In this paper, I describe preliminary work on a new research project in learning analytics at Arizona State University. In conjunction with an innovative remedial mathematics course using Khan Academy and student coaches, this study seeks to measure the effectiveness of visualized data in assisting student coaches as they help remedial math…

A visual regression analysis using the least absolutes method (LAB) was developed, utilizing an interactive approach of visually minimizing the sum of the absolute deviations (SAB) using a bar graph in Excel; the results agree very well with those obtained from nonvisual LAB using a numerical Solver in Excel. These LAB results were compared with…

This article provides evidence from a 4-year longitudinal study on the comparative use of illustrative video podcasts during Economic Geography lectures vis-à-vis traditional educational methods in order to guide pedagogic practice and future research on the relative merits of technology-enhanced learning in higher education. Key benefits derived…

This paper focuses on corrective feedback and examines how trainee-teachers use different semiotic resources to soften feedback sequences during synchronous online interactions. The ISMAEL corpus of webconferencing-supported L2 interactions in French provided data for this qualitative study. Using multimodal transcriptions, the analysis describes…

It is intuitively felt that visual cues should enhance online communication, and this experimental study aims to test this prediction by exploring the value provided by a webcam in an online L2 pedagogical teacher-to-learner interaction. A total of 40 French undergraduate students with a B2 level in English were asked to describe in English four…

Advances in digital technology and a rapidly evolving media landscape continue to dramatically change teaching and learning. Among these changes is the emergence of multimedia teaching and learning tools, online degree programs, and hybrid classes that blend traditional and digital content delivery. At the same time, visual communication programs…

One interesting aspect of teaching students to use PowerPoint and similar graphics packages effectively is that graduate students who are already in the workforce often have bad presentation habits that they need to break. In this article, the author discusses ways of breaking these bad habits. Using storyboards is one way to keep students from…

This paper describes an attempt at evaluating a potentially critical "detail" of teaching practice; that is, using a particular diagram to illustrate the imaging role of a converging lens. This "basic" diagram has been designed to contribute to help students overcome the well-known "travelling image" syndrome. We conducted a comparative study with…

In a litigious society, it is of particular importance that students understand the law of sexual harassment and sexual harassment investigations. Sexual harassment litigation can create a heavy financial burden on employers. Sexual harassment investigations and litigation also cause a social impact on employers. In order to provide students with…

Notetaking is important for recording and remembering class content in most university courses. Despite the importance of this behavior, however, students are often poor notetakers. This study compared undergraduates' notes after traditional lecture, lecture with slides, and lecture with slides plus guided notes. Data on the percentages of…
