Abstract

Digital transformation is changing teacher competencies that students need to succeed. It is increasingly important for teachers to develop their digital maturity in this context proactively. The emerging research on teacher digital maturity development has largely ignored the possible role of teachers' perceptions of large-scale changes in mathematics teaching using technology, especially in geometry learning. Several studies have explored digital video technology in geometry learning as a supporting tool for teachers' digital maturity in mathematics teacher education. Previously, usually limited visibility in teaching to the production of static images and film clips of educational orientation, then with the advent of dynamic geometric systems, the pedagogical community gained movement as a new publicly available means of teaching mathematics of teacher digital maturity in geometry learning. We did the survey using keywords related to geometry learning and digital technology. We have surveyed several pre-service Mathematics Teachers on geometry learning. The analyzed papers have provided insight into maturity model dimensions were extracted and consolidated into a maturity model framework. The consolidated maturity model framework consisted of five stages: initial, managed, defined, predictable, and optimizing. The results show core competencies in digital maturity level, namely integrating digital technology in teaching processes (optimizing level), adjusting and applying different teaching methods (optimizing level), developing a standard model for digital teaching abilities (optimizing level), establishing effective assessment items and models for assessing digital teaching abilities (predictable level), and setting paradigms for outstanding teaching abilities (predictable level).

Abstract

One thing that needs to be considered in the thinking process is the ability to make decisions. Decision-making includes probabilistic thinking. Decision-making is usually done after going through a series of processes. This study discusses how mathematics student decision-making is based on self-efficacy in probabilistic thinking. This research is descriptive qualitative research. The validity of research data with triangulation techniques. The results show that decision-making in probabilistic thinking requires a series of processes, namely understanding the problem, having initial intuition, choosing the right strategy, doing numeracy, then evaluating, and then making a decision. For subjects who have high self-efficacy, the subject makes decisions that fulfill all the elements in decision making. Subjects with self-efficacy are in the decision-making process, the use of numerical concepts is still not right, but the other elements have been met. For subjects with low self-efficacy abilities, they are still less precise in initial intuition, numeration, and final evaluation so the decision making is still not right.

Abstract

Researchers in the field of mathematics education are also growing. This makes research on article reviews very important to do, because it can help researchers in determining the research to be carried out. In this study, a review of research articles on dynamic thinking in mathematics education was carried out. Researchers have investigated dynamic thinking, but what is being studied is diverse. The purpose of this article is to provide an overview of dynamic thinking discussed in mathematics education research. In this study, we analyzed 22 articles published from 1999-2020 with systemtic review. We have searched for articles in the Web of Science database assisted by harzing's publish and perish software with a single keyword or keyword combination. Keywords or combinations of keywords used include dynamic thinking, dynamic of mind, a combination of dynamic thinking and mathematics. We have conducted a systematic review inductively finding dynamic thinking that is discussed in mathematics education. We found that there are still many things that have not been researched by researchers. Researchers are mostly from the United States and Canada. This article also provides an overview of the research of dynamic thought processes whose different focal points are cognitive processes (information processing, abstraction, restructuring, imagination, perceptual decision making), thinking, cognitive abilities, cognition, fMRI, environmental influences, and movement.

Abstract

The research was motivated by the results of previous research, namely that students only reached level 2 of Van Hiele's geometric thinking ability and the motivation for student achievement was low. So that the PARAS learning model was chosen, namely the modification of problems based learning and the ARCS model. The purpose of the study was to determine the effectiveness of the PARAS learning model on the ability to think geometry and motivation for student achievement. In this research design One-group Pretest-posttest Research Design. The population is mathematics education students of Bina Bangsa Serang University for the 2021-2022 academic year. The sample was selected using the purposive sampling technique, namely the second semester students, totaling 22 students. Data collection techniques with geometric thinking ability tests before and after learning and a questionnaire of motivation to excel after learning. The data analysisis the effect size test, percentage, chi-square test and contingency coefficient. In conclusion, it is known that the effectiveness of the PARAS learning model on students' geometry thinking ability is very high and students have been able to reach the deduction level. For the motivation for student achievement after being given learning with the PARAS learning model, it is concluded that the average is relatively high. Furthermore, it is known that there is no relationship between the motivation to excel and the student's geometric thinking ability. The implication of this study is a modified learning model that can improve the ability to think geometry and motivation for student achievement.

Abstract

This research aims to identify and analyze students' critical thinking skills and learning barriers in learning mathematics translation material. The concept of translation is fundamental for students who want to master geometric transformations. Students must understand the basics of translation because this understanding of translation will be needed at a higher level. However, many students still experience obstacles in understanding translation material. Students experience learning impediments because of the difference between the expected achievements of critical thinking skill indicators, interpretation, analysis, evaluation, and inference, and the actual results. This research uses a qualitative descriptive research methodology, utilizing data collection techniques such as interviews, observation, and documentation. Data analysis was conducted using descriptive methods with 30 class XI-1 students as participants. Triangulation was used in the data collection process, which involved using teacher and student interviews, administering diagnostic tests, and textbook analysis (document analysis). The research results show that the average percentage of students' critical thinking abilities from the four indicators is 41.665%. Ontogenic, didactic, and epistemological barriers cause the low critical thinking skills of class XI-1 in studying translation. The research results can be used as considerations for teachers in designing learning to improve critical thinking skills and reduce students' learning barriers in learning translational material.
