In this article, we review four software packages for implementing propensity score analysis in R: "Matching, MatchIt, PSAgraphics," and "twang." After briefly discussing essential elements for propensity score analysis, we apply each package to a data set from the Early Childhood Longitudinal Study in order to estimate the…

BufCap TOPOS is free software that generates 3-D topographical surfaces ("topos") for acid-base equilibrium studies. It portrays pH and buffer capacity behavior during titration and dilution procedures. Topo surfaces are created by plotting computed pH and buffer capacity values above a composition grid with volume of NaOH as the x axis…

In an age where the world is becoming ever more aware of paper consumption, educators are turning toward technology to cut back on paper waste. Besides the environmental reasons, a paperless music classroom helps students develop their musicianship in new and exciting ways. This article will look at the considerations for setting up a paperless…

This paper shows how it is possible to construct a very simple device for the measurement of magnetic flux densities in an educational context. It is also shown how such a device can be interfaced to a microcontroller with plotting-software to facilitate the study of magnetic fields produced by a current-carrying coil.

Students often find astronomy and astrophysics to be most interesting and exciting, but the Universe is difficult to access using only one's eyes or simple equipment available at different educational settings. To open up the Universe and enhance learning astronomy and astrophysics different planetarium software can be used. In this article we…

The paper also provides the results of the analysis of E-business market research in the Republic of Kazakhstan. The article briefly describes the implementation of a possible solution…

Since being introduced by Connor and Simberloff in response to Diamond's assembly rules, null model analysis has been a controversial tool in community ecology. Despite being commonly used in the primary literature, null model analysis has not featured prominently in general textbooks. Complexity of approaches along with difficulty in interpreting…

This study looks at the change in perception regarding the effect of peer feedback on writing skills using cloud-based software. Pre- and post-surveys were given. The students peer reviewed drafts of five sections of scientific reports using Google Docs. While students reported that they did not perceive their writing ability improved by being…

Transcription of audio data is widespread in qualitative research, with transcription of video data also becoming common. Online data is now being collected using screen-capture or video software, which then needs transcribing. This paper draws together literature on transcription of spoken interaction and highlights key transcription principles,…

In this paper, the authors attempted to evaluate design of leaning units with use of Learning Analytics technique on page flip information. Traditional formative assessment has been carried out by giving assignments and evaluating their results. However, the information that teacher can get from the evaluation is limited and coarse-grained. The…

This case study describes methods and rationales for measuring attitudes toward physical education in high school students. Due to the nature of physical education experiences in schools, there may be both consciously considered (explicit) and less conscious (implicit) forces on attitudes. A full understanding of attitudes toward physical…

The Mobile Access to Supplementary Learning Objects (MASLO) is an open source software kit developed by the Advanced Distributed Learning Co-Laboratory (AADLC) at the University of Wisconsin-Extension. The MASLO kit is designed to provide the components for content authoring and delivery on Apple iOS® and Google Android® smart phones. This project…

In this article, the authors contend that the effectiveness in studying foreign languages by students who are blind can be greatly increased with the use of a properly configured screen reader, Job Access With Speech (JAWS), and a braille display. They assert foreign language instruction should not be limited to auditory input from an instructor…

In this study, we extend previous work on instructors' use of technology by examining how students' perceptions of teacher credibility and affective experience differ depending on how frequently instructors use two common forms of instructional technology: PowerPoint, which is typically used "inside" the classroom; and email, which is…

This article deals with the demands that plagiarism places on academic communities, and with the resources staff possess in dealing with these demands. It is suggested that plagiarism ought to be placed in the context of network of intertwining communities (scholarly, pedagogical and administrative), to which participants are engaged to a…
