1. Exercise Solution Check Specification Language for Interactive Programming Learning Environments

Abstract

Automatic checking of the correctness of students' solutions of programming exercises for generating appropriate feedback is a necessary component of interactive programming learning environments. Although there are multiple ways of specifying such a check, ranging from mere string patterns to code written in general-purpose programming language, they all have their deficiencies, with the check specification being too verbose, too complicated, difficult to reuse, or very limited in its expressive capabilities. In this paper, a new language designed especially for this purpose is described. It provides both extension and replacement for RegEx-based pattern specification so that checks typical for programming exercise verification can be expressed in a concise and highly-readable manner.

Abstract

This paper describes a new XML compression scheme that offers both high compression ratios and short query response time. Its core is a fully reversible transform featuring substitution of every word in an XML document using a semi-dynamic dictionary, effective encoding of dictionary indices, as well as numbers, dates and times found in the document, and grouping data within the same structural context in individual containers. The results of conducted tests show that the proposed scheme attains compression ratios rivaling the best available algorithms, and fast compression, decompression, and query processing.

Abstract

The aim of this paper is to determine the overall student preference to learning one of two programming languages: C# or Java. We performed a questionnaire survey among students in the subject field 'computer science and econometrics' at the University of Szczecin. All students were learning both C# and Java in the same semester and with the same course leader. We investigated obtained results for each of the 13 individual questions. Then we aggregated them using the Analytic Hierarchy Process (AHP) method to express students' preferences quantitatively. The results show a very strong dominance of student preferences to learning C# (73%) rather than Java (27%). In fact, according to the respondents, the only advantage of Java is its higher value in a future professional career. We observed the strongest preference for C# in beginner part-time students, and the weakest preference for C# in beginner full-time students. [ABSTRACT FROM AUTHOR]
