Abstract

The purpose of this research is to describe the process of thinking interaction of students in solving the open-ended problem. The thinking interaction of students' in this study is defined as an activity of exchanging thoughts between students one with other students through communication to produce the suitability of the thinking process between them through the resolution of open-ended problems. This study was conducted on a group of junior high school students with heterogeneous capabilities, consisting of 5 students, and have taken the material to build space. The data of thought interaction activity is obtained from discussion result in solving open-ended problem analyzed by information processing theory. Students' thinking interaction activities begin from one subject person who gives statement and understanding about the problem provided. Activity mutual ideas, complement or give feedback to other subject's comments, ask questions that have not been understood, or give an explanation in deciding the answer to be agreed. Subsequent activities decide the answer orally to be written by each subject. All subjects poured the agreed result on the answer sheet, but there were still doubts from the two subjects on the answer, so the subject looked back at the answers from other subjects. Some subjects continue to write answers and in the end, each subject has a form of answer in accordance with their respective understanding.

Abstract

Imitating performance is not a mediocre element, yet it is a unique ability possessed by humans. Researche concerning on imitating performance has been widely conducted in early childhood education and in adults educations. However, imitating performance studies related to elementary school context is rarely explored. This study was intended to figure out the imitating performance of 5th grade student. This study was analyzed qualitatively where the researcher involved in all stage of the research. The results of the research indicated that there were few imitating performance indicators that were not fullfiled. The students were not able to apply the examples in the new context, in other words the students had failed in applying the examples. Consequently, they faced difficulties in communicating the solutions of mathematical problems.  Instead of helping the students, the key words provide by a teachers make the students confuse in resolving different problems.

Abstract

The purpose of this study was to describe the initial conception of prospective teachers about creative thinking in mathematics. This research used a qualitative research method. The Research was conducted at private universities in Semarang, held in the second semester of the academic year 2016/2017. The subjects were six students of the seventh semester. This research used two instruments; test to explore the concept of creative thinking and interview. This study provides findings that there are similarities in the concept of prospective teachers in mathematical creative thinking. The prospective teacher's conception of the creative thinking of mathematics leads to the emergence of new concepts or ideas in completing mathematical problems based on experience. The appearance of the new idea in question is to solve a different problem from the existing procedure and solve the problem with a different perspective that is still logical. The prospective teacher's said that it was necessary for prospective teachers to understand the concept of creative thinking in mathematics to solve mathematical problems from various perspectives based on his learning experience.

Abstract

This study was initially based on the researcher?s interest in a case found in students as they responded mathematical problems provided in the form of critiques to a problem. The study aimed to explore the students? arguments to describe the students? thinking processes while they are giving critiques to a mathematical problem. The study was qualitative research in a case study involving one student as a subject of research.  The finding showed that the students used 4 series of arguments as the main reason to give critiques to the given problem. The critiques were delivered due to several factors consisting of; (1) the students? inability to discover appropriate strategies to deal with the given problems; (2) the personal experiences kept in a Long Term Memory, and (3) the fallacy on reasoning.

Abstract

This research aims at describing students? statistical reasoning in graphics statistics representation related to distribution. The subjects of this research were students of semester IV of Program of Study Mathematics Education of Muhammadiyah University Ponorogo who have taken a basic statistics course. These subjects were chosen because they have taken a course related to descriptive statistics which discusses graphics representation and data distribution. The data collection technique used essay test related to graphics representation. In addition, an interview was also conducted to confirm students? answer. This research finding shows that statistical reasoning of semester IV students of Mathematics Education whose statistics ability is poor belong to pre-structural level and whose statistics ability is high belong to multi-structural and relational level. The high skilled students could conclude the data with statistical reason even though they used informal terms. Students with multi-structural and relational level regard that variety is a standard showing the numbers of different data among others, not on the different value from the average. Students with relational reasoning level were able to generate graphics concluding by connecting the central tendency and distribution scale.

Abstract

This research examines about gestures that can be used in learning math in the classroom to strengthen the understanding of students of the material being taught teachers, in this article, I showed the evidence taken from the teacher and the student movement for proving that mathematics can be realized. This research is descriptive research with the kind of data analysis on the research of these video recordings of teachers who carry out learning and research subject processed there are 2 teachers from 5 teachers are observed. We present evidence for a student and a teacher produces gestures when they explain the concepts and ideas of mathematics. The results of this study suggested that gestures have the power so that children quickly understand and understand the learning delivered teacher, and any gestures each had a special movement such as; (a) strengthened understanding pointing gestures students through movement within the physical environment, (b) strengthen representational understanding gestures students through mental simulation, action and perception, and (c) empower students through writing movement action be evidence of permanent marks on a sheet of paper, a whiteboard or visual media. Thus, the teacher's gestures are very important because it can strengthen the understanding of students of material studied in class.

Abstract

The trends of teaching mathematical thinking and the existence of two thinking skills (critical dan creative thinking) the required by 21st-century skills have created needs for teachers to know their students? thinking processes. This study is intended to portray how mathematics teachers expect their students showing their thinking processes in students? written work. The authors surveyed Whatsapp and Telegram group of mathematics teachers. First, the authors shared the result of the literature review and the governmental regulations about the need to develop thinking skills. Second, the authors stated that the potentials of students? written works as a tool for knowing students? thinking processes. Third, the authors sent a simple mathematical problem with the topic of algebra and asked the mathematics teachers how should their students answer that problem such that they can easily monitor and assess their students? thinking processes. A total of 25 teachers participated voluntarily in this survey. Results of the survey were triangulated with direct trial data in lecture classes at both undergraduate and postgraduate levels. The result indicates that participating mathematics teachers do not expect too much for their students to show their thinking processes in written work. Teacher?s focus is mostly on the accuracy and the correctness of their students? mathematics answer.
