Abstract
Metacognition as knowledge and cognition on cognitive phenomenon and one’s own knowledge on his self-cognitive processes and use of this knowledge in order to monitor cognitive processes. Metacognitive skills refer to a person’s procedural knowledge for regulating one’s learning activities including problem solving. Word problems in mathematics have been vastly included in educational literature mainly due to the fact that the issue is considered to be one of the most difficult in math lessons. This research aimed at investigating the contribution of students’ ability to metacognitive thinking to metacognitive thinking skills in the aspects of prediction, planning, monitoring, and evaluation through the provision of mathematical words problems. The data was collected through tests, Metacognitive Awareness Inventory (MAI-Jr-Modified) observation sheets and interviews. The results of the study showed that the score of students metacognitive ability was 75.80 which contributed to the level of students metacognitive thinking skills at 78.98% in the high category based on the four aspects of metacognitive skills namely 78.13%; 81.25%; 84.38% and 71.88%. Learning through the provision of mathematical problems in the form of words problems can develop students metacognitive skills.

Published: November 2019

Abstract
Learning is often seen as developing academic abilities and achievement through formative assessment. Students always hate their ‘failure’ and are not as happy as students with better theoretical results. Equally important is the fact that undue emphasis on results rather than the process is likely to scare students from originality. Taking risks without fear of failure is the foundation of creative effort. This study used qualitative research methods, and the research subjects are students of mathematics education in a class of Differential Equations. This article shows two processes in evaluating learning, with the aim of seeing how students see a mathematical problem based on the question of the problem. One student class is given an issue clearly and leads to one answer, and at another time the question is presented again with questions by emphasising the role of creativity in learning and skills development. Of the two results of the work will be seen in how students face a mathematical problem. How to think convergent and divergent affect learning outcomes, and what factors need to be developed to make students feel more creatively.

Published: November 2019

AbstractPre-service mathematics teachers need to understand the school mathematics curriculum in order to ensure their capability as future teachers. As a learning planner, they have to possess an adequate understanding of what and how the school mathematics materials should be organized to fit the students’ need. The current Indonesian curriculum challenges the teachers to design mathematics learning which integrates four domains of competence, namely the spiritual attitude, the social attitude, the knowledge, and the skill. However, there has been no textbook available to guide the pre-service mathematics teacher designing the desired mathematics learning better. This research aims to develop a textbook for mathematics curriculum analysis, especially for senior high school level. It was an R&D using Plomp model stages, including initial investigation, design, construction, and test, evaluation, and revision. In the final stage, we have successfully developed a valid project-based learning textbook for mathematics curriculum analysis.

Abstract
Mental construction in this study is mental construction based on APOS theory (action, process, object, schema) in conducting mathematical proof. Therefore the purpose of this research is to find out how mental construction is based on APOS theory in mathematical proof and the results obtained from its application. This study included a quasi-experimental with posstest only nonequivalent comparison group design. This study conducted at IKIP PGRI Bali. The research sample was students who took real analysis courses. Based on the sampling results obtained two classes. Data retrieval is done by direct observation and tests. Based on the observations, it shows that the student worksheet is able to make all students active in learning. Data analysis shows that the mental construction of students proving ability is only up to the object stage. Based on the whole test results, the experimental class achieved significantly better results compared to the comparison class. This shows that the mental construction of students in proof has not yet reached the schema stage, which means that it needs to be improved and the application of APOS learning is able to help students in mathematical proof.
