Perceived attitudinal learning in a self-paced versus fixed-schedule MOOC

This study (N = 427) examined perceived attitudinal learning gains (i.e., cognitive, affective, and behavioral learning) related to the course topic by comparing a self-paced version of a Massive Open Online Courses (MOOC) with a fixed-scheduled version. Independent samples t-tests revealed that those in a self-paced classroom were more likely to perceive higher levels of attitudinal learning gains and satisfaction than those in a fixed-scheduled MOOC. Those enrolling in the self-paced course also identified significantly more diverse reasons for enrolling. Learners in both courses identified course videos as the most impactful instructional component. Implications for the design of self-paced MOOCs are discussed.     

Non-positional cell microarray prepared by shape-coded polymeric microboards: A new microarray format for multiplex and high throughput cell-based assays

A non-positional (or suspension) cell microarray was developed using shape-coded SU-8 photoresist microboards for potential application in multiplex and high-throughput cell-based assays. A conventional photolithography process on glass slides produced various shapes of SU-8 micropatterns that had a lateral dimension of 200 μm and a thickness of 40 μm. The resultant micropatterns were detached from the slides by sonication and named "microboards" due to the fact that had a much larger lateral dimension than thickness. The surfaces of the SU-8 microboards were modified with collagen to promote cell adhesion, and it was confirmed that collagen-coated SU-8 microboards supported cell adhesion and proliferation. Seeding of cells into poly(ethylene glycol)(PEG) hydrogel-coated well plates containing collagen-modified microboards resulted in selective cell adhesion onto the microboards due to the non-adhesiveness of PEG hydrogel toward cells, thereby creating non-positional arrays of microboards carrying cells. Finally, two different cell types (fibroblasts and HeLa cells) were separately cultured on different shapes of microboards and subsequently mixed together to create a non-positional cell microarray consisting of multiple cell types where each cell could be easily identified by the shape of the microboard to which they had adhered. Because numerous unique shapes of microboards can be fabricated using this method by simply changing the photomask designs, high throughput and multiplex cell-based assays would be easily achieved with this system in the future.     

The impact of past performance on information valuation in virtual communities: Empirical study in online stock message boards

Unlike other types of virtual communities, individuals participate in online stock message boards for their material needs rather than non-material needs (e.g., sense of belonging). They may seek and read others’ opinions to make better investment performances. The value of information in online stock message boards may vary from person to person according to their past investment experiences. However, little is known regarding how their past investment performance influences the value of others’ opinions. Therefore, our study investigates how individuals process others’ opinions on stock message boards for their investment decisions when they have different levels of past investment performance. We proposed the unique research model with two paths consisting of both online stock message board factors and individual factors to determine continuous use of online stock message boards. We conducted SEM analysis with 452 questionnaire data. The results, first, showed that message boards factors (e.g., satisfaction using others’ opinions) have a positive impact on continuous intention to use while their own satisfaction with past investment activities has a negative impact on continuous intention to use. In addition, we believe that this is one of the few papers to examine the moderating role of self-attribution bias on the effects of stock investment performance. Our results indicated that investors with strong self-attribution bias lower the usefulness of opinions when losing money while they increased confidence in their investment-related abilities when achieving a profit from investment. This study will help to support and extend the theory of IS continuance model while providing practical insights for online stock message board managers by suggesting ways to vitalize online stock message boards.     

Mass media and cultural identity: Issues of ethnic co‐existence in India

This study aimed to analyze the respective effects of cognitive and emotional elements on political judgments, and the effects of media use and political talk on those two elements. Along with the cognitive judgment about political and economic issues/policies, we explored the effect of emotional responses to political and economic situations. During this process, we also looked at the effect of media use and interpersonal communication channels. By analyzing survey data gathered in December 2007, it was first found that voters' cognitive judgment and emotional responses to political and economic situations, respectively, affected their evaluation of the incumbent president. Second, emotional reactions such as ‘pride’ in politics, and ‘hope’ and ‘anger’ for economics, showed significant influence on their evaluation of the president's performance. Third, voters' patterns of media use and interpersonal talk appeared to exert significant influences on those cognitive judgments and emotional responses to political and economic reality.     

Global risk,domestic framing: coverage of the North Korean nuclear test by US,Chinese, and South Korean news agencies

Comparative framing analysis on coverage of the North Korean nuclear test in the US Associated Press, Chinese Xinhua, and South Korean Yonhap news agencies identified four major media packages. First, a common ‘threat’ frame dominated coverage by all news agencies, represented by reconfiguration of geopolitics and an emphasis on global cooperation in both perception and resolution of the nuclear test. Second, with each nation positioning itself differently in the world power system, the issue was notably domesticated in the news, with Associated Press connecting the nuclear test to the broader ‘War on Terror’ framework found frequently in US media, Xinhua promoting a negotiation principle in handling the issue, and Yonhap framing the test with a ‘Cold War’ perspective. In all three cases, national political interests exerted important impacts on the construction of frames. The compatibility of the seemingly opposite packages (globalizing vs. domesticating) signifies both intensification of worldwide social relations and reassertion of national stands. This finding lends support to the transformationalist view of globalization, which suggests that the nation state still matters in a globalized world, but is being recontextualized in a more complex world of politics and culture.     

News use,nationalism, and Internet use motivations as predictors of anti-Japanese political actions in China

Although the rise of nationalistic activism in the Chinese online sphere has drawn much scholarly attention, few studies have examined how nationalism, usages, and motivations of the Internet affect nationalistic actions among general Internet users in China. Using Sino-Japanese diplomatic disputes as a testing ground, this study investigates the effects of news use from traditional and new media, nationalistic attitudes, and motivations for Internet use on anti-Japanese political behaviors such as boycotting and protest participation. Analyses of online survey data revealed that nationalism is positively correlated with information-seeking and social-interaction motivations for Internet use regarding Sino-Japanese disputes. Results also showed that the stronger the motivation for using the Internet to discuss topics associated with Sino-Japanese disputes, the more likely respondents engaged in anti-Japanese behaviors. This study indicates that nationalistic attitudes and motivations involved in the use of new media technologies have significant effects on mobilizing supporters for anti-Japanese actions.     

Teachable-moment-oriented curriculum practice in early childhood education

This study explores aspects of teachable-moment-oriented curriculum practice by questioning whether a teacher's teachable moment is relevant to the learner's 'learnable moment'. For teachable-moment-oriented curriculum practice to result in developmentally and culturally appropriate meaningful learning, transforming the identity between learner and teacher seems imperative. Data collected from naturalistic settings in various teacher education contexts over the last few years are used. Both prospective and in-service teachers' images of teachable-moment-oriented curriculum practices are presented     

Playing at School: An Inquiry Approach to Using an Experiential Play Lab in an Early Childhood Teacher Education Course

Play is considered an important activity of the early childhood years. Research supports the contribution of play to children’s development, learning, and well-being. In spite of this, time for play is being pushed out in many early childhood programs by greater time allotted to formal instruction in narrow academic skills to be tested eventually by standardized tests. As a result, current preservice teachers are likely to see fewer examples of appropriate time and support for play in their field placements in early childhood settings. The purpose of this study was to document and analyze what happens when an experiential play lab is implemented in an early childhood teacher education program. This qualitative study includes multiple forms of data collection, including two forms of reflective writings and group discussions. After the workshop, preservice teachers made a greater number of references to play in their defense of developmentally appropriate practice, and the nature of their references to play increased in their focus on play process and on teacher roles in children’s play, as compared to prior to the lab. The results of this study of an experiential play intervention support its potential as a means of probing, documenting, and enriching students’ understanding of the importance of providing for and supporting play in classrooms for young children.     

EXAMINATION OF EARLY CHILDHOOD PRACTITIONERS’ GENERAL PERCEPTION OF GENDER DIFFERENCES IN YOUNG CHILDREN

This study attempts to explore and discuss preschool teachers’ perception of gender differences in young children through their verbal expression. The teachers (Study I, n —121, Study II, n= 31) in this study perceive female preschoolers as positive and sensitive learners. While many learner qualities such as inventive, problem‐solver, builder, hands‐on, questioning, etc. are identified more often for boys than girls, overall the teachers’ perception of the boys’ group is less “teachable” and “easy to work with” than the girls group. In addition, one of the most intriguing and concerning observations is that girls are perceived as “passive learners” and therefore they are more “teachable” than boys. As implications of the study, the paper discusses an important understanding of gender‐fair and gender‐congruent pedagogical awareness for developmentally and culturally appropriate practice in early childhood education.

This study was originally presented at the 1999 AERA Annual Meeting, April 19‐23, Montreal, Canada, and was titled Examination of Preschool Teachers’ Biased Perception on Gender Difference.     

An Evaluation of Oral Presentation Competency in Interior Design Education

As digital modelling programmes become increasingly prevalent in interior design education, there is concern that graduates are entering the workforce relying too much on strong graphic presentation skills while lacking the basic ability to speak about design. This study explores the gap between practitioners’ perceptions of importance regarding oral presentation competency and students’ perceptions of their oral presentation performances. Additionally, the study explores correlations between in‐class activities and students’ perceptions of their oral presentation competency. Mixed‐methods of investigation include a Delphi study with a panel of interior design practitioners and a survey questionnaire of both practitioners (n = 102) and currently active interior design students (n = 91) in the USA. An Importance‐Performance framework is employed for comparison. Results identify performance criteria for evaluating oral presentation competency and indicate variances between students’ perceptions of their performance and industry perceptions of importance. Furthermore, students’ in‐class activities including studio critiques and written peer assessments show significant correlation with student oral presentation performance indicating activities already frequently incorporated into a design curriculum may have a greater impact on improving performance than specific oral presentation instruction alone.
