The role of universities in preparing students to use spreadsheet and other technical software in the financial services workplace has been investigated through surveys of university graduates, university academics, and employers. It is found that graduates are less skilled users of software than employers would like, due at least in part to a…

Asking questions is one of the key external indicators of curiosity and a cornerstone of scientific inquiry. To understand the types of questions students ask in an introductory college science class for preservice elementary teachers, students used an online question-ranking tool (Google Moderator) as part of the daily routine. This study…

Mathematics achievement has become vitally important in public education, obligating students to meet and exceed higher standards in spite of ability and knowledge level. This causal-comparative study sought to establish the achievement of the Classworks® supplemental math program with seventh grade students from two public schools in Georgia. The…

The authors' purpose was to determine the effects of computer-based practice and conceptual interventions on computational fluency and word-problem solving of fourth- and fifth-grade students with mathematics difficulties. A randomized pretest-posttest control group design found that students assigned to the computer-based practice intervention…

AutoTutor is a natural language tutoring system that has produced learning gains across multiple domains (e.g., computer literacy, physics, critical thinking). In this paper, we review the development, key research findings, and systems that have evolved from AutoTutor. First, the rationale for developing AutoTutor is outlined and the advantages…

Collaborative systems are widely used today in various activity fields. Their complexity is high and the development involves numerous resources and costs. Testing collaborative systems has a very important role for the systems' success. In this paper we present taxonomy of collaborative systems. The collaborative systems are classified in many…

This article presents the design and evaluation of a tool for inspecting conceptual models of system behaviour. The basis for this research is the Garp framework for qualitative simulation. This framework includes modelling primitives, such as entities, quantities and causal dependencies, which are combined into model fragments and scenarios.…

This dissertation consists of three essays that examine, in three specific contexts, issues related to pricing of information goods and services. As the ability to measure technology resource usage gets easier with increased connectivity, the question whether a technology resource should be priced by the amount of the resource used or by the…

Analysis of ordered binary and unordered binary data has received considerable attention in social and psychological research. This article introduces a Bayesian approach, which has several nice features in practical applications, for analyzing nonlinear structural equation models with dichotomous data. We demonstrate how to use the software…

This article provides background and an introduction to a user-centered design and usability test in an inexpensive format that allows content experts who are novices in e-learning development to perform testing on newly developed technical training modules prior to their release. The use of a small number of test participants, avoidance of…

With the increasing potential for gaming hardware and peripherals to support biometrics, their application within the games industry for software and design should be considered. This paper assesses the ability to use a form of biometric measurement, heart rate, in real-time to improve the challenge and enjoyment of a game by catering it to…

Proving in school geometry is not just about validating the truth of a claim. In the school setting, the main function of the proof is to convince someone that a claim is true by providing an explanation. Students consider proving to be difficult; in fact, they find the very concept of proof demanding. Proving a claim in planar geometry involves…

The purpose of this study was to review and analyze the resources needs and sources of resources and level of training and capacity building in resource mobilization in Kenyan private chartered universities. The study employed a descriptive survey research design. Purposeful sampling technique was used to select 63 respondents (staff) from three…

A child's early language environment is critical to his or her life-course trajectory. Quantitative linguistic feedback utilizes the Language ENvironment Analysis (LENA) technology as a tool to analyze verbal interactions and reinforce behavior change. This exploratory pilot study evaluates the feasibility and efficacy of a novel behavior-change…
