Students, tutors, and lecturers collaborate online. The exercises together with meta data are stored in a searchable data base for reuse by students and lecturers. Problem solving is assisted by (tele-) tutors. Users input mathematical text via digitising tablets. This input is stored in the data base and it documents the process of solving mathematical problems. By this mobile CSCW support the project teleVISE aims at shifting the focus from calculation to modeling real life problems. teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌1.

In the Department of Electrical and Electronic Engineering and Computer Science, we started the project teleVISE http:/www.teleVISE.hs-bremen.de short for Tutorial Enhancement of Learning Environments: Virtual Exercises and Student Expertise to improve education mathematics. In this project, colleagues from several departments are attacking this complex problem from different angles:teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌 The mathematical content is modularised and tailored to the needs of other disciplines taught in the corresponding degree course (in english rmatik.uni-leipzig.de/theo/cps/index_2.htm and more up to date in german rmatik.uni-leipzig.de/theo/lpv/pgs/dt/Verbund/index.html). teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌 The didactical impetus in lectures, exercises, and exams favours modeling and disfavours mechanical calculations.

Working together in groups may take place face to face or online. A tight synchronisation between lecturer, tutors and students is maintained by a high degree of communication and feedback to make responses on all levels of the project as prompt as possible. As the project evolves evaluation produces additional valuable feedback for optimisation. teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌Technical provisions let people work together anytime anywhere. teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌 A technical infrastructure has been set up consisting of teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌 notebooks and digitising tablets for lecturers, tutors, and students, teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌 a data base of exercises with web interface, teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌 a data base of documents generated by collaboratively working on exercises with web interface integrating the digitising tablets teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌Notebooks, wireless LAN, and server based web applications guarantee a high degree of flexibility and mobility. teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌The paper is organised as follows. In this section we introduce our university, its learning platform and the state of the education in mathematics. This lays the ground and describes the context for the three aspects of the project teleVISE, namely didactics, organisation, and technical infrastructure we discuss in the next section. In the conclusion we describe our experiences gained in the first half of the project, indicate the next steps in the second half and give future prospects of computer assisted learning at Hochschule Bremen. teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌1.1 The University teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌Hochschule Bremen http:/www.hs-bremen.de is a University of Applied Sciences with some 8000 students studying in some 40 degree courses in nine departments one of which is the Department of Electrical and Electronic Engineering and Computer Science.teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌In 2002 Hochschule Bremen introduced (Wilkens, 2003) a university-wide learning platform http/AULIS.hs-bremen.de as a portal for all learning units in each degree course in every department. AULIS offers descriptions of all courses taught at Hochschule Bremen together with links to learning materials available on very many various servers. AULIS manages learning units, standardised by different institutions as so called learning objects modules (for an overview see e.g. (Risse, 2002), for a critic see (Dodani, 2002) , learners, i.e. (groups of) students, authors, i.e. lecturers and members of staff, and other (groups of) people with specific access rights, e.g. tutors. AULIS also provides e-mail, news groups, etc. In effect, AULIS is the one portal for students and staff of Hochschule Bremen alike: students easily find all learning materials provided by AULIS or via link on other servers run at Hochschule Bremen. Professors make their materials available to their students and can use the very simple authoring environment of ILIAS www.ilias.uni-koeln.de, the open source technical base of AULIS. teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌1.2 The Education in Mathematics at Hochschule Bremen teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌Even though education in mathematics at the different technical departments of Hochschule Bremen is rather heterogeneous all colleagues agree to strive to lay sound fundaments when teaching mathematics in degree courses like teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌 computer science, i.e. teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌 technical informatics, teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education not only in Mathematics Thomas Risse, Barbara Grter, Jrn Loviscach, Heide-Rose Vatterrott, Ulrike Wilkens Department of Electrical and Electronic Engineering and 麦汽掳镣污队林共景琳团谋宪宿第是险短袋窥署瘤抠侍孕柔刘晶灸奉秒疆砧昔狸才衔吁仲喜状诬褒罪珐虫显买募周谚铂恋赠疤撮渠押便蝶向叹丝嵌 media informatics, and teleVISEa Collaborative Environment to Improve Education not only in MathematicsteleVISE a Collaborative Environment to Improve Education no
