News You Can Use or News That Moves?

This study investigates how journalists covering international humanitarian crises make decisions regarding what types of information to include in stories. Specifically, the inclusion/exclusion of solutions-oriented information is addressed, since crises represent a key time during which the potential for international engagement is discussed in the mainstream media. Interviews with journalists covering hunger crises in Africa reveal an internal tension between maintaining a neutral, unbiased position and writing in a way that supports engagement and action. Ironically, perhaps, journalists find that including solutions-oriented information amounts to unethical and biased coverage, despite the fact that inclusion of solutions to social problems is an accepted and institutionalized aspect of the US news media’s mandate to the public. Reasons for this seeming contradiction are discussed, and I argue that solutions-oriented information not only can be included without demonstrating bias, but that it ought to be included to support ethical coverage that properly informs citizens about potential paths for political engagement.     

Martin to Brown

The rise of the modern Black Lives Matter movement can be traced back to two key events, the 2012 death of Trayvon Martin and the 2014 death of Michael Brown. Research routinely showed that mainstream media’s narrative choices marginalize and delegitimize protesters and their causes, a pattern known as the protest paradigm. This study provides a longitudinal examination of how the same mainstream media system varied in their coverage of similar events and the degree to which journalists challenged the predicted paradigms conceptualized in other academic work. A content analysis of national newspaper coverage revealed that news before the judicial rulings focused on protesters’ tactics (violence versus peaceful) and changed to the realm of ideas (grievances and demands) after the assailants were considered not guilty of wrongdoing. No progression was found in legitimizing coverage of protests between the two cases.     

Measuring Textbook Content Coverage: Efficient Content Analysis with Lesson Sampling

This study addresses measurement issues around a standards-based content analysis of mathematics textbooks’ coverage of standards for use in large-scale monitoring of standards implementation as proposed in a 2013 report by the National Research Council. An earlier study produced an exhaustive content analysis of textbooks using the 2012 Common Core State Standards for Mathematics. This yielded an accurate and reliable portrait of a textbook's coverage of standards. However, such an in-depth analysis is not feasible for large-scale standards-implementation monitoring in which a large number of textbooks may need to be analyzed. To provide such a portrait with sufficient accuracy while also substantially reducing the associated resources needed to produce such a portrait, a simulation study was conducted with the exhaustively coded database to compare different sampling schemes. Results indicated that sampling 1 day from each week and coding the corresponding lessons led to sufficiently accurate representations of the overall content of the textbook. The results provide empirical evidence for large-scale standards-based content analyses of mathematics textbooks for monitoring standards implementation which could be adapted for other subject areas.
