Description¶

Alphabet knowledge is knowing the names, written forms and sounds of letters, including letter combinations that represent a single sound. Print awareness is the understanding that print carries meaning and has different functions, and of how it works on the page (that text is read in a set direction, that words are separated by spaces, and so on), something experienced readers forget they had to learn. Both are measured in early childhood: alphabet knowledge by asking children to name and sound out randomly ordered upper- and lower-case letters, print awareness by informal assessments in which a child handles a book.

These are among the earliest text-based foundations of literacy. Children do not pick up reading the way they pick up speech; they must be taught to connect written symbols to sounds according to their language's writing system. Letter knowledge is closely tied to remembering written words and is described as one of the best predictors of learning to read, and recognising and writing letters is part of early writing. Exposure to print helps children understand what writing is and what it is for.

Both factors come from the LVN's PK-3 literacy area. They lead into phonological awareness and decoding, and sit within the wiki's broader reading and language page.

Implications¶

Context¶

Matters in preschool and the first years of school, and for older beginning readers.
Shared reading and other home literacy activities give children opportunities to build print awareness and letter knowledge.
Children who enter school with less print exposure at home, which often reflects family circumstances, may need more of it in class.

Target Learners¶

Preschool, kindergarten and early-elementary children.
Children with weak phonological awareness, who often also find print awareness difficult.

Target Learning Objectives¶

Learning to read: decoding and word recognition.
Early writing and letter formation.
Understanding the purposes of print.

Measures¶

Concepts About Print (CAP) (Clay, 2000): informal assessment of print awareness for kindergarten and first-grade children.
Phonological Awareness Literacy Screening (PALS) (Invernizzi, Meier, Swank & Juel, 2004): includes a subtest asking for the names and sounds of randomly ordered upper- and lower-case letters.

Phonological Awareness: letter knowledge predicts phonological skills such as rhyming and blending, and weak phonological awareness goes with weak print awareness.
Decoding: decoding depends on knowing letters and their sounds.
Writing Skills: print awareness and letter-name knowledge contribute to producing written words and early writing.
Home Learning Environment: reading with children and other home literacy activities are associated with growth in letter knowledge and print awareness.
Socioeconomic Status: children from lower-income homes often start kindergarten with less print awareness, likely reflecting fewer opportunities with print rather than the income itself.
Processing Speed: faster processing speed helps children acquire letter knowledge and print awareness.
Executive Function: inhibition skills in kindergarten are positively linked to letter knowledge.
Self-Regulation: self-regulation in preschool predicts letter knowledge in kindergarten.
Working Memory: verbal short-term memory at age four predicts letter knowledge at the end of kindergarten.
Social Supports: children with positive peer relationships often have better letter knowledge.
Visual Processing: visual processing aids learning the shapes of letters.
