From Spearman's g-factor to Gardner's multiple intelligences and Sternberg's triarchic theory, compare 7 models of intelligence.
Intelligence theories try to define and measure how learners think (Gardner, 1983). Some theories, like Gardner's, suggest many types of intelligence, not just one score. Teachers can use different activities to engage learners' various strengths. Recognising strengths builds learner confidence and inclusion (Sternberg, 1985).
This connects to the wider context of fundamental theories of learning in modern classroom practice.
Intelligence is a well-studied idea in psychology. IQ tests used to measure logic and language skills. Now, research sees intelligence as complex.
Spearman and Gardner offer useful learning frameworks. We examine intelligence theories and classroom use.
IQ tests measure intelligence, focusing on logic, maths, and language. Critics say this is too narrow (Gardner, 1983). The tests might miss other key intelligences, especially for learners with special needs (Sternberg, 1985).
Multiple Intelligences Theory approaches" loading="lazy">Gardner (1983) said learners have varied intelligences. These intelligences show that learners process information in different ways. Teachers can view Gardner's (1983) ideas as one way to understand intelligence.
Cognitive skills include intelligence, and executive functions are key parts of them. We suggest a combined perspective helps teachers understand learners. This approach may help learners succeed.
Gardner's (1983) multiple intelligences theory offers other ways to think about intelligence. Sternberg's (1985) triarchic theory includes practical and creative intelligence. Together, these views give a more detailed picture than traditional IQ tests. Further research can benefit every learner.
Spearman's (date unspecified) g factor says a general ability (g) affects all thinking. Learners good at one cognitive test often do well on others. This suggests one underlying intelligence, Spearman believed. It underpinned traditional IQ tests.
Spearman (1904) said intelligence has two factors. The g-factor means general intelligence affects many areas. The s-factor shows specific intelligence (Spearman, 1904).

Spearman says the g-factor reflects overall intelligence. This intelligence affects a learner's performance in cognitive tasks. Learners use it to reason and solve problems (Spearman, 1904). It also helps them understand complex information.
Spearman (1904) suggested the s-factor alongside the g-factor. The s-factor means task-specific skills, such as talent in music or sports. This factor is separate from general intelligence. It shows more specialised abilities.
Spearman (1904) used factor analysis. This method explores how variables correlate. He tested intelligence scores from many learners. This revealed links with working memory.
Spearman (1904) saw test scores correlate. This suggested a general factor (g-factor) shapes abilities. This factor underlies verbal, maths and spatial skills for each learner.
Spearman (1904) suggested a two-factor theory of intelligence. The g-factor reflects general cognitive skills. The s-factor shows specific skills learners have (Spearman, 1904). Teachers can use this model to vary lessons.

Gardner (1983) originally identified seven intelligences, including linguistic and spatial; he later expanded the list to eight with naturalist intelligence in Intelligence Reframed (Gardner, 1999). Learners process information in diverse ways. Teachers can recognise strengths and adjust their teaching. Use it as a starting point for professional discussion: identify the learner's current need, record evidence from more than one lesson, and agree the next classroom adjustment with the SENCO or family.
Gardner (1983) changed how we see intelligence. He felt tests only on logic and language limit learners. Gardner (1999) said intelligence involves diverse skills.
Gardner found eight intelligences, showing varied ways learners think. Sternberg (1985) said intelligence has analytical, creative, and practical sides. Goleman (1995) popularised the concept of emotional intelligence, including empathy and self-regulation, but this should not be presented as proof of learner outcomes without a specific empirical education study. Teachers need these perspectives to help all learners succeed.
Gardner's (1983) theory matters for teaching. Learners have varied strengths, so teachers should change lessons. Kinesthetic learners benefit from hands-on tasks. Musical learners learn using songs (Gardner, 1983).
Howard Gardner's (1983) theory suggests teachers build inclusive learning spaces. This helps all learners succeed, no matter their strengths. Teachers can use multiple intelligences to deepen understanding. This approach also helps learners reach their full potential.
Sternberg (1985) defined intelligence as analytical, creative, and practical. Analytical intelligence helps learners solve problems, while creative intelligence helps them generate new ideas. Use it as a starting point for professional discussion: identify the learner's current need, record evidence from more than one lesson, and agree the next classroom adjustment with the SENCO or family.
Practical intelligence supports adaptation (Sternberg, 1985). Teachers can use this theory to develop learner abilities.
Sternberg (1985) said intelligence has three parts. Learners use analytical, creative, and practical skills. The theory explains how learners think (Sternberg, 1985). For related guidance, see our article on Growth Mindset.
Sternberg (1985) argues analytical intelligence aids learners to assess information with logic. Wechsler's WAIS-IV (2008) measures cognitive abilities through index scores such as Verbal Comprehension, Perceptual Reasoning, Working Memory, and Processing Speed, not simply verbal and maths skills. The tests check how learners solve problems.
Sternberg (1985) calls this creative intelligence, or the skill of making new ideas. It uses imagination and helps learners think in new ways (Guilford, 1967). This skill matters in art, new solutions, and innovation (Runco & Jaeger, 2012).
Sternberg (1985) said practical intelligence means adapting to real-world situations. Learners use common sense and apply what they know well. This helps learners succeed at work and in relationships (Sternberg & Hedlund, 2002).

Sternberg (1985) said all intelligences help learners succeed. Analytical intelligence helps learners with school tasks, while creative intelligence helps them solve issues (Sternberg, 1985).
Practical intelligence helps learners adjust to their world (Sternberg, 1985). Teachers must build every learner's intelligence.
Sternberg (1985) and Halpern (1996) found that solving problems builds learners' skills in analysis. Teachers can use debates, projects, and case studies to build critical thinking. These tasks help learners look closely at information.
Learners build creative intelligence when they make new ideas. Sternberg (1985) and Amabile (1996) say that brainstorming, role-play, and creative writing can help. Craft (2000) also found good results for learners.
Sternberg et al. (1995) found learners gain practical skills by applying knowledge. Real-world tasks like internships and projects help, say Sternberg et al. (1995). Simulations also improve learners' skills, as suggested by Sternberg et al. (1995).
Spearman, Gardner, and Sternberg offer different intelligence theories. These views help teachers see how learners take in and use information. By knowing these theories, teachers can better meet each learner’s needs (Spearman, n.d.; Gardner, 1983; Sternberg, 1985).
Teachers help learners reach their potential. Broader definitions of intelligence make learning more inclusive.
Learners thrive when teachers notice their diverse talents. Evaluations, not tests, best show a learner's intelligence (Gardner, 1983; Sternberg, 1985). Personalised learning matters.

Moran, Kornhaber & Gardner (2006)
Gardner and colleagues revisit multiple intelligences theory, arguing that the framework is best used to diversify how content is taught rather than to label learners. Teachers will
IQ tests often use language and logic to assess one general skill. Gardner (1983) proposed learners possess varied strengths, not just one. He identifies musical, spatial, or interpersonal skills beyond a single IQ score.
Teachers can practise this approach by providing varied tasks that allow learners to demonstrate their understanding in different ways. This might involve using visual aids for spatial learners or group discussions for those with strong interpersonal skills. By offering choice in how learners present their work, staff can help learners use their natural strengths to access the curriculum.
Researchers say general intelligence best predicts learner success. Gardner (various dates) argues talents are multiple intelligences. Despite criticism, his theory helps teachers spot varied learner strengths.
Frameworks help teachers see why some learners struggle on tests. This understanding improves differentiation and learner engagement. This method promotes inclusivity, valuing different learner successes.
One frequent error is labelling learners as having only one type of intelligence, which can limit their growth in other areas. Teachers should also avoid treating these theories as fixed traits, as cognitive abilities can change with the right support. It is important to use these frameworks as a guide for variety rather than a strict method for categorising children.

MI instruction helped learners achieve more than controls (Gardner, 1983). The study proves outcomes improved for learners when teaching matched varied intelligences. This supported underperforming learners (Yavich & Rotnitsky, 2020).
Gardner (1983) proposed multiple intelligences impact language learning. Researchers explore Gardner's (1983) theory in language acquisition. Maftoon and Najafi Sarem (2012) examine how multiple intelligences affect language learners and build on Gardner's (1999) own extension of the theory.
Maftoon & Najafi Sarem (2012)
This review links MI theory to language teaching. Activities like movement, music and group work help learners build vocabulary and fluency (Gardner, 1983). Teachers can adapt these lesson plans for subjects needing less text-based learning.
Multiple Intelligences (MI) theory suggests learners have varied strengths. Gardner (1983) proposed this framework with eight intelligences. Implementing MI can improve learner engagement and understanding.
Research by Gouws (2007) and Yavich and Rotnitsky (2020) supports MI in classrooms. Teachers can use MI to personalise learning for each learner.
Gouws (2007)
Gouws connects MI theory to outcomes-based learning. This structures lessons, balancing task types. Researchers saw improved learner engagement and fairer inclusion (Gouws).
Von Stumm, Chamorro-Premuzic and Furnham (2009) examined the role of personality and intelligence in self-estimates of cognitive abilities. They identified notable trends in how learners perceive their own intelligence.

The study by researchers shows intelligence self-belief varies across subjects and gender. This impacts learner confidence and choices (Cross & Griggs, 1990). Teachers can use this data to tackle fixed ability beliefs (Dweck, 2006). Support growth mindset in different cultures (Yeager & Dweck, 2012).
