Answer to Question 1
Recommended practices could include language that is recorded for children to read, use of word banks, creative writing exercises, oral reading exercises, etc. Practices to avoid would include strategies that do not value or come from the child's language, such as the repetitive reading of a vocabulary-controlled book.
Answer to Question 2
The bottom-up curriculum explanation should include a discussion of the materials, strategies, and environment in which students are asked to decode letters and words before they can construct meaning. In the bottom-up approach there would be an instructional emphasis on letter and word identification as well as an assessment of discreet skills. A top-down teacher's approach to curriculum would focus on keeping language whole as opposed to severing it into discrete pieces. In a top-down approach, classrooms are often learning communities where children learn to make sense of both oral and written language.
