Study Notes
Biological Beginnings
- Human characteristics are influenced by genetic instructions present at birth and developing physical features.
- Sensitive periods are age ranges where environmental experiences are crucial for development.
- Canalized skills, such as motor skills, are controlled by genetics, while non-canalized skills, such as reading, are heavily influenced by the environment.
- Genetic predispositions can be altered by environmental factors like schooling, social interactions, and physical experiences.
- The human genome, the complete set of developmental instructions for creating proteins, has been mapped.
- Genes interact with each other and non-genetic factors both inside and outside the body.
- Internal and external events influence whether genes are "turned on" or "off," with examples including stress and exercise.
- Dominant genes override the expression of recessive genes.
- Recessive genes exert their influence only if both genes in a pair are recessive.
- Sex-linked genes are carried on the X chromosome.
- Females are carriers while males may exhibit X-linked diseases.
- Genomic imprinting occurs when genes have different effects depending on whether they are inherited from the mother or father.
- A chemical process "silences" one member of the gene pair.
- Most human characteristics are determined by the interaction of several genes.
- Gene-gene interaction refers to the interdependence of two or more genes in influencing traits, behavior, diseases, and development.
Teratology and Hazards to Prenatal Development
- Teratogens are agents that cause birth defects.
- Drug use during pregnancy is associated with various complications like low birth weight, placenta previa, preterm delivery, fetal growth restriction, and sudden infant death syndrome.
- Prescribed medications can have serious teratogenic effects.
- Heavy marijuana use is linked to brain damage and mothers addicted to heroin often pass the addiction to their child.
- Exposure to radiation during the first trimester of pregnancy increases the risk of congenital deformities, miscarriage, and stillbirth.
- Exposure to mercury can lead to physical deformities and mental retardation.
- HIV is a potentially devastating teratogen.
- Measures to reduce the risk of transmission include avoiding breastfeeding and delivering the child via Cesarean section.
Neuroscience and Brain Development
- Technological advancements in neuroscience have enabled research into the human brain, particularly during the first six years of development.
- This period is characterized by greater plasticity, the brain's ability to change through new connections between neurons formed by experiences and learning.
- Neuroplasticity modifies the physical structure, chemicals, and function of the brain through interactions with the environment.
- From birth, the brain develops rapidly, leading to neuro-psychomotor development, including movements of the head, limbs, and hands.
- Environmental interactions contribute to the child's ability to handle objects and develop speech, forming new synaptic connections that support learning and skill acquisition.
- By age two, children can move freely, gain physical strength, socialize, and differentiate objects.
- This stage presents opportunities for stimulating physical, manual, and social skills through recreational activities and sensory experiences.
- Three-year-old children develop fine motor skills like drawing, reading, and dressing.
- Parents can encourage autonomy and self-care by fostering organization and hygiene habits.
- Between four and six years of age, children engage in make-believe and social play.
- This stage is ideal for developing social skills like empathy, cooperation, trust, solidarity, and respect for others.
Factors Affecting Biological and Physical Development
- The environment plays a crucial role in influencing biological and physical development.
- Nutrition is essential for growth and development.
- Poverty can have a negative impact on growth due to limited access to nutritious food, healthcare, and education.
- Stress can interfere with development and contribute to health problems.
- Exposure to toxins, such as lead, can have detrimental effects on various systems.
Current Research and Pedagogical Applications
- Pedagogy is the theory and practice of learning, focusing on how knowledge and skills are imparted in educational settings.
- Pedagogical content knowledge (PCK) integrates subject content knowledge and pedagogy.
- PCK emphasizes the interpretation and transformation of subject knowledge to facilitate student learning.
- Subject matter knowledge extends beyond simply knowing a lot about a topic. It involves thinking in a disciplined manner that can be applied broadly.
- PCK illustrates how subject matter is transformed for communication with learners. It involves understanding the difficulties students experience with specific concepts, their prior knowledge, and tailoring teaching strategies accordingly.
- The curriculum's purpose is to facilitate effective student learning, encompassing more than just guiding them through specific chapters in subjects like math, science, or literature.
- The curriculum reflects national cultural expectations and the educational context in which it is implemented.
- Teachers need to understand subject matter deeply and flexibly to help students connect ideas, generate new insights, and direct their thinking for powerful learning experiences.
- Students should have ample opportunities to achieve learning outcomes and develop essential knowledge, skills, and understandings.
- Social and emotional development is crucial for children's well-being and success in life.
- Early childhood is a critical period for developing self-awareness, empathy, social skills, and self-regulation.
- Piaget emphasized that middle childhood is a time when children become less egocentric and more responsive to the perspectives of others.
- Adolescence requires the development of expanded verbal skills.
