【摘要】 当今社会,基础教育改革开展的如火如荼,提倡素质教育,培养创新人才已成为教育的重中之重。21世纪的竞争是科技的竞争、人才的竞争,教育的成败关系到国家队兴衰存亡。要培养出创新人才,需要培养问题意识,而问题意识离不开问题情境。好的问题情境能吸引学生的注意力,提高学习的积极主动性,让学习变得生动有趣,在自发自主的探究学习过程中,培养了创造力。正因为数学情境如此重要,新《课标》在各个学段都给出教学建议,要求要创造丰富的现实情境开展教学。而目前情境教学开展的情况并不理想,许多学生还是感觉学数学很痛苦,枯燥乏味。这主要还是因为部分教师抱着传统教育不肯丢弃,情境教学意识淡薄或不太会创设有限合理的情境开展教学。本文针对以上现状,先大量阅读了有关情境创设的相关文献资料及理论知识,在理论层面研究了情境教学对教学效果的影响。然后对情境教学开展的现状进行调查、分析,了解第一手情况。在此基础上,研究了有效问题情境的特点,创设有效问题情境的原则、方法以及创设问题情境的过程中需要注意的问题,最后,结合笔者一学期的情境教学实践及对比试验,,进一步从实践层面研究了情境教学对教学效果的影响。研究表明,构建良好的情境开展教学,能提高学生学习数学的的兴趣,使数学知识和数学思想更易于接受,提高学生的学习成绩和数学思维能力,培养了创新精神。同时,对教师也提出了更高的要求。更多还原

【Abstract】 Today’s society, Basic education reform carried out in full swing, Promote quality education, Cultivate innovative talents has become a top priority of education。 Competition in the21st century is a science and technology competition、Talent competition, The success or failure of education related to the rise and fall of the national team。To cultivate innovative talents, Need to cultivate awareness, The problem of consciousness is inseparable from the problem situation。The good problem situations can attract students’ attention, Positive initiative to improve learning, Make learning interesting, In the spontaneous self-inquiry learning process, Cultivate creativity。Because of Mathematical Situations so important, The new curriculum standards are given in various school teaching suggestions, Requirements to create a wealth of real-life situations to carry out teaching。And the situational teaching is carried out is not ideal, Many students still feel very painful learning mathematics, Boring。This is mainly because some teachers hold traditional education refused to discard, Weak awareness of situational teaching or situations are not the creation of a limited and reasonable to carry out teaching。In this paper, more than the status quo, First read a lot about the creation of situations related literature and theoretical knowledge, Studied at the theoretical level of situational teaching on the effectiveness of teaching, Then the status quo of of situational teaching is carried out to investigate, analyze, understand first-hand the situation。On this basis, To study the characteristics of effective problem situations, Problems that need attention in the process of creating effective problem situations, principles, methods, and the creation of problem situations, Last, The situational teaching practices combined with the author semester comparative test, Further research from a practical level of situational teaching on the effectiveness of teaching。Studies have shown that, Build a good situation to carry out teaching, Can improve student learning in mathematics interest, Mathematical knowledge and mathematical thinking is easier to accept, Improve student achievement and mathematical thinking ability, Cultivate the spirit of innovation。At the same time, Also put forward higher requirements for teachers。更多还原
