基于问题指向型的土壤地理课例研修初探

Preliminary study on the lesson study of soil geography based on problem orientation

土壤地理是高中地理教学新增内容.本文在论述开展问题指向型课例研修必要性的基础上,指出土壤地理课例研修的焦点问题应包括2个方面,即土壤地理知识的综合性和土壤地理课例研修的有效性.在课例研修过程中,教学内容的选择涉及土壤野外观察、土壤标本的使用和土壤的形成过程.教学中应坚持成土因素、成土过程和土壤属性的统一,明确土壤形成因素与自然地理要素的不同,注重对土壤学基础知识的系统理解,以感性认识激发研修活动的潜能.

Soil geography is a new content of high school geography teaching.On the basis of discussing the necessity of the problem oriented lesson study,the two focuses of soil geography are pointed out,comprehensiveness of soil geography knowledge and effectiveness of soil lesson study.In the course of lesson study,the selection of teaching content involves the field observation of soil,the use of soil samples,and the formation process of soil.The unity of soil forming factors,soil forming processes and soil properties should be insisted on teaching,the differences between soil forming factors and natural geographical elements are identified,the systematic understanding of basic knowledge of soil science is emphasized to stimulate the potential of lesson study activities with perceptual knowledge.
