For which studies is this course planned? (Bachelor/Master)


In which field of study is the lecture located?

Visual Computing (compulsory lecture)

Type of the lecture (VO, UE, VU,...)

VU (lecture with exercise)

How many participants does this lecture have?

Around 30 people.

Is the lecture held by a team?

Yes - Clemens Müllner for the lectures and Alois Panholzer for the exercises

What tools and media do you use?

TUWEL, Zoom (together with a pdf of the textbook), YouTube

Please describe briefly the concept of the lecture.

The lectures took place via Zoom calls. The pdf of the textbook was shared there and discussed with the students. This eliminated the writing work for all participants, which in particular left more time for examples and questions. In addition, when questions arose, suitable pictures could be shown very quickly and easily (e.g. on Wikipedia). Additionally, the recordings of the lectures were uploaded to YouTube (and provided with timestamps for easier navigation).

The exercise examples were worked out by the students, uploaded via TUWEL and completely controlled. Since presenting the exercises was omitted, sample solutions were provided. At the end of the course, students were given the opportunity for a final discussion talk in order to explain their elaborations.

How do you keep communication and feedback with students active throughout the semester?

In the TUWEL-course the possibility was given to give anonymous feedback. This was started about two weeks after the changeover to distance learning, in particular to receive feedback for the new form of teaching or to obtain suggestions from the students.

In addition, there was always an opportunity to ask questions before the lecture (as well as during office hours) and direct feedback was often requested at the end of the lecture.

What kind of performance assessment is conducted for this lecture?

The performance assessment consists of two parts:

  • A written examination at the end of the lectures.
  • Exercises during the semester.

What kind of extraordinary challenges do you see in performing this lecture in distance learning?

Since this course is only offered in the Master studies (Visual Computing), the courses for Analysis 1 (on which this lecture is based) of the students are normally already several semesters behind. Therefore, it needs some time to introduce the students to this topic again.

What special positive experiences do you had?

The students' feedback was exclusively positive and a few students suggested that this form of teaching should be considered in the future as there is more time for questions and examples.

What wishes do you have to support the sustainable development of digital learning at the TU Wien?

An increase in the number of lecture halls with the possibility of using LectureTube to make more recordings of courses available to students.

Do you see your concept as an emergency solution under the current circumstances or as a sustainable extension of your teaching?

As also already suggested by some students, the originated recordings are made available in any case to the students who participate in future in this lecture course.

It is also worth considering this form of teaching - in particular for the lecture part, especially if there is not enough capacity for recording via LectureTube.

Further remarks

By giving the lectures via Zoom, the students were given the opportunity to ask questions directly or to interact with the lecturer. In addition, the recordings offer the possibility to view parts of the lecture again at any time, if parts have been too fast or initially incomprehensible.

The exercises took place exclusively via submissions, since the VU was held in a blocked manner (2 months) and thus there was very little time left after the initial changeover. Otherwise, a changeover to Zoom calls would have been considered, where the students present their elaborations of the examples (similar to "classic cruiser exercises"). This worked very well in the exercise Analysis 2 for Informatics, among others.
