TL;DR: In this paper, the main objective of this research in the first year is to uncover the cause of the students error in resolving discrete mathematics by Newman Errors Analysis (NEA), which will be used as the basis for the subsequent research that reveal the mathematical creativity of students.
Abstract: This article is based on research cooperation of Foreign Affairs in the first year, which was carried out between the team of lecturers from the Department of Mathematics Education Unnes (Indonesia) with Dr. Chin Kin Eng, a lecture of Mathematics Education from Universiti Malaysia Sabah. The main objective of this research in the first year is to uncover the cause of the students error in resolving Discrete Mathematics by Newman Errors Analysis (NEA). The Results of this research will be used as the basis for the subsequent research that reveal the mathematical creativity of the students. Outcomes of this research is the publication of research results in the International Journal and seminar at the international level. As a qualitative research, data collection through an analysis of the results of tests, questionnaires, observations, and interviews. Data analysis are data reduction, exposure of data, synthesising the data, triangulation, and the inference/verification. According to research, known that students errors in resolving discrete mathematics caused by: (1) the student did not know the meaning of a symbol or an existing term in the problem (Reading Errors), (2) the student did not understand the meaning of the problem, namely the student fails to write what is known and what is being asked (Comprehension Errors), (3) students forgot a formula that will be used or strategy/procedure what to do (Transformation Errors), (4) students could not make the problem-solving algorithms in sequence and correctly (Process Skills Errors), (5) the student could not answer according to the question (Encoding Errors), and (6) the student could not translate well, especially about which was written in English (Language Errors). Errors caused by carelessness students (Careless Errors) was not found. After giving Learning Therapy for the provision to resolve a problem through the algorithm and the correct sequence, the causes of the error of some students could be minimized, so that the number of students who were experiencing errors could also be reduced. Results of this research became the basis for continued research in the second year, which will be revealed and developed the mathematical creativity of students with prepare advanced research instruments.

TL;DR: In this article, the authors describe the urgency of higher order thinking skills content analysis in mathematics textbook and find out how the HOTS content in textbook is used by teachers and students.
Abstract: Higher Order Thinking Skills (HOTS) is a skill demanded in 21st century. HOTS is trained in mathematics learning which one of its execution uses teaching materials such as textbook. This article aims to describe the urgency of HOTS content analysis in mathematics textbook. The results of literature review show that HOTS is one of the main goals in education and become one of the top five variables that can improve student achievement. HOTS can be developed but cannot be automated and requires practice. Textbook is one of the learning media that can be used in training HOTS because the textbook is the main learning media for teachers and students. Teacher's decisions in selecting teaching materials and strategies are also directly influenced by textbook used by teachers. Some studies even mentioned that there is a strong relationship between textbook used with student achievement. Thus, it can be said that the more HOTS content in a textbook, the greater the probability of HOTS to be trained and taught to the students. Therefore, a mathematical textbook analysis is needed to find out how the HOTS content in textbook is used by teachers and students.

TL;DR: The results of the study showed that the implementation of PBL had been more effective in comparison to the expository one in terms improving the students’ HOTS and the obstacles that had been encountered within the implementation were related to the teachers’ unpreparedness, the time allocation, the unequal students' input, theStudents’ learning habits and the difficult assessment.
Abstract: The study was to describe the implementation of Problem-Based Learning (PBL) toward the improvement of students’ Higher Order Thinking Skill (HOTS) and characters and to describe the obstacles that had been encountered within the implementation. The study was a mixed research that made use of concurrent mixed method design. The population in the study was the students from eight junior high schools that had been selected from six provinces in Indonesia namely the Yogyakarta Special Region, Bengkulu, South Borneo, West Nusa Tenggara, Southeast Sulawesi and Papua. There were 648 students who had been selected randomly from these schools. The researchers conducted the PBL process within the experimental classes and the expository learning process within the eight control classes. The data gathering process was conducted through the test, the self-assessment and the open questionnaire. The quantitative data analysis was conducted inferentially using multivariate and univariate analysis, while the qualitative data analysis was conducted descriptively. The results of the study showed that: (1) the implementation of PBL had been more effective in comparison to the expository one in terms improving the students’ HOTS; (2) the implementation of PBL had not been more effective in comparison to the expository one in terms of improving the students’ characters; and (3) in overall the obstacles that had been encountered within the implementation of PBL process were related to the teachers’ unpreparedness, the time allocation, the unequal students’ input, the students’ learning habits and the difficult assessment.
