教学是一个复杂的过程,创造性教学更非易事。笔者在初中《生理卫生》教学中,根据初三学生智力发育的特点,逐步改善自己的教学方法,取得了较好的效果。 一、教学课题的设计 在教学过程中,每堂课都应可一个主要内容或重点内容。笔者认为,为了在教学中突出主题或把重点讲解清楚,课题的设计很有必要。优秀的课题对一堂课起到画龙点睛的作用,使教学产生意想不到的良好效果。在教学中,笔者曾设计了一些课题。例如以“了解自身,预防疾病──学好《生理卫生》”为题引出（绪论）,以“人体的天然屏障──皮肤”引出“皮肤”以“生命在于运动”或“流水不腐,户枢不蠹”等为题引出“运动系统”。总之,课题的设计,应以揭示课文的中心为准。要求课题形象、幽默、概括、富有启发性。我发现,课题教学,不仅能突出教学的重点,给学生一个新课知识的轮廓,同时,也增强了一堂课本身的完整性。 二、教学内容的形象化和具体化 初中学生抽象思维能力较弱。在教学过程中,教师应尽量将一些抽象的知识具体化,将一些复杂的问题简化,而具体化和简单化的有效方法就是善于运用比喻。笔者在教学中体会到,一个好的比喻,对教学有事半功倍之 Teaching is a complicated process, and creative teaching is even more difficult. In the junior high school “physiological health” teaching, the author gradually improved his teaching methods according to the characteristics of the mental development of junior high school students and achieved good results. First, the design of teaching topics In the teaching process, each class should be able to provide a main content or key content. The author believes that the design of the project is necessary in order to highlight topics in the teaching or explain the key points clearly. Excellent topics play a crucial role in the teaching of a class, so that teaching has unexpected and good results. In teaching, the author has designed some topics. For example, citing “know about oneself, prevent disease—learning “physiological hygiene”” (introduction), using “natural barrier of human body—skin” to lead “skin” to “life is in motion” or “water is not rot, households “The pivot does not squat” and other topics lead to “motion system.” In short, the design of the topic should be based on the center of the text. Asks the subject image, humor, generalization, and enlightening. I found that subject teaching can not only highlight the focus of teaching, give students a profile of new class knowledge, but also enhance the integrity of a class itself. Second, the visualization of teaching content and concrete junior high school students abstract thinking ability is weak. In the process of teaching, teachers should try to concretize some abstract knowledge and simplify some complex issues. The effective method of concreteness and simplification is to be good at using metaphors. The author experienced in the teaching, a good metaphor, has a double effect on teaching
