有效引导是提高课堂教学有效性的主渠道之一,在数学课堂教学中,教师的引导性语言是实现师生交往互动、沟通交流、理解对话的重要手段。教师的语言引导要体现双向交流,营造启而有发、问而有答、做而有思的氛围,从而促使学生在教师的指导下有新的发现、新的表现。 Effective guidance is one of the main ways to improve the effectiveness of classroom teaching. In mathematics classroom teaching, the instructive language of teachers is an important means to realize the interaction, communication and understanding between teachers and students. Teachers' linguistic guidance should reflect two-way communication, creating an atmosphere of initiation and asking, answering, and thinking, so as to encourage students to find new findings and new performances under the guidance of teachers.
