Abstract

The test instrument given by the teacher to students has not required students to think at a high level in mathematics, the important thing is that students must be familiar with questions that require High Order Thinking Skill (HOTS) to compete with other countries which can be seen in the TIMSS and PISA scores. The purpose of this study was to determine the students' high-order mathematical thinking skills, as well as to determine the validity, reliability, difficulty level, and differentiating power of the High Order Thinking Skill (HOTS) oriented test instrument. This developmental research uses the ADDIE type.. There were 57 students who were used as subjects in this study. The results showed that 15 questions that were considered successful and valid were developed, this is the average score of the test instrument assessment by experts of 91% and the validity of each test item is declared "valid" because tcount ≥ ttable. The reliability of the test instrument for each package of questions was rated as reliable in the high category. In the analysis of the level of difficulty, it appears that the results are in the easy and medium categories. In the analysis of discriminatory power, it appears that the results are quite good and good. The average results of students' high-order mathematical thinking skills are insufficient category.

Abstract

This study aims to analyze the errors of students with HOTS abilities at high, medium and low levels and identify student errors in solving HOTS (Higher Order Thinking Skill) type questions in terms of gender. This type of research is qualitative with a case study approach. The research subjects were selected 3 male students and 3 female students, each of which the HOTS ability level was high, medium and low consisting of 2 students. Data collection techniques used HOTS-type tests and interviews. The analytical framework was developed based on Newman's theory of error categories. The data obtained were tested for validity through credibility, transferability, dependability, and confirmability tests. The results showed several differences in the types and percentages of errors made by male and female subjects in solving HOTS-type questions. The biggest mistakes made by both genders in the material of number patterns, sequences, and series are misunderstandings of 33.33%, followed by errors in determining the final answer of 23.02%, transformation errors of 22.22%, errors in the completion process of 20.63%, and finally, reading errors of 0.79%. It can be seen that the female gender makes more mistakes by 57.14% compared to the male gender by 41.86%.

Abstract

Mathematics learning activities in schools tend to emphasize students to be able to solve problems with existing formulas. Likewise, teachers who pay less attention to and practice various problem-solving strategies. Thus, students are less able to express their thinking processes. This study aims to determine the students' mathematical thinking processes in solving mathematical problem-solving problems given. This type of research is descriptive qualitative with research subjects consisting of 6 students of class X Social Sciences SMA Islam Plus Adzkia Medan selected by purposive sampling method. The data collection technique was carried out using research instruments in the form of a description test which amounted to 3 questions and interviews. The results showed that the thinking processes used by students in solving problems were different. There are several problem-solving strategies used by students as a form of their thinking process. In the first question, there are three strategies used by students, namely act it out (conducting experiments), logical thinking, and different points of view. In the second question, all students used the strategy of registering all the possible answers that were explained directly or using the strategy of making tables. For the third question, there are two thinking strategies, namely by using formulas and strategies to find patterns. However, it was also found that there were still students who had inappropriate thinking processes.

Abstract

This study aims to describe the results of the study and examine the effect of the implementation of the Cooperative learning model on the students' mathematical critical and creative thinking abilities and obtain an effect size when viewed based on educational level, sample size, and research demographics from the primary studies being analyzed. This research is quantitative research with a meta-analysis research design. The research sample that met the inclusion criteria consisted of 34 primary studies of mathematical critical thinking ability (the total effect size of the studies was 39) and 23 primary studies of mathematical creative thinking ability (the total effect size of the studies was 24). Based on the research findings, it was found that the overall effect of the implementation of the cooperative learning model on the students' mathematical critical thinking skills had a significant effect with an effect size of 0.792. Overall, implementing the cooperative learning model on the students' mathematical creative thinking ability had a significant effect with an effect size of 0.696. In addition, there is no difference in mathematical creative and critical thinking abilities between the students who studied in the cooperative class and those who studied other than in the cooperative class in terms of education level and sample size. There is no difference in mathematical critical thinking skills between the students who studied in the cooperative class and those who studied other than in the cooperative class in research demography. However, there are differences in mathematical creative thinking abilities between the students who studied in the cooperative class and the students who studied other than in the cooperative class in terms of research demography.
