Multiple Intelligences Theory is a model introduced by Howard Gardner in his 1983 work, "Frames of Mind: The Theory of Multiple Intelligences". This theory posits that intelligence is not a single construct but rather that individuals possess multiple, independent intelligences. Gardner approaches intelligence with a meaning that extends beyond the traditional and narrow scope of verbal and mathematical abilities. According to Gardner, intelligence is defined as "the capacity to solve problems or to fashion products that are valued in one or more cultural settings," "the ability to generate effective solutions to problems encountered in real life," and "the skill to discover new or complex problems that require a solution". He later refined this definition to "a biopsychological potential to process information that can be activated in a cultural setting to solve problems or create products that are of value in a culture". The theory challenges the view that intelligence is fixed and can be measured by a single number (an IQ score), asserting instead that every individual has a unique intelligence profile and that these intelligences can be developed.

Historical Development

The traditional understanding of intelligence was shaped by attempts to measure it in the early 20th century. In 1904, the French Ministry of Education asked Alfred Binet and his colleagues to develop a tool to identify students at risk of academic failure at the primary school level. This work resulted in the development of the Binet-Simon Intelligence Scale, the first intelligence test. This test popularized the idea that human intelligence could be objectively measured and reduced to a single number known as the IQ (Intelligence Quotient). In this approach, intelligence was considered a fixed, unchangeable trait determined at birth. Traditional tests focused predominantly on measuring verbal and numerical competencies.

Howard Gardner set out to offer an alternative to this traditional view. Gardner's work gained momentum when he joined "Project Zero," a project that began at the Harvard Graduate School of Education in 1967. Through his neuropsychological research on brain-damaged adults and children, Gardner observed that cognitive abilities were located in different parts of the brain and that damage to one area might not affect other abilities. These findings, combined with syntheses from fields like anthropology, developmental psychology, and art education, led to the idea that intelligence is not unitary but multiple in structure.

In his 1983 book "Frames of Mind," Gardner initially identified seven basic areas of intelligence. He later added an eighth, "Naturalist Intelligence," in 1995 and opened a discussion for a ninth candidate, "Existential Intelligence," in 1999. The theory garnered more interest among educators than in the field of psychology and spread rapidly.

Theoretical Approaches

The Multiple Intelligences Theory is based on biological and cultural foundations.

Biological Foundations

The theory draws from the findings of neurobiological research. It is accepted that learning occurs as a result of changes in synaptic connections between cells. The view that the brain has a modular structure and that different cognitive functions are concentrated in specific brain regions forms the basis of the theory. For example, damage to Broca's area of the brain can impair an individual's ability to speak without affecting their ability to understand spoken language, which indicates that linguistic intelligence has a specific neurological basis. Gardner argued that each type of intelligence is associated with a different region of the brain.

Cultural Foundations

According to the theory, the development of intelligence and which types of intelligence that come to the fore are influenced by the values of the culture in which one lives. Each society values different talents and skills. The areas of intelligence supported by a society's cultural values have more opportunity to develop, while those not considered important may remain in the background. In defining intelligence, Gardner emphasized the "capacity to fashion products that are valued in one or more cultural settings," highlighting the determinative role of the cultural context.

Gardner defined specific criteria for a talent to be classified as an "intelligence." These criteria include conditions such as having its own symbol system, being valued in a cultural structure, being a means to produce goods or services, and being able to solve problems within it. Gardner stated that his deliberate use of the term "intelligence" instead of "talent" or "skill" was to remove these categories from the narrow confines of the traditional understanding of intelligence and to encourage people to think of these areas as types of intelligence.

The Multiple Intelligences Areas

The areas of intelligence defined by Gardner, which are present in every individual at different levels, are as follows:

^{The Multiple Intelligences Areas (Generated by Artificial Intelligence)}

Verbal-Linguistic Intelligence

The capacity to use language, both spoken and written, effectively. It includes skills such as thinking with words, grasping complex meanings in language, self-expression, storytelling, humor, and persuasion. Poets, writers, politicians, and journalists are examples of individuals with well-developed linguistic intelligence. This intelligence is associated with the frontal and temporal lobes of the left hemisphere of the brain.

Logical-Mathematical Intelligence

The ability to use numbers effectively, establish logical relationships, understand cause-and-effect connections, and solve abstract problems. It encompasses skills like calculation, classification, hypothesis formulation, and critical thinking. Scientists, mathematicians, engineers, and computer programmers are proficient in this area of intelligence. The left frontal and right parietal lobes of the brain are the centers for this intelligence.

Visual-Spatial Intelligence

The capacity to accurately perceive the visual and spatial world in the mind and to perform transformations based on these perceptions. It includes skills such as thinking in pictures, images, and shapes, perceiving three-dimensional objects, and finding one's way. Architects, painters, sculptors, sailors, and surgeons use this type of intelligence extensively. This intelligence is associated with the posterior regions of the right hemisphere of the brain.

Bodily-Kinesthetic Intelligence

The ability to skillfully use the body and its parts to express thoughts and emotions, solve problems, or create products. It includes physical skills such as coordination, balance, speed, flexibility, and manual dexterity. Dancers, athletes, actors, surgeons, and artisans are successful in this area of intelligence.

Musical-Rhythmic Intelligence

The capacity to perceive, discriminate, transform, and express musical forms. It includes sensitivity to rhythm, pitch, timbre, and melody. Musicians, composers, conductors, and singers are individuals with strong musical intelligence. This intelligence is associated with the right temporal lobe of the brain.

Interpersonal-Social Intelligence

The capacity to understand and interpret the moods, emotions, intentions, and motivations of others. It includes social skills such as empathy, effective communication, collaboration, and leadership. Politicians, teachers, psychologists, and sales professionals are skilled in this area of intelligence.

Intrapersonal-Personal Intelligence

An individual's capacity to understand their own inner world, emotions, strengths and weaknesses, desires, and intentions, and to use this knowledge to guide their life. It includes skills such as self-awareness, self-discipline, goal setting, and managing emotional responses. Philosophers, psychologists, and writers are examples of individuals with well-developed intrapersonal intelligence.

Naturalist Intelligence

The ability to recognize, understand, and classify living things in the natural environment. It includes skills such as recognizing flora and fauna, discerning patterns in the natural world, and sensitivity to the environment. Biologists, botanists, farmers, and hunters use this type of intelligence extensively.

Existential Intelligence

Proposed by Gardner as a ninth candidate intelligence, this type is the capacity to ponder deep and philosophical questions about the meaning of life, death, and human existence. Although its neurological basis has not yet been fully proven, it is thought to be related to fields such as philosophy and theology.

Application Areas and Educational Implications

The Multiple Intelligences Theory has had its greatest impact in the field of education. The theory provides a framework for educators to understand students' individual differences and to shape instruction according to these differences.

Curriculum Development and Teaching Methods

The theory argues that it is insufficient for educational programs to focus only on linguistic and logical-mathematical intelligences. Instead, it proposes the creation of multifaceted and enriched learning environments that encompass all areas of intelligence.

Lesson Design

Teachers can use a variety of methods and materials that appeal to different areas of intelligence when teaching a topic. For example, when teaching a history topic, activities such as maps (visual-spatial), songs of the period (musical), role-playing (bodily-kinesthetic), and group discussions (interpersonal) can be included.

Project-Based Learning

Student projects allow for the emergence of different talents and areas of intelligence. Projects enable students to solve a problem or create a product, which forms the essence of Gardner's definition of intelligence.

Learning Centers

Learning centers with materials for each area of intelligence can be created within the classroom. For example, a language center might contain books and word games, while a music center might have instruments and recording devices.

Apprenticeships

Gardner advocates for individualized programs where students can explore their talents by taking on apprenticeships in different fields (academic, artistic, physical) at school.

Assessment

The Multiple Intelligences Theory argues that traditional standardized tests (like IQ, SAT) measure only a narrow segment of intelligence and do little more than label students. Instead, it proposes "intelligence-fair" assessment methods aimed at identifying students' strengths and weaknesses to aid their development.

Performance Assessment

Assessment should be done by observing students' performance in tasks similar to real-life situations.

Portfolios

Portfolios consisting of students' work throughout the year (projects, writings, drawings, video recordings) are an effective tool for showing their development and progress in different areas of intelligence. This method involves students, teachers, and families in the assessment process.

The Role of the Educator and the School

In education based on this theory, the teacher plays a major role. The teacher must first recognize their own intelligence profile. They should be sensitive to students' individual differences and areas of intelligence and provide them with various learning options. According to Gardner, schools should take on new roles such as "assessment specialist" to identify students' intelligence profiles, "student-curriculum broker" to recommend courses and programs appropriate for these profiles, and "school-community broker" to connect students with professional opportunities in the community.
