The purpose of this study was to investigate the 'locality' of the relationship between attitudes towards science, self-beliefs and science achievement for senior high school students in Australia, Cyprus and the USA. These relationships were examined with the use of the structural equation modeling software, AMOS. The data for this study were…

Structural equation models of the same construct collected on different occasions are evaluated in 2 studies involving the evaluation of 157 college instructors over 8 years and data for over 2,200 high school students over 4 years for the Youth in Transition Study. Results challenge overreliance on simplex models. (SLD)

Students today are different from their counterparts of three and four decades ago. Women have outnumbered men for more than 15 years, and the participation rates for members of historically underrepresented groups have made impressive gains. Many of these "new" students are the first in their families to attend college. It is important that these…

This study investigated students' conceptions of constructivist learning activities in a problem-based learning (PBL) and a traditional curriculum. We examined whether students who have chosen for a problem-based curriculum have different conceptions of constructivist assumptions compared to students who have chosen to be enrolled in a…

Poor social skills and behavioral problems are a major component of ADHD. The different explanations offered so far, such as cognitive deficits and deficient self regulation, have not been able fully to account for the various aspects of the social dysfunction, suggesting that other mechanisms might underlay this impairment. Our study sought to…

Uses structural equation modeling to combine traditional ideas from repeated-measures ANOVA with some traditional ideas from longitudinal factor analysis. The model describes a latent growth curve model that permits the estimation of parameters representing individual and group dynamics. (Author/RH)

Examined connections between parents' work pressure and adolescent adjustment in 190 dual-earner families. Found that effects of work pressure on adolescent well-being were mediated by parental role overload and parent-adolescent conflict. Fathers' work pressure predicted both parents' feelings of role overload. Mothers' work pressure predicted…

Several goodness of fit (GOF) criteria have been developed to assist the researcher in interpreting structural equation models. However, the determination of GOF for structural equation models is not as straightforward as that for other statistical approaches in multivariate procedures. The four GOF criteria used across the commonly used…

Measuring and linking competencies require special instruments, special data collection designs, and special statistical models. The measurement instruments are tests or tests forms, which can be used in the following situations: The same test can be given repeatedly; two or more parallel tests forms (i.e., forms intended to be similar in…

Three models of achievement motivation in the classroom are contrasted. Results with 155 high school students suggest that the model of C. S. Dweck and E. S. Elliott offers a better explanation of the relationships among achievement motivation, attributions, emotional reactions, expectancies, and performance than do the other models. (SLD)

An empirical research study based upon the expectancy-value model of Eccles and colleagues (1983) investigated the effect of gender-role orientations on psychological dimensions of female athletes' sport participation and the likelihood of their continued participation in a stereotypical masculine activity. The model (Eccles et al., 1983) posits…

Empirical evidence of no age-related decline in life satisfaction (LS) in old age contrasts with frequently observed declines in the objective quality of elder people's lives and has therefore been labelled a "paradox" and interpreted in terms of stability of LS in the respective gerontological discussion. However, as this evidence was…

Used short-term longitudinal design to examine peer relations processes that may mediate relation between peer rejection and kindergartners' emotional and academic adjustment. Structural equation modeling results supported hypothesis that negative peer treatment and classroom participation partially mediated the relationship between rejection and…

The study compares two groups of students who graduated from high school in the Milwaukee Public Schools (MPS) during 1997-2001. Students who had participated in MPS Montessori programs from preschool through 5th grade were matched to a comparison group on the basis of gender, SES, race/ethnicity, and high school attended. Data from the ACT and…

The widespread use of student evaluations to rate faculty has raised the question of whether high student evaluations can be gained simply through the process of faculty giving higher grades to students, or whether learning of students is a critical factor in such evaluations. Four different models were tested which represented different…
