This flipped clicker case study explores the fascinating relationship between the Arizona Bark Scorpion (the most venomous scorpion in North America) and the Southern Grasshopper Mouse. Initially it would seem that the grasshopper mouse is no match for the scorpion's venom; however, the grasshopper mouse is easily able to eat the scorpion and is largely immune to the scorpion's sting. By working through this case study, students learn about neuron anatomy and physiology as they explore how the grasshopper mouse is able to survive the scorpion's venom. This case study was developed for an introductory biology course for majors, but it could also be used in an introductory biology course for non-majors or in an anatomy and physiology course. The case requires that students learn basic neuron anatomy and action potential physiology prior to class by reading their textbook or by watching videos on the subjects. An optional set of guided questions tailored to Campbell Biology (10th ed.) is included in the teaching notes.

This directed case study follows two college roommates, Darrell and Anthony, who have just returned to school after winter vacation. They share that their ageing fathers are concerned about their declining faculties and are amused by their fathers' efforts to reverse the process.  Darrell's dad plays "brain games" on the computer while Anthony's father believes running will slow his memory decline. Intrigued, the roommates search through their biopsychology class notes to find out whether their fathers are correct. They review the topics of synaptic formation and plasticity, including axonal and dendritic development, and chemical factors in the brain that promote the survival and growth of neurons or stop the genetically programmed death of neurons. Based on research findings, students reading this case will decide whether Darrell and Anthony's fathers are correct in their assertions. The case is appropriate for a wide variety of courses including introductory anatomy or physiology, or for upper-division biopsychology, biology, or neuroscience courses.

In this "clicker case," students learn about sex determination, meiosis, and chromosomal "crossing over" through the story of Santhi Soundararajan, an athlete from Kathakkurichi, India, who was stripped of a medal at the 2006 Asian Games after failing to pass a sex test. The case is called a clicker case because it combines the use of student personal response systems (clickers) with case teaching methods and formats. The case itself is a PowerPoint presentation (~2 MB) shown in class that is punctuated by questions students respond to using their clickers. It can be adapted for use without these technologies. Developed for an introductory biology class for both majors and non-majors, the case could also be used in an anatomy and physiology course or an endocrinology course.

In this case study, a college student named "Blake" winds up in the emergency room after he experiences a panic attack brought on by drinking a mixture of beverages containing caffeine and alcohol. His panic attack results in a severe episode of hyperventilation. The alcohol he has consumed has the added effect of making the situation worse by impairing Blake's perception and judgement. Through this case study, students learn about acid/base chemistry as they explore hyperventilation, the Bohr effect, the Haldane effect, and how alcohol and stimulants such as caffeine can affect the acid-base balance in the body. This case was originally designed for a flipped classroom, and the associated videos, including one developed by the author, contain foundational information to lead students through basic chemistry and help them connect daily activities to homeostasis and the Bohr effect. Originally written for a general biology course in which general chemistry concepts are discussed, the case could easily be modified for use in an anatomy and physiology course.

This interactive module introduces the anatomy of the immune system and walks through the timeline of a typical immune response.  The timeline includes the differences between the first time a pathogen is encountered versus subsequent infections, including an explanation of how vaccines work. Different tabs, videos, images, questions, and a detailed glossary of terms allow this resource to be explored at varying levels of depth depending on the class. Refer to the "Educator Resources" tab in the Click & Learn for implementation suggestions. 

In this interrupted case study, students shadow an endocrinologist as she tries to determine what is wrong with Angela Barber. Angela is a middle-aged woman presenting with symptoms suggestive of a thyroid issue. Students are given background information, patient history, and results from thyroid-specific blood tests. The exercise emphasizes the hypothalamic-pituitary-thyroid axis and particularly highlights the role of negative feedback. Students will use results from serum thyrotropin and thyroid hormone level tests, as well as patient symptoms, to come up with a diagnosis. In preparation for the diagnosis, students are asked to compare the endocrine profiles of patients with Graves' disease, Hashimoto's disease, iodine deficiency (primary hypothyroidism), and various tumors. The case was developed for college-level biology majors in a physiology course, but also has been used successfully for pre-nursing students in a non-majors anatomy and physiology course. Thus, this activity would be suitable for majors in physiology or pre-medical students, as well as allied health majors.

Loss of species richness is often due to anthropogenic activity. The global decline of amphibians is one such example. This case study examines the impact of road deicing agents on amphibians living near bridges and roads treated heavily with salt during the winter months. Concepts explored in this case include changes to the aquatic environment as a result of road deicing applications, bioaccumulation, osmoregulation in amphibians living in clean freshwater, and the impact of increased aquatic salinity levels on the ability of amphibians to adequately osmoregulate in an environment for which they are not adapted. Three short videos created by the author can be shown in class or assigned for viewing in advance for a "flipped" classroom approach. Originally developed for a general education/introductory biology course, the case could also be used with introductory level animal anatomy and physiology courses as part of a deeper exploration of the renal system.

This case study was inspired by the Zika virus outbreak that occurred around the time of the 2016 Olympic Games. Many athletes were fearful of attending because of the link between Zika virus infection and microcephaly in infants. This concern, however, ran contrary to reports suggesting that the risk of athletes and other travelers becoming infected was remarkably low. Jessica, a fictional Olympic equestrian and the main character of the case, was unfortunately very unlucky and contracted Zika virus near the time of the Games. She ended up enduring negative health complications likely as a consequence of the infection.  This case was designed to be implemented in the nervous system unit of a human biology or anatomy and physiology course. The case is also appropriate for microbiology and public health courses.   Students are expected to have foundational knowledge in viral life cycles, and will explore disruptions in neurotransmission as well as abnormal fetal brain development.

This case study was inspired by a real-life scenario, and follows the story of Roberto, a migrant farmworker whose health is impacted by the usage of pesticides on a farm.  With the help of a health care provider, Roberto becomes aware of the effects of pesticides on his well-being. Students utilize a database and draw conclusions from data in order to answer the case questions.  The case concludes with an activity that uses the "intimate debate" technique in which students use scientific data as evidence to argue whether or not the pesticide under discussion should be banned from usage.  This case was originally developed for undergraduate anatomy and physiology or toxicology courses. Students are expected to have some background knowledge in nerve structure and function as well as the mechanics of neural transmission before starting the case.

In this video Paul Andersen explains the basic anatomy of a neuron; including the dendrites, cell body, axon hillock, axon, and axon terminal. He also describes how neurons are classified both structurally and functionally.

An elderly woman living independently with some help from her family is brought to the local emergency room because she is confused and vomiting. While her son suspects a stroke, a quick battery of laboratory tests indicates that her current problems are the result of impaired kidney function, an old-fashioned home remedy for ulcers, and her prescribed blood pressure medication. The combination of patient- and drug-related factors produces an acid-base disorder responsible for her confusion. This disorder further disrupts her kidney function. The case illustrates secretion and reabsorption processes in the kidney tubule which regulate plasma and urinary electrolytes (including calcium) and pH. The role of bicarbonate in maintaining systemic pH is emphasized. Interactions among the renal, respiratory and nervous systems in the regulation of systemic pH are also illustrated. Further, basic principles of pharmacotherapy and issues related to the appropriate use of medications are introduced. The case was developed for use in a physiology or human anatomy and physiology course, but it might be used in undergraduate nursing courses as well (e.g., pharmacology, pathophysiology).

BioLEAP is a comprehensive educational resource for students who do not wish to take part in classroom dissection exercises, and for teachers and school districts looking to introduce dissection alternatives into their curricula. These "alternatives" are really "advancements" in teaching tools that capitalize on 21st century technologies that can enhance a student's understanding of anatomy, physiology and the life sciences in general. The following links will provide you with cost-effective and humane alternatives to animal use in the classroom, as well as provide you with information about student choice laws and policies that protect students' rights to use dissection alternatives.

For years whale evolution was characterized by speculation and limited evidence. Evolution critics even focused on whales as a means to criticize evolutionary theory. Now whale evolution represents one of the best examples of "macroevolution." This "clicker case" uses this fascinating story of historical irony as a backdrop to the study of whale evolution. First, students study an array of whale fossils to learn how evolution is properly viewed as a branching, relationship-based process, not a linear, progressive, "chain-of-being." Using this view they learn how scientists seek to reconstruct past relationships and study transitional features, not search for "missing links." Students then learn that evidence for macroevolution relies on several lines of independent evidence from fossils, comparative anatomy, embryology, genetics, and paleoecology. With a focus on macroevolution, this case makes a critical contribution to evolution education. It could work well in a lower level undergraduate biology / evolution / paleontology course (non-majors or majors), or in an upper-level evolution course, perhaps early in the semester as a primer for related topics.
