From face-to-face learning to e-learning through blended learning: An educational image-based software

In the current paper the software and the teaching and examining procedure for the class "Safety and Health on Engineering Worksites" is described. The class is taught in undergraduate university studies and it focuses on worksite organization in terms of time and space, in order to secure, along with the continuous flow of work, the safety of personnel (Accident Prevention Program - APP). The experience acquired over 17 years teaching this class with the traditional method, where professor and students are present in a classroom, is transferred to a new software program that in the first phase assists teaching (blended learning) and replaces traditional examination methods and at a later stage will allow long distance electronic teaching.
