In this paper, review and research is made on usability testing in the Geo-information environment, as used in modern digital cartographic visualization. Modern Cartography is more than the presentations of geographical information in a map form. Nowadays, it is seen as Geo-visualization, involving the visual exploration of data by an individual scientist as well as the final presentation to a ...

This study demonstrates that explicit metacognitive training appear to benefit lower achievers’ mathematical word problem solving in a computer environment. 11 to 12year-old Singaporean students in collaborative pairs were assigned to two word problem solving groups. The first group received explicit metacognitive training before word problem solving with WordMath (treatment); and the second gr...

Chapter 1: Introduction: A Hidden World of Nonformal Expert Reasoning This chapter motivates the study of nonformal methods experts use during the process of creative theory formation rather than those they display in polished articles after the fact, and describes the method of video taped think aloud protocols used in this study. The tapes capture scientists in the act of: mentally performing...

EQUALIZATION REVISITED: ITS ROLE AND DESIGN BY ROBIN BOADWAY QUEEN’S UNIVERSITY Introduction Equalization is very much in the news these days. The program is the last vestige of the 1970s’ federal-provincial fiscal arrangements to remain more or less intact over the period of federal retrenchment. As such, it seems to be a sitting duck, a target for potshots from think tanks, pundits, ex-politi...

Users involved in task fulfillment during usability testing undergo layers of affective and cognitive processing which has been of interest to the community of interaction designers. The iterative cycles of User Centered Design process utilize this information from users for the redesign process. Think Aloud, which is the most prevalent Usability evaluation method in practice, has been criticiz...

Historically, mathematics has often been regarded as a role model for all of science – a paragon of abstraction, logical precision, and objectivity. The 19th and early 20th centuries saw tremendous progress. The great mathematician David Hilbert proposed a sweeping program whereby the entire panorama of higher mathematical abstractions would be justified objectively and logically, in terms of f...

Design creativity involves developing novel and useful solutions to design problems. The research in this article is an attempt to understand how novelty of a design resulting from a design process is related to the kind of outcomes, described here as constructs, involved in the design process. A model of causality, the SAPPhIRE model, is used as the basis of the analysis. The analysis is based...

Software metrics have a reputation in industry of not being very useful. I believe one reason for this is that for most metrics one important aspect of them is usually not provided, namely the “entity population model”. In measurement theory, an entity population model defines the typical values for measurements from a metric for a given set of entities. Having these models is necessary in orde...

Test and evaluation of users ́ interaction with computers, oftenemploy Think Aloud. The assumption is that we get access to what goes onin the users ́ minds. But interfaces are multi modal with visualizations as theessential feature, and what happens when users are required to verbalisetheir visual perceptions and interactions? Reflecting upon Think Aloud, weargue that it may ...

Multiword units (MWUs) are critical in processing and understanding texts and have been extensively studied in relation to their occurrences in texts. MWUs also play an essential role in organising vocabulary, which is most prominently visible in domain-specific terminologies. There has been, however, a limited and mostly theoretical concern with the latter aspect of MWUs; researchers intereste...
