Advanced Teaching with Virtual Chalk and Four Parallel Video Signals

At Delft University of Technology a pilot scheme has been launched in April 2012 to introduce more advanced technological tools for teaching mathematics and other technical-scientific subjects. A virtual chalkboard was integrated with an Audio-Visual Information Technology (AV-IT) facility to present four video signals simultaneously. These video signals are for example PowerPoint, virtual chalkboard instances, PDF documents, Internet Explorer or video clips. Students watch all video signals at once to get a comprehensive overview of the method being taught.

In spring 2013 I have presented the paper “Advanced Teaching with Four Parallel Video Signals” at the 7th International Technology, Education and Development Conference in Valencia in Spain. It was based on early experiences.
Meanwhile a total of eight evaluation periods have been taken place. Hence I have been revising and expanding the paper, which describes the collected results of 457 completed questionnaires and 238 students’ comments.

Both lecturers and students are enthusiastic and prefer the SMARTboard with four quadrants over the old-fashioned chalkboard. Such encourages us to provide more lecture halls with a similar system.
