This document provides an overview of the module "Module Structure Web 2.0" which covers advanced web technologies and Web 2.0. The module consists of tutorials, lectures, and two coursework assessments. It will help students develop an understanding of technologies like XML, AJAX, web security, and regular expressions as well as issues around modern web development and Web 2.0. Students are encouraged to take an active role in their learning through online resources and maintaining notes. They can get help from tutorials, lectures, emailing the lecturer, or online searches.

Learning Computer-related Subjects
Changing technologies require “life-long learning”.
Knowledge about computers is never complete.
It is usually better to know where and how to find solutions to
arising problems than to memorise solutions that worked in
the past.
It is useful to maintain logbooks (weblogs) to avoid having to
search for the same solution twice.
The best computer textbooks are

the past.
It is useful to maintain logbooks (weblogs) to avoid having to

The best computer textbooks are
Google (or similar search engines) and Wikipedia.

7. Module Structure Web 2.0
Module Structure: Tutorials
The learning materials are arranged in exercises simulating
real web applications.
The learning materials are more technology-oriented than
fact-oriented. Students are not required to learn anything “by
heart”.
All assessments are “open-book” and simulate problems as
occurring in real web applications.
On-line materials (including search engines) should be used
for the coursework - but all resources must be quoted to avoid
plagiarism.

8. Module Structure Web 2.0
Module Structure: Lectures
The lectures support the tutorials.
The lectures include some structured presentations (for
introduction and overview of topics) but also time for class
discussion, group exercises and opportunities for asking
questions.
Due to the nature of the subject matter, the lectures will not
be “complete”.
Students are encouraged to complement the lecture materials
by reading web resources. The module website provides some
starting points.
The reason for providing learning materials in a more flexible
manner is to encourage students to take ownership and control of
their learning.

Getting Help with the Module Materials or Coursework
Ask questions during the tutorials or lectures.
Email questions to the lecturer.
Check the module website for FAQs and announcements.
Type your question into Google. (Note: use quotation marks
around phrases, e.g. “Server-side web languages”).
Ask fellow students (but not if the problems relate to the
coursework!)
Request an appointment with the lecturer.

10. Module Structure Web 2.0
Using a Non-Napier Webserver
As a learning experience, students may want to explore using
a webserver outside the university or install a webserver on
their laptop.
The webserver used needs to support PHP (or Perl/CGI).
Linux and Mac OS X: webservers are pre-installed.
On a PC: a webserver is easy to install using WAMP, etc.
But: Napier University will not be responsible for any problems
(technical, legal, financial or other) that students encounter if
using a non-Napier resource.

Web 2.0: Definition and History
There is no exact definition for Web 2.0.
Older technologies retrospectively named Web 1.0
tend to be static with no user involvement.
Named after the “O’Reilly Media Web 2.0 conference” in 2004.

Freemium business model
Venture capitalist Fred Wilson’s Blog on 23 March 2006:
Give your service away for free, possibly ad supported but
maybe not, acquire a lot of customers very efficiently
through word of mouth, referral networks, organic search
marketing, etc., then offer premium priced value added
services or an enhanced version of your service to your
customer base.
Used for Shareware and Open Source software.
