According to research by Gambrell, Wilson, and Gantt (1981 ) and Nation (2001), students make the most progress when they are reading materials in which they know ________ percent of the words

Question

A) 99 to 100
B) 85 to 90
C) 95 to 98
D) 80 to 85

Answer 1

C / Explanation:
A) Reading Recovery and some other approaches place the instructional level at 90 to 94 percent. However, research indicates that students do best when they know 95 to 98 percent of the words (therefore about 2 to 5 percent of the words are difficult for them). Knowing 100 percent of the words is an indicator that the students know the material very well and would not be challenged by it.
B) Reading Recovery and some other approaches place the instructional level at 90 to 94 percent. However, research indicates that students do best when they know 95 to 98 percent of the words (therefore about 2 to 5 percent of the words are difficult for them). Knowing 85 to 90% of the words is not adequate.
C) Reading Recovery and some other approaches place the instructional level at 90 to 94 percent. However, research indicates that students do best when they know 95 to 98 percent of the words (therefore about 2 to 5 percent of the words are difficult for them).
D) Reading Recovery and some other approaches place the instructional level at 90 to 94 percent. However, research indicates that students do best when they know 95 to 98 percent of the words (therefore about 2 to 5 percent of the words are difficult for them). Knowing 80 to 85% percent of the words is much too low.
