Pre-service teacher ideas about designing demonstration set in physics education program

This study aims to explain the idea of pre-service teachers about designing demonstrations used by teachers when the process of physics learning is simple. Research sample on 25 pre-service physics teacher. The research method is the descriptive method. The research instrument uses an observation sheet and interview format. Observations indicate that 51% of pre-service teachers can design demonstrations through analysis of laboratory activities in schools to obtain demonstration ideas, 34% of potential teachers can design demonstrations through project tasks and 37% depending on initial knowledge about demonstrations. Student ideas include low category and frequency level through literature studies of physical content, literature studies on experiments, natural phenomena and daily life experiences. These results imply that instruction in physics lab studies leads pre-service teachers to have a more scientific understanding of designing demonstrations.
