|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 continues to look a bit deeper into the idea of restrictions such as contention to look at bottlenecks which can affect networks and data transmission.||The lesson will look at the factors to consider in avoiding bottlenecks and what design elements can be used to address the problems|
|Key words||bandwidth, bottleneck, network diagrams||These words need to be reinforced throughout the series of lessons|
|Assessment||identify potential bottlenecks in network design||Evidence here will be the students showing a basic understanding of the concept of bottlenecks and being able to identify simple cases in diagrams||Explore different network diagrams and discuss the relationship between bandwidth and available devices to explore limitations in designs|
|Key Questions||Some questions to get learners thinking about the topics||Some questions and examples will get the students thinking about what problems might occur with some solutions||What causes bottlenecks to occur? How do you determine what devices can cope with what transmissions? What other factors will cause slow-downs, expected or otherwise. Do you have any examples in your own experience? What was the cause?|
Students will need to understand the different devices and how these cope with traffic. They need to show an awareness of how this can be modified by the right equipment and settings.
They need to investigate designing their own network diagrams to explain how each device has an impact.
They should be familiar with all of the key devices and know enough about their specifications to show how they can be used to avid bottlenecks.
|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||
In this lesson we need to discuss how networks are designed and configured based on pre-set information such as the bandwidth, physical restrictions of cabling and devices used etc. They should be aware of these different elements enough to pick out potential bottlenecks when they see them.
This knowledge can be used to create our own designs or look at designs with flaws and discuss how they can be fixed.
|Lesson Structure||Possible structure||
|Homework||Get students to complete their online network designs for submission.||Students can vary their homework depending on their level of understanding.||Get students to document their experience on their portfolio system for assessment|
