“Validity is the extent to which a test measures what we actually wish to measure” (Cooper and Schindler, 2014, p.257). “Reliability has to do with the accuracy and precision of a measurement procedure” (Cooper and Schindler, 2014, p. 257). Validity is more critical to measurement than reliability because without validity, reliability is meaningless. For example, a bathroom scale may give a weight each time a person weighs themselves, which proves the scale is reliable in giving feedback. If the scale displays an incorrect weight each time then it is not a valid weight and a person cannot accurately measure themselves to know if a goal is being met or not. Validity and reliability can also be thought of in terms of a person and their work. A person may show up to work on time and complete all tasks that are required everyday, which proves they are reliable, however if they tasks are not completed correctly then there is no validity to work and it must be redone. Finally, validity…
Reliability can be explained as the consistency of scores over time. Assessments are usually reliable when you get the same results regardless of when the assessment is taken or who does the scoring. On the other hand, Validity indicates how well an assessment actually measures what it is supposed to measure. Every assessment requires students to complete some task or activity and the validity of the task should reflect some knowledge or performance, and be consistent with current educational theory and practice. The quality of the assessment should be reliable because you would think that teachers thought carefully about the assessment before giving it to their students.…
In order to prepare effective assessments we need to think about the key concepts and principles. It starts with validity. We need to make sure learners understand what we are actually assessing or measuring. For example are we assessing learners’ writing and reading skills when it is an assessment in Maths. Assessments are only valid if it evaluates what it is actually aimed to evaluate. Reliability is another concept that is related to validity but the importance is more on the accuracy and consistency of its purpose. Would we get the same outcome if we set the assessment up at a different time and different place with the same group of learners? Reliability is mostly based on all the assessors using the same standards and marking schemes.…
3) How do you feel about these types of scores being used to compare you with another person? Please explain?…
For a classification system to be meaningful and useful, it needs to be valid and reliable. Reliability refers to the consistency of a measuring instrument, such as a questionnaire or scale to assess, for example, the severity of their schizophrenic symptoms. Reliability of such questionnaires or scales can be measured in terms of whether two independent clinicians give similar diagnoses (this is known as inter-rate reliability) or whether the diagnoses are consistent over time (this is known as test-retest reliability).…
Standardization is defined as the process by which test constructors ensure that testing procedures, instructions, and scoring are identical, or as nearly identical as possible, on every testing occasion. Standardizing a test is a very important process of administering the test to a representative sample of future test-takers in order to establish a basis for meaningful comparisons of scores. With that being said, reliability is the consistence or repeatability of a measure instrument. To establish reliability, researchers compare the consistency of test-takers’ scores on two halves of the test, alternate forms of the test, or retests on the same test. There are two types of reliability. Inter-Rater Reliability and Test-retest. Test-retest reliability is when the tester test the same people at different times but the participants should get the same results that he or she received on the previous test. The next reliability is Inter-rater and that is when multiple people are giving assessments of some kind or are the subjects of some test, then similar people should lead to the same resulting scores. It can be used to calibrate people, for example those being used as observers in an experiment. On the other hand, validity is the accuracy which a measuring instrument assesses the attribute that is designed to measure correlated with measures of school performance. In other words, validity refers to how well a test measures what it is purported to…
In addition, standardized tests help the students review what they know in one test because the standardized tests review all of the topics from before. Also the teachers are given time before and sometimes after the test to review things important from the year. Now some other people say that the test doesn’t cover but one big topic, but the topics are easily covered considering the amount of questions.…
- A norm referenced assessment makes judgments about people, on the basis of sources and distributions of scores. For instance, the top 10 percent of the class are awarded first class and the next 15 percent are awarded second class.…
Two examples of formal assessments are state standardized achievement tests and selected response evaluations given in the classroom. The state standardized achievement tests measure on a more global level than the selected response, but both are designed to evaluate a student's knowledge after the lesson has been given. A selected response evaluation can be essays, projects, fill-in the blank or multiple-choice types of tests. They succeed in measuring what the student can recall from the previous lesson or lessons. They also help measure what the majority of the class has learned or not learned and will help the teacher prepare for the next year's lesson planning. These test types can be used by teachers and principals to help design a school-wide…
A standardized test gives a lot of information not only to the kids, but also to the teachers. Standardized test is teaching the teachers at the same time because then they teacher has to learn the material that is on the test so that they can teach the students. The standardized test today has different subjects in each question. If a student is just reading a question on the test they might learn something from just reading the question.…
Schools across the United States are forced to give their students standardized tests. Standardized tests are multiple choice tests based on a list of state standards that a teacher is required to teach. The state makes schools give these tests to measure student achievement. In most schools, these tests go toward a big percentage of a student’s grade and in some cases determine whether the student will pass or fail a class. One can argue that standardized tests are useful; however, more people would argue that the tests are unfair and ineffective. Even though standardized tests are said to be useful in measuring student achievement, they should not be given because each student learns differently, they affect how much students will learn, they are harmful to student confidence, and some students are not good test takers.…
Standardized tests are often referred to as “assessments”. Assessments are often defined as the collection and analysis of information about one or more students. These so called standardized testing is a particular groups of students will take the same test that will be scored and analyzed the same way, then the students’ scores are compared to the rest of the group to see how well the students preformed. One of the federal law which is known as “No Child Left Behind” was created so that schools would be held accountable for what students learn through the school year. These standardized test are required to set goals and objectives for students starting in grade three and, at the end of the year, as whether students met the required goals…
Shelby Park Miss Sample and Mrs. Johnson Presentation Literacy 6 March, 2015 Standardized Tests: Impacting Students and Teachers Everywhere Standardized testing is a typical occurring activity across the United States. These tests are used to share the progress of students academically. Standardized tests vary from state to state since each state is allowed to design and create their own tests. However, there have been many arguments for and against standardized testing.…
