Abstract

This study aims to describe students' mathematical communication skillsboth oral and written. The communication ability is observed through theapplication of cooperative learning model type TGT for set theory. Theresearch design was qualitative descriptive. The subjects of the study were 17students of class VII-B. The learning material were lesson plan,discussion group, game group, worksheet, game question, and written test.The research instruments were observation sheet of teacher activity, writtenand oral mathematical communication ability. The results of the study at thefirst meeting showed that the ability of oral mathematical communication hadsufficient category and written had low category. The second meeting of oralmathematical communication skills had sufficient category and written wasbetter than before. Oral mathematical communication improved at the thirdmeeting, while written in the low category. The fourth meeting was increasedin the ability of oral and written mathematical communication, for high oralmathematical communication and written with high category as well. Thestudents' mathematical communication skills from the first to fourthmeetings had increased. The average overall ability of oral and writtenmathematical communication was sufficient

Abstract

This study aimed to describe learning plan on Opportunity material usingTeams Games Tournaments (TGT) with a scientific approach, and to knowstudent learning activities on learning materials opportunities using TeamsGames Tournaments (TGT) with scientific approach, as well as to know theresults of student learning on learning materials Opportunities using TeamsGames Tournaments (TGT) with scientific approach. Type of this research isdescriptive and the approach used is qualitative and quantitative. Techniqueof collecting data were observation, test, and documentation. The resultsshowed that the planning of TGT learning was only based on 4 components:(1) class presentations, (2) teams, (3) games, and (4) tournaments as well asthe non-implementation of group awards and components combined withscientific approaches, while student learning activities are in type of “good”category since the test results showed that 28 students were complete and 6students were unfinished. In classical, students' completeness reached 82.3%and was said to be complete. These results indicated that learning activitieswith TGT model with scientific approach is good to be applied.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan peningkatan koneksi matematis siswa melalui pembelajaran berbasis masalah. Metode penelitian ini menggunakan pendekatan deskriptif dengan data kualitatif. Hal ini ditinjau dari keterlaksanaan pembelajaran berbasis masalah dan indicator peningkatan koneksi matematis. Penelitian dilalukan selama empat kali pertemuan dengan subyek penelitian kelas IPA dan kelas IPS. Data diperoleh dengan cara mencatat pada lembar catatan lapangan dan lembar observasi dengan bantuan observer. Hasil dari penelitian ini yaitu adanya peningkatan kemampuan koneksi matematis siswa dalam mempelajari materi eksponen dan matriks. Hal ini ditinjau dari analisis hasil pengerjaan soal siswa yang sudah dapat mengkaitkan materi sebelumnya. Akan tetapi, pada indicator koneksi matematis dalam kehidupan sehari-hari, siswa belum dapat menjelaskan adanya keterkaitan materi dalam kehidupan sehari-hari.

Abstract

The purpose of this study is to describe students’ error on (1) the ability to understand the term of algebraic forms, and (2) the ability to communicate the term of algebraic forms into words and verbal forms. This is a case study. The study shows that: (1) the ability to understand the term of algebraic forms are low because of misunderstanding the slight differences between exponent and algebra itself, and (2) the ability to communicate the term of algebraic forms into words and verbal forms are challenging for them especially when they do not really understand the concepts.

Abstract

Mahasiswa sebagai calon guru harus memiliki kemampuan dalam melakukan pembuktian matematis. Kemampuan tersebut berfungsi untuk meyakinkan seseorang akan suatu rumus ataupun teorema. Semakin tinggi kemampuan mahasiswa dalam melakukan pembuktian akan berdampak pada peningkatan keterampilan pembuktian matematika siswa. Secara umum metode pembuktian yang dikenal oleh siswa adalah pembuktian secara langsung dan tidak langsung. Tujuan dari penelitian ini adalah untuk mengetahui kemampuan mahasiswa dalam melakukan pembuktian ditinjau dari proses sistematisasi. Penelitian ini juga bertujuan untuk mengetahui faktor apa saja yang mempengaruhi kemampuan siswa dalam melakukan pembuktian matematis. Penelitian ini dilakukan dengan menggunakan pendekatan kualitatif. Hasil penelitian yang dijelaskan secara deskriptif menunjukkan bahwa kemampuan pembuktian mahasiswa ditinjau dari proses sistematisasi masih lemah, mahasiswa belum memahami perbedaan antara rumus, definisi, teorema ataupun sifat. Selain itu, mahasiswa juga belum mengaitkan definisi, sifat, ataupun teorema yang relevan dengan pembuktian yang dilakukan. Akibatnya mahasiswa menyelesaikan soal dengan cara coba-coba. Salah satu faktor yang mempengaruhi hal tersebut yaitu kurangnya latihan dalam mengerjakan soal yang berbasis pembuktian matematika.

Abstract

Probolinggo Regency has a low literacy rate (78.09%) which is below the average of the East Java Province (88.34%). This data is supported by the recapitulation results of the Directorate of Literacy and Equality Education in 2014 which states that the illiteracy rate in Probolinggo Regency is 64.163 people. Meanwhile, this regency is considered having a high potential in the field of fisheries through catfish farming, located in Sumberasih District. This article discusses the results of the dissemination of illiteracy eradication using instructional book of catfish cultivation. The empowerment method implemented was Empowerment and Development. The instruments used were interview, observation, document, questionnaire, and test. On trial phase, a mentoring was done to the learning community that was called WB. Prior to the mentoring session, pretest was implemented then posttest afterwards which were all done to the WB. Results show that there was an improvement on class average grade, previously it was 58,5 subsequently after the use of illiteracy eradication book, the average grade has improved to 79. The responses gathered from the WB towards the instructional book were very positive. Thus, instructional book of catfish cultivation can be used as a textbook in illiteracy tutorial in minapolitan area.

Abstract

This study examined the learning of Pi (π) numbers in elementary school mathematics. This research was conducted by employing case study method containing a single case concerning the Pi (π) numbers. A total of 432 pre-service teachers participated in the study from the academic year of 2019-2020. This research employed observation, interview, and document analysis as the data collection tool. The conduct of the research involving the teachers and pre-service teachers was made in the classroom environment. The practice that participants posed for the account of Pi (π) number were analyzed by descriptive analysis technique in the scope of qualitative analysis. The data obtained from the participants were summarized and interpreted according to the predefined theme, and findings were arranged by a direct citation of the problems. Based on the analysis of the research, it showed that participants had problems in determining Pi (π) numbers as Pi (π) numbers are only taught by memorization methods. The teachers also did not understand about the source of Pi (π) number. Learning Pi (π) numbers are directly practiced through problems and formulas. Understanding the formula of plane figures is also not yet understood, so teachers and students basically only memorize the formula.
