Through research and personal experience, we have found that the most crucial factors determining who succeeds with clicker-based teaching, who gives up, and who merely muddles along have far more to do with instructors' deeper attitudes, models, and professional thought habits than with which "best practices" they try or what support they…

Many varieties of data acquisition systems are now available for science classrooms. Most systems consist of a range of sensors--typically called probeware--connected to an interface unit usually described as a datalogger due to its capacity to record data from these sensors. Although some systems operate independently, most units connect to a…

Probeware is increasingly being implemented in science classrooms because it is less expensive than it used to be and improvements in hardware and software have made it more accessible to students and teachers. Many probes or sensors can now simply be connected to a computer, calculator, or other handheld device, and will immediately begin to…
