This study provides the results of a latent class analysis (LCA) using data from the Trends in International Mathematics and Science Study -- 2011 (TIMSS-2011) with a focus on the 8th grade mathematics section. The study presents the analysis of item data with Mplus 7.31 to determine if results obtained yielded distinct latent subgroups. The data…

The author of this paper describes the responsibilities of the National Assessment Governing Board, of which she served as a member from November 1997 to September 2004. The Board is unlike any other board of which she has been a member. At the quarterly meetings, the Board not only discusses and makes major policy decisions but determines the…

This study was an expanded replication of an earlier endeavor (Shermis, Burstein, & Bliss, 2004) to document the writing outcomes associated with automated essay scoring. The focus of the current study was on determining whether exposure to multiple writing prompts facilitated writing production variables (Essay Score, Essay Length, and Number…

The paper deals with the facts obtained from TIMSS 2003 (Trends in International Mathematics and Science Study). This international comparative study, which includes 47 participant countries worldwide, explores dependence between eighth grade students' achievement in the areas of mathematics, physics, chemistry, biology and geography, and basic…

This study used data from the Third International Mathematics and Science Study (TIMSS) to determine trends in calculator use among Population 2 (13-year-olds) students in Japan, the United States, and Portugal. While relatively high levels of calculator use were observed for the U.S. and Portugal, virtually no calculator use was found in the…

Rather than describe mean gender differences in mathematics across different cultures, this study instead focused on an in-depth item analysis across two countries, the United States and Spain. The purpose of this study was to investigate gender differences on multiple-choice mathematics items across two countries by using the data gathered in the…

The Third International Mathematics and Science Study (TIMSS) is the largest, most comprehensive, and most rigorous international comparison of education ever undertaken. TIMSS findings show similarities and differences in the processes and outcomes of schooling between the United States and East Asian countries, particularly Japan. This report…

This study examined the generalizability of the internal/external (I/E) frame of reference model of academic self-concept development. The "external" component of the model refers to comparing one's achievement with one's peers; in LISREL causal modeling, this external comparison is presented as positive paths. The "internal"…

This investigation examined students attending U.S. and Canadian visual and performing arts secondary schools for distinguishing personality characteristics, locus of control, acceptance of talents, labeling, family dynamics, anxiety levels, perceived personal and school problems, and views of peers, artists/teachers, and counselors. One hundred…

Item response theoretic methods are applied to the measurement of achievement of students from various instructional backgrounds. This extended item response theory (IRT) approach serves as a tool for studying instructional bias, or instructional sensitivity. The model maintains the form of an IRT model, but has parameters that quantify the extent…
