An Attempt On

1
An Attempt On

• Learning Without Burden

2
Based on guiding principles (
NCF-2005) and that

• Good science education is
• true to child ,true to life and true to
  science,leading to basic criteria of validity
  of science curriculum,which are
• Cognitive validity
• Content validity
• Process validity
• Historical validity
• Environmental validity
• Ethical validity
• Thereby, helping the student in getting
  creative,inventive and learning to learn
  science.

Rational behind construction of exhibit

• Highly motivated by the recommendation of
  NCF-2005,that ,
• with active teacher participation ,the
  reform stated in (NCF-05) could have a
  cascading affect on all stages of science
  teaching in our school s and enrich joyful
  learning would take place through project
  works,information communication technology,
• it was deciding to work on projectile
  motion trying to cover the maximum
  recommendation of NCF-2005.

5
Rational behind construction of
exhibit

• It is an attempt to improve upon the
  quality of teaching and learning process.And
  also to make students aware about the
  projectile motion in daily life. It is also
  in attempt to popularize science and realize
  the relationship between science and the
  society.
• This aid will definitely stimulate
  scientific temper among students.

6
About the teaching aid

• This teaching aid includes teaching the topic
  in different way such as-
• Learning by doing . An activity based
  exhibit,based on constructive creative approach
  of learning ,to create enquiry mind.
• (as NCF says-
• Enquiry skill should be supported
  strengthened.
• Spread a wave of creativity and scientific
  temper among students as well as their
  teachers.)

7

• Play way- joyful learning -a flip book showing
  animated motion based on principal of persistence
  of vision.

8

• Environmental validity linkage -A magic box
  using a special technique of linkage , joining 8
  small cubes showing information on projectile
  motion examples from daily life.

9

• Learning using ICT -(information communication
  technology)
• It is a CD having power point presentation
  including animations,hyperlinks and video clips.
• (as NCF says-
• ICT is an important tool for budging social
  divides.ICT can become an opportunity equalizes
  by providing information,communications
  computing resources in remote areas.
• Rote learning should be discouraged.)

10

• Theatre in education-
• Here is an small attempt to dramatize text
  which is a small part of theatre.
• (as NCF says-
• Theatre is one of the most powerful,yet
  least utilized art form in educations . Not
  only for humans but also towards the natural
  physical worlds,theatre is a medium for
  excellence.)

11

• Interactive questionnaire (in C.D.)
• (as NCF says-
• Interactive,net enabled computers ,rather
  than only C.D based computer usage ,would
  facilitate a meaningful integration of computers
  enhance the school curriculum in rural
  remote areas by increasing connectivity
  enhancing access to ideas information's)

• CD in Hindi-
• (as NCF says-
• use of ICT is access to knowledge in
  regional language is still limited and is one of
  the main reasons for the persistence growing
  divide between learners from urban rural
  schools learners from regional language
  English medium schools.)

• Cognitive validity linkage-
• Exhibiting concept of horizontal vertical
  velocity vector.

14

• Useful web sites-
• To support and strengthen enquiry skills of the
  students

DescriptionConstruction and working of the
exhibit

• PROJECTILE MOTION , learning by doing

• Makes the child understand the dependence of
  horizontal range(h),maximum height (h) on
  velocity (v) and angle of projection(?) of
  the projectile.
• Changing the angle of slide and velocity
  of ball by velocity control elastic, we can
  understand the effect of v and ? on h and
  r.

• Play way-Joyful learning

Small flip book gives the moving visual
effect of body projected in air. It depends
on the concept of persistence of vision.
18
Environmental Validity linkage approach of
learning

• The information magic box,contains
  information about projectile motion,example from
  our daily life environment.

Information magic box contains information
about projectile motion, examples of daily
life etc in.8 small boxes of big box
attached technically so as to facilitate
exposure of all faces of small 8 boxes
i.e.8648 faces all open for information..

Learning by ICT

• Compact Disk contains the power point
  presentation of the topic with animated
  applications, hyper links of projectile motion
  and many more options to learn more on projectile
  motion.

21
Theater in Education
Theater is one of the most powerful , yet least
utilised at forms in education. In the
exploration of self in relation to others, the
development of understanding of the self, and of
critical empathy , not only for humans but also
towards he nature, physical and social worlds,
Here is an attempt to create interest and
understanding on the topic through theater .
22
Interactive Questionnaire

• Contains multiple choice questions on projectile
  motion which has been prepared in power point
  presentation.

23
ICT (for Hindi medium students)

• Small attempt to decrease the gap between
  rural and urban students.
• A Power point presentation in Hindi have been
  prepared to make possible the use of ICT by
  rural hindi medium school students.

Select for Hindi Presentation
24
Cognitive Validity Approach

• It clears the concept of horizontal and
  vertical component of velocity vector of
  projectile body.

• Interactive Class room

Hyperlinks address of sites can be provided to
students for the study beyond the book.

Learning without burden

• Play a game
• Blast a Buick out of a cannon!
• Learn about projectile motion by firing
  various objects. Set the angle, velocity and
  mass, adding air resistance also.

26
Application

• This teaching aid will be of high utility
  while teaching the topic-projectile motion
  in class.
• It objectives of NCF-2005 are being satisfied.
• Develops abilities necessary to do
  scientific inquiry and science innovations.
• Develops abilities necessary to communicate
  and defend scientific arguments .
• Rote learning by the student is discouraged.

27

• It satisfies---
• learning without burden,joyful
  fearing,constructive,creative,inventive approach
  of learning.
