Collisions Higher Education vs MoleculAR

Collisions Higher Education is a digital game system for teaching and reviewing chemistry in college courses. It aligns with over 55 core concepts in introductory and general chemistry, organized into eight content areas: Radii Trends, Ionization Energy, Acid Strength, Lewis Structures, Ionic Bonding, Energy in Phase Change, LeChâtelier, and IMFs. Each game includes leveled challenges and an exploratory sandbox. Instructors can view student progress and performance in a teacher dashboard, and can use content overviews, quick start guides, formative assessments, and extension assignments. Instructor access is listed at free for US-based college and university educators. Student subscriptions cost $15 a year for a 12-month term; accounts are linked to an instructor’s class, and students register through an invitation URL supplied by the instructor. The product is listed for Android, iOS, macOS, web, and Windows. Playmada has ceased operations, while its FAQ says Collisions HE remains available and free to educators and students as of July 1, 2022. The FAQ also says the company no longer provides email, phone, or training support and directs users to a support forum.

MoleculAR is a free augmented-reality app for chemistry learning on Android and iOS. Users scan QR codes to open three-dimensional models of molecules, molecular geometries, and orbitals, then rotate and zoom them for different views. The app focuses on VSEPR molecular geometry and visualizing complicated molecules. A downloadable QR library provides available structures at no cost. Its reference includes molecules, s, p, d, and f orbitals, plus animations for Newman projection, the SN2 reaction, and ring flip. The maker describes MoleculAR for students and educators in chemistry education and accepts feedback or requests for new molecules by email. The privacy policy says the app does not collect data, while third-party services may collect identifying information. Error logs may include an IP address, device name, operating-system version, and usage date and time. The service does not address individuals under age 13.
