有效的学习呼唤高效的课堂。然而,在当前高中化学课堂的各个环节之中都或多或少的存在着一些低效因子,如师生的定位不合理、设备软件的运用不合理、教学方法的选择不合理以及教师的知识结构不合理等,这些低效因子俨然已经成为建构高效课堂的“绊脚石”。找准诱因,去除低效因子,建构高效课堂已经成为广大高中化学教师的共同呼声。 Effective learning calls for efficient classrooms. However, there are some inefficient factors in the current high school chemistry classes in all aspects, such as the irrational orientation of teachers and students, the irrational use of equipment software, the improper choice of teaching methods and the teachers’ knowledge Irrational structure, etc. These inefficient factors have become “stumbling blocks” for building efficient classrooms. Identify incentives, remove inefficient factors, the construction of efficient classroom has become the common high school chemistry teacher’s voice.
