ABSTRACT Addressing high demand for developmental math instruction and low rates of successful completing of the developmental coursework, with cost and space constraints, has been an ongoing challenge for postsecondary institutions. With advances in online instructional technology, particularly those based on artificial intelligence, web-based instruction is increasingly considered as a way to alleviate these burdens. This is among one of the first efforts that uses a quasi-experimental design to compare the academic outcomes of students who take a developmental mathematics course in a blended setting that combines face-to-face instruction with an online intelligent tutorial system, ALEKS, to the academic outcomes of students who take the same course in a fully online setting. Results suggest that students receiving online-only instruction perform worse on the final exam and receive lower course grades. However, a cost-effectiveness analysis suggests that fully online instruction has both a lower cost per student enrolled and a lower cost per student passing the course.

通过大学发展教育让学业准备不足的学生做好准备：课程交付形式重要吗？

摘要 在成本和空间限制的情况下，解决对发展数学教学的高需求和低成功完成发展课程的比率一直是高等教育机构面临的一个持续挑战。随着在线教学技术的进步，特别是那些基于人工智能的技术，基于网络的教学越来越被认为是减轻这些负担的一种方式。这是使用准实验设计比较在混合环境中学习发展数学课程的学生的学术成果的首批努力之一，该课程将面对面教学与在线智能辅导系统 ALEKS 相结合，以在完全在线的环境中学习相同课程的学生的学业成绩。结果表明，仅接受在线教学的学生在期末考试中表现更差，课程成绩也较低。然而，成本效益分析表明，完全在线教学的每位学生注册成本较低，通过课程的每位学生成本也较低。
