在初中科学实验教学中普遍存在着学生分组实验开出率不高、实验与教学内容同步性不够、课外实验探究活动关注不多、实验改进和创新开展较少等现象。怎样才能在较短的时间内让科学教师的实验意识得到加强?学生实验操作能力得到提高?实验教学向课外延伸并取得成效,是摆在科学教师面前的课题。为提高科学实验教学的实效性,我们从实验过程管理、实验改进创新和开展实验探究方面进行探索和研究。一、强化实验过程管理,开足开好科学实验由于实验条件的客观限制,教师对实验教学的认知偏差以及评价手段的滞后,当前初中科学实验教学
In the junior middle school science experiment teaching, there is a lot of problems such as the low rate of grouping students in experiment, the lack of synchronicity between experiment and teaching content, the lack of attention in extracurricular experiment exploration activities, the less experiment improvement and innovation. How can we enhance the experimental teachers ’sense of science in a relatively short period of time? How to improve the students’ ability of experimental operation? To extend the experimental teaching to extracurricular and achieve the desired result is a topic for science teachers. In order to improve the effectiveness of science experiment teaching, we explore and study from the aspects of experimental process management, experiment improvement and innovation and experiment exploration. First, to strengthen the management of the experimental process, open enough to open a good scientific experiment Due to the objective constraints of experimental conditions, teachers’ cognitive bias in experimental teaching and evaluation tools lag, the current junior high school science experiment teaching
