3. Computer simulation is the use of a computer to represent the
dynamic responses of one system by the behaviour of another
system modeled after it.
A simulation uses a mathematical description, or model, of a
real system in the form of a computer program.
This model is composed of equations that duplicate the
functional relationships within the real system.
When the program is run, the resulting mathematical dynamics
form an analog of the behaviour of the real system, with the
results presented in the form of data.
4. A simulation can also take the form of a computer-graphics
image that represents dynamic processes in an animated sequence.
Computer simulations have become a useful part of
mathematical modeling of many natural systems in physics,
astrophysics, chemistry, biology, climatology, psychology, social
science, etc
5. USES
Computer simulations are used to study the dynamic behaviour
of objects or systems in response to conditions that cannot be
easily or safely applied in real life.
Simulations are especially useful in enabling observers to
measure and predict how the functioning of an entire system
may be affected by altering individual components within that
system.
Simulations have great military applications also.
Many uses for a computer simulation can be found within
various scientific fields of study such as meteorology, physical
sciences,etc .
7. The term ‘blended learning’ is generally applied to the practice of
using both online and in-person learning experiences when teaching
students.
In a blended- learning course, students might attend a class taught
by a teacher in a traditional classroom setting, while also
independently completing online components of the course outside
of the classroom.
In this case, online and in-person learning experiences are parallel
and complement to one another.
Blended learning has already produced an offshoot – the flipped
classroom-that has quickly beecome a distinct approach of its own.

10. MODELS
Blended learning can generally be classified into 6
models. They are:-
1)Face- to –face driver : where the teacher drives the instruction
and augments with digital tools.
2)Rotation: students cycle through a schedule of independent
online study and face-to-face classroom time.
3)Flex : Most of the curriculum is delivered via a digital platform
and teachers are available for face- to-face consultation and
support.
4)Labs : All of the curriculum is delivered via a digital platform but
in a consistent physical location. Students usually take traditional
classes in this model as well.
11. 5) Self-blend : Students choose to augment their traditional
learning with online course work.
6) Online driver : students complete an entire course through an
online platform with possible teacher check-ins. All curriculum
and teaching is delivered via a digital platform and face-to-face
meetings are scheduled or made available if necessary.
12. ADVANTAGES
Blended learning is more effective than purely face-to-face or
purely online classes.
Students can work on their own with new concepts.
Support individual students who may need individualized
attention.
Teachers can streamline their instructions to help all students
reach their full potential.
The use of information and communication technologies have
been found to improve student attitudes towards learning.
It reduce educational expenses.
Student logins and work times are also measured to ensure
accountability.
Students with special talents or interests outside of the
available curricula, use educational technology to advance
their skills.
It is one of the most effective ways for personalized learning.
13. Disadvantages
Blended learning has a strong dependence on the technical
resources or tools. These tools need to be reliable, easy to
use and up to date.
Use of lecture recording technologies can result in students
falling behind on the materials
Effective feedback is more time-consuming when
electronic media are used.
Many students do not have pervasive and ubiquitous access
to the internet.
15. For education, educational podcasts provides another way of
sharing and publishing both audio and video for teaching and
learning in schools, colleges and at home.
The technology infrastructure for creating and distributing
podcasts is evolving rapidly.
As well as just audio-only podcasts, there are currently two
other forms of podcast available- enhanced podcasts and video
podcasts.

17. Audio podcasts: As well as providing broadcast audio
for public access, children and young people are able to
record, produce and publish on the Internet podcasts of their
very own using basic software.
Enhanced podcasts: Enhanced podcasts may include
chapter marks, images that change at predetermined times
when the podcast is played and hyperlinks to websites.
Video podcasts: Vodcasts are the very latest in
podcasting and provide a full visual and audio experience for
the user.
18. EDUCATIONAL USES OF PODCASTS
1)Ease of accessibility: Podcasts enable students to access
the information any time they want. Students can download
the information to the device of their choice and listen or
watch whenever they are free.
2)Archive of lessons: Staff can record their classes and
upload it online, creating an archive of lessons. This allows
students to access previous lectures for reference and
clarification on a subject or to stimulate learning of the same.
3)Updates: Students subscribing to a particular podcast will
be notified if there is an update. A major advantage of
podcasting is that student who have subscribed will be sent
information constantly.
19. 4) Learning on the go: With podcasting, learning is no longer a
sedentary activity. As every lesson can be downloaded on
their iPod or MP3 player, students can attend to it even
when they are away from their study table.
5) Creative learning: Podcasting gives way to new strategies
like guest lectures, interviews, video demonstrations, etc. It
encourages students to develop their own podcasts, improve
their listening skills and enhances learning by targeting each
child’s interest.
20. Problems of podcasting
If not monitored, podcasting can be misused by its users.
Students may not pay attention in class to a lecture as they feel
the material is already available elsewhere.
They may also try to prepare for an exam based on the podcasted
material alone.
