Exploring the opinions of pre-service science teachers in their experimental designs prepared based on various approaches

The students in working in laboratories in 21st century are preferred to take place as active participants in the experiments coming up with their own designs and projects by developing new ideas and problems rather than implementing the ones told and ordered by others during these experiments. The science teachers that would have the students undertake these roles would be needed to know and have experienced various experiment designs and projects. From this point of view, in this study; it is aimed to receive their opinions on experimental designs prepared based on 5E, scientific process skills and constructivist-approach. The pattern of the study happens to be a case study and the data is gathered by directing seven open-ended questions to the 42 teacher candidates on their three experiments. In the end, it was established that the teacher candidates have had opinions in favour of the experiment designs.
