Study Notes

Item Analysis for Exam Preparation

Item Analysis: The process of analyzing student responses to individual test questions, used to evaluate the quality of exam items and improve test design while upholding academic integrity.
Purpose: Evaluate the quality of exam items and improve test design.
Focus Areas: Item Difficulty, Item Discrimination, Item Distractors.
Item Difficulty: Assess whether a question is too easy or too hard.
Item Discrimination: Determine if a question differentiates between students who understand the material and those who do not.
Item Distractors: Evaluate whether incorrect options effectively function as distractors.

Procedure for Item Analysis

Identify the Upper and Lower Groups: Select the top and lowest 10 scorers, excluding other test-takers.
Create a Chart: Construct a grid with student names on the left and item numbers across the top, and include correct answers for each item.
Record Student Answers: List answers for the top and bottom 10 students; only enter incorrect answers (leave blank for correct responses).
Calculate Scores: Count how many in each group answered each item correctly, labeling RUR_URU (correct responses in the upper group) and RLR_LRL (correct responses in the lower group).

Indices for Evaluation

Difficulty Index: Formula: (RU+RL)/20, represents the proportion of students who answered the item correctly.
Discrimination Index: Formula: (RU-RL)/10, measures how well the item differentiates between high-performing and low-performing students. Higher values indicate better discrimination.

Second Chart Construction

Plot difficulty and discrimination indices in a chart.
Row 1: Maximum possible discrimination indices, for each item difficulty level.
Row 2: Observed difficulty level (measured difficulty of each item).
Discrimination index is placed in the column corresponding to difficulty level.

Interpreting Results

Medium Difficulty: Best items for assessing students, allowing discrimination between high and low performers.
Discrimination Rules:
- Very Discriminating: Near maximum possible index.
- Moderately Discriminating: About half the maximum possible.
- Weak Item: About a quarter of the maximum possible.
- Non-Discriminating Item: Index near zero.
- Negative Index: Indicates a bad item, delete if less than -0.10.

Evaluating Distractors

Ensure all distractors attract at least some test-takers.
Distractors that pull high-performing students lower need revision.
Analyze if distractors are clear and educationally significant.

General Guidelines for Writing Test Items

Purpose: Test items should accurately assess student knowledge and skills, align with learning objectives, and reduce ambiguity or bias.

Structure of a Multiple-Choice Item

Stem: The part of the item that sets up the problem or asks the question.
Alternatives: Responses provided to answer the stem, including the correct answer and distractors (plausible incorrect responses).

Key Considerations in Writing Multiple-Choice Items

Avoid Triviality: Questions should be meaningful and test significant concepts, not superficial details.
Reduce Guessing: Distractors should be plausible.
Clarity: Use clear and concise language.
Relevance: Ensure the question aligns with instructional objectives.

Guidelines for Alternate-Response Items

These are True/False or Yes/No types.
Challenges: Ambiguity and susceptibility to guessing.

Example of Analogy Test Items

Direct Comparison: Using a stem and alternatives, provide a comparison.

Review Questions to Consider

What are the basic principles of testing for classroom tests?

Table of Specifications (TOS)

Purpose: Outlines the topics covered and their weight in the test, ensuring balanced representation of content.

Best Practices for Creating Test Item Instructions

Write Clear Instructions: Specify the task, number of items, and any limitations.
Ensure Item Relevance: Questions must align with learning objectives and avoid trivia.

Focus on Higher-Order Thinking

Use Bloom's Taxonomy: Questions should evaluate knowledge, comprehension, application, analysis, synthesis, and evaluation.

Guidelines for Multiple-Choice Items

Guidelines for multiple-choice format.

Alternate Test Formats:

True/False: Effective for factual knowledge, but higher risk of guessing.
Matching Type: Useful for relationships between terms and definitions.
Essay Questions: Assess deep understanding and critical thinking.

Analyzing Test Results

Item Analysis: Evaluate item difficulty and discrimination.
Revise questions based on performance.

Key Takeaways

Well-constructed tests align with learning objectives and provide fair assessment.
Use a mix of item types (e.g., multiple choice, true/false) to assess various levels of thinking.

Administering and Scoring Paper-and-Pencil Tests

Pre-Administration Checklist: Ensure well-lit and ventilated testing area; proper materials are available; minimize distractions.
Key Areas to Address: Physical setting (ventilation, lighting), Psychological setting (calm environment), and careful preparation to avoid issues.
Strategies During Testing: Time management, maintaining order, minimizing distractions, and student preparation (providing directions).
Guidelines for Scoring Tests: Ensure objective scoring practices with rubrics for subjective items, use answer keys and templates for objective-type questions, and provide feedback.

Additional Tips for Administering Tests

Accommodating Diverse Learners: Be mindful of students with special needs.
Post-Test Practices: Secure materials and analyze to provide insights.
Validity and Reliability: Ensure test items are accurate and consistent to measure what they intend.
Ethical Considerations: Maintain test integrity (no favoritism, leakage).
Legal Compliance: Follow all relevant institutional or governmental policies.
