In short, item analysis gives you a way to exercise additional quality control over your tests. Well-specified learning objectives and well-constructed items give you a headstart in that process, but item analyses can give you feedback on how successful you actually were. Item analyses can also help you diagnose why some items did not work especially well, and thus suggest ways to improve them for example, if you find distracters that attracted no one, try developing better ones.
Item analyses are intended to assess and improve the reliability of your tests. If test reliability is low, test validity will necessarily also be low. This is the ultimate reason you do item analyses—to improve the validity of a test by improving its reliability.
Higher reliability will not necessarily raise validity you can be more consistent in hitting the wrong target , but it is a prerequisite. That is, high reliability is necessary but not sufficient for high validity do you remember this point on Exam 1? However, when you examine the properties of each item, you will often discover how they may or may not actually have assessed the learning outcome you intended— which is a validity issue.
Take a deep breath. As a parent, the most important way you can help your child do well on tests is to read with your child regularly, talk with your child ren about their experiences, and provide regular routines while at home. When well-meaning parents focus too much on test results, they put undue pressure on young children. For kids who struggle with attention or memorization tasks, testing can be extremely stressful because it requires students to draw entirely on these skills.
Respond to any concerns your child has with encouragement and support. Emphasize that there are lots of ways to express what you know, and that these tests are just one measure. Mark testing days on your calendar to help remind you and your child ren when the testing will take place and plan your preparations. The student should eat a nutritious and filling breakfast. Set aside time each night prior to the test to review the concepts that will be covered if possible.
Try not to put too much pressure on the student. Reinforce that as long as they worked hard in preparation and did their absolute best you will be proud of them. Have the child ren visualize success. These worksamples are not like school or I. A high score on an aptitude worksample is an advantage in some jobs, but a disadvantage in others. The final step in the AIMS program is the presentation of test results and the interpretation of their significance.
During the conference, the meaning of each score and the significance of the overall pattern of aptitudes are explained. Occupations that match the aptitude pattern are presented.
When appropriate, colleges and college majors are recommended. Each examinee receives a copy of his scores, a report explaining the major recommendations, and a booklet that defines AIMS terminology. Also provided is a USB storage device that contains hundreds of pages of background materials and, when possible, a recording of the conference.
