新课改对教师提出了更多的教学要求,需要教师注重学生综合素质的培养,比如实践能力、创新精神与创造力、合作交流、收集与处理信息、自主学习等等。同时,在教学过程中,教师需要关注学生们的参与活动,特别是探究活动,关注学生学习过程,不能偏重结果;注重数学应用,培养学生问题意识与解决能力。若要落实上述教学要求,教师需要打破封闭式教学模式,打造开放式课堂,以学生发展为中心,以训练为主线,以问题为载体,教师指导,学生探究,踊跃参与,大胆质疑,积极表达。那么,在小学数学教学中,教师如何构建开放式课堂教学模式?对此,笔者将其流程分述如下。一、情境设置,启思诱趣 The new curriculum reform puts forward more teaching requirements for teachers. Teachers should pay attention to the cultivation of overall quality of students, such as practical ability, innovative spirit and creativity, cooperation and exchange, information collection and processing, autonomous learning and so on. At the same time, in the process of teaching, teachers need to pay attention to students ’participation activities, especially to explore activities, pay attention to the process of student learning, can not emphasize the results; pay attention to mathematics application, cultivate students’ problem awareness and ability to solve problems. To implement the above teaching requirements, teachers need to break the closed teaching mode, create an open classroom, take students ’development as the center, train as the main line, issue as the carrier, teacher’s guidance, students’ inquiry, active participation, bold questioning and positive expression . So, in primary school mathematics teaching, teachers how to construct an open classroom teaching mode? In this regard, I will process is divided as follows. First, set the situation, enlightenment seductive
