基于认知理论的中学概率教学策略研究

Study on the Strategies of Teaching Probability in Middle School Based on Cognitive Theories

概率是学生素质的重要组成部分.中学概率教学可遵循以下原则:认识不确定现象,初步体验事件发生的可能性大小;体会概率的意义,了解频率与概率的关系;通过实例进一步丰富对概率的认识,发展随机观念;强调归纳的思维方法;引导学生认真审题,确定合理的解题策略;引导学生一题多解,让学生感受求解概率问题方法的灵活性与多样性;引导学生开展课题研究,增强学生学概率用概率的创新意识与能力.

Probability knowledge was an important part in the quality of the middle school student. The principle to observe that formulate the strategies of teaching probability was provided, based on the middle school students cognition character and their developing level of probability knowledge. Based on the principle, the teaching strategies was provided, The aim was to help the students understand the basic thought of random phenomenon of probability and form the awareness which observed and solved the practice problems with the probability idea, by having an initiative hand in designing scheme, gathering data and making policy.
