Development of Science Literacy-Based Cognitive E-Assessments on Chemical Bonds
Abstract
Abstract This study aims to develop scientific literacy-based cognitive e-assessments on chemical bonds and describe the validity, teacher responses, and student responses to the developed e-assessment. The research design used in this study was a research and development (R and D) design according to Gall, Borg, and Gall (1996). The instruments used in this study were expert validation questionnaires, teacher response questionnaires, and student response questionnaires. The data obtained from validators, teachers, and students were then analyzed by descriptive statistical analysis method. This scientific literacy-based cognitive e-assessment uses 4 aspects of scientific literacy, namely aspects about the knowledge needed for intelligent participation in science-based social problems, aspects about the ability to think critically about science and dealing with scientific expertise, aspects about understanding science and its applications, and aspects about understanding science and its applications. knowledge of the risks and benefits of science. This e-assessment was created to measure students' scientific literacy. The results of expert validation and teacher responses on aspects of content suitability, construction aspects, and readability aspects indicate a very feasible category. The results of student responses on the construction aspect and the readability aspect showed the criteria were very feasible. Thus, the scientific literacy-based cognitive E-assessment on the chemical bonding material developed can be said to be valid and feasible to use.
Keywords cognitive e-assessment, chemical bonding, scientific literacy.
Abstrak Penelitian ini bertujuan untuk mengembangkan e-asesmen kognitif berbasis literasi sains pada materi ikatan kimia dan mendeskripsikan validitas, tanggapan guru, dan tanggapan siswa terhadap e-assesmen yang dikembangkan. Desain penelitian yang digunakan dalam penelitian ini adalah desain penelitian dan pengembangan (R dan D) menurut Gall, Borg, dan Gall (1996). Instrumen yang digunakan dalam penelitian ini yaitu angket validasi ahli, angket tanggapan guru, dan angket tanggapan siswa. Data yang diperoleh dari validator, guru, dan siswa yang kemudian dianalisis dengan metode analisis statistik deskriptif. E-asesmen kognitif berbasis literasi sains ini menggunakan 4 aspek literasi sains, yaitu aspek tentang pengetahuan yang dibutuhkan untuk partisipasi cerdas dalam masalah sosial berbasis sains, aspek tentang kemampuan berpikir kritis tentang sains dan menangani keahlian ilmiah, aspek tentang memahami sains dan aplikasinya, dan aspek pengetahuan tentang risiko dan manfaat sains. E-asesmen ini dibuat untuk mengukur literasi sains siswa. Hasil validasi ahli dan tanggapan guru pada aspek kesesuaian isi, aspek konstruksi, dan aspek keterbacaan menunjukkan kategori sangat layak. Hasil tanggapan siswa pada aspek konstruksi dan aspek keterbacaan menunjukkan kriteria sangat layak. Dengan demikian, E-asesmen kognitif berbasis literasi sains pada materi ikatan kimia yang dikembangkan dapat dikatakan valid dan layak digunakan.
Kata kunci e-asesmen kognitif, ikatan kimia, literasi sains.
