To examine this, she decides to use her own classroom of six students. Student are given a list of 20 sight words they are asked to learn by reciting them on Monday and Tuesday. As they recite each word, one of three feedback conditions is given: a) no verbal feedback, b) positive comment after each wor c) negative comment after each word. On Wednesday, a reading test is given individual to each student. Each student receives all three feedback conditions in random order ov a three-week period. It is hypothesized that the number of sight words read correctly will be influenced by the type of feedback they received during learning.
