In this paper, we examine the meaning of conversing with pedagogical agents. Previous research has focused on examining cause and effect relationships, failing to take into account the meaning of the experiences individuals have when holding a dialogue with conversational agents for educational purposes. To understand these experiences, we have conducted a phenomenological examination of what it means to converse with a pedagogical agent. In phenomenological terms, findings suggest the experience is complex, engrossing, virtual yet real, human‐like, and social. Implications for the future design, implementation, and research of conversational agents in educational and other settings are discussed.  相似文献

International and interdisciplinary literature on cross-racial friendships is critically reviewed as a source of relevant and provocative data for counselling professionals dedicated to multiculturalism. The authors discuss the dynamics of cross-racial friendships and implications for counsellors. Using practical examples grounded by interdisciplinary literature, the authors expand discussions about racism within the counselling profession.  相似文献

This paper presents a study that used newly developed instruments to investigate student expectations at two points in a semester‐based course. Course convenors were able to make some changes in response to the feedback, explain to students how the feedback had informed the course processes, and work with tutors on delivery enhancements. The administration of these instruments, a partnership approach involving students, tutors and lecturers, contributed to the creation of a responsive teaching and learning environment. In addition to enabling real‐time changes to be made, evaluation of the total teaching and learning experience ensured that improvements were made to subsequent offerings of the same course. Also, insights from one course were evaluated in terms of applicability to other courses offered within the same academic discipline. The study finds that establishing student expectations provides a framework for developing a responsive and iterative approach to achieving excellence in teaching and learning.  相似文献

Typical university‐wide course evaluations do not provide instructors with sufficient information on the effectiveness of their courses. This article describes a course assessment and enhancement model where student feedback can be used to improve courses and/or programs. The model employs an assessment tool that measures student perceptions of importance and their current competence in course‐specific learning objectives both pre‐ and post‐course. Information gained from this assessment enables course improvement over time and also allows for modification in delivery and/or content of the current course. This model is intended to augment traditional course evaluation mechanisms based on specific and actionable feedback on learning objectives.  相似文献

Through selected theories of melancholia, this paper seeks to shed some fresh interpretive light on the reproduction and disruption of gender, violence and family turmoil across generations of mothers and daughters. The originality of the paper lies in its exploratory deployment of theories of melancholia to consider issues of women, violence and generation. It addresses these matters through a discussion of the intergenerational emotional archives accumulated by two mother–daughter pairs in relation to their different experiences of sexual and other violence. It shares the mothers’ experiences of violence in their childhood and shows how these help to shape the ways in which they raise their daughters and address the troubles that their daughters experience. Different theories of melancholia assist us to explain the dissimilar emotional dynamics between these mother and daughter pairs. But equally their stories suggest the analytical potential of different theories of melancholia for understanding women’s and girls’ diverse responses to violence. Freud’s, Irigaray’s and Silverman’s constructions of melancholia, which are to some extent based on notions of emptiness, lack and insufficiency, are deployed alongside Eng and Kazanjian’s interpretation of a melancholic state of being which focuses on the creative potential of animating the remains of loss; an interpretation that invokes an agential relationship to the losses that violence provokes. The former help to explain what Eng and Kazanjian might see as the ‘hopeless politics’ associated with certain melancholic responses to violence and the latter help to explain what they might consider more ‘hopeful politics’ associated with responses that mobilise a more agential relationship to loss. Although not subscribing to such a stark binary interpretation, we nonetheless argue for an analysis that acknowledges the different ways that the remains of loss are animated. The paper arises from a wider cross‐generational study in Australia of the lives of educationally, economically and culturally marginalised young women and their mothers.  相似文献

The purpose of this viewpoint is to consider the impact of the current Covid-19 crisis on the educational prospects of young children attending early childhood education and care (ECEC) settings. Studies show that health pandemics and environmental, political, and socio-economic crises jeopardize children’s development and education. It is likely that for the immediate future, young children will continue to experience emotional and psychological stress. A curriculum that does not take into consideration a pandemic of the scale we are witnessing today creates unnecessary pressure and anxiety not just on young children but also on the adults who care for and teach them. This article outlines actions to ensure quality education for all as suggested by the United Nations Sustainable Development Goals. The response of ECEC curricula to the pandemic may potentially act as a catalyst for educational change.

Traditionally colleges have relied on standalone non-credit-bearing developmental education (DE) to support students academically and ensure readiness for college-level courses. As emerging evidence has raised concerns about the effectiveness of DE courses, colleges and states have been experimenting with approaches that place students into credit-bearing coursework more quickly. To better understand which types of students might be most likely to benefit from being placed into college-level math coursework, this study examines heterogeneity in the causal effects of placement into college-level courses using a regression discontinuity design and administrative data from the state of Texas. We focus on student characteristics that are related to academic preparation or might signal a student’s likelihood of success or need for additional support and might therefore be factors considered for placement into college-level courses under “holistic advising” or “multiple measures” initiatives. We find heterogeneity in outcomes for many of the measures we examined. Students who declared an academic major designation, had bachelor’s degree aspirations, tested below college readiness on multiple subjects, were designated as Limited English Proficiency (LEP), and/or were economically disadvantaged status were more likely to benefit from placement into college-level math. Part-time enrollment or being over the age of 21 were associated with reduced benefits from placement into college-level math. We do not find any heterogeneity in outcomes for our high school achievement measure, three or more years of math taken in high school.

Oral Cancer is one of the five leading sites of cancer in Indian population. The circulating immune complexes were investigated in 100 serum samples of 60 oral cancer patients having different grades of the disease and 40 patients with precancerous lesions obtained from Nair Hospital Dental collage, Mumbai. The results obtained were compared with those of group of 40 healthy blood donors. Elevated levels of Circulating Immune Complexes were observed in oral cancer patients and patients with oral precancerous lesions. 92% positive samples were observed in well differentiated squamous cell carcinoma whereas 100% positive samples were observed in both moderately and poorly differentiated squamous cell carcinoma. Oral leukoplakia and oral submucous fibrosis showed 15% and 90% positivity respectively. Increased level of Circulating Immune complexes in high grade tumor suggest that Circulating Immune complexes is likely to contribute in evaluating the degree of malignancy, but follow up study is needed to draw any conclusion regarding it's prognostic role  相似文献

Structured document retrieval makes use of document components as the basis of the retrieval process, rather than complete documents. The inherent relationships between these components make it vital to support users’ natural browsing behaviour in order to offer effective and efficient access to structured documents. This paper examines the concept of best entry points, which are document components from which the user can browse to obtain optimal access to relevant document components. It investigates at the types of best entry points in structured document retrieval, and their usage and effectiveness in real information search tasks.  相似文献
