“简约”给人一种明了、凝练的感觉,在去繁就简中又极其完美地保留了事物本身的经典内核。它既是操作的要领,又是理想目标,还是一种教学理念。它能使我们的数学课堂变得更为简洁、清晰、深刻,进而实现课堂教学的优质和高效。而数学模型就能将思维过程简约化,能有效地反映思维的过程,是将思维过程用语言符号外化的结果。一、现状与思考 “Simple ” gives a clear, concise feeling, in the elaborate Jane and extremely perfect retain the classic core of things themselves. It is both the essentials of operation, but also the ideal goal, or a teaching philosophy. It can make our mathematics classroom become more concise, clear, profound, and thus achieve the quality and efficiency of classroom teaching. The mathematical model can simplify the process of thinking, can effectively reflect the process of thinking, the process of thinking is the result of externalized language symbols. First, the status quo and thinking
