PSYC 3377 Chapter 11: True-False Tests Study Notes
Chapter 11: True-False Tests
Overview of True-False Items
- Definition: True-False items are used to assess achievement when there is a clear distinction between two alternates.
- Examples of Alternates:
- True–False
- Right–Wrong
- Yes–No
- Like–Dislike
- Writing True-False Questions:
- It might seem easy to write T/F items, but there is little space for precision.
Guidelines for Writing True-False Tests
- Declarative Sentences:
- Must state as declarative sentences; avoid phrasing such as “Is it true or false?”
- Example of a poor question: "Is it true or false that a leap year occurs every 4 years?"
- Focus on clear choices in a binary format.
Specificity in Topics
- Focus on One Topic/Concept:
- Example of a well-structured True-False item:
- True or False? A roux can be prepared using fat and flour.
- Avoid broad or overly general statements.
Avoiding Misleading Statements
- Avoid Statements of Opinion:
- Example of an opinion question: "In the video, I liked the way the teacher handled the interaction."
- Revised example: Instead, frame it to ask about specific facts.
- Beware of Double Negatives:
- Example of a bad format: "Yes or No? Neither Technique #1 nor Technique #2 should be used with caution."
- Revised to: "Yes or No? Technique #1 should be used with caution."
Qualifiers and Construct Length
- Caution with Qualifiers:
- Words such as always, never, and sometimes can mislead students.
- Equal Number of Items:
- Ensure the test contains an equal number of true and false items.
- Complex Material:
- Do not include overly complex material, which may not suit the T/F format.
Advantages and Disadvantages of True-False Tests
Advantages
- Convenience in Writing: True-False tests are generally easier to write.
- Ease of Administration: Simple to administer to students.
- Scoring Efficiency: Quick and straightforward to score.
- Time Efficiency: Students can answer a greater number of T/F questions in the same time compared to multiple-choice (MC) questions.
Disadvantages
- Reliance on Memorization: True-False tests emphasize memorization of facts rather than deeper understanding.
- Guessing Factor: The correct answer can often be guessed by students, leading to potential inaccuracies in knowledge assessment.
- Lower-Level Knowledge Measurement: T/F items are generally ineffective for assessing higher-level knowledge or comprehension skills.
Common Issues with True-False Items
- Example Statements:
- "Do you think the Raiders will win the Superbowl this year?"
- "Cold fusion always works."
- "Students would not be better off if they couldn’t take advantage of school tutoring."
- "Health care and childcare are major concerns for our society."
Variations of True-False Items
Confidence-Weighted True-False Items (CTF)
- Definition: CTF items gauge student confidence in their answers.
- Example Categories:
- I am sure the statement is true.
- I think the statement is true, but I am unsure.
- I think the statement is false, but I am unsure.
- I am sure the statement is false.
- Reference: Dutke & Barenberg (2015).
Research on CTF Items
- Learning Progress Sensitivity: Study by Dutke and Barenberg (2009) showed:
- Mid-semester, 20 CTF items divided into:
- 10 items on material already covered.
- 10 items on upcoming material.
- Results indicated higher performance on previously covered items compared to new content.
- End-Semester Assessments: Same set administered at the semester's end showed an increase in both correct and confident answers.
Predictive Validity of CTF Items
- Correlation with Essay Questions: CTF items showed reasonable correlation with performances in essay questions on the same content.
- Influence on Score Range: Predictive ability was affected by the score range in essays.
- Reduction of Guessing Impact: CTF items provide additional insight into teaching and testing methods, reducing guessing concerns.
Multiple True-False Items (MTF)
- Format: MTF items resemble MC questions but consist of a stem followed by several statements for evaluation as T/F.
- Benefits: MTF format can mitigate common test-taking strategies that depend on comparing options.
- Study Findings:
- Couch, Hubbard, & Brassil (2018) found that MTF questions allow students to answer more items in the same timeframe as MC questions, providing deeper insights into their understanding.
