Abstract
Temperature loggers can be used in various courses to test hypotheses. Here they were employed to help students develop quantitative skills in a non-majors winter ecology course. Within a forest, student teams each identified two microhabitats in close proximity (e.g., opposite sides of a large tree trunk). They next hypothesized whether or not the thermal environment would differ between the microhabitats. With temperature loggers recording at 0.5-hour intervals for over 75 days, the students amassed vast datasets to test their hypotheses. Prior to their analysis and presentation of the actual data, students participated in two instructional modules to sharpen their quantitative skills.
