Aus Interesse habe ich die beiden Zertifizierungen CompTIA A+ sowie CompTIA Cloud Essentials abgelegt. Insbesondere die CompTIA A+ Zeritfizierung finde ich für Personen interessant, die Ihre grundlegenden IT Support Kenntnisse in Form einer Zertifizierung nachweisen wollen.

EDULEARN14 – the human body in the virtual world – a missing part of a perfect online learning communication

Autor / Paper

The body and the behavior/movement of the partners within a communication are important in all kinds of communication. Body language is vital for lecturers to gather information about the current level of attentiveness of the audience.

Voice and text communication are the main techniques used in online learning environments. Webcams or other technical equipment used to show the users directly are not very often used, mainly because of the lack of bandwidth and the fact that the lecturer is not able to monitor all the attendees within the course. These problems also occur at other fields of online communication like gaming.

The usage of avatars – visualizations of the users – is not new, the usage of this static pictures or virtual corpses as representatives for the users is very common in the field of gaming, especially in online gaming. These avatars are mainly used to give an impression how the users connected to the username look like, or want to look like. Typically there is a big difference in the appearance of the avatar and the real user. Some users change genders, age, body measurements or hairstyle, it is also possible that users can use cartoonized images of an uploaded photo of themselves as avatars.
Synchronous online – or distance – learning scenarios, where the lecturer and the students attend the same online room at the same time suffer from two main problems. Lack of direct non-verbal feedback from the students and the lack of responsive avatars.
The first problem could theoretically be solved by using webcams, so the lecturer would get direct visual feedback of the level of attendance of the students. In practice this is not easy to handle because the lecturer would have to view the video streams of all the students while educating, in classes with docents of students this is simply not possible.
The second problem is kind of a technical, high end scanning equipment would have to be used by every student, to scan their faces permanently, so the avatars used could be responsive and give the lecturer an impression about the current mental state of the student.

This paper shows the problems, lecturers are facing when giving synchronous online lessons. The first we recognized the importance of the body in the communication and as follows also in the virtual online communication. Second we identify the difficulty to virtualize the human body. So we need to think about new methods to find a comfortable way to digitize parts of the human body language to transform these parts into a visualization. But why we need a visualization of the human body language?

Let’s think about a standard class room at the university or at school. The lecturer is able to see all participants and take care about the current reactions, e.g. yawning, be curious or digressing, during the lecture. At online class room the lecturer has no possiblity to see those reactions, feelings or moods of the participants. The only common reactions is silence of the virtual world.

Hochschuldidaktische Weiterbildung

Ich absolvierte die Hochschuldidaktische Weiterbildung an der FH JOANNEUM im Ausmaß von 2 Semester. Durch intensive Workshop-Tage, Distance Learning Einheiten sowie durch Hospitation fremden Unterrichts und des eigenen Unterrichts war es mir möglich meine Kenntnisse in der Hochschuldidaktik weiter zu vertiefen.

Weitere Bestandteile der Hochschuldidaktischen Weiterbildung waren unter anderem Unterrichtsplanung, Unterrichtsgestaltung, praktische Übungen zu verschiedenen Lern- und Unterrichtsmethoden sowie auch der breite Erfahrungsaustausch zwischen den KollegInnen.

ICEEE13 – Automatic test-based assignment and subsequent automatic assessment in e-Learning an empirical study of two courses (part-time and full-time course)

Autor / Paper

The field of eLearning and distance education is very complex and technology is changing very fast.

To keep up with new technologies, we are permanently developing new tools and evaluating new possibilities to improve our courses. Our students are provided with our own e-Learning platform called eNcephalon. Since summer term 2013, our newest feature, an automated test-based assessment module is tested at the parttime study degree program “Software Design”.

As the main features have been tested the term before under laboratory conditions, the field test proved the expected results and furthermore identified some issues which were not recognized during the lab tests.

This paper describes a field test during the lecture “Configuration-management” and the improvements for both, students and lecturers.

ICL12 – eLearning in the Cloud – benefits, costs and reasons for a cloud migration

Autor / Paper

The topic elearning – especially when combined with cloud computing and scalability – is a wide spread area which covers different research fields.

The department of Internet Technology at the FH JOANNEUM has a huge expertise in developing and using elearning systems since 2004. In that year, the department started their first online courses at one of their degree programmes.

Today, distance learning is used at two bachelor degree programmes and two master degree programmes.

While the number of students using the elearning platform has increased from 200 users to more than 2000 users over the last eight years while the server hardware has only been replaced at malfunctions and the usage of more performant hardware (except storage and memory) was hardly necessary.

This paper shows that the usage of cloud based server environments instead of self-hosted servers can help to reduce costs and the scalability helps to improve the performance.

While conventional lectures are held between monday and thursday, most of the online courses are held on friday and saturday which can also be seen at the performance logs of the elearning servers.

ICCHP12 – NAVCOM – WLAN Communication between Public Transport Vehicles and Smart Phones to Support Visually Impaired and Blind People

Co-Autor / Paper

Visually impaired and blind people want to move or travel on their own but they depend on public transport systems. This is sometimes challenging. Some problems are to find the right vehicle, signalling their wish to enter or leave the vehicle and getting information of the upcoming stations. To solve these problem very specialized equipment was develop. In this paper we show a solution with standard WLAN components and a standard smart phone, that might solve these problems. Hopefully this raises the life quality for the people with special needs.
