Knowledge of scientific principles and practices is vital to creating informed citizens. At its core, science helps create citizens who question the why and how of things, while also increasing knowledge of the world and beyond. Humans by nature are curious and thrive when they are engaged in learning that relates to real-world situations relevant…

Water is one of the most common molecules in the universe. Water is polarized, but it has many states besides the normal tetrahedron depicted in standard biology texts. Water is also the most ubiquitous molecule on Earth, the universal solvent. It is the internal and external habitat of cells. Ecologically, water is contiguous with life and the…

Modeling is a core practice in science and is a meaningful way to learn the subject. This article introduces a modeling-based approach that highlights the idea that modeling is an iterative process and integrates the fundamental parts of scientists' work and key suggestions for teaching through modeling. The lesson "The Structure and Function…

This paper catalogs previous articles in "American Biology Teacher" on various aspects of teaching about science misinformation and identifies which of the core concepts are addressed in each. A concise overview of relevant themes is provided, along with how the concepts align with the Next Generation Science Standards. This may serve as…

Evolution is the central concept of biology and key to a comprehensive understanding of any complex biological interaction. It has proven to be a particularly difficult subject for both teachers and students. Hybrid teaching environments have the potential to support students in learning about complex topics and simultaneously enable researchers…

When students think of evolution, they might imagine T. rex, or perhaps an abiotic scene of sizzling electrical storms and harsh reducing atmospheres, an Earth that looks like a lunar landscape. Natural selection automatically elicits responses that include "survival of the fittest," and "descent with modification," and with…

Especially within the light of the current loss of biodiversity, we want our students to gain a better understanding of the issues at stake in order to take action and support plants and their pollinators. Many educational approaches focus on honeybees, disregarding the vast diversity in the context of pollination systems and the complex…

Although unrecognized for his scientific achievements during his life, Gregor Mendel pioneered our modern understanding of the gene, work that shaped the field of genetics and advances in biology and medicine. The field that he set in motion 200 years ago lies at the center of current ethical debates about the future of humanity, the limits of…

In 1900, three botanists claimed they had found regularities in inheritance, which soon would be known as Mendel's Laws, without knowing the work of Gregor Mendel or of each other. Their claims of independent (re)discovery have been thoroughly studied during the past decades, with various outcomes. The case is still of interest today as it offers…

The recent discovery of preserved cells and soft tissues in certain dinosaur bones seems incompatible with an age of millions of years, given the expectation that cells and soft tissues should have decayed away after millions of years. However, evidence from radiometric dating shows that dinosaur fossils are indeed millions of years old. Under…

Concepts relating to enzymes and energy are central to understanding chemical and biological processes at the molecular level. Student learning of these crosscutting concepts can be challenging, so it is important to identify misconceptions and remediate them early, especially in introductory classes. Here we describe an activity in which…

The purpose of this research was to determine the effect of the 5E model on the understanding of the molecular genetics concepts taught in general biology. The research had a quantitative focus and a quasi-experimental design, and the participants were 40 undergraduate students from a private university in the west of Puerto Rico, which were…

Evolutionary theory is fundamental to biology, yet evolution instruction in high schools has often been unsatisfactory. How or whether high school biology teachers teach evolution is influenced by their own acceptance or rejection of evolutionary theory, parents' and community members' views, and in the case of some private schools, their…

Productive struggle is a process in which students expend effort to grapple with perplexing problems and make sense of something that is not immediately apparent and beyond their current level of understanding and capacity. The experience encourages students to reflect on and restructure their existing knowledge toward a new understanding of…

There is an emphasis on survival-based selection in biology education that can allow students to neglect other important evolutionary components, such as sexual selection, reproduction, and inheritance. Student understanding of the role of reproduction in evolution is as important as student understanding of the role of survival. Limiting…
