《数学课程标准(2011版)》指出:培养学生的数学符号意识是数学教学的重要任务之一。数学符号的学习贯穿数学学习的每个阶段,培养学生的符号意识,既易于帮助学生学好数学,又能够帮助提高学生的数学思维能力。然而,在教学实践中发现,因为不能够理解并使用符号语言而导致学习困难的学生大有人在,因为不具备应有的符号意识而导致基础薄弱的学生亦大有人在。因此,深入挖掘研宄培养学生符号意识的有效教学策略已迫在
Mathematical Curriculum Standard (2011 Edition) points out: Cultivating students’ awareness of mathematical symbols is one of the important tasks of mathematics teaching. Mathematical symbols learning through each stage of mathematics learning, cultivate students ’sense of symbols, not only easy to help students learn mathematics, but also can help improve students’ mathematical thinking ability. However, it is found in teaching practice that many students who can not understand and use the symbolic language to cause learning difficulties are in large numbers due to their lack of proper sense of symbols and their weak foundation. Therefore, it is imperative to find out more effective teaching strategies to further develop the symbolic awareness of students
