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 The lesson focus will be to introduce students to the idea of testing and evaluation: looking for good and bad elements of their work This lesson will build on existing knowledge and practice and work students towards an appreciation of computer models and how they can be improved, where possible

Lesson Links: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 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 abstraction, programming language, instruction, open source, digital, file types, variable These words need to be reinforced throughout the series of lessons  
Assessment Identify strengths and weaknesses in computer models This is an introduction to the ideas of evaluation which students will perhaps not be familiar with.  Evidence will be a basic understanding of key terms through observation.  
Key Questions Some questions to get learners thinking about the topics In most subject areas, students will struggle with finding strengths and weaknesses in their own work or work of others.  Some good questions should be able to help them tease out these ideas. Is there such a thing as a piece of perfect software?  Can computer models be close to reality?  Should they be that close?  What factors make something good or bad?
Learning Objectives
  • To understand and appreciate the importance of reviewing software models
  • To describe and explain, with examples, how computer models can be evaluated in general
  • To understand how computer models are devised and created

Students need to look again at all of the software systems and models they use and start thinking about what makes them good or bad to use.

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
  • Review the previously introduced software systems to look for and discuss their main features
  • A teacher led demonstration of your view of some of these systems, as a guide
  • Students can break into groups and work on their own ideas about the software in general
  • Class discussion and evaluation of the wider uses of good and bad
  • Summarize the key points and reinforce the importance of evaluation

In this lesson we need to give students the tools and knowledge to begin thinking about what makes things good or bad, strong or weak.  They need to start considering the purpose of computer models and therefore how well they meet their design goals.

Use some of the student's own work and share with the group and discuss the quality of the impressions chosen.  Question students about how and why they did what they did.  Check for understanding.

Lesson Structure Possible structure
  1. introduce some of the previous software models and talk in general about their features
  2. show students some more detailed examples of computer systems
  3. group work to work on some of their own views
  4. discuss what they have learned and what they can apply
  5. volunteers to share their work and explain how they came to their opinions
  6. highlight next week's focus and issue homework

All previous software systems and simulations explored and any others that would be useful to introduce evaluation methods and ideas.

Discuss what the systems are supposed to do and how well they do certain things.

Students in groups can explore these systems and discuss amongst themselves what they like or don't like in general.  Is there agreement?  What makes something that everyone likes.

Homework Get students to write a short list, with examples, of computer software or devices they really like or don't like Students can vary their homework depending on their level of understanding Get students to document their experience on their portfolio system for assessment
