As of May 2019, this system is no longer supported, but it has a followup project Teaching genetics with dragons
(About BioLogica, retrieved 17:50, 18 August 2007 (MEST)).
- Biologica is a successor system of GenScope. “Superficially, BioLogica looks a lot like GenScope. It has the same dragon species, though we plan to add more, and many of the same levels and tools. But whereas GenScope is a general purpose tool that students can use to investigate genetic phenomena, BioLogica is a tool with which researchers and teachers can develop genetics curriculum in the form of web-labs”. (retrieved 18:44, 21 July 2006 (MEST)).
Where GenScope's interface can be described as tool-driven, BioLogica's is activity-driven.
According to the BioLogica Research page (retrieved 17:50, 18 August 2007 (MEST)), the team's basic hypothesis is that understanding biological phenomena requires learners to construct, elaborate and revise mental models of the phenomena under study. Accordingly the authors claim that “The importance of models and modeling in scientific research has been widely documented. Models are used both to describe scientific phenomena and to generate testable hypotheses. Today, models and modeling are considered essential components of scientific literacy. With the importance of models and modeling to science education comes the need for a coherent theory of model-based teaching and learning (MBTL).”
MBTL can be summarized with this picture:

Features and architecture
- Biologica runs as a model within a hypermodel, i.e. a designer must write a script to define a pedagogical scenario with educational activities.
The BioLogica system is built with three separate layers, also called engines:
- At the lowest level is the domain engine, a database plus views to display information.
- Pedagogica, as the name suggests, handles all things pedagogical. It controls the flow of activity and is in charge of all interface details like placing text boxes, buttons, tools, domain engine views on the screen.
- The scripting engine allows the curriculum developer to create a "web-lab", i.e. a usable learning environment.
Note: The global system that runs GenScope is also called Pedagogica, a bit confusing, but maybe that was decided after the above information was written ...
My Dragon Baby
Daniel K. Schneider made a dragon baby in 10 minutes (most of which was spent with downloading the software).
Of course, I didn't learn much. This is a typical simulation without teacher and teaching scenario effect. Maybe you are not totally happy with Alicia. I think she should have wings. By clicking on the + icon you could see chromosomes details .... an make a baby with wings ;)
- The system ran once over the Internet (now disabled 18:44, 21 July 2006 (MEST))
- An off-line version is available from the Concord Consortium as of August 2007. Simply download Pedagogica. It will include Biologica plus other microworlds.
