Investigators @RILL: Sarah Hofer, Zoya Kozlova

Collaborators:

  • ETH Zurich (Andreas Vaterlaus, Andreas Lichtenberger, Barbara Gränz, Roman Schmid, Bermann Steinmacher, Peter Edelsbrunner, Ralph Schumacher, Elsbeth Stern)
  • LMU Munich (Jochen Kuhn, Stefan Küchemann, Christoph Hoyer, Max Warkentin)
  • Saarland University (Roland Brünken, Sarah Malone, Kristin Altmeyer)

Duration: October 2023 until September 2026

Funding: DFG and SNF

Main Goals: We aim to exploit the potential of Augmented Reality (AR) to successfully create an optimised learning environment that combines MER and guided experimentation.

Key Methods: The four studies investigate which AR-supported external representations are best suited to facilitate learning. We also examine how the MER interact with various degrees of guidance during experimentation.

  • Study 1 investigates which MERs best support conceptual knowledge during experimentation with high levels of guidance when it comes to identifying the direction of the Lorentz force.
  • Studies 2.1. and 2.2. focus on the comprehension of the magnitude of the Lorentz force. Study 2.1 varies the type of MER, and Study 2.2 examines how the combinations of AR-induced representations found to be best interact with the amount of experimental guidance.
  • Study 3 will apply the findings from the first three laboratory studies to the classroom to test the best combination of conditions in a field study

Practical Relevance: We expect to gain insights into how AR technology can create new learning environments in science education or enhance the existing ones.
