Abstract
Abstract This research was driven by students’ difficulties in solving PISA-like mathematics problems on change and relationship content. The students were not familiar with solving contextual-based problems like PISA, and teachers tended to provide routine problems at low levels. For these reasons, this research aimed to produce a PISA-like mathematics problem that was declared valid, practical, and had potential effects on students’ mathematical proficiency. Design research used as the main framework of research with the type of development studies that had two phases: the preliminary and formative evaluation. Data were collected by conducting a walkthrough, test, interview, and document review. The developed PISAComat was valid from its compatibility with the PISA framework, which related to daily life problems in determining the length of the queue at the shopping center by using physical distancing context on change and relationship content. Practicality was seen from the developed PISAComat can be easily understood by students and well solved even with different strategies. Also, the developed PISAComat had potential effects based on students’ answers at the field test phase, such as understanding the problem, in reality, transforming the real-situation into a mathematical problem, solving a mathematical problem, and interpreting mathematical solution.
