(4) YA Issues in Society series. Each volume opens with an introduction explaining the title issue. After presenting facts, current statistics, and research, the authors then delve deeper into issues such as the role of video games in violent or addictive behaviors; each book's final chapter explores possible ways to resolve or mitigate problems. Color photos and occasional "Viewpoint" sections add interest to the dense prose and dull, textbook-like layouts. Reading list, websites. Ind. Review covers the following Issues in Society titles: Do Police Abuse Their Powers?, Are Mobile Devices Harmful?, Are Video Games Harmful?, and Is Social Media Good for Society?.

(4) YA Thinking Critically series. Diagrams and sidebars (and one photo per volume) support these well-organized models for classroom discourse. First chapters provide an overview of the debates surrounding medical marijuana and stem cell research; subsequent chapters present pro and con responses to four key questions. Despite lots of graphic elements, the text-heavy pages may be off-putting. Two pages of facts and lists of related organizations are appended. Reading list, websites. Ind. Review covers these Thinking Critically titles: Stem Cell Research and Medical Marijuana.
