5 Classroom Researchis the process of systematic investigations to answer questions or solve problems about teaching and learning involving a specific group of students in a particular setting for the purpose of improving instruction
12 Research designs One group pre-test and posttest A1 T A2 A1 = pretest T = treatmentA2 = posttest
13 Research design 2. Two groups posttest only T A - B A = group A T = treatmentB = group B
14 Research design Two group pre-test and posttest A1 T A2 B1 - B2 A = group A (1-pretest, 2-posttest)T = treatmentB = group B (1-pretest, 2-posttest)
15 Research design 4. One Group Time Series A1 A2 A3 T A4 A5 A6 A1 A2 A3 = pretest in different timeT = treatmentA4 A5 A6 = posttest in different time
16 Research design 5. Two Group Time Series A1 A2 A3 T A4 A5 A6 B1 B2 B B4 B5 B6A1 A2 A3 = pretest in different timeT = treatmentA4 A5 A6 = posttest in different time
17 Research design 6. Trend design A T B T C T D T E A B C D E = each group but in the same class in different timeT = treatment
18 Research design 7. Reversal Design suitable for behavior modification of difficult studentA T T T T A2A = studentT = treatment- = no treatment
19 Research design 8. Survey Design Use to measure students’ attitude, belief or perception
20 Data collection toolsObservationQuestionnairesInterviewTest
21 Analysis of data Qualitative analysis; idea, words Quantitative analysis; graph ,statistic T test, chi square
22 Draw conclusion Is there any change after intervention? How does it works?If it does not work , why?What is the new plan?
