Despite the advantages of e-learning, skeptics still hold that online studying is more difficult than traditional learning (177). For example, learners who are not well versed in self-directed learning could procrastinate due to the lack of a physical teacher and subsequently suffer declines in their performance. Sun and Chen argue that some learners lack the needed technological resources such as broadband, which hamper the smooth delivery of online lessons (178). On the other hand Hart and others note that the majority of online learners spend little time, approximately three hours per week, which reduces their content grasping. In contrast, face-to-face classes ensure learners spend at least seven hours a week on course material; hence such students demonstrate better performance. Moreover, online learning often calls for modification of some course materials to suit the particular mode of teaching (Sun and Chen 167). It, therefore, calls for considerable investments from schools for its successful implementation
