Automated Grading system for computer Programming Courses
Dr. S. Kanmani Professor and Head Dept. of Information Technology Pondicherry Engg. College Puducherry –
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

Purchase of high end Server, nodes/ hiring the services/Software and tools and equipments * 1,50,00,000 Total A+B+C 1,98,00,000
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
