Abstract

Developing entrepreneurial characters and skill is one of the goals of Faculty of Teacher Training and Education Pancasakti University Tegal. To achieve this goal, the learning process needs to support the development of entrepreneurial characters, such as self-confidence, hard work and unyielding, cooperative, independent, and active and creative. Learning activities should be able to provide opportunities for students to participate actively. Therefore, this study aimed at designing a Maple-integrated workbook to help students establish their entrepreneurial character. The workbook helps students build the character of independent in learning calculus, active and cooperative in solving problems, and creative in using Maple to explore the concept of calculus. This study employed Research and Development by adapting Borg and Gall's steps, which are preliminary information, design, preliminary development, validation and preliminary revision, field test and final revision. The entrepreneurial characters instrument is a questionnaire comprising statements that reflect the characters of entrepreneurship, which are self-confident, hard work, cooperative, independent, and active and creative. The result of questionnaire analysis showed that in general students’ entrepreneurial characters are in a good category, with the average score of entrepreneurial character is 2.85 out of 4.

Abstract

A factor that contributes to students’ low performance in Calculus is that some teachers and lecturers tend to explain the concept of integral by using a set of symbols, notations, and rules without providing any contexts or representations of the concept. This study was aimed at supporting college students’ understanding of integral by integrating Maple in the learning process using Maple-integrated workbook. This study adapted Brog and Galls’ procedures which consist of collecting preliminary information, planning, developing, validation and preliminary revision, field test, and final revision. The subject of this study was college students’ of Mathematics Education Department of UPS Tegal. The result showed that module developed was in a good criteria, and the conceptual understanding test showed that 82,4% students in the experimental class got a score of 71 or higher. Moreover, the average score of the experiment and control class also confirmed that the average of students’ score in experiment class was significantly higher than that of students in control class.

Abstract

Percentage is found to be a familiar and challenging topic at the same time. Percentage has many application in daily life, yet many students still find it difficult. It might because many schools teach merely a formal procedure and pay less attention to the understanding of the reasoning behinds percentage ideas. This small study employed a design research and aimed at supporting students in understanding percentage by using bar model. Eleven 6th and 7th grade students of American International School of Rotterdam were participated in this study. A sequence of learning activities was designed to help students construct their understanding of percentage. The activities consisted of some rich contextual problems that lead to the emergence of bar model. The result revealed that the model can help students construct students’ knowledge of the relation among numbers in percentage, and also help them solve percentage problems systematically through some intermediate steps which include benchmarks.

Abstract

Proses perkuliahan di program studi Pendidikan matematika belum mengintegrasikan komponen e-learning. Penggunaan teknologi dalam perkuliahan pun masih jarang. Dengan pengintegrasian LMS Moodle dalam perkuliahan tatap muka, akan menunjang terbentuknya blended learning. Adanya implementasi Blended learning pada mata kuliah Geometri transformasi diharapkan  keaktifan mahasiswa semakin meningkat..Penelitian pengembangan pada penelitian ini merujuk pada model pengembangan ADDIE (Analyze, Design, Develop, Implement, Evaluation). Penelitian ini pada tahap Implement (Implementasi), yaitu menguji cobakan produk di lapangan untuk mengetahui pencapaian tujuan pengembangan produk.Implementasi Blended learning pada mata kuliah Geometri transformasi diharapkan  keaktifan mahasiswa semakin meningkat. Hal ini dapat terlihat pada presentase mahasiswa yang berpartisipasi pada kelas LMS moodle nya atau dalam blended learning; grader report serta perbedaan nilai geometri transformasi. Diharapkan dalam mengimplementasi Blended learning akses jaringan internet yang tersedia harus memadai sehingga tidak menghambat proses login ke sistem LMS Moodle.

Abstract

Buku teks dapat mempengaruhi proses belajar peserta didik. Setiap kurikulum yang berlaku memiliki buku teks sebagai bahan ajar utama. Beberapa sekolah SPK di Indonesia mengadaptasi kurikulum yang diterapkan di Singapura. Penelitian ini bertujuan untuk mengetahui perbandingan konten materi dan penyajian materi pada buku teks matematika Indonesia dan Singapura pada materi SPLDV. Penelitian ini menggunakan pendekatan kualitatif dengan jenis penelitian deskriptif komparatif. Perbandingan ini menggunakan buku teks matematika kurikulum 2013 kelas VIII Semester 1 dan buku teks Discovering Mathematics 2A (2nd Edition). Berdasarkan hasil analisis, kedua buku teks tersebut memiliki persamaan dan perbedaan masing-masing dalam setiap aspek dan komponen yang dianalisis. Pada cara penyajian materi, buku teks matematika Indonesia cenderung monoton dalam satu halaman secara padat diisikan oleh tulisan namun dalam pemilihan warna bervariasi. Sedangkan dalam buku teks Singapura, cara penyajian materi memanfaatkan tata letak yang bervariasi dengan menambahkan spot kecil (bubble) walaupun dalam pemilihan warna tidak terlalu bervariasi. Kelebihan buku teks Indonesia yaitu pemanfaatan masalah kontekstual saat memperkenalkan sebuah konsep, sedangkan pada buku teks Singapura masalah kontekstual hanya disajikan dalam latihan soal. Di sisi lain, buku teks Singapura memiliki kelebihan dalam hal integrasi pemanfaatan teknologi dan antisipasi miskonsepsi peserta didik.

Abstract

Integrating cultural context into teaching and learning activities can help students understand the material. However, the development of teaching materials that integrate local cultural contexts is still not widely practiced. This study aims to (1) describe the results of exploring the architecture of the Grand Mosque of Sang Cipta Rasa Cirebon as a teaching material for mathematics, (2) determine students' responses to the mathematics teaching material resulting from the exploration of the architecture of the Grand Mosque of Sang Cipta Rasa Cirebon, and (3) determine the difference in mathematics learning outcomes before and after using the mathematics module. This study applied the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation). In the architecture of the Grand Mosque of Sang Cipta Rasa, concepts of two-dimensional shapes such as triangles and quadrilaterals were found, including squares, rectangles, trapezoids, and rhombuses. The expert validation results show that the developed mathematics module is highly feasible to implement, with percentages of content, presentation, and language feasibility aspects reaching 88%, 90%, and 89% respectively. Students' responses to the mathematics module were categorized as good (71%). Paired sample t-test results show that students' learning outcomes before and after using the developed mathematics module are significantly different, with higher learning outcomes after using the mathematics module compared to before its use. Thus, the mathematics module resulting from the exploration of the architecture of the Grand Mosque of Sang Cipta Rasa Cirebon can be implemented in learning to improve mathematics learning outcomes.
