《高中数学新课程标准》指出:“高中数学课程应倡导自主探索、动手实践、合作交流、阅读自学的学习方式、发挥学生学习的主动性,使学生的学习过程成为在教师引导下的再创造”。新课标在课改理念、教材内容、实施措施上都有巨大变化,强烈冲击着现在的教育体系,迫使越来越多的教师注重对传统教学模式的改变。一、创设精彩合适的引入情境,激发学生学习兴趣新课标中强调:“要让学生在现实的情境中和已有知识的基础上体验和理解数学知识。”良好的开端是成功的一半。在这种潜在的指导下,越来越多的教师都开始重视“情境教学、精彩引入”。情境教学就是以课本教材为内容,教师在教学过程中采用从数学文化的视角或从实际生活中的出现的大量例子,让学生在切身体会中感悟新知识,提高学生解决和判断问题的能力,起到帮助教师培养学生创新思维和创造 The new high school mathematics curriculum standard states: “The high school mathematics curriculum should advocate self-exploration, hands-on practice, cooperation and exchange, reading self-study way of learning, give full play to students’ learning initiative, and make the students’ learning process become teachers’ create”. The new curriculum standards have made great changes in the concept of curriculum reform, teaching materials and implementation measures, which have strongly impacted the current education system and forced more and more teachers to pay attention to the change of the traditional teaching mode. First, to create a wonderful and appropriate introduction of the situation, to stimulate students interest in learning The new curriculum emphasizes: “Let students in the context of the actual and existing knowledge based on the experience and understanding of mathematical knowledge. ” Good start is successful half. Under this potential guidance, more and more teachers are beginning to pay attention to “situational teaching, wonderful introduction”. Situational teaching is based on textbooks and textbooks, teachers in the teaching process from the perspective of mathematical culture or from the actual life of a large number of examples, so that students experience in the new knowledge, improve students’ ability to solve and judge problems, Play to help teachers develop students innovative thinking and creativity
