Instructional Strategies and Assessment
,This comprehensive assessment is designed to evaluate prospective high school teachers' mastery of content
area knowledge required for Illinois teacher licensure. The exam measures essential skills and knowledge
across multiple subject domains that high school educators must command to effectively teach secondary
students. The multiple-choice format includes both standalone questions and scenario-based items that
present real-world classroom situations. Emphasis is placed on applied professional knowledge, regulatory
compliance, ethical decision-making, and the ability to translate theoretical understanding into effective
instructional practice. Candidates will demonstrate competency in foundational theory, curriculum planning,
student assessment, legal requirements, and professional standards essential for success in Illinois high school
classrooms.
Section One: Questions 1–100
Question 1
A high school biology teacher is planning a unit on cellular respiration. Which of the following best represents
the primary energy molecule produced during this process?
A. Glucose
B. ATP
C. NADH
D. Pyruvate
🟢 B. ATP
🔴 RATIONALE: ATP (adenosine triphosphate) is the primary energy molecule produced during cellular
respiration. While glucose is the starting substrate and NADH and pyruvate are intermediates, ATP is the main
energy currency that cells use for metabolic processes.
,Question 2
In a mathematics classroom, a student struggles to understand why the sum of two negative numbers is always
negative. Which instructional approach would be MOST effective?
A. Providing additional practice problems
B. Using a number line visualization
C. Memorizing the rule through repetition
D. Assigning textbook reading
🟢 B. Using a number line visualization
🔴 RATIONALE: A number line visualization helps students conceptually understand that moving left
(negative direction) from a negative starting point results in a more negative value. This concrete representation
builds conceptual understanding rather than relying on rote memorization.
Question 3
According to the Illinois Learning Standards, which of the following is a key component of effective reading
instruction for high school students?
A. Focus solely on fiction texts
B. Explicit vocabulary instruction
C. Avoiding complex texts
D. Minimizing assessment
🟢 B. Explicit vocabulary instruction
, 🔴 RATIONALE: Explicit vocabulary instruction is a research-based component of effective reading
instruction. High school students encounter increasingly complex academic vocabulary, and explicit instruction
helps them comprehend challenging texts across content areas.
Question 4
A history teacher wants to help students analyze primary sources from the Civil War era. Which strategy would
BEST develop critical thinking skills?
A. Having students memorize dates and names
B. Comparing multiple perspectives from different sources
C. Reading a single textbook chapter
D. Watching a documentary without discussion
🟢 B. Comparing multiple perspectives from different sources
🔴 RATIONALE: Comparing multiple perspectives from primary sources develops critical thinking by
requiring students to evaluate bias, context, and reliability. This approach teaches historical inquiry skills
essential for understanding complex historical events.
Question 5
In a chemistry lab, a student needs to measure 25 mL of liquid with maximum precision. Which equipment
should be used?
