Lance reading grading standard
Semantic difficulty, that is, word frequency.
Lance analyzed more than 50 forms of semantic changes, and identified the causes of text reading difficulties. The results show that the most important factor is word frequency, which has the highest correlation coefficient with text reading difficulty. The frequency of words mentioned here is not the number of times a word appears in a specific paragraph, but the frequency of the word appearing in nearly 6 billion words of materials analyzed by Lexile.
Syntactic complexity, that is, sentence length.
The researchers found that long sentences contain more clauses, which not only contain more information and concepts, but also are related to each other. In addition, longer sentences require students to hold more information in short-term memory, which makes them more difficult.
Structure indicator (structure indicator)
By calculating the degree of text repetition, the overall difficulty of the text is evaluated.
Lexical indicator (decoding indicator)
By counting vowels, consonants and pronunciations in words, the difficulty of using words is evaluated.
Letter symbols in Lan Se's values
The blue values of books we have inquired about often have some letter symbols, such as AD460L. What do they mean?

NC (Non-compliance): Unconventional books
It shows that the Lexile level of this book is much higher than the average level of the target group of this book, and it is suitable for people with higher level of the same age group to read.
HL (High and Low): A book with high interest but low difficulty.
Compared with NC, this kind of books means that the language of the book is easy to understand, and its Lexile level is far below the average level of the target group of the book, which is suitable for senior students with low reading ability.

GN (comic novel): comic book or comic book.

This kind of low-level reading materials usually have fewer words, so it is impossible to give specific blue thinking level values.
NP (non-prose): non-prose reading.
Non-popular styles, such as poetry, drama, songs, recipes, etc. Similarly, this kind of article can't evaluate lance.
Sweet spot (sweet spot)
Sweet Spot is a proper term of "Lance Graded Reading System", which refers to the range of Lance Index obtained by adding 50 and subtracting 100 on the basis of readers' own Lance Index.
For example, a reader's Lexile blue index is 1240L, and his sweet spot is1140-1290l.
