Graduates in biology or genetics learn Mendel's laws and Hardy-Weinberg equilibrium as students, and they know, use, and sometimes teach these concepts. However, it is unusual to learn about stochastic processes during the graduate studies of these topics, although the applications of Markov chains in the fields of genetics or biology are…

The present study has two main goals. First, it aims to examine the analogies an instructor uses about "DNA conservation across generations" in a university-level General Biology course. Second, it aims to examine the analogies used in those lessons according to Thiele and Treagust's framework. A qualitative case study design is adopted…

Education in biochemistry teaching laboratories focus primarily on applying biochemical techniques to understanding human disease, biochemistry, and biotechnology. With anthropogenic climate change, there is a renewed interest in quantifying biodiversity, especially with the use of molecular-based approaches such as DNA barcoding. This 3-week…

In theory, there is broad agreement among science education stakeholders that supporting the achievement of scientific literacy is crucial for citizens to make informed and critical decisions about socioscientific issues (SSI). Likewise, it is widely held that argumentation is an important component of scientific literacy. In practice, however,…

Analogies are used to make abstract topics meaningful and more easily comprehensible to learners. Incorporating simple analogies into STEM classrooms is a fairly common practice, but the analogies are typically generated and explained by the instructor for the learners. We hypothesize that challenging learners to create complex, extended analogies…

Learning synthetic biology is often seen as a far distant possibility, restricted to those who have the privilege of an academic career. We propose a student-centered discussion group around synthetic biology, aimed at people from high school onwards with different backgrounds to interact and learn about synthetic biology. We developed a 14-week…

Recent emphasis on learning biology through scientific investigations has focused instruction on understanding and using scientific evidence. To unpack the complexities of evidentiary reasoning, here we present a novel laboratory investigation for teaching the Hardy Weinberg Equilibrium (HWE) in an introductory biology laboratory course that was…

Peer learning is an active learning technique that has been used for students to internalize difficult concepts. We have developed a method of peer learning, a consensus-based education approach, which allows for discussion and class consensus in large lecture classes. We tracked student success on concepts that employed the consensus-based…

In this paper, we propose and describe a new approach, named BarcodingGO, to teach environmental DNA and bioinformatics concepts to undergraduate or graduate students in molecular biology-related fields. The learning pipeline proposed here aims to solve a simulated environmental monitoring problem, in which a biodiversity survey of a particular…

Given the importance of phylogenetic trees to understanding common ancestry and evolution, they are a necessary part of the undergraduate biology curriculum. However, a number of common misconceptions, such as reading across branch tips and understanding homoplasy, can pose difficulties in student understanding. Students also may take phylogenetic…

In the world of higher education, one of the struggles instructors face in the classroom is engaging students in the material. A second discussion in higher education pedagogy is how to weigh content versus activity in the science classroom. How should college teaching be set up when students now have every fact ever found at their fingertips on a…

The real time PCR (qPCR) method provides a powerful method to assess levels of particular species of DNA. When combined with reverse transcription (RT-qPCR) it is the predominate technique to measure expression of gene transcripts. While this approach is very powerful, particular care must be taken in the design of the primers to facilitate…

Students in a mixed majors undergraduate microbiology class often struggle with basic genetics concepts, generating gaps in their overall understanding of genetics. This can be a result of employing the traditional block style of instruction that focuses on teaching skills and concepts one topic at a time. Here I present a simple, yet innovative…

In the spring semester of 2020, colleges and universities adopted online teaching as the primary modality due to campus closure for social distancing. While lectures could be more readily converted to online classes, biology labs were challenging to handle since students could not physically conduct experiments in lab classrooms. In the present…

Concepts of molecular biology and genetics are difficult for many biology undergraduate students to master yet are crucial for deep understanding of how life works. By asking students to draw their ideas, we attempted to uncover the mental models about genes and gene expression held by biology students (n = 23) and experts (n = 18) using…
