Developing Mathematics HOTS Test Items in Essay

Abstract

This research aimed to develop Mathematics HOTS test items in essay type in improving mathematical communication of tenth grade Science students in Senior High School. Research Development was applied as the research method. The Research Development used in this research was Thiagarajan, Semmel and Semmel model consisting of defining, designing, developing, and disseminating in developing qualified mathematics learning test instrument. In this research, the expert judgements by mathematics lecturer and teacher were conducted toward the developed instruments. There were field trials conducted for empirical validity. The field trials involved tenth grade Science students in 11 State Senior High School. Data analyzing technique used qualitative analysis to interpret the result of the expert judgments and quantitative analysis to test item validity and instrument reliability containing the developed test items. Furthermore, among seven HOTS test items for mathematical communication skill that were written, there were resulted three HOTS test items for mathematical communication skill which were valid, reliable, and practical.

Planning for Cultivation Numerical Literacy in Mathematics Learning for Minimum Competency Assessment (AKM) in Elementary Schools

“…Open Ended Problems (OEP) or learning with open problems means learning that presents problems with various solutions the way (flexibility), and the solution can also be diverse (multi-responsibility, fluency). Through highorder thinking, students will be able to distinguish ideas or ideas argue well, able to solve problems, able to construct explanations, be able to hypothesize and understand complex things to become more precise; where this ability clearly shows how participants learn to reason (Susetyawati & Nuryani, 2021). Not all students have good mathematical literacy skills.…”
