Predicative Validity
Jong, John. Predicative validity
The predicative validity is how a test is able to predict the behavior of a candidate after taking a test. Professor John de Jong used as an example of students taking a test to be enrolled into a university. There are three things that could be useful for student achievement when using predicative validity. Students who take the state standardized test such as the EOG are placed in student in specific classrooms based on their ability levels. Students who take the state standardized test are compared to other students according to the standard course of study across state. Students who take the state standardized test/ or classroom-based test that will allow teachers to determine whether or not they have mastered the material. There are also three things that could be useful for teachers and administrators. The teacher can determine a focus by which to re-teach material if students did not meet the expectation. Administrators can examine programs to help students obtain skills that are lacking. Administrators can offer staff development for teachers in order to help students meet expectations. In my research, using the assessment tools in the Corrective Reading is a predictive assessment which determines the placement in which to begin the intervention for reading fluency and comprehension.
Standard Error of Measurement
There are two key ideas that Dr. LeBlanc emphasizes in this you tube: validity and reliability. Validity is when the test measures what it is suppose measure. Reliability is how consistent the assessment to be measured is it is. Standard error of measurement is the mathematical way to estimate the amount of error in any given measurement of variability. It is usually +3 or -3 pts from standard error of measurement. It is the relationship between the Standard Error of Measurement and reliability. If the reliability is high then the standard error of measurement will be smaller and vice versa. When looking at the states for reliability there are factors that make an assessment more reliability. Dr. LeBlanc talks about the subjects by which taking the test should be at a minimum of 30. The items on the test should also be at least 30 for good reliability. There are three things that could be useful for student achievement. When noting the reliability of the test makes sure that your sample of test is accurate in measurement of the table of specification. There are three things that could be useful for student achievement. For students, one of the ways to examine the reliability of the test is to determine whether or not the test is valid. Teachers can determine by classroom-based assessments if the student has grasped the information by re-taking the test and providing an average. When making a test, students achievement may be examined by making sure that the questions on follow the guidelines of table specification (Bloom’s Taxonomy). When viewing the student assessments in is a useful to determine what items are adequate. Students may need further remedial from the teacher. There are three things that could be useful for teachers/administrators. Often when psychologist and teachers are determining the eligibility of students we look at test such as the Woodcock Johnson and the WISC to predict how they relate to other students their age academically and cognitively. When determining the reliability, teachers could check there test with other teachers (collaboration) in our school we are using common assessments to identify what should be taught in the classroom. In the planning of instruction teachers can examine the standards by which to concentrate and then devise a plan for students to reach the desired outcome.

Validity
When looking at the validity of the assessment one may examine the most important items and how the assessment is designed to measure. For example a standardized test and a teacher made test. When looking at the content of the assessment the standards are what are taught. When looking at construct, the quality of the test is viewed. There are three things that could be useful for student achievement. When focusing on the content be aware that the test focuses on the standards and objectives for what is taught. Student can identify the objective and can do a self-assessment to determine what they have learned. For teachers administrators may have test be examined by panel of experts other teacher, making suggestions to improve test as well in common planning. The use of the matrices such as the table of specification can help teachers in common planning to identify the levels of thinking and assessed the levels. The construct validity assessments are commonly used for knowledge skills, aptitude, and efficacy and empathy test. These tests are usually examined by a panel in order to focus on the standard error of measurement.
“Anything not understood in more than one way is not understood at all”. Measurement, assessment and evaluation mean very different things. Measurement is the process of the attributes or dimensions of some physical object are determined. Collection of data relative to some established rule or standard. Assessment is information obtained to some known objective or goal. Evaluation it is the process that is engaged to provide information to make judgment about a situation. The information from this article was very useful in distinguishing the differences between measure, assessment and evaluation. Student achievement is assessed through facets of classroom based test. Teachers are then evaluated from the assessment the academic needs of the student and determining the goals and objectives to teach. When looking at my research project there are components within the project in which the student’s can be measured by their successes and the assessments are taking by the objectives that they reach for the lesson. Before, during and after the teacher and the student may have opportunities to evaluate the process of the intervention or determine their needs. As a teacher and administrator, deciphering the difference between measurement, assessment and evaluation is significant because it allows for more in depth study of useful programs that you may want to include in your school.

In viewing the purposes of assessments, I found it very useful to students teachers and administrators that when you are finding an assessment make sure that you follow the following guidelines : 1)Assessment is inherently a process of professional judgement. 2)Assessment is based on separate but related principles of measurement evidence and evaluation. 3) Assessment decision-making is influenced by a series of tensions=motivate and engage students in ways that are consistent with their philoso[phies of teaching and learning. Different factors influence the nature of the assessment. 4)Asssessment influences student motivation and learning- how do students study or motivated to study when it is multiple choice items. 5)Assessment contains error- teachers and administrators need to not only know that there is error in all classroom and standardized assessments. 6)Good assessment enhances instruction – the use of diagnostic assessments can be a driving tool for instruction. 7)Good assessment is valid. 8)Good assessment is fair and ethical. 9) Good assessment is efficient and feasible. 10) Good assessment appropriately incorporates technology.
