我简单给大家分享一下
I'd like to share with you

我在C++语言程序设计这门课中
several examples of blended-learning-based Rain Courseware

使用混合式教学模式的
I used for the course entitled

几个雨课件的样例
"C++ Program Design."

那整个这个教学模式的设计
For the design of this entire teaching method,

我是首先一门课肯定是以教材为基础
the first thing I consider is that a course must be based on textbooks.

这一点是我个人的观点
That's my personal opinion.

即使有了慕课有了雨课件
Even with MOOCs and Rain Classroom Courseware,

但是你不能没有一本主要参考书
you still need a main reference book

或者教材
or textbook.

当然有多本参考书是更好
Multiple reference books would be better,

但至少有一本主要参考书
but you need at least one reference book.

所以以教材为基础
So my course is based on textbooks,

或者你叫做以参考书为基础也可以
or based on reference books.

然后以面授讲课为主要的讲课方式
The main teaching approach is teaching face-to-face.

因为我们说的这个雨课堂也好
Because both the Rain Classroom

慕课也好
and MOOCs

是把它用在混合式教学模式中
need to be used in the blended learning method

完成校内教学任务这件事
so that the teaching tasks can be complete on campus.

所以面授还是主要讲课方式
So the main teaching approach is based on face-to-face teaching.

然后以雨课堂+慕课资源作为助力
Then the teaching activities are assisted by the Rain Classroom and MOOC resources.

这是我设计教学模式的一个主要的思想
That's one of my main ideas for designing teaching methods.

首先我们来看一下
First, let's talk about

通过雨课堂来推送预习复习和自学材料
the preview, review and self-teaching materials sent through Rain Classroom.

预习材料
The preview materials,

刚才说了是了解新课的大致内容
like I said before, are used to learn a new lesson's general content

学会简单的一些语法规定
and some simple grammar rules,

为迎接新的知识
and to mentally prepare for the new knowledge

这些需要进行一些思考和准备
to be learned.

那我们来看这个预习讲稿的一个样例
Let's take a look at an example of a preview lecture script.

这个是我讲函数这一个部分内容的时候
This is a preview lecture script I gave my students

给学生的一个预习讲稿
when teaching functions.

让学生通过这一页想让他理解
I wanted my students to understand

利用函数进行功能分解
functional decomposition with functions.

所以给他的一个题目也比较有意思
So I gave them an interesting practice problem.

但是对于初学者来说
However, it's a bit complicated

稍微有一点点复杂度
for beginners.

这个时候怎么去引导他在预习的过程中
So how do we help our students to understand

去体验这个功能分解呢
functional decomposition when they're preparing for class?

我给了一个预实践任务
I assign them a pre-practice task.

你也别写函数了
I ask them not to write functions,

你思考一下
but to think.

但是我函数还没有讲吗不是
I haven't taught them the functions yet.

你就写一个主函数
Then I ask them to write a main function

把判断一个数是否回文
to solve a small problem:

这一件小事解决一下
check if a number is palindromic.

其实这个是对前面第二章内容也是个复习
Actually, that's one way to review the previous chapter, Chapter 2.

然后上大课的时候我再给他演示
In the large class, I show them

你看我把功能分解成小的模块
how to split up functions into small sections.

是不是实现就更方便
Is it more convenient to implement the functions this way?

所以给了他这么一个预习的一个任务
So I assign this preview task to my students.

当然了第三章的预习有好多个预习任务
There're many preview tasks for Chapter 3.

我只是拿这一页来做一个样例
I've just taken this single task as an example.

其他预习任务还有的
There are other preview tasks too.

这是其中之一
This is one of them.

那么复习就是要配合大课
The review part means case-driven teaching based on a large class,

我是用案例驱动的这种教学
which is a teaching approach I use.

这个时候希望学生在复习中
For the review part, I hope my students

对例题从不同的角度进行修改和思考
will modify the practice problems and think about them,

进行归纳和总结
and design summaries and conclusions from different perspectives.

那么这是复习的要点
That's the key point for a review.

也是给大家看一个简单的复习的样例
I'd like to give you a simple example of a review.

比如说我在这个例子中讲了关于构造函数
For instance, I talk about constructors in this example.

上课因为学时有限
Due to the limited time in class,

我不可能所有的函数都单步追踪进去
I can't analyze all of the functions, bit by bit,

一点点分析
using single-step tracing.

那么把这个任务就留给复习
So I leave that task for the review part.

而且这样做学生对这部分内容的印象
In addition, the students will be more impressed

自己去单步跟踪的
by this content since they get to

对这部分内容印象会比较深
complete the single-step tracing themselves.

所以给他一个复习任务
So I give them a review assignment

请单步跟踪运行过程
for carrying out single-step tracing for the running process,

理解构造函数被调用的时机等等
understanding when to use constructors, and so on.

并且让他设计不同的重载形式的构造函数
I also let them design constructors with different overloading forms.

这又是一个延伸
That's another extension.

那么这个复习任务
This review task

不是简单的看看复习课件就可以的
can't be completed just by reading the review courseware.

雨课件只是给他一个指导
The Rain [Classroom
]Classroom courseware only gives them some instructions.

那么他要完成这个复习任务
To accomplish this review task,

需要相应的实验环境的
they need a responding experiment environment.

接下来再看看
Now let's take a look at

我给学生推送的部分自学内容
part of the content for self-teaching that I send to my students.

这个就是要推送慕课视频给学生了
I need to send MOOC videos to my students.

比如说在讲第一章绪论的时候
For example, when teaching the first chapter, Introduction,

我会把1.4节信息的表示与重组
I ask my to students to learn Chapter 1.4, Representation and Restructuring of Information,

留给学生自学
by themselves.

这个时候在我设计的这个雨课件里面
At the time, in the Rain [Classroom
]Classroom courseware

自学雨课件里面
I designed,

这个视频的内容它只是一个占位符
this video's content only acted as a placeholder.

看着是黑窗口
It's just a black window.

但是发到学生手机上的学生看到的
But the version sent to the students' cellphones

就是慕课里面的我的讲课视频
is a video of my lecturing in an MOOC.

这样的话
In this way,

学生如果说能看看书就能理解
it's great if the students can understand the content

非常好
just by reading books.

如果看书理解不了
If they don't understand it by reading books,

讲课视频推送到手机上了
with the lecture video sent to their cellphones,

他学起来就比较方便
it can be easier for them to learn it.

还有呢在面授课堂中
Moreover, during the face-to-face class,

我会安排一些随堂练习
I would set up some class exercises,

这个随堂练习包括复习题 预习题
including review exercises, preview exercises

和当堂讲课内容的练习题这样三类
and exercises for this class.

那么也是一个简单的例子
Here's a simple example as well.

我们这儿呢看到了
Here we can see

学生在手机上看到的
that the first one on the left that the students see

左边第一个这是个复习题
on their cellphones is a review exercise.

是对以前内容的一个复习
It's a review of the previous content.

也有关于新内容的预习题
Here's a preview exercise for the new content as well.

还有讲课的时候当时的练习题
Here's an exercise for this class too.

那么这些题目学生做完了以后
After students have finished solving these problems,

老师的教师端都可以看到
teachers can find out on the teacher's terminal

他每个ABCD选项的人数
the number of students that choose A, B, C or D.

你可以看到多少人做对了
You can find out how many students got the correct solutions.

百分之多少人做错了
You can find out the percentage of the students who choose the wrong answer

错在什么地方
and the mistakes they made.

那这个时候
At this point,

你就知道学生学习中的问题了
you get to know the problems that students encounter during learning.

于是你可以根据这个问题
So, based on that, you can give

进行适当地解释复习巩固
appropriate explanations and help students review and reinforce what they've learned.

然后继续前行
Then you can move on.

这样的话
In this way,

你就可以带动全班跟你一起走
you're able to motivate the whole class to moving forward[Moving forward
] you,

而不会像一个导游
instead of moving ahead blindly,

盲目地举着旗子往前走
like a tour guide holding a flag

什么时候你一回头
who turns around to find

后面队伍都跟不上了
that the rest of their group has fallen far behind.

不会出现这样的情况
That won't happen.

这个
That is

我认为是课堂练习非常有用的一个作用
one of the most important uses of class exercises, I think.
