|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 at the ideas behind the transmission of data over different media types and any associated bandwidth issues. It also takes a look at cost as an aspect of the digital divide.||The lesson will look at how data is transmitted by different media, in particular to compare the performance of cables versus wireless transmission methods and how this relates to cost.|
|Key words||bandwidth, fibre optic, Ethernet, wireless, digital divide||These words need to be reinforced throughout the series of lessons|
|Assessment||compare the performance of cable and wireless connections||Evidence here will be the students showing a basic understanding of the main differences between these transmission types and any cost issues||Explore different cable transmission speeds if possible. Investigate cable structures and look into how wireless signals work.|
|Key Questions||Some questions to get learners thinking about the topics||Some questions and examples will get the students thinking about what controls transmissions and what the restrictions are on bandwidth.||What are some of the issues associated with each type? What is the speed difference between basic types: Wi-Fi vs. Ethernet vs. Fibre. Are there cost issues? Can everyone get the best possible Internet services?|
Students will need to understand the hardware and software restrictions on transmission of data and some of the issues related to each type.
They need to investigate the cost of each type and look at issues of social inclusion.
|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 physical elements determine the speed and throughput of data transmissions and how other factors can affect them, such as microwave ovens affecting mobile Wi-Fi badly.
There is no need to go into great details, but it would be useful to explore some of the hardware and software used in transmissions.
Begin to look at issues of access and fairness.
|Lesson Structure||Possible structure||
|Homework||Get students to produce a blog on their idea of the future of the Internet.||Students can vary their homework depending on their level of understanding.||Get students to document their experience on their portfolio system for assessment|
