I did Technasium as secondary education, this means atheneum with an extra subject called Research and Design (R and D).
R and D is a subject in which you will be doing a project for a couple of months. During these projects you start with making a plan, when do we have to finish what and who is going to do it? After that you will have to research into the subject. What is done after this depends on the subject. It can range from making a design for an area to doing tests with models to handing a report stating who is the killer. This has tought me a lot of creative thinking, how to present your design, search for solutions and how to defend your design but also know when the other is right. In the first four years the projects where given to us, however the last two years we had to find the projects ourselves. This also thought me how to find clients and how to keep in contact with them.
Here is a brief summary of all the projects I have done in the last six years. After this are a couple of projects I wanted to point out.
