According to Diana Laufenberg, the learning process has to contain several educational failures. In the 20th century the main sources of information and learning were teachers and books bought by people for self-education. Nowadays information is available through the internet and the students should understand how to use it properly for getting the knowledge. During working in different states Diana has used her style of teaching which is allowing students to work individually and by team, to find the ways to get the needed information and to use the acquired information in a right way. This teaching system helps to develop students, it also allows the students to do mistakes, have failures and learn from their own mistakes.
