    人教版高中政治必修1影響價格的因素說課稿

    第一部分:說教材我將從本框題的地位、教學(xué)目標及教學(xué)重難點等方面進行闡述。首先,本框題在教材知識體系中的地位:《影響價格的因素》是人教版教材高一政治必修第一單元第二課的第一框題。本框主要給學(xué)生介紹引起商品價格變化的因素,使學(xué)生通過學(xué)習(xí)能夠明確日常經(jīng)濟生活中價格變動的原因。本框既是對前一課內(nèi)容的承接又是下框內(nèi)容得以展開的基礎(chǔ),也就是說,本框在本單元學(xué)習(xí)中起著承上啟下的作用。其次,教學(xué)目標。根據(jù)課程標準的要求和學(xué)生的實際情況,我將確定以下的教學(xué)目標:(1)知識目標歸納影響價格的因素,理解價值決定價格、社會必要勞動時間決定價值量以及勞動生產(chǎn)率與商品價值量的關(guān)系,明確價值規(guī)律的基本內(nèi)容和表現(xiàn)形式。(2)能力目標培養(yǎng)學(xué)生透過現(xiàn)象分析事物本質(zhì)的能力;增強學(xué)生的競爭意識,提高參與經(jīng)濟生活的能力。

    回歸生活:近幾年,我國市場上豬肉價格在不斷地波動。請智囊團商議:我們集團如何才能避免重蹈“張老漢”的覆轍?學(xué)生活動:思考、發(fā)言、群策群力。教師鼓勵學(xué)生從多角度分析,找出解決問題的不同方法。教師點撥:在豬肉價格波動較大時,我們除了調(diào)節(jié)生產(chǎn)規(guī)模,還可以采用引進新品種、加強科學(xué)管理等手段來提高勞動生產(chǎn)率,從而在價格競爭中更具優(yōu)勢。同時,我們要在激烈的市場競爭中站穩(wěn)腳跟,還必須以市場為導(dǎo)向,生產(chǎn)適銷對路的高質(zhì)量產(chǎn)品,做到“人無我有,人有我優(yōu),人優(yōu)我轉(zhuǎn)”。教師引導(dǎo)學(xué)生分析:價格變動對生產(chǎn)規(guī)模的調(diào)節(jié)、對勞動生產(chǎn)率的提高及促使企業(yè)生產(chǎn)適銷對路的高質(zhì)量產(chǎn)品,就是在價格、供求關(guān)系及市場競爭的刺激下,價值規(guī)律發(fā)揮“棒子”(調(diào)節(jié)資源配置)、“鞭子”(鞭策個別勞動生產(chǎn)率的提高)及“篩子”(優(yōu)勝劣汰)作用的結(jié)果,從而將本節(jié)課的內(nèi)容與第一框題有機聯(lián)系在一起,幫助學(xué)生從不同角度更深刻的理解價值規(guī)律的作用。
