Authors:Rizki Ahid Nurhasanah, St. Budi Waluya, Iqbal Kharisudin Pages: 115 - 121 Abstract: This study aims to describe mathematical communication ability based on math anxiety in 10th grade student. This research method is descriptive qualitative. The research subjects were 36 students of class X MIPA 5 at SMA Negeri 1 Lasem in the academic year 2020/2021. The research data were collected through questionnaires, tests, interviews, and observations. The data analysis technique in this study was done through a process of reduction, categorization, and data validity. Based on the results of the study, there were students who had high, moderate, and low math anxiety. Mathematical communication ability of students with moderate and high math anxiety, there is the fact that there are those who master writing problems into mathematical modeling, solving mathematical problems, and making a settlement conclusion; some only mastered writing mathematical problems into mathematical modeling but did not master solving mathematical problems and making a settlement conclusion; there were also those who mastered writing mathematical problems into mathematical modeling and solving mathematical problems but did not master making a conclusion. Meanwhile, students' mathematical communication ability with low math anxiety mastered writing mathematical problems into mathematical modeling, solving mathematical problems, and making a settlement conclusion.

Authors:Ranggamurti Iswara, Nuriana Rachmani Dewi, Adi Nur Cahyono Pages: 122 - 128 Abstract: There are five standard processes in learning mathematics, one of which is connection. In SMK mathematics learning, the ability to connect mathematics is needed by students, namely in mathematics itself, in subjects other than mathematics, as well as in solving real-life problems. Mathematical problem solving requires the ability to connect mathematics to able to connect between mathematical ideas to find solutions to problems. Self-confidence is one of several character values that are cultivated in learning. To face a problem requires an attitude of confidence in one's abilities. This attitude can affect students' motivation and performance in mathematics learning. Thus, the ability to connect mathematics and self-confidence have an important role in learning mathematics. The purpose of this study was to determine whether the PREPROSPEC learning model was effective in terms of the students' mathematical connection abilities. This research is a type of mixed-method research. The research design the researchers chose was quasi-experimental. The population in this study were students of class XI SMK Negeri 1 Purbalingga majoring in TKJ 2020/2021 academic year. The results showed that the ICT-assisted PREPROSPEC learning model was effective on the student's connection ability. This learning model has the advantage of being more flexible in its application. In addition, the additional use of ICT is expected to help students develop mathematical connection skills more easily. PubDate: 2021-12-30 Issue No:Vol. 10, No. 2 (2021)

This research method is mixed-method research with a sequential explanatory design. The research population is class VIII SMP Futuhiyyah Mranggen Academic Year 2020/2021. The sampling technique of self-regulated learning uses simple random sampling by taking 6 subjects. The results show that students with high Self-Regulated Learning can have a smooth flow of thought, can produce uniform ideas, can give answers that are different or unusual from the others, and can develop, add, and enrich an idea. Students with Self-Regulated Learning can have a smooth flow of thought and can develop, add, and enrich an idea. Students with low Self-Regulated Learning are only able to have a smooth flow of thought. PubDate: 2021-12-30 Issue No:Vol. 10, No. 2 (2021)

Authors:Krisno Budi Prasetyo, YL. Sukestiyarno, Adi Nur Cahyono Pages: 136 - 143 Abstract: This research aims to develop an APOS content-basic algebra for autonomous learning to achieve the mathematics connection skills that meet the instrument validity and implementation effectiveness criteria. The module included the basic concept of basic algebra as the learning reference for learners. Thus, learners could refer to the materials autonomously. The module was arranged systematically and complemented with detailed stages. They could facilitate the readers to act and to try the process of analogy. A similar stage also occurred on an object, the new problem, to create a theoretical framework in the form of a scheme. This research used a research and development design. The stages were defining the algebraic problems, designing the APOS-based module, creating a product draft, validating the module, and examining the effectiveness. The researcher conducted the field test with the learner representations from primary school, Junior High School, and Vocational High School. The research variables were learning autonomy and mathematics connection skills. The research used questionnaires and tests to collect the data. The data were then analyzed descriptively analytically. The experts' judgment obtained a score of 4.08, with a valid criterion. Then, the product was tested for the learnersâ€™ representations. The results showed their learning autonomy achieved scores of 73 (the primary school learner), 75 (the JHS learners), and 81 (the VHS learners). On the other hand, the mathematics connection skill scores were 75 (the primary school learner), 80 (the JHS learners), and 85 (the VHS learners) It showed that learning with the APOS content module had positive responses and achieved the expected results (effective).

Authors:Fattayati Fattayati, Masrukan Masrukan, Dwijanto Dwijanto Pages: 144 - 150 Abstract: This research aims to find students' creative thinking skills by learning Problem Based Learning assisted by Google Classroom in terms of Goal Orientation. This research is a mixed method type of concurrent embedded design with a quasi-experimental quantitative research design. The research subjects were students of class X SMAN 1 Purwodadi Grobogan. The results obtained are that students with the mastery goal category can achieve the four indicators of mathematical creative thinking skills, namely fluency indicators, flexibility indicators, detail indicators, and authenticity indicators while students with performance goal categories can only meet two indicators of mathematical creative thinking ability. The indicators of flexibility and authenticity are not met. Students with the mastery goal category tend to have a high independence character, while students with the performance goal category tend to have moderate or even low independence characteristics.

Authors:Hendra Yulianto, Dwijanto Dwijanto, Mulyono Mulyono Pages: 180 - 187 Abstract: The purpose of this study was to describe students' mathematical creative thinking skills based on field independent and field dependent cognitive styles. The research uses mixed research methods with a concurrent embedded strategy. The population in this study were class VIII students of SMP Negeri 1 Sengah Temila in the academic year 2020/2021. The sample selection used cluster random sampling technique and obtained class VIII A as the experiment class and class VIII C as the control class. The final data analysis of the quantitative research used the right-hand average difference test and the normalized gain test. Final data analysis of qualitative research with data triangulation. The results showed that field independent students met the aspects of mathematical creative thinking skills. Field independent students are very interested in the new concepts learned, understand the given structure, good analytical skills and can work independently. Then the field dependent students also meet the aspects of mathematical creative thinking skills. Field dependent students are quite interested in the new concept being studied, do not understand the given structure, use an experiential approach to solving problems, and tend to require guidance and direction to solve problems.
