Pengembangan instrumen penilaian afektif siswa kelas IV sekolah dasar di Kabupaten Klaten

Penelitian ini bertujuan untuk menghasilkan instrumen yang memenuhi syarat untuk mengukur afektif siswa kelas IV, dan mengetahui gambaran afektif siswa kelas IV tahun ajaran 2016/2017 di Kabupaten Klaten. Pendekatan yang digunakan dalam penelitian ini adalah Research and Developmentdengan Model Thiagarajan. Instrumen penilaian afektif telah dinyatakan valid dan reliabel. Validitas isi diuji oleh ahli dan diperoleh indeks Aiken sebesar 0,85. Validitas konstruk dilakukan dengan analisis faktor eksploratori dan konfirmatori. Hasil analisis faktor eksploratori menunjukkan nilai KMO sebesar 0,726 sedangkan Bartlett’s Test sebesar Sig. 0,000. Hasil analisis faktor konfirmatori menunjukkan nilai Chi-Kuadrat sebesar 0,039; RMSEA= 0,012; GFI=0,93; SRMR=0,033; AGFI=0,90; CFI=1,00; RFI=1,00. Hasil reliabilitas menunjukkan bahwa koefisien Cronbach’s Alpha sebesar 0,653 sedangkan pada reliabilitas konstruk menunjukkan bahwa pada sikap disiplin koefisien CR=0,99 dan VE=0,99; sikap jujur CR=0,99 dan VE=0,99; sikap peduli CR=0,99 dan VE=0,99; sikap percaya diri CR=0,94 dan VE=0,95; sikap santun CR=0,99 dan VE=0,81; sikap tanggung jawab CR=0,99 dan VE=0,79. Gambaran afektif siswa adalah (a) berdasarkan tingkatan afektif Krathwohl, Bloom & Masia pada tingkatan karakterisasi sebesar 42,9%, mengorganisasi sebesar 50,9 %, menilai 6,2% sedangkan tahapan merepon dan menerima sebesar 0%, (b) berdasarkan acuan Kurikulum 2013 pada kategori baik sekali sebesar 62%, kategori baik 38% dan kategori cukup 1%, kategori butuh bimbingan sebesar 0%.Kata kunci: penilaian afektif, sikap, tingkatan afektif Krathwohl, Bloom & Masia, analisis faktor eksploratori, analisis faktor konfirmatori DEVELOPING AFFECTIVE ASSESMENT INSTRUMEN OF FOURTH GRADE STUDENT IN KLATEN REGENCYAbstractThis study aimed to:  produce qualified instrument to measure an affective of grade IV students and find out the affective picture of fourth grade students in academic year 2016/2017 Klaten. This study used Research and Development approach by using Thiagarajan Model. Affective assessment instruments were stated as valid and reliable. Content validity was judged by experts. The Aiken index of instruments is 0.85. Construct validity was measured by using both exploratory and confirmatory factor analysis. The results of exploratory factor analysis showed that the KMO value is 0.726 while the Bartlett’s Test is equal to Sig. 0,000. Confirmatory factor analysis showed that Chi-Square value is 0.039; RMSEA = 0.012; GFI = 0.93; SRMR = 0.033; AGFI = 0.90; CFI = 1.00; RFI = 1.00. Cronbach's Alpha coefficient is 0.653 while the construct reliability showed the coefficient of discipline CR = 0.99 and VE = 0.99; honest attitude CR = 0.99 and VE = 0.99; attitude caring about CR = 0.99 and VE = 0.99; self-confidence CR = 0.94 and VE = 0.95; polite attitude CR = 0.99 and VE = 0.81; the attitude of responsibility CR = 0.99 and VE = 0.79. The description of students’ affective was (a) based on the affective level of Krathwohl, Bloom & Masia,  level of characterization 42.9%, organizing 50.9%, assessing 6.2% while phoning and receiving 0%, (b) based on the 2013 Curriculum reference, it could be stated as excellent category 62%, favorable category 38% and fair category 1%, the category needs guidance at 0%.Keywords: affective assessment, attitude, Krathwohl affective level, Bloom & Masia, exploratory factor analysis, confirmatory factor analysis
