EdTech 505 Blog III

This week, I delved deeper into the Evaluation Test and getting in touch with my “visual” metaphor.  The Evaluation Test was a greater challenge to learn how to create, play, and insert pictures, word.doc’s, and adding text in GoogleDocs.  My goal based plan was to learn the technology before applying my knowledge to technology.  While I had fun learning the basics of applying technology, putting together the Evaluation Test slides was a bigger challenge.  I wanted to state my purpose of why evaluation would be important to me if I were ever an educational technologist.  If I were ever an educational technologist, I would want my students to understand the basic of technology, after all…it’s better to understand the tool before applying the tool, right?  Second, using a “visual” metaphor helps learners to see before doing.  When creating a mental picture of collecting and analyzing data to determine which direction your objectives are, evaluation becomes an everyday life activity of making decisions.  Third, when evaluating efficiency, effectiveness, and impact, you have a goal in mind.  The goal would be to understand what is the need to evaluate.  Usually the goal is the end results or impact.  When collecting and analyzing data, the information will either be quantitative or qualitative.  If the test on data is consistently valid and continuous, then it is reliable.  If data was tested only to prove its desired results, then it is valid.  Validity only shows that the test or measurement has to be accurate before the outcome can be accurate.

The question that asked was what was my opinion about the use of visual metaphor to reinforce my learning.  Well, it has been said that “a picture is worth a thousand words”, seeing a picture and creating a mental activity gets the creativity juices flowing in the mind.  For instance, a magnifying glass looking at “data” creates a mental activity of what are you going to do with that data?  Are you going to evaluate it?  Are you going to research it?  The visual metaphor is a target of what you are going to learn.
