How can Phet enhance content presentation?

Phet can be used in science to represent models of scientific laws, principles and biological processes such as molecular and nucleus structures, forces, particle theory, diffusion and many other various models. 

Looking back to the TPACK model, content and technology (CK), it is important for educators to consider how the technology can be used for different content. 

Science is a disciplinary area which its content demands specific representational requirements that are complimented by technologies. Phet is an example of a a free technology that can be used in science for learners to create models, to deconstruct them or apply laws and understand principles (Bower, 2017). 

Does Phet meet the learning requirements of the science discipline?

 Bloom's taxonomy framework offers a continuum of different cognitive abilities that can be incorporated into this e-learning design lesson; for example using Phet simulation "build a molecule" will achieve the cognitive levels of Bloom's taxonomy, apply, understand, analyze and create. This simulation can helps students apply their knowledge of the periodic table, compounds and molecule structures and analyze the designed molecules by deconstructing the elements and bonds (Astuti, 2018). 

Phet provides an appealing and interactive interface with features of observations and manipulations that creates a game like environment to help learners develop a solid understanding of the principles being taught. 

Phet meets the conceptual knowledge goal of Bloom's taxonomy through a constructivist and/or inquiry/problem-based approach. Phet requires students to apply principles and concepts of the phenomenon, operational knowledge, investigative and analytical acquisitions. Students model the principles and are engaged in modifying, deconstructing and adding properties of a simulated model. 

Learning through exploration complimented by computer simulation demands for high cognitive engagement (Banda & Nzabahimana, 2023).
