2016年10月22日托福考试真题及答案(附答案)(3)
4.学生情况分析
1、整体学习状况:三年级学生整体对科学学习兴趣较高,学习比较认真,但缺乏灵活性。他们普遍习惯于常规的课堂学习模式,不善于在生活中尝试独立获取知识和灵活运用知识。因此,学生对基础知识的掌握往往只停留在理解上,理解不是很深,应用能力较差。
2、已有的知识和经验:从课外书籍中获得的科学知识比较丰富,但科学探究能力比较弱。家长和部分老师注重语文和数学的教学,使学生没有太多的时间和机会接触大自然,也没有得到大人和老师及时周到的指导,使学生在观察、实验方面做得不好,调查和其他实践活动。获得知识教科版三年级科学上册表格式教案,发展能力,培养思想和情感。
第四章:教科书版三年级第二册科学教学计划精选
1.教科书分析
新三年级《科学》第二卷是在三年级第一卷的基础上编写的。小学三年级第一卷是科学教材的起始卷。所选教学内容以学生的“系统观察活动”为主线。例如,在教学内容中设计了“观察大树”、“寻找小动物”等活动。作为这一线索的延续,三年级第二卷的主题确定为“观察物质特性和变化”。《我们的身体》、《动物王国》等五个单元。
第一单元主要引导学生探索生活中的相关现象,体验科学探究,体验成功的喜悦。第二单元主要让学生通过阅读大量资料,对太阳的大致情况有一个初步的了解。第三单元主要引导学生从身边熟悉的电器入手,结合已有的生活经历,通过观察、设计实验等方式,揭开与雨滴相关的相关研究。第四部分从自己的身体开始,引导学生探索神秘而新颖的生命领域——人体。第五单元以学生对几种常见动物的认识为基础,逐层展开,让学生体验科学探究的过程。
学生分析
1.三年级孩子想象力丰富,思维活跃,天生的好奇心是科学学习的起点。他们对花、鸟、鱼、虫、日月星辰的好奇,只要引导得当,就能转化为强烈的求知欲和学习行为。
2、通过一个学期的“理科”学习,学生已经对“理科”课程有了一定的了解,知道了理科课是由一项活动组成的,这让他们很喜欢。但他们往往无法有意识地为上课做准备。
3.虽然经过一个学期的科学研究,学生已经具备了一定的观察能力,但他们的观察和思考能力有待提高。学生往往只看事物的表面,不知道事物的内部,很难把握事物之间的相互作用。连接。
4. 对实验感兴趣,但很容易停留在表面而不深入研究。
5.受传统观念影响,学生缺乏对科学学科重要性的认识。
三、教学要求及评价
1. 师生可以准备足够的探究活动材料,如薄而透明的塑料袋、水槽、玻璃杯、废纸、气泵等。教师的指导应该能够使学生产生强烈的好奇心和积极的探索欲望。教师要保证学生的每一次探究活动都有足够的时间,让学生的感受、思考和表达得到更充分的发挥。通过探索活动,学生知道空气是一种透明的物质,没有一定的开关和体积,但有质量;了解固体、气体和液体之间的主要区别;知道空气是可以压缩的,压缩空气有弹性等;同时,潜移默化地认识到,借助可见的物质媒介,可以发现和研究不可见的物质;
2、通过体验种植、栽培辣椒的活动,了解植物的根、茎、叶、花、果实和种子,了解植物的生长过程;知道一粒种子可以发育成一株植物并再次结出多颗种子。,了解植物生命周期的含义。在活动过程中,学生可以理解珍惜生命的意义,懂得爱护花草树木,学会连续多方地观察事物,提高科学探究能力,学会与他人合作; 让学生在活动过程中知道如何培养植物的正确方法;学习通过数据、图片、语言描述等方式交流自己的观察结果;用整理信息的方法,发现事物变化的简单规律。
3. In the course of classroom teaching, students are willing to participate in a series of observation and research activities in various forms, gain experience in various observation and research activities, and be able to communicate their own observation and research findings in groups or classes;
4. Guide students to start by observing the substances around them, cultivate their careful observation habits and attitudes in the process of activities, infiltrate scientific ideas and methods, and guide them to conduct scientific observations and experiments, so that they can experience the joy of scientific inquiry, and Continue to maintain and develop their hobbies and hobbies to explore things around them.
Four, specific measures to improve teaching
1. Use the new curriculum concept to "use teaching materials" instead of "teaching teaching materials".
2. Carefully study the teaching materials, pay attention to the design of typical scientific exploration activities for students, and do a good job in preparation before class. Use a variety of evaluation methods to stimulate students' interest in inquiry.
3. Encourage students to make bold guesses and make multiple assumptions and predictions about the outcome of a problem. Educate students to think about an action plan, including developing steps, choosing an approach, and envisioning safety measures, before embarking on a problem-solving process.
4. Pay attention to collecting first-hand information, and teach students to observe, measure, experiment, record, count and make statistical charts and other methods.
5. Organize the post-exploration discussion and guide students to listen carefully to the opinions of others. Pay attention to instructing students to draw their own conclusions, and teachers should not impose their own opinions on students.
6. Make full use of teaching aids, wall charts, and audio-visual teaching materials for intuitive teaching. In particular, each observation and awareness activity should be organized well, so that students can experience and experience each activity in person.
7. Give full play to the characteristics of extensive and close connection between subject knowledge and real life. Pay attention to guide students to use knowledge to solve problems, especially to solve practical problems that are closely related to students, so that students can experience the value of learning science.
