About Learning - 学習関連

Q5.  Why is the number of words I can study different from the total number of words in the course?
A5.  Based on your V-Check Test, WordEngine removes vocabulary that you already know so you can concentrate on studying the most frequently occurring vocabulary words that you do not know.

Q6.  I study, but the number of words does not increase.
A6.  You studied words and phrases that are repeating to deepen your memory.  It is only when you study unseen words and phrases that the number of words known increases.

Q7.  What is Coverage? 
A7.  The term 'coverage' describes how many vocabulary words are known. Simply stated, coverage is a way of measuring your comprehension of the vocabulary appearing in written text and spoken dialog. Let's say there is an article with 100 different words. If you know all 100 words, then you have 100 percent coverage. If you know only 90 of the 100 words, then you have 90 percent coverage.

Q8.  How much coverage is needed for comprehension?
A8.  Latest research indicates that 97 percent coverage is an important threshold for comprehension of standard tests, books, web sites, newspapers, and magazines. The higher above 97 percent you are, the better your comprehension will be. If your V-Check score is below 97 percent, please make every effort to get to 97 percent as quickly as possible.

Q9.  How does V-Check calculate my coverage percentage?
A9.  There are over 300,000 words in the English language, but certain words tend to occur much more often than others. The word 'the' is the most frequently occurring word in written English, followed by 'of', 'and', and 'to.' The most frequent word 'the' represents about 7 percent of all the English words. This means if there is an article with 100 words, the word 'the' will usually occur about 7 times. Amazingly just the 1000 most frequent words represent about 75 percent of all the English words ever used and can provide you with 75 percent coverage of all English.

The V-Check test quickly identifies which specific English words you know. V-Check calculates coverage by comparing information about the words you already know and information about how frequently your known words tend to occur in the subject matter you are testing for.
英語には30万語以上の単語がありますが、その中にはよく使用される単語とそうでない単語があります。最も使用頻度の高い単語は、theです。そして of, and, to…, と続きます。最も使用頻度の高いtheだけで、全体の約7%を占めます。つまり、もし100語から成る文章があるとすると、そのうちの7語はtheということです。驚くべきことに、使用頻度の高い上位1000語で、全体の75%程度を占めます。もしあなたがtheという単語を知っていれば、少なくとも7% のカバレッジがあることになります。もし上位1000語を知っていれば、少なくとも75%のカバレッジがあることになります。


Q10.  What is Spaced Repetition?

A10.  Spaced repetition is the fastest way to permanently memorize new words. After you study a word it must wait a certain number of days before you can study it again. The waiting process increases the strength of your memory retention. Spaced repetition was first patented by Dr. Hermann Ebbinghaus in 1895. WordEngine combines Dr. Ebbinghaus’ original spaced repetition concept with our own patented process for providing you with only the most important words you need to improve your comprehension fast.
