在高中化学教学中,概念教学是基础内容,同时也是重点内容。如果高中生在化学学习的过程中,没有正确地理解化学概念的本质内涵,那么,他们的学习肯定是低效的。但是,现在很多教师在教学高中化学概念时,还存在“讲解”式的教学现象,在这样的教学模式下,高中生对化学概念的学习就很被动。在“学为中心”的高中化学课堂教学中,化学概念教学要注重情境化、探究化、对比化,这样,才能让高中生的化学概念学习更高效。 In high school chemistry teaching, concept teaching is the basic content, but also the key content. If high school students do not correctly understand the essential connotation of the chemical concept in the process of chemistry learning, then their learning must be inefficient. However, many teachers nowadays teach “high school” chemistry when they are teaching high school chemistry concepts. In such a teaching mode, high school students’ learning of chemical concepts is very passive. In the “learning as the center” of the high school chemistry classroom teaching, chemical concept teaching should focus on contextualization, exploration, comparison, so that high school students learn the concept of chemistry more efficient.
