Thanks to online schools, students have found a new way of learning. This new "system" of education provides many advantages for students. On the one hand, they have complete freedom to decide when they will access information and when they will do the available exercises related to each course. On the other hand, they give students the opportunity to access among a variety of degrees concerning any field of knowledge worldwide. Another interesting thing concerning e-learning is the possibility of self-evaluation. With respect to second language learning for example, there is a variety of websites that provide students with the possibility of working on grammar tests and then knowing about their mistakes. This gives a certain degree of autonomy in the learning-teaching process. The figure of the online tutor is also crucial in online schools. Questions can be sent to the tutor and be answered immediately, as long as he or she is online, of course.

When we hear about online schools we tend to think of courses for students. However, there are some companies such as “Anpe”- http://www.anpesindicato.org/index.htm- which offer professional courses for training teachers on didactic matters such as school curriculum, methodology and evaluation. These courses seem to be useful for teachers since they offer a variety of procedures to be followed by educators who want to be successful in their task. An example is a course called "Didactic units and its application in the classroom" (Elaboración de unidades didácticas y su aplicación en el aula).

In recent years there has been a demand for courses addressed to teachers who want to be trained on didactic techniques in order to “teach better” and also to cope with real problems in the context of a classroom. The learning- teaching process is influenced by many factors such as students’ motivation, learning capacities, learning styles, students’ interests and expectations in life, cultural background, religious beliefs and the kind of interaction between teacher-student and interaction within the group.

Therefore, the necessity of knowing how to teach has promoted the appearance of online schools for teachers especially, when dealing with students in the Primary and Secondary education, where more attention to individual needs is required.
