摘要
当前的估算教学引起了广泛关注,存在着诸多困惑.通过调查梳理出内容理解和教学认识方面存在如下问题:本体性内容的逻辑关系认识不明确、与其它内容之间的关系认识不清、应用条件认识不足、估算结果的科学评价标准不清楚、教和学的认识模糊,教学的阶段要求不明确.针对以上问题提出了"把握估算课程价值,确保育人价值实现;正确定位估算课程内容及其教学;坚持估算的特殊教学原则;把握估算课程内容特征,采取针对性的教学策略"的解决策略和"深入研读课标及其解读,把握课程的基本要求;整体梳理估算课程内容,有序逐步实现达标"的建议.
Teaching on estimation has attracted attention widely, there is a lot of confusion in the current teaching practice. Through the investigation some problems are found in content understanding the teaching cognition: logic of the content itself is not definite, understanding of the relationship between other knowledge is not clear, the application conditions of knowledge are lack, evaluation criteria to the results of estimation is not clear, understanding on teaching and learning is fuzzyand stage requirements on teaching are not clear. Some resolution strategies proposed to some problems above are: grasping estimation instructional value to ensure the realization of the value on educating people; correcting the positioning of the estimation and estimation on teaching; adhering to the special principles about estimation on teaching; grasping estimation courses content features, targeting strategies on teaching. Some suggestion is: studying deeply curriculum standards and their interpretation, grasping the basic requirements of teaching; arranging estimates course content overall, realizating the standards orderly and progressively.
