I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!?

紧接着是升记号的认识。在这里我把升记号介绍给学生，教师先用电子琴演奏没有升记号的乐句，再演奏有升记号的乐句，学生听一听那一个音有变化。然后教师再分别把单独的有变化的一个音拿出来进行比较，最后用键盘图在幻灯片上展示。使学生更直观的去听去感受，使学生听觉与视觉互补。增强学生的参与意识，使复杂乏味枯燥的音乐知识变的趣味化，生动化，通过师生的共同参与，更加拉近了教师与学生的距离。最后是编创与活动.由于这首歌是以环保为主题，所以我用音乐与环境保护有机结合的融合，从而进行德育渗透，通过生生合作、和自主探究的方式来进行编创歌词。最后让学生用载歌载舞的形式表现歌曲.依托音乐本身的魅力培养学生主动学习，合作意识，探究精神，从目标的提出到过程的安排，学习方法的确定乃至学习成果的呈现，都让学生有更大的自主性，更多的实践性，更浓的创造性。
