Vocabulary teacher blogs5/6/2023 ![]() ![]() Once dissected, students are encouraged to discuss (and guess) the role/meaning of the morphemes. For example, using the word bio-chem-ist, students cut off, pronounce, and separate the three meaningful word parts, bio- (prefix), -ist (suffix), and -chem- (root/base). Working in pairs, students read the words aloud they discuss recognizable roots, affixes, and their positions in words and they dissect the word, by cutting the strips into constituent parts. ![]() ![]() In one dissection activity, students are provided with words written on strips of paper. Reason 2: Technical Science Words Have Unfamiliar Spelling Patternsĭissection, a specific word analysis strategy, involves separating and isolating prefixes, roots, and suffixes in novel multimorphemic words. A morphological approach helps students to decode and supports recognition of familiar spelling patterns that preserve meanings of multimorphemic science words ( Carlisle & Stone, 2005). This parsing not only supports decoding but knowing something about dendro- (tree), - chrono- (time), and -logy (the study of) also gives clues to the meaning of the word dendrochronology (i.e., the study of the annual rings of trees in determining the dates of past events). Alternatively, students could use a morphological approach to parse the word into meaning-based, pronounceable chunks (i.e., dendro-chrono-logy). Syllables, however, do little to help students access spelling patterns or the meaning of a word. Students could read the word using a syllable approach (i.e., den-dro-chro-nol-o-gy), which supports decoding for struggling adolescent readers ( Bhattacharya & Ehri, 2004). For instance, dendrochronology has six syllables, 16 letters, and three morphemes. ![]() Many technical science words, sometimes called “big words,” generally consist of two or more syllables, eight or more letters, and in many cases, multiple morphemes ( Cunningham, 1998).
