摘要思维进阶是科学课堂教学的终极目标,它是促进课程标准、课堂教学与科学本质三者一致性的有效方法。科学思维也是科学素养的一个重要组成部分。课堂以提升学生思维能力进阶为入手,将活动设计、问题提出、课堂研讨三个方面作为思维进阶的“路径”。为了在教学中提升学生对科学本质的理解,让学生体会和理解科学本质的内容,《点亮小灯泡》一课设计了这三大环节,帮助学生形成对科学的真正学习。整个课堂教学中都是学生在学习活动的过程中感知发现和质疑,最终理解科学的本质教学,达到思维进阶。

AbstractAdvanced thinking is the ultimate goal of science classroom teaching. It is an effective method to promote the consistency of curriculum standards, classroom teaching and the essence of science. Scientific thinking is also an important part of scientific literacy. The classroom starts with improving students’ thinking ability, and takes three aspects: activity design, problem raising and classroom discussion as the "path" of thinking advancement. In order to improve students’ understanding of the essence of science in teaching and let students experience and understand the content of the essence of science, the lesson "lighting a small light bulb" has designed these three links to help students forma real learning ofscience.Inthewhole classroom teaching, students perceive,discoverandquestionintheprocess of learning activities, and finally understand the essence of science teaching to achieve advanced thinking.

科学教育的首要任务之一是提高学生的科学素养。课堂教学中如何促进学生科学思维的教学,是值得我们老师深思的地方。在科学教学中,我们不能将学科本质的内容直接通过枯燥的方式讲给学生听,不能用满堂灌的方式,而是要通过设计指向核心素养和科学本质的活动,让学生亲身经历去体验、质疑和发现,发现自己所经历的探究学习过程与科学家一样的思考,与科学家一样的参与研究过程存在的相似性,从而达成对科学本质的认识,形成思维的进阶过程,这样才能把科学本质的理解真正到位。
我们在进行着教学理念的头脑风暴和教学行为的更新,积累了很多值得借鉴和学习的财富,同时还存在着不少问题。科学课堂上还存在对科学本质学习落实不力,具体表现有以下几点:(1)教学活动中,追求热闹繁华,表面看起来学生没有被禁锢,到处可见学生的课堂主体性,却不见教师的有效引领作用。……
