Our study monitored students' alternative conceptions about some fundamental terms and processes of gene technology. Novice secondary school 10th graders (144 in total) described their conceptions in an open questionnaire. Using inductive category development, we iteratively categorized their responses. We found 13 categories describing students' conceptions. Common categories were allocated to more than one different term or process. Specific categories were found only in the context of explaining one term or process. Using the collected conceptions, we then developed a questionnaire, which we administered to monitor the students' conceptual change during a hands-on approach in our outreach lab. Knowledge about these conceptions and the concepts' consideration within science teaching should be of value both for pre-service teacher education and for professional development of in-service teachers.
