Tackling the Challenges of Acquiring Web Videos for STEM Hands-On Learning: Example of a Fake Hologram and a Proposed Learning Model

The web offers rich learning resources, including technology education. With the advocate of hands-on learning and STEM education, many web videos teach users how to use technological tools to create STEM artifacts and acquire related science knowledge. These videos were adopted by teachers in their classroom and followed closely as pro-claimed technology education. As web credibility is a challenge and how students approach the topics to develop systematic knowledge are crucial, this study proposed a learning model to address these challenges. The model was embedded into a teacher training to have teachers self-experience these challenges. Participating teachers were expected to construct their pedagogical knowledge inductively, and their responses to the proposed learning were collected. With the participation of 27 in-service teachers, the results demonstrated teachers' recognition and support of the proposed model. However, their beliefs and concerns regarding its implementation generated uncertainty. Study results broaden the spectrum of hands-on teacher training.
