This study examined the contribution of situational probability information to the perceptual and cognitive processes underlying decision-making behaviour during in situ Karate performance. Experts and novices were required to make decisions about various attacks in different fight scenarios. The order in which the fight situations were presented was modified in order to provide advanced probability information and identify whether fighters were able to use the latter information to make better decisions. Specifically, one of the attacks was repeated every four actions. Results revealed that experts were more accurate and faster than their less skilled counterparts to block and counterattack the opponent. The experts picked up the occurrence of the attack pattern after the fifth repetition whereas novices did not. This enabled experts to improve decision time and decision accuracy. Findings suggest that such superiority could stem from the perceptual and cognitive skills possessed by the experts, thus giving them the opportunity to recognise a situation more easily. This was reinforced by gaze behaviour which demonstrated that experts used a more efficient search strategy involving fewer fixations of longer duration on a lesser number of areas relative to the novices. Moreover, experts generated more refined karate-specific knowledge structures compared with the novices. 相似文献

Purpose
The study evaluates how providers give patient education materials and identifies improvements to comply with Meaningful Use (MU) requirements.Methods
Thirty-eight patient-provider interactions in two health care outpatient clinics were observed.Results
Providers do not uniformly know MU patient education requirements. Providers have individual preferences and find gaps in what is available. Accessing and documenting patient education varies among providers. Embedded electronic health record (EHR) materials, while available, have technical access barriers.Conclusions
Providers'' EHR skills and knowledge levels contribute to non-standardized patient education delivery. 相似文献33.
This research examines 441 front-page images published in 367 newspapers on the day following the shooting in Paris of 12 people at or near the Charlie Hebdo office. The aim of this study is to understand how mainstream media visually framed responsibility for the Charlie Hebdo massacre and how these visual frames coalesced to represent collective narratives about press freedom. Through a collaborative visual analysis, this study attempts to understand how the selected visual frames worked to communicate the causes, effects, and responses to the massacre and also to press freedom—an ideological construct that news media had a vested interest in advancing. 相似文献

Estimating the number of glacial advances from surviving glacial debris can, amazingly enough, be cast as a records problem for which there is a substantial statistical literature. As a result, instructors may illustrate method of moments and maximum‐likelihood estimation techniques with an interesting problem in the physical sciences. 相似文献

ABSTRACT Nursing Assistants (NAs) are the largest workforce in nursing homes, but often lack adequate preparation for their role. The Living Classroom (LC) is an integrated learning approach, whereby a NA program is delivered in a nursing home (NH) in collaboration with a community college. This paper describes the implementation and evaluation of the LC. Mixed methods were used to gather data from 48 NA students, 5 faculty, and 42 NH staff over 30 weeks. Students, faculty, and nursing home staff described the LC as a positive learning experience. Students’ gerontological knowledge increased over time (p = .0012). Students reported very positive relationships with program mentors and NH residents. The LC provides a unique approach to prepare NAs to work in nursing homes. This model could expand to other educational programs with a gerontology focus. 相似文献

Conclusions As the pilot project has only been in operation for one semester there are no profound statements that can be made. What we
have at present is the base information for comparison of all data over the duration of the project. Cross tabulation of the
data to date has begun. However it should be re-iterated here that there appears to be a lack of understanding by the parents'
as to the reason for the all-girls classes at the school and that this situation may be due to the fact that in this school
community we have the typical sex-stereotyping roles and attitudes existing. The big question is, Will this intervention strategy
of single-sex science classes be effective in altering the girls views about what is appropriate for them to study or follow
as a career? 相似文献

Two cohorts of children from inner-city elementary schools were provided a tutoring intervention to help in their transition to new schools. Participants were third, fourth, and fifth grade children who were identified as having low-income status, evidencing lags on achievement tests, and experiencing stressful life events. The intervention involved an orientation program with twice weekly paraprofessional tutoring. Two and three year academic and sociometric follow-up data were collected. Those provided the intervention evidenced some improvements over time, and these changes were most prominent in the area of reading grades. Fewer significant findings were found on sociometric indices. 相似文献

To assess the impact of a holistic career and life planning course on college students, the authors asked 209 students in treatment and control groups to complete measures of career development. Results indicate that the course significantly increases vocational identity and career decision‐making self‐efficacy and decreases career indecision. 相似文献

The purpose of this study was to investigate the impact of imagery interventions on the vocabulary acquisition abilities of
second grade students. A total of 15 students were randomly assigned to three different intervention conditions: Word Only,
which involves the simple verbal presentation of a vocabulary word; Dual Coding, in which a picture was paired with the vocabulary
word, and Image Creation, in which students were told to create a mental picture of the vocabulary word in their mind and
draw it on paper. These students were taught a total of 21 vocabulary words: seven animal and habitat words, seven musical
instrument terms, and seven science terms. A Latin square design was used, in which each group of students rotated through
each of the interventions, being exposed to a different treatment condition for each category of words. Participants were
measured on the number of words they were successfully able to acquire through the use of experimenter designed comprehension
measures. While no statistical significance was shown between the interventions across the word categories, a significant
difference was found between the Image Creation and Word Only interventions within the science terms category. Students also
reported that the imagery interventions facilitated the ease with which they learned the words. The findings have implications
for increasing the success of classroom instruction, specifically for presenting novel vocabulary words to early elementary
learners using imagery methods. 相似文献
