创设问题情境是促使学生开展有效学习的有力手段,所以需要我们的教师建设性、创造性的使用教材,创设出适合学生开展有效学习的问题情境。要处理好探索性与高效性的关系,问题情境的创设应以学生需要的动机为中心,充分让他们探索。寻求解决问题的策略,使他们能主动、有效地参与学习。要处理好生活性与数学性的关系,当问题情境与火热的生活紧密相连时,既能突出生活性又能提高学生的学习热情。要处理好时效性与延展性的关系,学起于疑、成于思,每节课结束时,应设法给学生留点余味,使学生有“课已完而味无穷”之感。
Creating problem situations is a powerful way to promote effective learning. Therefore, our teachers are required to use constructive and creative teaching materials to create problem situations that are suitable for students to carry out effective learning. To handle the relationship between exploratory and effective, the creation of problem situations should focus on the students’ motivation and fully allow them to explore. Seeking solutions to problems so that they can participate actively and effectively in learning. To handle the relationship between life and mathematics, when the problem situation and fiery life are closely linked, both to highlight the vitality and improve students’ enthusiasm for learning. To deal with the relationship between timeliness and ductility, learn from doubt, into thinking, the end of each class, should try to give students leave aftertaste, so that students have “class finished and taste infinite ” feeling.
