Section Title  Primary information  Description and Notes  Suggested resources 

Lesson Length  The expected lesson length will be approximately one hour 
Some variation possible. Assessment Level 1 

Students  The lesson is suitable for KS3 and KS4 students  Since this is a new specification, the lesson is suitable for Year 7 to 9 students and differentiated by outcome  
Overall Focus  This lesson will look at some of the logic that is used in computing and program writing. 
This lesson will look at the main ways that logic is used in computer to make the code more efficient. 
Lesson Links: 1, 2, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39 
Key words  logic  These words need to be reinforced throughout the series of lessons  
Assessment  predict the outcome of statements containing AND, NOT and OR in information searches 
Evidence here will be student's own work and assessor observations. 

Key Questions  Some questions to get learners thinking about the topics  Some questions about how to improve the effectiveness and efficiency of searching for information.  What methods can we deploy to help make finding information easier? We all have huge amounts of data and a wealth at our fingertips, but how do we get the information we need and not waste our time on pointless searches? 
Learning Objectives 

Students should be introduced to logical functions and operations and be comfortable using them and modifying them. 
If you are using the Learning Machine learning system, students can add their comments and material to this site as evidence of their growing understanding. The site, if used consistently, will show progression via charts of activity and outcomes. 
Teaching and Learning Elements 


Computers are basically truth machines. They have to decide if something is true or false, although they do it very quickly. Sometimes, yes/no is too direct. Logic operators give more subtlety to this basic function. I want X and Y, but not Z. This gives the computer a number of options to find something very exact. Is it possible to predict the outcome of anything that involves these logical operators? Can you devise a way to test this in practise. Some good examples of the operators is here for discussion. 
Lesson Structure  Possible structure 

Students can devise an experiment to see how effective (or not) logical operators are. How much do they improve searches. They can divide into a control group who don't use them and one that does. What difference does it make? Can they be used in multiple combinations? Is there a way to organise their own data on the network or home computer to make it easier to find. Will these operators help? 
Homework  Write a short reflective piece on logic. Does it help?  Students can vary their homework depending on their level of understanding  Students can continue to document their experience on their portfolio system for assessment
