The virtual classroom: building the foundations

This is a report on the first year of a three-year project concerned with the development and assessment of new types of software capabilities designed to support university level courses. A virtual classroom or university without walls is being created within a computerized conferencing system. During the first year of the project, students in twelve courses at three universities completed part or all of their coursework online. Pre and post-course questionnaires and automatic monitoring of their computer-mediated communications are the main sources of data. Independent variables include the expectations and attributes of the individual students; characteristics of the particular hardware and software which they use; and variations among classes in the nature of the assignments and activities required or facilitated by the instructor. Intervening variables include the amount and type of use of the system by the students, and the extent to which group learning takes place. Dependent variables are course outcomes and judgments by the students about the relative value of traditional and virtual classrooms. There is considerable variance in outcomes, particularly in student assessments of whether the virtual classroom is a better learning experience and whether they learned more or learned less. There was also extreme variation in measures of activity levels by students. For instance, the mean number of student sessions online was 41, but the standard deviation was 61; and the mean number of comments (contributions per student to the class discussion) was six, while the standard deviation was eight. Variations in measures of online activity and outcomes were significantly related to course, pre-use expectations of the students, sex, and system access variables including workstation hardware and response time. However, the strongest relationships are for measures of process vs. outcome. Those students who actively participated (by making comments rather than just reading the comments of others, and by engaging in private communication online with a number of other students as well as the professor) and those students who experienced group learning (learning from peer-group activity rather than one-way transmission of knowledge from professor to student) reported the most positive outcomes

Online discussion in engineering education : student responses and learning outcomes

A ubiquitous and widely used feature of online learning environments is the asynchronous discussion board. This chapter presents a case study of the introduction and evaluation of student use of an online discussion in an engineering management study unit. We introduced an assessable assignment task based on student use of an online discussion, in response to falling student unit evaluation results after we initially moved the unit to wholly online delivery mode. Both quantitative and qualitative unit evaluation data suggest that students perceive value in the online discussion activities. A regression analysis based on discussion usage data suggests that students derived significant learning outcome benefit toward their final unit grade from making reflective postings in the online discussion.<br /

TLAD 2010 Proceedings:8th international workshop on teaching, learning and assesment of databases (TLAD)

This is the eighth in the series of highly successful international workshops on the Teaching, Learning and Assessment of Databases (TLAD 2010), which once again is held as a workshop of BNCOD 2010 - the 27th International Information Systems Conference. TLAD 2010 is held on the 28th June at the beautiful Dudhope Castle at the Abertay University, just before BNCOD, and hopes to be just as successful as its predecessors.The teaching of databases is central to all Computing Science, Software Engineering, Information Systems and Information Technology courses, and this year, the workshop aims to continue the tradition of bringing together both database teachers and researchers, in order to share good learning, teaching and assessment practice and experience, and further the growing community amongst database academics. As well as attracting academics from the UK community, the workshop has also been successful in attracting academics from the wider international community, through serving on the programme committee, and attending and presenting papers.This year, the workshop includes an invited talk given by Richard Cooper (of the University of Glasgow) who will present a discussion and some results from the Database Disciplinary Commons which was held in the UK over the academic year. Due to the healthy number of high quality submissions this year, the workshop will also present seven peer reviewed papers, and six refereed poster papers. Of the seven presented papers, three will be presented as full papers and four as short papers. These papers and posters cover a number of themes, including: approaches to teaching databases, e.g. group centered and problem based learning; use of novel case studies, e.g. forensics and XML data; techniques and approaches for improving teaching and student learning processes; assessment techniques, e.g. peer review; methods for improving students abilities to develop database queries and develop E-R diagrams; and e-learning platforms for supporting teaching and learning

Does the discussion help? The impact of a formally assessed online discussion on final student results

While there is agreement that participation in online asynchronous discussions can enhance student learning, it has also been identified that there is a need to investigate the impact of participation in online discussions on student course performance. This paper presents a case study based on an undergraduate engineering management unit employing a formally assessed online discussion area. It was observed that while many students read a significant number of discussion postings, generally, the posting of new and reply messages occurred at the minimum level required to qualify for the assignment marks. Based on correlation and multiple regression analysis, it was observed that two variables were significantly related to a student\u27s final unit mark&mdash;prior academic ability and the number of new postings made to the online discussion. Each new posting contributed three times as much to the final unit mark as its nominal assessment value, suggesting that the work in preparing their new discussion postings assisted students in the completion of a range of assessable tasks for the unit. The number of postings read was not significantly correlated with the final unit mark, suggesting that passive lurking in this online discussion did not significantly contribute to student learning outcomes.<br /

Attention or Appreciation? The Impact of Feedback on Online Volunteering

We examine how different types of feedback influence online volunteer contributions in the context of online consultations for college entrance applications, which requires the volunteer counselor and the person receiving help (the counselee) to be online at the same time. We investigate the impact of two types of feedback on volunteers’ participation: 1) appreciation, as reflected in the number of positive ratings received by a counselor from counselees; and 2) attention, as reflected in the readership of a counselor’s profile page. We find that appreciation encourages the volunteer to engage in more helping behavior, likely because it can activate the volunteer’s altruistic motivation. In contrast, attention discourages volunteers to offer more help, possibly because they feel they have accomplished enough or because they feel passed over when they receive a lot of attention but few requests for consultations. The findings suggest that platform designers should encourage appreciation from those helped and provide more nuanced feedback about attention

Translating the Concept of Goal Setting into Practice -- What 'Else' does it Require than a Goal Setting Tool?

This conceptual paper reviews the current status of goal setting in the area of technology enhanced learning and education. Besides a brief literature review, three current projects on goal setting are discussed. The paper shows that the main barriers for goal setting applications in education are not related to the technology, the available data or analytical methods, but rather the human factor. The most important bottlenecks are the lack of students goal setting skills and abilities, and the current curriculum design, which, especially in the observed higher education institutions, provides little support for goal setting interventions.Comment: This paper has been accepted to be published in the proceedings of CSEDU 2020 by SciTePres

The Nature of Optional Sibilant Harmony in Navajo

This thesis represents investigates optional sibilant harmony in Navajo using the first person possessive morpheme, which contains an underlyingly palatal sibilant that may harmonize to alveolar when affixed to noun stems that contain [+anterior] sibilants. The literature commonly describes sibilant harmony as being mandatory in Navajo when sibilants are in adjacent syllables, and optional when there is more distance between sibilants. In other words, sibilant disharmony is ungrammatical, but gradiently rather than categorically; in some instances disharmony is ungrammatical enough that it must be repaired through assimilation, while in other instances it is less ungrammatical and may be tolerated. The statistical nature of the variation in these optional harmony settings is not fully understood, however, and the three studies contained within this thesis were designed to investigate how often assimilation occurs in nonmandatory environments and to identify factors that contribute to the variability observed. In the first study, a Google search was used to evaluate sibilant harmony in online Navajo language use in the Spring of 2008 and again in the Spring of 2010. The findings present a picture of optional sibilant harmony that differs somewhat from the traditional view; harmony seems to be optional even in the environment that has traditionally been described as mandatory, and it occurs far less frequently than anticipated. These results led to the creation of an online survey wherein fluent speakers of Navajo provided grammaticality judgments of both assimilated and unassimilated forms. Almost universally, respondents preferred the unassimilated shi- even in those environments where assimilation would previously have been considered mandatory. The third study involved the recording of data from three speakers of Navajo, none of whom use the assimilated si- either in writing or in speech--at least, not to a degree that is discernible to the naked ear. Acoustic analysis was performed to determine whether the prefix-initial palatal sibilant is acoustically consistent across the board--duration, spectral mean, onset of frication energy, and the second formant of the following vowel were measured to investigate whether the prefixal esh differs acoustically when it appears before words that contain potential triggers than when it does not. Analysis reveals some differences in the spectral mean and duration of the fricative portion of the first person possessive morpheme when it occurs before stems that contain [+anterior] sibilants. Taken together, the findings presented herein suggest that the mandatory sibilant harmony environment no longer exists in Navajo, at least with regards to the first person possessive morpheme. Harmony is far less prevalent than expected overall, and is wholly absent for some speakers. The factors of continuancy and adjacency were found to contribute significantly to the gradience observed in all three studies, however, even for those speakers who do not overtly use assimilation
