Factor analysis of the computer network to study the degree of task difficulty

In online class teaching, there are several elements related to online learning tasks: online resources, teaching goals, materials, activities, the roles of teachers and students, activity backgrounds and the supervision and assessment of tasks. The online learning tasks of different degrees of difficulty are the results of different combinations of these elements above. If one of them changes, the degree of difficulty of the whole task would change. The research shows, when all the elements are at an easy level, the whole task would be easy; vice versa.
