Methodology
Project Based Learning: Teachers will form groups of 3 persons according their teaching subject (1 team of Chemistry teachers, another team of history teachers and so on). Each team will design and print a simple object for their classroom (for example the molecular construction of water or the column of the Parthenon temple)
Demonstration: The hardware, parts and basic setup of a 3d printer will be explained to the trainees
Learning by doing: the trainees will actively engaged with the 3d printing process, trying to print objects useful for their lessons.
Formative assessment: during the course the trainers will estimate the level of trainees and adjust the content of the course according to the individual needs of the trainees.

Preparation
Trainees will receive a questionnaire, which will provide information on their teaching subject, teaching background, qualifications, and any previous experience with 3d printing.

Follow up
Trainees will be supported by the e-Nable Greece Erasmus+ trainees Facebook Group. The group is full of instructions, photos and videos of how to use/set a 3d printer and design/print educational materials. The administrators of the Group will give instant feedback to any trainees’ question or problem.
In addition, trainees will be provided the educational material of the course in copies and in digital files. This material may be used by the trainees for presentation to their own organizations in order to generate interest in 3d printing in the classroom.
