Research on automatic scoring for Java programming questions

Abstract

Automatic scoring for Java programming questions is a very important and hard problem. Currently automatic scoring technology is mainly based on whether the program runs properly. This way is not always feasible because many programs can not be executed normally only for a few errors. In this paper, an integrated method based on weight, credibility and tree structure is proposed. In this method, source file, class file, method information, output result and source code are all checked and scored with different weights. Especially for the source code, a tree-based thought is put forward. This method constructs a reasonable flow to score a Java program question. As a result, a final score is calculated successfully. The test results show this method is feasible and effective. © 2012 Springer-Verlag GmbH.
