TEACHING AND LEARNING ARE STUDENT CENTERED
ACTIVITIES.
SO WE NEED INNOVATIVE METHODS IN TEACHING
AN INNOVATIVE METHOD IS A METHOD THAT CREATES AN
INTEREST IN THE STUDENT
MODERN GADGETS ARE NOT ESSENTIAL. BUT THEY ARE
DESIRABLE.

IT IS ESSENTIAL THAT ANY NEW TECHNOLOGY IS
INCORPORATED AS AN EDUCATIONAL TOOL. ALL NEW
ELECTRONIC DEVICES ARE USED AS EDUCATIONAL
TOOLS. RADIO AND TELEVISION HAVE PROVED THEIR
CAPABILITY AS EDUCATIONAL MEDIA. NOW COMPUTERS
ARE BECOMING POWERFUL TOOLS FOR IMPARTING
KNOWLEDGE AND ALSO FOR EXAMINATION PURPOSES.

CHEMISTRYPHOBIA
THE WAY IN WHICH IT IS TRANSACTED NOT AWARE
OF THE POTENTIAL OF CHEMISTRY NOT EXPOSED TO
THE RECENT DEVELOPMENTS IN CHEMISTRY
AS CHEMISTRY TEACHERS WE SHOULD BE PROUD TO
ASSERT THE IMPORTANCE OF CHEMISTRY

IMPORTANCE OF CHEMISTRY
CHEMISTRY IS EVERYWHERE REVENUE OF A
COUNTRY DEPENDS ON CHEMICAL INDUSTRIES
HIGHEST KNOWLEDGE EXPLOSION ESPECIALLY IN
ORGANIC CHEMISTRY LARGE NUMBER OF JOB
OPPORTUNITIES

WHAT IS CHEMISTRY?
IT IS ABOUT MAKING MATTER THAT NEVER EXISTED
CHEMISTRY IS THE MOTHER SCIENCE
IT IS AS OLD AS THE UNIVERSE
7
ALL OUR BASIC NECESSITIES ARE MET BY
CHEMISTRY. CHEMISTRY HAS EXTRAORDINARY IMPACT ON
SOCIETY. CHEMISTRY IS THE CENTRAL, USEFUL AND
CREATIVE SCIENCE Ronald Breslow NEXT CENTURY IS
THE AGE OF MOLECULES

MATHEMATICS IS THE LANGUAGE OF SCIENCE PHYSICS IS
THE PHILOSOPHY OF SCIENCE CHEMISTRY IS THE REAL
LIFE OF SCIENCE

EVOLUTION OF CHEMISTRY
MODERN CHEMISTRY STARTED WITH LAVOISIER
(1743-1794) DALTONS ATOMIC THEORY 1803 ANOTHER
STAGE STARTED WITH RUTHERFORD G N LEWIS STARTED
THINKING ABOUT BONDS LINUS PAULING REVOLUTIONISED
CHEMISTRY FARADAY (1791-1867) WAS BASICALLY A
CHEMIST. He discovered benzene, CCl4. He was
the first one to prepare Nanoparticles.

EVOLUTION OF ORGANIC CHEMISTRY
WOHLERS SYNTHESIS OF UREA (1828) M.CHEVREUL
(1816) Preparation of Soap KEKULE
Quadrivalence of carbon Chain
and Ring Structure of
Benzene OUT OF THE FIRST FIVE NOBEL PRIZES, THREE
WENT TO KEKULES STUDENTS vant Hoff (1901)

COMPUTERS HAVE TWO MAJOR APPLICATIONS IN EDUCATION
COMPUTER MANAGED INSTRUCTION (CMI) COMPUTER
ASSISTED INSTRUCTION (CAI)

• IN CAI THERE ARE VARIOUS INSTRUCTIONAL MODES
• DRILL AND PRACTICE
• TUTORIAL MODE
• iii) SIMULATION MODE

14
ADVANTAGES OF USING COMPUTERS

• NOVELTY OF THE METHOD
• COLOUR, MUSIC AND ANIMATED GRAPHICS ADD TO
  REALISM
• PROGRAMMED LEARNING WILL HELP SLOW LEARNERS
• INDIVIDUALISED INSTRUCTION IS POSSIBLE
• STUDENTS CAN LEARN FROM GREAT TEACHERS
• vi) MINIMISE POLLUTION AND PRACTICALS CAN BE
  REPEATEDLY DONE.

15
WAYS OF USING COMPUTERS

• INTEGRATED - Computer program used along with
  teaching
• COMPLEMENTARY A part of the syllabus is covered
  with computers
• SUPPLEMENTARY - Additional resources
• iv) INDEPENDENT 100 instruction by computer
