在生物教学的整个过程中,综合复习阶段是必不可少的教学环节。而统计这一环节中的学生成绩变化,发现这样一条曲线:先是上升较快,接着出现一个较为平稳的“高原期”,之后又有上升趋势。上述曲线中平稳的“高原现象”是怎样出现的呢?本文就此谈谈粗浅看法。所谓“高原现象”,是指“在技能形成中,练习中期往往出现进步的暂时停顿现象”。①过去一般认为“高原现象”并不具有普遍性。现在学者认为,人类的任何学习都要经过这样过程:“开始阶段——迅速进步阶段——高原阶段——克服高原阶段”。② In the whole process of biology teaching, the comprehensive review stage is an indispensable teaching link. However, statistics on the changes in students’ grades in this session found a curve that firstly increased rapidly followed by a relatively stable “plateau period” and then an upward trend. The smooth curve of the “plateau phenomenon” is how it appeared? This article to talk about the superficial view. The so-called “plateau phenomenon” refers to “the temporary formation of skills in the mid-practice often appear to stop the phenomenon of progress.” ① In the past generally considered “plateau phenomenon” is not universal. Now scholars believe that any learning of human beings goes through the process of “the beginning phase - the rapid progress phase - the plateau phase - the overcoming of the plateau phase”. ②
