There are several apps that can produce an online PowerPoint with a voice-over. In most cases a new menu tab is added to the ribbon in PowerPoint after installation. With this menu you simply click the recording button and when finished publish the result as a learning object ready to be uploaded to Absalon. In some apps you can navigate in the presentation using an outline of the slides or with buttons that control the playback and you can make a break with a quiz. Video can be added with a webcam or be imported.
What is it?
What is the value?
The presentation can be recorded on your own computer and published on e.g. Absalon as a learning object. The learning object do not need to be downloaded as it is streamed.
The students can watch the presentations whenever they want and as many times as they like. It is possible to navigate in the presentation so it is easy to continue after a break or review part of the presentation. In this way you can save valuable time to interact with and activate the students in class.
Once recorded the presentation can be reused several times maybe after updating a few slides.
An example of the use of Office Mix:
It is important to use a good microphone. It is difficult or impossible to fix bad audio quality and it’s tiring having to listen to poor quality audio.
An online presentation should be kept short, 6-12 minutes (Philip Gou, 2013). A 45 minutes lecture can then be turned into several presentations or you can break up the presentation with a quiz (applicable to some apps). The experience is that when recording you need a manuscript which on the other hand makes it easier to remember everything and to cut to the bone. At the same time there are no distractions so in most cases the presentation will be a lot shorter than done live.
It is recommendable to have a discussion or a chat in connections to the presentation giving the students the possibility to ask (and answer) questions. Especially if you do not bring it up in class. For further tips about presentations read Presentation with slides.
Putting lectures etc. online is an important part of flipped learning where they are a part of the preparation for the students who then are activated in class with various task.
Which Software Should I choose?
Several apps are available as a plugin in PowerPoint for PC. Examples are Office Mix, iSpring Presenter, Adobe Presenter, and Camtasia. Microsoft has introduced a free plugin for PowerPoint 2013/16 called Office Mix. This plugin produce a narrated video from your PowerPoints or you can upload to mix.office.com and get an embed code or a link for the presentation. You can include a webcam recording as an overlay on the slides. The next three mentioned produce a package of HTML pages and you can even add quizzes and videos. The first two are the easiest to work with. The advantage of all these apps is beside the recording that the published result can uploaded and streamed from a web server, eg. a LMS like Absalon. Alternatively you can use a free screen recorder like Screencast-O-matic to produce a mp4 video.
