在线课程开发与在线教学
学习成果


Reminding students of
the learning goals
(outcomes) at key
intervals helps students
to identify their
progress and to
understand why they
are performing certain
learning activities.
Let’s review our
outcomes. Rate 1-5 if
you believe we have
addressed the
outcome already.

每隔一段时间提醒学生
学习目标(成果)有助
于他们确定其进度,理

作业概要

Discuss the online
discussion
› How would you
describe the
discussion,
compared to a
face-to-face
discussion?

讨论“在线讨论”
> 与面对面讨论比较,
你会如何描述在线
讨论。
面对面讨论与在线讨论


How are they alike?
How are they
different?


它们有何相似之处
它们有何不同之处
面对面讨论




Immediate,
synchronous
Nonverbal
communication
Usually not graded
“Temporary” in
Nature




直接、同步
非文字交流
通常不评分
具有“临时”特性
在线讨论




Asynchronous
Mostly written
communication
Usually graded
Permanent written
record of what was
said




非同步
大多数情况下通过文字
交流
通常会被评分
所交流的内容以文字记
录永久保留
影响


Discussions are
important in both
learning
environments
However, we must
change the way we
structure and
facilitate discussions
online to achieve
the same quality, to
achieve the same
outcomes.

两种学习环境下的讨
论都是重要的。

但是,为达到和面对
面讨论同样的质量和
效果,我们必须改变
组织和促进在线讨论
的方式。
设计欠佳的在线讨论





Shallow
Narrow
Awkward
Can feel like “busy
work” (meaningless)
Can emphasize
speaking (writing)
over listening
(reading)





深度不够
面窄
令人尴尬
感觉像“忙碌的工作”
(无意义)
强调说(写)重于听
(读)
What are some qualities
that lead to poorly
designed online
discussions?
什么特性导致在线讨论设计欠佳
非强制的讨论

Online students don’t
often opt for optional
learning activities

在线学生不常选择非强
制的学习活动
教师缺席

Instructors making
the online discussion
forum for students
only

教师只为学生组织在线
讨论论坛。
宽松的参与策略

Not explaining when,
how, and where to
interact leaves
students
wondering … and
not participating

没有说明何时、如何、
在哪互动,使得学生感
到困惑且不参与。
封闭式问题

Asking students
close-ended
questions with
definite, concrete
answers leaves them
with not much to say

询问学生有明确、具体
答案的封闭式问题,使
得学生没有太多可说。
排队模式及回答模式

Answer One
Question and Reply
to Two Peers

回答一个问题,回复给
两个同行(同学)
排队模式存在的问题





Leads to repetitive
answers
Latecomers have
nothing to contribute
Invites plagiarism
Limits the scope of
the discussion
Has a purpose of
assessment instead
of discussion





不断重复答案
迟到的人失去回答的机
会
导致剽窃
限制讨论范围
意在评估而非讨论
替代:发起讨论


Instead of posting a
question that all
students must answer,
post a discussion
starter
Then, add follow-up
questions

用发起讨论的帖子替代
所有学生必须回答一个
问题的帖子

然后,添加问题
独立思考—结对讨论—交流分享

What was the most
interesting thing you
learned from the
readings this
weekend?

你从本周末的阅读材料
中学到的最有趣的事情
是什么?
教师在推动在线讨论方面的作用





Cheer students on; let
them know when they
are right
Highlight important
points
Question students; ask
them to clarify and
expand
Correct
misunderstandings
Provide direct
instruction
使学生振作起来,在他们
正确的时候要让他们知道
 突出重点
 向学生提问,要求他们澄
清并扩充回答
 对误解进行修正
 提供直接的指导

通过在线讨论教会学生批判性思考

Critical thinking is “the
intellectually disciplined
process of actively and
skillfully conceptualizing,
applying, analyzing,
synthesizing, and/or
evaluating information
gathered from, or
generated by, observation,
experience, reflection,
reasoning, or
communication, as a guide
to belief and action.”
~Michael Scriven and Richard
Paul

批判性思考是“积极地
、熟练地解析、应用、
分析、综合、评价所获
得的信息,这些信息来
自于观察、实验、思考
、推理和交流,并用其
指导信念和行动。”
通过在线讨论教会学生批判性思考


Online discussions
(when designed and
facilitated well) often
evoke more critical
thinking than inperson discussions
Let’s practice
evoking critical
thinking with each
other using Socratic
Questioning Prompts

在线讨论比面对面讨论
更能带动批判性思考
(特别是在设计和推动
工作做得好的时候)。

让我们运用苏格拉底式
提问带动批判性思考。
苏格拉底式提问



Small groups, choose
a speaker
Speaker, tell the group
about a hobby you
enjoy
Listeners, use the
Socratic Questioning
Prompts to get your
speaker to encourage
the speaker to think
more critically about
his or her hobby

分成小组,选出一名发
言人。

发言人,告诉所在小组
你的一个爱好。

听众,运用苏格拉底式
提问鼓励发言人对他或
她的爱好进行批判性思
考。
思考


Listeners: How did
the Socratic
questions affect
what the speaker
shared? What more
did you learn as a
result?
Speakers: How did
these prompting
questions affect your
thought process?

听众:苏格拉底式提问
如何影响发言人所分享
的内容?你从中更多的
学到了什么?

发言人:这些提问如何
影响你的思维过程?
对在线讨论评分
我们如何对讨论进行评分?




Frequency of
participation
Quantity (number of
posts, or number of
words per post)
Correctness of
expression
Quality

参与的频率

数量(帖子数量、帖子
的字数)

表达的正确性

质量
参与频率 — 独立思考,结对讨论,交流分享

Which do you
suppose is more
important?

你认为哪一个更重要?
A. 帖子的总数量
B. 学生参与的总天数

为什么?
A. The total number of
posts
B. The total number of
days on which
students
participate

Why?
Two speakers, one
counter
 For 5 minutes, speakers
engage in
conversation about
your hometowns
 Counters, tally the
number of times the
speaker changes from
one to the other
 In 5 minutes, how
many back-and-forth
exchanges were
there?


2个发言人,1个计数人

5分钟,发言人进行有
关家乡的谈话

计数人,计算发言人交
替发言的次数

5分钟内来回替换多少
次?
讨论帖质量评价:活动


In small groups,
discuss what a high,
medium, and low
quality discussion
post look like.
Together: Brainstorm
what “quality” looks
like.

分组讨论高、中、低质
量的讨论帖子是什么样
的。

集体讨论:头脑风暴,
“质量” 指的是什么。
一般情况下,讨论帖子的“质量”是什么意思?



Posts move the
conversation forward
Students demonstrate
their growing
understanding of
course concepts
Students demonstrate
that they are
completing and
understanding the
course readings

帖子促进交谈。

学生展示他们对课程
概念理解的程度。

学生展示他们对课程
阅读材料完成和理解
的情况。
质量指标
Students show that
they are reading and
considering other
posts, not just writing
 Students use
examples, offer
explanations, and
pose thoughtprovoking questions
 Students demonstrate
critical thinking


学生表现出他们不
只是写贴,也在阅
读或思考其他人的
帖子。

学生运用实例,进
行解释,提出值得
深思的问题。

学生展示其批判性
思考。

简单讨论
What is photosynthesis?
“How green plants use sunlight to
change carbon dioxide and water
into carbohydrates and oxygen.”
I agree!
Well said!

什么是光合作用?
“绿色植物利用太阳光
将二氧化碳和水转化成
碳水化合物和氧气。”
Me, too.
我同意
说得好
我也同意
通过FlickrPoet或其它图片网站进行讨论
光合作用
阳光
氧气
原创讨论帖——受到图片的启发

Photosynthesis, in this
picture, is a magical,
complex process that
happens everywhere,
all around us. You put
in sunlight and water,
and then stand back
like this guy in the
picture, and you get
carbohydrates and
oxygen. It’s kind of
amazing, but in this
picture, it’s in the
middle of an ordinary
field, showing that it’s
extraordinary and
ordinary all at the same
time.

在这张图片中,光合
作用是一种神奇的、
复杂的过程,这个过
程在我们周围的每一
个地方都在发生。只
要你提供了阳光和水,
然后像图中的那个人
一样,站在一旁,你
就会得到碳水化合物
和氧气,这很不可思
议。图片中的普通田
野上,显示出其平凡
和普通。

The second picture shows a
musical instrument. The
instrument itself doesn’t
make the music – you
need someone to actually
play it. You need that
energy. And you take that
person’s movements and
combine it with the
instrument, and out comes
music. Likewise,
photosynthesis takes
sunlight and water and
changes it into
carbohydrates and oxygen.

这张图向我们展示了一个
乐器。这个乐器自己并不
能发出音乐——需要有人
去演奏。你需要能量。那
么,你得让这个人拿着乐
器动起来,音乐便一泻而
出。同样,光合作用就是
把阳光和水转化成了碳水
化合物和氧气。

The third picture shows the
valve on an oxygen tank.
To me, this shows that we
can bottle up what
photosynthesis produces
and use it. This process is
valuable, very valuable, to
human beings.

第三张图片是氧气罐的阀
门,对我来说,它表现的
是我们能够将光合作用的
产物装入罐中。这个过程
对于人类来说非常非常有
价值。
