Commonly used early childhood curricula were examined to consider the degree to which they support research-based instruction for phonological awareness (PA) and phonics. A content analysis was completed for two types of curricula widely used in Head Start: overarching general curricula and lesson-based curricula, which usually provide more explicit teaching instructions. Both types of curriculum demonstrated the same pattern of findings; while all curricula included some content aligned with standards, programs differed greatly in the number of objectives and instructional strategies included for PA and phonics instruction. Overall, curricula were most likely to address earlier developing PA skills (e.g., rhyming, alliteration) with more limited attention to advanced skills that are closely linked with reading development (e.g., segmenting and blending of phonemes). Phonics instruction was not included often in any of the curricula studied, and opportunities for individualizing instruction were rare, particularly for children with special needs. Results suggest that instructional recommendations for PA and phonics in most of these commonly-used Head Start curricula, even those curricula which typically provide more explicit instruction for teachers, do not align with the instruction provided in effective intervention studies, and therefore may not be powerful enough to influence children’s reading trajectories. 相似文献

Biases against the elderly and people with disabilities can lead to discriminatory behaviors. One way to conceptualize attitudes toward the elderly and people with disabilities is through the differentiation of explicit (conscious) and implicit (unconscious) factors. Although both explicit and implicit attitudes and biases contribute to the full picture of peoples’ attitudes, explicit ideas alone may not accurately reflect people’s attitudes. This may be due to societal pressure to conceal explicit biases or the fact that often times, people are not aware they hold prejudiced views. The Implicit Association Test is a computer-based categorization task designed to assess implicit or unconscious attitudes. This test was used in in the current study to assess the impact of an intergenerational service-learning course. We designed this study to determine if greater exposure or contact with the elderly or people with disabilities might influence college students’ implicit attitudes. Pre- and post-assessment of participating students, using the Wilcoxon signed-rank test, found statistically significant decreased biases after participation. Results from this study that suggest participating in an intergenerational service-learning course can positively affect implicit attitudes. This is encouraging, especially because these attitudes are developed over a long period of repeated exposure, are consistently reinforced by cultural factors, and are notoriously difficult to change. 相似文献

Following landmark legislation passed more than 20 years ago, university–industry relationships have now become central to understanding the changing role of research universities in American Society. The paper analyzes the development of university–industry partnerships during the 1990s. Past studies have used a broad array of measures of ties and a variety of research methodologies, but they have shared a focus on top collaborators or on samples of universities skewed toward the top. However, findings based on top collaborators may not be valid for other universities. Universities involved in mid- to low-levels of collaboration are qualitatively different in many ways from the more extensively studied set of top collaborators, suggesting that characteristics affecting university–industry ties may not be the same for these institutions. The paper shifts the focus away from top collaborators to this sizable and less studied majority. In general, we find that the same characteristics predicting high levels of involvement for the sample as a whole also predict high levels of involvement for the sub-sample of mid- and low-level collaborators. However, We find some particular characteristics of these institutions, such as land grant status, are also associated with stronger ties to industry, and that some characteristics of 25 top institutions do not predict the level of involvement of these lower-level collaborators. We will discuss whether the licensing of new technology is likely ever to become an important source of net revenues for current middle and low-level collaborators. Our findings raise doubts about whether many universities below the top 25 will earn substantial net revenues from licensing, though they do not dispute the potential service value of these ties. The study is based on examination of a wide range of potential influences on university–industry collaboration for institutions that are not currently among the most heavily involved in partnerships. These include status, other institutional characteristics (such as size and control), investment in science and engineering, and characteristics of offices or technology transfer. 相似文献

Using a case study method, the experiences of a group of high school science teachers participating in a unique professional development method involving an argue-to-learn intervention were examined. The participants (N?=?42) represented 25 different high schools from a large urban school district in the southwestern United States. Data sources included a multiple-choice science content test and artifacts from a capstone argument project. Findings indicate although it was intended for the curriculum to be a robust and sufficient collection of evidence, participant groups were more likely to use the Web to find unique evidence than to they were to use the provided materials. Content knowledge increased, but an issue with teacher conceptions of primary data was identified, as none of the participants chose to use any of their experimental results in their final arguments. The results of this study reinforce multiple calls for science curricula that engage students (including teachers as students) in the manipulation and questioning of authentic data as a means to better understanding complex socioscientific issues and the nature of science. 相似文献

Although many studies have explored shared book reading between preschoolers and their families, very few have examined this practice within a large, nationally representative sample. Using the ECLS-B dataset, this study investigated shared reading among nearly 700 families of diverse ethnic, linguistic, and socioeconomic backgrounds. Coding of families’ book-related discussion focused on the variety of types of talk that parents used during reading. Results showed that parents focused primarily on the meaning of the story, with little attention to the code of the text. The range of talk techniques that parents used was largely independent of background factors such as child gender, ethnicity, or age, as well as family home language. A wider variety of meaning-related remarks by parents was linked to more advanced language skills among preschoolers. Findings provide a portrait of the nature of shared book reading discussion among American families, a profile of the background factors that are linked to this talk, and a precise account of the unique contributions of this talk to key emergent language and literacy competencies. 相似文献

In the present study, we examined the influence of kindergarten component skills on writing outcomes, both concurrently and longitudinally to first grade. Using data from 265 students, we investigated a model of writing development including attention regulation along with students’ reading, spelling, handwriting fluency, and oral language component skills. Results from structural equation modeling demonstrated that a model including attention was better fitting than a model with only language and literacy factors. Attention, a higher-order literacy factor related to reading and spelling proficiency, and automaticity in letter-writing were uniquely and positively related to compositional fluency in kindergarten. Attention and higher-order literacy factor were predictive of both composition quality and fluency in first grade, while oral language showed unique relations with first grade writing quality. Implications for writing development and instruction are discussed. 相似文献

Preschoolers’ (n?=?32) attention to print and pictures was documented during an electronic storybook reading session. Children (M?=?51.06 months; SD?=?7.34 months) looked at a 12-page book that contained three types of pages, each of which was presented four times over the course of the book: (1) silent presentation of print, (2) print that was read aloud, and (3) print that was both read aloud and highlighted. Our research objectives were to analyze whether the way in which print was presented related to the ways in which children attended to print and pictures during the reading session. Gaze fixation duration to print and pictures was assessed using a Tobii X2-60 portable eye tracking unit, which captured corneal reflection data for each child. Children’s total fixation duration to print was greatest when print was read aloud and highlighted as compared to when it was presented silently or read aloud. In addition, children looked at print more when it was displayed silently than when the computer read the story to children, although this difference was much smaller in magnitude. Children attended to pictures more than print across pages, but this difference was most notable when the story was read aloud. Results demonstrate the potential utility of nonverbal print referencing strategies during book reading. 相似文献

This study examined low-income, Spanish-speaking, immigrant Latina mothers' book sharing behaviors in relation to their children's vocabulary. Participants were 47 3-year-old children and their mothers. We addressed two research questions: (a) What interactive behaviors are evident when low-income immigrant Latina mothers and their 3-year-old children look at books together? (b) For these children and their mothers, which book-sharing behaviors are related to children's expressive language? Overall, our results indicated that mothers were involved in several kinds of interactions with the books. They enhanced their children's attention to the printed text, promoted interaction or conversation with their children about what was in the books, and somewhat less often, used more complex literacy strategies. Mothers who did these things most had children with the largest vocabularies even when mothers' vocabulary was taken into account. Implications for designing interventions for similar families are discussed. 相似文献

A mixed-methods study was undertaken with 118 biology students in two urban high schools. A Student-Centered Adaptable Learning Environment (SCALE) was created to improve engagement from affective and cognitive perspectives using choice, creativity and technological allowances. Results demonstrated that fast and slow learners are generally separated by about 30 min in terms of inputting speeds, but can be as much as 65 min apart from one another. Given that traditional classrooms afford students only 45 min in which to learn, static time could have become a source of inequity in public schools. SCALE optimally allowed for the dynamic use of time in constrained periods, therefore reducing and even eliminating any negative relationships between speed of learning and resultant achievement gains in the block setting. Especially benefitting from their ability to maneuver were the slowest learners, who showed the largest achievement improvements in either time interval amongst ability groupings. As learning speed can be the most critical contributing component of resultant educational outcomes, providing students the ability to use time dynamically should be considered as a feasible solution to helping teachers reestablish equity in mixed-ability classrooms in public schools. 相似文献
