Assessments

Assessment activities are used to decipher how much students learn under certain time frames.  These assessment provide information to teachers as to whether their students are meeting state set, district and teacher set standards.  By using different types of assessment strategies, summaries and reflections, graphic organizers, and collaborative activities, teachers can keep track of specific data that can improve learner performance and proficiency.
E-portfolio's are digital portfolios assembled by individuals as a collection of evidence of works that they have created. They provide access to teachers and students to materials for use in planning and research.
Computer based tests are tests administered on a computer and the results are electronically recorded.  Their use can impact validity and reliability due to the consistency on which the same results are recorded and whether or not the answer is reliable.  The validity of such testing could be based upon common opinion.
Teachers ands students will always benefit from assessments due to the results showing areas in which improvement is needed.  The use of E-portfolio's will benefit both students and teachers by being able to access their own created accounts and the sharing to other information.  Computer based testing will also provide teachers and other access to shared data.
