May 13, 2020 · Over the last 25 years, reforms in undergraduate biology education have transformed the way biology is taught at many institutions of higher education. This has been fueled in part by a burgeoning discipline-based education research community, which has advocated for evidence-based instructional practices based on findings from research. This perspective will review some of the changes to ...

1. RNA interference discovered
In the early 1990s, biologists started getting some odd results when trying to manipulate gene expression. The most striking example of this was in a study about petunias. Plant biologists were trying to intensify the red color on the flower petals by introducing a gene that induced the formation of a red pigment, but were surprised to discover that their efforts turned the flower entirely white. These confusing results were popping up in many fields of biology. Andrew Fire and Craig Mello we...
2. Dolly the sheep becomes the first adult mammal cloned
In 1996, scientists cloned a female domestic sheep using adult somatic cells from the mammary glands through the process of nuclear transfer. The resulting sheep, Dolly, matured and reproduced naturally. Dolly was a significant biological breakthroughbecause she demonstrated not only that a full, separate embryo with properly expressed cells of all types could be cloned from a cell taken from a specific part of the body, but also that the cell could come from a fully developed adult. Since Do...
3. Human genome mapped
In 2000, scientists from across the world finished a rough draft of the map of the human genome. The final version was realized in 2003. This biological breakthrough was a difficult accomplishment to reach. It took more than 10 years and contributions from hundreds of scientists. The Human Genome Project reveals in intricate detail exactly what it is that makes us human, showing the placement of every chromosome that contains all the genetic material that makes us who we are. With the informa...
As science and technologies continue to advance, more breakthroughs in biology become possible every day. Some are experiments made possible by new technologies, while others are totally new ideas being explored for the first time. The possibilities with biology are endless. Who knows what we will discover next? Biology will only grow in importance...

Oct 13, 2017 · Biologists have long been concerned about the quality of undergraduate biology education. Indeed, some biology education journals, such as the American Biology Teacher, have been in existence since the 1930s. Early contributors to these journals addressed broad questions about science learning, such as whether collaborative or individual ...

May 17, 2021 · 1 INTRODUCTION. It would be an understatement to say that the field of science education has dramatically changed over the last 100 years. Through wars and geopolitical events, reforms, epistemological, theoretical, and methodological revolutions, and constant work by an engaged community, science education today looks much different than it did in 1920.

The National Science Foundation estimates that 80% of the jobs available during the next decade will require math and science skills, dictating that programs in biochemistry and molecular biology must be transformative and use new pedagogical approaches and experiential learning for careers in industry, research, education, engineering, health-care professions, and other interdisciplinary ...
