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

Multivalued mapping in normed space has been extensively studied in Mathematical analysis. One example of multivalued mapping is normalized duality mapping. This mapping leads us to another example of multivalued operator, named accretive operator, which is also a multivalued operator. This study was aimed to examine the basic concepts of accretive and maccretive operator. Furthermore, discussion on some properties of accretive and m-accretive operator was provided.

Abstract

Salah satu tuntutan belajar abad ke-21 di bidang komunikasi, kolaborasi, dan berpikir kritis adalah HOTS. Terdapat banyak siswa yang belum memahami langkah-langkah penyelesaian masalah, terutama dalam menjawab soal-soal HOTS yang menuntut siswa untuk menggunakan kemampuan berpikir kritis mereka. Penelitian ini bertujuan untuk menganalisis kemampuan berpikir kritis peserta didik SMK kelas 10 dalam menyelesaikan soal HOTS materi barisan dan deret aritmetika ditinjau dari Self Regulated Learning. Penelitian ini merupakan penelitian kualitatif. Subjek penelitian ini adalah siswa kelas 10 SMK Negeri 4 jurusan Teknik Jaringan Komputer dan Telekomunikasi. Pengambilan data dimulai dengan pengisian instrument angket Self Regulated Learning dan soal tes berpikir kritis kemudian wawancara. Hasil penelitian ini adalah semakin tinggi tingkat kriteria Self Regulated Learning suatu subjek, maka semakin banyak indikator berpikir kritis yang dapat subjek penuhi, yang berarti semakin tinggi tingkat pemahaman dan kemampuan menemukan soalusi matematis sebuah permasalahan. Akibat langsung dari hasil penelitian ini adalah memberikan sebuah gambaran mengenai tingkat berpikir kritis ditinjau dari Self Regulated Learning sebagai evaluasi dalam mengimplementasikan soal HOTS dalam pembelajaran.

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.
