Highlighting: (in the context of REAP) altering visual characteristics of a target vocabulary word--such as color, font-weight, and underlining--in a way that makes that word more visually salient in order to draw the learner's focus attention to that word.
Does highlighting target vocabulary words in practice readings improve second language vocabulary acquisition in a vocabulary tutoring system?
Does highlighting of target vocabulary words have any additional effects on reading behaviors? For example, do students spend less time reading a text when words are highlighted because they ignore anything that isn't highlighted?

Evidence of Transfer: sentence production tasks for target words.
Highlight of target vocabulary words in practice readings. In the control condition, students see a practice reading as is from the original source (the web). In the experimental condition, students see practice readings with target words highlighted in blue and underlined--that is, as hyperlinks commonly appear. Students in both groups have access to dictionary definitions for all words, and after each reading work through vocabulary practice exercises for target words.
Highlighting will improve acquisition of target vocabulary words.
