在师生共同的生活世界中教学相长,是教师专业发展的重要方面。教学过程终结了,教师淡出课堂教学,学生得到发展,但教师的发展没有终结,而是由课内走向课外,学生是发展的,教师也是发展的。学生在教师的发展中成长,教师在学生的成长中发展。 In teachers and students living in a common world of education, teachers professional development is an important aspect. The end of the teaching process, teachers fade out of classroom teaching, students have been developed, but the development of teachers is not the end, but from class to extra-curricular, students are developing, teachers are also developed. Students grow in the development of teachers, teachers in the growth of students.
