Designing mathematical problems task through COVID-19 context

Abstract

This study aimed to produce PISA model mathematical problems for junior high school students using a valid and practical Covid-19 context. The research method used is design research with the type of development study. At the preliminary stage, a review of literature and design has been reviewed. Meanwhile, the formative evaluation phase only reaches the stage of self-evaluation, one to one, small group. Data collection techniques used were walkthrough, document review, and online interview. The problem developed in this study is related to the number of hand sanitizers that can be made based on available ingredients. The data analysis applied is descriptive. The result of the research is in the form of mathematical problems using a valid and practical PISA model COVID-19 context with 3 items in total. From the validation result in terms of content, constructs, and language based on the validator and one to one assessment, the PISA type mathematics problem with the context of Covid-19 has valid content, construction, and language. Practically, based on small group trials where all students can understand the purpose of the problem well, the students' thoughts easy to read and do not lead to diverse interpretations.
