Internet-based platforms are increasingly used to collect qualitative data. We conducted a quasi-experimental study to explore whether data collection mode affects data content and data collection costs. Participants (N = 171) were assigned systematically to one of four modes--(1) in-person (control), (2) online video-based, (3) online chat-based,…

Standardized interviewing (SI) and conversational interviewing are two approaches to collect survey data that differ in how interviewers address respondent confusion. This article examines interviewer-respondent interactions that occur during these two techniques, focusing on requests for and provisions of clarification. The data derive from an…

In this case, I discuss my progression from ethnography toward multimodal ethnography as a necessary methodology to study multiliterate and multimodal lives. I view daily life, social interactions, and meaning-making practices as inherently multimodal. By multimodal, I mean that individuals continually read, interpret, and create meanings that…

Elementary students' difficulties with angles in geometry are well documented, but we know little about how they conceptualize angles while solving problems and how their thinking changes over time. In this study, we examined 26 third and fourth grade students completing a body-based angle task supported by the Kinect for Windows. We used…

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…

There has been increasing interest in using of web-based surveys--rather than paper based surveys--for collecting data on alcohol and other drug use in middle and high schools in the US. However, prior research has indicated that respondent confidentiality is an underlying concern with online data collection especially when computer-assisted…

This paper discusses the complexities of investigating the experiences of participants in hybrid (online/offline) learning communities through educational ethnography. In these communities, people construct small cultures in the liminal spaces or "border crossings" between the virtually real and "actually" real, using computer-mediated and…

Microcomputer based laboratory activities have been suggested to have a number of benefits in science education. However, their implementation produces mixed results, and student perception data have in the past yielded responses that are negative regarding the technology. This work presents a case study of three first year undergraduate chemistry…

Historically, responses to the Course Experience Questionnaire (CEQ) were required to be collected by self-administered paper or online questionnaire to be eligible for official analysis. CEQ responses collected by telephone were excluded from the final analysis file to minimise the potential for bias due to mode effects: systematic variation in…

The aim of this article is three-fold: (a) to present an example of best practices in formative assessment in university instruction, offering three different methods of learning and assessment to pass a subject; (b) to analyze differences in academic performance depending on method of learning and assessment chosen; (c) to consider professors'…

Although computer-assisted interview tools have much potential, little empirical evidence on the quality and quantity of data generated by these tools has been collected. In this study we compared the effects of using Virre, a computer-assisted self-interview tool, with the effects of using other data collection methods, such as written responding…
