The purpose of this study was to investigate elementary science teachers’ conception about animal reproduction in Taichung area. Research tools were open-ended questions, “animal reproduction conception” questions designed by researcher and interview instruments. We investigated if the animal conception will differ due to genders, teaching experiences, educational level and education background.
Research investigated science teachers selected from 46 elementary schools in Taichung city and county. Total valid samples are 257 with a recovery rate of 83.4%. From the data obtained by quantitative descriptive statistics, t test, one-way ANOVA and qualitative interview data, we found that：
1. Most nature science teachers have good understanding in “meanings and purposes of reproduction”. However, some of them explain animal reproduction by “insemination” or “copulation”; some did not regard fission as a way of reproduction.
2. As to asexual reproduction, most teachers can point out at least one characteristics of asexual reproduction. However, misconceptions such as individuals can be generated through meiosis, or asexual reproduction equals to hermaphroditism do exist.
3. Some teachers restricted reproduction in “sexual reproduction” only. Some of them explained sexual reproduction by mating behaviors or internal fertilization.
4. Teachers’ conception in viviparity and oviparity is more clear than in ovoviviparity. Some thought embryos got nutrition from ovum and mother, others thought eggs were bred in the mouth.
5. Teachers’ conceptions about animal reproduction are：1.There is no obvious difference between male and female teachers. 2.There is an obvious difference between teaching experience. 3.There is no obvious difference between educational level. 4.There is an obvious difference due to the education background. Teachers with science background are better than teachers with other background.
6. From the interview data, the teachers tend to have positive attitude toward the current course materials about animal reproduction. However, they hope that materials can be more close to life experience, and that the publishers can provide more teaching resources and information.
