电教媒体的出现,使小学数学课堂教学发生实质性的变化,为小学数学课堂教学改革提供了强有力的手段保障。教师应科学利用电教媒体手段,揭示数学知识的形成过程及本质,落实数学思想与方法,优化教学环节,突破教学难点,培养学生数学分析能力和思辨能力,提高数学课堂教学质量。
The appearance of audio-visual media makes the elementary mathematics classroom teaching change substantially, which provides a powerful means guarantee for the elementary mathematics classroom teaching reform. Teachers should use the means of audio-visual media scientifically, reveal the formation process and essence of mathematical knowledge, implement the mathematical ideas and methods, optimize the teaching links, break through the teaching difficulties, develop students’ mathematical analysis ability and speculative ability, and improve the quality of mathematics classroom teaching.
