近年来,随着新课程改革的不断深入,以教师为中心,从教师的教出发,学生被动接受,不愿学、不会学、听不懂、教学效益低的教学状况制约着课堂教学效益,影响了学生未来的发展。从目前教学的实际看,教学改革势在必行,导学案教学中问题引导的有效设计,能让学生积极主动地学习,参与课堂研究,全面提高学生的学习自主性和科学素养。在数学课堂教学中,数学问题是推动数学发展的主要动力,数学问题的价值往往不仅在其本身,而在于寻求对其解决的过程当中。因此,一个好的问题,能激发学生学习兴趣,开拓学生思维,把学生的思维引向一定的高度与深度。因此教师能设计出行之有效的问题来引导学生学习,让学生围绕问题引导这一环节中的有效问题进行自主学习、合作探究等活动。教师从问题的设计——学生的探究学习——解决及应用的过程中提高学生的数学素质,提高学生的创新意识及实践能力。
In recent years, with the continuous deepening of the new curriculum reform, taking the teachers as the center, starting from the teachers ’teaching, the students’ passive acceptance, the unwillingness to learn, the unintelligible, the poor teaching benefit restrict the teaching effectiveness of the classroom , Affecting the future development of students. From the current teaching practice, the teaching reform is imperative. The effective design of problem-guided teaching in case teaching can enable students to actively study and participate in classroom research to improve students’ learning autonomy and scientific accomplishment. In mathematics classroom teaching, mathematics is the main driving force to promote the development of mathematics. The value of mathematical problems often lies not only in itself, but in the process of seeking solutions to them. Therefore, a good question can stimulate students’ interest in learning, develop students’ thinking and lead students’ thinking to a certain height and depth. Therefore, teachers can design effective problems to guide students to learn, so that students around the problem guide the effective aspects of this link for autonomous learning, cooperative exploration and other activities. Teachers from the design of the problem - students inquiry learning - to solve and apply the process of improving students ’mathematical quality, improve students’ innovative awareness and practical ability.
