematics that is suitable for use. This type of research is Research and Development (R&D) using Plomp design research, including (1) preliminary research, (2) development or prototyping phase, and (3) assessment phase. The results of this research indicate that the P5 e-module is classified in the very valid category with content validity criteria of 90.28%, and construct validity of 90.97%. Therefore, the availability of interactive P5 modules helps teachers provide innovative ideas and references for creating similar or even better modules.

Abstract

This research aims to develop interactive learning media CAKU and Student Worksheets (LKPD) to improve students' understanding of set material in class VII. The research method used is Research and Development (R&D) with the ADDIE (Analysis, Design, Development, Implementation, Evaluation) development model. The analysis stage involves identifying needs and problems in learning set material. The design stage focuses on designing media and LKPD that suit the characteristics of class VII students. In the development stage, the media was prepared and tested on a small scale through peer teaching in the Innovative Mathematics Learning Study class which was attended by 16 students to obtain input and improvements. Implementation is carried out through field trials to measure the effectiveness of the media and LKPD that have been developed. Evaluation is carried out to assess the increase in students' understanding before and after using the learning media. The research results show that learning media is effective in increasing students' understanding of the concept of set. Apart from that, it is considered interesting and motivating for students to learn, thus making the learning process more interactive and fun. Thus, it is hoped that the development of the learning media CAKU and LKPD can become an innovative alternative tool for educators in teaching set material, as well as improving the quality of learning in class VII.
