    在“我爱我家”主题开展过程中,我们为幼儿创设了一种家的氛围,让幼儿产生爱的体验。我想,音乐活动也可以配合这一主题,丰富幼儿的情感。因此,我就想以大头儿子和小头爸爸这两个幼儿耳熟能详的动画人物为主人公,创设一个活动情景作为本次活动的载体。一方面,活动中的律动动作大部分是双人动作,如亲一亲、抱一抱、压跷跷板等,既能在日常生活中幼儿与父母身上找到痕迹,又能体现亲子感情,所以用大头儿子和小头爸爸贯穿整个活动,可以自然地激发幼儿对家人、对亲情的认知和体验。

    XX--2018学年第一学期第八周国旗下讲话稿:秋意寒勤锻炼尊敬的老师们、亲爱的同学们:大家好!今天,我国旗下讲话的题目是《秋意寒勤锻炼》。秋季的到来,给南方的天气增加了几分寒意,这个季节,没有了夏日的骄阳,正是锻炼身体的好时机。参加秋季体育活动,不仅能够锻炼身体增强体质,而且还能提高身体的抗寒能力和增强抵抗各种疾病的能力。秋季体育锻炼,由于肌肉不断收缩,呼吸加快,新陈代谢旺盛,身体产生的热量增加。同时还增强了大脑皮层的兴奋性,使体温调节中枢灵敏、准确地调节体温,提高人们的御寒能力。在锻炼中接受阳光的照射能够促进身体对钙、磷的吸收作用,有助于骨骼的生长发育。尤其对正在长身体的同学们来说,多参加户外锻炼更为重要。

    尊敬的领导、老师,亲爱的同学们:早上好!今天我发言的主题是:团结就是力量!曾经有人问闻名世界的指挥家卡拉扬:“你是如何指挥世界著名的交响乐团?”卡拉扬说:“我只强调三个音来使我的乐队变成团队。首先强调,‘起音’;起音不齐,乐曲就乱。第二个是个人的‘专业音’,不管是吹喇叭的还是打鼓的,要表现出自己专业上认为是最好的、最出色的音。第三个音则是‘团队音’,当你打出自己的专业音之后,还要考虑到整体,是不是会成为干扰别人的音。”卡拉扬说的多好呀!我们的学校,我们的班级,我们的学习,我们的生活不也都需要这样的团队精神吗?如果把我们的班级比作一只乐队,那么共同的集体目标就是我们的“起音”,发挥每个人的才能是我们的“专业音”,同心协力,团结奋斗就是我们的“团队音”。

    4、种群数量变化的其他类型我结合“种群数量下降”这个知识点对学生进行寓教。现今的自然界,许多野生生物种群的数量都在下降,为什么呢?我提供了世界人口近2000年的种群增长曲线,一切都在不言而喻中。现今社会的主题是呼吁建立和谐社会,作为生物老师,我想它不应该仅仅指人与人之间的和谐,也不应该仅仅指人与社会之间的和谐,它更应该昭示着人与自然之间的和谐,人类只有学会与自然和谐相处,才能在生物圈中享受最大的幸福。6、小结课程在实验的大背景下展开,也在实验的背景中结束,这里可以呈现出一个完整的探究思路。同时,学生思考如何实现多种预期过程,相当于对本课进行小结。五、效果预测课堂上选取的内容基于学生的生活体验,创设的情境能激发学生的兴趣,设置的问题符合学生的认知水平,有助于学生能力的提高,教学目标可以基本实现。
