This week, we created static multimedia tutorials that employ both the Multimedia Principle and the Contiguity Principle using Clarify it, a screen shot tool. Clarify it made it very easy to take screen shots & annotate the screenshots.
For this tutorial, I decided to create a tutorial on cardinal directions and vectors for introductory high school physics students. This is a topic that students often struggle with. After using Clarify it, I think that I probably should have used Clarify it for a tutorial to show students how to log on and access our grading system or some other “how to” tutorial, but I thought I would forge ahead & use it for a physics tutorial.
The learning objectives are:
After reviewing the tutorial, the student will be able to (TSWBAT):
- Identify the parts of a vector.
- Identify Cardinal Directions and Ordinal directions on a compass rose.
- Measure a vector’s direction from the two nearest cardinal directions.
- Measure a vector’s direction counter clockwise from 0 degrees (due east).
To create the tutorial, I broke the tutorial into the following steps:
- Definition of a vector
- parts or “anatomy” of a vector
- definitions of cardinal & ordinal directions
- comparing cardinal directions to Cartesian coordinates
- Examples of how to describe the vector’s direction
- Practice on how to describe the vector’s direction
The Multimedia Principle states “use images with words rather than words (text) alone. When multimedia presentations employ this principle, images help ease the cognitive load and allows learners to encode & decode in their working memory. This tutorial follows the Multimedia Principle because it uses images with word to describe the concepts.
The Contiguity Principle states that graphics/images should be close to corresponding text which helps learners to determine relationships between words and pictures. When the images and text are close together the learner can more easily put the information into working memory because there is less cognitive overload. The tutorial follows the Contiguity principle because the text is close to the parts of the image to which they relate. Additionally, the tutorial tries to avoid captions underneath the images in an effort to attempt to reduce cognitive overload. It is better to have the text next to the image so the viewer can see the image & the words to help make sense of it.
One problem that I ran into was in the export process. I created it without any problems. In fact it was an easy to use tool. The problem was when I exported the document as a PDF, there were blank spaces before the image some of the steps. I struggled trying to figure out how to fix it. (Thank you to my classmates & Dr Hall!) I went back and reduced the tutorial to one image per step which fixed the problem. One thing I did not like about the Clarify it was I could only draw straight lines, I would have liked to have drawn curving arrows to show a counter clockwise direction. However, that is a rather a small item. I think the software was easy to figure out and use.
Below is my Tutorial on vector direction.
