This paper reports on an investigation into how staff teaching in compressed courses can encourage student engagement and enhance student use of learning time, despite significant restraints of time as well as distance. Typically these courses (described here as units) are expected to have comparable learning outcomes to their full-semester counterparts and provide an opportunity for students to either retake failed units or to acquire credit for their chosen degrees in accelerated time. Organising teaching and learning through intensive modes of delivery may require different approaches to curriculum development and pedagogy compared to traditional unit planning and delivery, especially when the intensive delivery utilises online technologies. This paper explores strategies employed by successful intensive mode teachers in the development and delivery units for maximised student engagement. It concludes that many of these strategies are equally applicable in online and distance education regardless of the unit being intensive or otherwise. 相似文献

This investigation examined orthographic and semantic processing during reading acquisition. Children in first to fourth grade were presented with a target word and two response alternatives, and were asked to identify the semantic match. Words were presented in four conditions: an exact match and unrelated foil (STONE–STONE–EARS), an exact match and an orthographic neighbour foil (STONE–STONE–STOVE), a synonym match and an unrelated foil (STONE–ROCK–EARS) and a synonym match and an orthographic neighbour foil (STONE–ROCK–STOVE). Accuracy and reaction time results suggest that orthographic and semantic processing follow a two‐step acquisition pattern. First, the orthographic component of reading develops quickly; however, forming strong conceptual links from orthographic to semantic representations follows a protracted trajectory, which matures between the third and fourth grades. These results are consistent with research that suggests younger children rely on more concrete, perceptual systems and then transition to more flexible, abstract cognition. 相似文献

This article exposes the ancient Nepohualtzitzin as an important contemporary mathematical tool. The design and development of Nepohualtzitzin Ethnomathematics Clubs (NECs) in predominantly Latina/o and low-income schools is also presented. NECs provide informal learning opportunities to develop and strengthen cultural connections to and abilities in mathematics for bicultural-bilingual learners, their parents, and teacher candidates. The formation of NECs is made possible through transnational alliances developed over time between the University of Texas at San Antonio, Secretaría de Educación Pública de México (Ministry of Public Education of Mexico), Coahuiltecan Indian Nation, Aztlán Associates, Danza Azteca Xinachtli, and Tzicatl—Community Development Corporation. 相似文献

The understanding of swimming propulsion is a key factor in the improvement of performance in this sport. Propulsive forces have been quantified under steady conditions since the 1970s, but actual swimming involves unsteady conditions. Thus, the purpose of the present article was to review the effects of unsteady conditions on swimming propulsion based on studies that have compared steady and unsteady conditions while exploring their methods, their limitations and their results, as well as encouraging new studies based on the findings of this systematic review. A multiple database search was performed, and only those studies that met all eligibility criteria were included. Six studies that compared steady and unsteady conditions using physical experiments or numerical simulations were selected. The selected studies verified the effects of one or more factors that characterise a condition as unsteady on the propulsive forces. Consequently, much research is necessary to understand the effect of each individual variable that characterises a condition as unsteady on swimming propulsion, as well as the effects of these variables as a whole on swimming propulsion. 相似文献

Children of depressed mothers are at risk for behavioral and emotional problems. Infants of depressed mothers exhibit behavioral disturbances and atypical frontal brain activity. The mechanisms by which children develop such vulnerabilities are not clear. Three-year-old children of mothers with (N = 65) and without (N = 59) a history of depression were assessed in terms of behavior problems and brain electrical activity. Children of mothers with chronic depression exhibited lower frontal and parietal brain activation compared with children of mothers without depression and those whose depression remitted. Depressed mothers reported higher contextual risk (e.g., marital discord and stress) and their children had more behavior problems. Children's frontal brain activation and contextual risk level mediated the relation between maternal depression and child behavior problems. 相似文献

The theme of SME marketing networks acquires high relevance because of their positive influence over internationalization and market competitiveness. Within this stream of research, how partners learn to implement and manage collaborations has received little attention. This article aims to bridge this gap, first, by analysing the mechanisms partners use throughout their learning process, and, second, by investigating whether this learning process may have an association with the network ability to explore new market opportunities, which is the ultimate objective of SMEs willing to overcome the liability of smallness. The results of this article unveils the different structures, processes and tools, which are used to create new knowledge on how to implement and manage SME marketing networks; furthermore, it suggests that an effective learning process may have a positive association with the exploration of new market opportunities through networks. 相似文献

Suicide is among the main causes of death of people aged between 15 and 44 years old. Childhood trauma is an important risk factor for suicide. Hence, the objective of this study was to verify the relationship between childhood trauma and current suicide risk (suicidal behavior and ideation) in individuals aged 14–35 years, in the city of Pelotas, Brazil. This is a cross-sectional, population-based study. Sample selection was performed by clusters. Suicide risk was evaluated using the Mini International Neuropsychiatric Interview (MINI) and Childhood trauma was assessed with the Childhood Trauma Questionnaire (CTQ). Moreover, the participants responded to a questionnaire concerning socioeconomic status, work, and substance use. The sample was composed of 1,380 individuals. The prevalence of suicide risk was 11.5%. The prevalence figures of childhood trauma were 15.2% (emotional neglect), 13.5% (physical neglect), 7.6% (sexual abuse), 10.1% (physical abuse), and 13.8% (emotional abuse). Suicide risk was associated (p < .001) with gender, work, alcohol abuse, tobacco use, and all types of childhood trauma. The odds of suicide risk were higher in women (OR = 1.8), people who were not currently working (OR = 2.3), individuals who presented alcohol abuse (OR = 2.6), and among tobacco smokers (OR = 3.4). Moreover, suicide risk was increased in all types of trauma: emotional neglect (OR = 3.7), physical neglect (OR = 2.8), sexual abuse (OR = 3.4), physical abuse (OR = 3.1), and emotional abuse (OR = 6.6). Thus, preventing early trauma may reduce suicide risk in young individuals. 相似文献
