<![CDATA[Metacognition is an important concept in cognition theory, which can be interpreted simply as an attempt at what is thought. The purpose of this study was to determine the students thinking process in term of students metacognition skills in designing mathematics learning. The research subjects were 6 undergraduate students of mathematics education at Sanata Dharma University. The object of research is the learning process carried out by students. This type of research is descriptive qualitative research because data retrieval is obtained through projects and interviews then data is presented in the form of sentence descriptions. Research results show that students who have good metacognition skills tend to be able to design complete learning through directing awareness and regulating their thinking processes. Students who have poor metacognition skills tent to believe in the thinking process so that is does not carry out the process of metacognition on the steps to design mathematical learning. Through the design of learning students can be trained to direct their metacognition abilities. This metacognition ability cannot always be seen in the problem solving process.]]>

<![CDATA[This study aims to understand the profile of school mathematic problem solving skills of the students of Mathematic Education Program (PSP Matematika) in Widya Mandala Madiun Catholic University (UKWMM). This study is a descriptive-explorative qualitative research which involves 29 Mathematic Education Program students of UKWMM in the academic year of 2017-2018. The data are collected using Problem Solving Test of School Mathematics in the form of a subjective test which consists of 5 questions. The test is used to describe the profile of school mathematic problem solving skills of Mathematic Education Program students in UKWMM. The process of the students answering the problem solving test of school mathematics is also analyzed to describe the students weaknesses on solving the school mathematic problems. The result shows the students of Mathematic Education Program of UKWMM do not have good enough school mathematics problem solving skills. The analysis on the process while the students are answering the test also shows that most of the students are not accustomed to (or do not have enough experience on) solving problems that require higher order thinking skills. The students do not possess the strategy to solve the non-routine problems. The lack of curiosity and willingness of the students to solve the problem has become one of the factors that cause the lack of their mathematic problem solving skills. ]]>

<![CDATA[Immediate feedback is an appropriate strategy carried out by the teacher after evaluating student work. During this time the teacher only provides feedback with remedies and portfolio sometimes the teacher never gives feedback to students at all after learning is completed. Though feedback is actually a very important strategy in achieving optimal learning and to achieve student completeness, especially completeness in mathematical communication through the learning model of contextual teaching and learning. This is a concern of a teacher in mathematics teaching that is not in accordance with the objectives of teaching mathematics. The emphasis in this study is how is the role of immediate feedback in improving mathematical communication through learning Contextual Teaching and Learning?]]>

<![CDATA[Abstract : Working memory capacity (WMC) is important for many cognitive processes including problem solving. This research compiles relevant literature about working memory capacity and problem solving, and discusses how working memory capacity can help or hinder people when trying to solve problems, especially mathematical problems. Working memory capacity plays a role in maintaining and retrieval of information in long-term memory (LTM), but under certain conditions, this can have an effect on the success of problem solving. Working memory capacity can support more effective problem solving by activating the retrieval and use of information that is relevant to the domain. On math problems about simple arithmetic for example, problem solvers with high working memory capacity can show differences from problem solvers with low working memory capacity. The source of this difference indicates superiority in coding or mathematical fact-taking or knowledge structures in LTM, the ability to deal with interference from relevant and irrelevant information, the ability to focus on problems, and the ability to produce or manipulate representations of mental problems. Keywords: Working memory capacity, problem solving, mathematical problems]]>
