【實用教育app】Vocabulary App|最夯免費app-綠色工廠好玩App

Vocabulary app uses a sophisticated algorithm (based on spaced repetition and Leitner system) to design adaptive multiple-choice vocabulary questions. It is built on a hypergraph of words constructed using lexical cohesion.Learning tasks are divided into small sets of multiple-choice tests designed to help you master basic words before moving on to advanced words. Words that you have the hardest time are selected more frequently. For a fixed word, the correct and wrong answers are selected adaptively giving rise to hundreds of combinations. After each wrong answer, you receive a detailed feedback with the meaning and usage of the underlying word.Works best when used every day. Take a test whenever you have free time.Designed and developed by Dr. Shiva Kintali, faculty member in the Department of Computer Science, Princeton University.
