Using effective information searching skills to solve problems

Lakshmanan, Muthukumar S January 2009 (has links)
"2008". / Thesis (PhD)--Macquarie University, Australian Centre for Educational Studies, School of Education, 2009. / Bibliography: p. 268-283. / Introduction -- Review of the literature -- Methods and procedures -- Pre-intervention qualitative data analysis & discussion of findings -- Intervention -- Post-intervention qualitative data analysis & discussions of findings -- Post-intervention quantitative data analysis & discussions of findings -- Conclusions. / Problem-based learning (PBL) is an instructional approach that is organized around the investigation and resolution of problems. Problems are neither uniform nor similar. Jonassen (1998, 2000) in his design theory of problem solving has categorized problems into two broad types - well-structured and ill-structured. He has also described a host of mediating skills that impact problem solving outcomes. However, this list of skills is not exhaustive and in view of the utility of the Internet as an informational repository, this study examined the need for effective information searching skills to be included in this list. -- This study was aimed at studying how students solve well and ill structured problems and how different Internet information seeking strategies can be used to engage in problem solving. This study devised and empirically tested the efficacy of an interventionist conceptual model that maps the application of different information seeking techniques to successfully resolving well and ill structured problem types. The intervention helps to better understand the influence of information searching skills on problem solving performance and the various problem solving strategies students can adopt in approaching problem solving. The contrasting patterns of navigational path movements taken by students in seeking information to resolve ill and well structured problems were also investigated. -- A mixed methodology research design, involving a mix of quantitative and qualitative approaches was used in this study. The research site was a polytechnic in Singapore that has implemented problem-based learning in its curriculum design. A first year class of 25 students were the sample population who participated in this study. Six problems from the curriculum were chosen for this study - three well-structured and another three ill-structured problems. -- The research findings of this study inform that information searching skills indeed play an important role in problem solving. The findings affirm the need for students to be systematically instructed in the skills of information searching to be aware of the complexities involved in information seeking and accomplish desired problem solving goals. This study has also shown that well and ill structured problems demand different cognitive and information seeking capabilities. Well-structured problems are easily solved and come with singular correct answers. The information searching necessary for solving well-structured problems is constrained and readily manageable. Thus, students only have to be acquainted with fundamental information searching skills to solve well-structured problems. On the other hand, ill-structured problems are messy and contain a number of unknown elements. There are no easy prototypic solutions. Subsequently, the information needs of ill-structured problems are usually complex, multi-disciplinary and expansive. Hence, students have to be trained to apply a more advanced set of information searching skills in resolving ill-structured problems. / Mode of access: World Wide Web. / xiv, 283 p. ill

A study of the information-seeking behaviour of the researchers in the Parliamentary Research Unit at the Parliament of the Republic of South Africa

Swartz, Barbara Dawn 03 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2005. / ENGLISH ABSTRACT: This study examined the information seeking behaviour of the researchers attached to the Parliamentary Research Unit in Parliament. It looked at their use of the Parliamentary Library, their use of the library and its resources, what other avenues for information they use and what suggestions they have for improving the service. A questionnaire was developed and e-rnailed to researchers. As the response rate was poor, it limited the conclusions that could be drawn from the research. In line with other studies, it was found that electronic resources and the Internet played a great role in how they sourced information. Researchers frequented the Internet to find information more than they use the library and they have difficulties with accessing online resources and the catalogue. The manual circulation system was a source of frustration as well. They made use of personal contacts to a certain extent to find unpublished information and very recent information. These categories of information, especially government information, are crucial to their work. Suggestions for improvement centred on the online catalogue, instruction in the use of the online resources, updating the collection of books and journals and consulting researchers where necessary. / AFRIKAANSE OPSOMMING: Hierdie ondersoek fokus op die inligtingsgedrag van die navorsers in die Parlementêre Navorsingseenheid. Dit ondersoek hul gebruik van die Parlementêre biblioteek en sy bronne, die alternatiewe inligtingskanale tot hul beskikking en watter voorstelle hulle het vir die verbetering van dienste. 'n Vraelys is ontwerp en per e-pos aan navorsers gestuur. Swak terugvoering het die proses om finale gevolgtrekkings te maak, beperk. In ooreenstemming met ander studies, is wel gevind dat die Internet en elektroniese bronne 'n groot rol speel in die proses om inligting te bekom. Daar is ook gevind dat navorsers hierdie tipe bronne verkies bo traditionele biblioteekbesoeke. Opleiding om die elektroniese bronne en die katalogus te gebruik is noodsaaklik. Alternatiewe bronne van inligting soos persoonlike kontakte met ander kundiges word tot 'n sekere mate gebruik om inligting te kry wat beide op datum en ongepubliseer is. Voorstelle vir verbetering fokus op die elektroniese katalogus, opleiding in die gebruik van elektroniese bronne, die kwaliteit en inhoud van die versameling en konsultasie met die navorsers.

A comparison of web-based technologies to serve images from an Oracle9i database

Swales, Dylan 18 June 2013 (has links)
The nature of Internet and Intranet Web applications has changed from a static content-distribution medium into an interactive, dynamic medium, often used to serve multimedia from back-end object-relational databases to Web-enabled clients. Consequently, developers need to make an informed technological choice for developing software that supports a Web-based application for distributing multimedia over networks. This decision is based on several factors. Among the factors are ease of programming, richness of features, scalability, and performance. The research focuses on these key factors when distributing images from an Oracle9i database using Java Servlets, JSP, ASP, and ASP.NET as the server-side development technologies. Prototype applications are developed and tested within each technology: one for single image serving and the other for multiple image serving. A matrix of recommendations is provided to distinguish which technology, or combination of technologies, provides the best performance and development platform for image serving within the studied envirorunent. / KMBT_363 / Adobe Acrobat 9.54 Paper Capture Plug-in

An Empirical Study of How Novice Programmers Use the Web

Tula, Naveen 05 1900 (has links)
Students often use the web as a source of help for problems that they encounter on programming assignments.In this work, we seek to understand how students use the web to search for help on their assignments.We used a mixed methods approach with 344 students who complete a survey and 41 students who participate in a focus group meetings and helped in recording data about their search habits.The survey reveals data about student reported search habits while the focus group uses a web browser plug-in to record actual search patterns.We examine the results collectively and as broken down by class year.Survey results show that at least 2/3 of the students from each class year rely on search engines to locate resources for help with their programming bugs in at least half of their assignments;search habits vary by class year;and the value of different types of resources such as tutorials and forums varies by class year.Focus group results exposes the high frequency web sites used by the students in solving their programming assignments.

An investigation into the use of the Internet by students at St. Joseph's Theological Institute, KwaZulu-Natal, South Africa.

Shezi, Mhlukanisi Simon. January 2006 (has links)
The discussion of introducing the Internet at St. Joseph's Theological Institute in KwaZulu-Natal, South Africa took place in 2002 and access to the Internet was introduced in 2003 via 70 computers which were housed in the library. Given that the Internet has emerged as an important learning tool at the tertiary level, the aim of the study was to investigate the use of the Internet by the students at St. Joseph's. The specific objectives of the study were as follows: to find out which students were using the Internet, to find out what students were using the Internet for, to find how often students used the Internet and when they used it, to find out the problems experienced by those students who used the Internet, to find out why certain students do not use the Internet, and lastly the study aimed to make recommendations concerning the use of the Internet by students. The survey research method was used and the data was collected through a self administered questionnaire. No sampling was done as the entire population of 188 students was surveyed. Sixty five students responded - a response rate of 34.6 %. Findings revealed that of the 65 students who completed the questionnaires 34 (52.3%) had used the Internet and 31 (47.6%) had not. Out of the 24 respondents who gave reasons for not having used the Internet, the majority 17 (70.8%) of respondents said that they had not received formal training and did not know how to use the Internet. The major problems facing the Internet users at St. Joseph 's were the shortage of computers mentioned by 13 (38.2%) respondents and computers being slow as indicated by 13 (38.2%) respondents. Six (17.6%) respondents also pointed to not having enough training in the use of Internet facilities. Recommendations concerning Internet use at the Institute were made and suggestions for further research put forward. / Thesis (M.I.S.)-University of KwaZulu-Natal, Pietermaritzburg, 2006.

Internet use among university students in Kenya : a case study of the University of Nairobi

Waithaka, Mercy Wangechi 09 1900 (has links)
The researcher investigated internet usage among students at the University of Nairobi using a quantitative case study method. A questionnaire-based survey was done among 381 students and face-to-face interviews were conducted with the university‟s library staff. The research findings indicate that the students' level of awareness about the internet services offered at the university was high. The students had good basic computer and internet skills; however, they lacked more advanced skills and this negatively affected their use of internet resources. The students used the internet for various purposes, including to study, teach and do research; to communicate; and for social interaction. The major recommendations of the study include providing formal internet training and adequate facilities; implementing a better, inclusive policy on internet use; and better co-ordinated university efforts. Free internet access should be made available to all the university students, if not all members of the university community. / Information Science / M.A. (Information Science)

Cross-Cultural Comparative Study of Users’ Perception of the Navigation Organization of an E-Commerce Web Application

Bilyayeva, Tetiana A 01 January 2012 (has links)
The object of this study was to assess the influence of native language, as a principal cultural characteristic, one users’ behavior when using a web-based e-commerce application. The study expands on previous research by comparing English and Russian users. The research also considered demographic data to assess additional factors that influence behavior and task performance. The research design encompassed an online shopping application with two different navigation menus. One menu was based on the action-object model and the other was based on the object-action model. The user interface was created in two different languages (Russian and English). This study suggests that language, as a cultural indicator, has a direct relationship to user satisfaction and performance in e-commerce web applications.
