... The platforms operate on the principle of strict separation between the representation of mathematical knowledge from pedagogic forms of presentation and principles of multimedia-based functionalities. The Mumie platform (Dahlmann et al., 2005b; Dahlmann et al., 2003 ) focuses on the interactivity and multimediality of the granules of content as well as their usability in multiple, diverse learning scenarios: Mathematical objects are flexibly combined by a CourseCreator into individual teaching units and presented in an explorationoriented environment (content scenario). The presentation of content on the one hand is complemented by practice scenarios and virtual laboratories supporting the individual and independent approach to mathematical content on the other hand. ...

... Then again, MathForum only supports ASCII-based circumscriptions of mathematical formulae, i.e. x^2 for x 2 etc. Thus, the specific requirements for cooperative knowledge spaces for mathematics and natural sciences [7] are not – or only rudimentally – supported by the systems presented in this section. This is probably the main reason for why there are still no satisfactory developments promoting community building and virtual cooperation in those disciplines. ...

... In many organizations, the collaborative work knows a new era (e.g. [14] [15] [16]). However, in the educational sector, this practice between educators has a long way to go. ...

... Having " built " the room, the user can determine which users or groups are to have access to it. Access, interaction rights and general key rights are regulated via a key management system [3]. ...

... Focusing on the social skills like communication, coordination and cooperation as nowadays' important factors in education, collaborative software applications possess a high potential to support the learning, teaching and research processes at university by the means of the new media and new technologies [4] [5]. As a part of the GALILEA project, introduced at the Technische Universität Berlin, the new gender sensitive Bachelor of Science program " Natural Sciences in the Information Society " [6] [7] [8] provides two new innovative lectures, which started in winter term 07/08 and summer term 2008, respectively: ...

... In order to achieve efficient e-learning in mathematics, an adapted software and well-known learning concepts and theories are required so that the right mathematical content to satisfy the learners' needs and the teachers' overall intentions is created. Among the identified mathematics e-learning platforms, the Mumie toolkit [7], is an example of a free platform for mathematics and computer science education and teaching for higher education that integrates students, lectures and tutors. Another example is the platform Assessment and Learning in Knowledge Spaces (ALEKS) [6], a payed web-based assessment and learning system based on machine learning; ALEKS uses interactive quizzes to quickly and carefully determine what a student understands and does not understand in a course. ...

... The authors of this paper are currently developing a cooperative knowledge space for mathematics, natural sciences and engineering. The ViCToR-Spaces (Virtual Cooperation in Teaching and Research for Mathematics, Natural Sciences and Engineering) [4] [3] are built on top of the existing CSCW (computer-supported cooperative work) platform CURE [10] which follows a general room metaphor known from multi-user dungeons (MUDs) or massively multiplayer online role-playing games (MMORPGs). ViCToR-Spaces focus on networking students as well as researchers of the technical disciplines, providing in particular virtual laboratories, remote experiments and rooms for team work. ...

... physical effects or machines. Also a virtual lab can demonstrate effects in a " purer " form, enhancing the results or eliminating interference that would " bury " the effect in a real experiment [3]. In contrast, remote laboratories are physically existing experiments that can be remotely controlled from any place in the world via internet. ...

... The remote control type experiments can run experiments by interacting with real devices from outside the laboratory [11]. Three experiments of hydrodynamic sliding bearing, mechanism motion analysis and multi-belt transmission test in laboratory are based on computer-controlled experimental devices, so these experiments present are further developed a program to allow control over experiment via the internet. ...

... As pointed out in our earlier work [6][7], integrating virtual and remote laboratories into a cooperation infrastructure is a core part of our project ( " ViCToR-Spaces " ). The concept of virtual cooperative knowledge spaces is derived from MUDs (Multi-User Dungeons) and MOOs (Multi-User Object-Oriented Environments) [8] online role-playing games which usually are text-based and in which tasks have to be solved cooperatively. ...
