This research develops three text analytic techniques to improve survey questionnaires. The first is open-ended response mining. Narrative responses on a survey are mined for themes then used to develop new questions. Closed-ended responses identify subgroups who agree/disagree with the question. Then open-ended responses examined for systematic differences which suggest new constructs that dis...

Data-driven systems can provide automated feedback in the form of hints to students working in problem solving environments. Programming problems present a unique challenge to these systems, in part because of the many ways in which a single program can be written. This paper reviews current strategies for generating data-driven hints for programming problems and examines their applicability to...

WebLab-Deusto is a learning environment used at the University of Deusto as the landing platform to several remote laboratories currently used in high school and university level courses. One of these remote labs is VISIR, a remote electricity kit that can be used in teaching DC and AC circuits. As happens in any openended educational environment, it is difficult to assess the learning effects ...

implementation of enterprise resource planning has had a chaotic history in which many projects ended successfully and many failed or ended without approaching the predetermined objectives. this research, in terms of purpose, is considered fundamental since it designs a new system for solving a fundamental problem and it is also an applied research because the research result is deployed in the...

mutual funds are the best tool to mobilize savings and investments in an economy and pakistan is the pioneer in south asia, but this industry is not as much mature in comparison to its age in pakistan. this paper examines the performance of closed ended mutual funds in pakistan by using five different ranking measures during a period of january 2009 to december 2013 and the sample consists of o...

In this paper we present an approach to using empirical data on human teacherlearner interactions to guide the development of a pedagogical agent for supporting musical composition learning. Our approach to bridging the gap between tutorial interaction analysis and computational models, intended for use in learning support systems, is a new one. We support our claim by pointing out that most of...

Over the past five years, Distributed Temperature Sensing (DTS) along fiber optic cables using Raman backscattering has become an important tool in the environmental sciences. Many environmental applications of DTS demand very accurate temperature measurements, with typical RMSE < 0.1 K. The aim of this paper is to describe and clarify the advantages and disadvantages of double-ended calibratio...
