This study investigated the effects of individual differences on search strategy using
Internet search tools and the usability of Internet search tools. Thirty subjects from the
University Science Malaysia were pre-tested for cognitive style and problem solving style.
Go ogle, Copernic and Altavista were chosen as search tools in this study. Subjects were
given three-search tasks to perform in controlled conditions. In addition, subjects were
asked to evaluate the usability and relevance for each search tool based on their own
search task. Results showed that individual differences do influence the search strategy for
specific task and specific search tool being used. Field independent and low problem
solving inventory are more active and efficient in their search. Subjects choose Google as
the primary search tool in the future. Therefore, the approach taken in this study is to
understand individual differences involving cognitive and problem solving style, and user
needs in using the advantages of the Internet information retrieval system. Hence the
information retrieval designer and developer can build an optimum presentation structure
and interface for the user
Understanding Cognition Across Modalities for the Assessment of Digital Resources
Drawing from the theories of the cognitive process, this paper explores the transmission, retention and transformation of information across oral, written, and digital modes of communication and how these concepts can be used to examine the assessment of digital resource tools. The exploration of interactions across modes of communication is used to gain an understanding of the interaction between the student, digital resource and teacher. Cognitive theory is considered as a basis for the assessment of digital resource tools. Lastly, principles for the assessment of digital resource tools are presented along with how assessment can be incorporated in the educational practice to enhance learning in higher education
Children’s information retrieval: beyond examining search strategies and interfaces
The study of children’s information retrieval is still for the greater part untouched territory. Meanwhile, children can become lost in the digital information world, because they are confronted with search interfaces, both designed by and for adults. Most current research on children’s information retrieval focuses on examining children’s search performance on existing search interfaces to determine what kind of interfaces are suitable for children’s search behaviour. However, to discover the true nature of children’s search behaviour, we state that research has to go beyond examining search strategies used with existing search interfaces by examining children’s cognitive processes during information-seeking. A paradigm of children’s information retrieval should provide an overview of all the components beyond search interfaces and search strategies that are part of children’s information retrieval process. Better understanding of the nature of children’s search behaviour can help adults design interfaces and information retrieval systems that both support children’s natural search strategies and help them find their way in the digital information world
Investigation of behavior and perception of digital library users: A cognitive style perspective
Cognitive style is an influential factor in users’ information seeking. The study presented in this paper examines how users’ cognitive styles affect their behavior and perception in digital libraries. Fifty participants took part in this study. Two dimensions of cognitive styles were considered: (a) Field Dependence/Independence; (2) Verbalizer/Imager. The results showed that Intermediate users and Verbalizers have not only more positive perception, but they also complete the tasks in effective ways. Implications for the design of personalized digital libraries are also discussed

A Longitudinal Study on the Effect of Hypermedia on Learning Dimensions, Culture and Teaching Evaluation
Earlier studies have found the effectiveness of hypermedia systems as learning tools heavily depend on their compatibility with the cognitive processes by which students perceive, understand and learn from complex information\ud
sources. Hence, a learner’s cognitive style plays a significant role in determining how much is learned from a hypermedia learning system. A longitudinal study of Australian and Malaysian students was conducted over two semesters in 2008. Five types of predictor variables were investigated with cognitive style: (i) learning dimensions (nonlinear learning, learner control, multiple tools); (ii)\ud
culture dimensions (power distance, uncertainty avoidance, individualism/collectivism, masculinity/femininity, long/short term orientation); (iii) evaluation of units; (iv) student demographics; and (v) country in which students studied. This study uses both multiple linear regression and linear mixed effects to model the relationships among the variables. The results from this study support the findings of a cross-sectional study conducted by Lee et al. (2010); in particular, the predictor variables are significant to determine students’ cognitive style
Developing Critical Thinking in online search
Digital skills especially those related to Information Literacy, are today
considered fundamental to the education of students, both at school
and at university. Searching and evaluating information found on the
Internet is surely an important competency. An effective way to develop
this competency is to educate students about the development of critical
thinking. The article presents a qualitative-quantitative survey conducted
during a course in Educational Technologies within a five year Degree
program. The outcomes of the survey reveal some interesting behaviors and
perceptions of students when they are faced with the Web search process
and the characteristics of their critical thinking processes: some aspects
of critical thinking are generally well supported, but others are acquired
only after specific training. Experience shows that if properly motivated by
metacognitive reflections and a clear method, students can actually critically
evaluate the information presented online, the sources, and the sustainability of the arguments found. Positive results also occurred when the evaluation process was done in a collaborative modality
Mathematical practice, crowdsourcing, and social machines
The highest level of mathematics has traditionally been seen as a solitary
endeavour, to produce a proof for review and acceptance by research peers.
Mathematics is now at a remarkable inflexion point, with new technology
radically extending the power and limits of individuals. Crowdsourcing pulls
together diverse experts to solve problems; symbolic computation tackles huge
routine calculations; and computers check proofs too long and complicated for
humans to comprehend.
Mathematical practice is an emerging interdisciplinary field which draws on
philosophy and social science to understand how mathematics is produced. Online
mathematical activity provides a novel and rich source of data for empirical
investigation of mathematical practice - for example the community question
answering system {\it mathoverflow} contains around 40,000 mathematical
conversations, and {\it polymath} collaborations provide transcripts of the
process of discovering proofs. Our preliminary investigations have demonstrated
the importance of "soft" aspects such as analogy and creativity, alongside
deduction and proof, in the production of mathematics, and have given us new
ways to think about the roles of people and machines in creating new
mathematical knowledge. We discuss further investigation of these resources and
what it might reveal.
Crowdsourced mathematical activity is an example of a "social machine", a new
paradigm, identified by Berners-Lee, for viewing a combination of people and
computers as a single problem-solving entity, and the subject of major
international research endeavours. We outline a future research agenda for
mathematics social machines, a combination of people, computers, and
mathematical archives to create and apply mathematics, with the potential to
change the way people do mathematics, and to transform the reach, pace, and
impact of mathematics research.Comment: To appear, Springer LNCS, Proceedings of Conferences on Intelligent

The Effectiveness of Case-Based Reasoning: An Application in Sales Promotions
This paper deals with Case-based Reasoning (CBR) as a support technology for sales promotion (SP) decisions. CBR-systems try to mimic analogical reasoning, a form of human reasoning that is likely to occur in weakly-structured problem solving, such as the design of sales promotions. In an empirical study, we find evidence that use of the CBR-system improves the quality of SP-campaign proposals. In terms of the creativity of the proposals, decision-makers who think highly divergent (i.e., who tend to generate many, and diverse ideas in response to a problem) benefit most from prolonged system usage. Creativity, in turn, is positively related to the (practical) usability of a proposal. These results suggest that the CBR-system is most effective when it is used as an idea-generation tool that reinforces the strength of divergent (creative) thinkers. A convergent thinking style, in which case the CBR-system has a compensating role, even has a negative impact on CBR-system usage. Increasing the decision-maker's personal belief in the usefulness of the system, e.g., by training or education, may help to alleviate this reluctance to use the CBR-system.marketing management support systems;sales promotions;case-based reasoning;weakly-structured decision making
