This paper assesses the relative contribution of maternal, household, child, and poverty characteristics to the quality of the home environment. The sample consists of 1,887 children birth to 4 years old from the National Longitudinal Survey of Youth (NLSY). Ordinary least-squares regression is used to explore conceptually distinct aspects of children's poverty experiences. Poverty variables are found to have a statistically significant effect on the quality of the home environment, after controlling for the effects of other variables in the models. Statistically significant interactions among poverty variables are identified. A major finding is that improvements in family income have the strongest effects on the quality of the home environment for children who were born poor or lived much of their lives in poverty. The conclusion emphasizes implications for future research.  相似文献

The paper contributes to design discourse by drawing on Educational Design Research (EDR) that has been conducted into what we call a Zone of Possibility (ZoP) over the past seven years. We define a ZoP as a place where individuals can overcome the constraints of expectations and power structures to effect desired change. Specifically, this paper presents details of how our initial research question (RQ1) has evolved to the one presented in the conclusions (RQ2); both RQs are summarised below in the section “Research Questions.” To describe this evolution, the paper is presented as 3 cases (Confer, ZoP Stokes Croft and Google Lens in HE) that have provided insights to explore the concept of the ZoP and its implications for EDR. Specifically, one of the main conclusions is the importance of bridging positioning practices as “successful communication” and an understanding of social context in hybrid contexts (ie, the ZoP).  相似文献

The Structure of Events and Event Representations: A Developmental Analysis   总被引:1,自引:0,他引:1  
In this study, we investigated how the temporal order and variability of events influence 3- and 5-year-old children's developing event representations. Children participated in 3 different events: a logical-invariant (making fundough), a logical-variable (shape collage), and an arbitrary-invariant (sand play) event. At each age, half of the children experienced the events once prior to recalling the events both verbally and behaviorally; the other half experienced the events 4 times, recalled the events verbally after each experience, and behaviorally reenacted the events only after the last experience. Children verbally recalled more and organized their recall better for the logical events than for the arbitrary event, and these differences remained stable with increasing experience. The sequencing of behavioral recall was also more accurate for the logical events than for the arbitrary event across age and condition, but amount of recall did not differ, with one exception. 3-year-old children in the single experience condition recalled less about the variable event than the invariant events. The results indicate that both the structure of the event and children's representational capabilities influence children's developing representations of events.  相似文献

Metacognition and EFL/ESL reading   总被引:6,自引:0,他引:6  
Several distinct research streams are converging in the field of foreign or second language reading in the U.S. Separate research streams in metacognition, in reading strategies, and in the training of reading strategies are converging in the field of English as a foreign or second language. This confluence of research is dramatically impacting the teaching of English to adult non-native speakers for academic purposes. In this article we will briefly review these distinct research streams for their relevance to the population in question, and will then describe the research design for an empirical study we are currently conducting to further investigate the efficacy of metacognitive strategy training for adult EFL/ESL reading.  相似文献

Animating the graphics in electronic documents may increase readers’ willingness to study them but may impair or distort the processes of gist comprehension. Experiment 1 confirmed that, compared with static diagrams, animation increased readers willingness to study a range of graphic genres (maps, time-lines, drawings of unfamiliar objects). Total reading time was also increased but readers’ differential access of static and animated graphics confounded the interpretation of immediate and delayed retention tests. Experiment 2 contrasted the effects of accessing the graphics before or during reading. Scores on a quiz immediately after reading were significantly higher when the graphics were seen before rather than during reading, suggesting that readers found it difficult to integrate the graphics while still building the gist of the text. Scores on both an immediate and a delayed quiz were significantly higher when the graphics were static rather than animated. One pointer to the cause of the decrement with animated graphics was that the quiz performance of readers having animated graphics correlated with their scores on a picture memory test, whereas those of readers with static graphics did not. In contrast the delayed quiz scores of readers with static graphics showed a significant interaction with their performance on a digit memory task. Readers with high scores on digit memory benefited from accessing the graphics while reading, but readers with low scores on the digit test were impaired by such access during reading. This suggests that the cognitive skills needed for integrating text with animated graphics may differ from those needed for dealing with static graphics.  相似文献

Purpose: Some adults with type 2 diabetes mellitus (T2DM) have comorbidities and mobility impairments that limit their exercise capacity. In consideration of this, we developed and piloted a program called Active Steps for Diabetes for people with T2DM, comorbidities, and mobility impairments. The purpose of this paper was to report outcomes for the pilot program. Methods: Active Steps for Diabetes, an 8-week program, included instruction on diabetes self-care andgroup and home exercise programs. Twenty-two females (62.7 ± 6.1yrs) with T2DM and self-reported mobility impairments completed the program. Six participants used a walking aid. Outcome measures included two risk factors for coronary artery disease [daily physical activity and body mass index (BMI)], cardiovascular fitness (6-minute walk distance), and knowledge of diabetes-specific exercise guidelines. A two-way repeated measures ANOVA was used to compare outcomes before and after the program and between participants who did and did not use a walking aid. Results: Active Steps for Diabetes was effective in increasing daily physical activity in both groups of subjects (walking aid group: 2.6 days/week [95% confidence interval (CI) = 2.1 to 3.3]; no walking aid group: 1.9 days/week [95% CI=1.2 to 2.5]). This was accompanied by increases in 6-minute walk distances (walking aid group: 54.0 m [95% CI = 36.4 to 71.6]; no walking aid group: 62.6 m [95% CI=55.7 to 69.4]). Changes in BMI were not significant (walking aid group: −0.4 [95% CI = −1.2 to 0.4]; no walking aid group: −.24[95% CI = −.91 to .44]). Increases in knowledge of diabetes-specific exercise guidelines were observed in both groups (walking aid group: 18.8% [95% CI = 11.3 to 26.4]; no walking aid group: 19.3% [95% CI = 16.1 to 22.5]). Discussion:: Physical inactivity and low cardiovascular fitness are predictors of CAD morbidity and mortality in adults with T2DM. This pilot program suggests that a model for diabetes education, incorporating exercise programs developed by a physical therapist, may increase physical activity, improve endurance, and thereby potentially reduce CAD risk in people with T2DM and mobility impairments from comorbidities.Key Words: type 2 diabetes, physical activity  相似文献

Nutrition plays an important role in the development of a child, particularly in low‐ and middle‐income countries where malnutrition is often widespread. The relation between diet, hemoglobin, nutritional status, motor development, stimulation and mental development was examined in a cross‐sectional sample of 1,079 children 12–18 months of age living in rural Bihar, India. Path analysis revealed associations between (a) length‐for‐age z‐scores and motor development, standardized β (β) = .285, p < .001, and (b) motor and all mental development outcomes (language: β = .422; personal‐social: β = .490; memory: β = .139; and executive function: β = .072, all p < .001). Additionally, stimulation was significantly associated with language scores and hemoglobin concentration with memory. These findings inform interventions aimed at improving child development in Northern India.  相似文献

The librarians of the Health Sciences Library worked with the director of the Primary Care Clerkship to reinforce the principles of Evidence-Based Medicine (EBM) searching, taught during the first two years of medical school, through an intensive workshop. The purpose of the program was to ensure that students apply EBM principles in a timely and effective manner in clinical situations. Working in teams led by a resident and librarian, students researched real cases and then evaluated the effectiveness of their approach to the problems. This paper outlines the rationale for the team approach, reviews the administration of a computer-based workshop, and discusses the evaluation process. Evaluation focused on both the current workshop and its implications for the informatics program presented to students during years one and two.  相似文献
