Computerized system and method for visually based education
First Claim
1. A computer-based educational system, the system comprising:
- a computer and a display device enabling generation of graphical objects by a user, which are displayed on the display device, in which parameters of the graphical objects are defined in terms of variables or expressions, including the variables, wherein the parameters include a size and a position of the graphical objects;
a user input device for providing inputs of values for the variables by the user, and the computer and display device updating the graphical objects in response to the values;
a library of defined graphical objects stored in the computer, which are selected and instantiated by a user to generate the graphical objects, which are displayed; and
a graphical variable controller displayed in the display device and to which the variables are associated, enabling user assignment of values to the variables by manipulating the graphical variable controller using the user input device to increment or decrement the values by a step value.

Abstract
A computer-based educational system provides the user or instructor with a suite of graphic editing tools, allowing the design of graphical objects, such as symbols and text that can be displayed to a viewer, such as a student, using a projector or computer terminal. In order to facilitate the educational process, the invention provides the user with robust ability to control parameters of the graphical objects, allowing the user to create simulations or models of subject matter, such as mathematical principles, in order to facilitate the educational process. In the preferred embodiment, the parameters of these graphical objects can actually be defined in terms of variables and specifically functions or expressions including those variables and then the values of the variables controlled in real-time by the user. This ability allows the user to control the execution of the simulations or models, enabling the user or instructor to dovetail the execution of those simulations with the instructional process.

7. A computer-based instructional method, comprising:
-
providing a library of defined graphical objects; using the defined graphical objects when constructing graphical objects, which are displayed on a display device, to illustrate principles for education of students by defining parameters of the graphical objects in terms of variables or expressions, including the variables; displaying the graphical objects on the display device to students while inputting values for the variables; and updating the graphical objects displayed on the display device, including a size or position of the graphical objects, in response to the values to thereby demonstrate the principles using a graphical variable controller, which is also displayed on the display device, to which the variables are associated, by manipulating the graphical variable controller using a user input device to increment or decrement the values by a step value. - View Dependent Claims (8, 9, 10, 11, 12, 13)
