高中生物的新课程标准要求要彻底摈弃过去以教师为中心的传统观念,重新调整与设计课堂教学活动,提高其效率性。这就要求生物教师重新设计教学活动,成为教学活动的指导者、组织者与课堂内容的建构者,满足学生的多方面需求。在效率性建设方面,教师要根据新的课程理念,通过创新课前预习、多媒体综合运用、教师语言等内容,努力提高课堂教学效率,以满足学生终身发展的需要。 The new curriculum standard of high school biology requires that we completely abandon the traditional teacher-centered concepts and readjust and design classroom teaching activities to improve their efficiency. This requires biological teachers to re-design teaching activities, teaching activities as a guide, organizers and classroom content builders to meet the diverse needs of students. In terms of efficiency building, teachers should strive to improve the efficiency of classroom teaching to meet the needs of students’ lifelong development according to the new curriculum concept through innovative pre-class preview, comprehensive multimedia application, and teacher’s language.
