In studying online learning, researchers should examine three critical interactions: instructor-student, student-student, and student-content. Studentcontent interaction may include a wide variety of pedagogical tools (e.g., streaming media, PowerPoint, and hyperlinking). Other factors that can affect the perceived quality of online learning include distance education advantages (e.g., work and family flexibility) and antecedent personal characteristics (e.g., experience and gender). The study indicated that instructor-student interaction is most important, twice that of student-student interaction; that some student-content interaction is significantly related to perceived learning; that antecedent variables are not significant; and that distance education advantages/flexibility, although significant, are less important than other interactions.

The free paper is a convenient and relevant advertising information source, performing the functions of providing surveillance information and product values to consumers. Several market segments with varying market attributes are identified as heavy readers of the free paper. Based on the theoretical framework of uses and gratifications, a multivariate model helps to explain readership. Readership of the free paper increases as age increases, as involvement in some leisure lifestyles increases, as more favorable attitude toward the free paper increases, and as the value of information on homes and equipment and on food and supplies increases.
