In Module 6 you will learn about

Test blueprints…what they are and why you need them

The components of a test blueprint Criteria for a good test blueprint Test blueprint example

“If you don't know where you're going, any road will take you there.”

George Harrison (1943 - 2001)"Any Road", Brainwashed, 2002

Wherever “there” is…? No destination in mind?

Not only will any road get you there…

But you will have no way of knowing that you have even arrived!

Assessment with a Purpose

Educational assessment is not something incidental to teaching and learning. It is an equal partner with curriculum and instruction. It is the critical “3rd leg” through which both students and teachers receive feedback about the effectiveness of the teaching and learning process in achieving desired learning outcomes. Assessment closes the loop.

Purposeful Assessment Requires thoughtful alignment –

ensuring that the items on a test fairly represent the… Intended (curriculum) and actual

(instructional) learning targets Relative importance of those targets Level of cognitive complexity associated

with those targets

Useful Feedback Also requires tests that are…

Reliable (consistent; actually measure something)

Fair (Free from bias or distortions) Valid (contextually meaningful or interpretable;

can reasonably support the decisions we make based on them)

Test Blueprints, Big Picture Are a simple but essential tool test

developers use to design tests that can meet the preceding requirements

Define the acceptable evidence to infer mastery of the targets

Test Blueprints, Details Explicitly “map” test items to: Learning Targets Levels of Complexity Importance

Decision-making without data…

is just guessing.

GLCEs and HSCEs

Taxonomies

For Cognitive Complexity

Bloom’s Cognitive DomainUnderstanding by Design (Wiggins, McTighe)Depth of Knowledge (Norm Webb)

Bloom Level 1 Level 2 Level 3 Level 4 Level 5 Level 6

UbD Level 1 Level 2 Level 3 Level 4 Level 5

DOK Level 1 Level 2 Level 3 Level 4

Putting it all together…A Basic Test Blueprint Table (matrix) format (spreadsheet) Rows = learning targets (one for each

GLCE, HSCE, etc.) Columns = levels of cognitive

complexity (one column for each level to match the taxonomy you chose to use)

Cells = number of items and points possible

Summary Information

Number of items and points possible:

Row Margins = for that target

Column Margins = for that level of complexity

Lower Right Corner = for the test

Basic Example5 Targets, 3 Levels (DOK)LearningTargets

Level 1# (pts)

Level 2# (pts)

Level 3# (pts)

Target Totals# (pts)

Target 1 3 (3) 2 (2) 5 (5)

Target 2 1 (1) 2 (2) 2 (4) 5 (7)

Target 3 2 (2) 1 (3) 3 (5)

Target 4 3 (3) 1 (2) 4 (5)

Target 5 2 (4) 1 (4) 3 (8)

Level Totals# (pts) 6 (6) 10 (14) 4 (10) 20 (30)

Is this reasonable?Rule of Thumb Criteria… At least 3 items per target (5 is better) for

reliability Appropriate distribution of items over targets

(1 & 2 appear to be more important than 3 & 5) Levels of complexity are appropriate for targets

and instruction Appropriate distribution of items over levels of

complexity(all items are NOT at the lowest or highest level)

Limitations… Shows total points for each target/level

combination, but not how those points apply to each item

Doesn’t show item types Doesn’t indicate if partial credit scoring

can/will be used (but may be implied) But…it was easy to construct, is still a

useful blueprint, and is much better than not making one!

Some added sophistication…

It is also useful to keep track of item types / formats to ensure: Appropriate match to learning targets

and associated levels of complexity Balanced use within tests and across

tests over time Track on same or separate spreadsheet

Common item types include… Selected-response (multiple-choice)

(Module 7) Constructed-response

Brief (fill-in-the-blank, short answer, etc.) Extended (outline, essay, etc.) (Module 9)

Performance (Module 8)

Other item types include…

Matching Sort/arrange a list in order Projects

Complexity vs. Utility Your test blueprint could get complicated

if you try to account for too much in one spreadsheet.

Make sure your test blueprint covers the basics, is not a burden to create, and is useful to you

The following example is slightly more sophisticated, but still workable
