EXAM QUESTIONS
QUESTION 1
Once students decode well, which statement describes the relationship between vocabulary and reading
comprehension?
CORRECT ANSWER
Vocabulary is the best single predictor of reading comprehension.
RATIONALE: When students can decode text accurately, the most significant challenge in reading comprehension often lies
in understanding unfamiliar words and their meanings, as vocabulary knowledge directly influences the ability to connect
with the text's ideas and concepts. By possessing a strong vocabulary, students can better navigate the nuances of
language and make connections between words, ideas, and context, ultimately facilitating more effective reading
comprehension.

, QUESTION 2
In teaching the word invisible, the teacher broke it into the parts in - vis - ible and talked about the
meanings of the parts. Which aspect of language was emphasized?
CORRECT ANSWER
morphology
RATIONALE: The teacher emphasized the aspect of language known as morphology, which is the study of the internal
structure of words and how their component parts, such as prefixes, roots, and suffixes, contribute to their meaning. By
breaking down the word "invisible" into its constituent parts (-vis-ible) and discussing their meanings, the teacher
highlighted the way in which morphology helps to explain the meaning of complex words.
QUESTION 3
The Hart and Risley study (1995) identified a "30-million-word" gap. This gap refers to:
CORRECT ANSWER
the difference in the number of words heard by preschool children raised in high- and low-language family
environments.
RATIONALE: The Hart and Risley study (1995) identified a "30-million-word" gap because it compared the number of words
spoken to preschool children in high-language and low-language family environments, revealing a significant disparity in the
amount of verbal stimulation they received. This gap in verbal interaction is a key factor in the study's findings, highlighting
the profound impact of early language exposure on a child's cognitive and linguistic development.
QUESTION 4
Which of the following is least likely to narrow the vocabulary gap between language-rich and language-
poor students?
CORRECT ANSWER
watching children's television programs
RATIONALE: Watching children's television programs is the correct answer because it typically involves passive reception of
language, which is less effective than interactive dialogue or reading for closing vocabulary gaps. Language-rich and
language-poor students may benefit equally from watching TV, as they are not actively engaging with or practicing new
vocabulary in the same way as through reading or conversation.
