four main domains of human development
Physical (body changes)
Personal (identity and personality changes)
Social (changes in relationships with others)
Cognitive (changes in thinking)
maturation and learning
Maturation: natural development largely guided by genes, but influenced by resources such as nutrition, teaching cannot push development beyond physical readiness
Learning: change through environmental interaction, active exploration, observing others, and guidance
nature vs nurture
Genes are expressed within environments; neither work alone
Development reflects heredity-environment interactions
The expression of inherited traits can vary across cultures and environments
principles of development
People develop at different rates, so age expectations are guidelines rather than fixed rules
Development is generally orderly and gradual, especially for physical abilities
But children may temporarily appear to regress when a skill isn’t fully secure
Piaget’s two basic tendencies
Organization: arranging thoughts and behaviours in schemas – mental frameworks for what to expect
Adaptation: adjusting schemas to fit the environment through assimilation and accommodation
assimilation, accommodation, equilibration, and disequilibrium
Assimilation: fitting new info into an existing schema
Accommodation: changing or creating a schema when info doesn’t fit
Equilibration: restoring balance when expectations match experience, using assimilation and accommodation
Disequilibrium: an uncomfortable mismatch between expectations and experience that prompts adjustment
main features of the pre-operational stage (ages 2-6/7)
Pretend play and symbolic thought (using language and numbers) emerge
Children often show egocentrism (difficulty taking another person’s perspective) and one-way logic -> can lead to failure on conservation tasks (ex: thinking a cut sandwich is more food than an uncut one)
concrete and formal operational stages
Concrete operational (about 7-11): understand conservation and reasons logically about concrete objects and events but may struggle with abstract ideas
Formal operational (about 11+): can reason abstractly about ideas, metaphors, identity, and social issues
adolescent egocentrism
A strong focus on one’s own thoughts, feelings, and concerns
The imaginary audience is the belief that others are constantly watching and evaluating you
These tendencies generally decline after early adolescence
Piaget’s educational implications and main criticisms
Teaching should match students’ developmental readiness, recognize individual differences, and let children actively engage with new info
Criticisms: abilities don’t always appear in neat stages, Piaget may underestimate children because tasks or instructions can be difficult, and his theory gives too little attention to social and cultural influences
what neo-Piagetians added to Piaget’s theory
They combine stage-related ideas with information-processing research and brain maturation
Executive functions – attention, working memory, planning, and problem solving – depend partly on the frontal/prefrontal cortex, which is among the last brain areas to mature
Vygotsky’s three central ideas
Cognitive development occurs in social and cultural contexts
Social interaction drives development
Language is a key tool mediating thought and interaction
co-construction
People build knowledge together through interaction, sharing perspectives, and jointly solving problems
Strategies learned socially can later be internalized
Cultural tools (ex: calculators or an abacus) support thinking and problem-solving
private speech development
Children first follow others’ instructions, then tell others what to do, and eventually talk themselves through tasks
Private speech becomes quieter and is internalized as inner speech, but may reappear as whispers or lip movements during difficult tasks
scaffolding, assisted learning, and the zone of proximal development (ZPD)
Scaffolding: support to guidance from a more knowledgeable person
Assisted learning: guided participation, with help gradually reduced as skill improves
ZPD: the gap between what a learner can do alone and what they can do with guidance, the goal is independent performance
Genie example from Vygotsky’s perspective
The case is used to illustrate how severe lack of early social interaction can disrupt cognitive and language development and how missed development windows may limit later learning
early maturing vs late maturing
Girls:
Early – sexual activity, school achievement, drug/alcohol use, depression, anxiety, eating disorders
Late – anxiety about development, fewer problems
Boys:
Early – social skills, popularity, risk-taking
Late – initial difficulties, creative, tolerant, perceptive
Issues:
Cultural differences, limited mixed results, challenges greater for gender non-conforming/non-binary youth
bronfenbrenner’s bioecological model
Microsystem: direct settings and relationships (family, school, peers)
Mesosystem: links between microsystems (ex: parent-teacher relationship)
Exosystem: setting that affect the child indirectly (ex: parent’s workplace)
Macrosystem: wider cultural and social values
Chronosystem: changes overtime and historical context
parenting styles
Authoritative: warm and supportive, with clear enforced rules; associated with stronger self-esteem and achievement
Authoritarian: strict “do as you’re told,” with little warmth; associated with lower self-esteem/self-control and more hostility
Permissive/indulgent: warm but few rules or limits; may contribute to impulsivity, immaturity, and self-centred behaviour
Rejecting/neglectful: low warmth and little guidance; associated with lower achievement, weaker relationships, aggression, risk-taking, insecurity, or withdrawal
attachment
A strong, enduring emotional bond between an infant and caregiver
Securely attached children explore, are comforted by the caregiver, and experience the world as more predictable
Secure attachment is associated with better school adjustment, independence, social interaction, and achievement
insecure attachment
Resistant: little exploration, clinging to caregiver, and strong distress
Disorganized/avoidant: few clear signs of attachment, muted emotions, or contradictory reactions
aggression
Instrumental: behaviour is to gain access to object/privilege
Hostile: intended to harm someone
Overt – physical (ex: hitting, kicking)
Relational – harms social relationships, such as exclusion or spreading rumours
Aggression can be learned from friends and media and can increase with frustration, hunger, stress, physical discomfort, or perceived unfairness
bullying
Grades 4-8:
86% have seen someone bullied
At least half have been bullied once
20% cyberbullied
Grades 7-8 – critical developmental age (bullying has a large impact on victim)
Relational bullying:
Targets social relationships (social exclusion, rumours)
Can be more damaging than overt + victims less likely to report (think it’ll make situation worse)
Can be difficult to detect (teasing common in friends)
Erikson’s theory of psychosocial development
Development involves 8 stages, each with a lasting psychosocial challenge or crisis
Each stage has 2 extremes, and healthy development generally lies between them rather than at either extreme
first 5 stages and their central questions
Trust vs. mistrust (birth – 1 ½): can I trust the world?
Autonomy vs. shame and doubt (1 ½ - 3): can I act independently and control myself?
Initiative vs. guilt (3-6): is it okay for me to explore and take initiative?
Industry vs. inferiority (6-12): am I competent? Peer relationships and skills become more important
Identity vs. role confusion (adolescence into early adulthood): who am I, and where am I going?
identity
Sense of self
Development more complicated if both dominant culture and one’s own culture are explored
Racial/ethnic pride -> better mental health, higher achievement, shorter moratorium
Marcia’s identity statuses
Diffusion: no commitment and little active exploration; everyone begins here
Moratorium: actively exploring actions but not yet decided
Foreclosure: commitment without much personal exploration; identity may be imposed by others and person can be rigid or dogmatic
Achievement: commitment made after exploring options; the person’s choices feel personally congruent
Remaining in diffusion is also possible, may be associated with an external locus of control (life is controlled by outside forces), apathy, susceptibility to peer pressure or isolation, and low self-esteem
difference between self-concept and self-esteem
Self-concept: what you believe or describe about yourself; can be general or domain-specific (ex: athletic)
Self-esteem: your emotional/evaluative response to that self-description; can also be general or domain-specific
Realistic high self-esteem can support achievement and well-being, while unrealistically high self-esteem may lead to defensiveness or aggression when challenged
what shapes students’ self-concept and self-esteem
School performance experiences, support when struggling, feedback from peers and teachers, and comparisons with others all contribute
During grades 7-8 and high school, self-concept, self-esteem, and self-efficacy may decline, while appearance becomes more important and is judged more critically
how peer groups change with age
Peer groups become more important around age 6, they develop norms for appearance, speech, behaviour, and interests
Cliques: small, close friendship groups with similar members; especially important in grades 6-9
Crowds: loosely organized categories (ex: jocks or nerds) based on stereotypes; especially important in early to mid-adolescence
intelligence
the ability to acquire and use knowledge
Spearman’s hierarchical model
General intelligence (g): an innate, single overarching factor that underlies all cognitive tasks and performance
Specific factors (s): narrow, unique skills tied strictly to individual, specific types of tasks (such as musical or mathematical proficiency)
Cattel-Horn-Carroll theory (CHC)
Three-strata hierarchy:
Stratum III: general intelligence
Stratum II: broad cognitive abilities (about 10-16 domains)
Stratum I: many narrow, specific abilities (about 70-80)
Cattell-Horn distinguishes fluid intelligence (processing and solving new problems; peaks in late adolescence) from crystallized intelligence (using acquired knowledge, can increase throughout life)
multiple intelligences: Gardner
1) Logical-mathematical: reasoning, numbers, patterns
2) Linguistic: language, reading, writing, storytelling
3) Visual-spatial: visualizing and manipulating objects mentally
4) Musical: rhythm, pitch, tone, melody
5) Bodily-kinesthetic: movement and coordination
6) Interpersonal: understanding other people
7) Intrapersonal: understanding oneself
8) Naturalistic: classifying living things and natural patterns
9) Existential: thinking about life, death, and meaning
issues/criticisms of Gardner’s theory
Benefits: it highlights varied abilities and encourages educators to look beyond one intelligence score
Criticisms: the abilities may be correlated, it is difficult to measure them reliably, and overly tailoring lessons to supposed “intelligences” may be unhelpful
Sternberg’s 3 types of intelligences
Analytic: formal problem-solving and analysis
Creative: adapting and dealing with novel problems
Practical: handling everyday problems
intelligence tests
The 1905 Binet-Simon test was an early practical standardized test designed to identify children needing extra educational help
It assessed mental processes, not just school knowledge
The Stanford-Binet followed in 1916; Wechsler tests followed (WAIS in 1939, WISC in 1949)
mental age and IQ
Mental age: the age group whose average performance matches the child’s test performance
Original IQ formula: (mental age / chronological age) x 100
how heredity impacts IQ scores
Clear heritable component – 50-80%
Interaction with environment – biological (nutrition, prenatal care), social/educational (school quality, SES, parental encouragement)
Reaction range – the genetically determined limits on IQ, while the environment determines where a person falls within that range
emotional intelligence (EI)
The ability to perceive emotions, use them to fit the task at hand, understand them, and manage them
Relevant to social and emotional learning (SEL)
creativity
Generating novel ideas or approaching a task in a new way
Draws on domain knowledge and skills, creativity-related processes and work habits, and intrinsic motivation or fascination with the area
difference between convergent and divergent thinking
Convergent: narrowing ideas to one answer, as in many conventional tests
Divergent: generating multiple possible ideas
Creative work often uses divergent thinking to generate options, then convergent thinking to organize and refine them
Torrence Test of Creative Thinking (TTCT)
Make as many different pictures as you can
Scores on:
1) fluency – number
2) flexibility – diversity
3) originality – commonality (an idea is deemed as original if it is generated by <10% of a normative peer group)
learning style and cognitive style
Cognitive style: ways of perceiving, organizing, and using info
Learning style: characteristic way of learning and studying
No credible evidence that matching instruction to preferred style improves learning outcomes
exceptional students and inclusion
Exceptional students perform outside the expected range, above or below it and may need specialized instructions
Inclusion places students in regular classes when appropriate, but doesn’t require full integration in every situation
Least restrictive placement means choosing the most enabling setting with needed supports
gifted and talented students
Giftedness may involve high competence, creativity, and sustained motivation, sometimes limited to one area
Can reflect early talent/interest and intensive practice
Some gifted students prefer older peers or adults, struggle to connect with same-age classmates, become frustrated when others learn more slowly, or experience existential concerns
Gifted adults may experience impatience, workplace alienation, underachievement, or burnout when insufficiently challenged or overly perfectionistic
how gifted students are identified and the possible emotional effects
Screening often occurs around grades 3-4
Methods include educational assessments, individual IQ tests, subject-specific tasks, creativity tests, and case studies
Being labelled as gifted can create performance pressure, perfectionism, or anxiety
acceleration vs enrichment for gifted students
Acceleration: learning the standard curriculum at a faster pace
Enrichment: adding deeper or more challenging work, sometimes through pullout programs with specialized teachers and academic peers
learning disabilities
Neurodevelopmental disorders that persistently and significantly affect learning or the use of academic skills
Difficulties may be specific (ex: reading/language or math) or involve organization, attention, behaviour coordination, memory, or social skills
They can persist across life so early intervention matters
working with students with learning disabilities
Direct instruction:
Clear, frequent explanation, instructions, guidance
Small steps, frequent practice
Frequent, immediate feedback
Peer support
Self-regulated learning
individual education plan (IEP)
A plan for each exceptional student, reviewed, and updated yearly, that includes:
Educational expectations (specific goals)
Special education programs/services provided
Progress monitoring methods
Transition plan, if appropriate
Responsibility: team approach, but the classroom teacher usually makes program-planning decisions and prepares the report card
Benefit of identification: access to additional resources
Concern: labels may cause stigma or self-fulfilling prophecies
early language development
Infants can initially distinguish sounds from many languages (2000 sounds)
Around 7-14 months, sensitivity to sounds not heard regularly declines, and perception becomes more specialized for the child’s native language
early language learning
Children have a biological predisposition to acquire language; two important supports are:
Joint attention: caregiver and child focus on the same object or action, helping the child connect words with meanings
Child-direct speech (“motherese”): speech with simpler structure and exaggerated, higher-pitched intonation; found across cultures
prespeech
Cooing (to about 3 months): vowel-like sounds such as “oo” and “ah”
Babbling (around 4-6 months): combines consonants and vowels, such as “ba-ba”
Around 7-11 months: sound repertoire narrows toward to the native language and speech-like intonation/jargon develops
approximate early language milestones
Around 10 months: responds to name, babbles, imitates simple sounds/gestures
12-18 months: first meaningful words and a small single-word vocab
18-24 months: around 50 words and two-word “telegraphic” phrases (ex: “want cookie”)
2-3 years: vocab grows to roughly 100-450 words and sentences often contain 3-4 words
3-5 years: longer stories, basic grammar, tenses, and rapidly growing vocab
Treat age ranges as guidelines, not rigid cutoffs
early language acquisition errors
Over-extension: using a word too broadly (calling all four-legged animals “doggie”)
Under-extension: using a word too narrowly (Using "dog” only for one familiar dog)
Overregularization: applying a regular grammar rule to an irregular form (saying “tooths” instead of “teeth”)
language skills during elementary school
Children improve pronunciation, use more complex syntax (ex: although and because), expand vocab through reading, understand nonliteral language (jokes, irony, sarcasm, metaphors), and learn abstract/academic words
pragmatics and metalinguistic awareness
Pragmatics: adapting language to the listener and social context; it is culturally specific and emerges early
Metalinguistic awareness: stepping back to analyze language itself, separate from its meaning; develops beyond age 5
influences on children’s reading development
Reading depends on decoding (linking speech sounds/phonemes to written letters/graphemes), oral language (vocab, grammar, story comprehension) and the home literacy environment
benefits of multiple languages
Improves cognitive abilities
Metalinguistic (easier to grasp grammar and build stronger reading/writing skills)
Easier time learning additional languages
what supports early bilingual development
Learn both languages before age 5
Exposure across varied settings and systematic, consistent, sustained input
A good-quality program may support everyday conversational language in 2-3 years and academic language in 6-9 years
profiles of language learners
Balanced bilinguals: L1 and L2
Monolingual/literate students: literate L1, limited proficiency in L2
Monolingual/preliterate students: limited/no literacy in L1, limited proficiency in L2
Limited bilingual students: converse well in both but trouble learning academically in both L1 and L2
heritage language and types of bilingualism
Heritage language: a home language that differs from the dominant societal language; may be lost by the third generation as families shift to dominant language
Additive bilingualism: learning a second language while maintaining the first
Subtractive bilingualism: learning a second language at the expense of the first
Balanced bilingualism: similar or near-equal proficiency in both languages
2 approaches to learning English
Immersion: instruction in English with max exposure; aims for rapid transition to English-only instruction
Most common but students may fall behind in core subjects (ex: math/science) and lose their first language
Native-language maintenance/bilingual learning: maintains and teaches the first language, transitioning to English when possible
Produces better outcomes but limited by funding, lack of bilingual teachers, and policies favouring English-only instruction
metacognition and its 3 main skills
Thinking about your own thinking
Planning: set goals and choose strategies, time, and resources before starting
Monitoring: check your understanding and progress during a task
Evaluating: reflect on the outcome and judge strategy effectiveness afterwards
3 types of metacognitive knowledge
Declarative (knowing what): knowing about yourself as a learner, the content, factors affecting performance, and available strategies
Procedural (knowing how): knowing how to perform a task or use a strategy
Self-regulatory (knowing when and why): knowing when and why to use a strategy in a particular situation
learning strategies and the 3 main types
Learning strategies are techniques for understanding, remembering, and applying information; they require effort, motivation, and self-regulation
cognitive - process info directly (ex: summarizing/organizing notes)
metacognitive - monitoring and regulate understanding (ex: checking comprehension)
behavioural - manage learning through actions (ex: setting timers)
effective learning strategies
PARS: preview, ask, read, summarize
Effective studying requires active processing, background knowledge, motivation, and self-regulation
Productive deficiency occurs when students know about effective strategies but fail to use them
problem solving
Means finding a solution when the path toward a goal is not obvious
Well-structured problems: have clear goals and procedures
Ill-structured problems: have ambiguous goals and multiple possible solutions
Three steps:
1) identify and represent: frame the problem, activate relevant schemas, and ignore irrelevant details
2) develop strategies: consider approaches such as breaking the problem into subgoals or working backwards
3) decide and evaluate: choose the most appropriate strategy based on effectiveness, experience, motivation, and risks
algorithm and heuristic
Algorithm: a precise, step-by-step procedure that guarantees a correct solution when applicable and followed correctly, but may be time-consuming
Heuristic: a mental shortcut or rule of thumb that saves time and effort but doesn’t guarantee a solution
cognitive biases that interfere with problem-solving
Functional fixedness: seeing an object only for its usual purpose, preventing alternative uses
Response set: getting stuck on one way of representing or solving a problem
Representativeness: judging likelihood by resemblance to a typical example or a typical example or stereotype while ignoring statistical probabilities
Availability: judging likelihood by how easily examples come to mind, potentially overestimating memorable events
Belief perseverance: maintaining a belief despite contradictory evidence
Confirmation bias: favouring evidence that supports existing beliefs while ignoring or dismissing contradictory evidence
critical thinking
Analyzing and evaluating info and your own reasoning to make clear, logic, evidence-based judgments
It involves questioning assumptions, assessing evidence, considering alternative explanations, and identifying weaknesses in arguments
transfer of learning
Occurs when knowledge, skills, strategies, or attitudes learned in one situation influence learning or performance in another
Positive transfer: previous learning helps new learning
Automatic (direct) transfer: a well-practiced skill is applied spontaneously, with little conscious thought
Thoughtful (preparatory) transfer: the learner deliberately recognizes an underlying principle or strategy and applied it to a new situation
Negative transfer: previous learning interferes because an earlier strategy or assumption is inappropriate
What impacts transfer:
Transfer is easiest between related domains when connections are direct and explicit
Transfer across unrelated domains requires recognizing abstract, conceptual similarities
Mastery, overlearning, deliberate strategy use, practice, feedback, and exposure to novel situations supports transfer
