Relational reasoning plays an important role in helping students to understand mathematical concepts. The student's ability to distinguish patterns or objects is one of the understandings of mathematical concept indicators. The anomaly dimension is part of the relational reasoning that students need to be able to determine a pattern or object in mathematics. This study aims to reveal the student's relational reasoning ability of anomaly dimension in solving number pattern problems in terms of gender differences. The subjects of this study are 52 grade-8 students in one of Muhammadiyah Junior High Schools in Kartasura. We used two similar problems on number patterns to disclose the student's ability to identify the pattern deviation in solving problems. The two selected students had relatively similar in their mathematical abilities. The finding showed that female subject met the three anomaly dimension indicators: identification, interpretation, and adaptation. Conversely, male student cannot fulfill the anomaly indicators. He cannot recognize pattern deviation in the formed mathematical model. He also failed to identify a pattern different from the two problems. Although the subjects interviewed were limited, the finding provided the insightful into the differences in anomaly reasoning abilities in male and female students

This research aims to analyze the productive pedagogies of the pre-service teachers. Productive pedagogies are measured based on four dimension. This research involved three pre-service teachers in Universitas Negeri Makassar, Indonesia, who carry out teaching practices in schools. This research is a case study. The assessment of productive pedagogies was measured using a questionnaire, observation, and semi-structured interviews. The lowest average was found on the intellectual quality dimension of 79.6 (high category) based on the overall dimensions. This result suggests that, of all of the dimensions, Intellectual Quality was the least likely to be included in the classes. The highest dimension of the productive pedagogies of the pre-service teacher was connectedness, around 84.7, with a very high category. That means the pre-service teachers mainly focused on Connectedness during their teaching practice, followed by the Recognition of Differences around 82.2 (high category). Meanwhile, the Supportive Classroom Environment dimension is in the high category at about 79.9. Furthermore, for the Supportive Learning Environment dimension, two elements, academic engagement and self-regulation, were frequently observed in all pre-service teachers' classes. Still, student control, in which the teacher gives students chances to determine specific activities or outcomes of the lesson, was not very often.

Individuals with low immune systems have a higher impact on the Covid-19 outbreak. Herbal treatment is one of the solutions to reduce the risk of being infected by the virus. However, the public has not yet fully known about herbal medicines in Indonesia. One of the efforts to increase students' knowledge about herbal medicine is by developing numeracy questions in the context of herbal medicine. This study aims to produce valid and reliable numeracy questions in the context of herbal medicine for junior high school students and to find student responses to numeracy questions in the context of herbal medicine. The research method used is a design research type of development study with a Tessmer development model. The results of the study were 16 numeric questions with the context of herbal medicines that were valid in terms of content, construct, and language based on the validator's assessment, while nine of the 16 questions met empirical validity. The numeration question set in the context of herbal medicine has a high-reliability value. Based on the students' responses, the set of questions developed positively impacted students. The teacher can use these questions as an instrument to train students' numeracy ability.

The Effect of Interactive Multimedia-Based Learning on Students’ Mathematical Critical Thinking Ability in the Course of Structure Algebra Lilis Marina Angraini; Nurmaliza Nurmaliza
Didaktik Matematika Vol 9, No 2 (2022): OCTOBER 2022
Publisher : Universitas Syiah Kuala

The critical thinking ability is fundamental in learning mathematics so it must be possessed by students as prospective teachers. In fact, the students' mathematical critical thinking ability is still relatively low. In this case, one of the causes is the change in learning system from face-to-face to online learning. One effort that can be done to overcome this issue is to apply interactive multimedia-based learning. Current research was further conducted in this matter, aiming to improve students' mathematical critical thinking ability through interactive multimedia-based learning to support online learning. This quantitative research (quasi-experimental) was carried out by involving prospective mathematics teacher students enrolling in the algebraic structure course in 2021/2022 at Universitas Islam Riau (UIR) as the experimental class and prospective mathematics teacher students at Universitas Pasir Pengaraian (UPP) as the control class. The data were further collected through a mathematical critical thinking ability test which were further analyzed through statistical tests. Based on the results of the t-test, there was an increase in students' mathematical critical thinking ability who received a learning process using interactive multimedia.

Publisher : Universitas Syiah Kuala

This research was motivated by the low achievement of Indonesian students in the assessment of PISA problems and the Islamic context that is familiar to students. The purpose of this research was to produce valid and practical PISA-like mathematics problems using Islamic context in junior high school and to find out the potential effect of the problem on mathematical literacy ability. The subjects of this study were students of the Ninth grade in one of Junior High School, in South Sumatera, Indonesia. Furthermore, the methodology used was design research with the type of development study. The validity was obtained based on the assessment of the validator (expert) regarding the content, construct, and language used and student work in the one-to-one phase. Meanwhile, the practicality can be seen from the work of students in the small group phase where students can understand the meaning or language of the questions. Furthermore, the potential effect can be seen from the strategy of students in working on the questions during the field test. In this case, the potential effects that arise were mathematical communication ability, mathematical representation ability, and ability of devising strategies for solving problems, as well as mathematization ability.

Mathematical Literacy with Islamic Nuances Based on Prospective Mathematics Teachers’ Personality Eka Resti Wulan; Fidia Astuti
Didaktik Matematika Vol 9, No 2 (2022): OCTOBER 2022
Publisher : Universitas Syiah Kuala

Mathematical literacy is crucial to understand phenomena and good decision-making in real life. This study aims to describe aspects of Islamic nuanced mathematical literacy in prospective teachers, which were viewed from the four personalities of Keirsey. This qualitative descriptive research used a questionnaire of MTBI personality types and a mathematical literacy test with Islamic nuances. The subjects are students in the 7th semester of the mathematics education program at an Islamic university in Kediri City, East Java, Indonesia. The findings showed that rational and idealist subjects could fulfill the "formulating" indicator, but not the guardian and artisan subjects. They were not able to translate problems into mathematical form. The indicators of "employing" and "interpreting" show that subjects with rational personality types can determine better strategies than artisan, guardian, and idealist personality types. That is, it is necessary to integrate the interconnections between the mathematics learning programs related to Islamic elements. A more in-depth portrait of mathematical literacy is needed in different situations from prospective mathematics teachers at Islamic universities.

Technology has become a crucial part of the learning process and a facilitator of the interaction between students and teachers. Spatial ability is a crucial ability in mathematics learning and success in STEM. In this case, Augmented Reality (AR) in mathematics learning can facilitate the abstraction of mathematics that represents a new representation of mathematics concept. The objectives of this study were to develop an application using AR which was further used to improve the spatial ability of Junior High School students. Meanwhile, the method used in this study was RD using the ADDIE model and quantitative approach through t-test. In this case, 64 students of 8th grade in Junior High School were involved as the research samples, where 32 students were in the control class and 32 students were in the experimental class. The results of this study were that the AR application was feasible to use in mathematics learning and its application enabled teacher and students to learn solid geometry using Augmented Reality with the object that can be manipulated, interact in real-time, and measure objects in the real world. It was also obtained that the learning outcomes of students who used the application were higher than the learning outcomes of students who did not use application, indicating that the application could increase stdudents spatial ability.
