Recently, many organizations involved in environmental education have initiated programs that aim to educate visitors or other publics who interact with nature-based resources about the impacts and landscape transformations occurring because of climatic changes. However, many psychological, human-evolutionary, and social–ecological processes that impede individuals’ ability to notice or respond to (e.g. adaptation and mitigation behaviors) climate impacts in nature-based areas, or in their urban-based home communities, may influence the educational process. By reviewing and examining these foundational processes and their potential influence on an audience’s attitudes and beliefs towards climate change, we outline and explain their importance for research. Based on these important psychological, human-evolutionary, and social–ecological processes, the authors conclude by identifying how researchers can investigate the influence of these processes and their potential impacts on environmental education outcomes.  相似文献

This paper evaluates the impact of varying implementation of electronic lab order entry management (eLAB) system strategies on hospitals’ productivity in the short run. Using the American Hospital Association's Annual Surveys for 2005–2008, we developed hospital productivity measures to assess facilities’ relative performances upon implementing eLAB systems. The results indicate that different eLAB system implementation strategies were systematically related to changes in hospitals’ relative productivity levels over the years studied. Hospitals that partially implemented an eLAB system without completing the roll-out experienced negative impacts on productivity. The greatest loss in short-term productivity was experienced by facilities that moved from having no eLAB system to a complete implantation in one year—a strategy called the “Big Bang”. The hybrid approach of a limited introduction in one period followed by complete roll-out in the next year was the only eLAB system implementation strategy associated with significant productivity gains. Our findings support a very specific strategy for eLAB system implementation where facilities began with a one-year pilot program immediately followed by an organization-wide implementation effort in the next period.  相似文献

Why are some teachers more effective than others? The importance of understanding the interplay between teacher preparation, pedagogy and student achievement has motivated a new line of research focusing on teacher knowledge. This study analyses the effects of teacher mathematics knowledge on student achievement using longitudinal data from rural Guatemalan primary schools. After presenting a conceptual framework for linking the work of the teacher with student learning in mathematics together with an overview of the different forms of teacher knowledge, the paper introduces the Guatemalan context and the analytical framework including the sample, data and methods. Overall, the results provide some empirical support for a widely held, if infrequently tested, belief in mathematics education: effective teachers have different kinds of mathematical knowledge. The results also suggest specific mechanisms by which effective teachers can make substantial impacts on student learning, even in extremely poor contexts.  相似文献

The role of generational status (first-generation vs. continuing-generation college students) as a moderator of the relationship between psychological factors and college outcomes was tested to determine whether generational status acts as a risk factor or as a sensitizing factor. The sample consisted of 322 undergraduate students who completed online measures of self-esteem, locus of control, and academic adjustment and provided self-reports of GPA. Generational status significantly moderated the relationship between psychological factors and academic outcomes. Generally, it was found that the relationship between psychological factors and academic outcomes were strongest among first-generation students. Further, it was found that for the majority of the interactions with locus of control, first-generation status acted as a sensitizing factor that amplified both the positive and negative effects of locus of control. In contrast, for self-esteem, first generation status acted as a risk factor that only exacerbated the negative effects of low self-esteem. These results are interpreted as reflecting motivational differences between first- and continuing-generation students and are discussed with respect to the social/cultural capital hypothesis that is most frequently presented in the existing literature.  相似文献

ABSTRACT

Medical student use of lecture video (live-streaming and/or recorded) at a regional medical school campus that utilized distance educational technology to deliver first-year pre-clinical lecture content, was examined. Additionally, medical student video lecture use was compared to student performance on summative exams and final course grades. All learners achieved desired scientific competencies across all courses irrespective of their use of live-streamed or recorded video formats. Throughout the course of the year, medical student video use partitioned into one of two groups: students that only watched lecture in live-streaming format, and those that watched lecture only in recorded format. Interestingly, those medical students that predominantly preferred view lectures using the live-streaming format tended to achieve better summative test scores and final course grades compared to their peers that primarily utilized recorded video to obtain lecture content. Retrospectively, dimensions of personality scores were compared between the two groups (live-streaming viewers versus recorded viewers), and, of the five dimensions of personality, only the domain of conscientiousness differed between the two groups. This study suggests that, while medical students reached academic milestones utilizing either recorded or live-streamed video for obtaining lecture content during their first-year pre-clinical courses, there may be factors of learner personality influencing video use preference which in turn enhances student performance on summative exams and final course grades. These findings may have implications in curriculum design for other distance educational formats emphasizing classical scientific competencies in post-undergraduate study that rely on video delivery of lecture content.  相似文献

We present the development and validation of a science notebook rubric intended to measure the academic language and conceptual understanding of non-mainstream students, specifically fifth-grade male and female economically disadvantaged Hispanic English language learner (ELL) and African-American or Hispanic native English-speaking students. The science notebook rubric is based on two main constructs: academic language and conceptual understanding. The constructs are grounded in second-language acquisition theory and theories of writing and conceptual understanding. We established content validity and calculated reliability measures using G theory and percent agreement (for comparison) with a sample of approximately 144 unique science notebook entries and 432 data points. Results reveal sufficient reliability estimates, indicating that the instrument is promising for use in future research studies including science notebooks in classrooms with populations of economically disadvantaged Hispanic ELL and African-American or Hispanic native English-speaking students.  相似文献

RESUMEN

Se presenta una batería de evaluación de la percepción visual en la edad preescolar, momento clave para subsanar cualquier trastorno y valorar sus posibles incidencias en el aprendizaje de la lectoescritura. Basándose en los planteamientos con los que Frostig elaboró su test de desarrollo de la percepción visual se intentan evaluar las siguientes funciones: reconocimiento de la forma, distinción figura-fondo, orientación de un objeto en relación con el observador, transposición o reproducción de ángulos y líneas, y coordinación visomotora. A la vista de los resultados obtenidos en la aplicación de este test en una población escolar de 184 niños de párvulos y 93 del primer curso de EGB, se elaboran unos cuadros y gráficos de referencia y se describe el nivel de eficiencia y el rendimiento mínimo exigible en cada grupo de edad.  相似文献

This article explores the theory of action underlying New York University's (NYU's) Partnership Schools Program—explaining in the process what a theory of action is, and how it can be constructed for other innovations in other contexts. NYU's Partnership Program involves 23 schools, K-12, spanning several of New York City's most economically disadvantaged neighborhoods. It operates on the basis of what the authors call “mutual self-interest” and exploits what they call “complementarity.” The authors illuminate the program's original as well as its evolving intentions, and the environmental conditions necessary to enact them and to sustain the program over a decade. They also describe the program's core design elements, with a view to how these may be replicated elsewhere. Finally, they look closely at the Partnership's theory of action in action, employing action research data to portray a meeting where professors and teachers discuss the teacher education residency experiment they have collaboratively launched.  相似文献

A controversial issue in the field of language development is whether language emergence and growth is dependent solely on processes specifically tied to language or could also depend on basic cognitive processes that affect all aspects of cognitive competence (domain-general processes). The present article examines this issue using a large battery of infant information-processing measures of memory, representational competence, processing speed, and attention, many of which have been shown to predict general cognition in a cohort of full-terms and preterms. Results showed that various aspects of infant memory and representational competence (a) related to language at both 12 and 36 months, (b) predicted similarly for the two groups, and (c) predicted 36-month language, independently of birth status, 12-month language, and the 12-month Bayley Mental Development Index. Additionally, the results established predictive validity for the MacArthur 12-month language measure. These findings support a domain-general view of language.  相似文献

Purpose: The purpose of this study was to determine the extent to which a sport education season of fitness could provide students with recommended levels of in-class moderate-to-vigorous physical activity (MVPA) while also increasing students’ fitness knowledge and fitness achievement. Method: One hundred and sixty-six 5th-grade students (76 boys, 90 girls) participated in a 20-lesson season called “CrossFit Challenge” during a 4-week period. The Progressive Aerobic Cardiovascular Endurance Run, push-ups, and curl-ups tests of the FITNESSGRAM® were used to assess fitness at pretest and posttest, while fitness knowledge was assessed through a validated, grade-appropriate test of health-related fitness knowledge (HRF). Physical activity was measured with Actigraph GT3X triaxial accelerometers. Results: Results indicated a significant time effect for all fitness tests and the knowledge test. Across the entire season, the students spent an average of 54.5% of lesson time engaged in MVPA, irrespective of the type of lesson (instruction, free practice, or competition). Conclusions: The results suggest that configuring the key principles of sport education within a unit of fitness is an efficient model for providing students with the opportunity to improve fitness skill and HRF knowledge while attaining recommended levels of MVPA.  相似文献
