STEM in crisis 2015, Obama: “(Science) is more than a school subject, (...). It is an approach to the world, a critical way to understand and explore and engage in the world, and then have the capacity to change that world.” The Bureau of Labor Statistics, 2015 “STEM in crisis or STEM surplus? Yes and yes.” We learn from the study about employment: the academic sector is generally oversupplied, while the government sector and private industry have shortages

From the unstructured feedback… As teachers we kept in touch with the pupils. Some ideas from what they shared: Shortage of time To open safe first in my life Loose connection between task and code More teams sqeezed into the room, not enough space The very spot of the game A possibility to fidget around the laboratory
Our teenagers…. Without useing the net there was no chance to escape A pressure to use the internet ( teenagers) The diver experiment A crossword on physics – mind-blowing, really! The moderator was helping and kind The moderator seemed too bright and frightening Next time we need to study deeper e.g. with unstructured interviews
Thank you for your attention Please, feel free to comment or ask…. This study was funded by the Content Pedagogy Research Program of the Hungarian Academy of Sciences.
