人教版新教材中新增加了一个单元“数学广角”“找次品”的教学。通过简单的事例渗透一些重要的解决问题的策略和数学思想方法,一是让学生在解决这些问题的过程中能主动尝试从数学的角度运用所学知识和方法寻找解决问题的策略,其二,接触一些数学思想方法,亲历观察、猜测、实验、比较、推理、归纳等数学探索的过程,培养学生解决实际问题的实践经验和能力。其三,通过解决问题,激发学生对数学的好奇心和求知欲,并能够运用思想方法和特殊的解决策略,为学生的数学能力的可持续发展铺设地基。
PEP new teaching materials to add a new unit “mathematical wide angle ” “find defective ” teaching. Through simple examples, we can infiltrate some important strategies for solving problems and ways of thinking and mathematics. First, students should take the initiative to try their best to find solutions to problems from the perspective of mathematics in the process of solving these problems. Second, Contact with some mathematical ideas and methods, witness the process of mathematical exploration such as observation, speculation, experiment, comparison, reasoning and induction, and cultivate students’ practical experience and ability to solve practical problems. Third, by solving problems, students are encouraged to be curious about curriculums and curiosities and to apply the method of thinking and special strategies to lay a foundation for the sustainable development of students’ mathematical abilities.
