Teaching a Computer to “See Things” by Doodling

 

Introduction

Recently I came across an awesome tool that google released to assist in creating the world’s largest doodling data set of common objects. I used it in my weekly ICT lesson with Grade 8’s & 9’s and was surprised by how much they enjoyed it. We also managed to have a brief discussion of what a neural network is and how researchers  are trying to use them to teach computers to recognise common objects.

Neural Network – “A computer system modelled on the human brain and nervous system.”

Outline of Lesson

  • Begin the lesson by asking the class if they know what a neural network is?
  • They probably wont, then ask if they have ever heard of AI?
  • Most will have, and some will even want to tell an interesting story about what they’ve heard.
  • Explain how one of the challenges for AI is getting computers to recognise common objects.
  • One type of solution is to have a massive human generated Database to compare things to.
  • And today we are going to make our contribution to that Database.
  • Begin use of Google’s Doodling Tool
  • The learners normally enjoy using the Tool for at least 30 min.

GeoGuesser – What an awesome way to learn about the Geography of the World

Introduction:

Recently I came across an awesome game called  Geoguessr for helping students learn about the Geography of the world. The basic structure of the game is as follows. An image of a place in the world appears on the screen and you then have to drop a pin on a map to guess where you think the location is. As you progress in the game, you start to get better at interpreting clues hidden in the pictures. I can’t think of a more exciting way to learn about the cities of the world and be exposed to the variety of settings the world has to offer.
