我校幼师生大都来自农村,实验教学只停留在初级阶段,没有深入揭示其科学规律。学生按照书本操作,做完实验,仅对实验现象感兴趣,知其然而不知其所以然。如学生多对化学反应中的颜色变化好奇,而实验结果与实验理论不符时,不分析其原因。实验过程中缺少教师对学生的指导,存在学生动手面窄,抄别人的实验结果,组织不严,实验结果误差大,造成实验操作不规范,缺乏科学性。这种现象主要反映在学生实验报告中。针对这些问题,我们学校在实验教学中提倡“以学生为主体,教师做指导”的教学理念。
Most of our teachers and students come from rural areas, experimental teaching only stay in the primary stage, there is no in-depth disclosure of its scientific laws. Students in accordance with the book operation, finished the experiment, only interested in the phenomenon of the experiment, but I do not know why. If the students are more curious about the color change in the chemical reaction, and the experimental results do not match the experimental theory, they do not analyze the reason. Lack of teachers in the process of teaching students, there are students face narrow, copy the results of other people’s experiments, organizational lax, the experimental results of the error, resulting in experimental operation is not standardized, the lack of scientific. This phenomenon is mainly reflected in the student experiment report. In response to these problems, our school advocates the teaching concept of “taking students as the main body and teachers as the guide” in the experimental teaching.
