在线多媒体教学利器-bigbluebutton – The online multi-media teaching system

最近以来,有越来越多的学生找上门来学习英语,这点让热爱教学的我甚是高兴,可转念想想外出给学生上课时的种种旅途奔波,堵车,粉尘和涨了价的出租车,又让我望而却步,相信科技能改变教学的我,又开始了新一轮的探索,最后让我发现了免费实现多媒体远程教学的利器-bigbluebutton.同之前推荐的软件一样,这也是一枚开源代码,可以安在ubuntu 10.04服务器上。

Recently,there are a number of students approaching for tutoring of the English language. Given that I like teaching,whenever to think of the bad traffic,tough journey,and unpleasant air quality,I have to surrender.I,who firmly believe the magic of technology,launched another round of exploration. And Bigbluebutton came to my mind. An opensource multimedia online conferencing script to be installed on linux server for free.

我们先来看看它的主界面:

Let’s take a look at the UI:

经典的三栏设计:从左到右依次是控制栏,演示栏和聊天栏。

Classical Three columns style: namely controlling,presentation,and chatting.

控制栏可以起到控制教室和点取学生发言的功能,控制栏的最底下,可以播放教师,或者被教师选中的听课学生的视频图像。演示栏内可以播放各种文件,包括常用的PPT,PDF,DOC甚至是视频音频等文件。在这里播放的文件可以由教师控制,并且向全部学员广播。第三栏是聊天栏,可以进行点名,签到,和解疑答惑等实时沟通。

The controlling center at the left columns enables the teacher to choose specific student’s input to be broadcasted to the rest,at the bottom of which is a video layout. Teachers could decide to broadcast any specific webcam of a student.The second column is used to broadcast files like PPT,PDF as well as audio and videos, under the teacher’s control. The very right column is for chatting and taking attendence.

Bigbluebutton具备了在线授课所需要的所有功能,并且开发者还不断地在开发新的版本来支持更多的功能。目前Bigbluebutton可以和moodle融合的非常好。也就是说,在moodle教学管理系统注册的所有学员,都可以直接参与bigbluebutton在线课堂而不需要再次注册。

Bigbluebutton provides all the fuctions to facilitate online teaching, and its developers are commiting to add more features in the future releases.Bigbluebutton integrates perfectly with Moodle,that is to say moodle users are able to join the online classroom directly from their regiestered courses.

教师可以控制是否让学生单独启动在线课堂,如果学生不被允许自行启动,他们将会得到等待教师加入的提示。

Teachers are able to decided whether students are able to initiate an onlinte classroom, if they are not, they will be notified to wait for the teachers to join in.

总结起来,今后我将会尽量的将我的学生都转换成在线授课模式,这样老师省去的路途劳顿,并且学生也可以借助服务器的快照再次复习老师的授课内容。

All in all, from now on, I will be transfering my students to this online teaching mood, so as to save time. The students would also be able to review the courses from the snapshops on the server.

如有任何同事也对此感兴趣,欢迎一起交流bigbluebutton的一些使用心得。为防止垃圾邮件,请根据下面的提示找到正确的邮件地址。

英语教师的利器-audacity

像我一样的英语教师们经常在出试卷的时候遇到各种难题,尤其是听力。由于大部分情况下我们都不具备自己邀请专家,到专业的录音棚录制听力材料的能力,所以我们不得不使用我们手边的一切资源,包括网上down来的对话,各种复习题集中编辑的好的听力材料等等,但是问题来了,要让其他地方事先录制好的听力Mp3音频材料变成自己考试当中能用的音频材料,我们便需要一款音频编辑软件。

说到这,大家都会觉得有 cooledit,甚至有它被adobe收购之后发行的新版本Adobe Audition。cooledit由于被收购,已经很久没有更新,上一个版本发布时,还是Windows XP盛行的时代,导致它与新的操作系统Window7和Windows8存在严重的兼容性问题。如果说使用更新版的adobe audition,兼容性问题倒是解决了,但是接踵而来的就是另一个问题,费用。我相信中国的英语老师里,或者是中国的英语学校中会花上一万多人民币购买授权的应该比较少,所以可能很多的老师正在“被迫”使用X版,不过现在好了,向大家介绍一款超级强悍的替代软件audacity,这款软件开源,永久免费,并且功能强大,为什么试试呢?

一,主界面

audacity主界面
audacity主界面

由于是开源软件,社区的支持让软件拥有较为完整的汉语界面(给非英语老师使用)。另外,主界面的操作部分与我们之前所熟知的cooledit和audition差别不大,可以看到立体声的主音轨,和菜单界面里的音频编辑功能。

下面我主要说说,制作英语听力考试文件的时候所需要的一些基本功能。

 

二,听力考试音频材料编辑

1,导入要编辑的音频

在文件,的打开选项中可以在电脑中浏览到自己想要编辑的音频文件。

audacity导入音频

在控制工具控件的第一个控件,选取控件

audacity选取控件
audacity选取控件

处于被激活的状态时,就能选取相应区段的音频,例如:

选取区段

被选取的区段可以直接再在文件菜单中导出,或者也可以使用编辑-剪辑边界中对音频加以分割,从每个音频材料中选取到合适音频资料后再通过编辑,编辑边界中的合并功能,可以将选取的分段音频材料合并成文件加以导出。

三,关于保存MP3文件

由于MP3格式所采用的编码标准并不是开源的,所以当我们需要保存MP3格式文件时,必须安装一个含有私有编码格式的Mp3保存插件,但是这个过程非常简单,直接按照跳出来的提示,点击进入下载安装就能解决。当然,你也可以选择把你的听力考试音频材料保存为其他开源音频格式。

第一次先介绍到这里,下一次再介绍关于自己录制部分考试说明时所要使用的相关软件功能,敬请期待。

 

 

 

 

 

 

iSpring makes the teaching Job easier iSpring 学习套件介绍

我是陈庆华,我在中国北京市二十一世纪高中教英语。一次偶然的机会,当我正在网站上搜寻如何充实我moodle学习网站damienglish.com学习内容的时候,我发现了一位老师发表在一个教学论坛上的帖子,他强烈推荐iSpring Suite软件。我便浏览了iSpring公司的网站,下载了一份试用版软件。我已经无法形容我第一次使用软件时有多么兴奋,我突然觉得之前PPT给我带来的所有困扰和尴尬,都将因为这样一个强大的产品而一瞬间成为过去。

不知你是否有过这样的经历,你非常认真的做好了PPT,还插入了会令你的听众非常愉悦兴奋的视频和音频,可是当你站在台上发表演讲的时候,你不得不顶住所有尴尬,在文件夹中找来找去,以让你的视频能够播放,而这时,听众们早已失去了兴趣,而且他们还认为你并没有认真准备你的演讲。你是否还有过这样的经历,尽管你有很好的演讲技巧,但是你还是没有能够用一页页静止的PPT页面来打动你的听众,而让他们不感觉无聊。

作为一名教师,每天都跟PPT打交道,每天都要做演讲,这样的经历曾经一直困扰着我,知道我找到了这样一个终极解决方案,那就是iSpring Suite.

让我来简单的告诉你我最看中的两大功能

在过去,如果我需要准备课程,我必须做好PPT。但是因为我是语言教师,听力材料,和视频材料是我课堂里所必需的,我需要用他们来训练学生的听力,每当我做这件事的时候,我就必须特别注意以下几点:

1, 视频和音频文件的路径。

2, 因为我需要在视频或者音频播放的过程当中来控制播放的进肚,所以我不得不使用右图所示的VBA界面来完成插入音频和视频的过程,但是对于我这样和其他许多不太懂得编程技术的老师来说,实在是很有难度。

3,当这一切都完成的时候,我还要把所有的PPT和相关的文件都拷贝到我的U盘里面。

4, 在上课之前,我必须提前到教室去,一个个的修改PPT中视频和音频文件的路径,使他们能在教室的电脑上正常播放,这是一件非常麻烦而且容易出错的工作。

而且有时候两台电脑的PPT版本不一致,就又会带来更多的麻烦。

作为一名语言教师,我每堂课里面多的可以有十多则听力材料要播放,这样一个个的更改真的是十分的费时费力。

但是现在,有了iSpring带来的发布功能,准备课件就变得非常简单了。想知道我现在是怎么做的么? 我直接在PPT里面插入音频和视频,以及动画等其他的内容,然后我直接在iSpring Suite上面点击发布,这样我所有的课程内容都被自动的打包成了一个SWF的flash格式文件,我可以在任何的地方播放它,而不用再去考虑路径和文件的问题了。我所有的难题都一下子迎刃而解了。我现在还可以把我制作好的课程文件分享给我的学生们。他们比我更喜欢这样的一个强大的功能,因为他们可以拿回家去,自己好好复习已经学过的内容。

我还想谈谈关于iSpring的几点好处:,

1,有了iSpring Suite,我可以非常简单的创建或者转换我的演示文稿成为PPT文件,在转换之前,我还可以看根据自己的需求设定好我所需要的视频和音频的清晰程度。这一切都能在设置里面轻松实现。

2, 因为我还为我的学生开始了一个英语学习的moodle站点,所以我很需要iSpring 给我的带来的另外一项激动人心的功能,他能够帮助我充实我网站的内容,它让我的网站变得更加的具有学习意义。而利用iSpring所制造出来的课件,都是兼容SCORM的。你可以看看下面图中,我的网站:

3, 漂亮的quiz creator也是我非常喜欢的一个组件,因为他能把我从繁重的改作业的负担中解脱出来,让我的工作更加有效率。我之前有段时间每周都个要改上百份学生叫来的作业,而且之后还要花上另外的好多个小时来统计考试数据和做总结。现在就轻松多了,有了iSpring Quiz Maker 我就可以非常简单的做出在线测试,而且这样的测试互动性非常强。学生们也都觉得这样的在线测试,比起传统的在纸上进行的测试更能让他们接受。另外,测试的成绩会自动生成,而且被记录下来,我只要好好分析学生的成绩来指导教学就可以了,是不是非常精彩?

现在还有一些iSpring Suite的功能,我还不太会使用,我任务我可能需要花一点点时间来阅读iSpring网站上提供的学习资料,但是到目前为止,我已经确信iSpring Suite就是那个我需要的产品,它极大地便利了我的教学工作,我非常的赞赏iSpring公司他们的创造力和所做出的贡献,他们的努力便利了我们教师,会让我们的教育变得更加成功。

北京

My name is Qinghua Chen. I teach English at Beijing 21st Century High school in China. Recently, when I was searching solutions on putting contents on my moodle site, Damienglish.com, I came across a post in teacher’s forum, strongly recommending iSpring products. I visited the website of iSpring, downloaded a trial version of the product, and I can’t tell how excited I was when using the products for the first time. I just felt all my previous troubles and embarrasement I had with PPTs were in the past, with the installation of this amazing product on my computer.

Have you ever experienced a sutiation when you have prepared carefully edited PPTs with rocking videos and audios, and when get to presenting you are embarrassed, struggling from folders and urls to make your videos play? The audience is becoming impatient and starts to think that you haven’t prepared well. Have you also experienced that even with your great presentation skills, your audience becomes bored of static PPT sides with nothing but words and figures?

As a teacher, who uses PPTs and does presentations every day, those things troubled me most in the past, until I found the ultimate solution, the powerful iSpring Suite!

Let me tell you here about two great personally benefits I got from iSpring Suite.

iSpringflash

In the past, while editing my PPTs to prepare for a class, I needed to present with audio and video listening exercises to facilitate my class with listening comprehension capability, since I am a language teacher. But there are several matters I need to pay great attention to:

1) The url of the video/audio

2) Since I need to control the playing I have to use VBA, like in the picture, which is very confusing for non-technicians like me and many other teachers who focuses mostly on their teaching rather than programming.

3) When this is done, I need to copy all the PPTs and related files to an USB dirve.

4) But before I start the class, I need to get in the classroom five minutes earlier and re-edit the urls to match the properties in the classroom computer, which is again very confusing.

And when the versions of PowerPoint don’t match on two machines, other unknown errors may appear.

As a language teachers, I sometimes need to do this ten times during a single listening section to make each of my listening tracks work on every slide, which is painstaking.

But now, with the publishing facilities of iSpring Suite, presenting a class has for the first time becomes so easy!

You know what I do now? I insert the videos, audios, pictures and animations in the PPT and then I publish the presentation with iSpring Suite. Then – magically – a single SWF Flash file is created with all the content of my class inside! I need this file only to teach the class, and all the preview troubles are solved. All the videos and audios plays perfectly!

My students enjoy this function even more than I do, becuase now I can simply distribute the Flash file and they can review their classes with all the exercises at home with just a single click. They can also view the notes and answer.

2) With iSpring Suite, the created Flash files are very easy to be optimized according to my own preferences. If I would like to have a higher quality of the video in my presentation, it can all be tweaked. This actually helped me a lot. Now I can choose the quality myself depending on what I need that video for.

3) I have a moodle website at school to help my students’ learn online, and with iSpring I definitely made my moodle site more meaningful thanks to the great interactive courses iSpring Suite helped me to create and publish. And what’s better – iSpring’s courses are SCORM compatible. Take a look at my site:

With iSpring, my site has become more powerful, and my students really enjoy this type of learning and reviewing material. Plus, it’s more eco-friendly.

iSpringquiz

4) The elegant quiz maker helped me to test students in a much more effective way. I used to grade hundreds of papers every week and spend serveral more hours to do the statistic and write the review. But now, with the quiz maker in iSpring Suite, writing and giving exams is not longer a burdern for me. Students seem to enjoy these interactive quizzes much more than normal paper-based tests. Look at one of the listening comprehension quizzes I created for my students – a typical spot dictation test. The result will be shown to students, paper will be graded and grades will be tracked automatically. This is nothing but amazing!

There are more features in iSpring Suite that I am not familiar with, and it will take me some time to go through the knowledge base on the iSpring website to learn them. Anyway I am convinced that iSpring Suite is exactly the product I wanted to facilitate my teaching as a Language teacher in China and I really appreciate the creativity and devotions of the iSpring company to have brought teachers powerful products to make our education more successful.
