Research On The Cultivation Of Critical Thinking In Senior High School Biology Teaching Under The Key Competencies Concept

In the international economic cooperation and Development Organization(OECD)put forward the key competencies,the countries around the world to actively build the core content of the specific content,the development of the core quality of students.China has officially launched the key competencies of China students development,critical questions is one of the important content of China's key competencies,critical thinking as an important tool for critical questions,teachers should cultivate quality is an important thinking in teaching.Therefore,the author under the initiative of the key competencies concept,how to cultivate students' critical thinking in high school biology teaching.First of all,through reading the literature,in-depth understanding of the status of critical thinking at home and abroad,combing the definition,composition,measurement and other basic theories of critical thinking.Then,in order to understand the students' critical thinking level and the teacher's critical thinking teaching situation,so as to develop effective and critical thinking training strategy,the author investigates the critical thinking dispositions and skills level of the four science students in the high school group of the internship school,the results show that the students' critical thinking dispositions and skills are at a medium level,which needs to be improved;Using the questionnaire survey method and the interview method combined with the form of the author's practice of school teachers critical thinking teaching status survey,Survey results show that the majority of teachers of critical thinking more one-sided understanding of the theory of critical thinking poorly understood and rarely carry out development activities critical thinking in teaching,teachers' critical thinking level needs to be improved.On the basis of the investigation of the critical thinking level of the students,in order to improve the students' critical thinking level,the author puts forward the critical thinking cultivation strategy from the aspects of classroom teaching and extracurricular activities.Classroom teaching from the new teaching,experimental class,practice class three different types of comprehensive and concrete training of students' critical thinking;Extracurricular activities from the debate activities,social software under the class,the establishment of self-evaluation mechanism,etc.will be critical thinking of the students into the daily study and life.On the critical level of thinking of the two classes of teaching experiments,experimental classes in teaching into the critical thinking of the training strategy,the control classes follow the traditional teaching.After a semester of teaching experiments,the experimental class students' critical thinking dispositions and critical thinking skills level increased slightly.There was no significant improvement in the critical thinking dispositions and skills level of the students in the control class.It is hoped that this study will provide a reference for the first-line teaching staff to train students' critical thinking.
