Abstract

Objective: This research aims to: 1) develop a worksheet that incorporates unplugged computational thinking (CT) to support the strengthening of mathematical literacy; 2) test the validity, practicality, and effectiveness of the worksheet. Method: This study employed a development research design involving teachers, students, and experts. Data collection was conducted through literature review, observation, questionnaires, documentation, and a mathematical literacy test. Data analysis was conducted using qualitative and quantitative methods. Results: Based on the research results, the following results were obtained: 1) The CT-infused worksheet was designed to support the achievement of three learning objectives: students can determine sample points, determine probability values, and use these concepts in problem-solving; the worksheet contains learning activities that integrate CT and learning activities that support mathematical literacy; 2) The content validity index was 1, thus the worksheet is valid; Practicality tests by teachers and students yielded scores of 3.95 and 3.58, respectively, indicating that the worksheet is suitable for use as a support for mathematics learning. The trial results also demonstrated that these CT-infused worksheet is effective in improving students' mathematical literacy. Novelty: In contrast to earlier studies that focused on literature review, analysed students' CT abilities, or integrated CT into mathematics learning to improve CT abilities, this study integrates unplugged CT into a worksheet to improve junior high school students' mathematical literacy. This CT-infused worksheet has been proven valid, practical and effective as a probability teaching material to support the development of mathematical literacy.

Abstract

This study addresses the issues of the low level of learning independence of students, especially in understanding abstract chemical materials such as chemical bonds, as well as limited learning time, which often results in suboptimal comprehension and the omission of some sub-materials. In addition, the use of media in the learning process rarely incorporates technological advancements. This study aims to determine if a website integrated with Moodle can enhance the learning independence of students in chemical bonding material. This study employed the research and development method using the 4D model, which comprises four stages. However, this study only included three stages, namely define, design, and develop. The target population consisted of 29 eleventh-grade high school students. The instruments used to collect data were validation sheets, an independence questionnaire, and pretest-posttest assessments. The feasibility of the integrated chemistry learning website with Moodle was evaluated through validity and effectiveness tests. The validity test involved three validators, consisting of two lecturers and one teacher. Meanwhile, the effectiveness was analyzed using the n-gain from the results of the independence questionnaire and pretest-posttest assessments. The results of this study indicated that the chemistry learning website integrated with Moodle significantly enhanced the learning independence of students with the validation results of 5 for content validity and 4 for construct validity, while the n-gain results from the independence questionnaire and pretest-posttest assessments fall into the high category. In conclusion, this media effectively promoted independence across five indicators of learning independence.

Abstract

Perubahan paradigma pembelajaran menuntut guru memberikan pengalaman belajar siswa melalui integrasi teknologi dalam pembelajaran matematika. Teknologi seharusnya tidak sekedar sebagai media presentasi, tapi mampu mendukung konstruksi pengetahuan siswa, termasuk untuk konten matematika yang abstrak. Namun, kompetensi guru yang beragam dalam pemanfataan teknologi dan berbagai kendala lainnya mengakibatkan guru belum optimal dalam mengintegrasikan teknologi di kelas matematika. Kegitan ini berupaya menguatkan kompetensi guru dalam integrasi teknologi dengan lebih optimal melalui GeoGebra Classroom yang dan simulasi ready-to-use melalui PhET. Kegiatan berupa pelatihan kepada guru matematika SMA/SMK/MA se-Kabupaten Purwodadi dilaksanakan secara luring melalui participant active learning. Dari hasil evaluasi, guru merasa lebih percaya diri dalam mengintegrasikan teknologi, serta memiliki ide dan pengetahuan baru dalam pemanfaatan teknologi dalam pembe;ajaran matematika. Guru juga merasakan manfaat pelatihan, diantaranya peningkatan pengetahuan dan wawasan profesional guru, serta dukungan pengembangan perangkat pembelajaran.

Abstract

Asesmen Nasional Berbasis Kompetensi (ANBK) is a change from the Ujian Nasional Berbasis Kompetensi (UNBK) which is an assessment program carried out on the quality of schools or educational units. The purpose of this training is to provide training related to understanding and knowledge while at the same time compiling national exam questions for mathematics teachers at SMP/MTs Muhammadiyah in Klaten regarding the preparation of UNBK questions containing HOTS. The method used in this training is an interactive method between the facilitator and the teacher so that the teacher can understand and ask questions directly about the preparation of the UN questions. The training provided is able to increase the knowledge and skills of teachers in preparing exam questions directly by implementing HOTS questions.

Abstract

Penelitian ini dilatarbelakangi oleh kecenderungan siswa untuk berfokus pada penyelesaian prosedural tanpa melakukan peninjauan kembali terhadap proses berpikirnya, terutama dalam memecahkan masalah real-life. Penelitian ini bertujuan untuk menganalisis kemampuan berpikir reflektif matematis siswa pada materi statistika serta mengidentifikasi hambatan yang dialami selama proses tersebut. Penelitian ini menggunakan pendekatan deskriptif kualitatif dengan melibatkan 36 siswa dari salah satu kelas X di SMA Negeri 1 Kartasura. Data penelitian dikumpulkan melalui tes tertulis dan wawancara. Enam siswa dipilih secara purposive berdasarkan kategori kemampuan matematis, yaitu tinggi, sedang, dan rendah. Analisis data dilakukan melalui tiga tahapan, yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa siswa dengan kemampuan tinggi mampu memenuhi seluruh indikator berpikir reflektif, sedangkan siswa dengan kemampuan sedang dan rendah hanya memenuhi sebagian indikator. Hambatan yang ditemukan meliputi kesulitan dalam memahami masalah kontekstual, keterbatasan dalam memantau proses penyelesaian, serta kurang optimalnya kemampuan refleksi dan interpretasi. Dengan demikian, kemampuan berpikir reflektif matematis siswa menunjukkan adanya perbedaan sekaligus hambatan pada setiap tingkat kemampuan matematis.
