《Z+Z 超级画板》(以下简称《画板》)不同于其它计算机绘图软件,它所作出的图形、图像都是动态的,而且注重数学表达的准确性,它最突出的优点是使图形、图像在变动的状态下保持不变的几何关系。线段的中点永远是中点。平行的直线永远保持平行。这样就可以帮助学生从动态中去观察、探索和发现对象之间的数学关系与空间关系,可以利用它培养学生的能力、开发学生的智力、发挥学生的创新精神,达到数学教学大纲的要求。下面笔者就运用《画板》解决数学重难点谈一些做法和体会。1.学生参与教学过程。《画板》给学生自己动手、为学生参与教学过程、发现问题、讨论问题提供了很好的园地。在网络教
“Z + Z Super Sketchpad” (hereinafter referred to as “drawing”) is different from other computer graphics software. Its graphics and images are dynamic, and it emphasizes the accuracy of mathematical expressions. Its most prominent advantage is to make graphics, The image maintains a constant geometric relationship in a changing state. The midpoint of the line segment is always the midpoint. Parallel lines are always parallel. This can help students observe, explore and discover the mathematical relationship and spatial relationship between objects from the dynamics, and can use it to cultivate students’ abilities, develop their intelligence, and exert their innovative spirit to meet the requirements of the mathematics syllabus. Here I use the “painting board” to solve some of the difficulties and experiences of mathematics. 1. Students participate in the teaching process. “Painting Board” provides students with hands-on activities and provides a good place for students to participate in the teaching process, find problems, and discuss issues.
