测出实验结束后三组被试的数学成绩,比较三组被试数学成绩的平均数,看是否有差异,采用单因素方差分析(或者F检验),如果有差异,说明三种教学方法对数学教学效果产生了不同影响。
英语面试
1,你喜欢的电视节目
my favorite reality Tv show is the impossible game.The Tv program has six famous male stars of china to take part in, the six men are Huanglei, Huangbo, Sunhonglei, Zhangyixing,Luozhixiang and Wangxun.It is very exciting and interesting because the six men should finish the impossible tasks that they have never done before.The tasks need people's intelligence, strong body and courage.I like Huanglei the most, because he is the most clever.I also like sunhonglei and huangbo, because they seem selfish, in fact they care others very much.and zhangyixing is the member of EXO, he is very handsome and popular with girls.Luozhixiang is very funny, I like him because where he is where the happiness is.Wangxun is always cheated, but he is still kind to others.At the beginning I think it's an entertainment show, and later I find it is of educational significance.From the program I learn a lot, I hope I can learn to challenge myself from the six men, I wish I can overcome my limitation and be more kind to others.2、喜欢的音乐
I like pop music There are many different kind of musics, classic, electric, country and blue。Among all these, pop music is my favorite。I love pop music because they are always fresh and always new。Every time you get tired about one pop song, there will always be a new one waiting for you to listen。Also, I love dancing with pop music which makes me feel young。Whenever I feel upset or tired, pop music will cheer me up with they beautiful rhyme and teach me how to live my life in a right way。Pop music is the soul of youth and it goes on forever。
3、喜欢的网站 I like surfing on the Internet.Although there are lots of websites, I like the CoCo English Learning website most.It is useful for me to learn English.For-example, there are lots of English songs.I can improve my English by listening to English songs.Also, I can do some tests to check what I have learned.It is also interesting.I can make friends who like English either by it.4、喜欢团队合作还是个人
Team Work.Team work is very important in our work.It is quite often that one is not able to carry out a job by itself.He needs more people to complete it together.We can say some importance jobs could not be done without teamwork.For example,in a football match,very member plays a different role which is important,all members must cooperate with each other to fight against the opponent team.They can only win the match when they do good teamwork,or they will be defeated.China has an old saying,“Unity is strength”,which means the importance of teamwork.5.网上购物
Whenit comes to online shopping, different people holds different ideas towards it.Some people seem extremely enjoy the way of buying things online because theyfeel online shopping is so convenient.Some just don‟t believe that they can buygood quality commodities from Internet.As far as I‟m concerned, I think onlineshopping creates lots of benefits to people.People buy commodities by Internet notonly because it saves us time, but also, we can save lots of money.buying things online is a way of saving time.Inconclusion, shopping online is a convenient, time-saving and money saving way.6、分数重要还是能力重要 interpersonal relationships in the University, compared to learning, a little is not important;2 interpersonal relationship is based on the value of the potential exchange, a person of no value, do not talk about interpersonal relationships;3 learning is not just learning professional knowledge, learning without thinking of the people, also do not talk about the value of.If you want to become a man of value, it must be in learning at the same time, diligent in thinking, diligent summary.7、自己的兴趣爱好 I have many hobbies,such as listening to music,reading,running andso on.As we all known,listening to music is a good way to coordinate our mood.Therefore,I enjoy listening to music,which can make me feel very happy.Moreover,I like reading very much.Reading makes a man.I have read the article whose name is „Of Studies‟ that was written by Bacon.Hesaid that studies serve for delight,for ornament and for ability.So we can not stop learning.In other words,never too old to learn.In addition,it is necessary to do exercise regularly.I love running,because it has great effects on my health.In a word,my hobbies have positive influences on my body and soul.8、介绍家乡
Luoyang, as is known to us all, is the capital of thirteen dynasties, which is located in the west of Henan Province.The climate in Luoyang is pretty good.In summer, it won't be too hot.What's more it won't be much too cold in winter.Luoyang is a historical city, so there are so many scenic sites, such as Longmen Grottoes(Shiku), White Horse(Baima)Temple, and other beautiful scenery in Luanchuan.I think you must know this sentence 'Luoyang's peony is the best in the world'.So why not come to my hometown to see the peonies next year, and at that time I will show you around my hometown, besides, you will be taken to Laocheng, and I must treat you with lots of characteristic snacks.My hometown, Luoyang, is an amazing city and I love it so much.9、难忘的经历
An unforgettable thing I still remember the first day when I went to school.I was very shy.I sat beside my desk and did not say a word.Many boys and girls wanted me to play with them.But I was too afraid to move.Tears came to my eyes.Just then a beautiful woman came to me.She told me that she was my teacher Miss Yang.She talked with me quietly and told funny stories to me.We laughed happily and I did not feel afraid any more.She was so kind that I thought she was just like my mother.From then on ,I made up my mind to be a teacher like her when I grew up!
10、对家庭教育和对学校教育的看法
I personally think that family is more important than school education: One, in the child's growth path, family education is more important than school education, father education and mother education equally important.Second, family education with children from birth to, growth until the founding family.Family education don't in school education, the influence on children is subtle.Outlook on life, values, ethics, aesthetic view, mode of thinking, habits, behave as will give a greater impact;in the education of family education financial in family life is full of strong affection and the individual teaching way.11、喜欢的电影
My favorite cartoon film is “Kung Fu Panda”.Because it's very funny and interesting.The story was great and the background was beautiful, it really felt like an ancient Chinese city.So many people like it.In this cartoon movie the character who I most like is the panda Arab League valuable.Because it not only unusual lovable and annoys the human to like, moreover is this cartoon movie's lead.But I did not deny that other roles also very much annoy the affection, for example tigress(Angelina Jolie), viper(Lucy Liu), praying mantis(Seth Rogen), hoist crane(David cross)and monkey(Jackie Chan).I from this cartoon movie middle school: Each people have the merit and the shortcoming, perhaps you only know your shortcoming, so long as but you look diligently, also will discover that oneself will have the merit.12、城市规划
With industries and business developing quickly, the number of trees in many big cities has dramatically reduces.Efforts are being made to prevent people from cutting more trees.But a lot of trees are being destroyed by people who have never thought of the importance of green plants.Making cities greener has many advantages.First, it can make our air cleaner.Some researchers have proved that trees can reduce the amount of carbon dioxide in the atmosphere through absorption.Second, it can make our cities more beautiful.With trees and flowers everywhere, living conditions can be improved.Finally, it can produce timber----an effective way to solve the problems of limited supply of natural resources.Making our cities greener requires nationwide efforts.People in every field should not only know about the importance of keeping the quality of urban environment, but also take common action to plant more trees and flowers so as to improve our living conditions.13、二胎政策
First of all, two-child policy is the gift for some only child.For some families, maybe the parents are only child and they also can have only child.Put aside the loneliness of their child, when their child grows up and they grow older, their child marry with an only child girl accidentally, the burden on their child and his wife is unimaginable heavy.Their child and his wife have to take care of two old couples.Usually, a young couple looking after an old couple is a little difficult;if the pressure increasing twice, how can they stand it.But if their parents have two children, they can share the burden of taking care of their parents.It would be much better.首先,二胎政策对于一些独生子女来说是天赐的礼物。对于一些家庭来说,也许父母都是独生子女,而他们也只生一个孩子。抛开孩子的孤独不说,当他们的孩子长大了,而他们也变老了,他们的孩子又和一个独生子女结婚,这样的话,压在他们孩子和孩子妻子肩上的压力是不可想象的。他们的孩子和他的妻子不得不照顾两对老人。通常,一对年轻的夫妇照顾一对老人就有点难了;如果压力增加了一倍,他们怎么能忍受呢。但是如果他们的父母有两个孩子,他们就能分享照顾父母的压力。这样会比较好。
14、关于明星
Nowadays, star-worshiping is popular among teenagers, especially many university students.Why? When it comes to the symptoms of worshiping a star, the main factor I‟d like to mention is imitation.With a blind love for their idols, teenagers firmly believe that their choices are the best.As a result, the stars‟ clothes, hairstyles and hobbies, as well as their behaviors in public, are closely observed or followed, though, to some extent, they may be considered improper or even ridiculous.In my opinion, having idols is not a bad thing.However, we should make it clear who are the real “heroes”.As far as I am concerned, the real heroes are those who are making the most contributions to our society, such as teachers, doctors and scientists.As students, we should learn from them.Only in this way can we become useful persons in the future.15、交朋友看重的品质
Everyone needs friends.A friend can give us help and share our difficulties and happiness.But how can we make friends?
First, to make friends, you must be friendly to others.Smile at others and you are sure to get a smile in return.You should try to make a stranger feel at home wherever he happens to be.Think more of others than of yourself and never judge a person by his appearance and clothes.Second, friends should negotiate instead of quarrel.When you don't agree someone, please discuss with him.Finally, never believe in those who leave you when you are in trouble.And never leave your friend when he is in trouble.Remember, a friend in need is a friend indeed.Friends should be faithful to each other.So long as you can put your friend's interests in front of yours, you will have a lot of good friends.《登天的感觉》这本书,记载了岳晓东博士在哈佛大学心理咨询中心实习期间经手的十个咨询个案。岳博士用深入浅出的表达方式说了心理咨询的基本理论和方法,并把这些理论和方法巧妙地贯穿在各个案例中,生动讲述了他所做的这十个案例。
书中的这十个案例都给我留下了深刻的印象。例如第一个案例“我是全哈佛最自卑的人”,来访者是一位大一新生,她不能很好地适应哈佛大学的生活、学习、人际交往,觉得自己是全哈佛最自卑的人。这位来访者表现出了典型的“新生适应不良综合症”。岳博士针对她的状况,采用了“现实疗法”,帮忙她从自卑的漩涡中走了出来,重新拥抱自信的阳光。
从这个案例中,我学习到了岳博士提出的自信与自卑的关联。即人是活在相互比较的感觉中的。这种比较能够给人带来自信,也能够给人带来自卑。当一个人在与人比较中尽获自信时,他要学会与自己比较来获得自谦;而当他在与人比较中尽获自卑时,他要学会与自己比较来获得自信。自信与自卑是人自我感觉的天平,其操作的原则是平衡产生美。
从这本书中,我领悟到了心理咨询的三个方面知识。
第一个是什么叫做心理咨询。心理咨询是一项使人开心和不断成长的工作。使人开心是心理咨询的前奏曲,而使人成长才是心理咨询的主旋律。心理咨询力图使个人将不愉快的经历当作自我成长的良机。它竭力使人们用心地看待个人所受的挫折与磨难,从危机中看到生机,从困难中看到期望。心理咨询也在于帮忙人学会辨证地看待生活当中的忧愁烦恼。但这一切不是靠指教劝导得来的,而是要靠启发领悟才能获得的。用马斯洛的话来讲,心理咨询就是要使人获得“顶峰的体验”,这不就是“登天的感觉”吗?
第二个是心理咨询追求的目标是什么。心理咨询要使人从挫折中认真反省,总结经验教训,增强生活的智慧,以便能够更好地应付日后生活中可能出现的各种不愉快经历,也就是要使人更好地认识自我,开发自我,激励自我。
第三个是心理咨询之高明所在是什么。心理咨询之妙,就在于它帮忙了一个人,却让那个人感到是自己帮忙了自己,即助人自助。
我很喜爱这本书的基本构架。岳晓东博士在每个案例的后面,都加入了一段个案分析。对个案的性质、特点、咨询方针及操作方法等问题都进行了详尽的讨论。在个案中,岳博士也写了一些自己对留学美国八年的感悟和体会,并就一些资料、词汇及心理学专门术语做了相关的注释。在个案分析的后面,岳博士还加了一条心理学或心理咨询方面的小知识。
第四篇:创新实验设计方案
创新实验设计方案
单位:孔滩镇初级中学姓名:向梅
一、实验名称:品红分子在水中的扩散
二、实验药品与器材:碱性品红、蒸馏水、100ml的烧杯、药匙
三、实验步骤:
1、在烧杯中倒入80ml左右的蒸馏水。
2、用药匙取出少量(1克左右)碱性品红轻轻倒于水面。
3、静置一段时间,观察现象。
四、实验现象:
1、水中出现缕缕“丝线”并不断延伸、即品红分子逐渐往水中扩
散留下的“足迹”(此时、品红分子还未扩散均匀)。
2、最终红色的品红将均匀充满整杯水(此时、品红分子已经扩散
均匀)。
五、实验结论:
1、物质(多数)的确由微小的分子构成2、分子是不停的做扩散运动的六、设计方案:
该实验源自七年级上册教材第51页。书中介绍细胞中存在哪些物质时用蔗糖举例:将蔗糖加入水中,过一会儿蔗糖“消失”,水变甜。原因是多数物质均由分子构成,蔗糖的“消失”是构成蔗糖的分子扩散到水分子的空隙中,教科书上在文字旁将该扩散过程及结果用图的方式表现。
我用“品红分子在水中的扩散”现象代替教材的讲解及图画过程,这一改进与创新有以下优点:
1、将抽象、微观的过程变得具体、“可视”
2、将教材文字讲解的呆板、单调变得生动、“活泼”
3、将图画的虚假静态过程变为实物的真实动态过程
4、为学生学习九年级化学“分子和原子”这一内容做好铺垫
5、使学生树立“世界既是宏观的,也是微观的”这一辩证唯物
主义观点。
第五篇:科学小实验设计方案
科学小实验设计方案
实验一 实验名称:喷水比赛 器材物品:1个空可乐罐、1枚铁钉、胶带、铁锤 实验过程:
1、用铁钉在可乐罐的中部和靠近底部的地方各钻一个大小一样的小孔。
2、贴上胶带,把小孔堵上,然后把可乐罐罐满水。
3、同时扯掉胶纸,你会发现,下面的孔喷出的水比中间孔喷出的水远些。
实验原理:
水的压力与深度有关,而与水量的多少、水域的形状无多大关系。无论是辽阔的大海,还是普通的游泳池、浴缸,在1米深的水下,压力差不多都是一样的。水越深,压力越大。
实验观赏性及科技含量说明:
扯掉胶纸,下面的孔喷出的水比中间孔喷出的水远些。通过实验,学生知道了有关水的压力的知识。
实验二
实验名称:水下火山
器材物品:1个小玻璃瓶、1个广口瓶、1根长线、热水、少许红墨水
实验过程:
1、在小玻璃瓶里灌满热水,滴进些红墨水将它染红。
2、用线系着小玻璃瓶,把它沉入装有冷水的广口瓶底部。
3、于是,一朵“红云”就会从瓶底升起,伸展到水面上,好像火山喷发一样。
实验原理:
水受热时体积膨胀,变得比冷水轻。于是,红色的热水上升,冷水下沉,直到掺和均匀为止。
实验观赏性及科技含量说明:
一朵“红云”从瓶底升起,伸展到水面上,好像火山喷发一样。通过实验,学生认识到了水受热时体积会膨胀的道理。
实验三
实验名称:瓶吞鸡蛋
器材物品:1个口径适中的玻璃瓶、几个去壳的熟鸡蛋、火柴、纸片
实验过程:
1、把纸片点着后放入瓶中。
2、把剥好的鸡蛋放在瓶口上,看,鸡蛋“忽”的一下进入瓶口了。
实验原理:
玻璃瓶口比鸡蛋小,把纸片点着后放入瓶中,由于瓶子受热,空气往外排出,这时把鸡蛋放在瓶口上,过一会儿,由于瓶里空气收缩压力减少,这时在瓶外的鸡蛋由于受大气压力的作用便被推进瓶里。
实验观赏性及科技含量说明:
鸡蛋“忽”的一下进入瓶口了。通过实验,学生能够感受到大气压力的作用。
实验四
实验名称:小航船 器材物品:几个樟脑丸、1个乒乓球、1把剪刀、1盆水 实验过程:
1、把乒乓球剪成3份,修剪成小船模样,在船尾剪去一小块,再剪出一条缝。
2、敲碎一粒樟脑丸,在每个小船上放一小块樟脑,让它接触到水而不会掉下去。
3、把小船轻轻放入盛有水的盆中,让樟脑浸在水里。这时,你的船就会自动航行起来了,直到樟脑溶尽,小船才会停下来。
实验原理:
当樟脑溶入水中后,这部分的表面张力就减少了,于是,小船表面张力较大的一端拉过去,樟脑不断溶入水中,小船也就不断取得“动力”,直到樟脑溶尽,小船才静止不动。
实验观赏性及科技含量说明:
小船轻轻放入盛有水的盆中,这时,船就会自动航行起来。通过实验,学生认识到了水的表面张力。
