In
the first video "Let's use video to reinvent education", Salman Khan has introduced specifically about the
advantages of free teaching videos. To begin with, he narrated about his
experience with his cousins. After posting some videos on Youtube to tutor his
cousins, he received some comments that he did better on video than in real
life. Additionally, they don't feel that they are wasting the time of Salman
Khan because they can watch the videos again and again even when they need to
review the information that they was taught few years ago. That is the first
advantage of teaching video, it allows the learners to study with their own
pace at their own time. It is impossible in traditional classrooms, just like
the author of the article "The TransformationPotential of Flipped Classrooms" said, either the teacher wants or
not, she must keep the pace of the lecture for the whole class although it is
too slow for some students and too fast for the others. Everyone has different
schedule and ability to obtain information, so the one-for-all syllabus is
definitely not appropriate with the whole students in the class. Secondly, Khan
has also gotten large amount of comments on Youtube when he declared his videos.
They said that the videos bring the positive attitude for the learners. For
instance, someone said "First time I
smile doing derivative". From my own experience, math is boring, every
time, and only thing I can do when doing math is just focusing on the problem,
thinking how to solve it. However, Khan's video can bring the inspiration to
the learners, and it has great impact on studying process. The most impressive
example is the one about the boy that has autism. He had problem with math,
could not achieve the expected result although his parent tried everything.
Fortunately, the videos from Khan suddenly help that boy to get over that
problem. He made it. Honestly, the teaching video method has changed that one's
life. From that example, we can conclude the next advantage of this method, it
has great potential to change the education. Khan got some letters from
teachers and schools, they stated that those teaching videos can be applied
into the classroom because they recognized the potential of this method. It not
only help the children to learn on their own pace but also help teachers to
track the learning process of the students. The number and result from Los
Altos provided us the conclusion that the method is working really well. By
tracking students' learning process, the teacher is now able to know which
knowledge that students need to be improved, which information that they
already obtain completely. Then, from those data, the teacher can ask the
students who understand the concept clearly to tutor other students. From some
aspects, peer-to-peer tutoring is better than teacher-student communication.
They can use the easiest and familiar language to each other. However, the
learners still need the instruction from the teacher because only teacher
understands the concept completely and has deep, academic knowledge. In
traditional classroom, the teacher only use 5% of their time sitting next to
the students and work with them. But teaching videos created flipped classroom,
where teacher can spend their whole time on class with their students directly.
Come back to the article "The
Transformation Potential of Flipped Classrooms", the flipped classroom
will create time for students to engage directly to their learning process,
they are able to practice problems with guidance from teacher, discuss issues
with classmates, and work on specific projects. From my point of view, I would allow
my students to learn the concepts from Khan Academy at home. With the diverse
and huge database, covering almost all basic subjects, I believe the learners
can find any information from Khan Academy. I, the teacher, don't need to worry
about the financial problem because the supply from teaching videos is free. I
also don't have to "host"
the database because of the availability of cloud computing. All of the
information is stored on the cloud and the students is allowed to access at
anytime. In addition, I don't have to touch the hardware physically. Instead, I
can manage everything about the information and details through my personal
computer. "You can stop worrying
about your hardware, you can work on building your business instead. Using
cloud hosting will save your time, and money. And it's there for you to use
instantly" (Cloud Computing Explained video). After, the students in
my class can take some online quizzes to check their own learning process to
see if they obtain enough knowledge or not. Finally, when they attend the
flipped classroom at school, they are allowed to discuss the problem they had,
how they resolve it, share the ideas and collaborate to work on specific
projects. Although teaching videos and cloud computing are useful tools to
support education, there are still some weaknesses and disadvantages of those
technologies. I believe in next few years, these problems can be solved
gradually, it depends not only on the development of technology but also on the
way we utilize and apply them.
