The novelty of three-dimensional visualization technology (3DVT), such as virtual reality (VR), has captured the interest of many educational institutions. This study’s objectives were to (1) assess how VR and physical models impact anatomy learning, (2) determine the effect of visuospatial ability on anatomy learning from VR and physical models, and (3) evaluate the impact of a VR familiarization phase on learning. This within-subjects, crossover study recruited 78 undergraduate students who studied anatomical structures at both physical and VR models and were tested on their knowledge immediately and 48 hours after learning. There were no significant differences in test scores between the two modalities on both testing days. After grouping participants on visuospatial ability, low visuospatial ability learners performed significantly worse on anatomy knowledge tests compared to their high visuospatial ability counterparts when learning from VR immediately (P = 0.001, d = 1.515) and over the long-term (P = 0.003, d = 1.279). In contrast, both low and high visuospatial ability groups performed similarly well when learning from the physical model and tested immediately after learning (P = 0.067) and over the long-term (P = 0.107). These results differ from current literature which indicates that learners with low visuospatial ability are aided by 3DVT. Familiarizing participants with VR before the learning phase had no impact on learning (P = 0.967). This study demonstrated that VR may be detrimental to low visuospatial ability students, whereas physical models may allow all students, regardless of their visuospatial abilities, to learn similarly well. 相似文献

By age 2, children are developing foundational language processing skills, such as quickly recognizing words and predicting words before they occur. How do these skills relate to children’s structural knowledge of vocabulary? Multiple aspects of language processing were simultaneously measured in a sample of 2-to-5-year-olds (N = 215): While older children were more fluent at recognizing words, at predicting words in a graded fashion, and at revising incorrect predictions, only revision was associated with concurrent vocabulary knowledge once age was accounted for. However, an exploratory longitudinal follow-up (N = 55) then found that word recognition and prediction skills were associated with rate of subsequent vocabulary development, but revision skills were not. We argue that prediction skills may facilitate language learning through enhancing processing speed. 相似文献

Visual‐perceptual difficulties and the impact on children's learning: are teachers missing the page?
This article attempts to bring to the fore of educational practice the importance of considering the visual‐perceptual condition of Meares–Irlen syndrome (MIS) when identifying students who have prolonged reading difficulties. Dyslexia is a frequently used term which can be used to label children who have specific difficulties with reading and/or spelling but this article discusses the problems that this may cause students who have a reading difficulty caused by a visual processing difficulty, as the working definitions of dyslexia do not, generally, consider this aspect as a factor, especially when remediation interventions are put forward. This article discusses the possibility that teachers and school psychologists may not be fully aware of MIS and therefore not able to recognise it. Moreover, if this condition is not adequately picked up at the important transition times in school then this could harm the student's self‐esteem and affect his or her motivation to succeed in school. The authors argue that the irony of MIS being potentially undetected by teachers and other school professionals is that it is relatively straightforward to identify, and in many cases, to correct. 相似文献

Malondialdehyde (MDA) is widely used as oxidative stress biomarker in biomedical research. Plasma is stored in deep freezers generally till analysis. Effect of such storage on MDA values, which may be variable and prolong, was incidentally observed in the ongoing study which is to estimate oxidative stress with oral iron. Plasma from blood samples of pregnant women (20–30 years age) in third trimester of singleton pregnancy (n = 139), consuming oral iron tablets was stored at −20 °C with intention of MDA estimation, as soon as possible. However logistic problems led this storage for prolonged and variable period (1–708 days). When values of MDA estimated using “Ohkawa” 79 method and readings were plotted against time to check the temporal effect, it showed a hyperbolic curve. Standard deviation (SD) was lowest when samples were tested within 3 weeks time. The samples analyzed within 3 weeks had mean ± SD value of 31.59 ± 26.11 μmol/L, while 123.7 ± 93.97 and 366.5 ± 189.8 μmol/L for samples stored for 1–3 and 4 months to 1 year respectively. Mean ± SD were 539.9 ± 196.8 in the samples store for more than a year. Rate of change in values was also lowest (0.0433 μmol/L/day) in the samples tested within first 3 weeks, which rose to 1.2 μmol/L/day during 3 month’s storage. This rate peaked at storage of 120 days (1.87 μmol/L/day) and fell to 0.502 μmol/L/day in the second year of storage. It is concluded that at −20 °C, only 3 weeks of storage time should be considered valid for fairly acceptable stability in MDA values. 相似文献

A longitudinal study was conducted to understand post‐school transition practice for young people with additional support needs (ASN) before and after the implementation of key legislation, the Education (Additional Support for Learning) (Scotland) Act 2004, amended in 2009. Primary data were collected from one local authority in Scotland. Twelve professionals involved in post‐school transition planning were interviewed in 2004 and eight in 2010. Minutes of transition meetings from one school for three young people prior to the implementation of the Act and four after the implementation were analysed. Results show some changes since the implementation of the Act. 相似文献

The present study investigated the antecedents and consequences of children’s math anxiety and math attitude. A total of 595 students aged 10 to 15 years (5th to 10th grades) and 1 parent of each (mother or father) participated in the study. The study was conducted in India, with the study sample drawn from schools in South-West Punjab. Math anxiety of parents and their children was measured using the Mathematics Anxiety Scale Short Version (MARS-SV), the Mathematics Anxiety Scale for Elementary School Students (MARS-E), and the Mathematics Anxiety Rating Scale for Adolescents (MARS-A). Math attitude was assessed with the Attitude Towards Mathematics Inventory (ATMI). A math achievement test was constructed for each grade level based on their curriculum. Path analyses were conducted to test the suggested conceptual model, and the results indicate that parental math anxiety and math attitude act as precursors to their children’s math anxiety and math attitude and further influence the math achievement of their children. 相似文献

Study was undertaken to assess thyroid status in hyperemesis gravidarum. 150 women pregnant with <20 weeks of gestation were
selected randomly and out of these 100 women presenting with hyperemesis formed study group while 50 normal pregnant women
served as controls. 53% of hyperemetic pregnant women were primigravidae and 82% of pregnant women presented with vomiting
at less than 12 weeks of gestation. Statistically significant, 22% of hyperemetic women had increased serum T3 levels while T4 levels were increased in 67% of women in study group as compared to 8% and 16% respectively in control group. TSH levels
were decreased in 18% of hyperemetic women as compared to 8% in control group with decrease in mean TSH level statistically
significant. 22% of hyperemetic women had electrolyte disturbances and 7% were ketonuric. In clinically euthyroid women, biochemically
altered thyroid function can attribute to vomiting and its prolongation to second trimester 相似文献

Insects like the grasshopper have developed different mechanisms to protect themselves from the chemical defenses of plants. During evolution, grasshoppers which showed no preference for a particular food, developed these for plants whose chemical defenses they could tolerate. 相似文献

With ever increasing information being available to the end users, search engines have become the most powerful tools for obtaining useful information scattered on the Web. However, it is very common that even most renowned search engines return result sets with not so useful pages to the user. Research on semantic search aims to improve traditional information search and retrieval methods where the basic relevance criteria rely primarily on the presence of query keywords within the returned pages. This work is an attempt to explore different relevancy ranking approaches based on semantics which are considered appropriate for the retrieval of relevant information. In this paper, various pilot projects and their corresponding outcomes have been investigated based on methodologies adopted and their most distinctive characteristics towards ranking. An overview of selected approaches and their comparison by means of the classification criteria has been presented. With the help of this comparison, some common concepts and outstanding features have been identified. 相似文献

ActionAid International implemented an action-research programme on women's unpaid care work in rural Nepal from March 2011 to December 2012. This social empowerment methodology, Reflect, enabled 106 women to gain recognition for their unpaid care work through their own collection of time-use data. The literacy skills women acquired facilitated greater representation in community meetings calling for a reduction in their unpaid care work rather than shifting this work to girls. The article draws on Fraser's model of gender justice to explore how women's literacy, girls’ education and a more equitable balance of care work are needed to improve women's status. 相似文献
