聚焦数学本质,促进数学理解是数学教学的永恒追求。数学教学中,新知引入时应该追本溯源,新知探究时注意探本穷源,新知应用时重视强本固源。教师通过深度引领与智慧点拨,促进学生实现数学深度理解,发展智慧。 Focusing on the nature of mathematics and promoting mathematical understanding are the eternal pursuit of mathematics teaching. In mathematics teaching, when new knowledge is introduced, it should be traced back to original source. When new knowledge is explored, attention should be paid to probing into poor sources. Teachers through the depth of guidance and wisdom, to promote students to achieve a deep understanding of mathematics, development of wisdom.
