Abstract

• This study investigated middle school students’ mathematical proficiency in the mathematics classroom featured in conceptual understanding, procedural fluency, strategic competence, adaptive reasoning and productive disposition among six hundred Grade (8) students in Yangon Region. A descriptive research design was adopted and two types of instruments: a mathematical proficiency test reflected in former four strands and a productive disposition questionnaire towards mathematics were employed. The internal consistency reliability coefficient for the test was (.714) and that for questionnaire was (.704). The collected data were analyzed using descriptive statistics of frequency, percentage, mean, and standard deviation and inferential statistics of Pearson product-moment correlation. Research findings revealed that most of the students had moderate level of mathematical proficiency. Moreover, the results showed that students’ procedural fluency was the highest and strategic competence was the lowest among the former four strands. There was a significant positive relationship among five strands of mathematical proficiency. Grounded on this baseline study, it was thus, suggested that first, a nationwide survey on mathematical proficiency at all grades should be conducted and then, intervention program should be mapped out to cater students’ current level.
