Error in learning mathematics means an inappropriateness of someone in determining the solution of a problem, either in the concepts or its completion procedures. Semiotics means signs or symbols. The use of symbols is the concept of one's thinking in using symbols and representing certain meaning. Problem-solving...

The ability to think critically is an essential skill and becomes one of the primary goals in college. A person who can think critically will be able to use appropriate criteria to evaluate an argument. There must be clear evidence and accompanied by a plausible explanation.

This qualitative descriptive study aimed to describe the profile of understanding layer of the Conic Section concept toward Mathematics Education Students 2016 of FKIP UKSW. The understanding layer includes eight layers, Primitive Knowing (Pk), Image Making (Im), Image Having (Ih), Property Noticing...

Due to the abstract nature of mathematics, it is not possible to access mathematical objects without the use of representations. Representations can help to make mathematical ideas more concrete and available for reflection. Hence, they can help students to organize, record, and communicate their thinking....

Mathematical critical thinking is an essential ability for prospective teachers. The prospective teachers must be able to use the ability to think critically well so that students who are taught can also have good mathematical critical thinking skills. However, sometimes prospective teachers have a mistake...

The mathematical communication skill is an important thing to support the teachers’ role as facilitators in helping students to master 21st-century skills. The efforts to improve the skill must be well prepared since they are still as prospective teachers. The communication skill involves some aspects....

This study aims to describe the students' thinking interference of global type in solving permutation problem based on information processing theory. The subjects were 16 students of the Mathematics Department, Universitas Negeri Malang. The results showed that 50% of student’s experience global interference...

An endeavour to improve the quality of education have been made by improving the implementation of learning. The effort has not been enough to show satisfactory results. This can be seen from the mathematics learning achievement shown by the students still low. Based application PAMER UN 2017 by PUSPENDIK,...
