Interactive demonstrations in science classrooms are pedagogical tools designed to actively engage students in the learning process by involving them in hands-on, visually stimulating activities that illustrate scientific concepts. These demonstrations leverage the power of information and computer technologies (ICT) to create dynamic and interactive learning environments. For instance, interactive lecture demonstrations (ILDs) are instructor-led activities that engage the whole class and address students' mental models of core concepts using real-time experiments conducted with sensors, simulations, and data analysis . An example of such a device is one that demonstrates the current magnetic effect, which uses coil modules and a transparent bowl to vividly show the magnetic field generated by current, making the phenomenon both obvious and interesting . In the field of gamma imaging, a safe and engaging demonstration using a rag doll with a localised exothermic reaction has been developed to teach the principles of gamma imaging, significantly increasing student engagement and understanding . Research has shown that interactive demonstrations, especially when combined with discovery learning, can significantly improve students' science process skills, as evidenced by a study where the experimental group using this approach showed a higher normalized-gain average compared to the control group . In chemistry, interactive lecture demonstrations have been used to connect demonstrations more deliberately with course content, engaging students in predicting, observing, and explaining results, which has been found to be effective for learning . The inquiry interactive demonstration model has also been shown to improve students' science process skills and self-regulation, highlighting its effectiveness in educational settings . Technological advancements have further enhanced these demonstrations, such as the integration of projectors with electronic whiteboards, allowing for more interactive and barrier-free teaching experiences . Interactive simulations, which mimic real laboratory conditions, provide a safe, cost-effective, and accurate way to teach scientific concepts, making them a fundamental pillar in science education . The long-term impact of interactive science shows, such as 'Music to your ears,' has been demonstrated, with students recalling a significant portion of the demonstrations even after two and a half years, indicating the lasting cognitive impact of such interactive methods . Finally, the use of Vernier's Wireless Dynamics Sensor System (WDSS) in developing new ILDs for physics classrooms has made it easier for instructors to demonstrate complex concepts like vector forces, torque, and circular motion, further showcasing the versatility and effectiveness of interactive demonstrations in enhancing conceptual understanding . Overall, interactive demonstrations in science classrooms are powerful tools that not only make learning more engaging and enjoyable but also significantly improve academic outcomes and conceptual understanding.
