Find a Place for Live Video and Audio Streaming in the Classroom

点播流媒体已被证明是一项变革性的技术. Counterintuitively, 与传统广播行业的直接竞争对手相比,点播流媒体对该行业的颠覆性更大, live streaming. 而直播仅仅是另一种最初更糟糕的媒体传播方式, 按需服务催生了一种完全不同的消费和生产模式,这种模式正在接近将其前身退回到上一个时代的临界点. 消费者已经习惯了选择特定的视频材料 their tastes and available on their schedule, 而不是按照自己喜欢的节目的播放时间安排生活, as we did in previous eras. There are surprisingly few events compelling enough to watch live outside of sports; consider the contrived made-for-TV productions the major networks air today. A parallel challenge is finding a compelling use case for live, one-way video streaming in education, outside of para-educational, ad-hoc events like athletics, commencement ceremonies, or presentations by distinguished speakers.

考虑到未来的学生将出生在一个后掐线时代. 大多数人从来没有经历过换频道“看正在播什么”的经历,等着看完一场他们不太喜欢的演出,直到下一场演出开始, 或者和潜在的朋友讨论前一天晚上必看的电视节目. 他们会认为这是荒谬的不公平,你不能让电台播放你想要的歌曲,而不打电话给电台要求. 他们将在大众媒体转型的另一边长大,从昨天的有限菜单,广泛享受网络电视和广播节目,到今天几乎无限选择的个人媒体播放器, YouTube channels, 播客是高度专业化的每一个可能的兴趣利基. Not to set too dystopian of a tone, 但未来的学生只会知道他们自己设计的回音室.

我们的学生需要努力应对变革时代的社会成本,他们正在成长, 是什么导致了社群的缺失而社群的缺失是由实时共享的大众传播促成的. 前几代人有三个网络电视台和联合广播节目, unfortunately, crowded out non-mainstream, minority opinions and perspectives in their programming, 但无疑也为社会提供了一种凝聚力,具有广泛的吸引力, consensus viewpoint. 社区建立在共享经验的基础上:广播媒体在整个20世纪提供了一个重要的经验. 今天的学生将决定一种主流文化如何在21世纪得到滋养.

To demonstrate the existence of social benefits to live media, 我建议建立一个课程计划,围绕一个基于互联网的广播电台运行的班级使用 Icecast as the streaming server. 如今,许多广播电台都在使用冰播,但任何人都可以免费使用.

一个想法是让每个学生都写一段录音,试图说服听众改变他们对某事的想法. 你把它们串在一起,在一个连续的循环中播放. 然后,每个学生都会被要求定期收听电台, perhaps by setting aside 10 minutes of class time per week, 并评估他们碰巧听到的片段有多少改变了他们的观点. 这个作业将迫使每个学生主张一些他或她认为其他学生可能不同意他们的观点, 因为他们的目标是向你倾斜,而不是为他们和他们的同学已经同意的事情争论, 这将要求他们以一种他们认为对同龄人有吸引力的方式来组织他们的论点.

Hopefully, then, 这个练习将挑战学生们看到彼此的观点, 包括他们如何提倡和批评别人的观点. Furthermore, 这项技术的实时特性将迫使学生们在写评论的时候,容忍碰巧在播放的任何一部作品. 适度、宽容和愿意倾听是值得教导的公民美德. To easily set up a radio station, visit this GitHub site and get started with Icecast.
