Abstract

Lesson Study for Learning Community (LSLC) merupakan salah satu usaha pembinaan pada profesi pendidik, yang menekankan pentingnya pengkajian pembelajaran secara kolaboratif dan berkesinambungan berlandaskan prinsip-prinsip kolegalitas dan mutual learning untuk membangun komunitas belajar. Tujuan yang ingin dicapai melalui kegiatan Implementasi LSLC ini adalah meningkatkan pemahaman dan keterampilan guru Matematika SMP yang tergabung dalam MGMP pokja Cakranegara-Sandubaya Mataram berkaitan dengan: i) pengertian dan fungsi, serta praktik LSLC; ii) dalam merancang (plan), melaksanakan (do), refleksi (see), dan re-design pembelajaran; iii) membangun kolegialitas antar guru-guru matematika SMP dalam membelajarkan peserta didik melalui tukar pengalaman melalui Implementasi LSLC. Kegiatan ini menggunakan beberapa metode, yaitu: Ceramah, Tanya jawab, Simulasi, Diskusi, serta melakukan pendampingan saat guru-guru matematika melaksanakan tahapan LSLC secara luring dan daring dalam 2 siklus. Hasil dari kegiatan pengabdian dapat menambah pemahaman dan keterampilan peserta pada: i) pengertian dan fungsi, serta praktik LSLC; ii) membuat dan menggunakan aplikasi komunikasi digital dalam kegiatan pembelajaran daring dan memanfaatkan aplikasi komunikasi digital tersebut dalam Implementasi LSLC; iii) kegiatan plan, do, see, dan re-design pembelajaran seperti yang diatur di kurikulum tahun 2013 dan instruksi menteri Pendidikan dan Kebudayaan; iv) peningkatan kolegialitas antar guru-guru matematika SMP yang tergabung dalam pokja Cakranegara-Sandubaya Mataram dalam membelajarkan peserta didik melalui tukar pengalaman.

Abstract

The learning of addition and subtraction that usually be done in sequence impact students’ tendency to separate type of the strategies employ to solve the related problems. In fact, there are a number of situations that can be observed and solved through both lenses. Therefore, in this study we designed a simultaneous addition and subtraction of two-digit numbers learning trajectory. The learning activities were constructed based on Realistic Mathematics Education (RME) Approach. This design study was conducted in three steps consist of preliminary study, teaching experiments, and retrospective analysis. The teaching experiments were done in two cycle, the first was done with four students and the second was done with 33 students in two classes of an elementary school located in Singaraja, Bali. The data related to number sense ability were gathered from observation and students’ written work in solving worksheet and post-test. The collected data were analyzed using constant comparative method. From the results, we found that a simultaneous learning of two-digit numbers addition and subtraction were effectively develop the students’ number sense and encourage the students to develop efficient counting strategies.

Abstract

Matematika adalah ilmu yang mengamati cara kerja pikiran, dan cara terbaik untuk melatih kemampuan, serta mengembangkan kekuatan dan ketepatan berpikir. Berpikir dapat difokuskan melalui aktivitas pemecahan masalah. Memecahkan masalah bukan hanya untuk menerapkan matematika, melainkan untuk belajar matematika yang baru. Aktivitas memecahkan masalah banyak ditemukan pada pemecahan soal-soal kompetisi sains nasional (KSN) atau kompetisi sejenis. Memecahkan soal-soal KSN tidaklah sama dengan mengerjakan soal latihan pada umumnya. Tidak sedikit ditemukan siswa/peserta mengalami kesulitan memecahkannya. Bahkan guru cukup kesulitan membelajarkan pemecahan masalah materi yang akan dilombakan. Hal ini mengindikasikan pentingnya sebuah desain pembinaan untuk mempersiapkan para siswa dalam menghadapi KSN. Desain yang ditawarkan adalah desain blok semi kontinu, yakni sebuah desain pembinaan yang diberikan sebanyak 2-3 kali pertemuan setiap minggunya dan berjalan selama 8 minggu atau lebih, dengan program pembinaan terdiri dari 30% pemantapan materi, 50% problem solving, dan sisanya 20% moderasi. Desain ini disosialisasikan berdasarkan flow-map, yang terdiri dari 9 tahapan.

Abstract

The present study is a part of design research in local instructional theory in a pre-algebraic lesson using the Realistic Mathematics Education (RME) approach. The article will focus on recommendations for the type of pre-algebra class that supports elementary school students’ algebraic thinking. As design research study, it followed the three steps of preliminary studies, teaching experiment and retrospective analysis. The subject of the study is 32 fifth grade students of MIN 2 Palembang during the teaching experiment phase. The data were gathered from students’ worksheets, lesson observation and interviews with the students. Data analysis was done using a constant comparative qualitative method. The results from the study indicate that pattern investigation in pre-algebra class that visualized geometrically supports the students to identify the form of the pattern and construct generalization.

Abstract

English for Mathematics (EFM) is one of the important courses to prepare the prospective mathematics teacher in teaching mathematics using English as language of instruction. Besides that, EFM also enable the students in mathematics education department to employ more references as learning sources. Reflected to the important of students’ ability in EFM, we plan to develop the textbook related to the course. The whole study will use the method of Research & Development with three steps of Preliminary Research, Prototyping Stage dan Assessment Phase. The present study was focused on the first stage to analysis the needs of the textbook development. The subjects were 27 students of second year mathematics education study program in a state university in Nusa Tenggara Barat, Indonesia. The subjects were experienced the course of EFM in previous year. The data were gathered from students’ written work and interview with students and lecturers of EFM. We analyzed the data using quantitative descriptive method to evaluate the students’ mastery in EFM. From the analysis, it was found that the students’ score were lacking in mathematical terms and spoken language of mathematical symbols. The interview with the lecturers also confirmed that the learning sources in EFM is still limited. Therefore, to support the students in learning EFM better, the textbook is highly needed.

Abstract

Blended learning is a learning that combines face-to-face and online learning. Several studies have shown that blended learning has a positive effect on collaborative skills. The aim of this study is to determine the collaborative skills of pre-service mathematics teachers after using blended learning. The focus of this study is 4 indicators of collaborative work skills, namely quality of work, problem solving skills, working with others, and focus on the task. This type of study is a case study. The participants were 23 pre-service mathematics teachers in second year. Data collection was carried out using a collaborative questionnaire. Data were analysed using quantitative descriptive methods. The results showed that the criterion for quality work of students was 47.83% average. The criterion for problem solving skills was 47.83% very high. The criterion of working with others was 86.96% very high. The criterion for focus on the task was 82.61% very high. Therefore, blended learning possesses positive effects towards pre-service mathematics teachers.

Abstract

The aim of this study is to describe errors output when pre-service mathematics teachers were writing output of the syntax that given in macro excel manually. This research is a qualitative descriptive research with 101 participants from 2nd year pre-service mathematics teachers from one of state university at Nusa Tenggara Barat, Indonesia. Instrument used consists of one syntax that has 8 outputs when it is run and that will be analysed using Newman’s procedures. The eight outputs come from 3 types of output, namely text, numbers, and count. The result showed that the average percentage of syntax output writing errors was 87.13%. It also indicated to reading errors of 48.51%, comprehension errors of 18.81%, transformation errors of 83.17%, process skill errors of 20.79%, and encoding errors of 87.13%. Based on the result, errors occur when participants incorrectly write output and wrong in writing the result of the count. In addition, factors that caused these errors are 1) participants were not trained in providing information that was in the problem, 2) participants did not read the instructions in the problem correctly, and 3) participants did not pay attention to the suitability of syntax and output as was learned before. This research can be a reference for lecturers to develop learning about programming languages that can make students understand the use of syntax with the emphasis on manual syntax learning which will make their logic easier when applyng the syntax on a computer.
