Instructional videos have been increasingly critical to afford effective learning experiences in online courses, but most videos follow a lecturing monolog delivery format. This format tends to lead students to observe the videos passively. Previous laboratory studies have indicated that observing dialog videos of an instructor tutoring a tutee…

The purpose of this research was to investigate the efficacy of professional development in changing two middle school science teachers' questioning to include more questions that require deeper student responses. The professional development was based on ICAP theory which proposes a framework for identifying cognitive engagement based on what is…

This study primarily investigated the role of interactional factors in an unstructured face-to-face collaborative learning environment with challenging engineering activities. We explored dialogue patterns in terms of quality of interaction, students' scaffolding instances, and discourse moves for productive interactions of collaborative dyads in…

Students often have misconceptions about natural selection as they misuse a direct causal schema to explain the process. Natural selection is in fact an emergent process where random interactions lead to changes in a population. The misconceptions stem from students' lack of emergent schema for natural selection. In order to help students…

In laboratory study environments, dialogue-videos, or videos of a tutor and a tutee solving problems together, have been shown to more effectively improve student learning than monologue-videos, or videos of tutors solving problems alone. Yet, few studies have replicated these findings in the context of authentic university classrooms. Here, we…

In 2 separate studies, we found that college-age students learned more when they collaboratively watched tutorial dialogue-videos than lecture-style monologue-videos. In fact, they can learn as well as the tutees in the dialogue-videos. These results replicate similar findings in the literature showing the advantage of dialogue-videos even when…

This article describes the ICAP framework that defines cognitive engagement activities on the basis of students' overt behaviors and proposes that engagement behaviors can be categorized and differentiated into one of four modes: "Interactive," "Constructive," "Active," and "Passive." The ICAP hypothesis…

Instructor-generated videos have become a popular way to engage students with material before a class, yet this is a relatively unexplored area of research. There is support for the use of videos in which instructors tutor students, but few studies have been conducted within the context of a classroom. In this study, conducted in a…

A promising instructional approach corresponds to" learning by observing others learn" (i.e., by watching tutorial dialogue between a tutor and tutee). However, more work is needed to understand this approach's pedagogical utility. Thus, in 2 experiments we compared student learning from collaborative observation of dialogue with 2 other…

Transfer is typically thought of as requiring individuals to "see" what is the same in the deep structure between a new target problem and a previously encountered source problem, even though the surface features may be dissimilar. We propose that experts can "see" the deep structure by considering the first-order interactions…

Prior research on conceptual change has identified multiple kinds of misconceptions at different levels of representational complexity including false beliefs, flawed mental models, and incorrect ontological categories. We hypothesized that conceptual change of a mental model requires change in the "system of relations" between the features of the…

Ohlsson's proposal of resubsumption as the dominant process in conceptual, or nonmonotonic, change presents a worthy challenge to more established theories, such as Chi's theory of ontological shift. The two approaches differ primarily in that Ohlsson's theory emphasizes a process of learning in which narrower, more specific concepts are subsumed…

ICAP is a theory of active learning that differentiates students' engagement based on their behaviors. ICAP postulates that Interactive engagement, demonstrated by co-generative collaborative behaviors, is superior for learning to "Constructive" engagement, indicated by generative behaviors. Both kinds of engagement exceed the benefits…
