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).
