| The development of biological science and technology not only has brought about a social development, but also has resulted in many social ethical problems, leading to the huge effect on the life of middle school students. For example, the lack of values and the wrong attitudes to life have played a key role in growing number of suicide or murder in middle school students, which we have to attach great importance to. So it is necessary and urgent for the middle school students to learn bioethical knowledge to strengthen their life ethics.The main purpose of this article is to explore how to carry out the life ethics teaching in high schools to enhance the students’ cognition of life ethics and build up their moral values. It is teachers who are the perpetrators of the courses. Consequently, teachers’ cognition of life ethics and their willingness to implement will affect the ethical education of high school life. Through questionnaires, interviews and other research methods, we had a preliminary investigation among high-school biology teachers about "understanding bioethics and its teaching circumstances ". it is shown that the teachers have a certain understanding of Bioethical issues, and they are willing to integrate life ethics education into classroom teaching. But the limit of teachers’ understanding of life ethics and their low self-efficacy cause the poor integration of life ethics education in senior high school. On the other hand, the students are very interested in bioethics issues. As a result, we should try our best to improve students’ understanding of life ethics effectively in the teaching process.In order to further promote life ethics education in high school, the author put forward the following strategies to specialize them, such as strengthening teachers’ understanding of bioethical issues, improving teachers’ bioethics teaching methods and increasing their opportunities of participation in life ethics related trainings. At the same time, we need to make clear the specific content of developing student’s ethics, enrich the teaching content of students’ life ethics, create a rich life ethical atmosphere and perfect relevant education mechanism to promote the integration of life ethics education in high school. |
