Skilled reading is complex cognitive process that entails the simultaneous and increasingly strategic use of language comprehension and automatic word recognition. In English, specifically, there are any sub-skills are involved in this process including an awareness of the morphological structure of language. Morphological awareness, or the ability to understand how words are broken in to meaningful units (e.g., affixes, root words), is important for readers in upper elementary, middle and secondary grades. In order to teach morphological concepts and their relation to reading, teachers themselves need to have an understanding of morphological concepts. The present study examined general and special education teachers' knowledge of morphological concepts. Results indicated that teachers, regardless of type of certification (GEN vs. SPED) or grade level (elementary vs. secondary) had difficulty identifying morphemes in both simple and complex words.
