Carefully scaffolded dynamic visualizations have potential to promote science learning for all students, including English language learners (ELLs) who are often underserved in mainstream science classrooms, but little is known about how to design effective scaffolding to support such diverse students' learning with dynamic visualizations. This study investigated how two forms of scaffolding embedded in dynamic visualizations, expert guidance and generating guidance, can foster ELLs' and non-ELLs' understanding of unobservable scientific phenomena. While interacting with dynamic visualizations, students in the expert guidance condition were provided with scientifically accurate explanations to interpret visual representations, whereas students in the generating guidance condition were prompted to generate their own explanations using visual representations. The results show the significant advantage of generating guidance over expert guidance for both ELLs and non-ELLs, although students in the generating guidance condition did not receive feedback on their generated artifacts. Analyses of video data and log data from 40 pairs revealed that each form of scaffolding affected the quantity and quality of linguistically diverse students' conversations. The results show that generating guidance enabled students, particularly ELLs, to engage in discourse-rich practices to evaluate various sources of evidence from the visualization and compare the evidence to their alternative ideas to develop a coherent understanding of the target concepts. This study shows the unique benefits of generating guidance as an effective strategy to support linguistically diverse students' science learning with dynamic visualizations. 相似文献

Practicing engineers and undergraduate engineering and technology students seek and use information differently within the research and design process. This paper presents the results of a survey conducted by librarians at Purdue University and information specialists at Caterpillar Inc. to analyze self-reported information habits and challenges of both user populations. The authors created surveys containing similar questions for each user group, using a framework that asked participants to think about their information needs and use during a recent engineering project. The survey questions discerned users' confidence in their information abilities, and their preferences and barriers for finding and using information.The results of this study reveal differences between students and engineers and are informative for both academic and corporate librarians. Key findings affirm previous research that novices are more confident in their abilities than experts. Additionally, the findings suggest undergraduates prefer quick, easy to digest content like online videos and news, while engineers are more likely to learn by consulting a colleague or other subject expert, and through reading journals and trade literature. While students rated themselves as more confident information users, engineers reported working in a more complex information landscape, which includes internal document management systems and numerous places to look for technical information. Findings within this paper can inform the development of information literacy curricula that better parallels the corporate environment, and can give corporate librarians insight into how recent graduates may expect to interact with information in a new work environment. 相似文献

This paper explores one district’s attempt to implement a blended science and English Language Development (ELD) elementary
program, designed to provide English language learners opportunities to develop proficiency in English through participation
in inquiry-based science. This process resulted in blended program that utilized a combined science/ELD lesson plan format
to structure and guide teachers’ efforts to use science as the context for language development. Data, collected throughout
the first 2 years of the program, include teacher-generated lesson plans, observation notes, and interviews with teachers
and principals. The process by which the blended program was developed, the initial implementation of the program, the resulting
science/ELD lesson plan format, and teachers’ perceptions about the program and its impact on their students are described. 相似文献

There is limited published validity and reliability evidence to support using the Global Physical Activity Questionnaire. Two studies were conducted to evaluate validity and reliability evidence for the Global Physical Activity Questionnaire. In Study 1: 69 adults completed the Global Physical Activity Questionnaire (three months apart; n?=?54), International Physical Activity Questionnaire, fitness and anthropometric measures. All participants wore a pedometer and 53 participants wore an accelerometer for seven days at baseline. In Study 2, 16 adults completed the Global Physical Activity Questionnaire 10 days apart. Global Physical Activity Questionnaire moderate and vigorous minutes were correlated with the accelerometer moderate (r?=?0.28) and vigorous (r?=?0.48) physical activity. The Global Physical Activity Questionnaire and International Physical Activity Questionnaire were related for sedentary behaviors (r?=?0.51), moderate-to-vigorous (r?=?0.48) and vigorous (r?=?0.63) PA. Global Physical Activity Questionnaire moderate-to-vigorous physical activity was associated with percent fat (r =??0.32), estimated VO2 max (r?=?0.26), and step count (r?=?0.39). The Global Physical Activity Questionnaire demonstrated graded differences across categories for step count, body mass index, waist circumference, percent fat, fitness, and accelerometer measured activity. Short-term test–retest reliability (10 days) ranged from 0.83 to 0.96 while long-term reliability (three months) was 0.53 to 0.83. These data provide low-to-moderate validity and generally acceptable reliability evidence for the Global Physical Activity Questionnaire. 相似文献

The authors used realistic evaluation to examine the real-world effectiveness of two 5-day training techniques on sustained optimal skin-to-skin practices that support Step 4 of the revised Baby-Friendly Hospital Initiative (BFHI). The authors found that education alone was insufficient to effect sustainable practice change. Exposure to the 5-day immersion model (Practice, Reflection, Education and training, Combined with Ethnography for Sustainable Success, or PRECESS) alone or combined with education was an effective strategy to change and sustain the standard of care for skin-to-skin practice (p < 0.00001). The intended outcome of sustained practice change toward implementation of skin-to-skin care through immersion or a combined approach shows promise and should be repeated in other localities. 相似文献

Experiences of war and displacement can have profound effects on children's affective development and mental health, although the mechanism(s) underlying these effects remain unknown. This study investigated the link between early adversity and attention to affective stimuli using a free-viewing eye-tracking paradigm with Syrian refugee (n = 31, Mage = 9.55, 12 female) and Jordanian non-refugee (n = 55, Mage = 9.98, 30 female) children living in Jordan (March 2020). Questionnaires assessed PTSD, anxiety/depression, insecurity, distress, and trauma. Refugee children showed greater initial avoidance of angry and happy faces compared to non-refugee children, and higher trauma exposure was linked to increased sustained attention to angry stimuli. These findings suggest that war-related trauma may have differential effects on the early and later stages of affective processing in refugee children. 相似文献

Four‐ to 10‐year‐olds' and adults' (N = 263) ability to inhibit privileged knowledge and simulate a naïve perspective were examined. Participants viewed pictures that were then occluded aside from a small ambiguous part. They offered suggestions for how a naïve person might interpret the hidden pictures, as well as rated the probability that a naïve person would think of several different pictures (with one picture being the actual item). Results indicated a significant increase between ages 4 and 7 years in attributing novel interpretations; however, all age groups overestimated the probability that a naïve person could guess the actual pictures. Individual differences in working memory and inhibitory control predicted participants' thought suggestions as well as aspects of their probability judgments. 相似文献

Children adopted from institutions have been studied as models of the impact of stimulus deprivation on cognitive development (Nelson, Bos, Gunnar, & Sonuga‐Barke, 2011), but these children may also suffer from micronutrient deficiencies (Fuglestad et al., 2008). The contributions of iron deficiency (ID) and duration of deprivation on cognitive functioning in children adopted from institutions between 17 and 36 months of age were examined. ID was assessed in 55 children soon after adoption, and cognitive functioning was evaluated 11–14.6 months postadoption when the children averaged 37.4 months old (SD = 4.9). ID at adoption and longer duration of institutional care independently predicted lower IQ scores and executive function (EF) performance. IQ did not mediate the association between ID and EF. 相似文献

Society assigns professional educational programs the responsibility to aid students in learning and dedicate expert knowledge to furthering the well-being of citizens. This demand calls for addressing the how educational policies prioritize learning professionals' responsibility. Inspired by the theory of Jacques Derrida, we deconstruct the national curriculum text for Norwegian nursing education. Our findings indicate that, despite highlighting ethics and a holistic view on human beings, “hard evidence-based facts” remain the main navigation tool for responsible behavior. Additionally, by introducing “operational preparedness” as a learning goal, the texts partly renounce the obligation to educate for essential dimensions of responsibility by distributing the obligation to the future employer and the individual student. 相似文献

AbstractThis article pursues the question of what the significance was of the discursive construction of heroism for the National Socialist indoctrination of children in the context of communication processes at school. In particular, it is about ideological-educational intentions pursued in the context of teaching early readers as well as about topical foci and ways of communication. This is analysed by the example of reading primers. Based on the category-guided qualitative topical analysis of a representative body of 113 reading primers, the presentation of heroes as well as the constructs of heroic behaviour is worked out. 相似文献
