In this study, 53 middle school teachers and 28 prospective secondary school teachers worked either individually or in pairs to pose mathematical problems associated with a reasonably complex task setting, before and during or after attempting to solve a problem within that task setting. Written responses were examined to determine the kinds of problems posed in this task setting, to make inferences about cognitive processes used to generate the problems, and to examine differences between problems posed prior to solving the problem and those posed during or after solving. Although some responses were ill-posed or poorly stated problems, subjects generated a large number of reasonable problems during both problem-posing phases, thereby suggesting that these teachers and prospective teachers had some personal capacity for mathematical problem posing. Subjects posed problems using both affirming and negating processes; that is, not only by generating goal statements while keeping problem constraints fixed but also by manipulating the task's implicit assumptions and initial conditions. A sizable portion of the posed problems were produced in clusters of related problems, thereby suggesting systematic problem generation. Subjects posed more problems before problem solving than during or after problem solving, and they tended to shift the focus of their posing between posing phases based at least in part on the intervening problem-solving experience. Moreover, the posed problems were not always ones that subjects could solve, nor were they always problems with “nice” mathematical solutions.

Perlunya kemampuan dalam membuat permasalahan/persoalan matematis sangat diperlukan oleh seorang guru. Hal tersebut berguna agar guru tidak hanya memberikan soal yang ada di buku saja. Guru dituntut kreatif; guru perlu memiliki kemampuan dalam membuat soal yang dibutuhkan oleh siswanya. Selama ini, kemampuan yang terus disoroti adalah kemampuan dalam menyelesaikan berbagai tipe soal dilihat dari daya pikir siswanya. Untuk kali ini, kita coba lihat dari sudut pandang perlunya kemampuan seorang guru untuk memiliki kemampuan pengajuan permasalahan matematis (mathematical problem posing) ini. Seiring dengan meningkatnya kemampuan membuat soal yang baik tentunya dapat meningkatkan kualitas pembelajaran di kelas. Kemampuan mathematical problem posing ini masih menjadi kendala bagi beberapa mahasiswa calon guru matematika, padahal kemampuan ini sangat diperlukan bagi mereka yang akan menjadi seorang guru yang baik. Oleh karena itu, pada kesempatan ini, kita akan coba paparkan problem posing sebagai suatu kemampuan matematis yang diperlukan oleh seseorang, terutama calon guru.The need for the skill to create mathematical problems/issues needed by a teacher. It is useful for teachers to provide problems that exist in books only. Teachers need to be creative; teachers need to have the skill to create questions that needed by their students. During this time, a skill that continues to be highlighted is the ability to resolve various types of problems seen from the intellect students. For this time, we look from the perspective of the need for the skill of a teacher to have the skill of mathematical problem posings. Along with the increased mathematical problem posing skill can certainly improve the quality of learning in the classroom. Mathematical problem posing skill is still an obstacle for some mathematics prospective teachers, but this skill is very necessary for those who would become a good teacher. Therefore, on this occasion, we will try to present problem posing as a mathematical skill needed by someone, especially prospective teachers.

The study tackled prospective teachers’ sense-making of mathematical problem posing and the impact of posing different contextual problems on their learning. Focus was on the generation of new problems and reformulation of given problems. Participants were 40 prospective elementary teachers. The findings provide insights into possible ways these teachers could make sense of problem posing of contextual mathematical problems and the learning afforded by posing diverse problems. Highlighted are five perspectives and nine categories of problem posing tasks to support development of proficiency in problem-posing knowledge for teaching.

Posing problems is an intellectual activity that is crucially important in mathematics research and scientific investigation. Indeed, some have argued that problem posing, as a part of scientific or mathematical inquiry, is usually at least as important as problem solving (Einstein and Infeld 1938; Hadamard 1945).
