Formula
Weighted Level = Sum of (Level Number x Items at Level) / Total Items
Each Bloom level is assigned a number (Remembering=1 through Creating=6). The weighted level is the sum of each level number multiplied by the number of items at that level, divided by total items. HOT Ratio = (Analyzing + Evaluating + Creating items) / (Remembering + Understanding + Applying items). Higher weighted levels and HOT ratios indicate more cognitively demanding curricula.
Worked Examples
Example 1: Introductory Chemistry Exam Analysis
Problem:A chemistry midterm has 50 questions distributed as: 12 Remembering, 13 Understanding, 10 Applying, 8 Analyzing, 5 Evaluating, 2 Creating.
Solution:Total Allocated = 12 + 13 + 10 + 8 + 5 + 2 = 50\nWeighted Level = (1x12 + 2x13 + 3x10 + 4x8 + 5x5 + 6x2) / 50\n= (12 + 26 + 30 + 32 + 25 + 12) / 50 = 137 / 50 = 2.74\nLower Order = 12 + 13 + 10 = 35 (70%)\nHigher Order = 8 + 5 + 2 = 15 (30%)\nHOT Ratio = 15 / 35 = 0.43
Result:Weighted Level: 2.74 (Intermediate) | LOTS: 70% | HOTS: 30% | HOT Ratio: 0.43
Example 2: Graduate Seminar Learning Objectives
Problem:A graduate seminar has 20 learning objectives: 2 Remembering, 3 Understanding, 3 Applying, 5 Analyzing, 4 Evaluating, 3 Creating.
Solution:Total Allocated = 2 + 3 + 3 + 5 + 4 + 3 = 20\nWeighted Level = (1x2 + 2x3 + 3x3 + 4x5 + 5x4 + 6x3) / 20\n= (2 + 6 + 9 + 20 + 20 + 18) / 20 = 75 / 20 = 3.75\nLower Order = 2 + 3 + 3 = 8 (40%)\nHigher Order = 5 + 4 + 3 = 12 (60%)\nHOT Ratio = 12 / 8 = 1.50
Result:Weighted Level: 3.75 (Intermediate-Advanced) | LOTS: 40% | HOTS: 60% | HOT Ratio: 1.50
Frequently Asked Questions
What is Bloom Taxonomy and how is it used in education?
Bloom Taxonomy is a hierarchical classification framework for cognitive learning objectives, originally developed by Benjamin Bloom and colleagues in 1956 and revised by Anderson and Krathwohl in 2001. The taxonomy identifies six levels of cognitive complexity, from lower-order thinking (Remembering, Understanding, Applying) to higher-order thinking (Analyzing, Evaluating, Creating). Educators use it to design learning objectives, create assessments at appropriate cognitive levels, and ensure curricula challenge students across the full spectrum of thinking skills. It is one of the most widely used frameworks in instructional design worldwide.
What are the six levels of Bloom Taxonomy in order?
The six levels of the revised Bloom Taxonomy, from lowest to highest cognitive complexity, are: Remembering (retrieving relevant knowledge from memory, including recognizing and recalling facts), Understanding (constructing meaning through interpreting, exemplifying, classifying, summarizing, inferring, comparing, and explaining), Applying (carrying out or using a procedure in a given situation), Analyzing (breaking material into constituent parts and detecting how parts relate to one another), Evaluating (making judgments based on criteria and standards), and Creating (putting elements together to form a coherent or functional whole, or reorganizing elements into a new pattern or structure).
How should assessment questions be distributed across Bloom levels?
The ideal distribution depends on the course level and goals. For introductory undergraduate courses, a common distribution is 30% Remembering, 25% Understanding, 20% Applying, 15% Analyzing, 5% Evaluating, and 5% Creating. For advanced courses, the distribution shifts upward: 10% Remembering, 15% Understanding, 20% Applying, 25% Analyzing, 15% Evaluating, and 15% Creating. Graduate-level courses should have 60% or more of assessments at the Analyzing level and above. The Higher-Order Thinking (HOT) ratio, which compares higher-order to lower-order questions, should ideally be at least 0.5 for introductory courses and 1.0 or higher for advanced courses.
How can I identify the Bloom level of a question or objective?
The most reliable method for identifying Bloom level is to examine the action verb used in the question or objective. Each level has characteristic verbs: Remembering uses define, list, recall, identify, and name. Understanding uses explain, summarize, describe, interpret, and paraphrase. Applying uses solve, demonstrate, calculate, use, and implement. Analyzing uses compare, contrast, categorize, examine, and differentiate. Evaluating uses judge, justify, critique, assess, and defend. Creating uses design, construct, develop, compose, and formulate. However, context matters since the same verb can operate at different levels depending on what the student is actually required to do.
