1、3、继续指导、引导学生学习运用假设,分析事物之间的因果关系,注重实验中的观察能力、采集数据,并对实验结果做出自己的解释,学习建立解释模型,以验证自己的假设。4、培养学生利用书籍、网络、报刊等查阅资料,搜集整理信息的能力。(三)情感态度与价值观1、保持和发展学生对周围世界的好奇心与求知欲,形成大胆细心、注重数据、敢于质疑的科学态度和爱科学、爱家乡、爱祖国的情感。2、培养学生亲近自然、欣赏自然、珍爱生命的意识,积极参与资源和环境的保护,关心现代科技的发展,使学生形成人与自然和谐相处的意识。3、培养学生的合作和交流的意识,敢于争辩的胆识,同时学会尊重他人意见,合理的表达自己的见解。四、教学重点:1.
2、指导学生大胆利用已有的经验对一些事物和现象进行有根据的推测,作出假设性解释。比如推测小电动机转动原因,煤的成因,根据动植物的形态特征推测它们生活的环境等。2.指导学生认真收集数据,意识到要尊重数据,用严谨的态度得出结论,如研究杠杆尺的实验,研究电磁铁磁力大小的实验。3.本册中的很多内容适于动手操作,材料简单易得,要给学生创造实践的机会,保证学生能真正地动起手来进行探究学习,这更能促进学生思维的深度参与。4.建立能量概念,认识生物的多样性是在学生三年学习的积累上进行的,要注意充分利用他们原有的知识,并帮助他们梳理、提升,形成概括性更高的科学概念。五、教学措施 1、解学生对所学科学问题的初始想法,
3、特别是一些概念理解过程中出现的想法。2、指导学生反复进行控制变量的实验。(控制变量实验要加以指导)3、引导学生在观察和实验的过程中做好记录。4、引导学生用准确、恰当的词语描述观察到的事实和现象。5、引导学生对观察和实验结果进行整理和加工,形成正确的解释。后进生的指导:在差生转化方面,把握这部分学生科学学习的特点,因势利导。用丰富多彩的亲历活动充实教学过程。还是要狠下工夫监督学生去完成课堂作业与课后作业,课后做到个别辅导,并参与实验室一起整理,尽量减少差生的数量。做好与家长的沟通工作,与班主任多做交流,大家齐心协力完成三年级的科学教学任务。优秀生学生培养:1、悉心地引导学生的科学学习活动。纂写科
