5 Metode Penelitian 1.Action Research • The carefully documented and monitored study of an attempt by researcher, to actively solve a problem and change a situation (Herbert, 1990) 2.Experiment • An investigation of causal relationships using tests controlled by researcher • Performed in development, evaluation and problem-solving project 3.Case Study • An in-depth exploration of one situation (Cornford and Smithson, 2006) 4.Survey • The collection of a large amount of data from a sizable population in a highly economical way (Saunders et al., 2007) • Undertaken through the use of questionnaires or interviews (Dawson, 2009) 5

6 Desain Penelitian Eksperimen 1.Pre-Experimental Design 1.One-Shot Case Study 2.One Group Pretest-Posttest Design 3.Intact-Group Comparison 2.True-Experimental Design 1.Posttest Only Control Design 2.Pretest-Control Group Design 3.Factorial Experimental Design 4.Quasi Experimental Design 1.Time-Series Design 2.Nonequivalent Control Group Design 6

7 Pre-Experimental Design • Tidak ada variable kontrol dan data tidak dipilih secara random • Belum disebut eksperimen yang sebenarnya, karena kemungkinan ada variabel eksternal yang mempengaruhi terbentuknya variable dependen • Bentuk pre-experimental design: 1.One-Shot Case Study 2.One Group Pretest-Posttest Design 3.Intact-Group Comparison 7

8 One-Shot Case Study X = perlakuan yang diberikan (variabel independen) O = hasil (variabel dependen) X O 8

9 One Group Pretest-Posttest Design O 1 = Pretest X = perlakuan yang diberikan O 2 = Posttest O 1 X O 2 9

10 Intact-Group Comparison X = perlakuan yang diberikan O 1 = hasil pengukuran setengah kelompok yang diberi perlakuan O 2 = hasil pengukuran setengah kelompok yang tidak diberi perlakuan X O 1 O 2 O 2 10

11 True-Experimental Design • Kelompok kontrol dan sample diambil secara random dari populasi • Peneliti dapat mengontrol semua variabel eksternal, sehingga validitas internal tinggi • Bentuk true-experimental design: 1.Posttest Only Control Design 2.Pretest-Control Group Design 11

12 Posttest Only Control Design R = Random (Acak) X = perlakuan yang diberikan O 1 = hasil setelah perlakuan O 2 = hasil tanpa perlakuan R X O 1 R O 2 12

13 Pretest-Control Group Design R = random (acak) O 1 = pretest X = perlakuan yang diberikan O 2 = posttest setelah perlakuan O 3 = pretest O 2 = posttest tanpa perlakuan R O 1 X O 2 R O 3 O 4 13

14 Factorial Experimental Design • Perbaikan dari true-experimental design dengan memperhatikan kemungkinan adanya variabel moderator yang mempengaruhi perlakuan • Seluruh kelompok dipilih secara random dan masing-masing dilakukan pretest • Kelompok penelitian dinyatakan baik apabila setiap kelompok memiliki nilai pretest yang sama 14

15 Factorial Experimental Design Y = variabel moderator R O 1 X Y 1 O 2 R O 3 Y 1 O 4 R O 5 X Y 2 O 6 R O 7 Y 2 O 8 15

16 Quasi Experimental Design • Digunakan ketika kita sulit mendapatkan kelompok kontrol seperti pada true- experimental design • Lebih baik daripada pre-experimental, meskipun tidak sebaik true-experimental • Bentuk quasi experimental design: 1.Time-Series Design 2.Nonequivalent Control Group Design 16

17 Time-Series Design O 1 = Pretest X = perlakuan yang diberikan O 2 = Posttest O 1 O 2 O 3 O 4 X O 5 O 6 O 7 O 8 17

18 Nonequivalent Control Group Design • Hampir sama dengan pretest-posttest control group design, hanya pada desain ini kelompok tidak dipilih secara random O 1 = pretest X = perlakuan yang diberikan O 2 = posttest setelah perlakuan O 3 = pretest O 2 = posttest tanpa perlakuan O 1 X O 2 O 3 O 4 18
