科学语言的合理表达是科学教学活动的重要一环,是教师与学生在课堂上传递科学信息的工具。初中科学课程十分强调学生科学语言的规范表达能力。但在日常教学行为中发现:无论是学生口头表达,还是书面表达,学生的科学语言是不规范的,这已成为制约初中学生科学素养提高的一个障碍。如何突破这一“瓶颈”?科学语言表达能力的培养已是初中科学教学的当务之急。本文试图从教师示范、情景创设、方案评析、教材依托、习题精选等五个方面加以阐述。
The rational expression of scientific language is an important part of science teaching activities, a tool for teachers and students to pass scientific information in the classroom. The junior high school science curriculum emphasizes the normative expression ability of students’ scientific language. However, in the daily teaching behaviors, it is found that the students ’scientific language is non-standard whether they are verbalized by students or expressed in writing, which has become an obstacle to the improvement of junior high school students’ scientific literacy. How to break through this “bottleneck”? The cultivation of the ability of scientific language expression has become the top priority of science teaching in junior middle schools. This article attempts to elaborate from the following five aspects: teacher demonstration, scenario creation, program evaluation, textbook support, exercises selection and so on.
