Remediation for a student whose unit/course averages or<br />

test grades fall below a predetermined grade.<br />

<br />

<br />

This method helps to identify students with potential<br />

problems before they experience a failure.<br />

These students should be placed in a less structured<br />

and less formal remediation environment than those<br />

assigned mandatory remediation due to test/objective<br />

failure. Once a student shows improvement, the<br />

requirement to attend remediation should be lifted.<br />

Test and Test Item Analysis. Test items and tests are prepared<br />

during development/revision of curriculum. During this time<br />

they are reviewed for content validity but in order to determine<br />

if they have statistical validity, test and test item analysis<br />

techniques are needed. The techniques used for analyzing test<br />

items include difficulty index, index of discriminating power,<br />

and effectiveness of alternatives. Each will be discussed in<br />

the paragraphs that follow.<br />

Procedures for Analyzing Test Items. While test item analysis<br />

procedures may vary between courses, the following general<br />

guidelines apply.<br />

<br />

<br />

Analyses are conducted from student answer sheets. The<br />

recommended sample size is 100. Smaller sample sizes will<br />

be necessary when class size and number of course<br />

iterations dictate. When the answer sheets have been<br />

collected, conduct the analysis manually or with computer<br />

assistance.<br />

Record the date items are analyzed to keep track of the<br />

performance of the test item over time. This information<br />

may be maintained manually on the test item bank or<br />

automatically with some computer programs. Historical data<br />

is used to study trends in order to make decisions about<br />

test items over time. For example:<br />

<br />

<br />

If the difficulty index of the test item suddenly<br />

changes, the testing personnel should investigate<br />

possible causes for the change.<br />

If a difficult item is now very easy, it may have been<br />

compromised. If an easy item suddenly becomes very<br />

difficult, this may mean instructors are not teaching<br />

effectively or the quality of the student has changed.<br />
