Interactive Tools Make Classroom Video 更多的 Active Than Passive

Article Featured Image

A phase shift appears to be underway in the realm of educational video technology. On one side of this transformation, 教育视频的核心挑战是基本的和存在的:我如何制作它,我把它放在哪里? 另一方面,专业教师会提出一些问题:我如何以一种吸引学生兴趣的方式呈现材料,并鼓励他们在教学视频中思考?

初创企业和老牌供应商正在想出巧妙的解决方案,以实现与教育视频的互动. 将它们分为教师驱动型和学生驱动型是很有帮助的. 这个解决方案是否需要一个有远见的老师在准备教学视频时,煞费苦心地预测学生的需求? Then call it teacher-driven. 这个解决方案是否需要学生们把自己放在平台上,以驱动所有学校中最强大的力量——同伴压力? If so, it is learner-driven.

一个历史悠久的方法是允许教师构建选择你自己的冒险风格的讲座. 这些课程为学生提供了阅读材料的分支路径,这取决于他们如何回答老师在课堂上提出的问题,以探究常见的误解,并指导学生在继续学习之前了解他们需要了解的补习材料. 有两个平台采用了这一普遍的课程构建理念并构建了能够支持这一理念的视频体验: Eko贸易全神贯注的. Eko贸易是一个令人印象深刻的强大且免费使用的平台,可以使无限复杂, choose-your-own-adventure, 互动视频和展示其稳定的固体质量娱乐节目使用它. Eko贸易 doesn’t target education, 然而,据传其未来的主要收入来源是与沃尔玛合作,建立在线视频服务,与亚马逊和网飞竞争. 全神贯注的 is similar in functionality 和 significant in that the company was acquired by 创作, a hosting platform with a large footprint in the educational video market.

Taking a step down in sophistication, there are in-video quizzes that provide a similar experience for the student, but without any branching logic. Everyone sees the same video regardless of how they answer the questions, although they usually will get some feedback from the in-video question tool. 问题通常用来提醒学生注意接下来的内容,或者评估学生对问题之前内容的理解. PlayPosit和Edpuzzle是两家专门为YouTube或其他视频添加视频测验工具的公司. 许多学校使用的视频托管平台本身就支持视频测试,包括创作, MediaSite, 系综.

学习者驱动方法的趋势是从学生如何在线社交互动中获取线索,并试图将这些行为融入学生观看教学视频的方式中. 一个典型的例子是 弧媒体, the video hosting platform built by Instructure, the company behind the Canvas learning management system (LMS). Arc实现了类似于Soundcloud和Facebook Live的交互功能:每个视频都包含一个基于时间的聊天室, with threaded discussion posts by the class popping on as the video progresses. 由于Arc是由LMS供应商设计的,因此它是考虑到教室的需求而制作的. 该公司做对的一个细节是,它可以很容易地在视频使用的每个学期中检索评论:包括前几年学生的注释和聊天的视频看起来不真实和陈旧.

最后, 还有snapchat教育平台,利用短视频促进在线视频课堂讨论. In these, the teacher prompts students with a topic 和 the students respond with video. 一个例子是 回顾, offered for free by the makers of the Swivl camera platform. Flipgrid是另一个这样的平台,在被微软收购后也可以免费使用. 这两种方法都能让你的学生有机会与你和更接近他们的术语和舒适区的材料联系起来.

I’m agnostic as to whether either approach is superior. 当教师和学习者都投入时,所有的课堂技术都能带来最大的好处, but each will suffer when one or the other is taken away. 幸运的是,这些专门的工具现在可以让教师通过视频接触到不同类型的学生.
