Background/Context: Mixed methods research conveys multiple advantages to the study of complex phenomena and large organizations or systems. The benefits are derived from drawing on the strengths of qualitative methods to answer questions about how and why a phenomenon occurs and those of quantitative methods to examine how often a phenomenon…

The study explored facets of identity formation considered to be of significance by Zimbabwean female adolescent students in physics. Four high schools that were offering physics at A' level in the Midlands Province, in Zimbabwe were targeted. Nine female adolescents doing mathematics and physics and only mathematics were chosen. Data generation…

Drawing on a larger study on "Gender practices and violence between peers: the stakes of mixed-sex education", this paper examines the methodological challenges specific to carrying out ethnography in an elite high school. The researcher's subjective experience in the field reveals the power dynamics at play in the elite setting. We also…

Plasticizers are chemical additives that enhance plastic flexibility. They are ubiquitous environmental contaminants and are commonly found in river and lake waters (Fromme et al 2002). The present study aimed to investigate the effects of a water-soluble plasticizer, dibutyl phthalate (DBP) on developing Medaka ("Oryzias latipes") embryos. Three…

Recently, teacher training courses have attracted the researchers' special attention, while teacher education programs have not received as much attention. The present study investigated the attitudes key stakeholders in a teacher education program (i.e., student teachers, in-service teachers, and teacher educators) hold toward the appropriateness…

The concept of "implementation fidelity" is broadly used to capture the extent to which an intervention is executed as intended by the designers of the intervention (Century, Rudnick, & Freeman, 2010; Huntley, 2005, McNaught, Tarr, & Sears, 2010, Munter, 2010). Though implementation fidelity instruments are often used to assess…

To support the implementation of the Common Core State Standards (CCSS), the Bill and Melinda Gates Foundation invested in the development and dissemination of two tools aimed at operationalizing classroom instruction based on the standards: (1) the Literacy Design Collaborative (LDC)'s Framework; and (2) the Math Design Collaborative (MDC)'s…

Conducting observational investigations of behaviors and processes is an important method for generating scientific knowledge. This article describes a methodology for assisting students in the processes of observational inquiry and theory articulation and its instantiation in a set of digital video tools. We describe a high school biology…

Background/Context: Technological and economic changes have put a high premium on developing students' information literacy and research skills. Previous attempts to deploy educational technology toward these ends have proved disappointing because K-12 teachers have difficulty integrating shared computers into instruction. In response, numerous…

Research indicates that peer interaction can have a substantial impact on the lives of adolescents with disabilities. However, social interaction among adolescents with intellectual disabilities and their general education peers typically occurs infrequently in secondary schools. This paper provides a critical analysis of twenty-six empirical…
