This document describes the need of training tools for radar image interpreters. Concepts, methods and solutions for supporting technology based training are presented and demonstrated by means of two examples: SAR-Tutor is a computer based training software for learning the basic principles of radar image interpretation. ViSAR is a simulator for exploring and understanding geometrical effects which occur in radar images. The interaction of these two tools and their use in operational training scenarios are explained

In our work we describe an approach for the automatic evaluation of student test results by a web based e-learning application, which considers more criteria than the obvious correctness. This evaluation is focused on the use in adaptive learning paths, meaning that the student's learning path is adapted based on the test results. We describe a concept which integrates the evaluation of more criteria than correctness and how an implementation of such adaptive learning paths could look like in a web based e-learning environment. Our work shows a working prototype which uses the enhanced criteria speed and certainty based upon an evaluation with fuzzy logic algorithms. Finally we present some first results about the acceptance of web based adaptive learning paths

In our work we describe an approach for automated and approximate evaluation of character based answers in computer-based tests. Cloze exercises ('fill-in-the-blank') are error-prone to a variety of potential error sources and are subject to syntactic and semantic ambiguities. Our approach combines string similarity measurements with semantic word analysis to render this type of computer-based exercise more robust and user-friendly. We present a working prototype for a web-based e-learning system supporting spelling correction (syntax level) and an extension to synonyms (semantic level). A community-based approach using OpenThesuarus.org is proposed to gather and evolve missing synonyms for given answers of cloze exercises. e-learning, assessment, cloze exercise, semantic web, open thesaurus, web service I.
