教学语言是体现教学功能的渠道之一,是决定学生学习效果高低的重要因素。要上好一堂生物课,教师应当集中展示其独具特色的教学设计、科学的生动的课堂语言、引人入胜的课堂导入、启迪思维的课堂提问和“画龙点睛”的结课等课堂教学艺术。 Teaching language is one of the channels to reflect the teaching function, which is an important factor that determines the level of students’ learning. To take a good biology class, teachers should focus on displaying their unique teaching design, scientific and vivid classroom language, fascinating introduction of the classroom, inspiring thinking in class questions and “finishing touch ” end of class teaching art.
