IN

General instructions

1. Objective/task of the question school be well difined. [1 Mark]

Answer:
1. Questions must clearly state the exact task expected from the student.
2. Ambiguity in framing questions should be completely avoided.

Teacher's Note:
a) Clear objectives ensure reliable assessment.
b) Vague wording causes confusion during evaluation.

2. Value points should be stated clearly in the marking scheme. [1 Mark]

Answer:
1. The marking scheme must detail specific breakdown of marks for every expected point.
2. This ensures consistency and objectivity among different evaluators.

Teacher's Note:
a) Explicit value points maintain uniformity in grading.
b) Examiners can award partial credit accurately.

3. If the expected answer is based on a diagram given in NCERT text book, its reference be given with fig no. and page no. [1 Mark]

Answer:
1. Questions referencing textbook illustrations must cite the specific figure and page number.
2. This helps both students and examiners locate the standard visual reference instantly.

Teacher's Note:
a) NCERT figures serve as standard benchmarks.
b) Providing citations eliminates ambiguity about the source diagram.

4. In numerical based questions emphasis should be given on scientific concepts rather than computational skills. [1 Mark]

Answer:
1. Numerical items should test the application of underlying scientific principles.
2. Lengthy or overly complex arithmetic calculations should be minimized.

Teacher's Note:
a) The goal is to evaluate physics or chemistry concepts.
b) Avoid turning science tests into mathematics computational drills.

5. Numerical problem should have all possible information required for the solution. For example, value of g, Avagrado number, atomic masses etc. should be mentioned. [1 Mark]

Answer:
1. Necessary physical constants must be supplied within the numerical problem itself.
2. Examples include acceleration due to gravity, Avogadro number, and standard atomic masses.

Teacher's Note:
a) Prevents student disadvantage due to memorization gaps.
b) Ensures uniform calculation results across all candidates.

6. The data given in the numerical problems should be practicable. [1 Mark]

Answer:
1. Numerical values assigned in problems must reflect realistic physical situations.
2. Unrealistic magnitudes or impossible physical conditions must be avoided.

Teacher's Note:
a) Realistic data fosters scientific intuition.
b) Absurd numbers undermine the credibility of the test item.

7. No question should be lifted directly from any help book. [1 Mark]

Answer:
1. Assessment items must be original or suitably modified.

2. Extraneous background information that does not test science should be omitted.

Teacher's Note:
a) Language should test science proficiency, not reading comprehension.
b) Simple phrasing reduces misinterpretation by students.

9. Multicoulured diagram for printing in question paper should be avoided. [1 Mark]

Answer:
1. Diagrams designed for the question paper should rely on line work rather than color.
2. This ensures clarity even when printed in black and white.

Teacher's Note:
a) Cost-effective and standard printing practice.
b) Prevents loss of information in monochrome photocopies.

10. Syllabus prescribed by CBSE should be followed strictly. However, for depth of the content, NCERT book may be considered as reference. [1 Mark]

2. The NCERT textbook serves as the definitive reference for depth and scope.

Teacher's Note:
a) Standardizes curriculum boundaries nationwide.
b) Prevents out-of-syllabus testing.

GUIEDELINES (SCIENCE PAPER)

VSA

1. Questions should be precise and pin pointed. [1 Mark]

1. Very Short Answer items must target a single, specific concept.
2. Broad or open-ended phrasing is unsuitable for VSA format.

Teacher's Note:
a) Focuses student response to exact requirements.
b) Facilitates rapid and objective grading.

2. Action verbs like define, explain, describe and discuss should be avoided. [1 Mark]

2. Questions should target direct identification or short recall.

Teacher's Note:
a) Long explanations belong to short or long answer categories.
b) Keeps answers strictly concise.

3. The anwer should not be of more than 2 value points. [1 Mark]

Answer:
1. Expected solutions for VSA questions must be restricted to a maximum of two distinct value points.
2. Keeps grading scale simple, typically 1 mark per point or 1 mark overall.

Teacher's Note:
a) Aligns with low weightage of VSA questions.
b) Prevents over-writing by students.

4. The answer should be of one word or one sentence. [1 Mark]

Answer:
1. The response format for VSA items must be extremely brief.
2. Answers must fit into a single word, term, or concise sentence.

Teacher's Note:
a) Tests direct recall and factual knowledge.
b) Saves examination time for candidates.

5. In diagram based questions instead of asking “to draw the diagram”, “to label” can be asked. [1 Mark]

Answer:
1. Testing drawing skills in VSA is impractical due to time and space constraints.
2. Questions should instead provide a printed outline for students to label specified parts.

Teacher's Note:
a) Efficient method to test structural knowledge in limited time.
b) Standardizes evaluation across diverse student drawing abilities.

MCQ

1. The questions should be strictly based on testing the skills required for doing practicals and these should not be theory based. [1 Mark]

Answer:
1. The guideline states that MCQ items must evaluate hands-on practical skills rather than pure theoretical knowledge.
2. This ensures experiential learning is assessed accurately.

Teacher's Note:
a) Focuses on practical competency assessment.
b) Avoid theoretical rote learning questions.

2. The questions should be such that it can be answered by only those students who have actually performed the practicals in schools. [1 Mark]

Answer:
1. Assessment items must validate actual laboratory experience.
2. Rote memorization of textbook theory should be insufficient to select the correct option.

Teacher's Note:
a) Promotes genuine laboratory participation.
b) Prevents guessing based on textbook reading alone.

3. All the four options should be relevent. [1 Mark]

Answer:
1. Every distractor must be plausible within the context of the practical procedure.
2. Absurd or obviously incorrect choices should be excluded to maintain assessment rigor.

Teacher's Note:
a) Distractors must represent common student misconceptions.
b) Implausible options reduce the discrimination index of the item.

4. Options like 'all the above' and 'none o the above' should be avoided. [1 Mark]

Answer:
1. Avoid lazy phrasing that encourages test-taking tricks over conceptual understanding.
2. Each option must present a distinct substantive statement.

Teacher's Note:
a) Eliminates cueing effects in multiple choice items.
b) Tests specific knowledge rather than elimination strategies.
