Cloud Computing introduces a new business operational model that allows an organization to shift information technology consumption from traditional capital expenditure to operational expenditure. This shift introduces challenges from both the adoption and creation vantage. This study evaluates factors that influence Free/Open Source Software…

Testing is an important stage of teaching as it can assist teachers in auditing students' learning results. A good test is able to accurately reflect the capability of a learner. Nowadays, Computer-Assisted Testing (CAT) is greatly improving traditional testing, since computers can automatically and quickly compose a proper test sheet to meet user…

While physical notebooks and locally saved electronic files are certainly helpful, there are a number of web-based solutions that might be useful to someone conducting research online, or looking to hold their notes in a web-based environment. The main advantage of a web-based note capture tool is that one is able to access it from just about…

Easy A's may be even easier to score these days, with the growing popularity of online courses. Tech-savvy students are finding ways to cheat that let them ace online courses with minimal effort, in ways that are difficult to detect. The issue of online cheating may rise in prominence, as more and more institutions embrace online courses, and as…

The Ancient Greeks studied conic sections from a geometric point of view--by cutting a cone with a plane. Later, Apollonius (ca. 262-190 BCE) obtained the conic sections from one right double cone. The modern approach to the study of conics can be considered "analytic geometry," in which conic sections are defined in terms of distance…

Computerized adaptive testing (CAT) enables efficient and flexible measurement of latent constructs. The majority of educational and cognitive measurement constructs are based on dichotomous item response theory (IRT) models. An integral part of developing various components of a CAT system is conducting simulations using both known and empirical…

The likelihood for generalized linear models with covariate measurement error cannot in general be expressed in closed form, which makes maximum likelihood estimation taxing. A popular alternative is regression calibration which is computationally efficient at the cost of inconsistent estimation. We propose an improved regression calibration…

Researchers in the behavioral and social sciences often have expectations that can be expressed in the form of inequality constraints among the parameters of a structural equation model resulting in an informative hypothesis. The questions they would like an answer to are "Is the hypothesis Correct" or "Is the hypothesis…

This article discusses integrated approaches to the management and preservation of born digital photography. It examines the changing practices among photographers, and the needed relationships between the photographers using digital technology and the archivists responsible for acquiring their born digital images. Special consideration is given…

In March 2019, the EdWeek Research Center conducted an online survey of 700 pre-K-12 teachers to learn more about how they experience and perceive ed-tech innovation. Results suggest that K-12 schools, while not innovation deserts, have plenty of room to grow when it comes to meaningful and positive changes to the ways in which they use technology.

This study investigates the effectiveness of teaching pronunciation with instructional software to a cohort of Chinese learners of English aged 13 to 16 at lower-intermediate level. It also explores the relationship between learners' attitudes towards pronunciation and their pronunciation learning. Participants were 60 students at a language…

This paper presents the "Multi-Role Project" method (MRP), a broadly applicable project-based learning method, and describes its implementation and evaluation in the context of a Science, Technology, Engineering, and Mathematics (STEM) course. The MRP method is designed around a meta-principle that considers the project learning activity…

Problem solving in the field of quantitative composition of solutions (QCS), expressed as mass share and molar concentration, is essential for chemistry students. Since successful chemistry education is based on different mathematical contents, it is important to be proficient in both mathematical and chemistry concepts as well as interconnections…

This study investigated the effects of the storytelling approach on improving of EFL learners' vocabulary knowledge. To this end, 30 upper-beginner EFL learners (out of a population of 134) were selected by means of an OPT test and were assigned to 2 groups: 1 experimental and 1 group. The participants were selected from among young EFL learners…

To understand learners' appropriation of technological tools and geometrical understanding, we draw on the theory of instrumental genesis (Lonchamp, 2012; Rabardel & Beguin, 2005), which seeks to explain how learners accomplish tasks interacting with tools. To appropriate a tool, learners develop their own knowledge of how to use it, which…
