College students (in Experiment 1) and 7th-grade students (in Experiment 2) learned how to design the roots, stem, and leaves of plants to survive in 8 different environments through a computer-based multimedia lesson. They learned by interacting with an animated pedagogical agent who spoke to them (Group PA) or received identical graphics and explanations as on-screen text without a pedagogical agent (Group No PA). Group PA outperformed Group No PA on transfer tests and interest ratings but not on retention tests. To investigate further the basis for this personal agent effect, we varied the interactivity of the agent-based lesson (Experiment 3) and found an interactivity effect: Students who participate in the design of plant parts remember more and transfer what they have learned to solve new problems better than students who learn the same materials without participation. Next, we varied whether the agent's words were presented as speech or on-screen text, and whether the agent's image appeared on the...

Targeted as a highly desired skill for contemporary work and life, problem solving is central to game-based learning research. In this study, middle grade students achieved significant learning gains from gameplay interactions that required solving a science mystery based on microbiology content. Student trace data results indicated that effective exploration and navigation of the hypothesis space within a science problem-solving task was predictive of student science content learning and in-game performance. Students who selected a higher proportion of appropriate hypotheses demonstrated greater learning gains and completed more in-game goals. Students providing correct explanations for hypothesis selection completed more in-game goals; however, providing the correct explanation for hypothesis selection did not account for greater learning gains. From the analysis, we concluded that hypothesis testing strategies play a central role in game-based learning environments that involve problem-solving tasks, thereby demonstrating strong connections to science content learning and in-game performance.

Growing consensus among policy makers and educators alike suggests that our education system must be transformed to address the needs of a global society as well as the needs of the 21st century student. Often overlooked as a resource, students can contribute a valuable perspective on education. The purpose of this study, therefore, was to learn from middle grades students, through surveys and focus groups, what engages them to achieve in school. The findings, which centered on student perspectives of school, uses of technologies in and out of school, and academic engagement, are viewed within the context of global changes and the new demands that this trend places on education.
