Improved Study Results with Advanced Teaching Environment

Chalkboard pedagogy is still going strong within higher education. It makes students clear how reasoning takes place instead of just presenting facts. The instructor simultaneously produce and write arguments in successive order on the board while thinking aloud. This it to visualise the reasoning, students see the process and structure of the step-by-step arguments to recognise patterns and interconnections. At the same time such talking-writing pedagogy loses connection with the contemporary but pressing movement of Open & Online education practices. The direct consequence of online practices is that all is becoming digital. Also the chalkboard should be digitised to build a bridge between campus classes, blended settings and online practices.

In 2012 an advanced teaching system was introduced combining virtual chalk and four parallel video signals, see earlier post on this weblog on April 17, 2014 ‘Advanced Teaching with Virtual Chalk and Four Parallel Video Signals’.

A few pictures to illustrate digital writing in its practice 🙂


Students and instructors were extremely positive, but had their opinions led to better study performances? Now, four years after initiation, study results of three full academic years were analysed and have been delivering interesting results. If we compare our findings with the largest and most comprehensive meta-analysis about undergraduate STEM education [1], which questions the traditional lecturing practice, we have found very competing figures. Although four-quadrant pedagogy is new, it still belongs to what is named lecture setting. How interesting would it be when active elements are added to the four-quadrant pedagogy. Read this paper and be astounded.

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.

FourQuadrantsStill   FourQuadrantsPractice

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.
