Research has revealed a significant gap between the thinking patterns and software design habits of students or recent computer science university graduates and those of expert software developers.There may be several causes for this gap, one of which is undoubtedly the fact that throughout their studies students are mostly asked to write software programs of relatively lim-ited scope, and are not usually required to work as part of a team constructing a complex program.In the present paper we will describe a study unit intended to be taught as part of a high school computer science curriculum, which emphasizes the software system aspects. In a study that accompanied the development and actual teaching of the unit, we checked, among other things, whether the students acquired skills for developing a complex software system. 相似文献

This study conceptualizes news bias as a causal factor producing systematic imbalance in the coverage of conflicting sides. Partisan bias is distinguished from structural bias by coverage that systematically favors one side with more prominence and attention. Content analysis was used to compare the television networks' balance in their treatment of Republican and Democratic candidates in stories and segments covering the 2000 and 2004 presidential elections. Presidential candidates received balanced aggregate treatment in both elections. But individual networks differed in their partisan balance. CBS News consistently favored the Democratic candidate in both elections, unlike the mixed results for ABC and NBC. CBS's pattern of imbalance, especially in the 2004 election, suggests a possible political bias in its coverage. 相似文献

TV evening news coverage of the 2008 presidential election by broadcast, cable, and public networks was predominately male and Caucasian in terms of reporters and sources. However, according to our content analysis of 888 campaign stories, viewers saw the least amount of source diversity if they watched the evening news on broadcast networks ABC, CBS, and NBC. Cable networks FOX and CNN, and the PBS evening news had more female and non-White sources. This pattern also holds true for reporter use of nonpartisan sources. Findings on the 2008 election for the traditional broadcast networks are not consistent with those for the 2000 and 2004 elections, when female reporters at these networks had more female and nonpartisan sources in their election coverage than did their male colleagues. Reporters at PBS provided the greatest overall source diversity, regardless of their race or gender, compared to what was observed on broadcast and cable networks. Differences in the way reporters used women and non-White sources to cover the 2008 presidential race may be attributable to organizational factors. 相似文献

Our content analysis of 2,075 campaign stories aired by 3 broadcast and 3 cable networks during the 2004 presidential campaign revealed that female and non-White reporters at broadcast networks were generally more aggressive in their source use when compared to their male and White colleagues, using a greater number of sources and in most cases also allotting the sources more time. Female and non-White reporters at cable networks also tended, although less consistently and to a lesser extent, to use and give more time to female and non-White sources. 相似文献

This study examined how race and gender of reporters and community diversity influenced use of women and minority sources in local television coverage of the 2002 governor's race in Michigan. Content analysis of campaign stories broadcasted by four local television stations revealed that women reporters were more likely than their male colleagues to use women and nonpartisan sources such as experts and ordinary citizens. But minority journalists were only slightly more likely to use minority sources and were less likely than nonminorities to use nonpartisan sources. 相似文献

This study examined context variables (reporter speculation, multiple viewpoints, and story emphasis) and source variables (anonymous sources and source transparency) in broadcast television coverage of the 2004 Democratic presidential primaries. Primary coverage was compared with coverage of other major stories. Primary coverage was no more focused on conflict than were other major stories. Primary coverage was, however, more focused on winners and losers, and primary reporting was more likely to include reporter speculation. Primary stories were just as likely to include anonymous sources as were other major stories, but primary stories also were more likely than other major stories to fully identify sources. 相似文献
