在工科教学中,工程知识碎片化严重影响了学生的学习效果,阻碍了对工程知识的有效建构。应强化知识综合,不断关联工程背景、相关学科知识。工程专业的学习置于工程问题空间,将工程问题贯穿于工程知识建构过程,以解决工程问题为导向。采用探究式学习方法,将知识学习与研究问题相结合,以分析、研究和解决工程问题的过程为平台,进行工程知识的关联与综合,帮助学生实现工程知识的整合与重构。 相似文献

在滇西岔河离子吸附型稀土矿调查评价、普查的基础上,对中山地貌区离子吸附型稀土矿探矿工程的布置与编号方法进行了总结。预查阶段不必按照勘查网布置探矿工程,探矿工程用“工程类型代号+施工顺序的流水编号”的方法进行编号。普查第一阶段的探矿工程数量占普查阶段总数的1/3~1/2,按矩形网布置探矿工程,用“工程类型代号+主勘查线编号+次级勘查线编号”的方法进行探矿工程编号。普查第二阶段的探矿工程数量占普查阶段总数的1/2~2/3,按树形网布置探矿工程,用“工程类型代号+树枝编号+树枝上的探矿工程编号”的方法进行探矿工程编号。详查、勘探阶段在普查第二阶段树形网的基础上增加探矿工程,探矿工程编号的方法与普查第二阶段相同。研究中山地貌区离子吸附型稀土矿的探矿工程布置与编号方法,有利于合理地布置和管理探矿工程,最大限度地发挥探矿工程对矿体的控制作用。 相似文献
