在体育教学中,经常有这种现象发生,有的学生为了快速掌握某一动作技能,在一定时间内多次重复练习,反而是付出的劳动代价越多,其练习效率愈益递减。这一现象在教育心理学上称之为“报酬递减”。产生这一现象的原因与当时的练习情境、练习方法、练习时间、练习心向等因素有关。因此,在教学中可以采取以下几种方法加以克服: 一、改变练习情境在教学中如果是因场地器材、学生相互干扰或教师要求过高等,造成“报酬递减”现象,要及时改变这一不良的练习情境。例如:在双杠分腿坐教学中,首先要建立本体对器械的感觉能力,适当降低器材的高度;同时加强保护帮助,减少学生 In physical education, this phenomenon often occurs. Some students in order to quickly master a certain movement skill, repeatedly practice in a certain period of time. Instead, the more labor cost, the more and more practice efficiency declines. This phenomenon is called “diminishing returns” in educational psychology. The reason for this phenomenon is related to the current practice situation, practice methods, practice time, practice heart and other factors. Therefore, in teaching can be taken to overcome the following methods: First, to change the practice situation in the teaching if it is due to venues and equipment, students interfere with each other or teachers too high, resulting in “diminishing returns” phenomenon, to promptly change the bad Practice situations. For example: in the parallel bars sit leg teaching, we must first establish the body’s ability to sense the equipment, appropriately reduce the height of the equipment; at the same time to strengthen the protection of help to reduce students
