This work detects the difficulty levels within a set of multiplication problems and analyses the dataset on different error types as described and determined in several pedagogical surveys and investigations. Our research sheds light to the impact of each error type in simple multiplication problems and the course of error types in problem-size.

The use of common web browsers often is a precondition to fulfil the requirements of social software tools. In this publication a new perspective as well as a couple of prototypes is presented to allow a more independent solution in this

We identified 3668 different research terms from 4607 articles' titles. The visualization tool revealed the trends of contributions in the field over the years, evolution or decline of research terms, hot research terms, key researchers, leading institutions and nations across the world, evolution of countries, continents and institutions in comparison to each other. The results in this study will allow novice and experienced educators, researchers in the field of e-learning to understand what kind of different research terms exist and to identify different research patterns over the last six years in this field.

For many web-based RIAs JavaScript (JS) is the most common programming language as it is popular as a script language for browsers. While server-side programming languages have the advantages of object oriented programming paradigm, JS bases on objects with a specific object literal notation. Using design architectures such as Model View Controller (MVC) in JS reduces the code complexity and allows semi-parallel application development. It causes an easier and much less time-consuming development on further extensions of RIAs. Web-based widgets are actually RIAs. In this paper a very simple design pattern for widget development is introduced that bases on MVC design architecture. The pattern has been applied during the development phase of widgets for the Personal Learning Environment (PLE) at Graz Univ...

This work deals with the derivation of an optimal sequence of questions by comparing similar learning behaviour of users of a mathematics training application. The adaptation of the learners’ clusters to the answers of the revised optimal question sequence improves learning.

It thus makes sense for universities to investigate whether blogs can support teaching and learning. Our paper describes the installation and deployment of a blog sphere for Graz University of Technology based on the open source software ELGG and extended by us with new features that are essential for teaching and learning. This paper summarizes the first experiences that have been made ...

Sample case study demonstrates the usage of semantic modelling of the activity context using adequate domain specific ontologies and semantic technologies and visualization of such data as result of analysis of such modelled data represented in the form of Linked Data. This approach implies the easy interfacing and extensibility on machine or human level offering fast insight on statistical trends.
