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. The use of scripting language (or applets) enables education personnel to create new educational contexts without requiring alteration of the base application code.

and wherein the one or more data access links in the API links for the teacher version of the first code segment are not included in the API links for the student version of the first code segment.

5. The system of claim 3, wherein a second helper function aggregates student input data;

wherein the API links for the teacher version of the first code segment comprises one or more data links to the second helper function, by way of which the teacher workstation can access the aggregated student input data;

and wherein the one or more data links to the second helper function are not included in the API links for the student version of the first code segment.

6. The system of claim 3, wherein the API links for the student version of the first code segment comprises one or more links for transmitting student-to-student communications to a first helper function;

wherein the API links for the teacher version of the first code segment comprises one or more data access links to the first helper function for accessing received student-to-student communications;

and wherein the teacher version of the first code segment includes program instructions that, when executed by the processor of the teacher workstation, causes the teacher workstation to forward the student-to-student communications to intended recipients.

7. The system of claim 6, wherein the teacher version of the first code segment includes program instructions that, when executed by the processor of the teacher workstation, causes the teacher workstation to arrange selected students into groups.

8. The system of claim 3, wherein the helper functions comprise plug-ins to the base application.

9. The system of claim 1, wherein data stored by the memory resource of the teacher workstation comprises:

a plurality of documents;

wherein each of the one or more code segments comprises a script;

wherein the base application includes program instructions that, when executed by the processor of the teacher workstation, causes the teacher workstation to;

embed a student version of a first script in a first document; and

transmit the first document with the embedded student version of the first script to one or more student workstations.

10. The system of claim 9, wherein the teacher version of the first script includes program instructions that, when executed by the processor of the teacher workstation, causes the teacher workstation to:

arrange selected students into a plurality of groups; and

transmit a document to each of a first and a second group, the documents transmitted to the first and second groups differing from one another.

11. The system of claim 1, wherein each of the one or more code segments comprises an applet comprised of a teacher version and a student version, each version of each applet comprising executable program instructions;

wherein the teacher and student versions of a first applet each includes software development kit (SDK) facilities providing access rights in the system;
