The Benefits of Blending Learning
Blended learning is not new.However,in the past,blended learning was comprised of physical classroom formats,such as lectures,labs,books,or handouts.Today,organizations have a myriad of learning approaches and choices.The concept of blended learning is rooted in the idea that learning is not just a one-time event-learning is a continuous process.Blending provides various benefits over using any single learning delivery medium alone.
Extending the Reach
A single delivery mode inevitably limits the reach of a learning program or critical knowledge transfer in some form or fashion.For example,a physical classroom training program limits the access only to those who can participate at a fixed time and location,whereas a virtual classroom event is inclusive of remote audiwnces and,when followed up with recorede knowledge objects(abil-ity to playback a recordedlive event),can extend th reach to those who could not attend at a specif-ic time.
Optimizing Development Cost and Time
Combining different delivery modes has the potential to balance out and optimize the learning program development and deployment costs and time.A totally online,self-paced,media-rich,Web-based training content may be too expensive to produce(requiring multiple resources and skills),but generic off-the-shelf WBT,documents,case studies,recorded E-learning events,text assignments,and PowerPoint presentations(requiring quicker turn-around time and lower skill to produce)may be just as effective or even more effective.

混合型学习的优势
混合型学习并不是一个新概念.但是,过去我们所说的混合型学习是由一些发生在教室里的具体教学模式组成的.这些模式包括讲授、试验、书本以及讲义等.现在,一个组织有成千上万种学习方法可供选择.混合型学习的概念植根于这样一种思想:学习不是毕其功于一役的事情,而是一个连续的过程.比起单纯使用某一种传授媒介的方法,混合型学习法能够带给我们更多的好处.
扩展学习范围
毋庸置疑,单纯使用一种传授媒介的方法限制了一个学习计划所能够涉及的范围,使学习者难以获得某些以特定形式才能传达的知识.举例来说,对于教室中的培训计划,只有那些能在固定时间和地点上课的学习者才能参与.虚拟教室项目则不同.它将远程听众纳入其中,同时有录制资料跟进(能够反复播放授课内容).这样一来,那些不能按时上课的学习者也能参与其中了.
时间和成本的优化配置
将不同的传授媒介相结合,人们便有可能衡量和调整学习计划,对实施和开展这一计划所需的费用和时间进行优化配置.一个纯粹的在线学习计划可能步调灵活、资源丰富,但这种网络学习的内容也许生产成本过高(它需要多种资源和技术).但是一般的即时教学,类似文案、案例研究,录制下来的电子学习资料、课堂作业、ppt演讲(这些要求较短的反馈时间但是生产成本较低),这些方式可能和在线学习同样有效,甚至效果更好.
