Training a Neuron using Scratch

Image
In a previous post http://compuationalthinking.blogspot.co.uk/2016/11/artificial-neuron-in-scratch.html I used Scratch to build a working artificial neuron.

In this post, the training of a neuron all written in Scratch is tackled. The video shows it action and you can have a go at using the software yourself at the end of the post. The Scratch code can be found at https://scratch.mit.edu/projects/132915502/

Artificial Neuron in Scratch

Image
Instructions:

Set the inputs by pressing the buttons marked input 1 and input 2 (Red is off(False or 0) and Green is on(True or 1))Change the weights by changing weights 1 to 3, wx goes with input x and weight 3 is the bias.To activate the neuron you need to click on the the yellow ball ('the neuron').



The video below show it in action and explains the code.

How to be an Unplugged Artist

A recently released book Teaching Computing Unplugged in Primary Schools  edited by Helen Caldwell (University of Northampton) and Neil Smith (Open University) has a number of interesting chapters by authors who are passionate about how computing is taught in schools. The central theme is unplugged activities, without using computers, but still teach the fundamental of computational thinking.

Ok, confession time. I co-wrote, along with Katharine Childs (Code Club), Chapter 3 Artists so I am biased here, but I believe in the central theme of Unplugged Computing. Computing, and Computational Thinking in general,  is not just about programming and using a computer (though using computers and  programming are vitally important to Computing) but it is also about many other things including problem-solving, being creative and working collaboratively.

Chapter 3 is about linking these computati…
