Page 2 - FREQUENCY #1 VOCABULARY

preface |

Why does frequency matter on the iBT?

“Wow, the reading is no joke!” This has been a common reaction among iBT TOEFL test takers since
it first began in Sept 2005 (Sept. 1st 2006 in Korea). The length of the reading passages has more
than doubled from 280-350 words on the CBT to an average of 700 words on the new iBT. The longer
length of the passages has made them more difficult to grasp. Test takers who are unused to reading
about science often find the new iBT reading passages especially difficult.
The number of vocabulary questions given on the TOEFL has also increased drastically, and
these questions now constitute approximately one third of all the questions on the reading section. A
typical passage contains 4 vocabulary questions out of 13-14 questions total. Considering that the
reading section contains 3 or 5 reading passages, test takers will have to answer 12-20 vocabulary
questions on the new iBT. That’s really no joke.
In scrutinizing all the real iBTs given thus far, LinguaForum Research Center has found
something very interesting. Similar topics and questions have appeared repeatedly on the real tests.
In other words, the passages and questions the test takers witnessed on the today’s test will possibly
appear again on the next week’s test, next month’s test, or on a test some months later. That
repetition caused us to analyze the frequencies at which words have appeared on the real tests.
Using this analysis we have produced an innovative and ambitious book, Frequency #1 Vocabulary.
Setting priorities for iBT vocabulary building!
Frequency #1 Vocabulary has completed the LinguaForum iBT Vocabulary Series; Basic,
Intro, and Frequency. The 2,000 words in this book are the ones that have most frequently appeared
on the real test. We divide the words into two parts: top and second frequency, each part containing
1,000 words. Each section is then further subdivided into 20 chapters of 50 words each according to
the frequency in which they appear on the test. Thus, students first learn the words they are most
likely to see on the iBT and learn words that appear less frequently in later chapters. By prioritizing
vocabulary for the students, LinguaForum makes vocabulary building more streamlined and efficient,
increasing the potential of test takers worldwide.
