Data collection
Biology student teachers’ understanding of the mitosis and meiosis was examined by two different methods not mutually exclusive: 1.) students’ drawings and 2.) individual interviews. The drawing method was chosen to enable a deep, distinctive insight into the students’ understanding (Rennie and Jarvis, 1995). The participating students were asked to draw mitosis and meiosis in a cell on a blank piece of A4-sized paper. The participants were informed about the drawing method before this application. Also some practices were applied about this method. In addition, individual interviews were conducted about the detailed subjects with 15 randomly chosen students who demonstrated misconceptions. The
purpose was to check the validity of the interpretation of the drawings. In the interview, these students were asked to respond to questions like “What are chromosomes?,” “When does DNA replication occur in a cell?,” “What are the differences and similarities between mitosis and meiosis?,” “What happens to the cell organelles during the cell division process?,” “How do the chromosomes act during mitosis and meiosis?.” Their responses are given below by comparing with the drawings.
