Making the Hidden Explicit: Learning About Equity in K-8 Preservice Science Education     

Tamara Holmlund Nelson 《Journal of Science Teacher Education》2008,19(3):235-254

Preservice teachers in a K–8 science methods course used guided video reflection to examine their interactions with children during science teaching. This inquiry approach helped preservice teachers identify and respond to gaps between their beliefs and intentions about teaching all children and their enactment of those beliefs. The experience of teaching a science lesson and then viewing it multiple times through a critical framework provided an opportunity for preservice teachers to recognize hidden assumptions, unexamined behaviors, and the unintentional meanings they may have conveyed to children. This encouraged them to think more critically about their roles as teachers in creating spaces where all children have access to quality science learning experiences.

Internet Fantasy Violence: A Test of Aggression in an Online Game     

《Communication monographs》2012,79(2):217-233

Research on violent video games suggests that play leads to aggressive behavior. A longitudinal study of an online violent video game with a control group tested for changes in aggressive cognitions and behaviors. The findings did not support the assertion that a violent game will cause substantial increases in real-world aggression. The findings are presented and discussed, along with their implications for research and policy.  相似文献   

中小城市公交视频的发展研究     

沈敏善 《贵阳学院学报(自然科学版)》2012,7(3)

经过多年的发展,公交视频已然成为城市生活的一部分。在公交车的封闭性空间里,公交视频的强迫传播受到了广告主的认可和青睐。然而,当大城市公交视频转身为公交电视的时候,中小城市的公交视频仍然在固步自封,徘徊不前,在他们那里赢利与服务仿佛是＂鱼和熊掌＂不可兼得。  相似文献

“You Don't Play,You Volunteer”: Narrative Public Memory Construction in Medal of Honor: Rising Sun     

Aaron Hess 《Critical Studies in Media Communication》2013,30(4):339-356

Narrative and ludological analysis suggests that Electronic Arts’ Medal of Honor: Rising Sun constructs a narrative of World War II that selectively retells history and constructs an Orientalist representation of the Japanese Empire. The gaming environment exists as an interactive museum that immerses gamers into history so that they experience warfare in their homes. Combining newsreels, fictional letters from home, and interviews with veterans of the “Good War,” Medal of Honor: Rising Sun retells a history that omits details of Japanese internment or atomic weapons. The intertwined themes of personal revenge for the loss of a family member and historical revenge for the attack on Pearl Harbor guide gamers through an “educational” experience of the war. Finally, its failure to simulate violence means that Medal of Honor: Rising Sun invites a critical blindness to commemorating war.  相似文献   

Priming Stereotypical Associations: Violent Video Games and African American Depictions     

Vincent Cicchirillo 《Communication Research Reports》2013,30(2):122-131

The following study examines the influence of racial representations in violent video games upon stereotype associations. Participants were assigned to play either a violent video game with a stereotypical African American avatar or a Caucasian avatar. Following game play, participants completed several measures related to aggression and an implicit association task. The results showed significant differences between the conditions for IAT response times. African American participants showed faster response times to stereotype associations of African Americans than participants who played as a Caucasian avatar. The results also showed a significant interaction effect between participant race and avatar race for aggressive affect.  相似文献

Evolving,Not Extinct: Music Reference in the 21st Century     

Donna M. Arnold 《The Reference Librarian》2013,54(2):146-150

As reference work changes dramatically due to computer technology, tangible reference collections are disappearing from academic libraries in many fields. Such is not the case in music research libraries, however. While many important online music reference resources exist, many print resources remain vitally important, and because of limited funding, they are unlikely to be digitized soon. Music libraries and music reference collections are currently a combination of traditional and online resources, enhanced by human expertise. This beneficial combination should be maintained.  相似文献
