Letting Students Control Their Own Learning: Using Games,Role-Plays,and Simulations in Middle School U.S. History Classrooms

The purpose of this article is to synthesize research on the benefits and use of games, role-plays, and simulations, whilst providing examples practicing teachers may wish to use in their classroom. Therefore, the article presents a discussion of key previous research on the use of games, role-plays, and simulations in secondary history classrooms. It also presents a discussion of the benefits games, role-plays, and simulations can have on student learning. This includes discussion of how such student-centered teaching and learning opportunities can improve students' critical thinking, problem-solving, and collaborative skills. Finally, it presents examples of these types of student-centered, inquiry-based, hands-on learning experiences, drawn from the author's previous 16 years of secondary classroom experiences.     

Public relations and artificial intelligence: It’s not (just) about robots

Organizations of all kinds, as well as their in-house or agency public relations teams, increasingly co-opt Artificial Intelligence (AI) to enhance their capabilities. This paper examines a relatively new topic that has received little scholarly attention: the growing relationship between AI and public relations. It outlines several key roles that AI may play in future, based on trends in other industries, and considers the implications for public relations practitioners, their clients and employers. It therefore launches a dialogue about the diversity and extent of AI’s uses in public relations practice. The paper argues that, to date, commentators have placed too much emphasis on AI’s potential for task automation; AI’s broader technological, economic and societal implications for public relations warrant greater critical attention. This does not imply that practitioners need become expert technologists; rather, they should develop a sufficient understanding of AI’s present and potential uses to be able to offer informed counsel.
