As the use of contracting for Information Technology (IT) services steadily increases, IT managers are challenged with reconciling the need for flexibility achieved through the use of contract workers, with the need to understand the factors that maximize the performance and behaviors of contract and permanent IT workers. While several research…

With the overarching goal of improving scientific literacy for all, the emphasis on science achievement had been expanding all over the world. In this study, I examined the total, direct and indirect effects of inquiry-based science instruction on U. S. 8th graders' science achievement through attitudes toward science. I also examined the…

The purpose of this paper was to test the relationship between principals' instructional leadership and teacher collaboration around instruction to determine whether these measures were statistically related and whether, together, they were associated with academic achievement in elementary schools. Data were obtained from 1605 teachers in 96…

Objective: The purpose of the current study was to demonstrate the replicable nature of statistical suppressor effects in coping research through 2 examples with African American adolescents from low-income communities. Method: Participants in the 1st example included 497 African American adolescents (mean age = 12.61 years, SD = 0.99; 57% female)…

Although studies investigating the validity of positive affectivity and negative affectivity in children have been supportive, investigations of changes in the structure of affect across childhood have demonstrated mixed results. The current study used confirmatory factor analytic techniques to test one-factor, two-factor correlated, and…

Past research has shown that valuing gender conformity is associated with both positive and negative consequences for self-esteem and positive affect. The current research (women, n= 226; men, n= 175) explored these conflicting findings by separating out investing in societal gender ideals from personally valuing one's gender identity ("private…

This study examines the association between adolescents' relational schemas and their subjective understanding of interactions in the context of male-female romantic relationships. We employed an innovative multimodal methodology: the video-recall system [Welsh, D. P., & Dickson, J. W. (2005). Video-recall procedures for examining subjective…

In this study, we compared the effects of two experimental multiple-strategy approaches (content-area comprehension and vocabulary) to typical fourth-grade social studies instructional practices. An 18-week, cluster-randomized study was conducted to estimate effects measured by normative-referenced reading comprehension and vocabulary measures and…

Although the role of school engagement in influencing children's academic competence has been recognized in past theory and research, how school engagement may mediate the relationships between ecological and personal resources and academic competence remains largely unknown. Using structural equation modeling procedures, the present study was…

This study examined pre-service teachers' self-reported behavioral intentions to use technology. Three hundred and fourteen participants completed a survey questionnaire measuring their responses to six constructs from a research model that extends the technology acceptance model (TAM) by including facilitating conditions and subjective norm.…

The aim of the current study was to examine the role of satisfaction-with-event as a mediator in the relations between flow and life satisfaction based on the bottom-up theory (Andrews and Withey in "Social indicators of well-being: Americans' perceptions of life quality." Plenum, New York, 1976; Lee et al. in "J…

Recently, the importance of ill-structured problem-solving in real-world contexts has become a focus of educational research. Particularly, the hypothesis-development process has been examined as one of the keys to developing a high-quality solution in a problem context. The authors of this study examined predictive relations between young…

The purpose of this paper was to investigate a model for describing the relationships between the extent to which learning environments are activating and students' interaction with teachers and peers, sense of belonging, and study success. It was tested whether this model holds true for both ethnic minority students and ethnic majority students.…
