Abstract: An interactive networked classroom system including a teacher workstation with a base application, and one or more code segments. Each code segment includes a teacher version and a student version. The code segments include API links to a base application at the teacher workstation, or to helper functions such as plug-ins to the base application, such that the student version of the code segment has different rights, typically fewer and less powerful rights, than the teacher version of the same code segment. The teacher workstation forwards the student version of a code segment to student workstations that are in communication with the teacher workstation over a network facility; the student code segments may be embedded in a document corresponding to a classroom activity. Interactive classroom activities are then carried out using the code segments in combination with the base application.

Abstract: Various systems and methods for equation graphing are disclosed herein. For example, some embodiments of the present invention provide methods for graphing equations in a substantially real time environment. Such methods include receiving a first equation and a second equation, and parsing the equations such that they are each formatted in a common format. In addition, the first parsed equation is reduced to one or more first equation shapes that provide a graphical representation of the first equation. A determination is made abut whether a real time control has been satisfied. Where the real time control has been satisfied, the first equation shapes are painted to a display prior to reduction of the second parsed equation to one or more second equation shapes.

Abstract: A graphing calculator having a user interface that allows the user to easily specify a mathematical function. The user interface allows the user to specify a constant function, a linear function, or a non-linear function in a simplified input format. The user interface can also be implemented on devices that have limited input and output capability. An embodiment of the present invention is a graphing calculator, which allows the user to easily input a population growth rate function. The user interface of the present invention calculator helps the student to more readily adjust a function and observe the result of the adjustment. Similarly, other embodiments include the same user interface functionality in a software application package that is executed on a computer or graphing calculator.
