Gizmo – Orchestrating Multiple Research Strategies

Gizmo – Orchestrating Multiple Research Strategies

In this version of Gizmo, we have collected all three strategies (recording activity, inhibiting components, and stimulating components) together, and allow you to orchestrate the strategies to figure out the mechanism:

The third common strategy in modeling a phenomenon is to stimulate the components directly. In this version of Gizmo, we provide a device (the lightening bolt) to allow for this strategy.

Gizmo – Inhibiting Components

A common second strategy in modeling a phenomenon is to inhibit (or 'lesion') the activity of the components. In this version of Gizmo, we provide a device (the scalpel) to allow for this strategy.

An important first step in modeling a phenomenon is recording the activity of the components. In this version of Gizmo, we provide a recording device (the magnifying glass) to allow this step.

'Gizmo' is a tool developed by Peter Bradley (McDaniel College) from an original design by William Bechtel (UCSD) to teach modeling as an investigating strategy in science. This is simplest interactive version of gizmo: it has three inputs (the three buttons in the upper right) and three behavioral 'outputs': legs wiggle, tail moves, antenna move.

Flash-based interactive example of Venn diagram-enhanced categorical reasoning. This one is of A-type (Universal Affirmative) Obversion. Does ‘All cats are felines’ imply ‘No cats are Non-felines’?
