Case Studies in Science

Teachers, professors and instructional designers working in the science field are going to LOVE this resource. The State University of New York at Buffalo is maintaining a bank of Case Studies for Science. It's faily large and includes teaching notes for each case. Also, each case has an answer key that is accessible by registered instructors. It is definitely worth a look! I find this repository excellent! If you know of any other similar repositories for case studies please let us know by clicking "comments" below.

TED Talks

I've seen this referred to on a few other blogs recently and I hesitated to post it here for fear of too much duplication for the edublog surfers out there; however, after watching a few TED Talks I decided that it’s too good to pass up. This is the first I hear of the TED conference: Technology, Entertainment and Design. Six TED talks/videos have been posted online from these speakers: Al Gore, Sir Ken Robinson, Tony Robbins, Majora Carter, Hans Rosling and David Pogue. Ken Robinson’s might carry the most appeal to readers of this blog because his talk is on education; however, they are all worth taking in. So book yourself some time, maybe on your lunch hour, put your feet up and watch these talks. They are great!

Assessments in web-enabled courses

As an Instructional Designer with an interest in technology-enabled courses, colleagues have often asked me: “What type of assessments can I use in my web-enabled courses?” Of course, there is no perfect answer to this question; however, there are a couple of good places to start exploring the issue. One spot worth visiting is the Journal of Learning, Technology and Assessment. This free online journal publishes refereed articles directly on this subject. Although less than prolific, it published only eight articles in 2005, many of the articles are useful.

For example, the most recent article is entitled: Computer-Based Assessment in E-Learning: A Framework for Constructing "Intermediate Constraint" Questions and Tasks for Technology Platforms. It gives a good overview of a taxonomy of assessment types for web-enabled use. I find it useful because it gives 28 different examples that instructors can relate to. It’s not a panacea; however, it certainly functions well as a seed for ideas. Be sure to check it out and if you know any other good sources of ideas on this subject then please leave a comment by clicking the 'comments' word below.

Concept Maping using CmapTools

I attended a great talk on June 7th entitled, Using Concept Mapping and Problem-Based Learning to Encourage Meaningful Learning (presentation archived here). It was delivered as part of the TeachU series offered through the Ohio Learning Network. The presentation was by Ellen Lynch, Tracy Herrmann, and Margaret Cheatham at the University of Cincinnati.

I really enjoyed the way the way they introduced the use of their concept mapping software of choice: cmap tools. I had never used this free software before and seeing it in action in this setting really peaked my interest. So I downloaded it the next day and I tried it for myself. It really is easy to use. Ellen and Tracy describe many ways in which they used concept mapping to create meaningful learning in their students. The one way that they described that I really liked was to use two concept mapping activities as a way for students to validate their own learning. Prior to a term beginning, or prior to a unit beginning, students are asked to a create a concept map describing what they know about the subject. At the end of the term, or unit, students create a new concept map depicting what they know about the subject. In the second concept mapping exercise, Ellen, Tracy and Margaret invariably see that students demonstrate far more knowledge and that they are able to show relationships between related topics. This rings true to me. I’ve never done a concept mapping exercise as they describe; however, I have used pre- and post-testing and I have seen dramatic results. One of my interests about concept mapping is that this thoughtful, and thought provoking, activity can demonstrate relationships between concepts. It’s not simply a regurgitation of facts. Students must demonstrate higher cognitive levels of thought by analyzing, synthesizing and evaluating the knowledge they have gained during the term or unit.

Just to prove it to myself, I have made two concept maps using the cmaps tools. By the way, they neatly export into JPEG format. Nice! The first concept map would be a typical concept map created by a 1st year university student on the first day of class. The class I taught last Fall was called Fundamentals of Teaching Adults. If I were to give them a short tutorial on what concept mapping was, then give them the title of the course, and then ask them to create a concept map covering the major areas in this course they might come up with something simple like this (click to enlarge):

And at the end of the course, if they were to repeat the exercise they might create concept maps that come closer to this more complicated map (click to enlarge):

Clearly a student who can prepare a complex concept map showing how parts of the course interrelates with each other is showing understanding of the concepts. It’s an excellent post-learning activity. Another facet of this that I like a lot is that there is an element of creativity built in. It is likely that if you conducted this activity with a large class, that you would get several creative designs to the concept map. As an instructor, examining some of the concept maps created by students might just open new ways of thinking about the material for myself. That can be a wonderful side effect! I’m going to try this in the Fall term with a Chemistry course I’m teaching. I’ll be sure to report back here on how the activity went.
