Online Education

在线教诲

Good morning, everybody.

各人早上好。

In today's lecture, we will talk about online education.

明天的讲座,我们要谈一谈在线教诲。

You know, in some parts of the world, it is not that easy for people to receive education.

各人都晓得,在有些中央,受教诲依然不是件容易的事。

And even in the United States where education is available, it might not be within reach.

即便在美国如许的教诲大国,受教诲能够也有困难。

Thus, online courses provided by those world-famous universities can bring the best quality education to as many people as we could around the world, and for free.

因而,天下着名大学提供的在线课程,就可以为天下上许很多多的人带来优质教诲,并且是收费的。

First, let's talk a little bit about some of the components that go into online education.

起首,我们谈一下在线教诲的几个特点。

The first component is that when you move away from the constraints of a physical classroom and design content for an online format, you can break away from, for example, the one-hour lecture format.

第一个特点便是在线教诲冲破了实体讲堂的限定。设计在线课程内容的时分,教员可以抛开许多限定,比方一小时的课程时长。

You can break up the material, for example, into short, modular units of 8 to 12 minutes, and each of the short units introduces a coherent concept.

举个例子,你可以将讲课资料分红8到12分钟的小单位,每个单位引见一个完好的观点。

Students can deal with this material in different ways, depending on their backgrounds, their skills or their interests.

先生可以依据本身配景、技艺和兴味,以差别的方法学习资料。

So, for example, some students might benefit from a little bit of preparatory material that other students might already have.

比方,有些先生能够会从预备资料中学到工具,而这些资料其他同窗早就有了。

Other students might be interested in a particular topic that they want to pursue individually.

其他同窗能够会对他们本人喜好探求的详细话题感兴味。

So this format allows students to break away from the one-size-fits-all model of education, and allows students to follow a much more personalized curriculum.

以是,这种方式将先生从“一刀切”式的教诲中束缚出来,先生们得以学习特性化的课程。

Second and perhaps one of the biggest components of our online education is that when we need to have students who practice with the material in order to really understand it.

第二个,也是在线教诲最大的一个特点,便是我们需求让先生有资料训练,如许才干确保他们真正了解了所学内容。

There's been a range of studies that demonstrate the importance of this.

很多研讨表现了这一点的紧张性。

A study in Science last year, for example, demonstrates that even simple retrieval practice, where students are just supposed to repeat what they've already learned, gives considerably improved results on various achievement tests.

比方,客岁《迷信》杂志的一项研讨表现,就连只需修业生复述所学内容的复杂检索训练,都进步了很多成果检验中先生的成果。

So, we need to build in much more meaningful practice questions.

以是,我们需求体例更故意义的训练标题。

Now, fortunately, technology has helped us to provide the students with feedback on those questions.

侥幸的是,如今技能提高了,我们可以就题目向先生反应。

We can now grade a range of interesting types of homework online.

如今还可以给很多风趣的在线家庭作业打分。

The third component is what is called collaborative learning.

第三点是协作学习。

Students could collaborate in different online courses in a variety of ways.

先生可以以种种方法在差别的在线课程中协作。

First of all, there was a question and answer forum, where students could pose questions, and other students could answer those questions.

起首,在线课程会有一个问答论坛,先生可以在论坛上发问题,其他先生答复。

And what is really amazing is that, because there were so many students, it means that even if a student posed a question at 3 o'clock in the morning, somewhere around the world there would be somebody who was awake and working on the same problem.

最巧妙的是,由于先生许多,即便有人清晨三点提出题目,天下上另一个角落也会有还没睡的先生,一同处理这个题目。

And he might answer that question.

能够他就能答复谁人题目。

And so, in many of the online courses, the median response time for a question on the question and answer forum was 22 minutes.

因而,很多在线课程中,问答论坛上题目的呼应工夫少数在22分钟。

So in a word, if we wanted to offer top quality education to everyone around the world for free, what would that affect us?

总而言之,假如为全人类收费提供高质量教诲,将有哪些影响?

Three things.

我以为有以下三点。

First, it would establish education as a fundamental human right, where anyone around the world with the ability and the motivation could get the skills they need.

起首,在线教诲将教诲作为根本人权,全天下可以并且想要学技艺的人都能学到所需技艺。

Second, it would enable lifelong learning.

第二,在线教诲使得终身学习成为能够。

It's a shame that for so many of us, learning stops when we finish high school or when we finish college.

我们当中许多人高中结业或许大学结业之后就不再学习了,真是令人汗颜。

By making this amazing content available, we would be able to learn something new every time we wanted, whether it's just to expand our minds or it's to change our lives.

有了在线教诲这个巧妙的工具,我们想学新工具就可以学到,可以开阔视野,也可以改动人生。

And finally, this would make a wave of innovation possible, because amazing talent can be found everywhere.

最初,在线教诲也鼓舞了新一轮创新海潮,由于出色人才将到处可见。

To sum up today, we have talked about some features of online education and it's benefits.

明天的演讲,我们次要讨论了在线教诲的很多特点和洽处。

We are sure that online education will have a promising future.

在线教诲肯定出路黑暗。

In the next lecture, we're going to learn how online education has changed people around the world.

下次讲座我们会讲到在线教诲是怎样改动众人生存的。
