Moodle: Developing an Interactive Timeline Widget
by
Nicholas Freear | October 2011 | Moodle Open Source
In this article by Nicholas Freear, author of Moodle 2 for Teaching 4-9 Year Olds Beginner's Guide, we will develop an interactive timeline widget, potentially with the help and collaboration of our pupils. This will help your pupils visualize some historic events, and the temporal relationships between them. The timeline will contain images and links to other resources. You can use the timeline to foster discussion, which for older pupils may take place in a Moodle forum.
And we will use Moodle to set homework for our pupils. No more lugging 30 exercise books home to mark!
Specifically, we will cover the following topics:
- Introducing the SIMILE timeline widget
- Installing a text editor
- Creating the timeline data file
- Installing the Timeline Widget filter
Building HTML5 Pages from Scratch
by
David Karlins | October 2011 | Web Development
In this article by David Karlins, author of Dreamweaver CS5.5 Mobile and Web Development with HTML5, CSS3, and jQuery, we will learn to build web pages in Dreamweaver relying entirely on HTML5 layout tags. There are four things we will accomplish by learning to do that:
- Building page layouts relying exclusively on HTML5 layouts will hone our skills at using these new tools for page design, and introduce HTML5 Code Hints in Dreamweaver
- Relying on standardized, defined HTML5 layout elements (as opposed to custom-defined, irregularly implemented Div tags) streamlines page design
- There are actual, significant real-world scenarios where building pages relying exclusively on HTML5 layout elements is the best way to design them (for example, when designing pages for iPhones or iPads)
- There are functional advantages beyond design considerations for organizing page content in HTML5 layout elements. We will examine those advantages as we build HTML5 pages

Introduction to Moodle
by
William Rice | September 2011 | e-Learning Moodle Open Source
Moodle is a free learning management system that allows you to create powerful, flexible, and engaging online learning experiences. We use the phrase "online learning experiences" instead of "online courses" deliberately. The phrase "online course" often connotes a sequential series of web pages, some images, maybe a few animations, and a quiz, provided online. There might also be some email or bulletin board communication among the teacher and students. However, online learning can be much more engaging than that.
In this article by William Rice, author of Moodle 2.0 E-Learning Course Development, we will give you an introduction to Moodle.
