题目解答
答案
C. There is no mechanism to ensure that they make the required effort.
解析
本题考查对在线教育辍学率原因的理解,核心在于识别影响学生坚持学习的关键因素。解题需抓住以下要点:
- 在线学习的特性:缺乏传统课堂的外部约束机制;
- 学生行为驱动:自主学习能力与外部监督的关系;
- 选项对比:区分直接原因(如机制缺失)与间接影响(如互动不足)。
选项分析
A. 学术标准不严格
学术标准松散可能导致课程质量下降,但学生辍学更多由主动投入不足引发,而非课程难度本身。此选项为间接因素。
B. 评价系统薄弱
评价系统影响学习效果评估,但若无机制确保学习过程,即使评价合理,学生仍可能放弃。此选项未触及核心问题。
C. 缺乏努力保障机制
在线学习高度依赖自我驱动,若无签到、作业检查等机制,学生易拖延或放弃。此选项直接指向辍学的核心原因。
D. 缺乏课堂互动
互动不足会影响学习体验,但坚持学习更依赖内在动力与外部约束。若学生有明确监督,仍可克服互动缺失。
结论
机制缺失(C)是在线学习辍学的核心原因,其他选项均为辅助性影响因素。
