Why a vocabulary lesson?

'My teacher said the school has tough new standards and I need to improve my vocabulary. What's 'vocabulary'?'

Establish a common languageClear understanding by all

Better communicationAbout processesAbout resultsAbout student achievement/failureAbout instructional practices that yield learning

Two Major Types of Tests

Norm-Referenced Test (NRT)

Criterion-Referenced Test (CRT)

What is a Norm-Referenced Test (NRT)?

• A standardized assessment in which all students perform under the same conditions.

• It compares the performance of a student or group of students to a national sample of students at the same grade and age, called the norm group.

What is a Criterion-Referenced Test (CRT)?

•An assessment where a student's performance is compared to a specific learning objective or performance standard and not to the performance of other students.

•It tells us how well students are performing on specific goals or content standards rather than just telling how their performance compares to a norm group of students nationally or locally.

Question:

In criterion-referenced assessments, is it possible that none, or all, of the students will reach a particular goal or performance standard?

Answer:

YES!!!

Three Major Types of Scores

Raw Score (RS)

• The number of items a student answers correctly on a test.– John took a 20 item

mathematics test (where each item was worth one point) and correctly answered 17 items.

– His raw score for this assessment is 17.

Question:

If Mary answered 24 items correctly on a reading test, and 40 items correctly on a mathematics test, did she do better on the mathematics test than on the reading measure?

Scale Score (SS)

• Mathematically converted raw scores that use a new, arbitrarily chosen scale to represent levels of achievement or ability. They have no inherent or readily apparent meaning.

• For FCAT-SSS, a computer program is used to analyze student responses and to compute the scale score. It reports test results on the student’s entire test.

Scale Score (SS)

• Higher scale scores indicate higher proficiency.

• On a continuous, vertical scale across grade levels you can track a student’s progress from lower to upper grade levels on one scale. Growth in scale score units indicates growth in proficiency.

• For FCAT-SSS, the Developmental Scale Score is used to determine a student’s annual progress from grade to grade.

Gain Scores

• Commonly referred to as “Learning Gains”.

• The amount of progress a student makes in one school year.
