中文简介: | 整个欧洲在生物教育方面存在许多严重的问题,正如组织了六年国际生物教育讲习班的经验所表明的那样。这些问题并不是普遍存在的,但大多数欧洲国家的中学生物学教师(可能是大多数教师)都经历过这些问题。一份非详尽的清单包括:超负荷而过时的课程、过时的教科书、没有足够的时间来涵盖内容、没有足够的现实;实践工作,生物学范围的局限,生物学作为一种软的认识学科、教学方法不当、缺乏对教师创造性和独立性的鼓励、缺乏教师的积极性、缺乏正规的持续教师培训、学生对学科缺乏热情;这是前面许多问题的结果。作为教育工作坊的组织者,我们把中学生物教师视为科学家,因为我们认为科学家是对科学及其方法有专业知识,并能与科学交流的人。因此,作为生物学家,我们的共同目标是改进上述所有问题。但是,有一些优先事项应该集中注意,而且其他改进将几乎自动地从这些优先事项中进行。例如,如果生物学教师被更多地视为真正的专业人员,那么就必须为他们提供专业发展的手段,这意味着在他们的学科、方法和教学法方面的更新或定期培训机会。研究所和大学的研究人员和其他科学家是这种改进的关键部分。目前许多人从事自愿工作,很少或没有经济报酬。但是,这项服务如果要维持和满足需求,就必须得到资金和扩大。最终,这一切都是为了证明教师是重要的,是被关心的。这本身就可以极大地帮助教师提高道德和积极性,但也必须鼓励独立和创造性,并在拥挤的教学项目中提供必要的时间。这药剂,t,需要针对这些变化趋势,使他们更加困难,但更必要的:越来越多的知识,更多的集中在获得好的考试成绩,一系列令人眼花缭乱的non-curricular信息源(如网站、门户网站等)和对科学的热情下降一般的年轻人。最后的观察使我们将生物学教育放在科学和社会其他发展的背景下看待。从1998年起,欧洲每年的科学产出超过美国(科学文献的发表数量)。但我们不能自满(事实上,美国也不能),因为研究表明,可能在所有欧洲国家,15岁的学生对学校的科学不感兴趣,也不认为科学和技术领域的职业是有吸引力的。就生物学而言,我们至少应该关注以下三个原因:1)对科学的负面看法导致学生选择错误的生物学;原因(“;soft”选项);2)其他重要的生物学学科的代表性不足;3)全球的科学生产速度正在提高,可以说是受到生物学的推动,而且最近出现了新的研究领域:至少我们需要确保年轻人意识到正在发生的事情,并能欣赏到其中的重要意义。事实上,在欧洲,生命科学的生产力(每年出版的出版物)比任何其他科学领域都要高。信息的explosion”发生在生物学;由“;-omics”生物学技术与新分支;对研究和教育都有影响,并且更加强调在学校如何教授生物的重要性;对于那些想要在大学里学习it的人和那些想要成为新事物的消费者;生物学在未来。这种划分并不简单,因为如今生物学已经变得如此复杂,以至于一些教育体系(例如英国)已经开设了两门课程:一门是为了进一步学习的科学,另一门是为了公民身份的科学。就大学学习和以后的研究而言,在生物学中,跨学科发挥着越来越重要的作用。在现代生物学中,学科边界正在迅速跨越,新的学科正在形成,新的综合见解和知识正在创造。这需要在许多科学领域具有开放和知识的头脑。在学校里,生物课已经可以介绍一些这方面的基本概念。生物学为那些足够好奇想要进入高等教育的人提供了广阔的视野。系统生物学就是这样一个领域。它基本上集成了来自较小研究领域的信息,以理解系统是如何工作的;从生物合成途径到环境现象;工作。此外,它可以用来介绍生物学的一系列具有重大社会意义的现代重要进展,从分子医学到分子进化。但它也催生了一项诱人的新技术:合成生物学。系统生物学也很有趣,因为它出色地证明了,虽然计算机可以帮助我们生成大量的数据,但最终是聪明的人类头脑将在理解其意义和力量方面取得突破。这些聪明的头脑需要从学校开始培养。尽管分子进化的名字听起来很吓人,但大多数人都很容易理解它,也很容易教会它。基因和基因产物(蛋白质)以一定的速率发生突变,这一原理使它们可以作为分子时钟,以更快或更慢的速度滴答作响;这有点像几百或几千年前,欧洲语言中单词从一个共同词根突变的方式。这样我们就可以画出进化树,这些树比比较解剖学、生理学或胚胎学更能预测物种之间的真实关系。然而,纵观欧洲各国的生物学课程,我们发现不超过20%的课程是指定教授分子进化的。把新生物引入学校教学的解决办法并不容易。它们必须结合几个特性,或者探索某些思想。有些概念很容易插入到课程中(例如分子进化),它们应该出现在所有课程中。为了节省空间,它们可以用来介绍其他概念,如分子医学(通过基因组学和蛋白质组学,这在分子进化研究中是重要的),甚至一些基本的东西,如为什么动物模型在人类疾病研究中有用。其他主题可能会在课程开放时引入。新研究:以色列魏茨曼研究所正在进行的一项实验。同样重要的是,老师们定期碰面,讨论新的研究(如发表在《自然》或《科学》杂志上的文章),以及如何在课上提及;在这方面,经常与研究人员进行交流是很有帮助的。最后,这又引出了教师培训的问题。课程和课本只是实物,永远不会过时,但教师是知识、思维和热情的鲜活传播者。必须普遍认识到,在各研究所和大学的科学家的帮助下,将教师聚集在一起进行定期在职培训的重要性,这是改进的关键部分。 |
课程简介: | Across Europe there is a number of serious problems in biology education, as EMBO’s experience of organising international biology education workshops for 6 years shows. These problems are not universal, but they are experienced by a large fraction of teachers (possibly most teachers) of biology at secondary level in most European countries. A non-exhaustive list includes: overloaded and outdated curricula, outdated text books, insufficient time to cover contents, insufficient “real” practical work, limitations of the scope of biology, the perception of biology as a “soft” subject, inappropriate pedagogy, lack of encouragement of teacher creativeness and independence, lack of teacher enthusiasm, lack of formal continuous teacher training, and, finally, a lack of student enthusiasm for the subject – which results from many of the preceding problems. As organisers of education workshops, we treat secondary school biology teachers as scientists, because we consider a scientist to be someone who is professionally knowledgeable about science and its methods, and can communicate science. Our common goal as biologists, therefore, is to improve on all of the problems mentioned above. But there are certain priorities that should be concentrated on, and from which other improvements will follow almost automatically. For instance, if biology teachers are treated more as true professionals, then they must be provided with the means for professional development, and that means updates, or regular training opportunities, in their subject matter, its methods and pedagogy. Researchers and other scientists in institutes and universities are vital part of this improvement. Currently many are engaged in a voluntary capacity, with little or no financial recompense. This service, however, has to be financed and expanded, if it is to be sustained and meet demands. Ultimately it is all about demonstrating that teachers are important, and are cared for. That in itself can help enormously to improve teacher moral and enthusiasm, but independence and creativity have to be encouraged too, and the necessary time made available in crowded teaching programmes. As if that weren’t enough, these changes need to be made against trends that make them even harder, but even more necessary: an increasing amount of knowledge to be covered, more concentration on attaining good exam results, a bewildering array of non-curricular information sources (e.g. websites, Internet portals, etc.) and falling enthusiasm for science in general among young people. The last observation leads us to view biology education in the context of other developments in science and society. From 1998 onwards Europe has a greater scientific output per year than the USA (number of publications in scientific literature). But we can hardly afford to be complacent (neither can the USA, in fact), because research shows that probably in all European countries, students of age 15 are not keen on school science, and do not see a career in science and technology as attractive. In terms of biology, we should be concerned for at least three reasons: 1) a negative perception of science leads students to choose biology for the “wrong” reason (“soft” option); 2) other scientific disciplines important to biology are underrepresented; 3) the rate of production of science globally is increasing, arguably driven by biology and recently emerged new research areas: at the very least we need to ensure that young people are aware of what is going on and can appreciate something of its significance. Indeed, in Europe, the productivity of the life sciences (in publications per year) is greater than any other scientific field. The “information explosion” happening in biology – driven by “-omics” technologies and new branches of biology – has consequences for research and education, and puts more emphasis on the importance of how biology is taught in school – both for those wishing to study it at university, and those who will be consumers of the “new” biology in future. The division is not trivial, because biology has become so complicated these days that some educational systems (e.g. the UK) have developed two kinds of course: science for further study, and science for citizenship. As far as university study, and later research, in biology are concerned, transdisciplinarity plays an increasingly important role. In modern biology, subject boundaries are rapidly being crossed, new disciplines made, new integrative insights and knowledge created. This requires minds that are open and knowledgeable in a number of scientific areas. Already at school level, biology classes can introduce some of the basic concepts of this “new” biology as a horizon-expander for those who are curious enough to want to go into tertiary study. Systems biology is one such area. It basically integrates information from smaller areas of research to understand how systems – from biosynthetic pathways up to environmental phenomena – work. Furthermore, it can be used to introduce a range of important modern advances in biology that have great societal relevance, from molecular medicine to molecular evolution. But it also enables a tantalising new technology: “Synthetic biology” Systems biology is also interesting from the point of view that it excellently demonstrates that whereas computers can help us generate massive amounts of data, it is ultimately bright human minds that will make the breakthroughs in understanding its significance and power. These bright minds need to be cultured starting at school. Molecular evolution, despite its formidable-sounding name, is something that can be easily understood by most people, and can easily be taught. Essentially it is the principle that genes and gene products (proteins) mutate at rates that allow them to be used as molecular clock with faster or slower rates of ticking – a bit like the way words mutate in European languages from a common stem, hundreds or thousands of years ago. This then allows us to draw evolutionary trees that are better at predicting the true relationship between species than comparative anatomy, physiology or embryology. However on inspecting national biology curricula across Europe, we find that in no more than 20 % of curricula is molecular evolution specified to be taught. Solutions to introducing new biology to school teaching are not easy. They must incorporate several features, or explore certain ideas. Some concepts are so easily inserted into curricula (e.g. molecular evolution), that they should appear across the board. To save space, they can be used to introduce other concepts such as molecular medicine (via genomics and proteomics which are important in molecular evolutionary studies), and even things as basic as why animal models are useful in research on human diseases. Other topics might be introduced by making a part of the curricula “open” for new research: an experiment being tried at the Weizmann Institute in Israel. Of equal importance is that teachers meet each other regularly to discuss new research (e.g. reported in Nature or Science), and how they can mention it in their lessons; regular interactions with researchers can be very helpful in this respect. And finally this brings us to the matter of teacher training again. Curricula and text books are mere objects, and will always be out of date, but teachers are the living breathing transmitters of knowledge, thinking and enthusiasm. The importance of bringing teachers together for regular in-service training with the help of scientists at institutes and universities must be generally recognised as a critical part of the recipe for improvement. |
