In an inquiry-based classroom, student interest is at the heart of curriculum planning, instruction, and assessment. Students are responsible for asking questions, using sources effectively to discover answers, and deciding what format would best present their findings. Aside from creating a sense of ownership, inquiry in the classroom engages…

With the rapid development of wireless communication and sensor technologies, ubiquitous learning has become a promising solution to educational problems. In context-aware ubiquitous learning environments, it is required that learning content is retrieved according to environmental contexts, such as learners' location. Also, a learning content…

The purpose of this study was to investigate medical students' information commitments toward online web medical information. The sample consisted of 534 volunteer medical university students with internet experience from 6 medical universities in Taiwan. This study used the Information Commitment Survey (ICS) for an investigation of medical…

Identifying academic misdemeanours and actual applied effort in student assessments involving practical work can be problematic. For instance, it can be difficult to assess the actual effort that a student applied, the sequence and method applied, and whether there was any form of collusion or collaboration. In this paper we propose a system of…

A model is proposed to explain the retrieval characteristics of an information retrieval system. (Author)

Proposes a system of evaluating information retrieval systems. (PF)

Explores the properties of independent variables in information retrieval systems and defines a class of basic variables named M-factors. (Author/PF)

This report summarizes the work carried out on the automatic construction of keyword classifications and their use in information retrieval. It discusses the possible characteristics of such classifications, and potential ways of using them; and describes the various approaches to classification that were considered in terms of an overall frame of…

The main purpose of the experiment was to answer the question whether broad or narrow terms function most effectively in the retrieval of relevant documents. The answer depends on what the user of the retrieval system wants, his wants being expressed in terms of stated precision-recall preference, or by the exact number of relevant documents he…

Present day shortcomings in information retrieval are the results of a failure to properly contend with the problem of data representation. The index provides the necessary linkage between a multiplicity of sources and a single receiver. Whether considering the source/document-space interface or the query/index interface, the elements of the…

The ability of various Aerospace Materials Information Center (AMIC) information specialists to prepare search strategies for document retrieval was studied by providing ten typical search request statements to seven information specialists. Each specialist prepared search strategies independently. Significant variations occurred among the…

Suggests that a possible reason for receiver-operating characteristics (ROC) curves having a slope other than unity when plotted on Normal-deviate axes is that the dichotomy into relevant and nonrelevant items is artificial, and that there is really a bivariate distribution of objective relevance and relevance as assessed by the information…

This study examined the effectiveness using an automatic algorithm to rank the results of Boolean searches of an inverted file design document retrieval system. Relevant documents were ranked significantly higher than nonrelevant documents on output lists. (Author/KP)

The theory of fuzzy sets is used to provide a rigorous formulation of the problem of associative retrieval. This formulation suggests the idea of using fuzzy clustering to organize data for retrieval. (Author)
