Singapore has embraced the life sciences as an important discipline to be emphasized in schools and universities. This is part of the nation's strategic move towards a knowledge-based economy, with the life sciences poised as a new engine for economic growth. In the life sciences, the area of developmental biology is of prime interest, since it is not just intriguing for students to know how a single cell can give rise to a complex, coordinated, functional life that is multicellular and multifaceted, but more importantly, there is much in developmental biology that can have biomedical implications. At different levels in the Singapore educational system, students are exposed to various aspects of developmental biology. The author has given many guest lectures to secondary (ages 12-16) and high school (ages 17-18) students to enthuse them about topics such as embryo cloning and stem cell biology. At the university level, some selected topics in developmental biology are part of a broader course which caters for students not majoring in the life sciences, so that they will learn to comprehend how development takes place and the significance of the knowledge and impacts of the technologies derived in the field. For students majoring in the life sciences, the subject is taught progressively in years two and three, so that students will gain specialist knowledge in developmental biology. As they learn, students are exposed to concepts, principles and mechanisms that underlie development. Different model organisms are studied to demonstrate the rapid advances in this field and to show the interconnectivity of developmental themes among living things. The course inevitably touches on life and death matters, and the social and ethical implications of recent technologies which enable scientists to manipulate life are discussed accordingly, either in class, in a discussion forum, or through essay writing.
新加坡已将生命科学视为学校和大学中需要重点强调的重要学科。这是该国迈向知识型经济的战略举措的一部分,生命科学有望成为经济增长的新引擎。在生命科学领域,发育生物学备受关注,因为了解单个细胞如何发育成一个复杂、协调、功能完备的多细胞、多面的生命体,不仅对学生来说饶有趣味,更重要的是,发育生物学在生物医学方面具有诸多重要意义。在新加坡教育体系的不同阶段,学生们接触到发育生物学的各个方面。作者为中学生(12至16岁)和高中生(17至18岁)举办了多次客座讲座,激发他们对胚胎克隆和干细胞生物学等主题的兴趣。在大学层面,发育生物学的一些精选主题被纳入一门更广泛的课程,面向非生命科学专业的学生,使他们学会理解发育是如何发生的,以及该领域所衍生的知识和技术的意义及影响。对于生命科学专业的学生,该课程在大二和大三逐步展开教学,以便学生能够获得发育生物学的专业知识。在学习过程中,学生们接触到发育背后的概念、原理和机制。通过研究不同的模式生物,展示该领域的快速进展,并呈现生物之间发育主题的相互联系。该课程不可避免地涉及生死问题,以及科学家操控生命的最新技术所带来的社会和伦理影响,会在课堂上、讨论论坛中或通过写作进行相应讨论。
