I teach Physics and Computing at a secondary school in England (I am able to teach Maths and D&T also.) I am very keen on bringing more STEM activities into the school as I really think that the students benefit from a cross-curricular approach. This summer I took myself have taken myself on the Raspberry Pi Certified Educator course. I have tried to run a STEM club but it is difficult as the school are not supportive and have not given me a budget for the last two years, I confess I have spent quite a bit of my own money on kit for the students to use. We build 3d printed Robots, code music, build computer-controlled infinity mirrors, stranger things boards etc etc. The enthusiasm is evident by the number of students coming back at every opportunity. Their coding skills is coming on leaps and bounds as is their confidence. I would like to expand STEM from a club activity to the classroom but the trouble is my Computing HOD wants nothing to do with it, he states that it cannot be used in the KS3/4 Curriculum. Is he right?
