利用自然物教學,特別是利用生物能够大大地使學生易於懂得米丘林生物學的基本原理。提供实驗結果或提供以後作觀察和作結論用的材料的生物的陳列,能產生很大的教學效果,使學生的認識能够具體化,變得深刻得多。可是,怎樣利用生物尤其是植物試驗教學,特別是在冬季時期應該怎樣做,目前在教學法文獻中還很少說明。 The use of natural things, especially the use of living things, can greatly enhance students’ ability to understand the basic principles of Michurin’s biology. The display of living organisms that provide experimental results or provide material for later observation and conclusion can yield great teaching effects and make students’ perceptions more specific and profound. However, how to make use of biology, especially plant experiment teaching, especially how to do it during the winter period, is rarely described in pedagogy literature at present.
