The idea of developing and focusing on critical thinking skills can be attributed to several influential educational philosophers and psychologists throughout history. While it is difficult to pinpoint a single originator of the concept, here are a few notable contributors:


Socrates, the ancient Greek philosopher, emphasized the importance of questioning and challenging assumptions to arrive at deeper understanding. Through his method of Socratic questioning, he encouraged critical thinking and reasoning as a means to explore ideas and seek truth.

John Dewey:

John Dewey, an American philosopher and educational reformer in the late 19th and early 20th centuries, emphasized the significance of critical thinking in education. He believed that students should engage in active, hands-on learning experiences that fostered critical thinking, problem-solving, and reflection.

Jean Piaget:

Jean Piaget, a Swiss psychologist and pioneer in cognitive development theory, highlighted the role of critical thinking in children’s intellectual growth. Piaget’s theory proposed that children actively construct their understanding of the world through cognitive processes, including assimilation, accommodation, and logical reasoning.

Benjamin Bloom:

Benjamin Bloom, an American educational psychologist, developed Bloom’s Taxonomy in the 1950s, which categorized learning objectives and cognitive processes. Within his taxonomy, critical thinking skills were identified as higher-order thinking skills, including analysis, synthesis, and evaluation.

Edward Glaser:

Edward Glaser, an American educational psychologist, conducted extensive research on critical thinking in the 1940s and 1950s. His work laid the foundation for understanding the cognitive processes involved in critical thinking and the development of assessments to measure critical thinking skills.

These individuals, among others, have contributed to the recognition and promotion of critical thinking skills in educational contexts. Over time, educators, researchers, and practitioners have built upon their ideas to develop strategies, curriculum frameworks, and assessments to cultivate and assess critical thinking abilities in learners of all ages.

Introduction of Critical Thinking Skills in Schools:

The introduction and emphasis on the development of critical thinking skills in schools can be attributed to various educational reform movements and initiatives. Here are a few key milestones in the integration of critical thinking skills into school curriculam:

Progressive Education Movement:

In the late 19th and early 20th centuries, the Progressive Education Movement, led by educational reformers such as John Dewey, emphasized active learning, problem-solving, and critical thinking. These educators advocated for a shift from rote memorization to experiential learning that encouraged students to think critically and apply their knowledge.

Cognitive Revolution:

In the mid-20th century, the cognitive revolution in psychology led to a greater understanding of the cognitive processes underlying thinking and learning. Cognitive psychologists like Jean Piaget and Lev Vygotsky highlighted the importance of critical thinking in intellectual development and advocated for its integration into education.

Bloom’s Taxonomy:

In the 1950s, Benjamin Bloom and a team of educational psychologists developed Bloom’s Taxonomy, which classified learning objectives into cognitive domains. The taxonomy placed critical thinking skills, such as analysis, synthesis, and evaluation, at the higher levels of cognitive complexity, emphasizing their significance in education.

Educational Reforms and Standards:

In more recent years, educational reforms and the development of educational standards in many countries have emphasized the importance of critical thinking skills. For example, in the United States, the Common Core State Standards explicitly include critical thinking and problem-solving as essential skills for students across subjects.

21st Century Skills Movement:

With the increasing recognition of the skills needed for success in the 21st century, including adaptability, problem-solving, and critical thinking, educational initiatives have focused on integrating these skills into the curriculum. Organizations such as the Partnership for 21st Century Skills and the World Economic Forum have highlighted the importance of critical thinking in preparing students for the demands of the modern world.

As a result of these developments, schools and educators have incorporated critical thinking skills into their teaching practices through various instructional approaches, curriculum design, and assessments. The goal is to equip students with the ability to analyze information, evaluate evidence, think critically, and solve complex problems, preparing them for lifelong learning and success in an ever-changing world.

Critical Thinking Skills; A brainy Overview:

Critical thinking skills begin to develop from an early age, even though the cognitive processes and complexity vary at different stages of childhood. Here’s an overview of how critical thinking skills develop in the early years:

Infancy (0-12 months):

During infancy, critical thinking skills are rooted in sensory exploration and early cognitive development. Infants engage in sensorimotor activities, exploring their environment through senses and developing cause-and-effect understanding. They observe and react to stimuli, imitate actions, and learn through trial and error.

Key Developments:

  • Developing sensorimotor skills and coordination.
  • Exploring objects and cause-and-effect relationships.
  • Beginning to imitate actions and behaviors.

Toddlerhood (1-3 years):

Toddlers enter a period of rapid cognitive and language development. They start to engage in pretend play, express their thoughts and emotions through words, and develop a rudimentary understanding of social interactions. Critical thinking skills emerge as they navigate their environment, solve simple problems, and engage in early reasoning.

Key Developments:

  • Developing language and communication skills.
  • Engaging in pretend play and imagination.
  • Beginning to solve simple problems and make connections.
  • Developing an understanding of basic social rules and interactions.

Preschool Years (3-5 years):

Critical thinking skills become more pronounced during the preschool years. Children demonstrate improved reasoning abilities, engage in imaginative play with complex storylines, and show curiosity about the world around them. They ask questions, analyze information, make predictions, and start to consider different perspectives.

Key Developments:

  • Developing reasoning and logical thinking skills.
  • Engaging in imaginative play with more complex scenarios.
  • Asking questions and seeking explanations.
  • Recognizing and categorizing objects and concepts.
  • Considering different viewpoints.

Early School Years (5-8 years):

As children enter the early school years, critical thinking skills become more refined. They become more adept at problem-solving, engage in more complex thinking tasks, and start to think more abstractly. They can analyze information, evaluate ideas, and make decisions based on evidence and logical reasoning.

Key Developments:

  • Improving problem-solving abilities.
  • Developing the ability to think critically about information.
  • Engaging in more complex reasoning and logical thinking.
  • Beginning to think abstractly and understand concepts like time and space.

It’s important to note that these developmental milestones are general guidelines, and individual children may vary in their progress. Providing stimulating environments, encouraging exploration, and supporting children’s natural curiosity through age-appropriate activities and experiences can nurture and enhance critical thinking skills from an early age.

Research on critical thinking skills in toddlers:

It is relatively limited compared to studies conducted on older children or adults. However, there are some studies that have explored aspects of critical thinking in early childhood. Here are a few key findings from research in this area:

Theory of Mind:

Theory of mind refers to the ability to understand and attribute mental states, such as beliefs, desires, and intentions, to oneself and others. Research has shown that the development of theory of mind in toddlers is associated with certain aspects of critical thinking, such as understanding that others may hold different perspectives or beliefs. This understanding lays the groundwork for later critical thinking skills.


Studies have examin ed toddlers’ problem-solving abilities and their approach to novel situations. Toddlers demonstrate early problem-solving skills by using trial-and-error strategies, making attempts to overcome obstacles, and engaging in creative problem-solving. These behaviors reflect aspects of critical thinking, such as perseverance and generating alternative solutions.

Reasoning and Causal Understanding:

Toddlers begin to develop an understanding of cause and effect relationships and engage in simple forms of logical reasoning. For example, they may recognize that certain actions lead to specific outcomes. This early reasoning ability contributes to the foundation of critical thinking by fostering the ability to make connections and draw logical inferences.

Executive Function Skills:

Executive function skills, including working memory, inhibitory control, and cognitive flexibility, are closely associated with critical thinking. Research suggests that the development of executive function skills in toddlers is linked to later critical thinking abilities. These skills enable toddlers to manage their attention, regulate impulses, and shift between different perspectives, supporting their emerging critical thinking capabilities.

Language Development:

Language plays a crucial role in the development of critical thinking skills. Toddlers’ language skills, including vocabulary growth, sentence complexity, and conversational abilities, are associated with their ability to express and understand complex thoughts, engage in reasoning, and engage in collaborative problem-solving.

While research in this area is ongoing, these studies highlight important aspects of critical thinking that emerge during the toddler years. Early experiences and supportive environments that encourage exploration, problem-solving, and language development can lay a solid foundation for the development of critical thinking skills in later childhood and beyond.

Higher order thinking skills associated with critical thinking skills:

Higher order thinking refers to cognitive processes that involve complex mental operations beyond basic recall and comprehension. In the context of critical thinking, higher order thinking skills encompass the ability to analyze, evaluate, synthesize, and create. These skills go beyond simple understanding and require learners to engage in deeper levels of thinking to solve problems, make connections, and generate original ideas. Here are some key higher order thinking skills associated with critical thinking:


This skill involves breaking down information into its component parts, examining relationships, identifying patterns, and discerning underlying meanings or causes. It requires learners to examine information critically and make connections between different pieces of evidence or concepts.


Evaluation involves assessing the validity, credibility, or quality of information, arguments, or solutions. Learners with strong evaluation skills can analyze the strengths and weaknesses of different perspectives, judge the reliability of sources, and make informed judgments or decisions based on evidence.


Synthesis refers to the ability to combine or integrate ideas, information, or elements from various sources to create new understanding or solutions. Learners who excel in synthesis can generate innovative ideas, construct coherent arguments, or develop novel approaches to solving problems.


Problem-solving is a higher order thinking skill that requires learners to define problems, analyze their components, generate potential solutions, and evaluate their effectiveness. It involves applying critical thinking strategies to identify and implement the most appropriate solutions to complex problems.


While often associated with the arts, creativity is an essential component of critical thinking. It involves thinking outside the box, generating original ideas, and approaching problems from unconventional angles. Creative thinking allows learners to explore diverse perspectives and come up with innovative solutions.


Metacognition is the ability to think about one’s own thinking processes. It involves self-awareness, reflection, and self-regulation of learning. Learners who possess strong metacognitive skills can monitor their own thinking, evaluate their strategies, and make adjustments to improve their critical thinking abilities.

These higher order thinking skills are interrelated and mutually reinforcing. Developing and honing these skills through targeted instruction, practice, and real-world applications can enhance students’ ability to think critically, solve complex problems, and become independent learners prepared for the challenges of the 21st century.
