摘要
针对教学实际中发现学生眼高手低、只知其一不知其二的问题,以二氧化硫的教学为例,提出基于生产、生活中有关二氧化硫的真实情境为背景来组织课堂教学。在教学中,依照"提出问题、师生活动、学生交流汇报、教师释疑解惑、共同总结整理"的程序实施教学,在细化了的、有目的的、多方位的有序互动中,充分激发学生的好奇心和求知欲,完善学生的知识结构,培养关键能力,形成必备品格。
As a discovery from the teaching practice in the past,students commonly only know the answers to the "what"questions but not the "how"nor the "why",and often aim high but lack of the skills to achieve such goals.Adapting the teaching of sulfur dioxide as an example,this article proposed a classroom teaching method which resided in the context of real life and industrial production scenarios where sulfur dioxide was involved.The teaching ran through the following procedure step by step:teacher and/or students raised questions;mutual interactions between teacher and students;students' presentations and sharing of thoughts^teacher cleared the questions and doubts;teacher and students summarized conclusions in the end.Through such refined,purposeful and multidimensional interactions during class,intrigued students^curiosity and thirst for knowledge,and enriched their knowledge structure,cultivated beneficial and necessary learning skills in the future studies.
