第一篇：淺談數學課后練習

淺談數學課后練習

課后的作業練習是數學教學中非常重要的一個環節，也是課堂教學的延伸。作業既是教師了解學生一種方式，也是訓練學生思維和培養學生能力的一種方式。教師在布置作業時如果不謹慎考慮，會嚴重影響學生的生理與心理健康，結果學生做得苦，教師批得累，卻達不到鞏固練習的效果。在課堂教學改革的今天，教師應從作業的主體——學生出發，讓學生想做作業、樂于做作業，從而提高學生的學習欲望。所以，我們設計作業時，既要考慮作業的趣味性、實踐性，又要注重學生能力培養，還要考慮作業的層次性。讓每個學生能夠獨立完成。

一、作業要有趣味性。教師在設計作業時，最好把數學知識編成故事、童話、游戲等形式，使學生一看到作業的內容就來勁，激發了學生的求知欲。使學生愿意做、樂于做。

二、作業要有實踐性。教師要結合有關的教學內容，聯系現實生活中的實際問題，布置有實踐性的作業，讓學生在親身實踐中去體驗所學的知識，在實踐中運用知識、盤活知識，通過實踐，使之再學習、再探索、再提高。最終培養學生解決實際問題的能力。

三、作業要有層次性。教師在布置作業時要考慮全體學生的完成度，一個班級學生的思維及能力是不同的，在布置作業時要分層行使。我認為每次全班不一定都要做一樣的作業練習，學困生可做容易點的，復雜點的可課后輔助學困生完成。

總之，課后練習是數學教學的重要組成部分，對于我們每一個教育工作者來說，在數學課堂教學時，都要深入了解每一個學生，慎重地考慮每一個教學環節。
