Conversing with pedagogical agents: A phenomenological exploration of interacting with digital entities

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.     

Responding to student expectations: a partnership approach to course evaluation

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.     

Heterogeneity in the Effects of College Course Placement

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.

     

Facing and bridging gaps in Web searching

Drawing on the ideas of the Sense-Making approach, the ways in which people face and bridge gaps in Web searching are analyzed. The empirical study is based on videotaped Web searches conducted by seven participants. Altogether 11 gaps and 13 search tactics of various types were identified. The gaps faced by the searchers originated from three major factors: problematic content of information, insufficient search competence and problems caused by the search environment. Of individual gaps, no relevant material available, inaccessible content and confusion were most frequent. Of the search tactics used in gap-bridging, following links and activating the Back button were most popular. Gaps related to the problematic content of information led the informants to redirect the search to find Web pages that focus better on the search topic. If the movement was stopped by insufficient search competence, the searchers tended to return to material that was familiar from earlier use contexts in order to regain control of the search process. Alternatively, they tried to specify the search terms. In cases where the search was interrupted by technical problems or other factors originating from the search system, gap-bridging aimed at returning to familiar and technically reliable links. The Sense-Making theory provides relevant conceptual tools to approach the dynamic and discontinuous nature of Web searching in terms of gap-facing and gap-bridging. The concept of gap-facing enables a context-sensitive analysis of the ways in which Web search processes may be stopped. Gap-bridging indicates a general level motive to find alternative ways to continue searching.     

Ugandan adolescents’ sources,interpretation and evaluation of sexual content in entertainment media programming

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.     

The veridicality of punitive childhood experiences reported by adolescents and young adults

OBJECTIVE: The primary goal of the present research was to determine whether retrospective reports of childhood disciplinary experiences and perceptions of that discipline correspond to actual childhood events and whether the accuracy of that report was influenced by the affective state of the respondent. METHOD: Eighty-three adolescent and young adult males completed a retrospective measure of physical child maltreatment, Assessing Environments (AEIII), and the Brief Symptom Inventory (BSI). As children the participants had been observed naturalistically in their homes interacting with their parents an average of 10 years earlier. RESULTS: Analyses were consistent with the hypothesis that both current mood and actual observations of parent-child interactions during childhood predict self-reported recollections of childhood maltreatment by one's parents. Further the veridicality of such recollections appears to depend upon the objective specificity versus the perceptive nature of the questions used to elicit the recollections. CONCLUSIONS: The findings suggest that assessment instruments suitable for obtaining information regarding earlier childhood victimization must utilize behaviorally specific items. Thus, items that are either global or intimate a normative comparison should be avoided.     

A VBA‐based Simulation for Teaching Simple Linear Regression

In spite of the name, simple linear regression presents a number of conceptual difficulties, particularly for introductory students. This article describes a simulation tool that provides a hands‐on method for illuminating the relationship between parameters and sample statistics.
