You know you’ve watched a bit too much CSI when you start planing lessons around it. The start of next half term for my GCSE & AS Computing people will commence with a spreadsheet. Yep, a spreadsheet.
The plan is to introduce some practice of the binary & hexadecmial that they looked at last hald term and combine this with an understanding of bitmap and vector images and the theory behind them. (It’s the zoom in, enhance that image ongoing joke that prompted the whole project) There is a real possibility of this topic being very dry and losing the interest that was sparked in the first half term with programming. When it’s dry, it’s just as boring to teach as it is to be taught. Enter CSI School…
The spreadsheet guides them through a set of tasks where they answer questions and undertake practical activities from picking out hexadecimal colours from a bitmap to find a secret message, to writing a program to calculate maximum file size, to using a drawing list to create a vector.
I’m planning on this taking a good 6 lessons for them to go through all the tasks and create a set of written notes (A Level) to highlight the key terminology.
It looks like fun. So, here’s a copy of the resources basically because I’m lovely.
Note: You’ll also need the BMP file and password for the ‘nope’ sheet. Please drop me a message and I’ll email them to you (wordpress don’t allow bitmap uploads)
