Lower-order thinking skills 

Updated October 2026 · reviewed for today

In short

Lower-order thinking skills are the foundation levels of Bloom’s taxonomy: remembering, understanding and applying, below analysing, evaluating and creating. Benjamin Bloom and colleagues published the original taxonomy in 1956; Lorin Anderson and David Krathwohl led a revision in 2001 that renamed the levels as verbs.

How it works

01

Remember

Retrieve relevant knowledge from memory, such as definitions, dates or formulas.

02

Understand

Build meaning from information: summarise, classify, compare or explain.

03

Apply

Carry out or use a procedure in a given situation, such as solving a standard problem.

04

Base for higher order

Analysing, evaluating and creating depend on knowledge that has been remembered, understood and practised.

Where you see it today

AI as a crutch in learning

In a field experiment with high school maths students, those given an unguarded GPT-4 tutor did better while they had it, then did worse than students who never had access once it was removed. A version with learning safeguards largely avoided the drop (Bastani et al., 2025).

Knowledge workers and effort

A survey of knowledge workers found that higher confidence in generative AI was associated with less critical thinking, and that AI shifts effort toward verifying, integrating and overseeing output (Lee et al., 2025).

Cognitive offloading

A mixed-methods study found a negative correlation between frequent AI tool use and critical-thinking scores, mediated by offloading thinking to the tools (Gerlich, 2025). The evidence is correlational, so cause and effect are not settled.

Verification needs the basics

To check an AI answer, people need enough remembered and understood knowledge to notice when it is wrong. Lower-order skills become the base for judging output rather than the end goal.

How to use it

• Before using AI on a task, check you can explain the core idea without it.
• Use AI to quiz yourself on facts and procedures, not only to produce answers.
• In training, have people solve a few standard problems by hand before giving them AI tools.
• When reviewing AI output, ask which facts you would need to know to spot an error.
• Design assessments that mix recall with tasks that require judgement, so both levels are practised.

The Business Engineer lens

AI now performs much lower-order work quickly, which moves human value toward judgement, synthesis and decisions. The Business Engineer argues that cognitive range, moving between detail and the big picture, is the meta-skill of the AI era, and that range still needs a solid base.

Frequently asked questions

What are lower-order thinking skills?

The first three levels of Bloom's revised taxonomy: remembering, understanding and applying knowledge.

What is the difference between lower- and higher-order thinking?

Lower-order skills recall, explain and apply knowledge; higher-order skills analyse, evaluate and create, and rely on the lower levels.

Who created Bloom's taxonomy?

Benjamin Bloom and colleagues published it in 1956; Lorin Anderson and David Krathwohl led the 2001 revision.

Does AI make lower-order skills obsolete?

No: research suggests relying on AI without safeguards can weaken learning, and people need basic knowledge to check AI output.

Lower-order thinking skills represent the building blocks of cognition and are characterized by their simplicity and directness. These skills involve basic mental operations that facilitate the initial acquisition and understanding of information. Key components of lower-order thinking skills include:

1. Observation: The ability to gather information through sensory perception, including sight, sound, touch, taste, and smell. Observation is the first step in processing external stimuli.
2. Memorization: The capacity to store and recall information. Memorization involves encoding details into memory and retrieving them when needed.
3. Comprehension: The skill of understanding and interpreting information. Comprehension goes beyond memorization by enabling individuals to grasp the meaning and significance of what they have learned.
4. Application: The ability to use acquired knowledge and skills to solve straightforward problems or perform tasks. Application involves transferring what has been learned to practical situations.

The Significance of Lower-Order Thinking Skills

While lower-order thinking skills may appear basic, they play a crucial role in cognitive development and lay the groundwork for higher-order thinking. Here’s why these skills are significant:

1. Foundation for Learning

• Lower-order thinking skills are the entry point to learning. They enable individuals to engage with new information, process it, and make it accessible for further cognitive processing.

2. Information Absorption

• Observation and memorization are essential for absorbing and retaining information. Without these skills, individuals would struggle to grasp basic facts and concepts.

3. Language Development

• Comprehension is central to language development. It allows individuals to understand spoken and written language, paving the way for effective communication.

4. Problem-Solving Prerequisite

• Application skills are a prerequisite for problem-solving. Without the ability to apply knowledge, individuals would struggle to address everyday challenges.

5. Cognitive Development

• Lower-order thinking skills form the foundation upon which higher-order thinking skills are built. They provide the necessary scaffolding for complex cognitive processes.

Strategies for Fostering Lower-Order Thinking Skills

Fostering lower-order thinking skills is essential for cognitive development. Here are strategies that individuals and educators can use to nurture these skills:

1. Encourage Active Observation

• Encourage individuals to actively observe their surroundings. Ask questions about what they see, hear, or experience to promote sensory perception.

2. Practice Memorization Techniques

• Teach memory-enhancing techniques such as visualization, repetition, and mnemonic devices. These strategies can improve memorization and retention.

3. Promote Reading

• Reading is a valuable way to develop comprehension skills. Encourage regular reading of diverse materials to enhance understanding and interpretation.

4. Real-Life Application

• Encourage individuals to apply what they learn in practical situations. This could involve solving everyday problems or using new knowledge in real-life scenarios.

5. Use Multisensory Learning

• Engage multiple senses during learning activities. Incorporate visuals, auditory elements, and hands-on experiences to reinforce lower-order skills.

6. Encourage Recall

• Encourage individuals to recall and discuss what they have learned. This reinforces memory and comprehension by requiring active engagement.

Lower-Order Thinking Skills in Education

Lower-order thinking skills play a pivotal role in education, particularly in the early stages of learning. Here’s how these skills manifest in educational settings:

1. Early Learning

• In early childhood education, lower-order thinking skills are foundational. Observing, memorizing, and comprehending basic information are essential for future academic success.

2. Reading

• Reading comprehension is a vital component of education. It involves understanding and interpreting written texts, which requires well-developed lower-order skills.

3. Building Blocks

• Lower-order thinking skills provide the building blocks upon which more advanced cognitive processes, such as critical thinking and problem-solving, are constructed.

4. Skill Progression

• Educational curricula often scaffold learning, gradually moving from lower-order to higher-order thinking skills as students progress through grade levels.

5. Preparation for Higher-Order Thinking

• Proficiency in lower-order skills prepares students for the challenges of higher-order thinking. Without a strong foundation, higher-level cognitive processes can be challenging.

Lower-Order Thinking Skills in Everyday Life

The significance of lower-order thinking skills extends far beyond the classroom. These skills are essential in various aspects of everyday life:

1. Information Processing

• Lower-order skills are crucial for processing and making sense of everyday information, such as news, instructions, and directions.

2. Decision-Making

• Even basic decision-making relies on comprehension and application skills. Individuals must understand options and apply their knowledge to choose wisely.

3. Problem Solving

• Everyday problem-solving often involves applying existing knowledge to resolve issues or navigate daily challenges.

4. Communication

• Effective communication requires comprehension and application skills. Individuals must understand messages and apply appropriate responses.

5. Learning

• Lifelong learning relies on lower-order thinking skills for absorbing new information and adapting to changing circumstances.

Challenges in Developing Lower-Order Thinking Skills

While lower-order thinking skills are essential, they are not without challenges:

1. Overemphasis: Overemphasizing lower-order skills at the expense of higher-order thinking can hinder cognitive development.
2. Technological Impact: The digital age has altered how individuals absorb and process information, potentially affecting traditional lower-order thinking skills.
3. Cultural Differences: Cultural norms and practices can influence the development and importance placed on lower-order thinking skills.

Conclusion

Lower-order thinking skills are the foundation of cognitive development, serving as the entry point for learning and understanding. While these skills may appear basic, they are essential for progressing to more advanced cognitive processes. Whether in education or daily life, nurturing lower-order thinking skills is the first step toward developing a well-rounded and capable mind. By encouraging observation, memorization, comprehension, and application, individuals can strengthen these foundational skills and pave the way for higher-order thinking and problem-solving. In the complex landscape of cognition, lower-order thinking skills remain the steadfast bedrock upon which cognitive excellence is built.
