在数学教学中普遍利用“题海战术”来提高学生的解题能力及速度.这在很大程度上是以牺牲学生的大量时间和精力为代价,因为这些时间学生原本可以用来发展其它能力,参加其他活动及用来休息调整体力,这显然是不妥当的.同时,与现在的素质教育也是不相容的, 与当前的“减负”也不相符. In mathematics teaching, the “sea tactics” are commonly used to improve students’ problem-solving abilities and speeds. This is largely at the expense of the students’ time and energy, because these students could be used to develop other abilities. It is obviously inappropriate to participate in other activities and to rest and adjust physical strength. At the same time, it is incompatible with the current quality education, and it is also inconsistent with the current “burden reduction”.
