This paper presents a study on known approaches for quality assurance of educational test and test items. On its basis a comprehensive approach to the quality assurance of online educational testing is proposed to address the needs of all stakeholders (authors of online tests, teachers, students, experts, quality managers, etc.). According to the…

ARKit is a framework which allows developers to create augmented reality apps for the iPhone and iPad. In a previous study, we had shown that it could be used to detect position in educational physics experiments and emphasized that the ability to provide position data in real-time was one of the prominent features of this newly emerging…

The current study explored two levels of formulaic sequences, general and discipline specific, in a corpus of 200 applied linguistics research articles and examined the functions they serve. Using Antconc software, in total, 2563 sequences were identified including 593 general and 1370 discipline-specific sequences. These numbers account for 30%…

An improvement of the experiment with a driven pendulum is proposed: during a run, the phase shift between the driving force and displacement is continuously displayed vs. frequency. The method of phase measurements is taken from the lock-in detection technique. Using the new PASCO data acquisition system, the measurements in a frequency range…

The costs of higher education continue to rise as budgetary and financial pressures strain universities and its students. In particular, students in the sciences rely on computational software like Wolfram Research's Mathematica in their research and studies. The software and its associated syntax are highly useful tools and are necessary skills…

Single-case experimental methods are used across a range of educational and psychological research. Single-case data are analyzed with a variety of methods, but no statistic has demonstrated clear superiority over other methods. The time-series nature of single-case designs requires special consideration for baseline trend and autocorrelation when…

For many years, multiple representations have played a major role in the teaching and learning of mathematics (NCTM, 2014). The present study defined and investigated a particular phenomenon called representational conflict, which can arise when students simultaneously use multiple representations on the same mathematical task. Representational…

Mobile devices are fast becoming the dominant computing platform for an increasing number of people. Indeed millions of people are using their mobile phones as the main way to access the internet and social and entertainment media. This surge in mobile devices usage has been accompanied by an increase in malware specifically designed to infect…

An interesting Sangaku problem was chosen and a multidirectional study was performed, which included finding the locus of a circle's center moving while being tangent to two circles. It also included finding the radius of that circle given the datum that it is also tangent to the side of an isosceles triangle. Two different proofs are presented of…

Geometrography, "alias the art of geometric constructions" was proposed by Emile Lemoine between the late 1800s and the early 1900s. It consisted originally of a system to measure the complexity of ruler-and-compass geometric constructions, capable of: designate every geometric construction by a pair of values that manifests its…

YouTube is becoming part of popular culture. To explore this advanced advent of technology in learning prospect, this study aims at finding the popularity of the YouTube tutorials among youth, along with their dependency on these videos and their usefulness. The focus of this research paper is on learning skills by watching YouTube tutorial among…

Design-based research argues for the importance of integrating theory with design, but how design decisions are made is rarely documented in educational research. As the interdependence of technology design and education increases, these forms of documentation are becoming more important. To address this need, we present a design narrative…

Background: Both PubMed and Ovid MEDLINE contain records from the MEDLINE database. However, there are subtle differences in content, functionality, and search syntax between the two. There are many instances in which researchers may wish to search both interfaces, such as when conducting supplementary searching for a systematic review to retrieve…

Maturity models fill the need for a measure of overall growth in how outcomes assessment is defined and how feedback informs improvement to meet internal and external expectations at individual institutions of higher education. An exploratory qualitative study was conducted to develop an instrument, the Assessment System Maturity Matrix (ASMM), to…

In this research study, we performed a "content analysis" of selected introductory programming textbooks for three languages to examine which software development concepts are emphasized in these books. Our goal was to determine which concepts are considered to be most representative of software development based on the topics emphasized…
