Abstract

Penelitian ini bertujuan mendeskripsikan proses pengembangan RPP dan LKS bangun ruang sisi datar dengan pendekatan kontruktivisme berbasis kemampuan penalaran matematis. Serta mendeskripsikan kevalidan dan kepraktisan RPP dan LKS yang telah dikembangkan tersebut. Model pengembangan yang digunakan dalam penelitian ini adalah model ADDIE yang terdiri dari lima tahap yaitu analisis, desain, pengembangan, implementasi, dan evaluasi, namun dibatasi sampai tahap pengembangan. Adapun validator dalam penelitian pengembangan ini adalah dua orang dosen dan satu orang guru matematika. Instrumen penelitian terdiri dari lembar validasi RPP dan LKS untuk mengukur kevalidan dan kepraktisan RPP dan LKS yang dikembangkan. Hasil penelitian menunjukkan kevalidan RPP dari pertemuan 1 hingga 4 rata-rata total validitas masing-masing sebesar 4,19; 4,19; 4,2 dan 4,2, dengan klasifikasi sangat valid. Artinya, RPP bangun ruang sisi datar dengan pendekatan kontruktivisme berbasis kemampuan penalaran matematis dari pertemuan 1 hingga 4 telah sesuai dengan perangkat pembelajaran berdasarkan Permendikbud no 22 tahun 2016. Sedangkan kevalidan LKS bangun ruang sisi datar dengan pendekatan kontruktivisme berbasis kemampuan penalaran matematis dari pertemuan 1 hingga 4 telah sesuai dengan komponen menurut Depdiknas. Berdasarkan pernyataan yang diberikan oleh tiga validator bahwa pada setiap pertemuan RPP dan LKS yang dikembangkan “dapat digunakan dengan sedikit revisi dan tanpa revisi” . Artinya telah memenuhi kriteria “praktis” jika digunakan di lapangan atau dalam pembelajaran.

AbstrakSalah satu wujud pengembangan keprofesianalan guru adalah menulis artikel ilmiah dan publikasi artikel ilmiah. Oleh karena itu, hendaknya guru terus belajar menulis artikel ilmiah untuk diseminarkan maupun dipublikasikan di jurnal. Kenyataan di lapangan menunjukkan bahwa sebagian besar guru belum mampu menghasilkan dan melakukan publikasi ilmiah. Tujuan kegiatan pengaabdian ini adalah meningkatkan motivasi dan kemampuan guru dalam menulis artikel ilmiah dari hasil penelitian yang dapat digunakan sebagai salah satu persyaratan pengajuan kenaikan pangkat sehingga berdampak juga terhadap profesionalitas guru. Kegiatan pengabdian yang dilaksanakan menggunakan metode ceramah, tanya jawab dan simulasi. Kegiatan pelatihan penulissan artikel ilimah yang telah dilaksanakan dapat meningkatkan motivasi guru untuk menulis artikel ilmiah; guru memiliki pengetahuan dan kemampuan memilih tempat publikasi yang sesuai; guru memiliki pengetahuan tentang cara mencari sumber refrensi mutakhir melalui google scholar; guru memiliki pengetahuan tentang trik untuk publikasi artikel ilmiah hasil penelitian; guru dapat mengetahui bagaimana membuat draft artikel ilmiah hasil penelitian sesuai dengan tamplate jurnal yang dituju; seluruh peserta pelatihan memiliki pandangan positif terhadap pelatihan penulisan artikel ilmiah dan memandang tingkat kebermanfaatan pelatihan pada tingkat bermanfaat dan sangat bermanfaat.AbstractOne form of teacher professional development is writing scientific articles and publishing scientific articles. Therefore, teachers should continue to learn to write scientific articles to be disseminated or published in journals. The reality on the ground shows that most teachers have not been able to produce and do scientific publications. The purpose of this service activity is toincrease the motivation and ability of teachers to write scientific articles from the results of research that can be used as one of the requirements for submission of promotions so that it also impacts on teacher professionalism. Community service activities carried out using lecture, question and answer and simulation methods.

Abstract

Tujuan penelitian ini adalah mendeskripsikan kemampuan pemecahan masalah mahasiswa calon guru sekolah menengah berdasarkan tahapan Polya pada penerapan konsep bangun layang-layang. Penelitian ini merupakan penelitian kualitatif deskriptif, yang dilakukan pada 10 mahasiswa calon guru matematika semester 8, di salah satu perguruan tinggi swasta di Provinsi Jawa Barat, Indonesia. Pengumpulan data dilakukan melalui tes, observasi, dan wawancara. Analisis data dilakukan melalui triangulasi data berdasarkan hasil tes, observasi dan wawancara. Analisis nilai mata kuliah geometri terdapat lima kategori tinggi (KT), tiga kategori sedang (KS) dan dua kategori rendah (KR). Triangulasi data menunjukkan bahwa seluruh mahasiswa calon guru KT, KS, dan KR tidak memeriksa kembali sousi yang diperoleh dalam menyelesaikan soal pemecahan masalah. Mahasiswa KT melakukan tahap penyelesaian maslah sampai pada tahap 3, terdapat dua mahasiswa yang memperoleh solusi yang benar, satu mahasiswa memperoleh solusi yang salah disebabkan kesalahan operasi hitung, dua mahasiswa tidak mempeleh solusi disebabkan kurang teliti dalam membaca soal dan kesulitan operasi hitung. Mahasiswa KS, tahap penyelesaian maslah sampai pada tahap 3, terdapat  satu mahasiswa yang memperoleh solusi yang benar, dua mahasiswa memperoleh solusi yang salah disebabkan kesalahan operasi hitung. Mahasiswa KR, satu mahasiswa menyelesaikan masalah sampai pada tahap 3, memperoleh solusi namun solusinya salah disebabkan kesalahan operasi hitung, satu mahasiswa tidak memahami soal yang diberikan dan lupa konsep yang harus digunakan dalam menyelesaikan masalah.

Abstract

Pemecahan masalah non-rutin merupakan salah satu aspek dari pengetahuan konten matematika yang harus dimiliki oleh calon guru matematika (MCGM). Tujuan penelitian ini bertujuan untuk menganalisis kemampuan pemecahan masalah non-rutin dari MCGM  pada topik segiempat berdasarkan kategori nilai mata kuliah geometri. Metode penelitian menggunakan kualitatif deskriptif dengan pendekatan studi kasus dilakukan pada 10 MCGM  yang merupakan mahasiswa semester 8 yang akan melaksanakan tugas akhir penelitian (skripsi) topik segiempat, pada salah satu universitas swasta di Jawa Barat. Instrumen yang digunakan adalah tes pemecahan masalah non-rutin, observasi dan wawancara. Teknik analisis data dilakukan dengan triangulasi data. Faktor lupa rumus dan konsep tentang topik segiempat, kesalahan algoritma dan rendahnya penalaran menjadi penyebab dalam ketidakmampuan MCGM dalam pemecahan masalah non-rutin. Kesimpulan penelitian ini adalah kemampuan pemecahan masalah non rutin dari MCGM kurang. Berdasarkan tahapan pemecahan masalah Polya, MCGM dengan kategori nilai mata kuliah geometri tinggi kesulitan pada tahapan ke-3 (menjalankan rencana). MCGM dengan kategori nilai mata kuliah geometri sedang dan rendah  kesulitan pada tahapan ke-2 (menyusun rencana) dan ke-3 (menjalankan rencana).Non-routine problem solving is one aspect of mathematics content knowledge, and must be possessed by pre-service mathematics teachers (PSMTs). The purpose of this study was to analyze the non-routine problem-solving abilities of PSMTs on quadrilateral topic based on score of plane geometry course category .Research methods used qualitative descriptive with a case study approach conducted at 10 PSMTs who were students in the 8th semester, who would conduct research final project (thesis) on quadrilateral topics, at one of the private universities in West Java. The instruments used were non-routine problem solving tests, observation and interviews. The data analysis technique was done by data triangulation. The forgetting factor of formulas and concepts about quadrilateral topics, algorithmic errors and low reasoning are the causes of PMSTs inability to solve non-routine problems. Conclusion of this research is the non-routine problem solving ability of PMSTs was lacking. Based on the stages of mathematical problem solving Polya’s, PMSTs with high score of plane geometry course difficulties on stage 3 (carrying out the plan). PMSTs with category medium and low score of plane geometry courses have difficulty on stages 2 (devising a plan) and 3 (carrying out the plan).
