### SCIENTIFIC METHOD (2).pdf

1. 1. ARCHA S R SCIENTIFIC METHOD
2. 2. ❑ METHOD WHICH IS USED TO SOLVE PROBLEMS SCIENTIFICALLY. ❑“METHOD OF SCIENCE” OR “METHOD OF SCIENTIST” ❑DELIBERATE EFFORTS ARE NEEDED TO FACILITATE ❑MORE EFFECTIVE THAN TRADITIONAL TEACHING METHODS WHAT IS SCIENTIFIC METHOD?
3. 3. ❑ PROCESS OF FINDING OUT RESULTS BY ATTACKING A PROBLEM IN DEFINITE STEPS. ❑ INVOLVES CRITICAL THINKING,LOGICAL REASONING,SYSTEMATIC ORGANISATION AND UNDERSTANDING AT EACH STEPS. ❑STUDENTS ARE INVOLVED IN INVESTIGATORY PROBLEMS WHOSE SOLUTIONS ARE NOT AVAILABLE IN BOOKS.
4. 4. STEPS OF SCIENTIFIC METHOD ◦THERE ARE 6 STEPS IN SCIENTIFIC METHOD; 1. QUESTION 2. RESEARCH 3. HYPOTHESIS 4. EXPERIMENT 5. DATA ANALYSIS 6. CONCLUSION
5. 5. 1. QUESTION OR PURPOSE ❑IT STARTS WHEN YOU ASK A QUESTION ABOUT SOMETHING THAT YOU OBSERVE
6. 6. RESEARCH
7. 7. 2. RESEARCH ❑CONDUCTING BACKGROUND RESEARCH ON THE QUESTION ❑LEARNER CAN USE; 1. LIBRARY 2.INTERNET 3.CHECKING REFERENCES 4.VIEWING ABSTRACTS 5.INTERVIEWING EXPERTS ❑THE MORE WE KNOW ABOUT THE SUBJECT, THE EASIER IT WILL BE TO CONDUCT INVESTIGATION
8. 8. 3.HYPOTHESIS ◦ THE ‘INTELLIGENT’ OR ‘EDUCATED’ GUESS. ◦ WRITTEN IN TERMS OF CAUSE AND EFFECT ◦ DESCRIBING RELATIONSHIP BETWEEN TWO PHENOMENA ◦ REJECTING A HYPOTHESIS IS MORE USEFUL THAN ACCEPTING ONE. ◦ MUST BE EASY TO MEASURE
9. 9. 4.EXPERIMENT ◦ TO TEST HYPOTHESIS ◦ SHOULD BE A FAIR TEST ◦ CHANGING ONE FACTOR AT A TIME ◦ SHOULD REPEAT THE EXPERIMENT TO MAKE SURE THE RESULTS WEREN’T JUST AN ACCIDENT
10. 10. 5.DATA ANALYSIS ◦ DATA COLLECTION AND ANALYSIS IS TO DETERMINE WHETHER THE HYPOTHESIS SUPPORT OR NOT ◦ IF IT IS NOT, ONE SHOULD GO BACK TO THE THIRD STAGE AND CONSTRUCT A NEW HYPOTHESIS BASE ON THE RESULTS OF 4TH STAGE. ◦ PROCESS OF SCIENTIFIC METHOD BEGINS AGAIN. ◦ IF IT SUPPORTS, TEST IT AGAIN IN A NEW WAY.
11. 11. ◦ RIGHT/WRONG; EITHER RESULT IS FINE. ◦ TESTING HYPOTHESIS AGAIN AND AGAIN GIVE DIFFERENT RESULTS. ◦ COMMUNICATION OF RESULTS IS NECESSARY.
12. 12. COMMUNICATION
13. 13. ADVANTAGES ◦ DO THEIR OWN LEARNING UNDER THE GUIDANCE OF THEIR TEACHER ◦ TO PROPOSE,FORMULATE AND STRUCTURE PROBLEMS ◦ TO COLLECT VARIED INFORMATION FROM DIFFEERENT SOURCES. ◦ COLLECT EVIDENCE TO PROVE OR DISPROVE IDENTIFIED HYPOTHESIS ◦ MORE CLOSELY FAMILIAR WITH APPLICATIONS AND RELATIONSHIPS INSTEAD OF HAVING MERE KNOWLEDGE ◦ LEARN TO SOLVE EVERYDAY PROBLEMS
14. 14. DISADVANTAGES ◦ VERY SLOW, LONG, AND TIME CONSUMING ◦ TOO MUCH EMPHASIS ON PRACTICAL WORK ◦ TEACHERS HAVE NOT PRACTICED TEACHING IN THIS METHOD ◦ ALL STUDENTS ARE NOT CAPABLE
