This study aims to develop student worksheets with a guided inquiry approach that meet valid and practical criteria. The type of research is research and development (RD). The development model used is a 4D model consisting of define, design, development, and disseminate stages. This study involved material validators, media validators, and 7th grade students of Al Azhar 26 Islamic Junior High School Yogyakarta. The research data was obtained from the results of the assessment using a validation sheet and student response questionnaires. The average score of the assessment results from the material validators is 74 with very good validity level criteria, from media validators 127.5 with very good validity level criteria, and from the large group practicality test an average of 88 with very good practicality criteria. Student worksheets are declared valid and practical based on the stages of development and established criteria, and can then be used to explore students' critical thinking skills.

This study aims to examine mathematics teacher-candidate students’ mathematical creative reasoning ability based on the level of Adversity Quotient (AQ). This study uses a mixed method of sequential type by combining quantitative and qualitative methods in order. Population in this study is all students attending the course of Calculus in Mathematics Education of Master Program at STKIP Siliwangi that consist of 270 students divided into six classes. The results are AQ gives effect to the achievement of students’ mathematical creative reasoning abilities based on the whole and the type of AQ climber, champer, and quitter. The achievement of students’ mathematical creative reasoning abilities and based on AQ, the champer and climber fall into the medium category, while on the quitter type, it falls into the category of low. On the other hands, the achievement of students’ mathematical creative reasoning abilities is yet to be achieved well at the indicator of novelty.

Learning Trajectory of Dilation and Reflection in Transformation Geometry through the Motifs of Bamboo Woven Maryati Maryati; Rully Charitas Indra Prahmana
Didaktik Matematika Vol 8, No 2 (2021): Jurnal Didaktik Matematika
Publisher : Universitas Syiah Kuala

Cultural diversity around students can be integrated into learning mathematics in the classroom. Yet, Indonesian students still have difficulty applying mathematical concepts to solve problems related to everyday life, such as dilation and reflection in transformation geometry. Therefore, this study aims to design the dilation and reflection in transformation geometry learning trajectory using the motifs of bamboo woven. This context was used as the starting point in the learning process by applying the Pendidikan Matematika Realistik Indonesia approach. The research method used is design research consisted of three stages: preliminary design, teaching experiment, and retrospective analysis. This study describes how the motifs of bamboo woven made a real contribution for ninth-grade students to understand the concept of dilation and reflection in transformation geometry. The design experiments showed that this context can stimulate students to understand their knowledge of the idea of dilation and reflection in transformation geometry. All of the strategies and models that students find illustrate and discuss show how the construction or contribution of students can be used to help their initial understanding of the reflection and dilation.

Sejumlah penelitian terkait implementasi pembelajaran matematika pada anak berkebutuhan khusus (ABK) telah banyak dilakukan di Indonesia dan terpublikasi dalam jurnal-jurnal nasional terakreditasi. Namun, belum ada survei artikel mengenai penelitian-penelitian implementasi pembelajaran matematika pada ABK di Indonesia. Sehingga, tujuan dari penelitian ini adalah untuk mengklasifikasikan seluruh penelitian tersebut ke dalam beberapa kategori yang berhubungan dengan penelitian implementasi pembelajaran matematika pada ABK di Indonesia. Penelitian ini menggunakan metode Systematic Literature Review (SLR) yang digunakan untuk mengindentifikasi, mengkaji, mengevaluasi, dan menafsirkan penelitian-penelitian pada topik implementasi pembelajaran matematika pada ABK di Indonesia. Data yang digunakan berasal dari 17 artikel yang terdapat dalam 13 jurnal pendidikan matematika yang telah terakreditasi oleh Kementrian Riset, Teknologi, dan Pendidikan Tinggi Republik Indonesia pada kategori Sinta 1 dan 2. Hasil penelitian ini mengelompokkan seluruh artikel yang di analisis ke dalam lima kategori, yaitu subjek, jenjang pendidikan, materi, kemampuan siswa, dan metode yang digunakan dalam penelitian-penelitian tersebut. Hasil ini berkontribusi dalam memberikan informasi yang komprehensif terkait tren penelitian implementasi pembelajaran matematika pada ABK di Indonesia, sehingga nantinya dapat menjadi rekomendasi dan ide awal dalam penelitian implementasi pembelajaran matematika bagi ABK selanjutnya. AbstractSeveral studies related to implementing mathematics learning in Children with Special Needs have been widely carried out in Indonesia and published in accredited national journals. However, there has been no article survey on research on mathematics learning for children with special needs in Indonesia. Thus, the purpose of this study is to classify all of these studies into several categories related to research on the implementation of mathematics learning in children with special needs in Indonesia. This study uses the Systematic Literature Review (SLR) method, which is used to identify, review, evaluate, and interpret research on implementing mathematics learning for children with special needs in Indonesia. The data used comes from seventeen articles contained in thirteen mathematics education journals that have been accredited by the Ministry of Research, Technology and Higher Education of the Republic of Indonesia in the Sinta 1 and 2 categories. The results of this study grouped all analyzed articles into five categories, such as subject, level of education, topic, student abilities, and research methods used in these studies. It also contributes comprehensive information about research trends in implementing mathematics learning for children with special needs in Indonesia. Later, they can become recommendations and initial ideas in research on implementing mathematics teaching and learning for children with special needs.
