2. What is a screencast? A screencast is a digital recording of the computer screen, also known as video screen capture, often including audio and sometimes including webcam video.
3. (Dis)Advantages A real DIY instrument An easy and accessible way of enriching learning materials with multimedia content It enables distance learning Student-centered in a certain way (student decides when/where) Online video can create access for non-regular student groups Online video enables possibilities of re-use. A (small) learning curve ICT knowledge Application of the medium A good screencast needs preparation and takes time to create. Good hardware is necessary (good computer, microphone, webcam) There’s a danger of ‘overstretching’ a screencast
4. Possible educational applications Offering instructional videos for ICT applications Explaining (parts of) software Explaining websites or web applications and their functions Typical: screen recording + voice over audio. Creating “mini lectures” Giving a short instruction 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. Giving/solving an assignment E.g. teacher/student takes a certain position or defends a certain statement concerning a relevant theme in a course Typical: Audio + image of teacher with additional slides/mindmaps/spreadsheets/websites/etc.
29. 1. Preparation of the environment Audio is the most important! Record the best audio you can! (try!) Use a good microphone or headset Control sounds in your direct environment Turn of air conditioning / other machines (zooming noises) Problem: noise of your own computer
30. 1. Preparation of the environment Adjust your webcam Avoid using the screen light alone Create ‘soft’ light Avoid color changes Avoid distractions in the background
31. 1. Preparation of the environment Sit in a comfortable position in front of your screen/desk Avoid bowing movements to get close to the microphone Avoid annoying mouse cords Think about where you put papers to read from. Every page turned is hearable/seeable! Avoid distractions Flickering lights of other computers? Cellphones off! Squeeking chair?
32. 2. Preparation of the content A script/scenario is very important. The best way of doing a screencast is short and to-the-point. Write down your script. It can be very detailed if you want, but at least a good structure is essential. Time: a screencast should have a maximum of about 5 minutes A combination of screencasts can form a lesson, in which one screencast builds up to the next (simple complex) Start with the essence of the screencast: Use an opening sentence like: “the following screencast is about…” Don’t spend too much time on one screen If you have to explain a more complex concept or action, use additional texts or images (afterwards, while editing the recording)
33. 3. Recording tips Before recording, do a walkthrough of all the necessary screens and software, so that everything is available Practice on switching screens! Pay attention to the your screen’s resolution A low resolution can sometimes be better, since the icons and mouse seem bigger. Try this out! If a low resolution doesn’t work, reserve enough time in the recording for zooming in afterwards during editing. Tell the viewer what he/she should be looking at Of course the mouse helps already, but you can emphasize parts of the screen, e.g. with arrows, colors, lines or audio. This is especially important when using (or explaining) keyboard shortcuts.
34. 3. Recording tips Avoid ‘visual noise’ Avoid unnecessary icons/backgrounds Avoid unnecessary open windows Turn off windows updates! Remove personal information work-related information, passwords, accounts, etc. Solution: make the screencast on another account on your computer. Control mouse movements 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. Before After
35. 4. Editing tips Split up your screencast in several parts A series of short screencasts is better than one lone one. Delete unnecessary material “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. Support what you say with text balloons or textual explanation This also increases accessibility! A transition between scenes or a filter can work quite well, but avoid an overkill of transitions Light up arrows only when relevant Only zoom in on important details
36. Distribution As a movie file upload to Youtube/Vimeo/etc. As an HTML package (with table of contents) which you can directly copy paste onto your server.
