Abstract

Professional teachers need to be skilled in planning their lesson. One of the activities to plan the lesson is analyzing the competence and teaching material demanded by the curriculum. This article aims to describe the Indonesian pre-service mathematics teachers’ skills in analyzing junior high school mathematics competence. The analysis is important to prepare the appropriate material for their students. This is qualitative research involving 26 pre-service teachers enrolled in the subject of Curriculum Analysis for Junior High School. First, they were assigned to analyze a given basic competence and were then challenged to select the appropriate materials and the indicators when the competence achieved according to Bloom taxonomy. Surprisingly, though there are many reference books available for sources of analysis, the teacher candidates found some difficulties in arranging the topics and composing the appropriate indicators. Some errors found such as the use of unmeasurable verbs, unclear activities, and illogical-irrelevant topics.

Abstract

The long-term objective of this research is to produce valid, practical, and effective textbooks for courses in international program of mathematics education of Universitas Ahmad Dahlan. For the short-term, this research aims to produce valid and practical textbook for number theory course. The validity was based on the relevancy towards the students’ expected competence, while the practicality was measured from the implementation of learning using the textbook. This research used design research with the type of development studies. It followed four steps, i.e. (1) preliminary research, (2) prototyping stage, (3) summative evaluation, and (4) systemic reflection and documentation. In the preliminary research, we analyzed the need of the textbook in the international program and found that the textbook of number theory course is very needed. In the prototyping stage, we wrote the textbook based on the need analysis. The prototype was then discussed with expert and revised in the stage of summative evaluation and applied to the lecture meetings. The result was the final product of the textbook used for the stage of systemic reflection and documentation when we wrote all the results according to the preset research framework. Finally, the developed number theory textbook is valid and practical.

Abstract

Javanese context is rich of phenomena potentially used as a starting point to learn mathematics. On the other hand, the Indonesian students’ performance in PISA is consistently low due to the small number of PISA-like problems which can be used to foster the students’ mathematical literacy measured in PISA. Therefore, this research aims to develop a set of PISA-like problems using the Javanese context targeted for 8th-grade students of Junior High School. It is a development study using Plomp’s framework in the stage of need analysis and prototyping. We have successfully developed a prototype of PISA-like mathematics problems using Javanese context. There are six items covering seven basic competences in the 8th-grade of junior high school. The items used various mathematics skills such as communication, representation, mathematization, devising strategies, and reasoning. We could explore some Javanese contexts such as traditional building, transportation, calendar system, community meeting, and historical place. Meanwhile the school mathematics materials include number sequence, Cartesian coordinate, relation, linear function, linear equation system in two variables, and Pythagorean theorem.

Abstract

Mathematical litreracy is defined as individual capacity to reason mathematically, to formulate, to employ, and to interpret mathematics, and to solve problems in the various real-life contexts. These skills are important for students but PISA – an OECD program to assess these skills – reported that the Indonesian students’ performance in mathematical literacy remains low for decades mostly due to instructional factor. It also happened in SMP N 2 Cimerak – a junior high school in Pangandaran, Indonesia, that the students still need a lot of improvement in mathematical literacy skills and their teachers also needs to develop capacity to teach the skills. This research aims to develop a valid and practical lesson plans which could be used to foster mathematical literacy. The lesson plans also include powerpoint presentation slides, students’ worksheet, teaching materials, and assessment instrument. It was a modified version of R&D introduced by Plomp which consist of stages: initial investigation, design, construction, evaluation, and final product. In the evaluation stage, we involved four experts to validate the lesson plans and 26 junior high school students to test the lesson plans, and revised them accordingly. The results suggest that the lesson plans are valid with the score of 4.46 (lesson plan), 3.96 (PPT slides), 4.38 (worksheet), 4.00 (teaching materials), dan 4.39 (assessment). The validity could be explained from the accommodation of mathematical literacy domains such as contexts (job and society, local environment maps), content (change and relationship, Cartesian coordinate), process (manifested in the problem-based learning), and the skills (communication, mathematization, representation, reasoning, devising strategies, using symbols, and using mathematics tools). The testing also resulted in 84.19 score of students’ positive responses and 3.92 (good) score of practicality. Moreover, the lessons also have potential effects in fostering students’ mathematical literacy viewed from the observation of mathematical literacy process, which suggest that 3.8% students in low performance, 53.8% students in intermediate performance, and 42.3% students in high performance. Therefore, the lesson plans were valid, practical, and having potential effect in fostering students’ mathematical literacy.

Abstract

Deaf children have auditory limitations and therefore rely more heavily on visual cues in their daily lives. For this reason, there is a need for media that can visualize mathematical concepts or materials. The aim of this study is to develop a learning modul for addition and subtraction topics and to assess the validity and practicality of the developed electronic module. We used the ADDIE R&D model which consists of five stages—analysis, design, development, implementation, and evaluation. We developed the e-module using Genially platform. The validity of the module was assessed by experts in mathematics education and inclusive education. Then, we tried out the module to seven fifth-grade deaf students at SLB Negeri 2 Bantul—a public school for students with special needs. The result of the validation by content experts got an average score of 4.2 (good), the validation by media expert got an average score of 4.16 (good), and the validation by teacher got an average score of 4.38 (very good). Moreover, the practicality testing got the average score of the students’ response at 4.2 (small group) and 4.33 (field testing), which means the module is practical.

Abstract

Students have unique and diverse characteristics. One of the strategies used to facilitate student diversity is through differentiation learning. The research aims to explain the findings or problems of case studies in learning Physics at SMAN 8 Yogyakarta and explain the differentiated learning to solve these problems. The research approach used is qualitative with the case study method. Data collection techniques use non-test techniques using documentation and observation. Based on the results, differentiated learning can facilitate the needs of students who have diverse learning modalities, including students with visual and kinesthetic learning modalities. The implementation of discovery learning using virtual laboratories assisted by PhET Colorado can be an alternative learning model in teaching Physics. Future research can measure students' knowledge, attitudes or skills in applying differentiated learning and combining it with other learning models

Abstract

The Indonesian performance in PISA mathematics consistently low in the last decade, despite the increasing awareness among mathematics educators regarding the importance of mathematical literacy. One of the core problems is the lack of mathematical literacy problems while the resources of contexts are available and rich. This research aims to develop a set of mathematical literacy problems using Jogja tourism context. It is an ADDIE research which includes the analysis, design, develop, implementation, and evaluation stage. We involved two mathematics educators as the experts to validate the problems and 441 junior high school students in Yogyakarta to try-out the problems. Finally, we successfully developed 35 valid items of mathematical literacy problems with Jogja tourism context in terms of content and construct. The availability of these word problems would be useful for mathematics educators to foster the students’ mathematical literacy at school.
