  • Secure computer-implemented execution and evaluation of programming assignments for on demand courses
    Patent number: 11749135
    Abstract: A computer system includes a course repository and a server. The course repository includes a video of an online course, an instructor provided output for a programming assignment associated with the online course, and a submission script for generating student provided output for the programming assignment. The server includes a submission module that receives and verifies the student provided output for the programming assignment. The server further includes one or more built-in grader applications that compare the student provided output with the instructor provided output to determine a grade for the programming assignment.
    Type: Grant

  • Secure computer-implemented execution and evaluation of programming assignments for on demand courses
    Patent number: 10229612
    Abstract: In one general aspect, a computer-implemented method can include receiving, by a computer system, code for a custom grader application, creating, by the computer system, a base custom grader container including the code for the custom grader application, associating the base custom grader container with an online course included in a repository included in the computer system, evaluating, by the computer system, the base custom grader container by executing the custom grader application in the base custom grader container, determining that the custom grader application violates a predetermined criterion, modifying the base custom grader container to prevent the executing of the custom grader application from violating the predetermined criterion, and storing, in the repository and in association with the online course, the modified base custom grader container including the custom grader application as a custom grader container image.
