TET Practice Set 1

Explanation: Adolescence (approximately 12-19 years) is marked by rapid physical growth (puberty), hormonal changes, identity formation (Erikson's identity vs. role confusion), emotional turbulence, and the search for self-identity.

Explanation: The nature-nurture debate examines the relative influence of heredity (biological/genetic factors — nature) and environment (experiences, culture, upbringing — nurture) on human development. Modern psychology recognises that both interact continuously.

Explanation: Vygotsky's sociocultural theory posits that cognitive development is fundamentally shaped by social interaction and cultural tools (especially language). He argued that higher mental functions develop first on the social plane before being internalised.

Explanation: At the post-conventional level (stages 5-6), moral reasoning is based on self-chosen ethical principles and universal human rights that may transcend specific laws. The individual recognises that laws are social contracts that can be changed if unjust.

Explanation: Dyslexia is a specific learning disability characterised by persistent difficulty with reading, including problems with word recognition, decoding, and spelling. It is not related to intelligence — dyslexic children can be highly intelligent.

Explanation: Activity-based learning engages children through hands-on activities, making abstract concepts concrete and understandable. When children do, explore, and manipulate, they construct deeper understanding and retain knowledge better than through passive listening.

Explanation: NEP 2020 replaces the 10+2 structure with a 5+3+3+4 design: Foundational (ages 3-8), Preparatory (8-11), Middle (11-14), and Secondary (14-18). This recognises the importance of early childhood education and provides greater flexibility.

Explanation: Maslow's hierarchy of needs places physiological needs (food, water, shelter, sleep) at the base. These must be adequately met before higher-level needs (safety, belonging, esteem, self-actualisation) can be addressed. A hungry child cannot focus on learning.

Explanation: The Socratic method involves teaching through questioning rather than direct instruction. By asking a series of probing questions, the teacher guides students to examine their assumptions, think critically, and arrive at understanding through their own reasoning.

Explanation: Bhasha Arjan (language acquisition) refers to the natural, subconscious process through which children develop their first language through exposure and interaction, without formal instruction — as opposed to Bhasha Adhigam (language learning), which is conscious and formal.

Explanation: A portfolio combines samples of work collected over time — writing samples, recorded speaking, reading logs, project work — giving a comprehensive picture of a student's language development. It assesses process and growth, not just a single test performance.

Explanation: Communicative Language Teaching focuses on developing communicative competence — the ability to use language effectively in real-life situations. It prioritises fluency and meaningful interaction over accuracy and grammar drills.

Explanation: L2 acquisition occurs after the critical period for L1, so it is influenced by the learner's first language (transfer effects), involves more conscious effort, and is affected by factors like motivation, anxiety, and exposure that play a lesser role in L1 acquisition.

Explanation: In the number 37,265, the digit 7 is in the thousands place. So its place value is 7 x 1000 = 7,000.

Explanation: In a proportion, the product of extremes equals the product of means. So 3 x 35 = 5 x x, giving 105 = 5x, so x = 21.

Explanation: Circumference of a circle = 2 x pi x r = 2 x (22/7) x 14 = 2 x 22 x 2 = 88 cm.

Explanation: The heuristic approach (from the Greek 'heuriskein' = to find) encourages students to discover mathematical truths for themselves through exploration and problem-solving, rather than being told. The teacher acts as a guide, not a transmitter of knowledge.

Explanation: Mean (average) = Sum of observations / Number of observations = (1 + 2 + 3 + 4 + 5) / 5 = 15 / 5 = 3.

Explanation: A balanced diet contains all essential nutrients (carbohydrates, proteins, fats, vitamins, minerals, and water) in the right proportions needed for proper growth, development, and maintenance of the body.

Explanation: Amphibians are animals that can live both in water and on land. Examples include frogs, toads, salamanders, and newts. They typically begin life in water (as tadpoles) and later develop the ability to live on land.

Explanation: EVS at the primary level helps children connect their learning with their immediate environment, developing environmental awareness, scientific temper, and social sensitivity through direct observation and exploration of their surroundings.

Explanation: Xerophytes are plants adapted to survive in arid environments. Succulents, a type of xerophyte, have thick fleshy stems and leaves that store water. Examples include cacti and aloe vera. They also have deep roots and often have thorns instead of leaves.

Explanation: Photosynthesis is the process by which green plants use chlorophyll to capture sunlight energy and convert carbon dioxide and water into glucose (food) and oxygen. The equation is: 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.

Explanation: In a physical change, the appearance, size, or state of matter may change, but the chemical composition (the substance itself) remains the same. Examples: melting of ice, dissolving sugar, tearing paper. The change is usually reversible.

Explanation: Sound requires a material medium (solid, liquid, or gas) to travel because it propagates as mechanical waves through the vibration of particles. A vacuum contains no particles, so sound cannot propagate through it.

Explanation: The Revolt of 1857 (First War of Indian Independence) began at Meerut on 10 May 1857, when Indian sepoys rose against British officers. It quickly spread to Delhi, Kanpur, Lucknow, Jhansi, and other parts of northern India.

Explanation: Mars is known as the 'Red Planet' because its surface contains iron oxide (rust), which gives it a distinctive reddish appearance when viewed from Earth. It is the fourth planet from the Sun.

Explanation: The Preamble begins with 'We, the people of India', signifying that the Constitution derives its authority from the people of India. It declares India to be a sovereign, socialist, secular, democratic republic.

Explanation: Inquiry-based learning in social science trains students to ask meaningful questions about society, investigate evidence from multiple sources, evaluate arguments critically, and construct well-reasoned conclusions — skills essential for democratic citizenship.

Explanation: In Piaget's theory, a schema is a mental framework or pattern of thought that organises and interprets information. As children encounter new experiences, they either assimilate them into existing schemas or modify (accommodate) their schemas to fit new information.
