Hello and welcome to viva physics! This
is a website that has been created for
students with the intention of
presenting physics in a more friendlier
way to the students. The content makes
liberal use of animations and
interaction, with the hope that this
improves student learning retention and
participation. Now this has been done for
the second part of physics that is
electrostatics,
electricity, magnetism, optics and modern
physics. The first part which includes
kinematics, dynamics, fluid mechanics, heat
and waves has not been covered and is
under development. So let's navigate
through this website and see what it
offers. We go to the lessons and we see
part 2 since part 1 hasn't been done as
yet. This takes you to a screen where you
see some topics listed on your left and
lessons related to that topic on your
right.
By default it shows you the lessons
related to Coulomb's law. All the topics
listed on the left side that is
Coulomb's Law, Electric Fields, Gauss's
Law, Electric Potential and Capacitors
they all fall under the broad category
of electrostatics. If you want to check
out what's under the other categories
you can click on the categories menu on
the top right hand side and it will list
out the different categories ranging
from electrostatics to modern physics.
Let's take for example electromagnetic
induction.
You can see that the chapter listing on
the left side has changed now. Let's
choose the chapter electromagnetic
induction and we see all the lessons
listed under this chapter. Let's select
lesson number five. We click on that
lesson and the lesson opens up and this
topic is the magnetic flux. The lesson
begins to play with some audio narration.
Now this lesson is divided into a series
of steps with each step on an average
running for about 40 seconds. After this
step is done you can click on the next
step button at the bottom which will
take you to the next step. The lessons on
an average contain four to five steps. If
you click on next again it will take you
to the third step and you can see some
animation here. Now if you haven't
understood a step you could always
repeat a step or you could go back to
the previous step. When you reach
the last step then in the navigator the
next step button would automatically
disappear so you would know that you are
on the final step in the current lesson.
This lesson consisted of four steps.
aAter you are done with the lesson you
could click on the practice button to
open up an interactive session at the
bottom. It gives you a parameter which in
this case is the angle between the area
vector a and the magnetic field B.
As you increase the angle you can see
that the magnetic flux shown by the blue
arrows keeps reducing. So for the student
this is an interactive way of
understanding a concept and this
develops a better interest in the
subject since they can see the effect of
changing parameters in real time. Now not
all lessons have a practice session but
a substantial number of them do. Having
completed this lesson if you want to
move over to the next lesson you need
not go back to the previous screen and
choose the next lesson. You can use these
two orange colored buttons on the top
right-hand side to help navigate between
lessons in the current chapter. So let's
click on the next lesson button. So now
we move over to the next lesson and you
can see that the contents of this lesson
have changed and we have now moved to
Faraday's law part one. Now you can use
the navigator again at the bottom to
step through this lesson. I will quickly
step through this lesson. The software
can really be used in two ways. The first
is for the teacher or educator by
turning off the volume and taking
advantage of the already drawn figures
and animations. The second is for the
students who can use it to learn at
their own pace at home or use it as pre
lecture material and in a way try out
the flipped classroom model so that the
lecture time in class can be more
meaningful and engaging. And for whatever
gaps are noticed in the understanding of
concepts, new lessons can be inserted or
existing
lessons can be modified with additional
steps. So this is really a continuous
improvement exercise. For the moment the
audio has been done in Indian English
but if you need to convert this to
another language or to a different
accent then all that has to be done is
that the audio files have to be created
in that language. Then the software will
offer you a choice of language but
importantly for language conversion, no
changes are required in the animation or
the software since each animation runs
in small snippets of less than 40
seconds. So you don't have to worry about
synchronizing the audio with the
animations. Well that's all! Hope you can
find time to use it comment on it and
send me the feedback. Thanks for your
time and thanks again for watching.
