Abstract

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.

Abstract

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.

Abstract

Students' thinking styles are important factors for teachers to accommodate all types of students' thinking styles in a learning approach. Therefore, this study aims to determine students' mathematical problem-solving skills from their respective thinking styles using a metacognitive approach. The sample in this study was 60 students of class XII Madrasah Aliyah Negeri Ambon consisting of 31 Mathematics IPA-1 classes as the experimental class and 29 Mathematics IPA-2 classes as the control class. This research is a quasi-experimental study with a pretest-posttest control group design. The research instruments used were tests (pre-test and post-test) and the thinking style instrument. The data were tested by univariate test and t-test. The experimental class concluded; There are differences in the improvement of students' mathematical problem-solving abilities between groups of thinking styles and there is an influence of thinking styles on problem-solving abilities. While in the control class; There is no difference in increasing students' mathematical problem-solving skills between groups of thinking styles, nor is there any influence of thinking styles on problem-solving abilities. These results illustrate that students' mathematical problem-solving skills can be influenced by thinking styles as a result of the learning approach used, namely the metacognitive approach.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

This study aims to develop a learning media in the form of a dynamic number card game based on number sense as a media for learning mathematics for first graders. This study uses the research and development (RD) with ADDIE model. Data collection techniques were interviews, observation, and questionnaires. The quality of the dynamic number card game was obtained from the validity and practicality test. Expert validation was carried out to evaluate the quality of media and content. The practicality test was conducted one-to-one (3 students) and in small groups (6 students working in small groups). The results showed that the dynamic number card game received a high score of validity from the expert judgment. The students also had positive responses to the practicality of the dynamic number card game in guessing and ordering numbers. The findings indicate that the dynamic number card game has the potential to be used as a medium for learning number sense for first grade students.

Abstract

Students' mathematical abilities are still considered low due to the lack of students' mathematical connection abilities. One effort that can be done in overcoming the low ability of students' mathematical connections is to involve the culture around students in the learning process. This study aims to analyze students' mathematical connection ability through the application of learning strategies based on local wisdom a'bulo sibatang, assamaturu, mappesabbi and sipakatau. The research method used is a quantitative quasi-experimental type of nonequivalent control group design. Through purposive sampling technique, it was obtained class XI MIPA 3 (experimental class) and XI MIPA 1 (control class). The instrument used is a test to indicators of mathematical connection ability. The results showed an increase in indicator of mathematical connection ability in the experimental class, namely 88.52% indicator I, 85.35% indicator II and 83.87% indicator III. Meanwhile, in the control class applied problem-based learning strategies only got a score of 65%. Based on the results of the analysis, it can be concluded that local wisdom-based learning in the experimental class is able to improve students' mathematical connection ability better than the control class that applies problem-based learning.

Abstract

Mathematical representation ability (MRA) is crucial in solving mathematical problems, particularly in the topic of algebraic expressions. However, some students struggle to grasp algebraic forms in real-world circumstances. Learning through realistic mathematics education (RME) using context is one of the learning approaches that could help improve students' MRA. The objective of this study was to assess students' MRA in learningalgebraic expressionsthrough realistic mathematics education. This research employed mixed-method research with a sequential explanatory design. The subjects of this study were 27 seventh-grade students from a junior high school in Banda Aceh, Indonesia. Data on students' MRA were gathered through written test and task-based interviews. The descriptive analysis of written test data revealed that students' average score is 3.6, which is considered low compared to the maximum score of 8. The majority of students (n=24) satisfied the visual indicators of MRA as they successfully drew the composite shape. Whereas the most challenging MRA aspect for students to master was symbolic representation, only a few students (n=6) could solve the problem related to the multiplication of algebraic expressions. Students learning loss in the prerequisites due to online learning during the Covid-19 outbreak was one cause of the students' low performance on MRA.
