Molecular Workbench vs Pearson Live Response

Molecular Workbench is a free modeling tool for designing and conducting computational experiments across science. Its interactive learning environment supports science inquiry, while its authoring system lets instructional designers create and publish curriculum based on models and simulations. Users can customize simulations or create their own, with topics spanning gas laws, fluid mechanics, states of matter, chemical reactions, genetics, protein synthesis, and quantum phenomena. Activities can include assessments, student-data collection, learning monitoring, and teacher feedback. Simulations can also be embedded in blogs, wikis, or web pages. The Next-Generation Molecular Workbench brings computational experiments to browsers using HTML5. An offline version is available, but it cannot access the latest simulations or collect student data. Downloads are listed for Windows, Mac OS X, and Linux, and require Java Runtime Environment 1.5 or later. The maker says the software needs considerable computing power and may start slowly while the Java virtual machine launches. Molecular Workbench is developed and maintained by the Concord Consortium.

Pearson Live Response is a web-based classroom engagement tool that shows instructors student understanding and participation in real time. Instructors can create, reuse, or adapt sessions, use Pearson content, or build questions with a drag-and-drop planner. Supported formats include multiple choice, written, matching, hotspot, and composite sketch questions. Live charts, word clouds, and visual overlays display responses as they arrive. During a lesson, instructors can pause, discuss, and resend questions, while a scoring slider balances participation and correctness. Geofencing and unique session codes connect participation to the physical classroom. End-of-session reports show class trends, individual responses, and participation levels. Live Response is built into Pearson MyLab and Mastering, and students can join from any device without downloading an app or completing extra setup. Student access through those products costs nothing, with no additional charge. A standalone version is available through Pearson with pricing on request. Current Learning Catalytics users can continue running sessions, and Pearson offers transition-planning help.
