3. Target group and benefits Students in first course of programming – Web based interface to follow working of programs – An automated evaluation system for evaluating assignment submissions with quick response time Teachers – Aid to teaching, both online and offline – Aid to evaluation that scales well with student numbers

4. Motivations 4  Very large cohorts of students in almost all large educational institutions or universities across the world, specifically in India ■ Intake of undergraduates is around 1000. ■ In laboratories, each student has to submit about 9 to 12 assignments and up to 3 laboratory based tests. ■ That amounts to nearly 15,000 submissions per semester.  Due to increase in number seats in the government institutions, the situation will become ever worse  Without automation, the instructor would be busy most of the time in testing and grading work at the expense of time that could be spent interacting with students ■ Quality of TA support in India still developing ■ Heavy involvement of faculty members required for quality control  Individual attention is scarce and should be of high value

5. Background  In 2002, a course management system was developed (in-house) to handle assignment display, assignment submission, assignment marking, etc.  In 2004, an elementary web based algorithm animation system was developed for teaching programming (PDS)  In 2006, a basic system for automatic evaluation of C programs was developed  Related publications have also been made in the reputed international journals and conferences  The aim of this project is to consolidate those techniques for teaching programming to a large and geographically diverse gathering of students. 5

6. Objectives  Deployment of program animation techniques to trace running of programs over the web  Development of a versatile automated evaluation techniques for C programs  Development of meta marking for graded performance evaluation  Development of library of graded problems to support stepwise learning  Extension to Java and C++ to cover basic object oriented features 6

7. Basic pedagogic mechanisms  Algorithm animation for computer aided interactive self tutoring  Incorporation of online testing into algorithm animation system  Library based approach for animation examples  Instructors may also add or modify content  Dissemination of assignments through WBCM  Automatic evaluation integrated with WBCM for interactive submission and feedback  Controlled feedback level so that automatic evaluation can be used differentially for regular class assignments and tests

8. Important issues in the proposed research  Addressing a wide spectrum of aspects of evaluation including testing, grading and feedback towards ensuring uniformity and quality  Ease-of-use for the instructors and students  Automatic evaluation should be as close to human evaluation as possible, including part marking for individual aspects of problems  Online evaluation and fast feedback to students for iterative improvement  Meta evaluation techniques monitor how efficiently the student is progressing with the assignment 8

9. Algorithm animation  Students can trace execution of programs  Web interface, special expertise not needed  Visual aid to understanding program execution and modification of data structures  Library of animations  Instructor can make additions or modifications  Incorporate meta evaluation with algorithm animation to aid fine grained assessment 9

10. Automatic evaluation  Aimed at exercising functions written by students  Assignments need tailoring for automatic evaluation  Generally avoid handling of textual output because of high variability, but ok for simple cases  Library of assignments for automatic evaluation  Instructor can make additions/modifications  Web based interface to help instructor to develop assignment statements suitable for automatic evaluation 10

11. 11 Timetable and Work Plan

12. 12 Total Budget

13. 13 Targeted deliverables  Development of open-source software packages based on the work done  Web-based methods for easy access  Publications in leading conferences in this area and reputed journals.  Dissertations of the students working in this group
