Multitasking web searching and implications for design

Bu çalışma, Kaliforniya[ABD]'de 19-22 Ekim tarihleri arasında düzenlenen 66. Annual Meeting of the American-Society-for-Information-Science-and-Technology'de bildiri olarak sunulmuştur.This paper presents findings from a study of users multitasking searches on Web search engines. A user's single session with a Web search engine may consist of seeking information on single or multiple topics. Limited research has focused on multitasking search and the implications for Web design. Incidence of multitasking search by AlltheWeb.com and Excite Web search engine users were filtered from transaction logs. Findings include: (1) multitasking Web searches are a noticeable user behavior, one tenth of Excite users and one third of AlltheWeb.com users conducted multitasking searches, (2) multitasking search sessions are longer than regular search sessions in terms of queries per session and duration, (3) both Excite and AlltheWeb.corn users search for about three topics per multitasking session and submit about 4-5 queries per topic, and (4) there is a broad variety of search topics in multitasking search sessions. The implications of our findings for Web design and further research are discussed.American Society for Information Science & Technolog

Cross Validation Of Neural Network Applications For Automatic New Topic Identification

There are recent studies in the literature on automatic topic-shift identification in Web search engine user sessions; however most of this work applied their topic-shift identification algorithms on data logs from a single search engine. The purpose of this study is to provide the cross-validation of an artificial neural network application to automatically identify topic changes in a web search engine user session by using data logs of different search engines for training and testing the neural network. Sample data logs from the Norwegian search engine FAST (currently owned by Overture) and Excite are used in this study. Findings of this study suggest that it could be possible to identify topic shifts and continuations successfully on a particular search engine user session using neural networks that are trained on a different search engine data log

'First Portal in a Storm': A Virtual Space for Transition Students

The lives of millennial students are epitomised by ubiquitous information, merged technologies, blurred social-study-work boundaries, multitasking and hyperlinked online interactions (Oblinger & Oblinger, 2005). These characteristics have implications for the design of online spaces that aim to provide virtual access to course materials, administrative processes and support information, all of which is required by students to steer a course through the storm of their transition university experience. Previously we summarised the challenges facing first year students (Kift & Nelson, 2005) and investigated their current online engagement patterns, which revealed three issues for consideration when designing virtual spaces (Nelson, Kift & Harper, 2005). In this paper we continue our examination of students’ interactions with online spaces by considering the perceptions and use of technology by millennial students as well as projections for managing the virtual learning environments of the future. The findings from this analysis are informed by our previous work to conceptualise and describe the architecture of a transition portal

The new shape of the student

This chapter critically examines student characteristics in light of the popular dis-course which describes students as part of a net generation of digital native young people. Digital and networked technologies have clearly changed the possibilities for students to learn and the ways in which teaching and learning can be conducted. It is also claimed that new technologies change what students are able to learn. However the claim that there is a new generation of learners characterized by a new mentality has to be careful assessed in the light of recent empirical evidence. The idea of a generation gap between digitally native students and their digitally immigrant teachers is challenged, as are claims that pressure from this new generation forces radical institutional change on educational institutions. The chapter argues against the generational nature of the argument and separates the technological changes that are taking place from the determinist rhetoric they have been couched in. This rhetoric suggests that changes amongst students are already well understood and that their educational implications are already known and lead to generally applicable if not universal consequences. The chapter concludes by arguing that there is no one shape for students and that digital technologies open up a range of opportunities and choices at all levels of education

Personality, Technology, and Learning

Computers continued encroachment on today’s society can be seen in a college lecture hall, where a growing number of students use laptops for their academic needs. Current academic laptop use research predominantly makes broad generalizations across users, indicating that laptop use in the classroom has negative influences on academic outcomes. However, this research neglects to take into account possible individual differences in the users. It is hypothesized that students\u27 levels of conscientiousness and impulsivity would moderate the relationship between laptop use and academic performance, while a student’s multitasking experience would mediate this same relationship, forming a moderated mediation model. Using an online sample of college aged students (N= 195), the hypothesized moderated mediation model was not supported. Students\u27 levels of conscientiousness or impulsivity do not moderate the relationship between laptop use and academic performance, and a student’s multitasking experience does not mediate this same relationship

The net generation and digital natives: implications for higher education

Executive Summary "Our students have changed radically. Today�s students are no longer the people our educational system was designed to teach." (Prensky 2001 p1) 1. There is no evidence that there is a single new generation of young students entering Higher Education and the terms Net Generation and Digital Native do not capture the processes of change that are taking place. 2. The complex changes that are taking place in the student body have an age related component that is most obvious with the newest waves of technology. Prominent amongst these are the uses made of social networking sites (e.g. Facebook), uploading and manipulation of multimedia (e.g. YouTube) and the use of handheld devices to access the mobile Internet. 3. Demographic factors interact with age to pattern students� responses to new technologies. The most important of these are gender, mode of study (distance or place-based) and the international or home status of the student. 4. The gap between students and their teachers is not fixed, nor is the gulf so large that it cannot be bridged. In many ways the relationship is determined by the requirements teachers place upon their students to make use of new technologies and the way teachers integrate new technologies in their courses. There is little evidence that students enter university with demands for new technologies that teachers and universities cannot meet. 5. Students persistently report that they prefer moderate use of Information and Communication Technologies (ICT) in their courses. Care should be taken with this finding because the interpretation of what is �moderate� use of ICT may be changing as a range of new technologies take off and become embedded in social life and universities. 6. Universities should be confident in the provision of what might seem to be basic services. Students appreciate and make use of the foundational infrastructure for learning, even where this is often criticised as being an out of date and unimaginative use of new technology. Virtual Learning Environments (Learning or Course Management Systems) are used widely and seem to be well regarded. The provision by university libraries of online services, including the provision of online e-journals and e-books, are also positively received. 7. Students do not naturally make extensive use of many of the most discussed new technologies such as Blogs, Wikis and 3D Virtual Worlds. The use of 3D Virtual Worlds is notably low amongst students. The use of Wikis and Blogs is relatively low overall, but use does vary between different contexts, including national and regional contexts. Students who are required to use these technologies in their courses are unlikely to reject them and low use does not imply that they are inappropriate for educational use. The key point being made is that there is not a natural demand amongst students that teaching staff and universities should feel obliged to satisfy. 8. There is no obvious or consistent demand from students for changes to pedagogy at university (e.g. demands for team and group working). There may be good reasons why teachers and universities wish to revise their approaches to teaching and learning, or may wish to introduce new ways of working. Students will respond positively to changes in teaching and learning strategies that are well conceived, well explained and properly embedded in courses and degree programmes. However there is no evidence of a pent-up demand amongst students for changes in pedagogy or of a demand for greater collaboration. 9. There is no evidence of a consistent demand from students for the provision of highly individualised or personal university services. The development of university infrastructures, such as new kinds of learning environments (for example Personal Learning Environments) should be choices about the kinds of provision that the university wishes to make and not a response to general statements about what a new generation of students are demanding. 10. Advice derived from generational arguments should not be used by government and government agencies to promote changes in university structure designed to accommodate a Net Generation of Digital Natives. The evidence indicates that young students do not form a generational cohort and they do not express consistent or generationally organised demands. A key finding of this review is that political choices should be made explicit and not disguised by arguments about generational change

A new integrated model for multitasking during web searching

Investigating multitasking information behaviour, particularly while using the web, has become an increasingly important research area. People s reliance on the web to seek and find information has encouraged a number of researchers to investigate the characteristics of information seeking behaviour and the web seeking strategies used. The current research set out to explore multitasking information behaviour while using the web in relation to people s personal characteristics, working memory, and flow (a state where people feel in control and immersed in the task). Also investigated were the effects of pre-determined knowledge about search tasks and the artefact characteristics. In addition, the study also investigated cognitive states (interactions between the user and the system) and cognitive coordination shifts (the way people change their actions to search effectively) while multitasking on the web. The research was exploratory using a mixed method approach. Thirty University students participated; 10 psychologists, 10 accountants and 10 mechanical engineers. The data collection tools used were: pre and post questionnaires, pre-interviews, a working memory test, a flow state scale test, audio-visual data, web search logs, think aloud data, observation, and the critical decision method. Based on the working memory test, the participants were divided into two groups, those with high scores and those with lower scores. Similarly, participants were divided into two groups based on their flow state scale tests. All participants searched information on the web for four topics: two for which they had prior knowledge and two more without prior knowledge. The results revealed that working memory capacity affects multitasking information behaviour during web searching. For example, the participants in the high working memory group and high flow group had a significantly greater number of cognitive coordination and state shifts than the low working memory group and low flow group. Further, the perception of task complexity was related to working memory capacity; those with low memory capacity thought task complexity increased towards the end of tasks for which they had no prior knowledge compared to tasks for which they had prior knowledge. The results also showed that all participants, regardless of their working memory capacity and flow level, had the same the first frequent cognitive coordination and cognitive state sequences: from strategy to topic. In respect of disciplinary differences, accountants rated task complexity at the end of the web seeking procedure to be statistically less significant for information tasks with prior knowledge compared to the participants from the other disciplines. Moreover, multitasking information behaviour characteristics such as the number of queries, web search sessions and opened tabs/windows during searches has been affected by the disciplines. The findings of the research enabled an exploratory integrated model to be created, which illustrates the nature of multitasking information behaviour when using the web. One other contribution of this research was to develop new more specific and closely grounded definitions of task complexity and artefact characteristics). This new research may influence the creation of more effective web search systems by placing more emphasis on our understanding of the complex cognitive mechanisms of multitasking information behaviour when using the web

Flow in multitasking : the effects of motivation, artifact, and task factors

textThe aims of this dissertation study are 1) to examine how the interplay of motivation, artifacts, and task interconnectedness affect users' flow experience, 2) to understand users' multitasking patterns by analyzing approaches and strategies in multitasking environments through a participatory design session, and 3) to come up with design insights and implications for desired multitasking environments based on findings from the quantitative and qualitative data analysis and synthesis. This dissertation employed the PAT (Person-Artifact-Task) model to examine factors that affect users' flow experience in computer-mediated multitasking environments. Particularly, this study focused on users' flow experience - sense of control, focused attention, curiosity, intrinsic interest and interactivity - in the context of multitasking. The dissertation begins with perspectives on human multitasking research from various disciplines. Emphasis is placed on how researchers have defined the term multitasking and the scope of previous multitasking research. In addition, this study provides definitions of the term task switching, which also has been used to describe human multitasking. The second section of this dissertation focuses on the literature, which characterizes factors and theoretical frameworks of human multitasking research. In this section, human multitasking factors were classified into internal and external factors to analyze factors from the micro to the macro perspective. More detailed definitions and comparisons are also addressed. To summarize and conclude the literature review, this study provides a synthesis framework of internal and external factors of human multitasking contexts. In section III, this dissertation introduces theoretical frameworks that include the constructs of the PAT (Person-Artifact-Task) model and flow model. The next three sections present the research design and two research methods - the experiment and participatory design. The results and discussion section includes the implications of interpreting people's flow experience with motivation, artifact (technology affordance type), and task interconnectedness through the PAT model. The study findings and implications should extend our understanding of multitasking behaviors and contexts and how the interplay of person, artifact, and task factors affects humans' flow experience. A concluding chapter explores future work and design implications on how researchers and designers can take contextual factors into consideration to identify the most effective multitasking in computer-mediated environments.Informatio

Relying on External Information Sources When Answering Knowledge Questions in Web Surveys

Knowledge questions frequently are used in survey research to measure respondents’ topic-related cognitive ability and memory. However, in self-administered surveys, respondents can search external sources for additional information to answer a knowledge question correctly. In this case, the knowledge question measures accessible and procedural memory. Depending on what the knowledge question aims at, the validity of this measure is limited. Thus, in this study, we conducted three experiments using a web survey to investigate the effects of task difficulty, respondents’ ability, and respondents’ motivation on the likelihood of searching external sources for additional information as a form of over-optimizing response behavior when answering knowledge questions. We found that the respondents who are highly educated and more interested in a survey are more likely to invest additional efforts to answer knowledge questions correctly. Most importantly, our data showed that for these respondents, a more difficult question design further increases the likelihood of over-optimizing response behavior
