Discrepant teaching events are a powerful tool for addressing student misconceptions and promoting critical thinking skills (Longfield, 2009). These events involve presenting students with a surprising or unexpected phenomenon that challenges their existing understanding of a scientific concept. Through the exploration of this phenomenon, students are encouraged to question their assumptions and develop a deeper understanding of the underlying principles at work. Discrepant teaching events can be used in both hands-on and video-based learning environments. In hands-on learning, students have the opportunity to interact directly with the phenomenon, which can enhance their engagement and understanding. In video-based learning, on the other hand, students can observe the phenomenon in action and analyze it from multiple perspectives, which can promote critical thinking and problem-solving skills. Hands-On Learning - Involves physical manipulation of materials - Provides tactile feedback and sensory experience - Allows for immediate correction and adjustment - Encourages active engagement and participation - May require more time and resources for preparation and implementation Video-Based Learning - Involves watching videos or demonstrations - Provides visual and auditory information - Allows for self-paced learning and repetition - Requires less time and resources for preparation and implementation - May lack the hands-on experience and feedback The 'Heavy Newspaper' Experiment is a classic science experiment that demonstrates the incredible power of air pressure. In this experiment, a sheet of newspaper is used to create a vacuum, which can lift a heavy object like a car or a person. The experiment has been used in classrooms and science museums around the world to teach students about air pressure and its effects on objects. The 'Heavy Newspaper' Experiment is a great example of a discrepant teaching event, which is a teaching technique that involves presenting students with two or more phenomena that are not
similar in terms of their observable properties. The goal of discrepant teaching events is to help students develop a deeper understanding of scientific concepts by contrasting them with something that is familiar or easy to understand. In the case of the 'Heavy Newspaper' Experiment, the discrepancy between the weight of the newspaper and the weight of the object being lifted is a clear example of a discrepant teaching event. By demonstrating the incredible power of air pressure, the experiment helps students understand the concept of pressure and its effects on objects in a way that is both engaging and memorable. Comparing and Contrasting the Two Approaches Hands-On Learning - Active participation in the learning process - Opportunity to apply theoretical concepts in a practical setting - Ability to ask questions and receive immediate feedback Video-Based Learning - Flexible learning schedule - Access to a wide range of educational resources - Ability to pause, rewind, and re-watch lectures Merits of Hands-On Learning - Hands-on learning provides a more engaging and interactive experience for students. - Hands-on learning allows students to practice critical thinking, problem-solving, and decision-
making skills. - Hands-on learning can improve retention and understanding of concepts by providing a more concrete and memorable experience. - Hands-on learning can better prepare students for real-world applications and careers. Demerits of Hands-On Learning - Hands-on learning can be time-consuming and may not be feasible in certain situations.
- Hands-on learning can be expensive due to the cost of materials and equipment needed for the activity. - Hands-on learning may not be suitable for all learners, especially those who are more visual or auditory learners. - Hands-on learning can be messy and may require additional time and effort for clean-up and preparation. Merits of Video-Based Learning - Flexibility and Convenience: Videos can be accessed anytime and anywhere, allowing learners to study at their own pace and convenience. - Improved Retention: Videos are more engaging and can help learners retain information better compared to traditional classroom lectures. - Increased Accessibility: Videos can be translated and captioned, making them accessible to learners who speak different languages or have hearing impairments. - Cost-Effective: Video-based learning can be more cost-effective than traditional classroom learning, as it eliminates the need for physical classrooms, travel, and other associated costs. Demerits of Video-Based Learning - Lack of interaction with the instructor or other students. - Difficulty in clarifying doubts or asking questions in real-time. - Tendency to become passive learners and not engage as actively as in hands-on learning. - Limited opportunities for practical application and skill development. - Potential for distractions or lack of focus due to external factors.
