Welcome to part 3 of the 3D printers series of posts. So far we have covered the basics of 3D printing as a STEAM project and covered the building of a 3D printer, the electronics and keeping safe in an education environment. In this part, we will cover the building of the enclosure and the raw materials used to print. This essentially covers engineering, mathematics, art, and Science.

Welcome to part 2 of this series, which will discuss how 3D printers cover a wide range of STEAM components in education. In part 1, I laid the groundwork and covered the basics, such as the history of 3D printers, the process of printing from start to finish and how the different aspects met the STEAM components.

In part 2, I will discuss building the printer and the electronics, along with the association Technology and Engineering components of STEAM.

3D printers are all the rage right now. There are people creating small models out of them, building houses out of them, and most recently, a whole car (most of a car) was built using a 3D printer. I've been interested in them for the longest while, but only in the past few years have they become affordable enough to gain traction with the hobbyist crowd, like me. You can pick up a relatively good one for less than £200, and the best thing about that is you can immediately (once you get it up and running, of course), start printing upgrades for the printer which further improves the quality of future prints.

With the huge reduction in price, this now becomes available as a tool for education. Yes, some schools probably already had 3D printers. However, they were most likely the kind that cost thousands of pounds, and no one was allowed to use it, cos it cost thousands of pounds. Now, they cost hundreds, so depending on the school you're in, they are well within the budget of single departments. So they can now feature much more widely in school curricula, and as department clubs and enrichment programs. This is exactly what this post or series of posts is aimed at, as it is way more fun if the students taking part already have an interest, and don't have to worry about the pressures of mandetory assessments and grading.

So how and where can this feature in your subject?

I recently had the task of developing a curriculum to teach Python programming and one issue that came up was which IDE to use. There are plenty of Python IDEs to choose from, which is a blessing and a curse. With so many out there, what factors do you consider? Let's add some background information. The students would be grade 7 (UK year 8, age 12/13), beginners in text based programming with a background in block based programming having done, Scratch, Ardublockly and Kodu in previous years. To add to that, cost, as always, is an issue. To focus the discussion a little further, I was able to narrow the choices down to two main programs, PyCharm and IDLE. PyCharm by Jetbrains, and IDLE available with the Python download. I'd like to discuss these two in the context of teaching but will also discuss the online repl.it service briefly as well...

Welcome to part 5 of my Paperless Classroom series of blog posts. In part 1 I discussed general paperless technology; in part 2 I talked about my own classroom progression through the available tools; in part 3 I discussed my own tool I created and used in the classroom; and in part 4, I discussed my second version of the tool I created. In part 5, I want to discuss what has happened since I created it, and what I hope it will  become. This post will contain a few excuses and will be a bit more personal than many of the other posts, which I intentionally try and stay away from. However, I feel that it's necessary to give a full explanation of thoughts and actions. So, here we go...
