Abstract

This research aims to describe the students’ metacognitive failure in constructing proof and the scaffolding support. The participants of this qualitative case study were eight preservice mathematics teachers of six-semester, State University of Malang. We carried out a test about proof construction problems in Abstract Algebra. Then we verified the data using triangulation of constant comparative method from a test and a task-based interview with the stimulated recall. The results indicated two groups of students in proving strategy.  Group I performed “appropriate” syntactic strategy and Group II vice versa. Blindness was experienced by the subject that does not recognize errors detection or the ambiguity of the proof. Mirage occurred when the subject recognizes an error detection on the proper strategy or application of a theorem, then is unable to verify the truth of his work. Misdirection appeared when the subject recognizes a lack of progress, then uses an incomplete or irrelevant concept. Vandalism emerged with no progress or detection of errors of the strategy then the subject performs some irrelevant steps to the issue or uses a misconception. Practically, the teachers can use these results for learning innovations in scaffolding-based proof courses. The scaffolding might need some development and application in supporting students to overcome difficulty in proving mathematical sentences.

Abstract

Teachers play a more significant role as a symbol of teaching success. Teachers who hold a more potential digital literacy in education teach mathematics with patterns and procedures, leading to practical teaching mathematics. Influential digital literacy and higher thinking are not possible when teachers do not use technology to understand the concept of mathematics. Therefore, teachers are required to improve their technical abilities and higher thinking in mathematics learning. This research used a cross-sectional quantitative research. This research uses statistical analysis of the Kaiser Meyer-Oikin Test (KMO) and the Barlett's Test to obtain exploratory factor analysis. Subsequently, the analyzed using confirmatory factor analysis and structural equation model with Analysis of Moment Structure (AMOS). The purpose of this research is to provide an overview of the relationship between higher thinking skills and digital literacy. The review discoveries show that teachers' digital literacy has a more significant impact on the use of technology in the classroom, and teachers' higher thinking in the role of technology will encourage teachers to use more technology in their practical teaching. Teachers need to broaden their perspectives on the ability and quality of mathematics teaching that is more easily changed by changing practical instruction in the classroom. One of the reasons mathematics teachers still apply traditional teachings is the lower thinking and low level of digital literacy. Teachers are not capable of teaching the concept of mathematics with technology to students.

Abstract

The synthesis of some empirical researches revealed that the implementation of problem-based learning (PBL) has a heterogeneous effect size on the mathematical critical thinking skills (MCTS) of primary school students in Indonesia. However, it seems that no researches were investigating the causative factors of the heterogeneity of primary students’ MCTS through PBL. Therefore, this meta-analysis research was employed to examine three potential factors that were PBL class capacity, PBL treatment duration, and mathematics topic predicted as the causative factors of the heterogeneity of primary students’ MCTS. The Q Cochrane test by using the Comprehensive Meta-Analysis (CMA) application was used to examine these potential factors. The synthesis of ten primary studies published in 2015 – 2020 and indexed by Scopus, Google Scholar, Sinta, and Web of Science, showed that PBL treatment duration and mathematics topic were the significant factors causing the heterogeneity of primary students’ MCTS. However, PBL class capacity was not a significant factor causing the heterogeneity of primary students’ MCTS. Thus, primary school mathematics teachers should consider PBL treatment duration established and mathematics topics selected in cultivating primary students’ MCTS by implementing PBL.

Abstract

This study aims to develop the valid, practical, and effective teaching instruments by using Creative Problem Solving (CPS) learning model with Somatic, Auditory, Visualization, and Intellectually (SAVI) based. This method of this study is RnD (Research and Development) which uses 4 D (Define, Design, Develop, and Development) learning model from Thiagarajan. But, this phase of the study is not spreading the developing result of the teaching instrument yet. This study produces learning instruments such as lesson plan (RPP), learning module, and students’ worksheet (LKS). The result of this study shows that 1) learning instruments by using CPS learning model with SAVI based such as lesson plan, learning module, and student’s worksheet includes in good category based on the expert judgement generally, 2) students and teacher’s response toward the learning by using CPS learning model with SAVI based show that they are interested in learning process, new learning model which is not used before, and they are also interested in the student’s worksheet and learning module, and 3) CPS learning model with SAVI based is effective to use in learning distance in space. From this result of the study, it can be concluded that the developed learning instrument is valid, practical, and effective.Keywords: CPS; Development;Learning Instrument; SAVI.

Abstract

The low ability of mathematical generalization of the students of SMPN 17 Bandar Lampung is because most of the students still have difficulty in drawing a conclusion from the material they have acquired and the lesson learned process of generalization aspect or less precisely the instructional model used. The purpose of this research is to know the influence of learning model of Peer Led Guided Inquiry and learning, discovery learning model with the ability of mathematical generalization. The measured variable from this research is the generalization ability in mathematics learning with the subject of algebraic factorization. This research is a quasi experimental research (quasi experimental research), where the subject of the study is students Class VIII students SMPN 17 Bandar Lampung. Data collection technique used is a test of mathematical generalization ability. The data analysis technique used analysis of variance (ANAVA) of one road with cell unlike the significance level α = 0,05 and as requirement analysis, that is a normal distribution population with liliefors model and homogenous population with Bartlett Test. Based on the result of research using ANAVA one way with cell unequal, hence the decision of Ho test is rejected. So it can be concluded that there is influence of learning model Peer Led Guided Inquiry, learning model of Discovery Learning, Conventional learning model to ability of mathematical generalization of learners. The test proceeds with a double-compression test using Scheffe ' methods to see which has a significant effect on mathematical generabilizability. The calculation results show that of the three treatments, the learning model of Discovery Learning which gives a significant influence on the ability of mathematical generalization.

Abstract

This research is motivated by the lack of learning media used by educators in the teaching and learning process, and the low interest and motivation of students. The purpose of this research is to find out how the feasibility of developing Geogebra-assisted learning media (modules) is a subject matter. The research method used is research and development (R n D) with the steps used based on Sugiyono. The steps taken are limited to seven stages: 1) Potential and problems, 2) Data collection, 3) Product Design, 4) Design validation, 5) Design improvements, 6) Product trials, 7) Product revision, due to time constraints - the research steps according to Sugiyono were not carried out by all. The results of the study were based on the results of the test of material experts, media experts and linguists, scores obtained in succession (4.08), (4.53), and (4.27), the Geogebra-assisted learning module was assessed for interesting and feasible categories to be used as learning media for high school class XI on the topic of derivatives.
