This study investigated their views concerning evidence and expert opinion of 10th-grade students, accessed by an open-ended questionnaire in the context of a socio-scientific issue: the cause of flood disasters, and personal epistemology identified by the "Learning Environment Preference Questionnaire" (LEP). Students' responses to the open-ended…

This report presents information on similarities and differences between U.S. high school sophomores as studied at three points in time over the past 22 years, with a focus on cohort demographics, academic programs and performance, extracurricular activities, life values, and educational/occupational aspirations. It provides an update to the…

In this article, a heterogeneous latent growth curve model for modeling heterogeneity of growth rates is proposed. The suggested model is an extension of a conventional growth curve model and a complementary tool to mixed growth modeling. It allows the modeling of heterogeneity of growth rates as a continuous function of latent initial status and…

This is one of a series of reports on the National Longitudinal Study of Mathematical Abilities (NLSMA). Further, it is of the subseries that analyzed data for the purpose of identifying differential patterns of mathematical achievement which are correlated with different textbook series. This particular report considers comparisons made for the…

Draws on data from 1988 National Education Longitudinal Study to estimate the impact of block-scheduled mathematics course on 10th-grade student achievement and teachers' use of class time. Findings suggest that while block scheduling is positively associated with teachers' use of multiple instructional methods and more individualized instruction,…

The belief that schools can play a powerful role in preventing tobacco use among adolescents has led to the implementation of various tobacco-related polices and practices. This study examines the association between school policies regarding monitoring student behavior, severity of action taken for infraction of policies, and tobacco use by…

In this investigation I focused on a process of activities of a particular group of teachers and learners. Basic skills in mastering mathematical concepts were addressed. The focus was on concept formation in the geometry classroom. The methodology involved an educational case study as a form of inquiry to investigate spatial sense. Evidence was…

The data for this report describe the tested achievement and educational status of a cohort based on a nationally representative probability sample of 15,362 10th-graders in 752 public, Catholic, and other private schools, who were studied in the spring term of the 2001-02 school year. The base-year data collection for the Education Longitudinal…

The standards-based reform movement in education that began in the 1980s has evolved. In the 1990s, the focus was on producing subject-area content standards and modifying instruction. Today, the focus has shifted to assessment, and for technology education, demonstrating the impact on children and the efficacy of the discipline within general…

The "recurring author" is one whose works appear many times at different levels in instructional units found in literature textbook series. A descriptive case study discussed the treatment of a recurring author, William Shakespeare, using units in a sample of six literature textbook series. Developed to describe, to code, and to analyze…

The previous theoretical development of the Poisson process as a strong model for the true-score theory of mental tests is discussed, and additional theoretical properties of the model from the standpoint of individual examinees are developed. The paper introduces the Erlang process as a family of test theory models and shows in the context of…

The specific research objective of this paper was to make racial comparisons on the consistency dimension of the projected frames of reference of adolescent males from the rural South. Data were obtained from a population of high school sophomores in 3 Texas and 2 Georgia counties. Complete data were available for 223 white and 192 Negro males.…

The study compares overexcitability scores of Turkish 10th graders who are grouped in terms of their intellectual abilities, motivation, creativity and leadership as well as gender. 711 students who were administered Raven Advanced Progressive Matrices Test (APM) were divided into three intellectual ability categories. From this pool, 105 subjects…

The purpose of this study was to identify misconceptions concerning chemical equilibrium concepts and to investigate the effectiveness of instruction based on the constructivist approach over traditional instruction on 10th grade students' understanding of chemical equilibrium concepts. The subjects of this study consisted of 71 10th grade…
