A framework for synchronous web-based professional development: Measuring the impact of webinar instructionRich, Rachel L. 01 January 2011 (has links)
Through the evolution and proliferation of the Internet, distance and online education have become more prevalent in modern society. Synchronous web-based professional development continues to gain popularity. Although online education has grown in popularity and breadth, there has been a lack of research about the impact of synchronous web-based professional development. By using Kirkpatrick and Kirkpatrick's (2006) Four Levels of Evaluation, this study examined the impact of webinar professional development at a National Science Foundation Advanced Technology Center. Findings indicate that although the factors that contribute to learning in a web-based environment were present, there was a lack of evidence about the actual outcomes of participation in a synchronous web-based professional development. To address the lack of evidence, a new model of Comprehensive Synchronous Web-based Professional Development evaluation and implementation is proposed in the discussion.

A user-centered usability and usefulness evaluation framework of digital libraries in the context of EthiopiaNewayneh, Ketsela Gilats 03 1900 (has links)
Bibliography: leaves 207-224 / Abstracts and keywords following the Appendices / This thesis evaluates Ethiopian higher learning institutes’ digital libraries (DLs) for their usability
and usefulness. The outcome contributes knowledge by helping to propel development efforts;
satisfy DL stakeholders; provide information and fill information gaps; serve as cross-reference
for academicians and researchers in the discipline; make decisions and solve managerial issues in
DLs of the developing world; and provide scientific interests and merits for the advancement of
information systems.
When undertaking usability and usefulness evaluation research in DLs, there is no agreed-upon
established conceptual framework that guides researchers in the developing world. Therefore, the
overall objective of this research is to propose a framework for DL evaluation that fits into the
context of developing countries. As the study is concerned with users’ internal attributes, the
interpretive research paradigm is applied. A qualitative research approach is employed and a case study research design is followed. Multiple data-collection techniques, namely semi-structured
interviews (17 respondents), open-ended questionnaires (17 respondents) and observations (4
observations) are employed. The study encompasses four public university DLs in Ethiopia.
The participants have a positive perception of all attributes of usability. Most of the attributes of
usefulness are also perceived positively, except coverage. The major challenges encountered by
participants are network accessibility, interruption and speed, and access restrictions imposed on
some DL content. DL benefits include easy access to the DL content, enhanced teaching and
research, lower cost and easy sharing of contents. The expectations of users are ensuring resource
availability and sustainability, overcoming the absence of user feedback and federated search
problems, and improving network infrastructure and speed.
The interaction triptych framework (ITF), which is used in the current study, is a well-known
framework that is commonly implemented by researchers. However, since it does not incorporate
the contextual situation of developing countries, ITF has some limitations. Therefore, based on the
output of this empirical research and considering the usability and usefulness themes of ITF and
its relationships with other socio-technical and contextual themes, a contextual DL evaluation
framework is proposed. The proposed framework emphasises the social, institutional and
contextual aspects of DLs. The proposed framework has six DL components, namely: DL user;
content and collection; system and technology; services and support; user interface; and context.
The proposed framework is called a digital library components interaction evaluation framework. / Lo mqondo uhlaziya imitapo yolwazi yedijithali (i-DLs) yezikhungo zokufunda ephezulu zase-Ethiopia
ngokusebenziseka kwazo nokuba wusizo. Umphumela unikela ngolwazi ngokusiza ukuhambisa imizamo
yentuthuko; ukwanelisa ababambiqhaza be-DL; ukuhlinzeka ngolwazi nokugcwalisa izikhala zolwazi;
ukusebenza okubhekiswe kukho kwezifundiswa nabaphenyi emkhakheni; yenza izinqumo futhi ixazulule
izingqinamba zokuphatha kuma-DL wezwe elisathuthuka; futhi unikeze izintshisekelo zesayensi kanye
nokufaneleka ekuthuthukisweni kwezinhlelo zolwazi.
Lapho wenza ucwaningo lokusebenziseka neliwusizo okuhlaziya kuma-DL, akukho luhlaka lomqondo
okuvunyelwene ngalo oluhola abacwaningi ezweni elisathuthuka. Ngakho-ke, inhloso ephelele yalolu
cwaningo ukuphakamisa uhlaka lokuhlaziya kwe-DL oluhambisana nomongo wamazwe asathuthuka.
Njengoba ucwaningo luphathelene nezimpawu zangaphakathi zabasebenzisi, inqubo yocwaningo
ehumushekayo iyasetshenziswa. Indlela yokucwaninga esezingeni elifanele iyasetshenziswa bese
kulandelwa ukwakheka kocwaningo lwesifundo. Kusetshenziswa amasu amaningi wokuqoqa
imininingwane, njengezingxoxo ezihlelwe kahle (abaphenduli abayi-17), imibuzo evulekile (abaphenduli
abayi-17) kanye nokubhekwayo (okubhekwayo oku-4). Lolu cwaningo luhlanganisa ama-DL amane
wemfundo ephakeme yomphakathi wase-Ethiopia.
Abahlanganyeli banombono omuhle wazo zonke izici zokusebenziseka. Iningi lezimpawu eziwusizo
zibonwa kahle futhi, ngaphandle kokumbozwa. Izinselela ezinkulu ababambiqhaza abahlangabezana ngazo
ukufinyeleleka kwenethiwekhi, ukuphazamiseka nejubane, nemikhawulo yokufinyelela ebekiwe kokunye
okuqukethwe kwe-DL. Izinzuzo ze-DL zifaka ukufinyelela okulula kokuqukethwe kwe-DL, ukufundiswa
okuthuthukisiwe nocwaningo, izindleko eziphansi nokwabelana okulula kokuqukethwe. Okulindelwe
abasebenzisi ukuqinisekisa ukutholakala kwezinsiza nokusimama, ukunqoba ukungabi bikho
kwempendulo yomsebenzisi nezinkinga zokusesha ezihlanganisiwe, nokwenza ngcono ingqalasizinda
yenethiwekhi nejubane.
Uhlaka lokusebenzisana lwe-triptych (ITF), olusetshenziswa ocwaningweni lwamanje, uhlaka olwaziwa
kakhulu olusetshenziswa ngokuvamile ngabaphenyi. Kodwa-ke, njengoba lungafaki isimo somongo
samazwe asathuthuka, i-ITF inemikhawulo ethile. Ngakho-ke, ngokuya ngokukhishwa kwalolu cwaningo
olunamandla kanye nokubheka ukusebenziseka nosizo lwezindikimba ze-ITF kanye nobudlelwano bayo
nezinye izingqikithi zomphakathi nezobuchwepheshe nezingqikithi zomongo, kuhlongozwa uhlaka lokuhlaziya lomongo lwe-DL. Uhlaka oluhlongozwayo lugcizelela izici zenhlalo, zesikhungo nezingqikithi
zomongo zama-DL. Uhlaka oluhlongozwayo lunezingxenye eziyisithupha ze-DL, okuyilezi: Umsebenzisi
we-DL; okuqukethwe neqoqo; uhlelo nobuchwepheshe; izinsizakalo nokwesekwa; isikhombimsebenzisi
somsebenzisi nomongo. Uhlaka oluhlongozwayo lubizwa ngohlaka lokuhlaziya kokusebenzisana
kokuqukethwe komtapo wolwazi wedijithali. / Hierdie proefskrif evalueer Ethiopië se hoër leerinstellings se digitale biblioteke (DBe) ten opsigte
van hulle bruikbaarheid en nuttigheid. Die uitkoms dra by tot kennis wat kan help om die
ontwikkelingspogings aan te dryf; om belanghebbers van digitale biblioteke tevrede te hou; om
inligting te verskaf en inligtingsgapings te vul; deur te dien as kruisverwysing vir akademici en
navorsers in die vakgebied; om besluite te neem en bestuursaangeleenthede in digitale biblioteke
van die ontwikkelende wêreld op te los; en om wetenskaplike belange en meriete vir die
bevordering van inligtingstelsels te voorsien.
Wanneer bruikbaarheids- en nuttigheidsevalueringsnavorsing in digitale biblioteke onderneem
word, is daar geen ooreengekome, gevestigde raamwerk wat leiding aan navorsers in die
ontwikkelende wêreld kan gee nie. Die algehele doelwit van hierdie navorsing was derhalwe om
’n raamwerk vir die evaluaering van digitale biblioteke voor te stel wat in die konteks van
ontwikkelende lande pas. Omdat die studie gemoeid is met gebruikers se interne eienskappe, is die
vertolkende paradigma gebruik. ’n Kwalitatiewe navorsingsbenadering is gebruik en ’n
gevallestudie-navorsingsontwerp is gevolg. Veelvuldige data-insamelingstegnieke, naamlik
semigestruktureerde onderhoude (17 respondente), oop vraelyste (17 respondente) en
waarnemings (vier waarnemigs), is ingespan. Die studie sluit vier openbare universiteite se digitale
biblioteke in Ethiopië in.
Die deelnemers het ’n positiewe persepsie van al die eienskappe van bruikbaarheid. Die meeste
van die eienskappe van nuttigheid word ook as positief waargeneem, met die uitsluiting van
voorsiening. Die grootste uitdagings wat die deelnemers ervaar het, was
netwerktoeganklikheid, -onderbrekings en -spoed en die toegangbeperkings wat sommige digitale
biblioteke oplê. Voordele van digitale biblioteke sluit die volgende in: toegang tot
digitalebiblioteekinhoud; beter onderrig en navorsing; laer koste; en die maklike deel van inhoud
met ander. Die verwagtings van gebruikers verseker hulpbronbeskikbaarheid en -volhoubaarheid,
en om die afwesigheid van gebruikersterugvoer en gefedereerde soekprobleme en die verbetering
van netwerkinfrastruktuur en -spoed te oorkom.
Die interaksietriptiekraamwerk (ITF) wat in hierdie studie gebruik is, is ’n bekende raamwerk wat
algemeen deur navorsers geïmplementeer word. Omdat dit egter nie die kontekstuele situasie van
ontwikkelende lande inkorporeer nie, het ITF sekere beperkings. Gebaseer op die uitset van hierdie
empiriese navorsing en met die inagneming van die bruikbaarheids- en nuttigheidstemas van ITF
en sy verhouding met ander sosio-tegniese en kontekstuele temas, word ’n kontekstuele
digitalebiblioteekraamwerk derhalwe voorgestel. Die voorgestelde raamwerk beklemtoon die
sosiale, institusionele en kontekstuele aspekte van digitale biblioteke. Die voorgestelde raamwerk
het ses digitalebiblioteekkomponente, naamlik: digitalebiblioteekgebruiker; inhoud en insameling;
stelsel en tegnologie; dienste en ondersteuning; gebruikerkoppelvlak; en konteks. Die voorgestelde
raamwerk word ’n interaksie-evalueringsraamwerk vir digitalebiblioteekkomponente genoem. / School of Computing / D. Phil. (Information Systems)

A methodology for evaluating intelligent tutoring systemsPadayachee, Indira 06 1900 (has links)
Dissertation / This dissertation proposes a generic methodology for evaluating intelligent tutoring systems (ITSs),
and applies it to the evaluation of the SQL-Tutor, an ITS for the database language SQL.
An examination of the historical development, theory and architecture of intelligent tutoring
systems, as well as the theory, architecture and behaviour of the SQL-Tutor sets the context for this
study. The characteristics and criteria for evaluating computer-aided instruction (CAl) systems are
considered as a background to an in-depth investigation of the characteristics and criteria
appropriate for evaluating ITSs. These criteria are categorised along internal and external
dimensions with the internal dimension focusing on the intrinsic features and behavioural aspects
of ITSs, and the external dimension focusing on its educational impact. Several issues surrounding
the evaluation of ITSs namely, approaches, methods, techniques and principles are examined, and
integrated within a framework for assessing the added value of ITS technology for instructional
purposes. / Educational Studies / M. Sc. (Information Systems)

An evaluation framework for virtual reality safety training systems in the South African Mining IndustryVan Wyk, Etienne Anton 02 1900 (has links)
The mining industry in South Africa contributes significantly to the national economy. Despite stringent safety legislation, mining accidents cause numerous fatalities and injuries. Inadequate or insufficient training is often cited as a root cause of accidents. Conventional class-based safety training has not reduced the incidence of accidents significantly. By contrast, virtual reality training tools can provide simulated exposure to real-world working conditions without the associated risks.
This study describes the application of design-based research (DBR) in the design and development of two desktop virtual reality (VR) systems for safety training in the South African mining industry. The results of a usability context analysis were applied in the design of a VR prototype on generic hazards recognition and rectification, which was used and evaluated at South Africa‘s largest platinum mine site. A case study was conducted to investigate the causes and occurrences of falls of ground, which resulted in the design and development of a second VR prototype focusing on identifying and addressing underground geological conditions.
DBR was also used in the generation of an evaluation framework for evaluating VR training systems, namely the Desktop VR Evaluation Framework (DEVREF), which is the major deliverable of the research. DEVREF can make a major contribution to the domain of e-training in mines and is transferable and customisable beyond its initial application. The process flow of the research thus moved beyond merely providing a solution to a complex real-world problem and became a classic DBR study with dual outcomes, namely a practical real-world solution in the form of two VR training systems and a theoretical contribution in the form of the DEVREF evaluation framework. DEVREF evaluates the design of desktop VR training systems in the categories of instructional design, usability, VR systems design, and context-specific criteria for mining. The use of DEVREF is demonstrated by reporting the application of its criteria in evaluating the two VR training systems. Heuristic evaluation, end-user surveys, and interviews were used as evaluation methods.
A third contribution is methodological, in that this work proposes a new DBR process model and an interaction design lifecycle model suitable for VR training systems. / Computing / D. Phil. (Information Systems)
