These preliminary evaluation results suggest that the training approach is positively perceived by participants and that it has positive effects in changing their attitudes and behavior.  相似文献

Research on multimedia learning has shown that learning is hampered when a multimedia message includes extraneous information that is not relevant for the task, because processing the extraneous information uses up scarce attention and working memory resources. However, eye-tracking research suggests that task experience might be a boundary condition for this negative effect of extraneous information on learning, because people seem to learn to ignore task-irrelevant information over time. We therefore hypothesised that extraneous information might no longer hamper learning when it is present over a series of tasks, giving learners the chance to adapt their study strategy. This hypothesis was tested in three experiments. In experiments 1a/1b, participants learned the definitions of new words (from an artificial language) that denoted actions, with matching pictures (same action), mismatching pictures (another action), or without pictures. Mismatching pictures hampered learning compared with matching pictures. Experiment 2 showed that task experience may indeed be a boundary condition to this negative effect on learning: the initial negative effect was no longer present when learners gained experience with the task. This suggests that learners adapted their study strategy, ignoring the mismatching pictures. That hypothesis was tested in experiment 3, using eye tracking. Results showed that attention to the pictures waned with task experience, and that this decrease was stronger for mismatching than for matching pictures. Our findings demonstrate the importance of investigating multimedia effects over time and in relation to study strategies.  相似文献

Poor emotional competence has been identified as a precursor to later social, emotional, and behavioral difficulties in children. Aspects of parenting, including modeling, reactions to and coaching of children's emotions, have been associated with the development of emotional competence in children. In this paper, a parenting program with this theoretical basis is outlined and a pilot study of the program is presented. The six-session parenting program was delivered in preschool centers to 47 parents with a four or five year old child, and data were collected about parenting and children's functioning twice prior to program commencement, following program completion, and at three month follow-up. Pre and post program teacher assessments were also collected. Following the program parents reported that they were more encouraging of their children's emotional expression, used emotion-focused approaches more frequently in interactions with their children, and were less critical and dismissive of their children's emotional expression. Their children showed less emotional negativity and had significant reductions in difficult behaviors, especially those who had behavior problems prior to their parents' participation in the program. This program offers a promising approach to fostering the development of children's emotional competence and consequently enhancing social and behavioral functioning.  相似文献

This paper reports on school readiness (SR) and its predictors in five‐ to six‐year‐old children from a prospective, longitudinal study of children from eight months to seven years (the Early Language in Victoria Study – ELVS). The ELVS children came from a representative sample of children recruited though the State Government Infant and Child Health Centres at the age of eight months who were studied at yearly intervals with a combination of parent surveys and face‐to‐face assessments. The study had a focus on language, pre‐literacy and behavioural development. In pre‐school and preparatory grade, teachers of the children completed a brief questionnaire rating SR characteristics, including cognitive, language and personal/social competencies. The data bank on these children provided a set of hypothesised child and family predictors of the SR score which were tested via factor analysis and regression analyses. Significant predictors of SR in the equation were evident from two years of age, and were all related to language and pre‐literacy factors from two to six years. Twelve per cent of the children showed language impairment (LI) at five years according to their scores on the Clinical Evaluation of Language Fundamentals, 4th edition (CELF‐4). In an additional analysis we found that these children were significantly lower on SR; they were also of lower social class compared with the remainder of the sample. The most influential factors in readiness for school were child language competencies and pre‐literacy capacities, including phonemic awareness and letter knowledge. Preparation for school involving systematic emphasis on language and pre‐literacy enrichment is recommended for all children before school entry and particularly for children at risk, including those coming from socio‐economic disadvantage and those with delayed and impaired early language development. This addition to pre‐school programmes can have lasting positive effects into pre‐school and beyond, and prevent early school failure.  相似文献

Abundant U.S. research documents an “immigrant advantage” in children’s physical health. This article extends consideration to the United Kingdom, permitting examination of a broader group of immigrants from disparate regions of the world and different socioeconomic backgrounds. Drawing on birth cohort data (ages 0–5) from both countries (n = 4,139 and n = 13,381), the analysis considers whether the children of immigrants have a physical and mental health advantage around the beginning of elementary school, and whether advantage is more pronounced among low‐educated populations. Findings indicate that the children of immigrants are not uniformly healthier than those in native‐born families. Rather, there is heterogeneity in the immigrant advantage across outcomes, and evidence of both greater advantage and disadvantage among children in low‐educated immigrant families.  相似文献

This study investigates the physiological responses to upwind sailing on a laser emulation ergometer and analyses the components of the physical profile that determine the physiological responses related to sailing level. Ten male high-level laser sailors performed an upwind sailing test, incremental cycling test and quadriceps strength test. During the upwind sailing test, heart rate (HR), oxygen uptake, ventilation, respiratory exchange ratio, rating of perceived exertion (RPE) and lactate concentration were measured, combined with near-infrared spectroscopy (NIRS) and electromyography (EMG) registration of the M. Vastus lateralis. Repeated measures ANOVA showed for the cardio-respiratory, metabolic and muscles responses (mean power frequency [MPF], root mean square [RMS], deoxy[Hb+Mb]) during the upwind sailing test an initial significant increase followed by a stabilisation, despite a constant increase in RPE. Stepwise regression analysis showed that better sailing level was for 46.5% predicted by lower MPF decrease. Lower MPF decrease was for 57.8% predicted by a higher maximal isometric quadriceps strength. In conclusion, this study indicates that higher sailing level was mainly determined by a lower rate of neuromuscular fatigue during the upwind sailing test (as indicated by MPF decrease). Additionally, the level of neuromuscular fatigue was mainly determined by higher maximal isometric quadriceps strength stressing the importance of resistance training in the planning of training.  相似文献

Many students in Britain, especially those training for the professions, do parts of their courses in the form of placements in the field. Most such placements are compulsory. During placements students are the joint concern of their tutors on the campus and their mentors in the field. The placements on the different courses seem dramatically different. For example, some placements are in primary schools, some in hospital wards, some in factory pharmacies and some in electrical power stations. This study shows, however, that despite such obvious differences in the placement settings, student feelings about placement can be remarkably similar. For staff whose courses include placement there are issues which they could usefully discuss in common.  相似文献
