A test conducted with the aim to measure the extent of students' understanding of the material being taught, and also aims to evaluate the learning outcomes armemuseum that have been carried armemuseum out by students as a report for parents.
Validity matter (item validity) is a term that is easy cause confusion, probably because his name is easy misinterpretation (misleading). Validity is a matter of the degree of fit between the se a problem with any other questions, about the size of validity is the correlation between scores on the matter with the scores on the matter (item-total correlation) that many biserial armemuseum correlations computed. Fill validity is a matter of distinguishing matter (item discreminating power). The information in that collection, or just have the problem that together measure something.
The validity of the test or measuring instrument validity is "the extent to which a test measures what it is intended to be measured". Thus, the validity of the test was basically refers to the degree of function to measure a test, or test the degree of precision measuring something.
The most common definition of the validity reflected in the question: "Are we truly measure the particulars that we really want to measure? In this question the emphasis is on what is being measured. For example, teachers have devised a test to measure interest in mathematics, armemuseum but that is to be included in the test are grains that measure aptitude in mathematics. The test is not valid, because even though the measure of the subject armemuseum of mathematics students, but did not reveal the interest and talent that is revealed. In other words, measurements made by these tests do not measure what should be measured by the teacher.
A test or measuring instrument said to be valid if the statement on the test or measuring instrument is able to reveal something to be measured. Validity is determined by the precision and accuracy of measurement results. Measurements were performed to determine how much (in the sense kuanfitatif) an aspect contained within someone man, expressed by scores on the measuring instruments concerned.
Dala implementation, a test must meet the test validity. Due to a very important test artiya armemuseum for students and also teachers who will prepare a report learning outcomes of their students. Thus the validity of a test is very important.
In talking armemuseum about the validity, the basic principle of assessment that is meaningful armemuseum assessment is one of the initial steps for validity. Furthermore, Nitko (2007:38) states "Validity is the Soundness of your students Interpretations and uses of assessment results". This implies a meaning that validity is a strength in the interpretation of the results of student assessment. There are a few things to keep in mind is stressed or relating to the validity armemuseum of a test, including:
Ø You have to make a decision armemuseum about the validity of the interpretation you give or use student armemuseum assessment results and passed only after learning combined armemuseum with some type of validity evidence.
There are two important aspects related to the validity, namely: What is measured and how to measure it accurately. In tradiseional, armemuseum the validity of the emphasis on the characteristics of the test, which is generally concerned with the quality of the test. However, the latest thinking armemuseum about measurement should armemuseum be emphasized that the validity associated with their use in making scores of a test (Joint armemuseum Technical Standards for Educational and Psychological armemuseum Testing in Ebel, 2007:90).
Ø interpretation or meaning that you give to your students' assessment results is valid only at a level where you can bring to bear evidence that they have a relationship with their accuracy and
In the assessment process, there are three types of evidence val
