Therefore,it can stimulate effectivelystudents' points of interest and improve learning initiative to achieve the effective combination of four-point-breakthrough teaching and practicing.Key words: four-point-breakthrough; combination of number and shape; core literacy; mathematical ofmathematics modelin“四点突破”是贵州省初中数学张瑛名师工作室提出的基本教学理念,是指以兴趣点、重点、难点、目标达成点的突破作为课堂教学的基本要求,融会于每一课堂的教学实践中,以抓住教学的本质,调动学生的学...
