DEVELOPMENT AND IMPLEMENTATION OF AN ONLINE CHEMISTRY COURSE: ADVANTAGES, CHALLENGES AND EXPERIMENTAL RESULTS

The article explores issues related to the use of electronic educational resources (EER) in the educational process, with a particular focus on the study of Chemistry. It presents an analysis of both Ukrainian and international experiences in utilizing EER for organizing distance learning. The findings indicate that electronic educational resources create learning conditions in which students, through the use of digital technologies, become active participants in events and processes, fully interacting with a learning environment that simulates real-world objects and processes. The authors examine the specific features of developing and using an online course to study Chemistry in vocational education institutions. Such a course allows the integration of various electronic resources into a single platform, providing visualization and interactivity in learning a subject that is often challenging for students, as is the case with Chemistry. The article describes the experience of creating an online Chemistry course, detailing the algorithm for its design and course structure. Examples of educational materials, assignments, and the services used for their development are provided. This online course offers several didactic opportunities, such as the ability to dynamically update content, methods, tools, and training formats, demonstrate laboratory experiments, analyze virtual experiments and observations, and implement various types of knowledge assessment for students. The use of an electronic course meets the educational needs of modern students. The article also analyzes the results of initial and final surveys conducted among vocational and technical educational institution students who participated in the study and used the online course to learn chemistry. The analysis of initial survey results revealed that traditional textbooks were considered unengaging and lacking interactivity, whereas post-experiment surveys indicated that most students found the online course more interesting. The analysis of students' academic achievements showed positive progress in mastering the educational material. The main advantages and identified shortcomings of the online course are also discussed.
