Resumen
This study aims to describe the implementation of online learning that is applied today, and to develop a blended learning model as a strategy to provide student services according to the diversity of potential, needs, interests, and learning speeds. This study used research and development design. Several stages were carried out, namely, conducting literature studies, planning, organizing, mapping basic competencies, carrying out learning activities, reporting, and dissemination. The preliminary research samples included 10,466 students, and the samples for the blended learning model trial included 144 students through random sampling. The results showed that many students were happy to study at home, whereas others were happy to study at school. The facilities to support online learning at home were sufficient. The online learning presented by the teachers was quite interesting and most parents support it. Based on these findings, a blended learning model was developed. The results of the model trial show that blended learning is very useful and there is a significant increase in student learning outcomes. The blended learning model is very effective at supporting online learning. It can provide optimal services to students according to their talents, interests, and abilities. For that, a special strategy is needed and the cooperation of all the elements of the school. The development of an IT-based management system is very helpful in monitoring the progress of students and increasing the awareness of teachers and parents in overseeing the success of learning. The blended learning model in high school can be one of the models for schools that implement a semester credit system.
