Question 1
A preschool in a primarily African American community has several students who speak in African American Vernacular English. The teachers are instructed to teach Standard English as a second language, focusing especially on syntactic and phonological differences. These instructions reflect:
◦ an additive approach to language education.
◦ a subtractive approach to language education.
◦ a phonemic approach to language education.
◦ a pragmatic approach to language education.
Question 2
The most effective response when preschoolers write with invented spelling is to:
◦ explicitly correct invented spelling so that children learn to spell the words correctly in the future.
◦ encourage invented spelling, because it is a part of the literacy learning process.
◦ avoid invented spelling by discouraging free writing activities.
◦ encourage invented spelling only when it reflects cultural and socioeconomic diversity.
