2. Automated Grading system for computer Programming Courses
An automated system to test and evaluate marks for the students’ programs developed in different programming language courses

3. Objectives
To automatically grade the students’ program developed in the programming courses taught in graduate level
To increase consistency and correctness in the evaluation methodology
To ease the overload and strain caused by the repeated work for teachers
To enable Online submission of Programming exercises

4. Scope Tutoring system for programming languages
Online certification programs
Virtual Universities
Training Institutions

5. Feasibility - Dynamic Testing
Number of testing methods exist for commercial software products
- Dynamic Testing
- Static Testing
- Program Matching
Number of testing tools exist for commercial software products
- Insure++, Jcover, Junit
- WinRunner, Test Architect

6. Feasibility
Automation accounts many features in addition to testing of programs for correctness
- Program Robustness
- Program Complexity
- Programming Style
- Program understandability
- Use of appropriate constructs

7. List of courses to be considered
C Programming language (Basic level)
C Programming language (Advanced level)
Data Structures using C language
Data Structures using C++
C++ Programming language (basic level)
C++ Programming language (Advanced level)
C# Programming language
JAVA Programming language (Basic Level)
JAVA Programming language (Advanced level)
Algorithms lab

8. International Development
Attempts made in automatic grading at
University of Bristol, U.K
University of Nottingham
Heriot Watt University
They developed the system for a specific
language/course or for a set of fixed exercises
But no such system is in practise In national level

9. Methodology
Identify a minimum of twenty exercises for each course covering the syllabus
Develop the repository of model programs for each of the exercises
Identify the best suitable test method/s and tools to used / developed for the chosen programming language
Develop the environment to collect the quantitative attributes (metrics) and pre set the expected values for grading
Accept the test program, assess the attributes and allocate marks
Apply measures to control copying

10. Timeframe For one course Analysis & case study 3 weeks
System Design weeks
System Development weeks
Test data generation and testing weeks
Integration & Performance analysis weeks
Total weeks per language/Course

13. Work Done
A pilot study was made to implement the proposed system for C programming language course offered for I year B.Tech students with 10 programming exercises
The performance of the system was compared with that of the manual system using 100 program samples
