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

Number line material is an essential material in learning mathematics. However, in fact some students experience difficulties in the learning process of number line material. As was found among students at the Graha Asuh Jabal 165 Foundation, only seven of twenty five children said they liked mathematics at the Al-Hilal 3 Sarijadi Foundation. Based on the problems found, this service activity aims to help students understand number line material. The method for implementing this activity consists of three stages, namely: (1) the activity planning stage; (2) implementation stage; and (3) evaluation stage. The results obtained in this service activity are in the form of post-test results which show that there is an increase in student responses from the results of the pre-test conducted at the beginning of learning.

Abstract

This study aims to analyze one of the mathematics textbooks published by the Ministry of Education and Culture. Then, the researcher will provide recommendations regarding the presentation of easy-to-understand material based on analysis of techniques, technology, and theory on each problem given by students' mathematics textbooks. This type of research is qualitative with a didactic anthropological theory approach, especially in praxeology. Data collection techniques in the library by reading, recording and processing these sources as research material. Researchers choose books based on the criteria needed to obtain relevant data. These criteria include (1) there is a problem in presenting mathematical material, (2) there is an author's name, and (3) publications from the Ministry of Education and Culture. The researcher found problems in the 2017 revised edition of class XI students' mathematics textbooks finding formulas and examples of arithmetic and geometric sequences. The study results showed several problems presenting the material for arithmetic and geometric sequences, which would raise student learning barriers. The identified Learning barriers are ontogenic, epistemological, and didactical obstacles. With these obstacles, the researcher provides alternative designs which are expected to minimize the occurrence of student learning barriers. So that the design alternatives provided can reduce obstacles for students in thinking and understanding the material of arithmetic and geometric sequences
