No full textThis study aims to identify the attitudes of students on the ability to solve problems with mathematics. The attitudes of students evaluated in this study include self-confidence, anxiety, enthusiasm, and self-regulated mathematics learning. The research subjects were 79 students in grade VIII. The researcher re-concentrated on three students from all of them, who had mathematical problem-solving skills in the high, medium, and low groups. These subjects were selected from students who focused on problem-solving mathematical skills, questionnaires on the attitudes of students, and interviews with researchers. The instruments used to collect were an instrument of problem-solving mathematical ability and an instrument of students’ attitudes in the form of student attitudes towards mathematics questionnaire. The research method used is descriptive qualitative. The findings have shown that the majority of students are balanced between excited and unexcited on mathematics. The majority reason for students who are enthusiastic about mathematics is that they can improve their abilities, talents, and knowledge. Others have different explanations such as having the resources; formulas and problems, making them feel challenged; thinking that mathematics is important.

Atensi Siswa Dalam Menyelesaikan Masalah Fungsi
No full textThis study aims to describe the students' attention processes in solving functional problems. This research is a qualitative descriptive study, with subjects of 2 students taken from 8 students of secondary school. The results show that the students' attention process in solving functional problems was based on attentional characteristics, namely when students who answered correctly in solving questions and interview process, before and after reflection had complete cognitive attention structures. While students who answer incorrectly in solving problems have incomplete attention to cognitive structures, characterized by a lack of concentration in seeing the relationship between one mathematical object and another mathematical object. Attention characteristics in this study begin with recalling previous information and responding or giving feedback to problems by linking previous information with existing problems. Next analyze by breaking down information into smaller parts and easy to understand. The next step looks at the relationship between the decomposition process to get ways that can be used in the settlement process to obtain the final results that are part of decision making.Penelitian ini bertujuan untuk mendeksripsikan proses atensi siswa dalam menyelesaikan masalah fungsi.

EDUCATORS’ PERCEPTION OF BLENDED LEARNING MODELS ON MATHEMATICS LEARNING
No full textThe main objective of this research is to analyze and compare educators' perceptions of the application of the BL model in mathematics learning. The stages of research carried out in this study began with the manufacture of questionnaires both for educators and students. Next the researchers asked one of the lecturers and mathematics teachers to validate it. Based on the results of the validation conducted, the questionnaire was declared to be appropriate to be used by correcting a selection of words so it would not have a double meaning. In the next stage, researchers distributed the questionnaire to educators in schools and universities in several provincies in Indonesia After obtaining the data, researchers analyzed the data using WinStep. The results of the questionnaire showed that there was one question on the questionnaire that was difficult to be agreed upon by lecturers and teachers, namely the 16th statement that revealed students felt they needed more time to complete online assignments when dealing with graphics / diagrams / tables / other on mathematical materia
STUDENTS’ CRITICAL THINKING IN DETERMINING COEFFICIENTS OF ALGEBRAIC FORMS
No full textThis paper reports the study of the critical thinking skills of 7th-grade students in junior high school on determining the coefficients of algebraic operation. Data were collected using worksheet and interviews. 34 students were involved during the study. The study reveals that there were 35% students who performed algebraic operations correctly. Students’ difficulty is mainly on determining the coefficients associated with the algebraic forms. In general, errors occur in the process of finding algebraic solutions, explaining the reasons for the stages of strategies taken and drawing conclusions. This is due to the fact that the main attention was given to the final result of the process of working on algebraic form problems, and less focus was paid on giving reasons for the process of working on problems that stimulate the students to think critically
