【摘要】:呼吸作用是初中科学教学的重难点,也是初中生物学领域的核心。呼吸是我们人类较熟悉的生命活动,而呼吸作用在农业、食品、水果保鲜等领域也有着广泛的应用。正因如此,学生对这一领域的学习会产生巨大的共鸣和兴趣。因而本研究将对呼吸与呼吸作用专题进行教学设计研究。本次教学设计以建构主义理念为框架,引入探究学习、合作学习和自主学习的学习模式,希望让学生真正触摸到科学的本质,让他们从心底里爱上科学,时时刻刻想着运用科学。本研究主要采用了文献研究法和实验法。其中,实验的开展将是教学中的中心环节。为了配合教学,笔者设计了新的实验(装置),包括了新呼吸模型Ⅰ、新呼吸模型Ⅱ、新气体交换实验Ⅰ、新气体交换实验Ⅱ、探究植物呼吸作用的新实验和探究酵母菌发酵的新实验。另外,笔者为这些新的实验开发出配套的探究活动。有了前期的准备后,笔者对本专题进行教学设计,计划6个课时。在这些教学设计中,每一课时都分别有一个不同的问题情境,在实验前还有几个“热身”的探究活动,还有许多丰富多彩的课堂活动。而且,在课结束后,学生还可以继续探究。最后,笔者从实验设计和教学设计两个方面对本次研究中出现的问题和不足之处进行了总结与反思。
[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,
