Learning Experience Plan 3: Data Representation

1. Teaching and learning adjustments

1.1. Assist students who may be unfamiliar with devices. Support low ability students and EAL/D students were necessary. Provide extension activity for AA students – Think of your own digital device and write down its purpose and solution.

2. Conclusion: 1. Invite students to decode a message you have provided using the binary code e.g. I love computer science.

3. Body: Explanation: 1. What is data? Computer data is information generated, processed or stored by a computer. This information may be in the form of text documents, images, videos, audio clips, software programs using a digital system. 2. Explain to students that data can be represented using codes and symbols which is interpreted by a digital system. 3. Explore different representations of data and their purposes: - Aboriginal and Torres Strait Islander art and symbols. - Morse code - Pictographs (All systems use symbols to represent information, data). Activity: 4. Inform students they will understand what is like to be a computer storing data using binary codes to create messages. - Complete a demonstration of how to use the binary decoder key and binary strips to write their initials in the binary template. - Instruct students to use the binary strips and decoder to write their initials. Extension Activity: 5. Allow students who have completed the activity to encode messages for a partner to decode.

3.1. Focus questions

3.1.1. What is data?

3.1.2. Why was this coding system useful?

4. Learning and leaning strategies

4.1. Introduction: 1. Recap on prior learning experience with discussion and questioning. 2. Provide students with learning objective: ‘I can explore codes and symbols that represent data.’
