Since didactics studies the process of teaching and learning, one important aspect is the interaction that exists between the agents involoved: the teachers, the student and the content (the knowledge to acquire).
In the triangle, it can be seen that this is a relationship among the three components where the teaches must interact with the student to mantain a good rapport and to make this process easier to develop. Also, we have the relation teacher-content-student where the teacher has to select the useful information about any topic that he/she is going to present during the class to make the receiver (student) understand the data presented through experimentation with the material in order to learn beacuse the teacher not only has to present a topic, but he/she has to make the student interact with the information.
To make possible this interaction, some teaching and learning strategies must be included since as mentiones before, the teacher is the one in charge of delivering the information in a way that the student understands and learns; in other words, the purpose is to transform the scientific and academic knowledge into objects of learning. This strategies are necessary to achieve the goal/s of the class and can be used to monitor and evaluate the performance of both, the teacher and the student.
The teacher have to help the student to identify the strategies he/she is going to use. This agent focuses on how students learn individually to know which topics are suitable for them to learn better.
When this interaction happens, the student has the opportunity to interact with knowledge while he/she constructs new experiences and incorporates new meanings to the brain. After the content is delivered to the students, he/she have to put into practice this knowledge linked with the previous lessons and strategies.
