The purpose of this study was to apply two types of Differential Item Functioning (DIF), net and global DIF, as well as the framework of Differential Step Functioning (DSF) to real testing data to investigate measurement invariance related to test language. Data from the Program for International Student Assessment (PISA)-2006 polytomously scored…

The OECD's Programme for International Student Assessment (PISA) enables participating countries to monitor 15-year old students' progress in reading, mathematics, and science literacy. The present study investigates persistent factors that contribute to science performance of Turkish students in PISA 2006 and PISA 2009. Additionally, the study…

A new vision of science learning described in the "Next Generation Science Standards"--particularly the science and engineering practices and their integration with content--pose significant challenges for large-scale assessment. This article explores what might be learned from advances in large-scale science assessment and…

From September 2015, schools in England will be teaching new A-level science specifications that have been developed by examination boards to encompass new higher levels of demand developed by the Department for Education. Integral to these new specifications is a radical change to the contribution of practical science to the A-level grade of the…

Laboratory courses serve as important gateways to science, technology, engineering, and mathematics education. One of the challenges in assessing laboratory learning is to conduct meaningful and standardized practical exams, especially for large multisection laboratory courses. Laboratory practical exams in life sciences courses are frequently…

This study investigated the application of multidimensional item response theory (IRT) models to validate test structure and dimensionality. Multiple content areas or domains within a single subject often exist in large-scale achievement tests. Such areas or domains may cause multidimensionality or local item dependence, which both violate the…

This article reports on the collaboration of six states to study how simulation-based science assessments can become transformative components of multi-level, balanced state science assessment systems. The project studied the psychometric quality, feasibility, and utility of simulation-based science assessments designed to serve formative purposes…

This paper considers uses of technology in educational assessment from the perspective of innovation and support for teaching and learning. It examines assessment cases drawn from contexts that include large-scale testing programs as well as classroom-based programs, and attempts that have been made to harness the power of technology to provide…

Standard setting is a method used to set cut scores on large-scale assessments. One of the most popular standard setting methods is the Bookmark method. In the Bookmark method, panelists are asked to envision a response probability (RP) criterion and move through a booklet of ordered items based on a RP criterion. This study investigates whether…

This article reports on reactions to the U.S. Department of Education's first time decision to sit out an international study designed to show how advanced high school students around the world measure up in math and science. Mark S. Schneider, the commissioner of the department's National Center for Education Statistics, which normally takes the…

Presents an evaluation of a 16+ Nuffield physics test. Lists topics covered on the test. Reviews student performance and indicates that the text discriminated at both ends of the ability range. (SK)

The history of the Oxford Local Examinations is discussed beginning with the first examination in 1856 and including the advent of the General Certificate of Education examination in the late 1940s. (SA)

Describes the impact of North Carolina's testing program in chemistry on curriculum and instruction from teachers' perspectives. A random sample of 100 teachers received a questionnaire yielding a usable sample of 48, of which 8 were interviewed. Results suggest testing is making the chemistry curriculum more uniform across the state. It is not…

Examines trends in science testing and discusses its impact on science instruction. Presents data on each state's assessment program in science for grades K-8. Identifies the type of test, grade tested, the scope and frequency, and the contact person for each of the 50 states. (ML)

Provides information on the American Chemical Society's (ACS) 1986 testing program, listing currently available tests (includes five new tests). Also provides condensed norms for ACS examinations, including high school chemistry forms 1985 and 1985-S, general-organic-biological chemistry form 1985, general chemistry (brief version) form 1985-B,…
