精心创设情境是提高数学课堂教学有效性的一项重要策略。然而,新课程下的一些数学课,情境只是为创设而创设,只图表面热闹,有的甚至成了说话课,夹杂了太多的非数学信息,干扰和弱化了数学知识和技能的学习以及数学思维的发展,缺乏情境创设的有效性——为学生学习数学服务。结合自身的教学实践,就如何创设情境提高小学数学课堂教学的有效性谈几点认识。一、创设情感情境——提高学生的学习热情课堂教学除知识对流的主线外,还有一条情感对流的主线。师生关系好,彼此心里相容,教与学双方都会沉浸在轻 Careful creation of context is an important strategy to improve the effectiveness of classroom teaching in mathematics. However, some math classes under the new curriculum are created only for the sake of creation. They only have a lively surface. Some even become talkative lessons, contain too much non-mathematical information, interfere with and weaken the learning of math knowledge and skills, and The development of mathematical thinking, the lack of effectiveness of situational creation - for students to learn mathematical services. Combined with its own teaching practice, talk about how to create a situation to improve the effectiveness of primary school mathematics classroom teaching. First, the creation of emotional situations - to enhance students’ enthusiasm for learning In addition to the main line of knowledge convection classroom teaching, there is a main line of emotional convection. Good relationship between teachers and students, mutual mentality, both teaching and learning will be immersed in the light
