When considering offering online education for engineering ethics instruction, making choices necessary for the effective
development and delivery of an engineering ethics curriculum is an important first step. Selecting the topics and types of
cases for the most effective ethics education of engineering students is a vital step in preparing an effective program. Examples
are presented for topics which are considered good candidates for online presentation, and the adaptability of these topics
for web-based instruction is discussed. Types of cases which are useful in engineering ethics education are presented. Methods
of teaching applied ethics, as well as ideas for web-based ethics course design are suggested. The market for web-based instruction
is discussed. 相似文献

The mechanisms used to convey parents' and teachers' educational expectations for the academic achievement of low-income African American children were explored using data from the Chicago Longitudinal Study. A total of 712 children were studied. A model of mediated effects was used to test the processes of influence from parents' and teachers' expectations to sixth-grade outcomes. Children's perceptions of expectations were hypothesized to mediate the effect of expectations to school outcomes. Study findings revealed that these perceptions only partially mediated the effects of expectations to sixth-grade reading and math outcomes, yet added unique independent variance to these outcomes. Prior achievement emerged as a powerful mediator of the effects of early educational intervention and sociodemographic variables to sixth-grade outcomes. These findings suggest a need to further investigate the processes of communicating parent and teacher expectations. 相似文献

Designing representative learning tasks is one means to enhance sports practice. Recent work has highlighted how the presence of situational information could help the design of these tasks by shaping intentions and enhancing the affective demands of practice, however this has yet to be empirically tested. This study tested this hypothesis by manipulating the presence of a scoreboard featuring time and score situational information as expert taekwondo athletes fought in practice. Nine taekwondo fighters fought with and without situational information in a counterbalanced order. Behaviour was assessed by tracking fighters' location coordinates to assess fighter-fighter dyad coordination and through notational analysis of attacking actions. Affect and cognition were assessed with mixed-methods that included perceptual scales measuring anxiety, arousal, mental effort, score perception, and post-fight video-facilitated confrontational interviews to explore how conditions differed. The results revealed that the presence of the situational information had significant effects on taekwondo players. When present, fighters reported greater cognitive anxiety (d = 0.39, p < 0.05), somatic anxiety (d = 1.11, p < 0.05) and emotion intensity (d = 0.33, p < 0.05). The enhanced affective demands were associated with behaviour changes that included fighters preferring to spend time at closer distances (d = 0.25, p < 0.05), and more predictable technique selection (d = 1.04, p < 0.05). Qualitative data supported these findings. Players also reported their intentions were coupled to the context of scoreboard. This study reveals that situational information changes the affective and behavioural demands of practice to be more like competition. Further, situational sampling affords performers the opportunity to practice attuning to the relevant affordances for a specific context. 相似文献

The present study aims to develop an integrative model that links neighborhood behavioral opportunities and social resources (neighborhood cohesion, neighborhood friendship and neighborhood attachment) to prosocial (sharing, helping, empathic) behavior in early adolescence, taking into account the potential mediating role of perceived support of friends. Path analysis was used to test the proposed theoretical model in a sample of 1,145 Italian early adolescents (6th through 8th graders). More perceived opportunities and social resources in the neighborhood are related to higher levels of adolescent prosocial behavior, and this relationship is partially mediated by perceived social support from friends. The results offer promising implications for future research and intervention programs that aim to modify social systems to improve child and adolescent social competencies. 相似文献

In their "The Prevalence of Mind-Body Dualism in Early China," Slingerland and Chudek use a statistical analysis of the early Chinese corpus to argue for Weak Folk Dualism (WFD). We raise three methodological objections to their analysis. First, the change over time that they find is largely driven by genre. Second, the operationalization of WFD is potentially misleading. And, third, dating the texts they use is extremely controversial. We conclude with some positive remarks. 相似文献

Oral narrative skills are assumed to develop through parent-child interactive routines. One such routine is shared reading. A causal link between shared reading and narrative knowledge, however, has not been clearly established. The current research tested whether an 8-week shared reading intervention enhanced the fictional narrative skills of children entering formal education. Dialogic reading, a shared reading activity that involves elaborative questioning techniques, was used to engage children in oral interaction during reading and to emphasize elements of story knowledge. Participants were 40 English-speaking 5- and 6-year-olds who were assigned to either the dialogic reading group or an alternative treatment group. Analysis of covariance results found that the dialogic reading children’s posttest narratives were significantly better on structure and context measures than those for the alternative treatment children, but results differed for produced or retold narratives. The dialogic reading children also showed expressive vocabulary gains. Overall, this study concretely determined that aspects of fictional narrative construction knowledge can be learned from interactive book reading. 相似文献

Marital conflict is a distressing context in which children must regulate their emotion and behavior; however, the associations between the multidimensionality of conflict and children’s regulatory processes need to be examined. The current study examined differences in children’s (N = 207, mean age = 8.02 years) emotions (mad, sad, scared, and happy) and behavioral strategies to regulate conflict exposure during resolved, unresolved, escalating, and child-rearing marital conflict vignettes. Children’s cortisol levels were assessed in relation to child-rearing and resolved conflict vignettes. Anger and sadness were associated with escalating and child-rearing conflicts, fearfulness was related to escalating and unresolved conflicts, and happiness was associated with resolution. Anger was associated with children’s strategies to stop conflict, whereas sadness was associated with monitoring and avoidant strategies. Cortisol recovery moderated the link between fearfulness and behavioral regulation. These results highlight the importance of children’s emotions and regulatory processes in understanding the impact of marital conflict. 相似文献

The European Clinical Specialization on Fluency Disorders (ECSF) project consists of one-year post-qualification fluency specialization training and a harmonized graduate fluency program. It was developed by eight European universities/colleges to provide the means whereby graduates would meet comparable standards of competence to practice in the field of fluency disorders. In this paper we describe criteria that guided the consortium in their decision making process to create an optimal learning environment for participants. A review of the first completed course cycle, with 23 international participants, is discussed.Educational objectives: After reading this article, the reader will be able to: (1) articulate the rationale for development of the ECSF-course; (2) summarize the content of both the harmonized undergraduate fluency course and the postgraduate fluency specialization course; (3) summarize the benefits of the suggested model for fluency specialization. 相似文献

Purpose
To find out what information children, parents and education staff feel would be important to know to support a child who stutters in the educational environment, in order to develop appropriate resources.Method
A Delphi study was carried out to seek the opinions of experts about the information to include. A structured six stage process was completed in order to gain consensus within four expert panels: children who stutter (CWS) aged 7-11 (n = 25); young people who stutter aged 12-18 (n = 27); parents of children and young people who stutter aged 2-18 (n = 67); and members of the education workforce (n = 35).Results
In response to the questions, 538 statements were generated across the four expert panels, categorised and reduced to 276. Of the 154 rating questionnaires sent out, 99 were returned (64.2% response rate). The top 32 statements, which were those most highly rated and with the greatest consensus, were retained to inform the resources.Conclusions
This study demonstrates the value of including service users when devising materials aimed for the benefit of CWS. The methodology employed ensured that ideas, perceptions and needs were representative of a range of people who experience stuttering from different perspectives. The results indicated that each expert panel had different priorities of what should be included. The resulting resources may therefore be considered to have high content validity and would be predicted to meet the needs of those who require them.Educational Objectives: The reader will be able to (1) define the Delphi Approach (2) discuss the development of a user led resource for raising awareness about stuttering. 相似文献130.
