(Questions 1-15)
Q1. A kindergarten ELL student points to a picture of a dog and says, "Doggy runned."
This error primarily demonstrates difficulty with which of the following?
A) Phonology
B) Morphology
C) Syntax
D) Semantics
Answer: B) Morphology
Rationale: The student used "runned" instead of "ran," indicating overgeneralization of
the regular past tense morpheme "-ed." This is a morphological error, not phonological
(sounds), syntactic (word order), or semantic (meaning).
,Q2. An ELL student who can understand grade-level content when it is simplified and
supported with visuals but struggles to produce complex sentences independently is
most likely at which stage of second language acquisition?
A) Pre-production
B) Early production
C) Speech emergence
D) Intermediate fluency
Answer: D) Intermediate fluency
Rationale: At the intermediate fluency stage, students have good comprehension but
still make errors in complex language production and may struggle with academic
language.
Q3. A teacher notices that a Spanish-speaking ELL student frequently says, "I have 10
years" instead of "I am 10 years old." This error is best explained by:
A) Interference from the student's first language
B) A developmental delay in language acquisition
C) A lack of vocabulary in English
D) A cognitive processing disorder
Answer: A) Interference from the student's first language
Rationale: In Spanish, age is expressed as "Tengo 10 años" (literally "I have 10 years").
This is a classic example of L1 interference (negative transfer) where the student applies
Spanish grammar rules to English.
Q4. According to Krashen's Affective Filter Hypothesis, which of the following classroom
conditions would most effectively lower an ELL student's affective filter?
,A) Correcting every grammatical error immediately
B) Requiring oral presentations in front of the class
C) Creating a low-anxiety environment with meaningful, comprehensible input
D) Administering weekly vocabulary quizzes
Answer: C) Creating a low-anxiety environment with meaningful, comprehensible
input
Rationale: Krashen's Affective Filter Hypothesis states that anxiety, low self-esteem, and
lack of motivation create a "filter" that blocks language acquisition. A supportive, low-
anxiety environment lowers the filter and facilitates acquisition.
Q5. Which of the following best describes the difference between BICS (Basic
Interpersonal Communication Skills) and CALP (Cognitive Academic Language
Proficiency) as defined by Cummins?
A) BICS develops after CALP in most ELL students
B) BICS is context-reduced, while CALP is context-embedded
C) BICS is social language that develops in 1-3 years, while CALP is academic language
that takes 5-7 years
D) BICS requires higher-order thinking skills than CALP
Answer: C) BICS is social language that develops in 1-3 years, while CALP is
academic language that takes 5-7 years
Rationale: Cummins distinguished between BICS (everyday conversational fluency, 1-3
years) and CALP (academic language proficiency, 5-7 years). CALP is cognitively
demanding and context-reduced.
, Q6. An ESL teacher is planning a lesson on the water cycle for a class with ELLs at
various proficiency levels. Which strategy would best support the students'
comprehension?
A) Providing a lengthy written explanation of the water cycle
B) Using visuals, diagrams, and hands-on activities alongside verbal instruction
C) Having students copy definitions from the textbook
D) Asking students to write a research paper on the water cycle
Answer: B) Using visuals, diagrams, and hands-on activities alongside verbal
instruction
Rationale: Comprehensible input—using visuals, realia, and hands-on activities—makes
content accessible to ELLs at various proficiency levels by providing multiple means of
understanding.
Q7. A fourth-grade ELL student writes, "The boy go to school yesterday." This error most
likely reflects:
A) A lack of understanding of English syntax
B) Difficulty with English verb morphology (tense marking)
C) A phonological processing disorder
D) Insufficient vocabulary knowledge
Answer: B) Difficulty with English verb morphology (tense marking)
Rationale: The error involves incorrect tense marking ("go" instead of "went"). This is a
morphological issue related to mastering English verb inflections, which is common for
ELLs.
