Making and using video introductions for physics lab experiments Alexander Struck, Georg Bastian Daria Dvorzhitskaia, Lina Kyvoruchkov, Lea Wemmers, Antonia Geck 2015-08-18 1
Our situation HSRW: International University of Applied Sciences • Students from many countries with different school education • Faculty of Technology & Bionics: engineering, materials science, science communication • Physics is minor subject for all BSc. programs • Wide range of motivation amongst students Big obstacle for many students: Physics labs! 2
What can go wrong ? Dropped physics early in school Don‘t like the topic Don‘t have enough time Not used to scientific Scared of math thinking 3
A typical physics lab experiment at HSRW Download instruction manual (2-4 pages), prepare theory and understand experimental setup Write a small test before the actual experiment Perform experiment (in groups of 2- 3 students), take data Analyze data, write a lab report acccording to distributed template 4
Time consumption • Mainly by writing lab reports • Difficulties often arise through lack of preparation • Workpile grows larger over the course of the semester and hampers preparation for the next experiment Naive solution attempt : „ multimedia instructions “, videos, smart phones, templates 5
Advantages of DIY video instructions: Didactical • Greater motivation to play, experiment, especially if the result is not immediately shown • Reduced fear of the apparatus • Eagerness to perform an experiment rather independent of ist role in the learning process • Enhanced fun factor, flow experience • Applied project for Science Communication students 6
Advantages of DIY video instructions: Practical • Saving teaching time especially in large groups • Small features of the experiments can be enhanced by zooming • Explanations on the real object, not on a drawing • First experience of how the experiment should look like • Time for editing the videos is shared between many, time effort of the instructors is reduced 7
Some previous attempts • Using video tapes for teaching physics (1974): http://searchworks.stanford.edu/view/873958 • Clicker-War / Audience-Response-System – feedback from students during lectures using an app: http://mytu.tu-freiberg.de/ • Cell phone use by students: http://www.unicum.de/studienzeit/rund-ums- studium/allgemein/smartphones-an-der-uni-staendige- begleiter/seite/1/ • PhyDid 1/11 (2012), „ Influence of Video instructions on motivation of pupils “ http://phydid.physik.fu-berlin.de/index.php/phydid/article/view/310 8
Why physics labs at all? • Basic science for engineering and natural sciences • Hands-on access to physical laws • Team work • First direct and intensive interaction between professors and students, mutual feedback • Introduction to scientific methods and measurements • Introduction to technical documentation and scientific word processing 9
