Teaching Computer Science: Day 17 - Testing times!

Concluding the theme of how data is stored in computers, in this week’s lesson, I got students to create their own revision games for unit 2.1.4 using Zondle. Also, as a little treat, I decided to issue my students with my own test on section 2.1.4 of the GCSE OCR spec. – Binary representation of data.

Lesson 1: Revision

Suggested time: 50 mins

Starter

I started by giving students a quick test that I created using Zondle: 

zondle - games to support learning

Main:

I informed students that they will be creating revision games using a free online creation tool called Zondle.

I demonstrated on the board how to create a game with Zondle and how to add questions. As I demonstrated how to add questions to the game, I asked students to suggest possible questions.

Finally, I gave students their usernames and password to login to Zondle and instructed them to create a series of revision games based on unit 2.1.4. I told students that they could use my example (from the start of the lesson) to help them get started.


Plenary:

Students attempted each other’s revision games.

Main:

I issued each student with a test I created covering the topics in unit 2.1.4 (Binary representation of data) of the OCR GCSE specification. The test is based on sample assessment material and past exam papers released by OCR. (Click on link below)
