Have you heard of “death by PowerPoint”? I am sure many of us have sat through a professional development session (or maybe a few) where the lecturer (sage on the stage) thought the most efficient way to promulgate their wealth of knowledge was via a PowerPoint presentation. They probably had way too much text on the screen and read most of the text from the screen. PowerPoint was never designed to be used like this. “Less is more” is certainly true when it comes to PowerPoint presentations. PowerPoint was designed to be a visual clue for the presenter to keep on task and also to provide a scaffold for the learner via minimal text on the screen. If in doubt, have a look at most of the presenters at TED Talks.

How many of us are guilty of inflicting “death by PowerPoint” on our students? At the end of the unit of work on multiculturalism, for example, how many of us have asked for the obligatory PowerPoint presentation for the student to demonstrate their knowledge? Don’t get me wrong, an end of the unit presentation is sometimes the best way to demonstrate knowledge … sometimes! In contemporary schools, there are a plethora of ways children can demonstrate their learning, especially using technology. However, that is the scope for another blog one day!
At the end of a unit of work, apart from all the formative assessment learning activities the students have been involved in, there may be a justifiable reason for a summative assessment such as a culminating activity. No, I am not going to suggest a PowerPoint presentation here! A summative assessment, as the name implies, is an “at end of work” or “summary” of their learning. It could be as simple as the “Learn” column on a KWL chart, or as comprehensive as a website the student has created or a performance through the Arts.
Closely aligned with my previous blogs on the “so what of learning” and a “call to action”, I propose we should consider a “performance of worth”. When designing the unit of work sometimes teachers work backwards and plan from the performance of work (summative assessment activity) through all the learning activities required back to the initial learning activity to pique interest and assess prior knowledge.

If you decide a summative assessment is warranted then let us consider what might be a performance of worth. The performance of worth is a double-edged sword. It has “worth” because it is, generally, an important assessment piece to gauge student learning. Secondly, it is of “worth” to the student as they demonstrate their learning. For example, if you have been studying basic electrical circuits in Science, you could give the children a worksheet where they have to identify circuits that would work or not work. Even better, you could ask them to use an app such as Explain Everything and explain why some circuits would not work and how to make them work. Even better and more engaging would be for the student to make a house with lights and alarms that are activated by pressure pads (aluminium strips to connect the circuit). The students would not only demonstrate their knowledge, but also the application of the knowledge which s a higher-order skill (Bloom’s taxonomy). See for example https://www.instructables.com/Electronic-Cardboard-House/
Again, I have nothing against PowerPoint, is used correctly, however, there are far more engaging and higher-order performances students can utilise to demonstrate their learning.
