化学教学离不开实验,而实验主要依靠观察,观察是人类认知外界事物的基本方法。培养学生在化学实验中的观察能力需要激发兴趣,明确观察目标,制定合理的计划,观察与思考相结合,让学生主动、有目的的通过观察获取知识。一、引言化学是研究物质的结构、性质及变化规律的自然科学,实验是其主要研究手段。通过实验观察同一物质在不同条件下的变化或同一条件下不同物质的相互作用,有助于学生更直观的理解化学知识,增强学生的动手能力。实验结果通常
Chemistry teaching is inseparable from the experiment, and the experiment depends mainly on observation, observation is the basic method of human cognition of the outside world. To develop students’ abilities to observe in chemistry experiments needs to stimulate interest, clearly observe the goals, formulate reasonable plans, combine observation and thinking, and let students acquire knowledge through observation actively and purposefully. I. INTRODUCTION Chemistry is a natural science that studies the structure, nature and variation of matter. Experiments are its main research methods. By experimentally observing the changes of the same substance under different conditions or the interaction of different substances under the same conditions, it is possible to help students understand the chemical knowledge more intuitively and enhance students’ practical ability. The experimental results are usually
