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
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
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.
Although mounting evidence in Western nations indicates that entertainment media influence young people’s sexual socialisation, virtually no research has addressed the topic in sub-Saharan Africa. The present study employed 14 focus groups of Ugandan high school students to identify media through which they were exposed to sexual content, how they interpreted and evaluated that content, and how they compared its influence with that of parents, schools and religious institutions. Participants most often mentioned TV, followed by print media and Internet as sources of sexual material. Media were said to present discrepant messages regarding the timing of sexual debut, with international programming urging early sexual debut and local programming described as urging young people to delay sex. Young people spoke of turning to ssengas and kojjas for sexual advice, and a number of boys suggested pornography could also be educational. Both local and international programming was interpreted as conveying views of men as sex driven and women as submissive in sex and relationships. Participants expressed the belief that sexual media content had a negative impact on young people. Most nevertheless assessed these messages as more influential than other sources of sexual socialisation. 相似文献
Changes in affect toward a particular stimulus can take place very rapidly through Pavlovian conditioning, if presentation of the conditioned stimulus (CS+) paired with the unconditioned stimulus (US) is accompanied by presentation of a “CS?,” another value of the same dimension as the CS+ but not paired with a US. This effect has considerable generality. It has been observed in terms of both olfactory and visual CSs, in terms of appetitive as well as aversive conditioning, and for adult as well as infant rats. The CS? effect has seemed especially important for infants, which may be related to the general tendency for infants to exhibit less stimulus selection than older animals. Finally, the CS? effect has enabled the development of a simple test of short-term retention that can quite effectively assess memory for either incidental or target events. These tests so far have indicated a clear ontogenetic decrease in rate of forgetting over short intervals, corresponding to the well-known development-related decrease in forgetting over long intervals (infantile amnesia). The tests also have shown that short-term forgetting of intentional and target events is surprisingly similar, with some indication of more rapid forgetting for the incidental events. Alternative interpretations of the CS? effect and some preliminary tests of these interpretations are discussed. 相似文献
Entirely predictable examinations are ones for which the questions are known in advance. Some assessments are designed this way, but in public examinations, predictability is subtler. Students familiarise themselves with the requirements broadly: likely topics that will come up, question formats and how to maximise their marks. If students can predict what they have to do, they can memorise performances, such as essays, and restrict their learning to fit only with examination requirements. The danger is that this focus could undermine curriculum aims. Further, examinations that are overly predictable might produce results that do not generalise to other performances or have predictive validity. This paper presents part of a broader project investigating whether the Higher Level Irish Leaving Certificate (LC) examinations were too predictable. Here, the development of a rating scale for students’ views of examination predictability is described. Data were collected from 1002 Irish LC students taking higher level examinations in biology (n?=?536), English (n?=?749) and geography (n?=?387). Students’ views on predictability of the examination could be grouped consistently across subject areas into three factors: valuable learning, predictability and narrowing of the curriculum. Belief that narrowing of the curriculum was a good examination preparation tactic had a negative relationship with examination scores and perceived learning value of examinations was positively associated with students’ scores in biology and English. These findings indicate that the scoring system rewards students who believe they must study the discipline broadly. 相似文献
