What is a screencast?<br />A screencast is a digital recording of the computer screen, also known as video screen capture, often including audio and sometimes including webcam video.<br />
(Dis)Advantages<br />A real DIY instrument<br />An easy and accessible way of enriching learning materials with multimedia content<br />It enables distance learning<br />Student-centered in a certain way (student decides when/where)<br />Online video can create access for non-regular student groups<br />Online video enables possibilities of re-use.<br />A (small) learning curve<br />ICT knowledge<br />Application of the medium<br />A good screencast needs preparation and takes time to create.<br />Good hardware is necessary (good computer, microphone, webcam)<br />There’s a danger of ‘overstretching’ a screencast <br />
Possible educational applications <br />Offering instructional videos for ICT applications<br />Explaining (parts of) software<br />Explaining websites or web applications and their functions<br />Typical: screen recording + voice over audio.<br />Creating “mini lectures”<br />Giving a short instruction<br />E.g. a complex assignment, a difficult word, (part of) a theory, etc, could be recorded so that students can repeatedly watch it and learn at their own pace.<br />Giving/solving an assignment<br />E.g. teacher/student takes a certain position or defends a certain statement concerning a relevant theme in a course<br />Typical: Audio + image of teacher with additional slides/mindmaps/spreadsheets/websites/etc.<br />

1. Preparation of the environment<br />Audio is the most important!<br />Record the best audio you can! (try!)<br />Use a good microphone or headset<br />Control sounds in your direct environment<br />Turn of air conditioning / other machines (zooming noises)<br />Problem: noise of your own computer<br />
1. Preparation of the environment<br />Adjust your webcam<br />Avoid using the screen light alone<br />Create ‘soft’ light<br />Avoid color changes<br />Avoid distractions in the background<br />
1. Preparation of the environment<br />Sit in a comfortable position in front of your screen/desk<br />Avoid bowing movements to get close to the microphone<br />Avoid annoying mouse cords<br />Think about where you put papers to read from. Every page turned is hearable/seeable!<br />Avoid distractions<br />Flickering lights of other computers?<br />Cellphones off!<br />Squeeking chair?<br />
2. Preparation of the content<br />A script/scenario is very important. The best way of doing a screencast is short and to-the-point.<br />Write down your script. It can be very detailed if you want, but at least a good structure is essential.<br />Time: <br />a screencast should have a maximum of about 5 minutes<br />A combination of screencasts can form a lesson, in which one screencast builds up to the next (simple complex)<br />Start with the essence of the screencast:<br />Use an opening sentence like: “the following screencast is about…”<br />Don’t spend too much time on one screen<br />If you have to explain a more complex concept or action, use additional texts or images (afterwards, while editing the recording)<br />
3. Recording tips<br />Before recording, do a walkthrough of all the necessary screens and software, so that everything is available<br />Practice on switching screens!<br />Pay attention to the your screen’s resolution<br />A low resolution can sometimes be better, since the icons and mouse seem bigger. Try this out!<br />If a low resolution doesn’t work, reserve enough time in the recording for zooming in afterwards during editing.<br />Tell the viewer what he/she should be looking at<br />Of course the mouse helps already, but you can emphasize parts of the screen, e.g. with arrows, colors, lines or audio.<br />This is especially important when using (or explaining) keyboard shortcuts.<br />
3. Recording tips<br />Avoid ‘visual noise’<br />Avoid unnecessary icons/backgrounds<br />Avoid unnecessary open windows<br />Turn off windows updates! <br />Remove personal information<br />work-related information, passwords, accounts, etc.<br />Solution: make the screencast on another account on your computer.<br />Control mouse movements<br />Too many mouse movements annoy the user/viewer. Leave the mouse alone while recording unless you need it to perform an action on the screen.<br />Before<br />After<br />
4. Editing tips<br />Split up your screencast in several parts<br />A series of short screencasts is better than one lone one.<br />Delete unnecessary material<br />“Kill your darlings” and be critical! For example: if opening Microsoft Word takes a long time, it’s better to cut out the waiting time.<br />Support what you say with text balloons or textual explanation<br />This also increases accessibility! <br />A transition between scenes or a filter can work quite well, but avoid an overkill of transitions<br />Light up arrows only when relevant<br />Only zoom in on important details<br />
Distribution <br />As a movie file upload to Youtube/Vimeo/etc.<br />As an HTML package (with table of contents) which you can directly copy paste onto your server.<br />
