Authors: Siswono T Y E , Kohar A W , Hartono S
Published: November 2019

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.

Most of teachers have used written test and oral test in the form of mid-semester and end-semester test well, but the process aspects such as skills and attitudes have not been implemented optimally. Therefore, it is necessary to do research to analyze the assessment process provided by teachers. This initial research was conducted in one of the high schools in Padang City, namely SMAN 15 Padang. Data analysis techniques used are tabulation and percentage. The data obtained from an assessment process conducted by teacher are around 80% results-based assessment and 20% process-based assessment, wherein the results-based assessment are more dominant than the process-based assessment. Skills indicators assessed in this study include: doing practicum (K1), conclude the results of the practicum (K2), make a presentation (K3), apply new knowledge (K4), and solve problems and questions (K5). While attitude indicators assessed in this study include: curious (A1), confidence (A2), responsibility (A3), discipline (A4), conscientious (A5), cooperation (A6). Suggestions raised based on the results of preliminary research that process-based assessment especially skills and attitudes need special attention by conducting further research to develop a process assessment instrument
