网络环境下本科生学习成绩下滑原因探析

Reasons for internet use and collegiate academic performance decrements

从2011年的电子阅览室的统计资料中,筛选出连续上网超过12h经历的读者,并按其学习成绩,区分为及格者、不及格者和受学业警告处分者,以不足12h读者为对照归纳了这4类读者群体的阅读时间的频率分布及其特征。又将具12h以上经历读者的学习成绩的平均分、绩点、班级排名和相对排名,按传统农科、分子生物学、非农学科区组考察不同专业的特点。结果表明:超过12h读者的上网人次仅占3.7%属于少数人群,其平均每次上网时间超过3.3h,而未曾达到12h的读者仅1.75h,成绩不及格者和受到学业警告处分者则更长。新设专业的学生比传统农科沉溺网络的比重大,并从流连网络与学习无力化角度,分析了沉溺网络和学习成绩落后的相互关系。
