The main obstacle is the difficulty of finding the literature in the appropriate journal form. This problem becomes important, because it will affect the continuity regarding the study period of students, and it will affect the college and future students concern as well. Therefore, a learning model that is oriented to review the journal as the main activity needs to be applied, while the appropriate model is Research based learning. Thus optimization of journal review on the learning activities can assist students in completing the thesis proposal.

This descriptive qualitative study involved 32 students from the Department of Mathematics Education. The result showed that subjects who were non-critical thinkers exhibited carelessness in understanding, recognizing errors, and overviewing the tasks because they believed that mathematical tasks are always right and problem-solving with formulas and procedures results in correct solutions. On the other hand, critical-thinker students were more careful in comprehending the tasks, checking the errors, and doing an overview. The belief that mathematical tasks can contain errors and that conceptual understanding is highly crucial in mathematical problem-solving increased the tendency of the students to think critically. Besides, the students also had to highlight that numbers in mathematical pro...

To make quality math assignments requires knowledge from the teacher about content and students, who are subdomains of mathematical knowledge to teach. This knowledge needs to be developed in prospective mathematics teachers since programmed teacher education. By focusing on one of the basic concepts in mathematics, namely the concept of function, research was conducted on 25 mathematics teacher candidates. Through interactions that occur in modified focus group discussions, we want to find out how prospective teachers construct knowledge about the concept of functions and difficulties of students. The results showed that in constructing the concept of functions and difficulties of students, teacher candidates worked backward, there were gaps in changing from one representation to another and identifying that the mastery of students' pre...

Students were asked to do parallelism exercises presented in a verbal and picture form. The data were analyzed by knowledge representation theory based on meaning and perception. There were students who have amodal-multimodal-transition hypothesis. Students' assumptions about the verbal and picture information of not-perfectly-drawn parallel lines varied: assuming that angles appear to be the same measure are congruent, the two lines would intersect, considering the two lines parallel but redrawing picture to determine the pair of congruent angles and using other perspectives to interpret the picture. This study recommends action research for geometry learning that provides not-perfectly-drawn parallel lines for students who have amodal and amodalmultimodal- transition hypothesis and observe its effect on their non-Euclidean geometry learning. ...

Through a case study approach, as many as 112 prospective mathematics education teachers from Universitas Negeri Malang of Indonesia participated in this research. researchers use test, interview and research sheet instruments as data collection tools. Then an analysis is carried out so that the following categories are obtained: subjects that symbolically express algebra, pictorial, and geometric. The results obtained that some subjects express symbolically algebra (83 of 112 subjects), while some subjects expressed pictorially (17 of 112 subjects), and geometrically (12 of 112 subjects). The research findings show that there are three forms of representation raised by the subject in expressing algebra, namely the representation of algebraic symbols, image representations, and geometric representations.

The data collected are in the form of words obtained through interviews, pictures of the results of the subject’s work, and the results of the mathematics anxiety questionnaire as an instrument for selecting subjects. Description of data analysis and interpretation of the meaning of the findings apply text analysis. Analysis is conducted in all phases of problem-solving including the phase of understanding, analyzing, exploring, planning, implementing, and verifying. The presence of metacognitive blindness is identified through red flag, which is a warning sign to stop or retreat to the previous problem-solving phase and immediately take certain actions. Three types of red flag identified in this study include lack of progress (LP), error detection (ED), and anomalous results (AR). The results of the analysis show that students who experi...

This qualitative descriptive study was aimed at tracing critical thinking skills of 25 students of elementary school teacher education program in the process of making mathematical problems. Students were given the task of making problems on the topic of the triangle. Furthermore, an interview was conducted to explore the process or reason for making the problems. The results of this study indicated that students had not been skilled at critical thinking in making problems. The activity of critical thinking in the process of making problems only included determining the focus of the problem and decision making. Nevertheless, the decision which was taken was not based on logical reasoning. The activity of examining the accuracy of supporting data and reflecting on problems had not been accomplished, so as to produce incorrect problems. Thus, critical thinking is of urgency to produce...
