Vocabu-Links was written as a tool for increasing student mastery of science concepts by improving their comprehension of key vocabulary. The main component of Vocabu-Links is the utilization of the flashcards, which the students create using the word list and 3x5 index cards. Several activities are suggested for reinforcing the words. A crossword puzzle and game board are included, as well as a test for assessing comprehension of the words. I teach in a low-income school and the majority of my students are labeled "at-risk." Since I began incorporating this vocabulary program, I have consistently had more than 90% of my students pass the science TAKS test, and the majority of them have received commended scores. I have created Vocabu-Links units for Physical, Earth, and Life sciences.
