Novel ways to present images and video in a powerpoint presentation

I am constantly looking or new ways to “jazz up” my presentations and recently I cam across two methods that i found quite nice; using an iphone image to encase your videos and creating a photocube effect for presenting images. The Youtube clip below ilustrates how to implement these two ideas

Several teachers have asked me numerous times how can I take advantage of Youtube. Here are some examples

As a teacher I would recommend having your safety search activated on your browser to reduce the chance of any objectionable videos appearing on your screen. Although not 100% guaranteed “ever little bit helps” as the saying goes. The video below illustrates how to activate this safety setting

If you are still a little nervous about using YouTube in the classroom (as you are never guaranteed what other videos will appear in the sidebar).  you can remove all other videos from your screen by cleaning up your screen using a third party service outside youtube

If you school has blocked YouTube in your classroom you can download videos in advance by using websites like just remember to be vigilant with regards to copyright – not everybody puts their videos up on YouTube under a creative commons licence.

Another site I found useful for youtube was Splicd. This site allows you to just show a certain segment of a Youtube video. For example the video may be 15 minutes long but you only want to show your students a video from 2 minutes until 4 minutes.

The best use that I got from youtube was when I asked the students to do the work – this post explain how I set surfing YouTube as an assignment for my students

This post just deals with videos that already exist on YouTube. If you want to post some videos of your on YouTube  – have a look at my post on screencasting

Cleaning up Youtube for your classroom

Youtube can be a fabulous classroom resource but can some schools are cautious about using it in the classroom because they are concerned about the videos and adverts that appear in the sidebars. “” offers a potential solution for teachers. This site cleans out all the clutter and gives you just a video.  Furthermore there is a quick button that you can add to your browser so that you can go to a video, click on “Purify” in your bookmark bar and instantly have a clean video

What is Screencasting?

This post contains support mateiral for the Screencasting workshop at the Edtech 2012 conference in NUI Maynooth. Thank you so much to my co-presenter of the workshop Damien Raftery from IT Carlow (@damienraftery)

A screencast is a digital movie in which the setting is partly or wholly a computer screen, and in which audionarration describes the on-screen action. It’s not a new idea. The screencaster’s tools—for video capture, editing, and production of compressed files—have long been used to market software products, and to train people in the use of those products. The term screencast compares with the related term screenshot; whereas screenshot is a picture of a computer screen, a screencast is essentially a movie of the changes over time that a user sees on a computer screen, enhanced with audio narration.

There is an excellent chart available on wikipedia comparing the various software tools available for screencasting
