Abstract: This study examined the role of screen size in making inferences about the effects of television content on viewers’ attention, arousal, memory, and content evaluation. Both main and combined effects of two levels of screen size and three levels of content type on the four criterion variables were investigated via a 2x3 mixed factorial-experiment. A total of seventy-five participants were randomly assigned to one of the two screen size conditions (big or small). Those in each condition watched six 2 to 3-minute-long television segments representing three different content types (news, advertising, and entertainment). During the viewing, heart rate and skin conductance (SC) were measured as indicators of attention and arousal respectively. Heart rate data were later converted into beats per minutes (BPM). Skin conductance data were converted into skin conductance response (SCR) and skin conductance level (SCL). After watching, participants completed a questionnaire containing measures of psychological responses to the segments.
The results showed that, with few exceptions, content on the large screen resulted in better memory and was more attention-getting and arousing, as indicated by an cardiac deceleration and an increased SC responses. However, the predicted effect of screen size on participants’ subjective content evaluation did not materialize. Of most importance, viewers’ cardiac and SC responses were most prominent when entertainment content appeared on the big screen, which demonstrated content-specific effects for large screens.

Abstract: There is a general consensus that mathematical content knowledge (M-CK) is crucial for enabling elementary school teachers to effectively teach mathematics. However, it has been suggested that M-CK is not sufficient for elementary school teachers – it must be accompanied by mathematics pedagogical content knowledge (M-PCK). In order to better identify coursework that may promote M-CK and M-PCK, this study investigates confidence of M-CK and M-PCK of elementary preservice teachers (PSTs) who have participated in math content coursework designed specifically for elementary teachers. Findings suggest that participation in these courses positively influences PSTs’ M-CK and M-PCK.

Abstract: In recent years, political communication researchers have examined the potential political implications of social media use in a variety of contexts, but with a focus on the possible effects of social media on political engagement and the extent to which partisans may share or be exposed to political content with which they disagree. In this paper we explore relatively less well-studied questions concerning how social media use may be related to political knowledge. In particular, we examine the ways in which social media use may be associated with political learning among users with relatively lower levels of political interest, drawing on survey data from a sample of U.S. adults collected at the height of the 2012 U.S. presidential election cycle. Our findings suggest that such learning effects, similar to those that have been documented for exposure to political entertainment media, are observable in these data, contingent on a variable that we conceptualize as “feed diversity,” or the extent to which individuals’ social media feeds exhibit diversity in levels of political interest and political perspectives.

Abstract: YouTube is an ideal media for sharing condom advertisements with taboo content. By conducting a quantitative content analysis of 85 different condom advertisements on YouTube over a 24-hour period we found there were no significant differences in the use of humor in the condom advertisements for birth control and disease control versus advertisements that promoted condoms as pleasure aids. Most condom advertisements with the “be prepared” theme did not employ heavy levels of sex.

Abstract: The objective of this study was to understand users’ behaviors and motivations for consuming content and creating content on YouTube. Results from a random-sample Web-based survey of 1,055 students revealed differences between content consumers and non-consumers, and between content creators and non-creators of YouTube when respondents were analyzed according to their demographic profiles and use of other Internet activities, including using Internet, reading news online, reading blogs, using online albums, using podcasts, and creating podcast content. They were also analyzed by news consumption, including digital subscription, online news seeking and traditional media use. The results of open-ended questions of motivation for consuming content and creating content on YouTube showed that content consumers use YouTube mainly for personal fulfillment and information seeking, while content creators make videos mainly for personal fulfillment.
