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 focus for this criterion is an understanding of some of the range of services offered by servers in a network.  Most students will use these services, such as file management and email, but perhaps without a better understanding of how they all function.

The focus here can be on web services

Students should be allowed to see a network in operation and go to the school's server room if possible to see the hardware in situ for more meaning.

They can discuss with the network team some of the services on offer and some of the issues related to the services.

Lesson Links: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 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 network, server, client, web servers, FTP servers, database servers, E-mail servers, file servers, print servers. These words need to be reinforced throughout the series of lessons  
Assessment

identify a range of servers and services provided by servers to networks

Evidence here will be student's own work, eportfolios and assessor observations  
Key Questions Some questions to get learners thinking about the topics Students will need to look at some different services that are offered in the school network What does a web server do?  What is a web page and how do you get to it?  What is different about web pages compared to normal pages?  How are they "served" and to who?
Learning Objectives
  • understand the services offered by servers in a network
  • be able to explain the main services
  • be able to discuss the difference between services

Students should show that they understand how a basic web server works and some of its key attributes.

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
  • Overview of web servers
  • Detailed look at web servers and services
  • Students can break into groups and work on researching web services
  • Class discussion and examples of their findings back to class
  • Group or individual work on their own understanding

Students can be shown and discuss in very broad terms about how web servers work and how they control access to servers with web content.  They should have a basic understanding of web services as well as links to database driven web services as required.

Use some of the student's ideas and examples to flesh out a solid understanding before progressing

Question students about how and why they did what they did.  Check for understanding.

 

Lesson Structure Possible structure
  1. Introduction and basic overview of web servers
  2. investigate in detail web pages and database web sites
  3. look at and discuss web technologies like PHP and JavaScript.
  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

Web server image Most modern server operating systems now come with some type of web server software.  This is a software system that allows files such as web pages, images, videos and text to be sent to other computer's browsers.  The most common web server is Apache logo which currently serves over 70% of the world's web sites.  There is also Nginx logo which is becoming more popular.  Windows IIS server software does not serve many websites.

The server holds pages made with programming languages such as HTML (Hyper Text Markup Language), PHP and JavaScript to make exciting web pages.  People access the web servers pages from their own computers via their browsers.

Many web sites use databases to store information about users or send additional information to users such as products in a store catalogue.  The most common database is an open source one called MySQL logo, though Oracle is the biggest and is one of the largest technology companies.

Homework Get students to create a basic guide to HTML. Students can vary their homework depending on their level of understanding Get students to document their experience on their portfolio system for assessment
