Data modeling practices are often invisible to students in introductory biology courses. However, developing a well-rounded understanding of these practices is critical for scientific literacy. Furthermore, introductory undergraduate science laboratory courses are often taught by graduate students or novice instructors with little autonomy,…

Students in a junior- and senior-level Anatomy and Physiology course have the opportunity to correct missed exam questions ("regrade") and earn up to half of the original points missed. The three objectives of this study were to determine if: (a) performance on the regrade assignment was correlated with scores on subsequent exams, (b)…

Quantitative reasoning is a key intellectual skill, applicable across disciplines and best taught in the context of authentic, relevant problems. Here, I describe and assess a laboratory exercise that has students calculate their "carbon footprint" and evaluate the impacts of various behavior choices on that footprint. Students gather…

How can science instructors prepare students for the statistics needed in authentic inquiry labs? We designed and assessed four instructional modules with the goals of increasing student confidence, appreciation, and performance in both experimental design and data analysis. Using extensions from a just-in-time teaching approach, we introduced…

Science literacy involves knowledge of both science content and science process skills. In this study, we describe the Assessment of Critical Thinking Ability survey and its preliminary application to assess the critical thinking skills of undergraduate students, graduate students, and postdoctoral fellows. This survey is based on a complex and…

The development of scientific and quantitative reasoning skills in undergraduates majoring in science, technology, engineering, and mathematics (STEM) is an objective of many courses and curricula. The Biology Department at James Madison University (JMU) assesses these essential skills in graduating biology majors by using a multiple-choice exam…

Both the National Science Education Standards (NSES) and the National Council of Teachers of Mathematics (NCTM) recommend appropriately incorporating mathematics into other disciplines (NRC 1996; NRC 2003; NCTM 2000). With this in mind, an interdisciplinary, inquiry-based project was undertaken to incorporate mathematical analysis of data into a…

Instructional strategies used in teaching oceanographic data collection techniques are discussed. These include having students examine actual data, plan and organize a research cruise on a specific budget, and analyze incomplete data sets. Rationale for using these strategies is included. (JN)

The use of Data Sets in instructional programs as supplements to firsthand experiences is described. A segment of one Data Set related to microbiology is given. (SA)

This laboratory exercise introduces students to a fundamental tool in evolutionary biology--phylogenetic inference. Students are required to create a data set via observation and through mining preexisting data sets. These student data sets are then used to develop and compare competing hypotheses of vertebrate phylogeny. The exercise uses readily…

Data sharing among multiple lab sections increases statistical power of data analyses and informs student-generated hypotheses. We describe how to collect, organize, and manage data to support replicate and rolling inquiry models, with three illustrative examples of activities from a population-level biology course for science majors. (Contains 1…
