混合学习是一项正式教育方案，学生学习时至少有一部分要通过内容和授课的在线传递进行，并且在某种程度上能够控制时间、地点、途径和/或进度，同时至少有一部分要在一个远离家中的有监督的实体场所进行。

混合学习没有统一的标准化门槛，并不是有效的混合才能叫混合学习，混合学习既可以是有效的，也可以是无效的。混合学习中存在的一些急需解决的困难，它们有可能会影响混合学习的效果。

Blended learning is a formal education program in which a student learns at least in part through delivery of content and instruction via digital and online media with some element of student control over time, place, path, or pace. While students still attend "brick-and-mortar" schools, face-to-face classroom methods are combined with computer-mediated activities. Blended learning is also used in professional development and training settings.
