Teaching Physical Sciences in B.Ed Context Using PhET Interactive Simulations for Teaching Chemistry, Physics & Mathematics At B.Ed Hons level, preparing future teachers to teach Physical Sciences effectively requires integrating pedagogical knowledge, content knowledge, and technology ( TPACK framework) .  One powerful digital tool for this purpose is PhET Interactive Simulations , developed by Carl Wieman at the University of Colorado Boulder in 2002.  PhET (Physics Education Technology) approach provides free, research-based simulations that promote inquiry-based and conceptual learning. Below is a structured discussion for B.Ed Hons level students on teaching Matter (Chemistry), Circuitry & Electricity (Physics), and Algebra (Mathematics) using PhET. 1. Teaching Chemistry: Concept of Matter Topic: States of Matter & Particle Theory Why Use PhET? Concepts such as atomic structure, particle motion, and intermolecular forces are abstract. PhET simulations make ...
