化学实验在近数十年中,随着讲授内容的更新,它也起着相应的变化。由于实验的指导思想往往偏重于验证课文中的有关知识,因此对整个实验的安排,包括要求、步骤和报告形式等各个方面都有一套常规。实践证明,它的效果并不理想。加强实验教学是提高化学教学质量的重要一环。国内许多从事化学教学的同志正在这方面进行探索,提出各种具有积极意义的设想,并加以实践。当前,国外的化学实验教学也不断地在起变化,它主要也是围绕如何培养能力这一重要问题。美国《实 In recent decades, chemistry experiments have also evolved as the contents of the lectures have been updated. Because the guiding ideology of experiments is often focused on validating the relevant knowledge in the text, there is a set of routines in all aspects of the overall experiment arrangement, including requirements, steps, and reporting forms. Practice has proved that its effect is not ideal. Strengthening experimental teaching is an important part of improving the quality of chemistry teaching. Many comrades engaged in chemistry teaching in China are exploring in this area and put forward various positive ideas and practices. At present, the teaching of chemistry experiments abroad is constantly changing. It is mainly about how to cultivate the important issue. United States
