在传统教育模式下,教师作为知识传授者被比喻为“红烛、春蚕、一桶水”;而教师作为组织者、管理者被比喻为“工程师、园丁、家长、警察、法官”。在教育改革的要求下,教师角色不得不与时俱进,重新转换,从原先的警察、法官转变成朋友、引导者,让学生的学习方式从被动变主动。 In the traditional mode of education, teachers as metaphor of knowledge are compared to “red candles, spring silkworms, a bucket of water”; and teachers as organizers and managers are compared to “engineers, gardeners, parents, police, judges ”. Under the request of education reform, teachers ’roles have to keep pace with the times and change again. From the original police and judges, they have become friends and guiders so that students’ learning styles can be changed from passive to active.
