约翰·斯特林格是与英国最大的中小学出版公司——哈考特教育公司长期合作的一位资深教材编写专家,英国最受欢迎的科学教材New Star Science的一位作者。他曾做过小学科学教师、校长、培训师、培训顾问、督学,同时还在大学任教。同时他还为英国的两家教育电视台BBC和第四频道合作,参与制作的节目达200多个,并为此多次获得皇家电视协会奖(RTS),还一度获得英国电影电视学院(BAFTA)奖提名。

四月的北京,和风拂面,春意盎然。2006468日全国外语特色学校研讨会在外研社国际会议中心召开。会议期间,笔者采访了应邀参会的英国知名科学教材专家约翰·斯特林格。斯特林格先生回顾了英国科学教育发展的历程、阐述了科学教育的原则、介绍了英国最受欢迎的科学教材《发现科学》(New Star Science的编写理念及对中国科学出版的借鉴意义。

您能否介绍一下英国科学教育的发展历程?你对中国的科学教育有何建议?

在英国,科学教育在中学阶段历来都十分重要。但在小学阶段,情况则有所不同。实际上,以前在小学根本没有开设科学课。学生学习的是自然科学魔法课。这些课程讲述的主要是动植物、季节之类的内容。我在上学时起就立志做老师,因为我发现向孩子传授科学知识令人兴奋。 上世纪60年代,小学科学教育的情形开始好转。1965年,汽车制造商勒菲勋爵鼎力资助一个促进小学科学教育发展的项目。教师们个个兴奋不已。但遗憾的是,小学科学教育并没有太大的改观。

直到1989年,新的国家课程标准出台,规定了三门主课:英语、数学和科学。这就意味着从当年开始,英国所有小学各个年级都要进行科学考试,并且考试成绩对于他们日后升学或者毕业意义重大。科学课突然变得重要起来,其重要性远远超过了地理、历史之类的课程。科学教师也突然变得有用起来。他们行动起来,组建了强大的社团来推广科学教育。

我们在科学教育上曾经走过不少弯路,希望中国在这方面可以避免。第一、我们操之过急,在一开始就试图向学生传授太多的知识。科学知识浩如烟海,开始时我们应该传授那些孩子们感兴趣的内容。因此,教师们在选择材料进行教学时,一定要慎之又慎。第二、我们让中学教师告诉我们在小学阶段应该怎么教,结果带来了一系列问题。小学生很难掌握艰深的科学概念。实际上,小学生在开始时要接触到实物,处理切实的问题,然后循序渐进,接触更加晦涩难懂的内容。换言之,学习要由易到难,真实的学习源自于接触生活中的实物。

您认为科学教育中科学知识和科学方法哪点更重要?换言之,哪一点学生更应该掌握?

科学知识和科学方法都非常重要。科学知识是基础。如果没有基础,学生就会成为无源之水,很难自己做出什么独到的发现。反过来,科学方法涉及到关于如何发现的技巧等,对于学生做实验和发展他们的批判性思维都很有帮助。因此教师应该鼓励学生学习科学知识的同时,还应该学习科学方法。

在现代世界,生活变化非常迅速。科学知识也在不断更新。例如,我们过去认为光的速度最快。但现在人们发现离子运动的速度远远高于光速。这就意味着我们今天的知识在未来也许会过时,从这个角度来说科学方法似乎更为重要一些,当然我们还是需要掌握基本的知识的。另外,科学并非常识。科学往往让我们吃惊、兴奋,科学是非凡的、具有魔力的。教师们在上课举例时应该谨慎。例如,为什么小树会长大?促使树长大的物质来自哪里?学生可能会提出类似的问题。众所周知,树能长大主要是因为光合作用。也就是说,固体的树是由水和二氧化碳变来的。 学生们在走进校门的时候,对于世界已经有了一个朦胧的认识。一次,我问学生天为什么会变黑?下面是他们的回答:

月亮/乌云遮住了太阳。

太阳熄灭了。

太阳离我们太远了。

……

科学教师应该向学生展示一些活动或者让他们有些体验,挑战他们已有的认识,鼓励他们理解约定俗成的科学观点,然后孩子们就可以运用这些基本知识去挑战事实。我们并不鼓励学生想当然的去接受某些事实。给学生们创造一些机会,亲自去检验自己的观点对于他们的发展非常有利。

在你看来,科学教育的目的是什么?

在现代世界,缺乏对科学的理解将会寸步难行。科学对于我们来说非常重要,它可以帮助我们更好地理解世界。科学教育的目的并非是将每个学生培养成科学家,而是让他们学会应对日常生活中的难题。毕竟,我们身边处处是科学。一次我去一家幼儿园访问,那里的老师说道:我们这儿的一切与科学都沾不上边。孩子们年龄太小了。但是我看到,孩子们都在制作模型、垒起玩具砖等,其实这些都属于科学实验的范畴。打下扎实的科学基础、掌握解决问题的合理方法,能够使孩子们更好地理解身边世界,使他们能对于这个科技社会做出应有的贡献。以禽流感为例,如果我们对这方面的科学有所涉猎,我们就会明白人类死于禽流感的几率远远低于死于心脏病和交通事故。

你从事科学教育已经四十多年,从事写作也有二十多个年头了。你的教学经验对于你的写作有何帮助?

我总是在向孩子们学习。实际上,我从孩子们身上学到的要多于我教给他们的。科学涉及到方方面面的问题。学生们问到的一些问题非常具有建设性。我从学生那里搜集到不少好的想法,然后将它们写进教材。有时他们会教给我一些新词,我会在书中吸收一些不错的词汇,甚至他们的一些绘画。另外,我对学生非常了解,因此当我在选择科学材料时,我知道哪些材料比较合适,能够挑战他们的思维。

《发现科学》(New Star Science) 的教育理念是什么?

说到本系列书的教育理念,有两点可以称道的地方:首先,孩子们理解科学需要掌握的基本事实,在一开始我们就给出了解释。这些解释在全书显要位置出现。其次,我们编纂了一个配套的科学技能阶梯,它对于学习本套教材的学生发展科学技能非常有用。在学习本套教材时,首先我们需要根据学生水平将他们划成三个等级:能力较强的、能力较弱的、中间水平的。我们力争做到因材施教。其次,我们将科学过程分成三个阶段:计划、获取和展现证据、思考和分析证据。每节课的重点也许会有所侧重,但在一个完整的探究过程均包含这三部分。计划非常重要,教师要负责做好计划。计划的具体内容包括:1. 提出问题,给出想法;2. 决定适当的教学方法;3. 预测可能发生的情况;4. 选择使用的仪器。获取和展现证据简而言之就是。 其具体内容不外乎:1. 利用仪器,安全地开展具体教学任务;2. 观察、测量;3. 展示证据。思考和分析证据实际上指的是复习。 其具体内容包括:1. 作出结论、描述模式和趋势;2. 将结果与预测对比,并进一步作出推测;3. 解释证据;4. 分析证据。本系列书所有材料都是围绕着这个技能阶梯展开的,这样做可以确保学生既能掌握知识又能掌握技能。

我们了解到,《发现科学》(New Star Science)在英国是使用人数最多的科学教材。本系列前面有无一套Star Science教材?《发现科学》较之有哪些比较新颖的东西?它有哪些卖点?

是的,有一套Star Science教材。1984年开始,我开始与老牌学校用书出版商Ginn合作。在国家课程标准出台之前,我参与了Ginn Science教材的编写,接着又参与了Star Science教材的编写。随着新的教学模式的引进、教学理念的发展,教学材料和教学时间必须压缩,因此我们又编写这套《发现科学》(New Star Science)

《发现科学》很受学生欢迎,我想:

首先是它符合课程标准的要求,内容比较全面。

其次,其结构呈螺旋式上升,同样的材料会在更高难度复现,以便学生掌握更难的概念和技能。

第三,插图精美,内容有趣。为了吸引学生的兴趣,增加教材内容的多样性,我们还按照级别在书中整合了诗歌、谜语及故事等特色。

第四,词汇和学生的水平相当。我们总是试图用最简单的语言来表述内容。一些单词既有日常含义又有科学含义,比如key, table, fair。为了防止孩子们误解,我们总是从孩子的角度给出全面的解释。

第五,我们配备了丰富的教师资源。教师们工作总是非常繁忙。在《指导用书》里,我们设计了一些问题来挑战学生,并提供了参考答案供教师参考。另外里面还有背景知识等参考资料。总之,在教室用书里,我们试图做到言简意赅,使教材更易于操作。

本系列主要涉及到哪几方面的科学?你们是如何将这些科学材料整合在一起的?

本系列教材主要涉及到自然科学、材料科学和物质科学等。本系列书的结构就像你的手指:自然科学、材料科学和物质科学好比中间三个较长的指头,小指主要是关于科学的历史、应用和发展等,拇指主要指科学活动,特别是探究活动这种技能方面的科学。没有拇指,整支手便毫无用处,探究的重要性可见一斑。

你对要出版小学科学教材的中国出版社有什么建议?

首先,语言非常重要。书中的语言必须是学生比较熟悉的。其次,要决定选用一种构建知识的方法。你们必须将知识分解成易于操作的小块知识,以便学生可以按部就班地学习。第三,书中举的例子最好比较有意思,与日常生活息息相关,更重要的是可以挑战学生的思维。孩子们喜欢阅读一些比较可怕、愚蠢的例子或者是一些非比寻常的、出人意料的东西。除此之外,一些不可能的事情、滑稽可笑的事情等也不妨有所涉及,以便吸引他们的兴趣。

What is the history of science education in UK? What suggestions would you make for countries such as China to follow?

Science education is very important in secondary school in the UK. However, it was not true for primary schools at first. Actually, science wasn’t taught in primary schools for a long time. Children learned Nature or Science Magic instead. These subjects mainly tell pupils about plants and animals, seasons, and things like this. I went to study as a teacher because I found teaching young children very exciting while taking science with me.

Things changed for the better in the 1960s. In 1965, Lord Nuffield, a carmaker sponsored a project which is devoted to teaching science to young children. Teachers were quite excited about this. Unfortunately, nothing much happened.

In 1989, the new national curriculum came out with three major subjects: English, Math and Science. That is, every English child would have to take Science exams at all grades across the UK since 1989. The test results would have a tremendous influence upon their further education. Science suddenly became important, more important than history, Geography. And Science teachers suddenly became very useful. They formed a strong community in promoting science.

We have made lots of mistakes in science education, which I hope can be avoided by China. First, we tried to do far too much. That is, we tried to let students learn a lot at the very beginning. As science is enormous, we should only focus on things that interest children. Teachers should carefully choose materials. Second, we let secondary teacher tell us what we should do at the primary level. It makes all kinds of problems. Primary students have difficulty in learning difficult concepts. In fact, students have to see concrete things, handle real things at first. Gradually, they can learn more difficult things. Real learning comes from real things. That is, students have to learn from easy to difficult.

Do you think what’s more important in science education, science facts or scientific methods, or which is more important for students to acquire?

Science facts and scientific methods are equally important. Science facts are the basis. Without them, students would find it very hard to find or discover for themselves. On the other hand, scientific methods are about how to discover, and can serve as a helpful tool in doing experiments and developing critical thinking. So teachers should encourage students to study not only the science facts but also the methods.

In modern world, life changes very fast. And the knowledge of science can constantly change. For example, we used to believe that light travels the fastest. However, particles have been discovered that appear to travel even faster than light. That is, what we have known may be out of date someday. From this perspective, scientific methods seem more important though we need to know the basic facts.

Also, science is not common sense. It is always surprising, extraordinary, exciting and magical. Teachers should be careful in giving examples. For example, “why does a tree get bigger and bigger? Where are the materials from?” Students may ask such questions. As we know, trees get big mainly because of photosynthesis. The solid wood of a tree was once water and carbon dioxide.

Children come to school with their own ideas about the way the world works. Once I asked students why it is getting dark at night. The following is their responses:

The moon / Clouds come(s) in front of the sun.

The sun goes out.

The sun is a long way away from the earth.

The teacher of science should present them with activities and experiences that challenge their ideas and encourage them to develop an understanding of accepted science ideas. Then children may use the basic knowledge to challenge evidence. We don’t encourage students to accept things as it is. Giving children practical experience of testing their ideas is critical to their development.

What’s the purpose of science education in your opinion?

We can’t live in the world without understanding of science. Science is very essential to us and helps us better understand the world. The purpose of education is not to train every student to be a scientist, but to learn how to cope with problems in our daily life. After all, science is all around us. Once I went to a nursery school, the teacher there said, “We don’t do anything about science. They are too young for that.” But I saw children making models, playing toy bricks, etc. Actually, these are science experiments. A firm grounding in science and a logical approach to problems, will enhance every child's understanding of the world around them and enable them to contribute fully to a technological society. Take bird flu for example. If we have some basic knowledge of science, we would realize that it’s much more likely we shall die of heart disease or a road accident.

You have been teaching science to young children for nearly forty years and writing about it for twenty. How does your teaching experience help with your writing?

I always learn from children. Actually, I learn more than I teach. Science is about questions. Some of their questions are very productive. I collect some good ideas from pupils, then write them down in the textbook. Sometimes, they teach me some new phrases. I’ll adopt some good words and even some of their drawings in the books. Also I know my students very well, so when I choose science materials for the books, I know what material are right and able to challenge their thinking.

What’s the theory that supports your New Star Science? Or ideas?

You mean the philosophy behind it? It has two great strengths; first, we have defined the key facts that children need to understand to make sense of science. These are highlighted throughout the books. Then we’ve got a New Star Science Skills Ladder, which helps children develop their science skills as they work through the scheme. First we need to match the children to their level: more able, less able and the middle. We try to ensure students at different levels do the right things. Second, we divide the scientific process into three phases-- planning, obtaining and presenting evidence, considering evidence and evaluating-- and while the emphasis may vary, all three parts are present in a whole investigation. Planning is very important and teachers are responsible for it. This part includes: 1. asking questions and having ideas; 2. deciding an appropriate approach; 3. planning the detail of what to do; 4. predicting what might happen; 5. choosing what equipment to use. Obtaining and presenting evidence is actually the “doing” part. It includes: 1. using equipment and carrying out practical work safely; 2. making observations and taking measurements; 3. presenting evidence. Considering evidence and evaluating is the “reviewing” part. It includes drawing conclusions and describing patterns and trends; 2. comparing results to predictions and making further predictions; 3. explaining evidence; 4. evaluating. All the materials center around this ladder to ensure knowledge and skills come together.

As we all know, New Star Science is one of the most widely used science scheme in the UK. Is there a Star Science before this series? What have you done in updating the series? What’s its USP?

Yes. I’ve been working with Ginn since 1984. Before the National Curriculum came out, I worked on ‘Ginn Science’ – named after the publisher; then on “Star Science”. As new models were brought in and the ideas moved on, teaching materials and time had to be trimmed, hence New Star Science.

New Star Science is very popular among students, well, first I think it conforms to the National Curriculum. It’s very comprehensive. Second, it has got a growing structure. It goes over the same materials but with a higher concept / skills level. Third, it’s got very attractive illustrations and content. In order to attract their interest and to add variety, other features such as poems, riddles and stories are demonstrated at different grades. Fourth, the words match the children. We always try to keep the language as simple as possible. Some words have everyday and science meanings, like key, table, fair. In case they are misunderstood, we always give full explanations from the children’s perspective. Fifth, we equip the book with a rich teacher’s resource. Teachers are very busy people. For example, in Teacher’s notes, we designed “QUESTIONS” to challenge children and provide “POSSIBLE ANSWERS” for teachers’ reference. Also the “BACKGROUND INFORMATION”, etc. All in all, we provide simple notes but easy management.

What areas of science are touched upon in the series? How do you structure the science materials?

This series covers natural science, materials and the physical science. The structure of science is like the fingers of your hand. The three familiar content areas --- the natural sciences, materials and the physical sciences --- are like three long fingers. There is a little finger concerned with the history, applications and development of science, and the thumb without which the hand is useless – scientific activity – especially investigations, the skills area of science.

What advice would have for a Chinese publisher who wants to publish science course books for primary school students?

Well, first comes the importance of language. The language adopted in the book must be familiar to young children. Second, you have to decide on which skills / facts to build knowledge up. You’ve got to break skills down into manageable chunks so that children learn at the right pace. Third, facts are always good to be interesting, related to their daily life, more important, able to challenge their thinking. Children like reading some horrible, silly facts, unusual facts or things that are quite unexpected. You may write down such things as well as unlikely things, fun facts, etc. to arouse their interest.
