Campus Outbreak! - National Center for Case Study Teaching in Science - 0 views

  •  
    This PowerPoint-driven case study follows the progress of three undergraduate students as they attempt to model the rapid spread of an influenza outbreak to determine whether their local newspaper's claim that "40% of the campus has the flu" is accurate. The case introduces epidemiological modeling using a base model for a seasonal influenza outbreak written in the NetLogo programmable modeling environment. In class, students develop tests for the various parameters of the model, run simulations, and evaluate the output. The students then explore the impact of influenza control strategies (vaccination, isolation, and antiviral medications), and finish with the question of whether the continuing outbreak on campus could be a pandemic. The case is written at a basic level for a lower-level undergraduate lecture-style class, but can be adapted to upper-level courses as well. The case was piloted in four different microbiology courses. The simulations stimulated active discussion and the content worked well, whether it was used in a pre-nursing microbiology or upper-level immunology class.

Ebola Evolved Into Deadlier Enemy During the African Epidemic - The New York Times - 0 views

  •  
    The Ebola epidemic that tore through West Africa in 2014 claimed 11,310 lives, far more than any previous outbreak. A combination of factors contributed to its savagery, among them a mobile population, crumbling public health systems, official neglect and hazardous burial practices. But new research suggests another impetus: The virus may have evolved a new weapon against its human hosts. In studies published on Thursday in the journal Cell, two teams of scientists report that a genetic mutation may have made Ebola more deadly by improving the virus's ability to enter human cells.

The Boy in the Temple - National Center for Case Study Teaching in Science - 0 views

  •  
    This interrupted case study examines molecular genetic evidence reported in scientific literature to determine the fate of Louis-Charles, son of Louis XVI and Marie-Antoinette of France. Controversy and rumors surrounding the death of Louis-Charles suggested that either he died as a young boy while being held in captivity by the French revolutionaries or he escaped and was replaced by a substitute who died in his place. One individual claiming to be Louis-Charles was Karl Naundorff. Students begin the case by preparing pedigrees for the descendants of Maria Theresa and Francis I, the Holy Roman Emperor, parents of Marie-Antoinette. The pedigrees can be used to introduce the concepts of alleles identical-by-descent and cytoplasmic inheritance patterns. Students then compare mitochondrial DNA sequences and XY chromosome sequences from hair, bone, heart, and blood samples taken from descendants of Marie Theresa, Karl Naundorff and the heart of the boy who died in captivity to determine if the latter was truly Louis-Charles. An optional PowerPoint presentation with clicker questions is available to help guide the classroom activities.

Genetically Engineered Animals > AquAdvantage Salmon Fact Sheet - 0 views

  •  
    Based on a comprehensive analysis of the scientific evidence, as required by the Federal Food, Drug and Cosmetic Act (FD&C Act), the FDA has determined that AquAdvantage Salmon meets the statutory requirements for safety and effectiveness under the FD&C Act. The salmon are safe to eat, the introduced DNA is safe for the fish itself, and the salmon meet the sponsor's claim about faster growth. Because the sponsor has met these requirements, the FDA must approve the application. The FDA has also analyzed the potential environmental impact that an approval of the AquAdvantage Salmon application would have on the quality of the human environment in the United States and has issued its final Environmental Assessment and Finding of No Significant Impact.

Setting Water on Fire: A Case Study in Hydrofracking - National Center for Case Study T... - 0 views

  •  
    This case study is used to teach undergraduate students about hydraulic fracturing (hydrofracking), a controversial method for extracting methane from shale. The controversy arises from claims that chemicals used in the fracking process and the methane itself find their way into drinking water and are also sometimes found at dangerous levels in the air. The case study begins in a college chemistry class where a student inquires about a news item he saw about residents setting their tap water on fire. The instructor uses this as an opportunity for the students to research hydrofracking and natural gas, and she then integrate these topics into their present study of isotopes. The class first examines what isotopes are by using a guided inquiry based activity. The students then learn how mass spectrometry, which uses the principles just learned about isotopes, is employed to determine the source of methane in contaminated wells. This case study is designed for freshman chemistry students and students in environmental studies.

Data Nuggets - 0 views

  •  
    Data Nuggets are free classroom activities, co-designed by scientists and teachers, designed to bring contemporary research and authentic data into the classroom. Data Nuggets include a connection to the scientist behind the data and the true story of their research. Each activity gives students practice working with 'messy data' and interpreting quantitative information. Students are guided through the entire process of science, including identifying hypotheses and predictions, visualizing and interpreting data, making evidence based claims, and asking their own questions for future research. Because of their simplicity and flexibility, Data Nuggets can be used throughout the school year and across grades K-16, as students grow in their quantitative abilities and gain confidence." Sounds like real science to me!

A Genetic Defense for Murder? - National Center for Case Study Teaching in Science - 0 views

  •  
    This case study presents the mock trial of "Martin Miller." There is no question that Martin killed his girlfriend; he admitted to stabbing her in a violent rage. But what is the degree of his responsibility? By virtue of Martin having the MAOA-L gene variant, together with a history of childhood abuse, should his punishment be reduced? This hypothetical case, which requires students to think through the issues rather than simply look up a verdict, is based on actual events and violent behaviors that resulted in criminal charges claimed to be related to MAOA. The MAOA gene and its effect on behavior have been extensively studied, and research results have been introduced as evidence in court cases with differing results. The present case study allows students to explore how behavioral genetic information can be applied to a courtroom situation, and requires them to integrate information from biology, ethics, and the law. Note: Due to the unusual structure of the case, no answer key is available.

Vaccines, Social Media, and the Public Health - National Center for Case Study Teaching... - 0 views

  •  
    While the "vaccine controversy" has made headlines since the late 1990s, the emergence and popularity of social media has created a public opinion space bursting with pseudoscience, debatable claims and anecdotes regarding the value and importance of childhood vaccines. Because college students get a good deal of news and information from these resources, it is imperative that they distinguish science from pseudoscience and do not perpetuate rumor and falsehoods.  In this case study, written for lower division non-science majors, students will view videos on the scientific method and a mock talk show, analyze data, and scrutinize social media posts.  One of the takeaway points is that if a post/blog/interview identifies a victim, villain, and hero then the student should suspect a story grounded in belief involving pseudoscience.  Following completion of the case, students will hopefully come to conclusions about vaccines based more in the realm of science rather than pseudoscience and continue to apply the scientific method when evaluating social media posts on other scientific topics.

A Cure for Cancer? - National Center for Case Study Teaching in Science - 0 views

  •  
    This flipped case study begins with a video in which a student reveals a family member's diagnosis with breast cancer and then considers the whirlwind of questions that arise in such a situation. Students are asked to relate to the main character and identify what questions they would have and what resources they could consult to seek information.  This sets the context for students to use websites and videos to investigate the nature of cancer, its causes, and progression. Students then learn about the major methods of cancer treatment (surgery, radiation therapy, and chemotherapy), how they work, and the limitations and side effects of each. The case concludes by addressing the claim of one of the characters that there is a conspiracy to hide a cure for cancer. The case would be implemented near the middle of a high school, non-majors, or introductory biology course after discussion of basic cell biology and the cell cycle.
