Development of a drinking water engineering module for students at secondary schools

In the Netherlands, the amount of contact hours for mathematics, physics and chemistry is decreasing at secondary schools. To compensate for this decrease in knowledge a new course has been developed. This course is a combination of Beta-courses and deals with the application of fundamental theory in daily practice. The course is called NLT, standing for Natuur, Leven and Techniek (in the English language “Nature, Life and Technology”). In 2008, a team consisting of two specialists from the drinking water department and a coordinator from the science education department, all of Delft University of Technology, and four teachers from two secondary schools, started the development of a new NLT module on drinking water treatment. In this paper, the development process of the module is described.
