NGSL Builder Multilingual:

In English Japanese and Thai

This application is designed to help learners and teachers make use of one of the most important lists of vocabulary words for second language learners of English, the New General Service List (NGSL). The NGSL is a free open source wordlist and is used with permission.

The app contains simple tools to help you download, email and organize the NGSL, as well as science-based study tools to quickly and efficiently learn the words, keep detailed record of your progress and the ability to email your progress to yourself or a teacher.

The original definitions are written in simple English and the app also give you pronunciation of each word by a professional voice talent who is a native speaker of English of North American English.

About the NGSL:

The New General Service List (usually referred to as the NGSL) was published by Dr. Charles Browne, Dr.Brent Culligan and Joseph Phillips in 2013 after several years of of detailed corpus work with the well-regarded 2 billion word Cambridge English Corpus (CEC). The list is used with permission.

About Intelligent Flashcards:

The app also contains an Intelligent Wordlist Maker and Intelligent Flashcard system.

The Intelligent Wordlist Maker helps you to quickly and efficiently pick only the words you don’t know for study in the flashcard system. Rather than force you to go through the entire list at once, Intelligent Wordlist Maker guides you through the list by frequency bands, allowing you to add words little by little, just as you need them or when you have time.

Based on the well documented science of “spaced-repetition”, the Intelligent Flashcard system systematically and efficiently helps you to review the words several times over a period of a month, giving you extra time with the words that are giving you difficulty.
