“一条船上有75头牛,32只羊,问船长几岁?”在我国小学和初中的测试中,竟有超过90％的学生得出船长43岁的答案。简单的问题,如此的回答,难道不令人深省吗?这不能不说与我们长期不进行“问题”意识培养和训练不无关系。我认为“问题”意识应贯穿教育教学的始终,各级各类学校都应予以重视。 事实上,真正的创新,真正的科学发现,往往从提出一个与众不同的、有科学价值的问题发问。问一个“为什么”,将有效地促进对隐藏在现象背后的规律或缘由进行探索;而“怎么样”的问题常常引起过程机理的思考。因此,在教学时,既要鼓励学生提出问题,又要引导学生积极思考如何解决问题,不能对学生提出的问题置之不理,也不能说这个问题没水平,那个问题没深度,更不能视提出的问题荒谬。 “There are 75 cattle and 32 sheep in a boat and asks the captain how old?” In our elementary and junior high school tests, as many as 90% of the students came to the captain's 43-year-old answer. Is it not inconceivable that simple questions and such answers should be answered? This can not but be said to have nothing to do with our long-term failure to cultivate and train “problem” awareness. In my opinion, the awareness of the “problem” should always permeate education and teaching, and all kinds of schools at all levels should pay attention to it. In fact, true innovation, real scientific discoveries, often ask questions that raise a distinctive and scientifically valuable question. To ask a “why” will effectively facilitate the exploration of the laws or causes behind the phenomena; and the “what-if” questions often give rise to the consideration of process mechanics. Therefore, in teaching, we should not only encourage students to ask questions, but also guide students to think positively about how to solve the problems. They should not ignore the problems raised by students, nor should they say that the problem is not level. absurd.
