The use of interactive lecture demonstration in teaching high-school physics : magnetic force on a moving charged particle
Abstract:
This research presented the use of Interactive Lecture Demonstration ( ILD) in teaching high-school level on magnetic force on a moving charged particle. The aim of this work was to study grade-12 students understanding on this physics topic and comparing the effectiveness of ILD method to traditional teaching. The ILD teaching module with the Cathode-ray tube as demonstration set had been developed and administrated to high school students. After the instruction, all sample groups conceptual understanding were assessed by the Magnetic Force on a moving Charged Particle Test. In year 2014, the results showed that most students had difficulty of indicating the direction and magnitude of the magnetic force. They were unable to apply the right- hand rule. However, the mean score of the ILD classes was significantly better than that of the traditional class. In year 2015, the mean scores of all sample groups decreased and were extremely low compared to the previous year. Overall, the ILD method could enhance understanding of students with the requirement that some members of each group should have a good background in the subject. In addition, most students lack consistency in answering the same concept questions. However, the number of students who had highest consistency belong to ILD class in 2014.
