1. Validity in Assessments: Content, Construct & Predictive Validity
Ensuring that an assessment measures what it is intended to measure is a critical component in education. Assessment results are used to predict future achievement and current knowledge. This lesson will define the term validity and differentiate between content, construct, and predictive validity.
2. The Reliability Coefficient and the Reliability of Assessments
How are test scores affected by day-to-day changes of a student? Do different people rate students' performances the same? These questions are addressed through the understanding of reliability. This lesson will define reliability, explain how reliability is measured, and explore methods to enhance reliability of assessments in the classroom.
3. Testing Bias, Cultural Bias & Language Differences in Assessments
Assessments are used to gain useful information about test-takers' knowledge, skills and progress. Sometimes, however, the results of these assessments are incorrect due to biases. This lesson will differentiate and discuss types of testing bias and differences among test-takers that may lead to testing bias.
4. Use and Misuse of Assessments in the Classroom
Assessments are excellent tools in the classroom. Used properly, they provide invaluable information about student knowledge and progress. However, if misused, assessments can misrepresent the actual knowledge and learning taking place in the classroom. This lesson will discuss the use and misuse of standardized assessments.
5. High-Stakes Testing: Accountability and Problems
Do high test scores equal high achievement? Many politicians and educational reformers think the answer is yes. High-stakes standardized testing has become commonplace in American schools. This lesson will define high-stakes testing and accountability and present problems associated with these types of tests.
