    本課是高中數(shù)學第一章第4節(jié),充要條件是中學數(shù)學中最重要的數(shù)學概念之一, 它主要討論了命題的條件與結論之間的邏輯關系,目的是為今后的數(shù)學學習特別是數(shù)學推理的學習打下基礎。從學生學習的角度看,與舊教材相比,教學時間的前置,造成學生在學習充要條件這一概念時的知識儲備不夠豐富,邏輯思維能力的訓練不夠充分,這也為教師的教學帶來一定的困難.“充要條件”這一節(jié)介紹了充分條件,必要條件和充要條件三個概念,由于這些概念比較抽象,中學生不易理解,用它們?nèi)ソ鉀Q具體問題則更為困難,因此”充要條件”的教學成為中學數(shù)學的難點之一,而必要條件的定義又是本節(jié)內(nèi)容的難點.A.正確理解充分不必要條件、必要不充分條件、充要條件的概念;B.會判斷命題的充分條件、必要條件、充要條件.C.通過學習,使學生明白對條件的判定應該歸結為判斷命題的真假.D.在觀察和思考中,在解題和證明題中,培養(yǎng)學生思維能力的嚴密性品質(zhì).
