Active Learning Approaches by Visualizing ICT Devices with Milliseconds Resolution for Deeper Understanding in Physics

We are developing various modularized materials in physics education to overcome students’ misconceptions by use of ICT, i.e. video analysis software and ultra‐high‐speed digital movies, motion detector, force sensors, current and voltage probes, temperature sensors etc. Furthermore, we also present some new modules of active learning approaches on electric circuit using high speed camera and voltage probes with milliseconds resolution. We are now especially trying to improve conceptual understanding by use of ICT devices with milliseconds resolution in various areas of physics education We give some modules of mass measurements by video analysis of collision phenomena by using high speed cameras—Casio EX‐F1(1200 fps), EX‐FH20(1000 fps) and EX‐FC100/150(1000 fps). We present several new modules on collision phenomena to establish deeper understanding of conservation laws of momentum. We discuss some effective results of trial on a physics education training courses for science educators, and those for sci...

Progress of Systematic Hands on Devices for Active Learning Methods by Visualizing ICT Tools in Physics with Milliseconds Resolution

We are developing various systematic hands on devices [1,2] for progress of active learning (AL) to improve students’ conceptual understanding in physical laws. Recently, those are improved drastically by using visualizing ICT tools with milliseconds resolution, e.g. the following hands on ICT-based devices are very effective for conceptual understanding in physics by analyzing high speed moving phenomena of real world with milliseconds resolution or slowly moving world, i.e.  AL by blowgun darts systems, or ultra light cart-fun systems, toy hover soccer-ball systems, or CMS collision systems of pendulums-balls etc.  AL by Hands on frictionless plains made of glass beads on acrylic board.  Laws on terminal velocity for falling super-light paper cups in frictional world.

Towards Scientific Conception Acquisition under Ubiquitous Environment

We introduce ICT‐based applications, offering students to shape their scientific concepts. Students’ misconceptions are coming from their daily life and robust even after studying physics. These tendencies are significant on invisible phenomena. Visualization of these phenomena may be one of the solutions to overcome their naive concepts. We have developed ICT‐based various modules to visualize phenomena. These modules are useful and effective enough to change students’ concept dramatically. We also propose some experiments through the active utilization of ICT tools.

Phase Structure of a Quantized Chiral Soliton on S3

A quantization of a breathing motion of a rotating chiral soliton on S 3 is performed in terms of a family of trial functions for a profile function of the hedgehog ansatz. We determine eigenenergies of the quantized S 3 skyrmion by solving the Schrodinger equation of the breathing mode for several lower spin and isospin states varying the Skyrme term constants e. When S 3 radius is smaller than 2/ef π , where f π is the pion decay constant, we always obtain a conformal map solution as the lowest eigenenergy state. In the conformal map case, allowed states are either symmetric or anti-symmetric under the inversion of a dynamical variable describing the breathing mode
