Structured literacy (SL), according to the International Dyslexia Association (which coined the term), is the systematic teaching of reading that focuses on the following elements: [7]
SL is taught using the following principles: [1]
The International Dyslexia Association provides a detailed outline of its Key Performance Standards of its Knowledge and Practice Standards for Teachers of Reading. [8]
There is general agreement that SL is beneficial for all early literacy learners, especially those with reading disabilities such as dyslexia. [14] However, according to professor Mark Seidenberg, while SL is necessary for students with special needs (e.g., to overcome dyslexia), it may not be required for the general student population beyond the early literacy years. He suggests that teachers strike a balance between implicit instruction and explicit instruction, with explicit instruction for all students at the start, followed by implicit instruction for all students except dyslexics (who continue to receive explicit instruction as required). [15]
SL has many of the elements of systematic phonics and few of the elements of balanced literacy. The following is an explanation of how Structured literacy is different from Balanced literacy: [1]
| Feature | Structured literacy | Balanced literacy |
|---|---|---|
| Basis | Science of reading [16] | Whole language [16] |
| Areas covered | Phonology, phonemic awareness, sound-symbol association (phonics), syllables, morphology, syntax, and semantics [17] | Learn from exposure, reading, instruction, and support in multiple environments [17] |
| Teaching method | Direct, explicit, systematic, cumulative, and multisensory [17] Mostly teacher-led (e.g., The teacher leads the students through decoding activities.) [18] Lessons involve phonics and word reading, from easier to more difficult [18] Corrective feedback: students are asked to "sound-out" the word [18] | Implicit, constructivist, and less structured [19] Often student-directed (e.g., independent learning, students choose reading material, etc.) [18] Lessons relate to comprehension of books or literature themes. [18] Corrective feedback: students are asked "does that make sense", and are told to check the cues (e.g., pictures, first letter, etc.) [18] |
| Phonics | Taught via the alphabetic principle, systematically, including the most frequent phonemes (sounds) and graphemes (letters), beginning with the easiest and progressing to the more complex [17] | Taught as needed via mini-lessons, or not at all [17] |
| Text for reading instruction | Decodable text until grade 2 [18] | Leveled text, but not corresponding to phonics taught [18] |
| Reading | decoding and sounding out words [17] | read the whole word using cues (context, word analogies, and pictures) to guess the word [17] |
| Effectiveness | a mean unweighted effect size of .47, and a fixed weighted mean effect size of .44. Structured literacy approaches "tend to yield larger positive effects on student learning compared to balanced literacy approaches". (meta-analysis 2024) [20] | a mean unweighted effect size of .21, and a weighted mean effect size of .33. [20] |
