      化學學科的教學反思

      教學反思 時間:2019-07-04 我要投稿
      【www.51cxty.com - 教學反思】

        反思是教師以自己的職業活動為思考對象,對自己在職業中所做出的行為以及由此所產生的結果進行審視和分析的過程。教學反思被認為是教師專業發展和自我成長的核心因素。

        新課程非常強調教師的教學反思,按教學的進程,教學反思分為教學前,教學中,教學后三個階段。在實際教學中,我通過在三個不同階段對教材的理解,教學目標的制定,教學方法的設計等多方面進行不斷的思考和更新,使我在理論和實踐經驗方面都有了很大提高。

        一、教學前反思:

        在教學前進行反思,能使教學成為一種自覺的實踐。在以往的教學經驗中,教師大多關注教學后的反思,忽視或不做教學前的反思。其實教師在教學前對自己的教案及設計思路進行反思,不僅是教師對自己教學設計的再次查缺補漏,吸收和內化的過程,更是教師關注學生,體現教學以學生為本這一理念的過程。

        在本次授課中,我第一步是讓學生回憶什么是鑒別,以及鑒別的依據是什么,進而提出物質在溶液中存在的微粒,使學生把鑒別的實質理解清楚,即物質的鑒別歸根結底的是離子的鑒別。這樣的設計使培養了學生通過現象看本質的能力。

        在接下來的教學設計中,我設計了分組討論,目的是培養學生的協作精神。還安排的學生實驗,以培養學生的動手能力。另外在一道題中安排多種解法,拓展了學生的思維。

        在接下來的練習中我采用由易到難的手法,符合學生的思維發展。

        上課前,我認真地對教學思路,教學方法的設計,教學手段的應用及學生的年齡特點,在課上可能有的反應做了充分的反思。

        經過課前的反思與調整,教學內容及方法更適合學生,更符合學生的認知規律和心理特點,從而使學生真正成為學習的主體。

        二、教學中反思:

        在教學中進行反思,即及時,自動地在行動過程中反思,這種反思能使教學高質高效地進行。課堂教學實踐中,教師要時刻關注學生的學習過程,關注所使用的方法和手段以及達到的效果,捕捉教學中的靈感,及時調整設計思路和方法,使課堂教學效果達到最佳。

        在前面的課堂教學實踐中,當學生爭先恐后地展示自己所設計的實驗方案,并要求用實驗驗證,而且很多學生積極參與討論,來評價其他同學的設計方案。同時在教學中根據學生的思路和熱情,我及時調整自己的教案,一起到更好的引導效果,實現學生為主體,教師為主導的教學理念。在我精心設計的問題的引導下,學生思路清晰了,課前預期的目的基本達到。

        根據課堂上的具體情況,經過我適時地調整,創新教學內容和方法,使學生能夠結合實際高頻率地運用知識,解決問題的能力,更好的提高了教學質量和教學效果。

        三、教學后反思:

        教學后的反思——有批判地在行動結束后進行反思,這種反思能使教學經驗理論化。在課堂教學實踐后及時反思,不僅能使教師直觀,具體地總結教學中的長處,發現問題,找出原因及解決問題的辦法,再次研究教材和學生,優化教學方法和手段,豐富自己的教學經驗;而且是將實踐經驗系統化,理論化的過程,有利于提高教學水平,使教師認識能上升到一個新的理論高度。

        通過反思《物質鑒別的復習課》,對這一課進行全面反思后,我認識到要善于處理好教學中知識傳授與能力培養的關系,巧妙地創設能引導學生主動參與的活動及情境,讓學生在實踐中學習,才能不斷地激發學生的學習積極性與主動性,既培養學生的學習興趣,又培養學生思維能力,想象力和創新精神,使每個學生的身心都能得到充分的發展。

        經過一次又一次的反思——提高——再反思——再提高的過程,我受益非淺,也更加深刻地認識到了在教學中及時反思的重要性和必要性,它會使我逐漸形成自我反思的意識和自我監控的能力。在今后的教學中,我會通過不斷地反思來提高自己的教學水平和創新能力。
