STUDENT-CREATED VISUAL SIMULATIONS IN PHYSICS Madelen Bodin Department of Physics, Umeå University. e.mail: madelen.bodin@physics.umu.se Supervisor: Sune Pettersson, Sylvia Benckert. The aim of the work is to investigate how computers can be used as a cognitive tool in a problem solving situation in university physics by letting the students create their own simulations and 3D-visualisations of real-time physical situations. The research questions concerns what the students actually are learning and how. Do they get a deeper conceptual understanding or do they just become even more skilled in manipulating equations and computer code? What is the importance of the prior knowledge of the students when it comes to programming or physics? Does this approach of active learning help to develop the chains of association in physics problem solving? How do they learn to control the knowledge they have acquired? The main part of being an expert in physics is the ability to solve problems. This ability means to be able to model physical systems by combining physics concepts with tools such as mathematics. The main difference between an expert and a novice in problem-solving is how the problem is modelled. Where the expert sees a pattern of concepts and tools the novice is only able to see isolated concepts and equations. By focusing physics education on modelling physical systems rather than emphasizing on learning isolated concepts the student approaches the field of physics in a way that has similarity with how professional physicists work. A minor pilot study has been done with a few students in order to test a design for studies on future courses. The pilot focuses on a course in classical mechanics where the students solve problems by creating simulations in for example Matlab. The design involves the students to take the Force Concept Inventory-test as pre-test and post-test in order to map the conceptual knowledge in physics. Students are then interviewed about their solutions. Special emphasis is put on how they troubleshoot their computer programs in order to find out if their approach is based on physics or computer programming. The interviews are complemented with a statement-test with responses on a Likert-scale ranking from “strongly agree” to “strongly disagree”. The design of the study turned out to be relevant concerning the suggested research questions above. More emphasis need to be put on finding out how the students think and learn physics when making the simulations. This could be done by developing exercises which encourage the student to use and reflect on their own solutions for simulations. References: de Jong, T., van Joolingen, W. R. (1998).
