《数学课程标准》明确提出要“让学生在生动具体的情境中学习数学”。新课程认为,学生的学习过程是一个积极主动的建构过程,是学生依据先前的认识结构主动和有选择地直觉外在信息,建构其意义。课程的意义在于为学生创设一个与知识相遇的情境,在这一情境中教师帮助学生将知识作为探究的起点,利用自己已有的经验与知识进行对话,经过探究性活动对知识进行重新建构。 The Mathematics Curriculum Standard explicitly states that “Let students learn mathematics in vivid, concrete contexts.” The new curriculum believes that the student learning process is a proactive construction process, in which students actively and selectively intuitively perceive external information based on previous cognitive structures and construct their meaning. The significance of the course lies in creating a situation for students to meet with knowledge. In this situation, teachers help students to use knowledge as a starting point for inquiry, use their own experiences to talk with knowledge, and reconstruct knowledge through inquiry activities.
