The development of student worksheets based on higher order thinking skill for mathematics learning in junior high school

There are three purposes of this study. 1) to develop student worksheets based on Higher Order Thinking Skills (HOTS); 2) to test the feasibility of developed student worksheets, and 3) to analyse student assessments of developed worksheets. This research is a research and development (R&D). The development model is ADDIE which consists of 5 stages, namely Analysis, Design, Development, Implementation, and Evaluation. The study was conducted at SMP Negeri 1 Karanganyar in the academic year of 2018/2019. Data collection was obtained through observation, interviews, documentation, and questionnaires. Data analysis techniques used was critical analysis and comparative descriptive analysis. The results of the research were 1) This research and development had produced a worksheet based on HOTS on the subject of algebra; 2) Student worksheets developed were declared valid by experts and education practitioners, and 3) The results of the students' responses showed that the student worksheets that had been developed were interesting and the questions of HOTS presented were quite challenging to solve. Thus, students' worksheets based on developed HOTS were suitable to be used in mathematics learning.
