Abstract

Heuristic strategy is one of the mathematics problem solving strategies to gain effective results. This research aimed to analyze the use of the heuristic strategies based on the modification of the Krulik and Rudnik model. This research discovered and classified the students’ heuristic strategies which can be used as a basis to provide assistance in the learning. This research was a qualitative research involving 32 students of SMP Muhammadiyah 4 Yogyakarta as its subjects. The research variables are the indicators of the Krulik and Rudnik heuristic models which the students performed including: read and think, explore and plan, select a strategy, find and answer, as well as reflect and extend. The data was taken through questionnaire and interview methods. The result suggested that: 2 students (6.25%) were in the good category as they did all of the heuristic strategies more often; 21 students (65.62%) were in the fair category since they implemented some indicators of the heuristic strategies; and 9 students (28.13%) were in the poor category since they were lack in implementing the heuristic strategies. In all categories, indicator of find and answer was more oftenly done by the students while the indicator of explore and plan was less done.

Abstract

This article aims to investigate how mathematics education students in Universitas Ahmad Dahlan solve PISA mathematics problems. This research used the descriptive method with the qualitative approach and supported with quantitative data. Research subjects were 20 new students of mathematics education at Universitas Ahmad Dahlan in the 2016/2017 academic year. We translated the 2012 PISA instrument and used it to collect data on students’ mathematical literacy skills and to identify their difficulties. All the data were analyzed based on PISA’s framework. The result shows that, in general, 65.7% of students were able to understand the problems and plan their strategies to solve them. Meanwhile, only 46.9% among them could answer correctly. In addition, only 36.8% of the students were able to understand the level 6 problems while only 23.7% among them answered correctly. The students performed well in the interpretation process towards the problems with individual and social contexts. However, they found difficulties in the formulation and employment process of the problems, especially in the work and scientific context.

Abstract

Learning mathematics has a significant contribution to the students’ daily activities, one of which is on social arithmetic topic. The implementation of social arithmetic, in general, is mostly found in buying-selling and banking activities. However, students still find difficulties in understanding this topic. It is because the teaching and learning activities still use a conventional approach, which restricts the students to imagine how it is implemented in daily life. Therefore, this paper aims to describe the innovative learning activities of social arithmetic among junior high school students using the Realistic Mathematics Education (RME) approach. This research was conducted in three meetings, and the researcher acted as the teacher in the class. The results showed that the innovative learning of social arithmetic using the RME approach and word problems could improve the students’ learning outcomes with an average score of 81.92% and 92.59% of the total of students scored above passing grade.

Abstract

Salah satu kegiatan penting dalam merencanakan pembelajaran adalah menyusun silabus dan rencana pelaksanaan pembelajaran (RPP). Penerapan Kurikulum 2013 membuat guru harus menyesuaikan diri dalam menyusun silabus dan RPP berpendekatan saintifik. Guru-guru matematika SMA/SMK Muhammadiyah di Kabupaten Gunungkidul merupakan target sasaran kegiatan pengabdian kepada masyarakat yang tepat mengingat mereka belum pernah mendapatkan bimbingan teknis yang memadai. Tujuan kegiatan pengabdian ini adalah untuk melatih dan memotivasi guru agar mampu menyusun silabus dan RPP yang ideal. Kegiatan pengabdian dilaksanakan dalam dua tahapan, yaitu workshop dan pendampinga. Hasil kegiatan pengabdian menunjukkan bahwa para guru telah berusaha mencoba menerapkan silabus dan RPP hasil workshopdan kegiatan mandiri dengan baik. Adapun umpan balik yang diperoleh menunjukkan bahwa pada tema workshop sesuai dengan kebutuhan peningkatan profesionalisme guru dan optimis tujuan workshop dapat tercapai. Daya dukung workshop berupa fasilitas ruang maupun fasilitas pendukungcukup memadai sehingga workshop bisa berjalan dengan lancar, baik, tepat waktu, dan menyenangkan. Peserta sangat mendukung adanya pelatihan lanjutan.

Abstract

Pembelajaran matematika berbahasa Inggris merupakan salah satu skill tambahan menjadi guru yang unggul terutama di era globalisasi. Banyak sekolah juga memiliki program kelas unggulan dengan salah satu kriteria unggulannya adalah kelas berbahasa Inggris, salah satunya adalah SMP Muhammadiyah 1 Yogyakarta. Untuk masuk kelas ini, siswa baru harus melewati seleksi Bahasa Inggris. Hal yang sama ditunjukkan oleh SMP Muhammadiyah 2 dan SMP Muhammadiyah 3 Yogyakarta. Sekolah-sekolah tersebut juga memberikan perhatian pada kemampuan berbahasa asing para siswanya. Tujuan kegiatan pengabdian ini adalah untuk melatih dan memotivasi guru agar mampu menyusun RPP dan menyiapkan materi matematika berbahasa Inggris. Kegiatan pengabdian dilaksanakan dalam dua tahapan, yaitu workshop dan pendampinga. Hasil kegiatan pengabdian menunjukkan bahwa para guru telah mampu menyusun RPP berbahasa Inggris hasil workshop dan kegiatan mandiri dengan baik. Adapun umpan balik yang diperoleh menunjukkan bahwa guru optimis tujuan workshop dapat tercapai. Daya dukung workshop berupa fasilitas ruang maupun fasilitas pendukung cukup memadai sehingga workshop bisa berjalan dengan lancar, baik, tepat waktu, dan menyenangkan. Persepsi peserta terhadap kebermanfaatan program juga baik.

Abstract

Masyarakat Dusun Plurugan dan Dusun Dongkelan Bantul memiliki sumber daya manusia yang baik, namun belum optimal. Kaum muda belum bersinergi dengan baik sehingga belum mampu diberdayakan untuk menjaga kondusifitas jam belajar di lingkungan kampong, salah satunya dalam belajar dan mengaji. Hal ini ditunjukkan pula dengan kurang berkembangnya prestasi anak-anak baik dalam bidang keagamaan maupun akademik. Oleh karena itu, KKN Alternatif 61 Universitas Ahmad Dahlan berusaha membantu agar taman pendidikan Al Qur’an dapat dilakukan secara merata kedua dusun tersebut dan mencanangkan program jam belajar masyarakat. Dampak dari kegiatan KKN ini adalah: (1) terciptanya kesadaran masyarakat akan pentingnya belajar ilmu agama maupun ilmu umum; (2) peningkatan pengetahuan anak-anak dalam belajar membaca Al-Qur’an, dan (3) meningkatnya antusiasme anak-anak dalam kegiatan taman pendidikan Al Qur’an.

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.
