Abstract

Students' ability in Indonesia has decreased due to the COVID-19 pandemic, so the Government provides solutions to restore learning in Indonesia through a Merdeka curriculum. The impact on schools, especially mathematics subjects, decreased mathematical problem-solving abilities. The decreasing ability of students to solve problems requires a test instrument based on the SOLO taxonomy. The formative research model is the type of this research. The stages in the model are preliminary and formative evaluation. Stages such as self-evaluation, expert review, one-to-one, small group, and field tests are the stages in formative evaluation. Based on the validation results of the four validators, the average score of the material aspect validation results is 94% with a very valid category, the average score for the constructed aspect is 87% with a very valid category, the average score for the language aspect is 92% with a very valid category, and the average score of all aspects is 91% with a very valid category so that the test instrument developed is categorized as very valid. The trial subjects in this study were conducted at SMAN 15 Pekanbaru, SMAN 12 Pekanbaru, MAN 3 Pekanbaru and SMA Plus Pekanbaru. Quantitative data is used as data analysis in this study. The research results that have been carried out from 20 questions, obtained from as many as 18 questions based on the SOLO taxonomy, have been tested and declared valid and reliable with a Cronbach's Alpha value of 0.871.

Abstract

Like in proving, teachers have an important role in critical thinking because critical thinking is not an innately given skill, rather, it is acquired later in life. However, at this point, educators have a lot of responsibilities because if the individual can transfer critical thinking to his life at school age, he can live his life more meaningfully, be inquisitive and find solutions to problems after school. For this reason, the opinions of teachers and hence prospective teachers concerning both critical thinking and doing proof are important. In this study, survey and correlational research methods were used together since it was intended to explore the views of pre-service elementary mathematics teachers regarding critical thinking and doing mathematic proof and to understand whether these two correlates. The study was carried out on 158 pre-service elementary mathematics teachers enrolled in a state university in the Eastern Black Sea Region of Turkey. According to the results, the pre-service teachers in this study have a low level of critical thinking disposition. service teachers depending on the grade level at which they were studying. When the participating pre-service teachers’ opinions on mathematical proof were examined, it was noticed that mental process was the highest while self-confidence was the lowest.

Abstract

One of the important materials to study in a trigonometry course is the value of trigonometric functions in standard positions. However, the results of preliminary research show that there are still many first semester students who experience errors in determining the value of the trigonometric function in the standard position. These errors are important for further analysis. Therefore this study aims to describe the mistakes of the first semester students in determining the value of the trigonometric function in the standard position. This type of research is a qualitative descriptive study with a case study approach towards students of the mathematics education study program at a university in Malang. The data collected in this study consisted of the subject's work and transcripts of interviews with the subject. Work data were analyzed descriptively to know the types of student errors. The transcript data from the interview results were analyzed by coding, to determine the factors that caused student error. The results showed that out of 34 students who made errors in determining the value of trigonometric functions at the standard position, 11% had conceptual errors, 56% had principle errors, 15% had calculation errors and 18% had factual errors. The results of this study contribute to teaching the material for the value of trigonometric functions in the standard position to reduce conceptual errors, principle errors, calculatin errors, and factual errors.

Abstract

This study aims to investigate the effectiveness of the GeoGebra-assisted 5E learning cycle toward students’ understanding of mathematical concepts. This study was a quasi-experiment with a pre-test and post-test control group design. The cluster random sampling technique was used to select samples from each group, which included 25 seventh-grade students. The data collected in this study were students’ mathematical prior knowledge obtained by giving objective tests before starting the learning process and students' mathematical conceptual understanding obtained by giving an essay test at the end of the learning process. The hypotheses were tested using a t-test. The findings revealed that the GeoGebra-assisted 5E learning cycle has an advantageous effect on students' comprehension of mathematical concepts, where t = 16.50* and p = 0.0001. The findings of this research implied that the GeoGebra-assisted 5E learning cycle model can be used as an alternative learning model to improve students' understanding of mathematical concepts.

Abstract

This paper aims to describe an innovative Teacher Professional Development Program (TPDP) to develop pre-service mathematics teachers’ curriculum knowledge. The participants of this study were eighteen pre-service mathematics teachers who have not learned about curriculum as a course in their teacher education program. Two different instruments to measure Pre-Service Teacher Curriculum Knowledge in the domain of statistics and algebra were delivered before and after the TPDP. The innovative TPDP for pre-service teachers in this study considered the current school mathematics curriculum as an entry object of learning. Furthermore, the triangle object such as the development of curriculum among countries, essential mathematics content, as well as designing lessons were elaborated in the model. The developed TPDP and pre-service teachers' lesson designs were described and analyzed qualitatively to see the pre-service teachers' curriculum knowledge. The result of the study shows that there is an improvement in Pre-Service Teachers' Curriculum Knowledge in almost all the components of Curriculum Knowledge, except basic skills and concepts. This implies that for designing a lesson plan, pre-service mathematics teachers need to carefully understand the school mathematics structure as a whole in a brief before the basic competence is reviewed.

Abstract

This research is an ethnomathematical research that aims to explore the mathematical abilities of the Bugis people in weaving the lipa’ sabbe. This study applies a qualitative method with an ethnographic approach. The data were collected through observation, interviews, and documentation. Based on the results, it can be explained that in the process of weaving silk, the craftsmen combine the techniques of counting, designing, placing, and measuring as mathematical activity to produce various motifs. The weaver's ability to count and design motifs produces geometric planes that are transformed through a combination of reflection, translation, and dilatation. In making visualized motifs resembling curved planes such as the lagosi motif, the phinisi or the batumesang motif, they are approximated by using a collection of rectangular pixels from the arrangement of warp, weft and other motif yarns such as gold or viscose. The redesign of the silk motif uses the the number patterns identified on the arrangement of the yarns. In algebra, the lipa’ sabbe motif can be represented by a set of constant functions, parallel linear functions, or degree-n polynomial. The results of this study indicate that the mathematical concepts in lipa’ sabbe motifs are not only in the form of geometric concepts, but also include the concepts of number pattern, and algebra. Based on the manufacturing process and the resulting motifs indicate that the craftsmen have uniq mathematical abilities.

Abstract

Several studies tried to introduce some of the efficient factors that can influence fostering mathematical creativity in learning environments. since some of the variables associated with mathematical creativity in educational environments depend on the culture, conducting research in this area seems necessary. It should be noted that the contribution of Iranian researchers to these studies is very small. The paper aims to study the role of instructors in nurturing creativity in mathematics students from math students’ point of view and to present a conceptual model. The research is a qualitative study conducted using grounded theory. Participants were selected from university students who are studying mathematics in the universities of the city of Tehran in Iran using purposive sampling and the sampling is stopped until theoretical saturation. Finally, semi-structured in-depth interviews were conducted with 10 students. Interviews were audiotaped, transcribed, and coded in the two stages of free coding and axial coding. Classification of codes led to numerous categories. The findings show that instructors can influence several aspects: belief, intention, mathematical knowledge, mathematical thinking, and personality characteristics such that being persistent, being a risk taker, and forgetting fixation.

Abstract

Although problem solving has been playing a critical role in the teaching and learning of mathematics in K-12 in many countries in the world, anecdotal evidence from mathematics classrooms shows that teachers are still facing challenges in designing mathematical tasks on problem solving for classroom instruction. Despite the effort of several existing research studies on enacting problem solving in the mathematics classroom, the guiding principles for designing problem solving tasks remain largely unexplored, thus teachers are left without being empowered to design their own problem solving tasks. The objective of this paper is to provide a comprehensive framework on designing problem solving tasks through a list of interrelated guiding principles. The proposed framework, which we name MIRACLE, foreground seven key considerations which mathematics educators should take into consideration when designing a task for a problem solving lesson: Mathematical content, method of Instruction, Required knowledge, Assessment, Complexity of problem, Learner’s profile, and Enactment of lesson. This paper also provides two exemplars on how the framework could be used to design mathematical tasks for problem solving through problem solving
