浅谈初中数学教学中问题情境创设.doc浅谈初中数学教学中问题情境创设
摘要:问题源于情境。20世纪初,杜威曾提倡过问题教 学,其核心就是问题情境,此教学过程的一般模式为“设置问 题情景一确定问题或课题一拟定解决课题方案一执行计划 —总结与评价”;布鲁纳的问题教学法(又称发现法)也主张 创设问题情境,他认为:“学****者在一定的问题情境中,经历 对学****材料的亲身体验和发展过程,才是学****者最有价值的 东西。”而数学问题情境是学生掌握知识,形成能力,培养创 新意识,发展心理品质的重要源泉。问题情境的创设必须遵 循主题性、启发性、有序性、趣味性原则。问题情境创设方 式有悬念、猜想、类比、故事、游戏等。
