Abstract

Mathematical competence refers to the skills of students in reasoning, connection, communication, representation, and problem-solving. Various researchers have massively discussed on how to foster mathematical competence. However, it is just a few of them comprehensively explain from the cognitive styles perspective. This research aims to measure the junior high school students’ mathematical competence based on their cognitive style.This research used a descriptive qualitative approach. There were 35 students took part in the mapping of cognitive styles using the Matching Familiar Figure Test and were then selected representative from the reflective and the impulsive cognitive style to have a further assessment of the mathematical competence using the mathematical competence test. The data analysis usedthe model of Milles and Huberman. The results showed that there was a difference mathematical competence between the subject having impulsive cognitive style and the one having reflective cognitive style. The percentage of mathematical competence of reflective subject was 69% while the impulsive subject was 56.89%. From all aspects of mathematical competence, the reflective subject tends better ability; for instance, the reflective subject has better ability than the impulsive subject on mathematical connection, mathematical reasoning, mathematical representation, and problem-solving.

Abstract

Target yang ingin dicapai dalam penelitian ini adalah mendeskripsikan sejauh mana pendekatan SRFC mampu membuat mahasiswa program studi pendidikan matematika Universitas Ahmad Dahlan (UAD) belajar mandiri. Paradigma baru yang berkembang di perguruan tinggi menuntut pembelajaran harus mampu memandirikan mahasiswa dalam belajar (self regulated learning). Pendekatan pembelajaran yang secara teori berpotensi mampu memfasilitasi belajar mandiri adalah pendekatan SRFC. Penelitian ini menggunakan pendekatan deskriptif kualitatif. Bedasarkan hasil penelitian, penulis berharap pendekatan Self Regulated Flipped Classroom (SRFC) tidak hanya diterapkan pada mata kuliah Kalkulus diferensial saja melainkan dapat menjadi rujukan pada mata kuliah lain. Adapun pelaksanaan SRFC dari sisi kognitif masih memiliki kekurangan dimana mahasiswa belum terlibat aktif dalam melakukan refleksi berpikir selama pembelajaran, namun mahasiswa lebih terlibat aktif dalam sisi intepretasi. Selain itu, motivasi dan perilaku mahasiswa cenderung positif selama menggunakan pendekatan pembelajaran SRFC. Hal ini dikarenakan adanya dukungan dari pengajar dan teman sejawat serta interaksi selama pembelajaran berlangsung. Kata kunci: kalkulus, SRFC, kemandirian belajar.   ABSTRACT This research aims to describe the SRFC approach through self regulated indicators and the result of the study of college students in Universitas Ahmad Dahlan. The new paradigm related to Higher Level Education strive for students whom can independently get their own knowledge. SRFC has a potential method to make the students study independently. This research is using qualitative descriptive approach. Based on the result, the author recommend to used SRFC approach not only implemented in Calculus Diferential course but also the other subject. As far as the SRFC activities, cognitive domain hasn’t actively contributed in teaching and learning process because the students havent involve their reflection in learning the subject. However, their intepretation of the subject is actively involved better. In addition, the motivation and the attitude of the students is positive in using SRFC approach. It is because there are support from the teacher and their collegaues and their interaction while they were studying. Keywords: calculus, self-regulated learning, mastery learning.

Abstract

Masyarakat Dusun Plurugan dan Dusun Dongkelan Bantul memiliki sumber daya manusia yang baik, namun belum optimal. Kaum muda belum bersinergi dengan baik sehingga belum mampu diberdayakan untuk menjaga kondusifitas jam belajar di lingkungan kampong, salah satunya dalam belajar dan mengaji. Hal ini ditunjukkan pula dengan kurang berkembangnya prestasi anak-anak baik dalam bidang keagamaan maupun akademik. Oleh karena itu, KKN Alternatif 61 Universitas Ahmad Dahlan berusaha membantu agar taman pendidikan Al Qur’an dapat dilakukan secara merata kedua dusun tersebut dan mencanangkan program jam belajar masyarakat. Dampak dari kegiatan KKN ini adalah: (1) terciptanya kesadaran masyarakat akan pentingnya belajar ilmu agama maupun ilmu umum; (2) peningkatan pengetahuan anak-anak dalam belajar membaca Al-Qur’an, dan (3) meningkatnya antusiasme anak-anak dalam kegiatan taman pendidikan Al Qur’an.

Abstract

Meeting students' needs based on their characteristics is crucial to ensure they can learn comfortably and optimally. The objective of this research is to formulate learning plans that align with students' characteristics. This study adopts a descriptive qualitative approach, encompassing case studies and literature reviews. The research was conducted at Public Senior High School of Godean 1, with the subjects being 36 students from the 11th Science 3 class. Observation sheets and questionnaires were employed as instruments to identify students' characteristics, guided by the theory of differentiated learning. The analysis techniques involved data reduction, data presentation, and drawing conclusions/verification. Observation results indicate that the learning process has not effectively addressed students' Zone of Proximal Development (ZPD) and learning modalities. The majority of students operate at the potential level, with visual, kinesthetic, and audio modalities being the dominant ones in that order. A literature review on learning design suggests that differentiated learning, particularly through methods such as discovery learning and gallery walks, can serve as alternatives to meet these diverse learning needs.

Abstract

Mathematics literacy is individual capacity to formulate, to employ, and to interpret mathematics in various contexts. Indonesian students aged 15 are required to perform these three skills and these abilities reflect the success of the curriculum. The results, however, are never considered satisfying since, many argue, the students are not accustomed to deal with the mathematics literacy problems. Teacher is then the one who takes the responsibility to make the students familiar with the literacy problems. This research aims to look closer at the mathematics literacy skills possessed by pre-service teachers. It is a qualitative research which involved 128 undergraduate student teachers as the subjects. A custom mathematics literacy test was developed with various contexts to measure the student teachers’ literacy skills according to the PISA framework. The results suggest that they performed well in the level 1 to 3 problems, but not in the level 4 to 6. Many errors made by the student teachers in the stage of formulating, employing, or interpreting. Finally, teachers need to be accustomed to this skill before they are ready enough to teach their students.

Abstract

STEAM learning is an approach which integrates multidisciplinary knowledge while enriching students' skills to explore, try, ask, find, and build innovation, namely science, technology, engineering, art, and mathematics. We found that the learning resources of STEAM in Yogyakarta is very limited due to lack of knowledge about it. On the other hand, using local contexts as the starting point of learning is also important to foster character building. This preliminary research aims to provide insight on the teachers’ awareness on STEAM learning and textbook, as well as the design we figured out after discussing it with the teachers. It was a descriptive qualitative research involving 214 primary school teachers. We collected the data through questionnaire and focus group discussion. The results suggest that STEAM is quite a new concept for most of primary school teachers in Yogyakarta. Not many teachers used to or have developed the STEAM learning resources, especially the one integrated with the character building. Therefore, a STEAM textbook needs to be developed to fulfill the need. Furthermore, the design of the textbook could have the characteristics of integrating all components of STEAM (science, technology, engineering, art, mathematics), starting from local context to develop characters, improving creative and critical thinking, having knowledge and skill assessment, and using project-based learning model.

Abstract

Heuristic strategy is one of the mathematics problem solving strategies to gain effective results. This research aimed to analyze the use of the heuristic strategies based on the modification of the Krulik and Rudnik model. This research discovered and classified the students' heuristic strategies which can be used as a basis to provide assistance in the learning. This research was a qualitative research involving 32 students of SMP Muhammadiyah 4 Yogyakarta as its subjects. The research variables are the indicators of the Krulik and Rudnik heuristic models which the students performed including: read and think, explore and plan, select a strategy, find and answer, as well as reflect and extend. The data was taken through questionnaire and interview methods. The result suggested that: 2 students (6.25%) were in the good category as they did all of the heuristic strategies more often; 21 students (65.62%) were in the fair category since they implemented some indicators of the heuristic strategies; and 9 students (28.13%) were in the poor category since they were lack in implementing the heuristic strategies. In all categories, indicator of find and answer was more oftenly done by the students while the indicator of explore and plan was less done.

Abstract

This article aims to investigate how mathematics education students in Universitas Ahmad Dahlan solve PISA mathematics problems. This research used the descriptive method with the qualitative approach and supported with quantitative data. Research subjects were 20 new students of mathematics education at Universitas Ahmad Dahlan in the 2016/2017 academic year. We translated the 2012 PISA instrument and used it to collect data on students’ mathematical literacy skills and to identify their difficulties. All the data were analyzed based on PISA’s framework. The result shows that, in general, 65.7% of students were able to understand the problems and plan their strategies to solve them. Meanwhile, only 46.9% among them could answer correctly. In addition, only 36.8% of the students were able to understand the level 6 problems while only 23.7% among them answered correctly. The students performed well in the interpretation process towards the problems with individual and social contexts. However, they found difficulties in the formulation and employment process of the problems, especially in the work and scientific context.
