Teacher knowledge and beliefs are known to play crucial roles in shaping teacher teaching practice regarding mathematical problem-solving. Thus, assessing the teacher's quality of mathematical problem-solving can be traced through such three factors. This paper aimed at exploring the elements of mathematics-related beliefs, mathematics problem-solving knowledge for teaching, and problem-solving-based teaching practice needs to be improved by mathematics teachers. Some empirical findings of assessing those three factors from a two-year research project involving a total of 288 teachers from primary and secondary school on teacher's problem-solving were presented as the manifestation of teacher quality regarding mathematical problem-solving. More specifically, the teachers participating in such a research project were indicated to have beliefs about nature of mathematics, mathematics teaching and mathematics learning ranging from Instrumentalist view to problem-solving view. Also, it was found that teacher problem-solving content knowledge such as knowledge of mathematics problem and problem-solving strategies was insufficient to hold a problem-solving instruction. Furthermore, the teacher's teaching practice, assessed by observing how the teacher participants guide their students to solve a mathematics problem following Polya's four stages of problem-solving, range from directive to consultative teaching. In sum, beliefs, knowledge, and teaching practice are discussed as three interdependent factors which determine the quality of teacher's mathematical problem-solving. © 2019 IOP Publishing Ltd.
