Children and adolescents are exposed to multiple contextual influences along their development towards adulthood. Before they transition to adulthood, adolescents acquire skills and knowledge usually in schools, which are one of the most influential contexts during adolescence. During school years performing well academically can generate better…

Nonlinear multilevel latent variable modeling has been suggested as an alternative to traditional hierarchical linear modeling to more properly handle measurement error and sampling error issues in contextual effects modeling. However, a nonlinear multilevel latent variable model requires significant computational effort because the estimation…

The purpose of the study is to further investigate the validity of instruments used for collecting preservice teachers' perceptions of self-efficacy adapting the three-level IRT model described in Cheong's study (2006). The focus of the present study is to investigate whether the polytomously-scored items on the preservice teachers' self-efficacy…

This exploratory study examined the associations between teacher-student relationship ratings and characteristics of students and teachers. A sample of fifth grade teachers (N = 115) and their students (N = 2070) were studied. Hierarchical linear modeling was employed to explore the associations between variables while taking both individual…

Interest in whether real-world problems or a service learning context increases students' academic performance and intent to find careers in engineering is gaining momentum. The belief that diverse student populations resonate with the idea that "engineers can contribute to improving society" is found throughout the literature,…
