Although, the history of mathematics presented that mathematics came from ancient Babylonia, but I disagree that ideas of mathematics have taken of it until contemporary periode. Based on Hans Freudental’s comment (Sutarto Hadi, 2005) mathematics as human activity, so i can assumpt that ideas of mathematics there was since first human being in world.
we intuitively research the realm of mathematical truth. In history of mathematatics, Thales found way of counting high of piramid not intentionally. We can can intuitively research in learning mathematics too. Experience of learning can make to research. For example, communications between teacher and student earn analysis, and made to research into.
Lesson Study represent an model construction of educator profession through study by kolaboratif and continuation have principal kolegalitas and mutual learning to develop build community learning. Lesson Study does not study, but in lesson studi activity teacher can choose and apply various method or study strategy which according to situation, condition and problem in learning. Teacher can do research in learning into through lesson study. Marsigit (2007) said that Lesson studies for secondary mathematics were carried out by mainly Classroom Action Research approach. They carried out to improve the teaching learning practices and to find more appropriate methods for facilitating students learning. Teachers’ experiences have been shared with other teachers and the lectures.
I agree with katagiri, attitude in learning mathematics not merely student sit better pay attention clarification of teacher. I assume Mathematical attitude according to katagiri is visible student activity, like Attempting to have questions, Attempting to maintain a problem consciousness, etc. But , how do teacher develop mathematical attitude in learning mathematics?
Problem solving can and should be taught! The process has been analyzed and can be represented as a series of steps, referred to as a heuristic plan, or, simply, heuristics. Teacher can develop problem solving process elicits mathematical thinking and method with develop reasoning and communication.

Bagus. Ibu telah menapak selangkah lebih maju. Sambil menyiapkan proposal sambil pula belajar, coba tolong ibu buat artikel tentang penelitian jenis R & D dan penerapannya untuk mengembangkan model-model pembelajaran. Selamat atas Blognya (Dosen: Dr. Marsigit)
Jika sudah mendapat referensi tentang R&D silahkan segera hubungi saya (Pembimbing: Dr. Marsigit)
