Evaluating the impact of new teaching practices - computing

These videos guide you through the process of evaluating the impact of changes you make to teaching approaches in your classroom. The evaluation approaches described here will enable you to tell whether new approaches are more effective than what they have replaced. You'll be able to make evidence-informed...

Session 5 - Data Compression Algorithms

This session looks at how images and sound use compression to reduce their size when storing them or transferring them over the Internet or on devices to save space. In the session you will have a look at how an algorithm can be used to compress this data.

All the answers are to be written in the workbook....

Session 6 - Error Detection and Correction

The purpose of session 6 is to introduce you to how computers detect errors in data and where the error occurs. It will introduce you to the idea of parity bits and parity check to determine if the data has been corrupted. This session requires the use of a pack of cards or cards with a colour on one side.


Session 1 - Introduction to Binary Digits

This session introduces you to the use of binary digits to represent basic images and the key terms for capacity. During the session you will investigate 4-bit binary numbers and look at the patterns in the numbers.

  1. Open Slides and read through slides 2 and 3 to get an understanding of the session that...

Session 2 - Binary Numbers

This session introduces you to converting denary or base 10 numbers to binary digits and back again. It consists of two files, a set of slides explaining how binary conversions work and a worksheet.

  1. Read the slides in Slides - Binary Digits about binary digits. Make sure you are clear on how the values...

Session 3 - Digital Images

This is a short session looking at the structure of pixels in a digital image. It will help you understand how the number of bits used per pixel determines the number of colours that are available.

  1. Open the Information document and read through the information about digital images. Look at how using...

Session 4 - Sampling Sound

This session explains how sound is converted from a continuous analogue sound that we hear in the real world and converts it into a digital format of 1s and 0s that can be used and played back by a computer. The session has a set of slides to read through and a worksheet.

  1. Read slides 1 and 2 . This...
