Abstract: Recent developments in science will impact the practice of teachers who teach bioethics in schools. There is a growing awareness of bioethical issues amongst the public and in the media, and an increasing level of debate about them. It is important that teachers and those who teach biology are aware of the ethical and social implications of their work. This paper reviews and critiques the existing research on some bioethics, which deals with ethics in the context of science instruction. First, bioethics and bioethical issues are described. This is followed by an importance of bioethics education. Then the existing studies (on bioethics) are reviewed and evaluated. Because of the gaps with the existing research in the literature, recommendations are made describing the need for more and better designed research.
