一个人的能力包括多方面,如记忆能力、分析能力等等。笔者在多年的教学实践中发现,多数学生都有较强的记忆力,而却缺乏对问题的分析能力,那么,在生物学教学中如何培养这种能力呢? 一、教师授课深适:教师讲课照本宣科,学生对有些知识也只能是机械地死记硬背,要克服这种弊病,教师授课必须深造。例如,高中《生物》（必修本）第11页,关于无机盐在细胞中的重要作用提到,“哺乳动物的血液中必须含有一定量的钙盐,如果血液中钙益的含量太低,这种动物就会出现抽搐”,这其中的道理要给学生讲清楚.血液中的钙能降低神经系统和骨胳肌的兴奋性,当血钙含量过低时,神经系统和骨胳肌的活动就会加强,使肌肉不停地收缩和舒张,
One’s ability includes many aspects, such as memory ability, analysis ability and so on. The author found in many years of teaching practice that most students have strong memory, but they lack the ability to analyze problems. How to cultivate this ability in biology teaching? First, the teacher teaching is appropriate: the teacher lectures According to the textbook, students can only mechanically memorize certain knowledge. To overcome this problem, teachers must teach. For example, on the 11th page of High School “Biology” (required edition), on the important role of inorganic salts in cells, it is mentioned that “mammalian blood must contain a certain amount of calcium, if the calcium content in the blood is too low, “This kind of animal will have convulsions.” The reason for this is to make it clear to students. The calcium in the blood can reduce the excitability of the nervous system and skeletal muscles. When the calcium content in the blood is too low, the nervous system and the skeletal muscles Activities will be strengthened to keep the muscles contracted and relaxed.
