培养基含水量对平菇抗杂菌能力胞外PH值及生物转化率的影响

本实验证明，培养基含水量70％有利于提高菌丝的抗杂能力，有利于提高生物转化率，且胞外PH值下降最迅速。培养基含水量在75％以下时，含水量越高出菇潮次越多。培养基含水量过高过低是影响杂菌污染率的最主要因素之一。建议实际生产中培养基含水量在65％－75％之间较为适宜。

Representational Issues in Students Learning About Evaporation

This study draws on recent research on the central role of representation in learning. While there has been considerable research on students’ understanding of evaporation, the representational issues entailed in this understanding have not been investigated in depth. The study explored students’ engagement with evaporation phenomena through various representational modes. The study indicates how a focus on representation can provide fresh insights into the conceptual task involved in learning science through an investigation of students’ responses to a structured classroom sequence and subsequent interviews over a year. A case study of one child’s learning demonstrates the way conceptual advances are integrally connected with the development of representational modes. The findings suggest that teacher-mediated negotiation of representational issues as students construct different modal accounts can support enriched learning by enabling both (a) richer conceptual understanding by students, and (b) enhanced teacher insights into students’ thinking.     

“九五““十五“期间江苏省成人高等教育数据分析与思考

对“九五”以来江苏省成人高等教育毕业生注册数据的统计与分析结果表明,十年间江苏省成人高等教育总体规模呈上升趋势,其中本科生所占比例持续上升,专科生比例下降;毕业生均龄亦呈上升态势;普通高校成教毕业生数量增长较快,本科成教增速尤为突出。“十五”期间成教没有出现低龄化现象,年龄段分布呈均衡化趋势。在江苏建设“教育强省”进程中,成人高等教育必须加强,特别要重视加快独立设置成人高等学校的发展。
