We examined the degree to which content of states’ writing standards and assessments (using measures of content range, frequency, balance, and cognitive complexity) and their alignment were related to student writing achievement on the 2007 National Assessment of Educational Progress (NAEP), while controlling for student, school, and state characteristics. We found student demographic characteristics had the largest effect on between-state differences in writing performance, followed by state policy-related variables, then state and school covariates. States with writing tests that exhibited greater alignment with the NAEP writing assessment demonstrated significantly higher writing scores. We discuss plausible implications of these findings. 相似文献

To investigate alternation behavior in the cockroach as an invertebrate, three T-maze experiments were conducted assessing the effects of (a) intratrial (exposure) and intertrial (exposure to test) interval, (b) brightness similarity of the alternatives and response-direction factors, and (c) an initial free-choice vs. a varying number of forced-choice exposures. Alternation was enhanced with a long exposure on Trial 1, a short interval between Trial 1 and Trial 2 (test), greater dissimilarity (or discriminability) of the arm brightnesses and more frequent forced-choice exposures to an arm prior to test. These results highlight the role of intramaze brightness cues as controlling alternation in the cockroach and accord well with a response-to-change interpretation of the phenomenon. In addition, they suggest that the alternation paradigm can be used effectively to assay short-term memory storage in neurologically simple organisms. 相似文献

This project developed and studied The Source, an alternate reality game (ARG) designed to foster interest and knowledge related to science, technology, engineering, and math (STEM) among youth from populations underrepresented in STEM fields. ARGs are multiplayer games that engage participants across several media such as shared websites, social media, personal communications, and real-world settings to complete activities and collaborate with team members. The Source was a five-week summer program with 144 participants from Chicago aged 13 to 18 years. The Source incorporated six socio-contextual factors derived from three frameworks: Chang’s (ERIC Digest, 2002) recommendations for engaging underrepresented populations in STEM careers, Lave and Wenger’s (Cambridge University Press, 1991) situated learning model, and Barron’s (Human Development, 49(4); 193-224, 2006) learning ecology perspective. These factors aligned with the program’s aims of promoting (1) social community and peer support, (2) collaboration and teamwork, (3) real-world relevance and investigative learning, (4) mentoring and exposure to STEM professionals, (5) hands-on activities to foster transferable skill building, and (6) interface with technology. This paper presents results from 10 focus groups and 10 individual interviews conducted with a subset of the 144 youth participants who completed the game. It describes how these six factors were realized through The Source and uses them as a lens for considering how The Source functioned pedagogically. Qualitative findings describe youth’s perception of The Source’s potential influence on STEM interest, engagement, and identity formation. Despite limitations, study results indicate that underrepresented youth can engage in an immersive, narrative, and game-based experience as a potential mechanism for piquing and developing STEM interest and skills, particularly among underrepresented youth. 相似文献

AbstractEducational policy changes are intertwined with teacher education at multiple levels, affecting teacher educators in a variety of ways. Despite the different contexts, teacher educators in the United States and India must fulfill a variety of roles in order to meet the demands within those contexts. This qualitative study compared the cases of seven teacher educators in Iowa in the United States and seven teacher educators in Delhi, India on their common experience of mandated policy changes. Collaboration was found to be central in the teacher education policy implementation process in Iowa, USA and Delhi, India. 相似文献

Electric shocks were delivered to rats through a subcutaneously implanted back electrode. Experiment 1 evaluated the relationship between number of paws grounded and total power dissipated in the rat. In Experiment 2, the threshold of shock-induced vocalization, a putative index of aversiveness, was found to be positively correlated with the number of paws grounded. These findings suggest that when the backshock technique is used, the aversiveness of shock potentially can be modified by the posture adopted by the experimental animal. Caution should be exercised, therefore, in attributing deficits in escape behavior following inescapable shock administered with back electrodes to learned helplessness. 相似文献

AbstractThis paper offers a strategic initiative designed to boost the level of collaborative mathematical research involving undergraduate mathematics students at Butler University. It describes goals, program design, logistics, and outcomes for an 8-day intensive summer experience in which undergraduate mathematics majors engaged in original mathematical research at an introductory level. 相似文献

Autonomy operates as a key term in debates about the rights of families to choose distinct approaches to education. Yet, what autonomy means is often complicated by the actual circumstances and contexts of schools, families, and children. In this essay, Terri S. Wilson and Matthew A. Ryg focus on the challenges involved in translating an ideal of educational autonomy into the “nonideal” contexts and circumstances that surround families' choices. Drawing on the methodological insights of Elizabeth Anderson and John Dewey, they sketch out a nonideal approach for exploring autonomy. Wilson and Ryg particularly focus on Dewey's notion of an ideal, his treatment of autonomy as a concept, and his view of the self. Such a nonideal approach draws attention toward the specific circumstances, habits, and environments that make autonomy possible. Wilson and Ryg illustrate the salience of this nonideal approach by exploring one example of an empirically engaged study of autonomy. 相似文献

van der Goot et al. (2014) proposed that distal, deictic communication indexed the appreciation of the psychological state of a common ground between a signaler and a receiver. In their study, great apes did not signal distally, which they construed as evidence for the human uniqueness of a sense of common ground. This study exposed 166 chimpanzees to food and an experimenter, at an angular displacement, to ask, “Do chimpanzees display distal communication?” Apes were categorized as (a) proximal or (b) distal signalers on each of four trials. The number of chimpanzees who communicated proximally did not statistically differ from the number who signaled distally. Therefore, contrary to the claim by van der Goot et al., apes do communicate distally. 相似文献

La pregunta que se plantea el titular de este artículo no es sino una de entre las muchas que se plantean a lo largo del texto acerca de los protagonistas, los contextos y los recursos que pueden ponerse en marcha en un futuro ya presente, al menos en las sociedades avanzadas. Se pasa revista desde el modelo de aula que se avecina, a las nuevas tecnologías—el ordenador y su software, pero también los audiovisuales o el propio texto escrito—, hasta el modelo de profesor y de relación educativa que implican esos nuevos contextos. 相似文献
