Formative Assessment

• Primary Purpose Feedback.• Brings Out Strength And Weakness Of

Student.• Should Happen As Often As Possible.

• Should Not Be Used For Final Certification.• Need Not Be Graded..

Summative Assessment

Purposes.

• Assessment Is Summative If Results Are Going To Be Used To Make Educational Decisions.

Self Assessment

– What He Or She Believes Is Important To

Assess.

Effective;

i. Should Not Be Completely Self Selected.

• Qualities of a Good Assessment?

Qualities of Good Assessment

1. Validity.

2. Reliability.

3. Acceptability.

4. Consequences Of Assessment.

Van der Vleuten & Schuwirth (2005)

Validity

• Measuring What It Intend To

Measure.

• Interpretation That We Make Out Of

Assessment Data.

• Does Not Refer To The Tool Or Result.

• Degree To Which A Test Measures What It Purports (Apparently Appears) To Measure.

Extent To Which Certain Inferences Can Be Made From Test Scores, Difficult To

Quantitate, Qualitative Measurement From Different Sources.

Content Validity..?

Does It Include (All) The Right Items?

Physiology Medicine

• How Can We Build A Validity?

• Assessment Should Match The Contents Of The Course.

• Provide Proportional Weightage To Each Of The Contents.

• Table Of Specification (TOS).• Faculty Training.• Screening of Items.

• Let The Student Know What Is Expected!!!

• Neither Too Difficult Nor Too Easy.• Appropriate Wording To The Level Of

Students.

Reliability

• Reproducibility of the score.• Getting the same result under the

same condition.• Test – retest• Equivalent form• Scorer / rater

Reliability Degree To Which A Test Is Consistent And Reproducible.

Measure Of How Stable, Dependable, Trustworthy, And Consistent A Test Is In Measuring The Same Thing Each Time.

• To Be Valid, A Test Has To Be Reliable.

• Reliability Is Precondition For Validity.

• Objective vs Subjective Assessment…

Objective Assessment• Have one or more

clearly correct or incorrect responses.– MCQs.

Subjective Assessment

• Require judgments about a response.– SEQs.
