Operation Aries! is a computer environment that helps students learn about scientific methods and inquiry. The system has several components designed to optimize learning and motivation, such as game features, animated agents, natural language communication, trialogues among agents, an eBook, multimedia, and formative assessment. The present focus is on a(More)
There is a long history of science fiction novels and movies that feature aliens from other worlds conquering our planet, either overtly as in The War of the Worlds, or covertly as in The Arrival. Aliens have also infiltrated video games, starting with Space Invaders, and more recently with Aliens vs. Predator. Extraterrestrials have also appeared in(More)
Natural language tutoring systems generate significant data during their tutoring sessions, which is often not used to inform real-time, persistent student models. The current research explores the feasibility of mapping concept-focused tutoring sessions to knowledge components, by breaking sessions down into features that are integrated into a session(More)
We investigated predictors of shallow and deep learning for 192 college students with high vs. low prior knowledge in a game-like intelligent tutoring system, OperationARA that has an eText, multiple-choice tests, case-based reasoning, and adaptive tutorial conversations. Students are expected to learn about 11 topics of research methodology across three(More)
Operation ARA is a serious game that teaches scientific inquiry using natural language conversations. Within the context of the game, students completed up to two distinct training modules that teach either didactic or applied conceptual information about research methodology (e.g., validity of dependent variables, need for control groups). An experiment(More)
The current study investigated how interactivity of simulation controls affects data collection in science inquiry. A chemistry simulation was designed to allow either low or high interactivity in setting experimental variables. Adult participants were randomly assigned to one of the interactivity conditions and solved a series of assessment items. The(More)
