How to Build a Super Predator: From Genotype to Phenotype.

Am Biol Teach 2021 Mar;83(3):138-146

Temple University, Philadelphia, PA 19122.

We present a drawing discovery lab that crosscuts multiple disciplines in biology and links concepts in genetics and evolutionary thinking to enhance understanding of the genotype-to-phenotype transformation. These combined concepts are also linked to ecological frameworks in nature through the model of biological plasticity. Students and teachers explore drawing skills to flesh out the future of a predator while engaging with the computational software MEGA, which introduces students and teachers to nucleotide changes, mutations, variation, phylogenetics, and molecular evolution.

New Approaches in Cancer Biology Can Inform the Biology Curriculum.

Am Biol Teach 2018 Mar;80(3):168-174

Students tend to be very interested in medical issues that affect them and their friends and family. Using cancer as a hook, the ART of Reproductive Medicine: Oncofertility curriculum (free, online, and NIH sponsored) has been developed to supplement the teaching of basic biological concepts and to connect biology and biomedical research. This approach allows integration of up-to-date information on cancer and cancer treatment, cell division, male and female reproductive anatomy and physiology, cryopreservation, fertility preservation, stem cells, ethics, and epigenetics into an existing biology curriculum.

Socratic Seminar with Data: A Strategy to Support Student Discourse and Understanding.

Am Biol Teach 2017 Aug 8;79(6):492-495. Epub 2017 Aug 8.

GSEO;

A Socratic seminar can be a powerful tool for increasing students' ability to analyze and interpret data. Most commonly used for text-based discussion, we found that using Socratic seminar to engage students with data contributes to student understanding by allowing them to reason through and process complex information as a group. This approach also provides teachers with insights about student misconceptions and understanding of concepts by listening to the student-driven discussion. Read More

"Touching Triton": Building Student Understanding of Complex Disease Risk.

Am Biol Teach 2016 01;78(1):15-21

HudsonAlpha Institute for Biotechnology, 601 Genome Way, Huntsville, AL 35806.

Life science classrooms often emphasize the exception to the rule when it comes to teaching genetics, focusing heavily on rare single-gene and Mendelian traits. By contrast, the vast majority of human traits and diseases are caused by more complicated interactions between genetic and environmental factors. Research indicates that students have a deterministic view of genetics, generalize Mendelian inheritance patterns to all traits, and have unrealistic expectations of genetic technologies. Read More

Microbes As Friends, Not Foes: Shifting the Focus from Pathogenesis to Symbiosis.

Am Biol Teach 2015 Nov-Dec;77(9):659-668

GSLC.

Until about two decades ago, the standard method of studying a microbe was to isolate it, grow it in culture, stain it, and examine it under a microscope. Today, new genomic tools are helping expand our view of the microbial world. Instead of viewing them as "germs" to be eliminated, we are beginning to perceive our microbes as an extension of ourselves - an important organ with unique functions essential to our well-being.

Robert M Kao

Am Biol Teach 2014 Oct;76(8):559-562

Center for Developmental Biology and Regenerative Medicine, Seattle Children's Research Institute, 1900 Ninth Ave., M/S JMB-5, Seattle, WA 98101. or .

A major challenge in teaching organ development and disease is deconstructing a complex choreography of molecular and cellular changes over time into a linear stepwise process for students. As an entry toward learning developmental concepts, I propose two inexpensive hands-on activities to help facilitate learning of (1) how to identify defects in heart and kidneys and (2) what evolutionarily conserved strategies from organ development can be applied to understand how to repair these defects. The ease of assembling these activities, combined with traffic flow as a metaphor for physiological function of heart and kidneys, provides students the opportunity to explore and discover biological concepts in organ formation and disease.

Beyond the Central Dogma: Bringing Epigenetics into the Classroom.

Am Biol Teach 2014 Aug;76(6):365-369

Director of GSLC.

Epigenetics is the study of how external factors and internal cellular signals can lead to changes in the packaging and processing of DNA sequences, thereby altering the expression of genes and traits. Exploring the epigenome introduces students to environmental influences on our genes and the complexities of gene expression. A supplemental curriculum module developed by the Genetic Science Learning Center (GSLC) at the University of Utah brings epigenetics to high school and undergraduate classrooms through a range of online and paper-based activities.

A Bioinformatics Module for Use in an Introductory Biology Laboratory.

Am Biol Teach 2012 May;74(5):318-322

ADRIENE ALAIE is Assistant Professor of Biological Sciences at Hunter College of the City University of New York, 695 Park Ave., Room 818N, New York, NY 10065, where VIRGINIA TELLER is Professor and Chair of Computer Sciences and WEI-GANG QIU is Associate Professor of Biological Sciences.

Since biomedical science has become increasingly data-intensive, acquisition of computational and quantitative skills by science students has become more important. For non-science students, an introduction to biomedical databases and their applications promotes the development of a scientifically literate population. Because typical college introductory biology laboratories do not include experiences of this type, we present a bioinformatics module that can easily be included in a 90-minute session of a biology course for both majors and non-majors.

How can plants tell which way is up?

Am Biol Teach 2000 Jan;62(1):59-63

Botany, Miami University, Oxford, OH 45056, USA.

Many people think of plants as essentially sessile organisms that do not actively respond to their environment. What could be further from the truth! In fact, plants are capable of a variety of movements, including the dramatic nastic responses (such as Venus fly trap closure) and the less sensational tropisms. These latter movements are directed growth responses to some type of external stimulus such as gravity (gravitropism, formerly known as geotropism) or light (phototropism). Read More

The evolutionary sequence: origin and emergences.

Authors:
S W Fox

Am Biol Teach 1986 Mar;48(3):140-9, 169

Institute for Molecular and Cellular Evolution, Univ. of Miami, Coral Gables, FL 33134, USA.

The evolutionary sequence is being reexamined experimentally from a "Big Bang"origin to the protocell and from the emergence of protocell and variety of species to Darwin's mental power (mind) and society (The Descent of Man). A most fundamentally revisionary consequence of experiments is an emphasis on endogenous ordering. This principle, seen vividly in ordered copolymerization of amino acids, has had new impact on the theory of Darwinian evolution and has been found to apply to the entire sequence. Read More
