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…

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…

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…
