科学猜想是科学探究中的一项重要步骤,是利用已有经验,在实际观察或理论推理基础上对事物的变化趋势进行预测。《科学课程标准》明确指出,学生应能大胆猜想,有根据地进行假设,根据已有知识与条件进行实验设计来验证假设;保持对科学以及与科学有关事件的好奇心,具有一定的想象力,敢于创新。新课改改变的是理念、内容和方式,强调的是猜想、探究和发现。在《科学》(教科版3~6年级)教学实践中,我有意识地引导学生进行科学猜想,有效引领
Scientific conjecture is an important step in scientific inquiry, which is to make use of the existing experience to predict the changing trend of things on the basis of actual observation or theoretical reasoning. The Standard for Science Curricula clearly states that students should be able to make bold assumptions, base their assumptions, test designs based on existing knowledge and conditions to verify their assumptions, maintain their curiosity about science and science-related events, have certain imagination, Innovation. The new curriculum changes the concept, content and methods, emphasizing conjecture, exploration and discovery. In the teaching of Science (Grade 3 ~ 6), I consciously guide students to make scientific conjectures and effectively lead
