Chapter 5 Response

Technology can really be a benefit in the classroom when it comes to building and using models. Students can make external models using Mindtools such as, concept maps, spreadsheets, microworlds, discussion boards, and visualization to connect students learning.

Modeling knowledge with concept maps is a great idea in the classroom. I will be able to use computer based tools and programs such as Stella, VenSim, and PowerSim to help learners build simulations of a system. These are greatly effective when the simulation involves components that have an effect on other components in the system. A great example of this is the human body and the food chain. If one component of the simulation were to change it would in turn have an affect on the other components in the system. Marissa showed use a simulation with the exact purpose involving wolves, rabbits, and grass. As a side note, I probably would not use Stella in an elementary classroom. Having students create their own concept map simulations is a great tool to implement because it creates a meaningful learning experience. I believe that the real world examples such a the rabbit, wolf, and grass will help students visualize that each component depends on another and that with one change others will follow as a result. Spreadsheets main purpose is to store, calculate, and present information. Spreadsheets are a great example of a Mindtool that reorganizes mental functioning. This would be great to use in the classroom after students have already been taught how to do the calculations themselves. It would save time and energy and allow students to see a larger picture of understanding instead of just the calculations to get through the big picture.

Expert systems are systems that are designed to make decisions for all sorts of problems. An example of this is MYCIN which helps diagnose bacteria infections. This system works like any real expert would - it analyzes the expert information it has and comes to a conclusion that best solves the question. When students engage themselves into becoming an expert on a topic it ususally includes deeper level thinking. In my classroom I might use this to get students to achieve this deeper level thinking and to reflect on their models.

One thing that I will definatly be utilyzing in my classroom is a database. Databases will help me keep track of my students records, my lesson plans, and other information. Databases will help me stay organized virtually and spaticialy. My students will likewise learn how to effectivly use databases to keep track of information and different subjects. One subject it may be nice to utilize a database in would be writing. My students could write pieces and have them all under the umbrella "writing." My students would then have their pieces under non-fction or fiction and then listed by date so that the students can see the progress they have made throughout writing.

Using technology based models in classrooms keep students engaged in learning. Student engagement is a fundamental aspect of learning that I want all of my students to have. Students are engaged because they are cognitivly constructing their own theories; making their own representations of a system; going through a system of hypothesis, testing, inferring, etc.; constructing the model; and motivation of learning.
