Although STEM (Science, Technology, Engineering, and Mathematics) has been diversely defined by various researchers (e.g. Buck Institute, 2003; Capraro & Slough, 2009; Scott, 2009; Wolf, 2008), during the last decade, STEM education has gained an increasing presence on the national agenda through initiatives from the National Science Foundation (NSF) and the Institute for Educational Sciences (IES). The rate of technological innovation and change has been tremendous over the past ten years, and this rapid increase will only continue. STEM literacy is the power to “identify, apply, and integrate concepts from science, technology, engineering, and mathematics to understand complex problems a...

Because many patients reduce exercise following outpatient cardiac rehabilitation (CR), we developed an intervention to assist with the transition and evaluated its feasibility and preliminary efficacy using a one-group pretest–posttest design. Five CR patients were enrolled ~1 month prior to CR discharge and provided an activity tracker. Each week during CR they received a summary of their physical activity and steps. Following CR discharge, participants received an individualized report that included their physical activity and step history, information on specific features of the activity tracker, and encouraging messages from former CR patients for each of the next 6 weeks. Mixed model...
