Analogies are useful tools for teaching difficult scientific concepts and clearing up learners' misconceptions. However, if not properly used, they can lead to further misconceptions. More importantly, little is known about how science teachers use analogies in Nigerian classrooms. This study assessed science teachers' use of analogies by…

Traditional biology curricula depict science as an objective field, overlooking the important influence that human values and biases have on what is studied and who can be a scientist. We can work to address this shortcoming by incorporating "ideological awareness" into the curriculum, which is an understanding of biases, stereotypes,…

A task force of physiology educators from 25 Australian universities generated an Australia-wide consensus on seven core concepts for physiology curricula. One adopted core concept was "cell membrane," defined as "Cell membranes determine what substances enter or leave the cell and its organelles. They are essential for cell…

Many molecular biology and biochemistry instructors have altered their classroom behavior in favor of evidence-based, active learning instructional strategies. Overwhelming evidence confirms that lecture-only classrooms are detrimental to student learning outcomes, but we know less about the impact textbooks have on students outside the classroom.…

Approaching elective courses and courses on special topics in Chemistry can seem daunting at times, given the varied backgrounds of the students, together with the broad nature of topics. Often, institutions may give incentives for creating sustainability related course offerings, but knowing where to start and how to organize the information…

Evolution is central to biology education and yet, it is often one of the most misunderstood and controversial topics that biology educators must teach. Research spanning the last four decades has shown that students continue to struggle, even with direct instruction, to understand the process of evolution by natural selection. In my first…

As implementation of green chemistry into university-level courses increases, it is vital that educators have a tool to rapidly measure student knowledge of green chemistry principles. We report the development of the Assessment of Student Knowledge of Green Chemistry Principles (ASK-GCP) and evaluation of its sensitivity and effectiveness for…

We describe a novel, university-level, introductory biology course that uses evolution as a narrative framework. Our course conveys the content in an introductory biology course by telling the story of the evolution of life on Earth. We begin with early Earth environments in which biological molecules and processes evolved and led to the first…

Climate change science is complex and perceived to be controversial in nature by some stakeholders. Yet from the perspective of educators and policy makers, climate change science is an important topic to be taught in secondary science education. The presence of controversy can influence teachers' instructional decisions and cause confusion about…

This qualitative action research study examines how middle and high school STEM teachers create and implement lessons that connect concepts to the real-world and develop student metacognition. The researcher collected data through interviews, focus groups, document analysis, and survey questions. Participants from vocational, private, and…

Many researchers have suggested that incorporating history and philosophy of science in the science curriculum can be helpful for students' understanding of scientific concepts and effective for developing their scientific thinking. Recently, in this context, there have been studies on historical controversies which show that history of science…

Entropy is a concept with an extreme controversy which many scientists have been trying to explain. Some of the approaches employed in its definition contradict each other, which made it extremely difficult for high school and college students to understand. Boltzmann was the first person who brought a statistical explanation to entropy and…

This review explores Thomas Lessl's "Demarcation as a classroom response to creationism: A critical examination of the National Academy of Science's "Science, Evolution, and Creationism" (2008)." Lessl's work examines philosophical debates about the relationship between science and religion from the perspective of communication…

As a science teacher and youth minister from a predominantly white evangelical community in rural Appalachia, I have had many opportunities to teach the science of global warming to climate change deniers. In this manuscript, I share some of the lessons I have learned to make my presentations less contentious and help those I teach be more…

Introductory chemistry textbooks often present valence bond (VB) theory as useful, but incorrect and inferior to molecular orbital (MO) theory, citing the electronic structure of O[subscript 2] and electron delocalization as evidence. Even texts that initially present the two theories on equal footing use language that biases students toward the…
