Other features demonstrated in Figure 6 include the ‘Look Up’ feature that lets the user filter the accordion-style listing of the words in the current chapter. If the user wants to practice the vocabulary in this chapter, he clicks the ‘Practice’ button, and the system will switch to a flashcard like interface (Figure 7). The user can mark a card as correct or wrong to indicate whether he has mastered the sentence. Additional options are ‘Previous’, ‘Show Answer’, ‘More Like This’, and ‘Next’. The ‘Previous’ option lets a user backtrack to the previous word that he practiced.
