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
STUDENTS’ ABILITY TO READ STATISTICAL DIAGRAM
Full text linkReading diagrams is an important ability needed by college students, particularly to writing their thesis. This ability could help students in describing and communicating the results of their research. Conversely, the inability to read diagrams causes errors in interpreting the results of the research. This descriptive qualitative study aims to describe the ability of students to read diagrams in terms of gender differences and the tendency to choose problems between bar/line diagrams, and the reasons behind the difficulties for students reading diagrams. This study involved 25 students of Mathematics Education, University of Lampung. Research data were collected using test and interview instrument. The results showed that students’ability both male and female to read diagrams was classified as moderate, the ability to read bar charts of female students was higher than that of male students but the ability to read line diagrams of male students was higher than female students, female students tend to choose bar diagrams rather than line diagrams while male students tend to choose line diagrams rather than bar diagrams, and the cause of difficulties in reading diagrams for female students were errors in understanding the meaning words while male students were errors of logical thinking in associating data with other data.Membaca diagram merupakan salah satu kemampuan penting bagi mahasiswa, terutama saat mahasiswa menyusun skripsi.

Analisis Sikap Siswa terhadap Kemampuan Pemecahan Masalah Matematis
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. The majority of students had a low category of self-confidence and anxiety towards mathematics, and had a moderate level of enthusiasm in mathematics and self-regulated learning.
 
PROFESSIONAL TEACHER PROGRAM EXPERIENCE: TEACHERS’ KNOWLEDGE ON OVERCOMING STUDENTS’ MISCONCEPTION
Full text linkThis study aims to describe the teachers’ knowledge about students in dealing with misconceptions experienced by the student on integral material based on the experience of teachers participating in the teacher professional program (PPG). This research is qualitative research that involved two subjects who were mathematics teachers of SMA Negeri 11 Ambon. Subjects were given a chance to identify the student's misconceptions. The data is collected through observation and interviews. Based on the research results obtained information that S1 has good knowledge in diagnosing misconceptions when use three tiers test, providing treatment when the student got a different answer, and ensuring that misconceptions do not occur in student with made peer instruction in front of the class, and have a good understanding of concepts about means of constant on indefinite integral. S2 cannot diagnose misconception and S2 cannot explain the different answers when the student solves the problem using a different method. Thus, it can be stated that teachers who have the PPG experience have a better knowledge of knowing and addressing the misconceptions experienced by the student
