I. PENDAHULUAN

I.1 A Taxonomy of the Cognitif DomainTujuan domain ranah kognitif berhubungan dengan tampilan kemampuan pengetahuan dan pengembangan kemampuan serta pengembangan keterampilan intelektual ( Bloom 1956:7). Taksonomi atau penggolongan tujuan ranah kognitif hasil pengembangan Bloom dan kawan-kawan mengemukakan adanya enam kelas / tingkat dari tingkatan yang terendah menuju tingkatan yang tertinggi, yaitu :

C1.Pengetahuan ( knowledge )C2.Pengertian, faham, pemahaman ( comprehension )C3.Pemakaian ( application )C4.Analisa , uraian, kupasan, pemeriksaan ( analysis )C5.Perpaduan, pembentukan ( systhesis )C6.Evaluasi, penilaian ( evaluation)
