Application of computer simulations in modern physics education István Basa ELTE Fizika Doktori Iskola Fizika Tanítása Program
Challenges in teaching modern physics • What is modern physics? – physics based on new theories found in the early 20th century – physics used for understanding the underlying processes of the interactions of matter – physics currently in development? – physics they use for our more and more common everyday tools! https://en.wikipedia.org/wiki/File:Modernphysicsfields.svg
Challenges in teaching modern physics • Teaching modern physics is essential... ...I guess? Hungarian curriculum: • 7-11th grades (12-17 yrs) • 7-8th grades: brief overview without modern physics • 9th grade: dynamics, fluid dynamics • 10th grade: thermodynamics, electrostatics, direct currents • 11th grade: – first term: oscillations, waves, electromagnetism, alternating currents – second term: optics, astronomy and MODERN PHYSICS including photoelectric effect, blackbody radiation, relativity, atomic models, nuclear physics
Challenges in teaching modern physics Challenges in teaching modern physics • Teaching modern physics is challenging itself – far-from-everyday-approach theories – too small, too fast or too slow scales – too many participants – lack of experimental tools • ...yet not that hard... – motivating topics – easy-to-use laws and formulas ℎ𝑔 = 𝑉 + 𝐹 𝑙𝑗𝑜
Using computer simulations • How computer simulations can solve these? – far-from-approach theories – too small, too fast or too slow scales, too many participants – lack of experimental tools – lack of time in the curriculum
Using computer simulations Using computer simulations • How computer simulations can solve these? far-from-approach theories – too small, too fast or too slow scales, too many participants – lack of experimental tools – lack of time in the curriculum Simulations can simplify images ...and with great simplification comes great responsibility!
Using computer simulations Using computer simulations • How computer simulations can solve these? far-from-approach theories too small, too fast or too slow scales, too many participants – lack of experimental tools – lack of time in the curriculum Simulations can be fast or slow enough You can work with many participants
Using computer simulations Using computer simulations • How computer simulations can solve these? far-from-approach theories too small, too fast or too slow scales lack of experimental tools – lack of time in the curriculum Simulations need only one computer – Students can experiment, observe and obtain own experiences – Students can manipulate, measure and discover on their own
Using computer simulations Using computer simulations • How computer simulations can solve these? far-from-approach theories too small, too fast or too slow scales lack of experimental tools lack of time in the curriculum Digital classrooms, project works
Using computer simulations Using computer simulations • Plans on research and development of my PhD – explore currently available simulations and researches in the topic – develop and test 8-10 simulations in topics such as the photoelectric effect, brownian motion, atomic models and nuclear physics • experiments and measurements are both vital parts • develop and test student activities – introduce the simulations in several schools nation- and worldwide – compare results with control groups • possible changes in approach and understanding • possible progression in solving exercises • possible motivational aspects
Simulating the photoelectric effect • The simulation – JetBrains WebStorm – Html5-based simulation (multiple devices, even smartphones)
Simulating the photoelectric effect Simulating the photoelectric effect • Existing simulations – http://lectureonline.cl.msu.edu/~mmp/kap28/PhotoEffect/photo.htm • few visual implements • current vs voltage graph is wrong • current vs wavelength graph is problematic • few optional student activities
Simulating the photoelectric effect Simulating the photoelectric effect • Existing simulations – http://lpscience.fatcow.com/mgagnon/Photoelectric_Effect/photoelectriceffect1.htm • few possible settings • cannot make graphs • visuals are problematic • few optional student activities
Simulating the photoelectric effect Simulating the photoelectric effect • Existing simulations – http://www.walter-fendt.de/ph14e/photoeffect.htm • graphics a little confusing • no visual implements • few options • few optional student activities
Simulating the photoelectric effect Simulating the photoelectric effect • Existing simulations – http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=342.0 • both automatic and manual settings, dynamic view • more realistic approach, yet problematic graph and curve • few possible settings
Simulating the photoelectric effect Simulating the photoelectric effect • Existing simulations – http://phet.colorado.edu/en/simulation/photoelectric • great visual implements • realistic simulation and data • dynamic settings • few possible measurements
