摘  要 “三学三萌”微课程的目标是培养学生的科学素养，科学素养目标和学生认知能力的匹配度是设计科学校本课程的理论依据，年段目标和主题选择的适切性是校本课程研发的关键所在。在设计“三学三萌”微课程时要着重锤炼科学理性思维。教师要积极营造多课程整合的实施条件，开展“做中学、做中研”的科学实践活动，激发学生开展科学微课程研究的兴趣，发展他们的探究能力，培育他们的科学探索精神，让他们受到更广泛的科学思想、方法、情感态度与价值观的熏陶。

Abstract： The goal of "three-learning and three-sprouting" micro course is to cultivate students' scientific literacy. The matching degree of scientific literacy goal and students' cognitive ability is the theoretical basis for the design of science school-based curriculum. The appropriateness of year stage goal and topic selection is the key to the development of school-based curriculum. In the design of "three-learning and three-sprouting" micro course， we should hammer scientific rational thinking. Teachers should actively create the implementation conditions of multi curriculum integration， carry out the scientific practice activities of "learning by doing and researching by doing"， stimulate students' interest in scientific micro curriculum research， develop their inquiry ability， cultivate their spirit of scientific exploration， and let them be influenced by a wider range of scientific ideas， methods， emotional attitudes and values.

低年段倡导“学中萌趣”，体验科学真好玩

低年段“吹泡泡”项目，考虑到学生对新奇的东西有天生的探究欲望，有爱玩爱动的特点，设计了8个小主题（如右下图），通过一个个问题串联起来。以泡泡为主线，学生在“玩泡泡—做泡泡器—吹更大的泡泡”的活动体验中收集资料，动手实践，体会到吹泡泡的乐趣，感受到科学实验的奥秘。

在该项目实施的过程中，学生对制作泡泡器和吹更大的泡泡非常感兴趣。有的学生认为：泡泡器的形状会影响泡泡的形状，如三角形的泡泡器吹出来的泡泡应该是三角形的，但反复试吹后发现泡泡都是圆形的。……
