【摘要】：呼吸作用是初中科學(xué)教學(xué)的重難點(diǎn),也是初中生物學(xué)領(lǐng)域的核心。呼吸是我們?nèi)祟愝^熟悉的生命活動(dòng),而呼吸作用在農(nóng)業(yè)、食品、水果保鮮等領(lǐng)域也有著廣泛的應(yīng)用。正因如此,學(xué)生對(duì)這一領(lǐng)域的學(xué)習(xí)會(huì)產(chǎn)生巨大的共鳴和興趣。因而本研究將對(duì)呼吸與呼吸作用專題進(jìn)行教學(xué)設(shè)計(jì)研究。本次教學(xué)設(shè)計(jì)以建構(gòu)主義理念為框架,引入探究學(xué)習(xí)、合作學(xué)習(xí)和自主學(xué)習(xí)的學(xué)習(xí)模式,希望讓學(xué)生真正觸摸到科學(xué)的本質(zhì),讓他們從心底里愛(ài)上科學(xué),時(shí)時(shí)刻刻想著運(yùn)用科學(xué)。本研究主要采用了文獻(xiàn)研究法和實(shí)驗(yàn)法。其中,實(shí)驗(yàn)的開(kāi)展將是教學(xué)中的中心環(huán)節(jié)。為了配合教學(xué),筆者設(shè)計(jì)了新的實(shí)驗(yàn)(裝置),包括了新呼吸模型Ⅰ、新呼吸模型Ⅱ、新氣體交換實(shí)驗(yàn)Ⅰ、新氣體交換實(shí)驗(yàn)Ⅱ、探究植物呼吸作用的新實(shí)驗(yàn)和探究酵母菌發(fā)酵的新實(shí)驗(yàn)。另外,筆者為這些新的實(shí)驗(yàn)開(kāi)發(fā)出配套的探究活動(dòng)。有了前期的準(zhǔn)備后,筆者對(duì)本專題進(jìn)行教學(xué)設(shè)計(jì),計(jì)劃6個(gè)課時(shí)。在這些教學(xué)設(shè)計(jì)中,每一課時(shí)都分別有一個(gè)不同的問(wèn)題情境,在實(shí)驗(yàn)前還有幾個(gè)“熱身”的探究活動(dòng),還有許多豐富多彩的課堂活動(dòng)。而且,在課結(jié)束后,學(xué)生還可以繼續(xù)探究。最后,筆者從實(shí)驗(yàn)設(shè)計(jì)和教學(xué)設(shè)計(jì)兩個(gè)方面對(duì)本次研究中出現(xiàn)的問(wèn)題和不足之處進(jìn)行了總結(jié)與反思。
[Abstract]:Respiration is the most important and difficult part in junior high school science teaching, and it is also the core of biology in junior high school. Respiration is a familiar activity of human life, and respiration is widely used in agriculture, food, fruit preservation and other fields. For this reason, students in this field of learning will have a huge resonance and interest. Therefore, this study will carry on the teaching design research to the respiration and the respiration action topic. This teaching design takes the constructivism idea as the frame, introduces the inquiry study, the cooperation study and the independent study pattern, hoped that lets the student truly touch the science essence, let them fall in love with the science from the bottom of the heart. Always thinking about the use of science. This research mainly adopts the literature research method and the experimental method. Among them, the development of experiment will be the central link in teaching. In order to cooperate with the teaching, the author designed a new experiment (apparatus), including the new breathing model 鈪，
