Abstract
With rapid developments in genetic screening there has been increasing concern about the poor level of understanding of inheritance within the general population. In 1989 a national curriculum was introduced in England and Wales for all students up to the age of 16. This study investigated the knowledge and understanding of genetics amongst 482 students nearing the end of compulsory education. Data were collected using written questions and small group discussions. Findings showed a poor understanding of the processes by which genetic information is transferred and a lack of basic knowledge about the structures involved (gene, chromosome, cell). Few 'alternative conceptions' were identified. Instead there appeared to be widespread uncertainty and confusion. The current approach to science education, as reflected in these findings, does not appear to provide an effective preparation for students - either for future training as scientists or for interactions with science in their personal life.
