REET Practice Set 1

Explanation: Egocentrism is a hallmark of the pre-operational stage, where children have difficulty seeing things from perspectives other than their own. They assume everyone sees, feels, and thinks the same way they do.

Explanation: B.F. Skinner proposed the theory of operant conditioning, which states that behaviour is shaped by its consequences — reinforcement (positive or negative) strengthens behaviour, while punishment weakens it.

Explanation: Blood group has no known effect on cognitive learning. Attention, interest, and aptitude are well-established factors that significantly influence the learning process. Motivated, interested learners with relevant aptitude learn more effectively.

Explanation: Projection is the defence mechanism where individuals unconsciously attribute their own unacceptable thoughts, feelings, or impulses to others. For example, a dishonest person accusing others of being dishonest. Freud identified this as a key ego defence.

Explanation: Action research is a reflective process conducted by practitioners (teachers) in their own classrooms to solve specific practical problems and improve their teaching practice. It is not formal academic research but a tool for professional development.

Explanation: The RTE Act 2009 specifies that the pupil-teacher ratio should not exceed 30:1 for primary classes and 35:1 for upper primary classes. This ensures adequate individual attention for every child.

Explanation: Emotional intelligence (EI), popularised by Daniel Goleman, refers to the ability to recognise, understand, manage, and effectively use one's own emotions and those of others. It includes self-awareness, empathy, and social skills.

Explanation: Listening is the foundational language skill — it is the first skill children develop naturally and forms the basis for speaking, reading, and writing. Good listening comprehension is essential for effective communication and learning.

Explanation: A chemistry laboratory is a science-specific facility, not a teaching aid for Hindi language instruction. Flash cards, story books, and audio recordings are all effective aids for teaching Hindi at the primary level.

Explanation: In rural Rajasthan, limited exposure to English outside the classroom is a major challenge. Students rarely encounter English in daily life — at home, in markets, or in media — making it difficult to practise and reinforce what is taught in school.

Explanation: Comprehensive language evaluation must assess all four skills — listening, speaking, reading, and writing — through diverse modes such as oral tests, written tasks, portfolios, and observation. Relying on one mode gives an incomplete picture.

Explanation: 3/4 is a rational number (can be expressed as p/q where q is not zero) but it is not an integer. The numbers -5, 0, and 7 are all integers (and also rational numbers, since they can be expressed as -5/1, 0/1, and 7/1).

Explanation: When all three pairs of corresponding sides of two triangles are equal, the triangles are congruent by the SSS (Side-Side-Side) criterion. This is one of the five congruence criteria (SSS, SAS, ASA, AAS, RHS).

Explanation: A cube has 6 identical square faces. Surface area = 6 x (side)^2 = 6 x 5 x 5 = 6 x 25 = 150 sq. cm.

Explanation: Error analysis is a diagnostic technique where teachers systematically study the types and patterns of mistakes students make to identify underlying misconceptions. This allows for targeted remedial instruction that addresses root causes rather than surface errors.

Explanation: The Thar Desert receives less than 25 cm (250 mm) of average annual rainfall, making it one of the driest regions in India. This scarcity of water has led to the development of traditional water conservation systems like tankas, johads, and nadis in Rajasthan.

Explanation: The Camel (Camelus dromedarius) is the state animal of Rajasthan. Also known as the 'Ship of the Desert', the dromedary camel is perfectly adapted to the arid conditions of the Thar Desert and has been integral to Rajasthani culture and economy.

Explanation: A Tanka is a traditional underground rainwater storage tank built primarily in the Thar Desert region. It collects and stores rainwater that runs off rooftops and paved courtyards, providing drinking water during the dry months. It is a remarkable example of indigenous water harvesting.

Explanation: Effective EVS teaching should connect with the child's immediate environment and lived experiences. In Rajasthan, this means using the local desert ecosystem, water scarcity issues, traditional practices, and local biodiversity as starting points for exploration and learning.

Explanation: Mitochondria are called the 'powerhouse of the cell' because they produce ATP (adenosine triphosphate) through cellular respiration. ATP is the energy currency used by cells for various life processes.

Explanation: Newton's First Law (Law of Inertia) states that an object at rest stays at rest and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced external force.

Explanation: Coal is a non-renewable (fossil) energy source that takes millions of years to form and exists in finite quantities. Solar energy, wind energy, and biomass are renewable sources that can be replenished naturally in a human lifetime.

Explanation: Jerome Bruner advocated the discovery method of learning, where students discover facts, principles, and relationships on their own through guided exploration rather than being told directly. He believed this leads to deeper understanding and better retention.

Explanation: The Hawa Mahal (Palace of Winds) was built in 1799 by Maharaja Sawai Pratap Singh of the Kachwaha Rajput dynasty. It was designed by Lal Chand Ustad in the form of the crown of Lord Krishna and has 953 small windows (jharokhas).

Explanation: The Aravalli Range runs from southwest to northeast across Rajasthan, dividing it into two distinct regions: the Thar Desert (arid western region) to its northwest and the relatively fertile eastern plains (semi-arid) to its southeast.

Explanation: Rajasthan was the first state in India to introduce Panchayati Raj, which was inaugurated by the then Prime Minister Jawaharlal Nehru on 2 October 1959 at Nagaur. This was based on the recommendations of the Balwant Rai Mehta Committee.

Explanation: The survey method involves students collecting data from people in their community about social issues. It develops research skills, connects classroom learning with real-world issues, and promotes critical analysis of social phenomena.

Explanation: Growth refers to quantitative, measurable changes in the body such as increases in height, weight, and size. Development, on the other hand, refers to qualitative changes in functioning and capability. Growth is one aspect of the broader process of development.

Explanation: Intrinsic motivation comes from within — driven by personal interest, curiosity, or the satisfaction of the activity itself. Extrinsic motivation comes from external factors like rewards, grades, or praise. Research shows intrinsic motivation leads to deeper and more sustained learning.

Explanation: Inclusive education requires adapting the school environment, curriculum, and teaching methods to accommodate all learners, including those with disabilities. This includes barrier-free access, trained teachers, assistive devices, and a supportive classroom culture.
