20 Internet Learning Previous studies have focused on diffuse aspects of virtual learners’ engagement in their education (Marks & al., 2005). Research examining CoI’s social presence dimension of students’ involvement in the learning process usually has been survey-based (see, for example, Williams et al., 2006). It has established meaningful interaction as a prerequisite for other dimensions fully functioning and assigned that responsibility to instructors (Swan & Shea, 2005). Recognizing the essential nature of social presence, this research nonetheless deemphasizes that dimension of the CoI framework by focusing on the instructor’s role in directly conveying the knowledge that students need to absorb. Even the higher-order integration of concepts, an emphasis of CoI’s cognitive presence dimension, is less central to this research because of the quite straightforward nature of the knowledge conveyed. Although greater integration of CoI dimensions is sought (Garrison & Arbaugh, 2007) and is admittedly crucial, this research represents a limited rather than a broad inquiry into the resilience of teaching presence through the web-mediated broadcast. The particular focus on teaching presence separates this inquiry from previous studies based on a synchronous format, which examined students’ performance in multiple dimensions (Clouse & Evans, 2003) or looked broadly at issues of satisfaction, accomplishment (selfreported), and accessibility (Skopek & Schuhmann, 2007). Such broad-gauge research encompasses many elements of learning-based models and involves cross-cutting influences. In contrast, the structure of this course, described in detail below, served to segment the information that was conveyed primarily through lectures, which was the basis for the assessment of student performance. In this way learning that relied on direct instruction could be separately evaluated, apart from the more integrated (and more crucial, from a pedagogical standpoint) learning that occurred in the applied portion of the course, which constituted its core. Methodology The public budgeting course I taught scarcely could be called a hybrid offering, since students could choose, as a sizeable minority did, to attend the class entirely in person. (But the recording of broadcast lectures did make possible the hybridization of an online public budgeting section taught in parallel, as addressed in the penultimate section.) Another unconventional aspect of this design was the lack of a requirement to select a mode of attendance. Students could attend virtually in one class and in person the next, which meant that the virtual and in-person groups were constituted differently from week to week. This mingling of the categories dampened some of the differences that have characterized virtual students in previous research. Departing from the traditional classroom experience minimally—only in providing the option of a web-based medium—served to narrow the factors under consideration. Limiting the outcome of interest to students’ achievement on lecture-based quizzes further restricted the inquiry. Students physically located at home, at work, in libraries, or at other access points, rather than collocated with other students—as is the case for satellite sites linked by dedicated networks, confront different challenges in absorbing traditionally delivered lecture material. For example, virtual students may be subject to distractions far beyond those posed by the classroom. Mechanisms bundled with the software, such as polling, provide the capacity to assess the presence and engagement of virtual attendees, but these would require a greater investment in mastering the technology than this trial required. Indeed, impact on the instructor was kept to a minimum, consistent with the modest level of investments in infrastructure and software. Rather than suggesting this course as a model for distance education, the introduction of web-based broadcasting here tested the feasibility of an affordable, portable configuration for a modestly
