A step-by-step demonstration of dissecting a cow?s eye that could be used as a teaching strategy model.
Type of Material:
The Cow?s Eye Dissection learning can be done with a basic browser but requires RealAudio to extend to audio and a PDF viewer to print out the instructions. The Cow?s Eye Primer may be used on Mac or Windows 3.1 only. RealAudio Player, Adobe Acrobat Reader 3.0, & Quicktime 2.0 or better are needed for full functioning.
Identify Major Learning Goals:
Learning goal for preservice teachers in science method classes: Preservice teachers to view the learning activity as a model for developing and presenting a successful hands-on activity using a science topic.
Target Student Population:
Preservice teachers in science method classes
Prerequisite Knowledge or Skills:
Dissection of a real animal (perhaps in in previous courses)
The demonstration is a real life situation that also includes students. Each written step has the possibility of added audio that gives details of facts about eyes and the dissecting process. The glossary words are hyperlinked in the written steps to their definitions.
The images are quite small and require direct knowledge of a cow's eye to relate what the demonstrator is doing. A more current best practice would be a narrated movie
Potential Effectiveness as a Teaching Tool
The dissecting demonstration is an excellent example to use as a model for a hands-on activity. This learning activity includes hints, tips, and a glossary of terms.
It is a series of still images and lacks the actual dissection process. Given that constraint it is a useful activity.
Ease of Use for Both Students and Faculty
The learning activity has some features for both platforms, Macintosh and Windows. This learning activity is easy to use if the computer has the necessary plug-ins: RealAudio Player, Adobe Acrobat Reader 3.0, & Quicktime 2.0 or Better.
The Cow?s Eye Primer version does not run on Windows 95, as noted in the information and directions on this site.
