Kegagalan RZ Memecahkan Ill-Structured Problem Persegi Panjang

Siswa dituntut harus menjadi pemecah masalah yang handal dalam berbagai situasi, salah satunya ill-structured problems. Penelitian ini merupakan study kasus bertujuan untuk mendeskripsikan penyebab kegagalan RZ dalam memecahkan ill-structured problems tentang persegi panjang untuk menginvestigasi secara mendalam, proses, aktivitas subjek RZ. RZ diminta untuk memecahkan masalah kemudian dilakukan wawancara secara mendalam. Hasil penelitian menunjukkan bahwa subjek mampu merepresentasikan masalah dengan bahasanya sendiri. Subjek gagal membangun solusi yang sesuai dengan masalah dikarenakan penguasaan konsep segiempat yang parsial. Subjek menggunakan trial and error karena gagal mengaitkan masalah dengan konsep persegi yang merupakan kunci keberhasilan pemecahan masalah. Dalam memberikan justifikasi, subjek tidak mengalami kendala karena proses yang dilakukan adalah penghitungan saja tanpa memaknainya. Sedangkan, proses monitoring dan evaluasi yang dilakukan subjek mengalami kegagalan. Subjek kebingungan menentukan solusi akhir dikarenakan solusi yang dibangunnya tidak memenuhi syarat dari masalah. Untuk itu, guru mempunyai peranan untuk mengajarkan siswanya dalam membangun relasi antar konsep yang dapat dimanfaatkan dalam pemecahan masalah

Exploring high school teacher’s design of rich algebra tasks

The phenomenon in schools today is that teachers rarely change their tasks. However, the teacher's activities to change their tasks, build students' arguments, support solutions, and maintain arguments without long debates are important and exciting things to learn. This study explores the ideas of high school teachers about task design and practice in teaching mathematics. The authors surveyed twelve high school teachers who teach mathematics in East Java Province. First, the authors conducted preliminary observations to observe the design of mathematics teacher tasks for six months in eight schools. Second, the authors state that teachers are engaging and consistent in designing rich algebra tasks. Third, the authors examine the teacher's ideas through direct observation and unstructured interviews. The results show how teachers' ideas about task design enhance students' creative thinking by reforming tasks from textbooks into rich mathematics tasks. The design of the task carried out by the teacher is to create to stimulate creative thinking. The teachers also use their knowledge and understanding of the material and curriculum to modify mathematics tasks in students' mathematics books. The task given by the teacher is to improve students' reasoning, not just memorize formulas or properties
