International Journal on Emerging Mathematics Education IJEME, Vol. 3 No. 2, September 2019
Publisher : Universitas Ahmad Dahlan

Professional teachers need to be skilled in planning their lesson. One of the activities to plan the lesson is analyzing the competence and teaching material demanded by the curriculum. This article aims to describe the Indonesian pre-service mathematics teachersâ€™ skills in analyzing junior high school mathematics competence. The analysis is important to prepare the appropriate material for their students. This is qualitative research involving 26 pre-service teachers enrolled in the subject of Curriculum Analysis for Junior High School. First, they were assigned to analyze a given basic competence and were then challenged to select the appropriate materials and the indicators when the competence achieved according to Bloom taxonomy. Surprisingly, though there are many reference books available for sources of analysis, the teacher candidates found some difficulties in arranging the topics and composing the appropriate indicators. Some errors found such as the use of unmeasurable verbs, unclear activities, and illogical-irrelevant topics.

The effective use of manipulatives still become a debate among the mathematics educatos. This research aims to describe the perception of pre-service teacher towards the use of manipulatives in mathematics teaching practice. This research is a qualitative research which focused on the students’ responses of mathematics education department towards the aspect of effectiveness of manipulatives, the aspect of students, the aspect of material, and the aspect of learning strategy through the administration of questionnaire and interview. The research subjects were also involved in developing the manipulative project and used them in a peer teaching session. The result suggested that 83.3% of respondents believed that manipulatives could effectively help students to understand the mathematics concept. There were 50% respondents believed that all students, regardless their level of understanding ability, need a manipulatives-aided learning. However, it was only 20,8% who thought that all mathematics material can be taught using manipulatives and 62,5% thought that teacher needs a special strategy to implement the manipulatives in their learning. The perception reflects that it is still important to develop manipulatives in mathematics learning.

We might need a little anxiety: A finding of the students' problem-solving on fraction operation Yuli Purwasih; Vita Istihapsari; Afit Istiandaru
International Journal on Education Insight Vol. 1 No. 1 (2020)
Publisher : Universitas Ahmad Dahlan

One of the factors affecting the students' mathematical problem-solving ability is the mathematics anxiety. It was commonly believed that the higher anxiety a student feels, the lower performance the student does. This research aims to describe the students' problem-solving performance on fraction operation within three levels of mathematics anxiety - the high, the moderate, and the low anxiety. In this research, we selected six subjects by administering a questionnaire. The subjects - representing each of the anxiety levels - engaged in a problem-solving test on fraction operation and then being interviewed about their problem-solving process based on Polya framework. After a number of triangulations and discussions, we found that the students with high anxiety tended to ruin their problem-solving process due to somatic symptoms. We also found that the students with moderate anxiety developed a good care such that the process going well. Interestingly, the students with low anxiety did not carefully solve the problems and made some mistakes in calculation. A simple question might be addressed for future research. Does anxiety sometimes develop a good alert that makes the student careful about their problem-solving steps?

Kemampuan berpikir kreatif penting dimiliki siswa dalam proses pembelajaran matematika Namun, faktanya siswa masih mengalami kesulitan dalam membuat kebaruan saat diberikan sebuah permasalahan. Tujuan dari penelitian ini adalah untuk menganalisis kemampuan berpikir kreatif siswa ditinjau dari kemandirian belajar tinggi, sedang dan rendah pada pembelajaran matematika. Penelitian ini merupakan penelitian kualitatif deskriptif. Subjek dari penelitian ini terdiri dari 6 siswa kelas VII di sebuah SMP yang berlokasi di Kecamatan Muntok Kabupaten Bangka Barat yang memiliki kemandirian belajar tinggi, sedang, dan rendah. Data dikumpulkan menggunakan angket, tes, dan wawancara. Keabsahan data diperiksa menggunakan triangulasi metode. Selanjutnya, data dianalisis secara kualitatif melalui reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian ini menunjukkan bahwa subjek dengan kemandirian belajar tinggi mampu memenuhi indikator berpikir kreatif aspek kefasihan, fleksibilitas, dan kebaruan sehingga tergolong sangat kreatif. Subjek dengan kemandiriran belajar sedang memenuhi indikator berpikir kreatif aspek kefasihan dan fleksibilitas sehingga kreatif. Sedangkan subjek dengan kemandirian belajar rendah hanya memenuhi indikator berpikir kreatif aspek kefasihan sehingga tergolong kurang kreatif.

Javanese context is rich of phenomena potentially used as a starting point to learn mathematics. On the other hand, the Indonesian students’ performance in PISA is consistently low due to the small number of PISA-like problems which can be used to foster the students’ mathematical literacy measured in PISA. Therefore, this research aims to develop a set of PISA-like problems using the Javanese context targeted for 8th-grade students of Junior High School. It is a development study using Plomp’s framework in the stage of need analysis and prototyping. We have successfully developed a prototype of PISA-like mathematics problems using Javanese context. There are six items covering seven basic competences in the 8th-grade of junior high school. The items used various mathematics skills such as communication, representation, mathematization, devising strategies, and reasoning. We could explore some Javanese contexts such as traditional building, transportation, calendar system, community meeting, and historical place. Meanwhile the school mathematics materials include number sequence, Cartesian coordinate, relation, linear function, linear equation system in two variables, and Pythagorean theorem.

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.
