Question 8

Both NCF 2005 and NEP 2020 advocate for reforms in assessment practices. A significant shift proposed by NEP 2020, building upon NCF 2005's recommendations, is the move towards:

Accepted Answer

C. Holistic, competency-based assessment that promotes learning and development. — Both NCF 2005 and NEP 2020 emphasize moving away from rote learning and towards assessments that are holistic, competency-based, and promote learning rather than just testing recall. NEP 2020 further strengthens this by proposing reforms like PARAKH. Options A and D represent practices that both frameworks aim to reduce or reform, while B is specific to higher education admissions, not the general principle of school assessment reform.

Answer

A. Increased reliance on summative assessments at the end of academic years.

Answer

B. Standardized entrance exams for all higher education admissions nationwide.

Answer

D. Mandatory board exams for grades 5 and 8 to ensure basic learning outcomes.

Question 10

During a psychological assessment, a candidate is presented with several novel, ill-defined problems and asked to generate innovative and imaginative solutions, rather than recalling established facts or following predefined algorithms. According to Robert Sternberg's Triarchic Theory of Intelligence, which component of intelligence is primarily being assessed in this scenario?

Accepted Answer

B. Experiential Intelligence — Sternberg's Experiential Intelligence (also known as creative intelligence) deals with an individual's ability to cope with novel situations and to generate new ideas. The assessment focuses on generating innovative solutions to ill-defined problems, which directly aligns with the definition of experiential intelligence. Componential intelligence involves analytical thinking and problem-solving using existing knowledge, while contextual intelligence relates to practical application in real-world environments.

Answer

A. Componential Intelligence

Answer

C. Contextual Intelligence

Answer

D. Emotional Intelligence
