随着新课程的不断改革和深化,对高中化学教学越来越重视,化学课程作为高中教学的重要组成内容,不仅是学生掌握化学基础知识的难点,同时更是高考中的重点内容,在学生学习中占有着重要的地位。所以,老师能够精确地掌握教学难度,合理降低教学的难度,可以在提升教学质量的同时,有效提升学生对化学基础知识的掌握能力。基于此,本文以“水溶液中的离子平衡”作为例子,适当分析高中化学教学中,老师如何有效把握教学难点,提升教学有效性。
With the constant reform and deepening of the new curriculum, more emphasis is placed on chemistry teaching in senior high schools. As an important part of senior high school teaching, chemistry courses are not only difficult for students to master the basic knowledge of chemistry, but also are the key contents of the entrance exam. Learning occupies an important position. Therefore, the teacher can accurately grasp the difficulty of teaching and reasonably reduce the difficulty of teaching. In addition to improving the quality of teaching, the teacher can effectively enhance students’ abilities to master the basic knowledge of chemistry. Based on this, we take “the ion balance in aqueous solution” as an example to properly analyze how teachers can effectively grasp the difficult teaching and improve the teaching effectiveness in high school chemistry teaching.
