Informal Reading Inventories (IRI) are often recommended as instructionally relevant measures of reading. However, they have also been criticized for inattention to technical quality. Examination of reliability evidence in nine recently revised IRIs revealed that fewer than half report reliability. Several appear to have sufficient reliability for…

Little is known about environmental concerns and attitudes among people in former Soviet bloc countries in Eastern Europe despite widespread perceptions of severe environmental problems. The authors addressed this gap by examining Bulgarians' environmental concerns with a focus on whether the new environmental paradigm (NEP) scale can reliably…

The development of the DETECT procedure marked an important advancement in nonparametric dimensionality analysis. DETECT is the first nonparametric technique to estimate the number of dimensions in a data set, estimate an effect size for multidimensionality, and identify which dimension is predominantly measured by each item. The efficacy of…

Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) have contributed to test development and validation in counseling psychology, but additional applications have not been fully realized. The author presents an overview of the goals, terminology, and procedures of factor analysis; reviews best practices for extracting,…

Researchers sometimes need a statistical test of the hypothesis that two values of Cronbach's alpha reliability coefficient are equal. The situation may involve scores from two different measures administered to independent random samples or from the same measure administered to random samples from two different populations. Feldt derived a test…

Cudeck and Browne (1983) proposed using cross-validation as a model selection technique in structural equation modeling. The purpose of this study is to examine the performance of eight cross-validation indices under conditions not yet examined in the relevant literature, such as nonnormality and cross-validation design. The performance of each…

The study of the structure of research articles has developed into a significant field of research. The original research focus on texts produced by English academics has been expanded over the years to allow for the investigation of the structure of texts written by academics publishing in various other languages. The ongoing discussion between…

In low-stakes testing, the motivation levels of examinees are often a matter of concern to test givers because a lack of examinee effort represents a direct threat to the validity of the test data. This study investigated the use of response time to assess the amount of examinee effort received by individual test items. In 2 studies, it was found…

The purpose of this investigation was to apply a validated curriculum evaluation instrument, the "Science Curriculum Implementation Questionnaire" (SCIQ), in an educational context in which a science curriculum review had recently been completed and, by so doing, ascertain the accuracy and potential value of the instrument as a…

School vouchers, particularly since the landmark U.S. Supreme Court ruling on the Cleveland program, are one of the most contentious issues in American education. Seemingly contradictory results across available studies have caused confusion among diverse audiences. The authors suggest that these divergent findings are, in part, due to three…

Research on student assessment in online environments has not been extensive, although manuals for instructors provide broad guidelines and specific procedures. In this article we review the most frequently reported approaches to online assessment in postsecondary settings, giving particular attention to systems for assessing the quality of…

Adult and continuing education practitioners must engage in continuing professional education as a means of developing and maintaining their professional competence. This paper reviews the literature on competencies for continuing educators and examines the strengths of existing instruments for continuing educators to self-assess their…

School principals have difficulty embracing the competing demands of school restructuring. These demands include being accountable for the outcomes of other decision-making groups within, or external to, the school community; having strong views while making decisions collaboratively; and using group processes without wasting the time, commitment,…

The science epistemological beliefs of students have been found to play an important role in determining their learning orientations towards science. Conley, Pintrich, Vekiri, & Harrison (2004) developed a measure to examine the epistemology beliefs of students about science. The measure encompasses four dimensions about scientific knowledge:…

An introductory CS1 course presents problems for educators and students due to students' diverse background in programming knowledge and exposure. Students who enroll in CS1 also have different expectations and motivations. Prompted by the curricular guidelines for undergraduate programmes in computer science released in 2001 by the ACM/IEEE, and…
