对于高中阶段的化学教学而言,概念教学既是基础也是重要内容。如果高中生在具体的学习过程中,针对概念的本质及内涵,如果能够精准地把握和理解,他们的化学学习成果必然非常高效。但是,就当前的教学实践来看,很多教师在教化学概念时,仍然选择传统的讲解式教学方式。如果长期处于这种教学模式之下,高中生在学习实践中就会始终处于被动状态,这与当前以学为中心的教学目标相违背。在高中阶段化学课堂的教学实践中,对于化学概念的教学,首先应当注重情境化, For high school chemistry teaching, concept teaching is not only basic but also important. If high school students in the specific learning process, for the nature of the concept and content, if we can accurately grasp and understand their chemical learning results must be very efficient. However, judging from the current teaching practice, many teachers still choose the traditional narrative teaching method while teaching the concept of chemistry. If this long-term teaching mode, high school students will always be passive in their learning practice, which is contrary to the current teaching-centered teaching objectives. In the high school chemistry class teaching practice, for the teaching of chemistry concept, we should pay attention to the context first,
