Working definition: correlation
My points for creating this page are as follows:
- To show how I actually managed the definition thing that I promised.
First of all I wanted to share with other teachers how I tried (successfully I believe) to create a notion in students' heads of the concept of correlation. Just look at the PowerPoint-turned-to-Flash presentation below, play it (you can operate it by clicking too), read my Notes and think about it. Note that by clicking on the button in the upper right corner , you get full screen view. (The original Hungarian version of the mini presentation is taken from a large one that you can find here. I created it for Hungarian chemistry/physics teachers who visit my collections of science animations and simulations or attend my occasional lectures on the topic.)
- Embedding Flash into PowerPoint (makes sense).
Even if you are not interested in statistics, you may arrive at the same conclusion as I did, namely, that it can be a good idea to embed a Flash into a PowerPoint presentation (see slide 3). Why do I think so? Because being able to assign meaningful quantities (abundances) to the axes of the simulation I was able to make correlation less frightening or maybe even quite interesting to BSc students. On the other hand, the interactivity of the simulation adds life to the graph shown in slide 2.
Technical: You can insert a Flash into a PP presentation in no time using either the free iSpring Free software or its bigger brother iSpring Pro. (They add a tab each to the PP when you install any of them.)
- Converting PowerPoint to Flash (makes sense 2 :).
As you must have realized, what you see below is not a PowerPoint, but a Flash that was created from a PP. It means that the quality is a little poorer, but at least you can look at it while you are reading this, whereas if I had left it as a pptx or ppsx or ppt or pps file, you should have downloaded it and opened it if you dared to do so and if you had PowerPoint to begin with.
Technical: You can convert most PPs to a single swf file with iSpring Free. (It also creates an html page embedding the Flash and the only thing you have to do is double click on it and off it goes.) If for some reason the Free version fails to convert a PP correctly in which a Flash is embedded (like in the present case), iSpring Pro will do it for you. It also adds both fancy and useful things to the presentation. Open the References tab for instance. The first two links open two different converted versions of the same PP which you see converted below. One is the Free type, and the other is pure HTML 5 (a possible future of animations) produced by iSpring Converter. (For more detail see this1, this2 and this3 page of mine.)
