在实际教学中,我们不难发现有一些无效的拓展出现在音乐课堂中。主要问题是流于形式或脱离学生的实际等等。这些无效的拓展影响了教学效率,无助于学生音乐能力的提高。那么怎样的拓展才是有效的?笔者作了如下探索:一、拓展适度,主次分明一首音乐作品里面往往融合了自然、地理、人文社会等方面的知识,音乐课堂教学应在学生理解音乐本身内容的同时,将与音乐作品有关的其他知识有机融入并引导学生领会,拓展延伸的目的。但是,音乐与其他学科的拓展要适度,应该把主要精力放在音乐学习上,切不可不着边际,以免喧宾夺主、本末倒置,不要把音乐课变成综合课、思想品德课、常识课。如在上《草原巡逻兵》时,有些教师通过多媒体介绍了祖国大草原的地理位置,气候,风俗人情,接着又介绍草原上解放军的生活情况,他们是怎样巡逻的,讲述他们守护边疆,保卫祖国的崇高思想。让人感觉这不是在上音乐课,而 In actual teaching, we find it easy to find some ineffective expansions in the music class.

However, the development of music and other disciplines should be modest, and the major focus should be placed on the study of music. We must not marginalize it in order to avoid being overbearing and putting the cart before the horse. We should not turn music into integrated courses, ideological and moral courses, and common sense classes. As in the Prairie Patrol, some teachers introduced the geography, climate and customs of the prairies in the motherland through multimedia. Then they introduced the life conditions of People’s Liberation Army on the prairie. They patrolled how they guard the frontier and defend The lofty idea of ​​the motherland. People feel this is not on the music lesson, however
