Genetic variation is historically challenging for undergraduate students to master, potentially due to its grounding in both evolution and genetics. Traditionally, student expertise in genetic variation has been evaluated using Key Concepts. However, Cognitive Construals may add to a more nuanced picture of students' developing expertise. Here, we…

Here we build from the central strength of the existing definition of dyslexia--its emphasis on neurobiological origins--and proffer a set of seven core principles for a new, more comprehensive conceptualization of dyslexia. These principles derive from two major research directions: (1) the still evolving history of attempts to explain dyslexia,…

Knowledge about genetics is essential to build a society capable of participating in socioscientific and ethical debates. However, this subject remains difficult for students, making it necessary to develop new educational strategies, such as gamification. Thus, two main objectives are established in this work: (a) to design and evaluate…

Integrating agent-based models (ABMs) has been a popular approach for teaching emergent science concepts. However, students continue to find it difficult to explain the emergent process of natural selection. This study adopted an ontological framework--the Pattern, Agents, Interactions, Relations, and Causality (PAIR-C)--to guide the design of…

The importance of genetic diversity, especially within small populations of endangered species, is becoming increasingly apparent. Genetic engineering techniques that could potentially enhance diversity are now being developed. However, the use of such techniques would require social licence and yet within the general population there is limited…

Textbooks are essential learning resources for both teachers and students, but they often contain misconceptions that can affect students' understanding of key concepts, particularly in biology. Misconceptions can arise from inaccurate or incomplete information, and they may lead to incorrect conceptual understanding. The clarity and accuracy of…

In a typical undergraduate biochemistry course, two main educational objectives include (1) understanding and applying how genetic mutations can influence protein structure and function, and (2) examining metabolic pathways of biomolecules to study cellular storage and fuel. Many times, these topics can seem disparate to students; therefore, we…

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…

Unlike in other countries, heredity and genetics appear first in Spanish science standards in secondary levels. However, some researchers have suggested the need of progressively introducing some basic genetic ideas already from primary education levels. In this context of no formal instruction in early stages, the objectives of our work were to…

Biology education research has shown that deeply rooted intuitions can influence students' understanding of biological phenomena. One example is design teleology, the intuition that organisms' traits were designed to fulfill a goal. Another example is psychological essentialism, the intuition that organisms have fixed essences. Past research has…

Proteins are essential for cell function, and their biological performance depends on three-dimensional (3D) structures. Insulin is made up of 51 amino acids and is a critical hormone involved in glycaemia regulation. In basic education, concepts involving proteins (synthesis, structure, interactions, and function) are abstract and difficult for…

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…

With the better understanding of human genome and genetic contributions to human complex diseases, more and more clinical genetic tests have been developed for the prevention, diagnosis, and treatment of human diseases. This has raised new challenges to classroom teaching of medical genetics (MG) in medical education of undergraduates, who are…

We examined widely used popular calculus textbooks to explore opportunities to learn the limit concept. Definitions, worked problems, and exercise problems were coded to examine if these tasks allow students to use informal thinking to coordinate domain and range processes to understand the infinite process of limit. Results revealed many exercise…

It has been shown that active learning strategies are effective in teaching complex STEM concepts. In this study, we developed and implemented a laboratory experiment for teaching the concepts of Boolean logic gates, molecular beacon probes, molecular computing, DNA logic gates, microRNA, and molecular diagnosis of hepatocellular carcinoma, which…
