Attali (2005) recently demonstrated that Cronbach's coefficient [alpha] estimate of reliability for number-right multiple-choice tests will tend to be deflated by speededness, rather than inflated as is commonly believed and taught. Although the methods, findings, and conclusions of Attali (2005) are correct, his article may inadvertently invite a…

If a person were to ask an educator to identify the two most important attributes of an education test, the response most certainly would be "validity and reliability." These two tightly wedded concepts have become icons in the field of education assessment. As far as validity is concerned, the term doesn't refer to the accuracy of a test. Rather,…

Understanding students' prior beliefs in nuclear physics is a first step towards improving nuclear physics instruction. This paper describes the development of a diagnostic survey in nuclear physics covering the areas of radioactive decay, binding energy, properties of the nuclear force and nuclear reactions, that was administered to students at…

This technical report provides detailed information regarding the technical, statistical, and measurement attributes of the New York State Testing Program (NYSTP) for the Grades 3-8 Common Core English Language Arts (ELA) and Mathematics 2014 Operational Tests. This report includes information about test content and test development, item (i.e.,…

This paper developed a Democratic Classroom Survey to measure students' perceived democratic environment of the classroom. Perceived democratic environment is one of the most important variables for understanding classroom activity and indeed any type of group activity, but actually measuring perceptions in an objective manner has been…

States and school districts are exploring alternatives to state tests for measuring teachers' contributions to student learning. One approach applies statistical value-added methods to alternative student assessments such as commercially available tests and end-of course tests. The evidence suggests that these methods can reliably distinguish…

Alternative approaches are discussed for use of e-rater[R] to score the TOEFL iBT[R] Writing test. These approaches involve alternate criteria. In the 1st approach, the predicted variable is the expected rater score of the examinee's 2 essays. In the 2nd approach, the predicted variable is the expected rater score of 2 essay responses by the…

In the arena of educational testing, accessibility refers to the degree to which students are given the opportunity to participate in and engage a test. Accessibility theory is a model for examining the interactions between the test-taker and the test itself and defining how they may decrease some students' access to the test event, ultimately…

Learning environment studies acknowledge that learning takes place within the social realm and that social conditions contribute to the quality of both learning and experience. This can be said to be especially true for environmental learning programs. To access information about students' perceptions of their learning environment, a robust…

At the heart of most assessments lies a set of questions, and those who write them must achieve "two" things. Not only must they ensure that each question elicits the kind of performance that shows how "good" pupils are at the subject, but they must also ensure that each mark scheme gives more marks to those who are…

The Chinese have been using standardized testing for centuries. Ancient Greeks have tried it for centuries since 5th and 4th BC. There is no evidence that they have become successful in educating their children through an imperial or elitist system. The impact of standardizing the education on a nation is significant. This is not only true for not…

The measurement of dental fear is important due to its high prevalence and appreciable individual, clinical, and public health consequences. However, existing measures of dental anxiety and fear (DAF) have theoretical or practical limitations. This study describes the development and subsequent assessment of the reliability and validity of test…

Data driven decision making emphasizes the importance of the teacher using objective sources of information in developing the social studies curriculum. Too frequently, decisions of teachers have been made based on routine and outdated methods of teaching. Valid and reliable tests used to secure results from pupil learning make for better…

State test scores administered for accountability purposes are regularly used to adjust instruction in nuanced ways. This is no accident--No Child Left Behind demanded that students' scores be returned quickly to teachers in order that this might be the case, and the idea of data-driven decision making continues as one way the promise of education…

No one has a bigger stake in teaching effectiveness than students. Nor are there any better experts on how teaching is experienced by its intended beneficiaries. Only recently have many policymakers and practitioners come to recognize that--when asked the right questions, in the right ways--students can be an important source of information on the…
