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 criterion will be broken down into 3 lessons to look at the main components of server services. The lesson will look at how mail based services are handled by servers.

Lesson Links: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39

Key words email, mail server, SMTP, POP, Spam, IMAP These words need to be reinforced throughout the series of lessons  
Assessment Identify key services provided by Internet servers Evidence here will be the students showing a basic understanding of the main terms and being able to demonstrate they know how mail services work. Explore different mail servers and services, if possible, showing some of the systems in operation.  Look at the elements of mail servers and clients and how they fit together.
Key Questions Some questions to get learners thinking about the topics Some questions and examples will get the students thinking about what mail services are and what they take for granted when using the Internet in their daily lives. The Internet is relatively standards free.  Most of what students do on the Internet can be done on virtually any Internet enabled device.  Why is this?
Learning Objectives
  • To understand the key aspects and technologies of mail serving
  • To describe and explain, with examples, how mail is served
  • To understand how mail servers function

Students will need to understand some of the key elements of mail serving such as IMAP, POP, filters, clients etc.

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
  • introduction to mail server software
  • detailed look at the main clients such as desktop and web based
  • Students can break into groups and work on some basics of mail
  • Class discussion and evaluation of the wider uses of Internet technology for mail
  • Summarize the key points and reinforce the importance of open standards

In this lesson we need to give students some understanding of some of the elements of mail systems such as the basic structure of addresses and how clients deal wth this.  Some practical exercises on this would be helpful with discussions about open standards and net neutrality.

There is no need to go into great details, but it would be useful to explore some of the addressing functions and filtering of mail.

Using a Virtual Machine is an easy way to play with mail server technology without messing up your own network. 

 
Lesson Structure Possible structure
  1. investigate mail servers
  2. show students some more examples of mail headers and discuss what the terms mean
  3. group work to work on some of their own views and examples
  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

Mail server graphic

The Warrior on the Net video is useful as an overview of the main elements of web services, including mail.

A short guide on how to read email headers by Google support can be found here.

See if the IT team can show students their Internet mail server set up and some of the configuration options.

Some videos here explain some of the issues with virtual machines if they will be used to explain some of these systems and services.

See if spam is obvious:

Spam detection software, running on the system "x.x", has identified this incoming email as possible spam.  The original message has been attached to this so you can view it or label similar future email.  If you have any questions, see the administrator of that system for details.
Homework Get students to bring in some print out of the header of an email they consider spam. Students can vary their homework depending on their level of understanding. Get students to document their experience on their portfolio system for assessment
