The present study investigated children's conceptions of and relations to nature. Understanding the factors that influence them was the goal. The study used the Contextual Model of Learning as the theoretical framework to structure the research questions and data analysis to understand children's nature learning in the personal, sociocultural, and…

Ever since achieving a high school credential by passing the GED[R] test became widely institutionalized through adult education programs in the United States, outcomes for GED test credential recipients have continued to be of great interest to the adult education community and the general public.

Quality measurement serves as a foundation for child care Quality Rating and Improvement Systems (QRIS). Understanding the variation that exists in quality measurement, the different contexts in which states make decisions, and the factors that play into their decisions can help administrators identify where their state may fall along the spectrum…

This article describes implementation experiences "scaling up" the Cognitive Behavioral Intervention for Trauma in Schools (CBITS)--an intervention developed using a community partnered research framework. Case studies from two sites that have successfully implemented CBITS are used to examine macro- and school-level implementation…

Most measurement techniques have some limitations imposed by a sensor's signal-to-noise ratio (SNR). Thus, in analytical chemistry, methods for enhancing the SNR are of crucial importance and can be ensured experimentally or established via pre-treatment of digitized data. In many analytical curricula, instrumental techniques are given preference…

This article describes the development of a ten-item scale to assess biology majors' self-efficacy towards the critical thinking and data analysis skills taught in an upper-division cell biology course. The original seven-item scale was expanded to include three additional items based on the results of item analysis. Evidence of reliability and…

Processes of psychological empowerment for members of community-based organizations may be strongly influenced by organizational factors. Using survey data from a random sample of urban residents (n = 974), the present study examines how individual perceptions of empowering features of organizations (group-based belief system, role opportunity,…

The purpose of this study was to analyze how school psychologists engaged in problem analysis during problem-solving consultation. Five aspects of the problem analysis process were examined: 1) the types of questions participants asked during problem identification, 2) the types of data participants requested, 3) the frequency of requests for each…

In this article a continuous-time stochastic model (the Ornstein-Uhlenbeck process) is presented to model the perpetually altering states of the core affect, which is a 2-dimensional concept underlying all our affective experiences. The process model that we propose can account for the temporal changes in core affect on the latent level. The key…

The science education literature clearly shows that knowledge of the nature of technology is an educational goal; however there is a lack of research on student conceptions about the nature of technology. To address this gap in the literature, this research began with a thorough review of the literature on scientific and technological literacy,…

The purpose of this study was to examine the extent to which three teachers' professional experience and existing orientations toward teaching and learning mathematics and science influenced their implementation of a project-based curriculum (i.e. project-based learning (PBL)). Data sources included interviews, videotapes of classroom activity,…

The word "data" connotes math, science, and technology: digits and quantifiable units. Data imply objectification--reducing ideas, and perhaps even students and teachers, to products that can be measured and compared. Ironically, however, this conception of data is itself reductive, and it minimizes the richness and potential of data.…

Using data from the Fragile Families and Child Wellbeing Study, we examined whether mothers' (N = 4,127) and fathers' (N = 3,405) relationship status influenced their activation of financial support from relatives over time. We found that relationship status influenced the activation of financial support from relatives but that the effects…

This study considers the relationship between federal academic earmarks and state appropriations for higher education. Often referred to as "pork," federal academic earmarks are both controversial and understudied. Using a unique panel dataset which spans 1990-2006, this study conducts a panel analysis with two-way state and year-fixed effects. It…
