Abstract

This research was the qualitative research that aimed to improve students understanding of junior high mathematics study. In accordance with the object to be studied, then this research is done in 3 times open class consisting of the plan, do, and see for each cycle, with the subject of research was the students of mathematics education department of FKIP UNIPA whom contracting subjects junior mathematics studies. To improve students understanding of the material, implementation of peer tutor methods was continuously modified based on the findings of each cycle. Based on the results of the implementation of Lesson Study as much as 3 cycles obtained the concluded that the learning outcomes of learners used peer tutor approach that modified each cycle has a significant increase. This was evident from students who answered the test correctly given at the end of each meeting. In the first cycle, from 27 students only 4 who can answer the test correctly that is equal to 14.81%, the second cycle, from 27 learners only 10 which was able to answer the test correctly that was equal to 37,04%, whereas in cycle III, from 26 students 21 students able to answer correctly that was equal to 80,77%

Abstract

The purpose of this research was to develop an instrument that can be used to measure higher-order thinking skills (HOTS) in mathematics instructional of high school students. This research was conducted using a standard procedure of instrument development, from the development of conceptual definition, development of operational definitions, determination constructs, dimensions, and indicators, to the preparation of blue print, item preparation, expert validation, and testing. Data results from trials be analyzed using factor analysis and analysis of structural equation modeling (SEM). The data analysis shows that there are 9 factors HOTS that construct the instrument with good validity and reliability. This instrument classifies high school students in the five categories of HOTS ability. HOTS grouping results can be used by various interested institutions to evaluate the instructional of mathematics. These evaluations are used to determine the success of student learning and the success of teachers' teaching.
