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 consolidate abstraction models with a real-world focus and see that they can understand how these operate and use the knowledge This lesson will follow on from the previous lesson and acts as a way to consolidate their learning and understanding, and for them to evidence this understanding through class based observation and their feedback comments

Lesson Links: 1, 2, 3, 4, 5, 6, 7, 8, 9, 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 abstraction, programming language, instruction, open source, digital, file types, variable These words need to be reinforced throughout the series of lessons  
Assessment Use software abstractions that model real world systems Evidence here will come from further observations of their application of their understanding on working models and reflecting on their use and utility.  
Key Questions Some questions to get learners thinking about the topics There are some potentially difficult ideas here, but it should be possible to gently build on their understanding through clear worked examples Try and get the students to think of more real world examples of models using abstraction.
Learning Objectives
  • To understand and try abstractions in meaningful ways
  • To describe and explain, with examples, how abstractions help us test theories and ideas
  • To understand how abstraction software in the real world has benefits to us

Carry on work with material introduced in previous lesson.

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
  • Continue with more detailed examples of abstraction
  • A teacher led demonstration of using abstraction software and changing values
  • Students can break into groups and work on their own examples of abstractions
  • Class discussion and evaluation of the wider uses of abstractions
  • Summarize the key points and reinforce the importance of abstractions

This is a consolidation of the previous lesson material.

This lesson builds upon the previous lesson to progress the student's understanding further through practice and demonstration, interspersed with more detailed questions to check their knowledge.
Lesson Structure Possible structure
  1. check where they have got to in terms of their understanding
  2. show students some more detailed examples of abstract ideas
  3. group work to work on some of their own models and what outputs they are seeing
  4. discuss what they have learned and what they can apply
  5. volunteers to share their work and explain how instructions work
  6. highlight next week's focus and issue homework

It would be useful before hand to have some of these programs added to your network or check that they are accessible and work on your network (i.e. some need java and may not work because of strict network security)

Use PHET logo simulations to explore different forces and phenomena.

Discuss the value of these systems and the effects that can be tried.  Discuss the importance of this type of abstraction.  make sure to check that students understand the process of these systems.  use flow-charts to illustrate.  Students need to be able to read a flow-chart and understand how it works as this is a fundamental example of an algorithm.

Students in groups can explore different abstraction software in the real-world and report to the class their findings.

Homework Get students to come up with a flow-chart model from one of their other curriculum subjects, i.e. creating an oil painting, making a map of the school, building a table in DT etc. Students can vary their homework depending on their level of understanding Get students to document their experience on their portfolio system for assessment
