Validity and reliability

Chapter 3 of our textbook discusses several important aspects of standardized testing. One idea is the importance of reliability and validity in standardized tests. For this post, watch the following videos on test validity and reliability. 
Introduction to Test Validity
ReliabilityThen, imagine that your center or school is looking for an assessment instrument to measure reading ability. The selection has been narrowed to two possibilities: Test A shows measures of strong validity, but there is no information about its reliability; Test B includes measures of strong reliability, but there is no information about its validity. Which test would you recommend? Be sure to include at least three specific reasons as to why you chose the test you did.
Guided Response: Read several of your classmates’ posts and respond to at least two of your peers. As you respond to your classmates, discuss whether you agree or disagree with the test they recommended. Justify your point of view by providing at least two reasons for why you agree or disagree. Also, include examples of how they could increase the validity or reliability of the test they chose.
