Teaching with core concepts to facilitate the integrated learning of introductory organismal biology.

Despite the call from biology educators for students to learn the biological sciences as a unified whole, the teaching of introductory organismal biology is still largely arranged into separate sections that tend to focus exclusively on the biology of individual taxonomic categories (i.e., animals and plants).

Development and Validation of the Homeostasis Concept Inventory.

We present the Homeostasis Concept Inventory (HCI), a 20-item multiple-choice instrument that assesses how well undergraduates understand this critical physiological concept. We used an iterative process to develop a set of questions based on elements in the Homeostasis Concept Framework. This process involved faculty experts and undergraduate students from associate's colleges, primarily undergraduate institutions, regional and research-intensive universities, and professional schools.

Validating a conceptual framework for the core concept of "cell-cell communication".

We have created and validated a conceptual framework for the core physiology concept of "cell-cell communication." The conceptual framework is composed of 51 items arranged in a hierarchy that is, in some instances, four levels deep. We have validated it with input from faculty who teach at a wide variety of institutional types.

A conceptual framework for homeostasis: development and validation.

We have developed and validated a conceptual framework for understanding and teaching organismal homeostasis at the undergraduate level. The resulting homeostasis conceptual framework details critical components and constituent ideas underlying the concept of homeostasis. It has been validated by a broad range of physiology faculty members from community colleges, primarily undergraduate institutions, research universities, and medical schools.
