Abstract

Metaphor is a powerful cognitive tool to understand or develop mathematical concepts. Although metaphor has been progressively recognized in mathematics education, there is an inadequate systematic review of its application and achievement. Therefore, this study aims to investigate and map metaphors studies trends in mathematics education. Data were collected from a systematic review of 70 metaphor studies in mathematics education published from 2012–2021 using the PRISMA guidelines. The results showed the mapping of the metaphor studies' attributes in mathematics education. Future research can use this information as the basis for determining the novelty of research related to metaphors. Furthermore, they can use this information to determine its potential and opportunities for future research. The primary limitation of this review is related to the sensitivity of the search strategy, which makes it impossible to cover relevant studies comprehensively.

Abstract

The problem in this study is the limitations of mathematics learning media that are suitable for the conditions of deaf students. So, the researcher developed an assistive math teaching aid for deaf students. This study aimed to determine the effect of using assistive learning technology given to hearing impairment students. This research focuses on improving the representation ability of hearing impairment students on the topic of fractional operations. This research is a quantitative study with a pretest-posttest control design. This research was conducted on hearing impairment students with mild to severe categories without intellectual impairment. The number of hearing impairment students involved was 12 students at a special type B school in Magelang City, Indonesia. The N-Gain test was used in this study to measure the improvement in the representation ability of hearing impairment students. Based on the results of the study, it was concluded that assistive learning positively affected the representation ability of hearing impairment students. Based on the results of the N-Gain test, an increase of 0.972 was obtained. In addition, the use of assistive learning technology provides a learning experience that trains the independence of hearing impairment students. The teacher's role as a facilitator in the classroom can be maximized because topics can be accessed anywhere and anytime.

Abstract

This research aims to investigate the relationship between mathematics teachers' knowledge of STEM (Science, Technology, Engineering, and Mathematics) education and their teaching practice in schools during a STEM professional development program. The study involved 34 Indonesian mathematics vocational high school teachers enrolled in the STEM professional development program. Tests and reports on STEM teaching practices served as data sources for this study. Our finding shows a positive correlation between mathematics teachers' STEM knowledge and how they facilitate STEM project-based learning for their students. We discuss two different points of view to interpret this result. Furthermore, we suggest the need for further research to develop sustainable efforts in strengthening the STEM education interdisciplinary approach for the professional development of mathematics teachers.

Abstract

Several papers studied infinity from the difficulties that students and teachers show in developing the concept. For this study, it was considered the analysis of the equality 0.999 … = 1. Mainly, this research aims to show that a mathematics teacher presents erroneous conceptions just like a student; that is, both students and teachers have the same difficulties in the concept of infinity. To this aim, a semi-structured interview was conducted with an in-service mathematics teacher in Tlaxcala, Mexico. The purpose of this research is to exhibit a high school math teacher’s misconceptions about the concept of infinity. In general, misconceptions found here can be divided into four groups: without a clear picture of the concept of infinity, an infinite periodic decimal number cannot be a representation of a finite number, a decreasing infinite sum cannot lead to a finite number and an infinite process is limited in real life is finite and has ended. The results obtained were compared with those already available in references about the difficulties with students and teachers, finding that the results shown here are like those reported in the literature. This highlights the need to overcome the teacher’s conceptions of infinity in future research.

Abstract

Problem-solving skills are one of the core skills in mathematics learning; this skill helps the student be an effective problem solver. Conditions in the field show that the problem-solving skills of Indonesian students are currently low. This study aims to know the improvement of problem-solving skills and the description of that skill in terms of learning styles in problem-based learning assisted by Assemblr based on Javanese culture augmented reality. The research method used was a mixed method with a sequential explanatory strategy. Data collection techniques included tests, questionnaires, and interviews. Quantitative data were analyzed through statistical tests and groupings of student learning styles. Qualitative data analysis was carried out through data collection, reduction, presentation, conclusions, and triangulation techniques. This study used a one-group pretest-posttest design with a random sampling technique, and research subjects was selected by purposive sampling based on learning styles. Results show that there are no students with an auditory learning style. Students’ problem-solving skills increased with the n-gain score, which is 0.5 in the moderate category. In terms of learning styles based on Polya’s stages, show that students' problem-solving skills with visual, kinesthetic, and visual-kinesthetic styles are quite good. Students can understand problems, formulate problem-solving plans, and carry out formulations, but students with visual and kinesthetic learning styles are still not careful in calculations and re-checking answers, while students with visual-kinesthetic learning styles do not re-check their answers. Further research is expected to examine all learning styles, including auditory learning styles.

Abstract

Combinatorial thinking errors describe students’ difficulties and obstacles in solving combinatorial problems. This study aims to describe the errors experienced by students in solving combinatorial problems in terms of combinatorial thinking processes. This research involved two subjects who were 12th grade high school students at a school in Gresik, Indonesia. The students have already taken a combinatorics course. Data collection was conducted using the think-aloud observation method and task-based interviews. Both methods of data collection were conducted to validate the data using the triangulation method. The two subjects experienced similar errors. The research shows that the filling slots method is a simple and easy way for students to understand, but problems arise when students cannot understand the meaning of the questions and input the correct numbers for the problem. The combinatorial thinking error includes the general counting process and vertical upward formulas or expressions. The general counting process error is generating a number that represents the given aspects of the problem and the vertical upward formula/expression is identifying the concept that fits the problem. This research suggests enhancing students understanding of number representation when teaching the filling slot method. The teacher should illustrate some of the multiplication rule and addition rule examples to help students distinguish between these two fundamental rules. Further research is needed to provide solutions to the constraints experienced by students in solving combinatorial problems.

Abstract

The low percentage obtained by students in solving TIMSS problems, especially in the algebra material domain, shows that there are several mistakes that students often make in solving TIMSS-type problems. This study aims to examine students' errors in completing algebraic mathematics tests using the TIMSS (Trends in International Mathematics and Science Study). This was a qualitative descriptive research project in which students of a state junior high school in Sinjai, Sulawesi Selatan, Indonesia, in class VIIIA were the subjects. The research's study instruments included diagnostic tests and interview protocols, and data analysis procedures were separated into three parts: data reduction, data presentation, and conclusion, which involves drawing or verifying. The researchers discovered four kinds of students’ errors in completing algebra tests based on TIMSS that were connected to Newman's category: understanding question errors, transformation errors, process skill errors, and answer writing errors. Furthermore, the cause of errors in answering algebra questions based on TIMSS was that students do not pay more attention when writing information based on the following questions; they do not master the material related to the questions; they have a limited understanding of the material related to the questions; they also forget the concept of multiplication; they do not follow the procedures appropriately; and they do not re-check the answers. As a result, teachers must create TIMSS-based questions to help students improve their mathematical abilities.

Abstract

Most students are struggling in this new learning method and their engagement in learning math is deemed to be adversely affected due to limited interactions and accessibility in an online mode of learning, thereby affecting their motivation and achievement. Hence, this study looked into the domain of pedagogical competence of teachers that significantly influence students’ online engagement in the new normal. This study utilized non-experimental quantitative research design employing a descriptive-correlation technique to 100 junior high school students of the research locale identified through random sampling method. The research instrument of this study used two sets of questionnaires in accordance with its declared variables. Results of the data were analyzed using Mean, Standard Deviation, Pearson r correlation, and Linear Regression analysis. Descriptive results of the study revealed that teachers’ pedagogical competence and online engagement of the respondents both obtained a high descriptive level. Furthermore, inferential results of the study suggested there is no significant relationship between teachers’ pedagogical competence and online engagement of junior high school students in mathematics. Given these results, it is highly encouraged that the school must have constant teachers’ professional development programs that can strengthen the abovementioned significant pedagogical competence domains affecting the students’ learning engagement.
