对数学“公开课”的几点思考

现阶段公开课“造假”现象严重，使课堂教学失去了真实性：导向上出现了偏差，应从由重“受术”到重“就道”，由看重“教”到看重“学”，由重“观摩”到重“研讨”三个变化入手，从学生发展及学科特点出发，摒弃“造假”，还课堂教学以真实。

A Model for Quantitatively Analyzing Representations of Social Class in Screen Media

Content analyses of prime-time television provide a picture of predominant cultural stereotypes and social trends. The present research is a quantitative content analysis of social class in popular broadcast and cable television in the United States. This research advances scholarship by systematically analyzing character class in addition to more commonly examined variables such as race and gender. A model for the operationalization of class for quantitative content analyses of mediated texts is offered. This proof of concept study demonstrates the viability of studying media representations of class quantitatively to systematically document patterns of portrayal.     

The effect of television viewing on ethnic prejudice against immigrants: A study in the Italian context

Television viewers construct many different meanings from the programs they watch. Here, we investigated whether ethnic prejudice is differentially influenced by the genre of television programs in their portrayal of ethnic minorities. We also wanted to determine whether a higher educational level reduces ethnic prejudice and television use. A self-reported questionnaire was administered to 401 Italian adults. Structural equation modeling was used to analyze the relationships between ethnic prejudice and television program contents and educational level. Viewing Reality and Variety Shows was positively related to ethnic prejudice, News and Public Affairs was negatively related, and Films and TV series had no apparent influence on prejudice. Educational level was negatively related to both ethnic prejudice and watching Reality and Variety Shows, and positively related to viewing News and Public Affairs and Films and TV series programs.     

Realism Matters: The Role of Perceived Realism in The Biggest Loser

This study investigated implications of viewing The Biggest Loser, NBC’s popular reality television show. Using online survey data collected from 613 participants, results suggest that exposure to the program is positively associated with perceived realism of the program, which in turn is positively associated with developing internal weight locus of control. Meanwhile, internal weight locus of control is positively associated with audience members’ exercise behavior, meaning the higher level of internal weight locus of control the audience members develop, the more likely they are to engage in physical exercise. This study offers evidence that health-related reality television might be a useful tool to influence audience members’ cognitions on health issues, which could potentially lead to healthy lifestyles.

《西游记》陈评李评本中的"虚实论"研究

壮怀卓荦谁知己,放眼悲歌我独狂——论周婉如诗歌的悲剧意识

周婉如是晚清黔西北有名的女诗人,她才华横溢、心怀壮志,有着当时闺阁中人所不及的胸怀和气质。但诗人生不逢时,那个时代没有给一个女性提供驰骋壮志的机会,她只能郁郁地在闺阁中终老一生。理想与现实的激烈冲突,造成了周婉如的人生悲剧,体现在她的诗歌中,就表现出身束闺阁、功业难成和知音难寻、青春易逝所产生的悲愤和忧愁,虽然她的诗歌中也有一定的悲剧意识的消解因素,但并没有起到消解的作用,反而使她的悲剧意识得到加强。
