The Word Mapping Strategy helps older students learn how to predict the meaning of unknown words. Students learn to identify prefixes, suffixes, and roots and practice predicting the meaning of words using those parts. They also learn to use four strategic steps to identify the parts of a word, determine the meaning of those parts, and predict the meaning of the word.
In a study involving 230 high school students enrolled in general education English classes, students were randomly assigned to receive instruction in the Word Mapping Strategy, to receive instruction in the LINCS Vocabulary Strategy, or to receive traditional vocabulary instruction. The study showed that students who have been taught the Word Mapping Strategy can learn the meaning of vocabulary words when they use the strategy and can predict the meaning of significantly more words than students who use another similarly powerful vocabulary strategy. When researchers measured the students' ability to predict the meaning of unknown words, results showed significant differences between the posttest scores of students with disabilities in the Word Mapping group and those in the LINCS group or the traditional instruction group. Significant differences also were found between students without disabilities in the Word Mapping group and those in the LINCS group or the traditional instruction group. Word Mapping students earned an average of 61 percent of the points available on the prediction test compared to an average score of 24 percent earned by LINCS students.
