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…

The COVID-19 pandemic necessitated changes in educational strategy, including modification of assessments. Students in the Master of Biomedical Sciences (MBS) program at Duke University School of Medicine are required to take a course entitled "Organ Systems" (OS), which includes organ histology. In pre-pandemic circumstances, cumulative…

Even though genetics has been implemented in biology curricula at secondary schools for decades, reports repeatedly indicate that students still hold various misconceptions about this topic. To successfully target these misconceptions, we need to know their nature and origin. We aimed to investigate these properties in the Czech educational system…

This study reports on the theoretical- and empirical-based design and evaluation of cell membrane biology learning activities within the Model of Educational Reconstruction and experiential realism. First, we designed analogy-based learning activities by considering students' and scientists' conceptions as described in the literature. Secondly, we…

In this paper, a self-created analogy is presented based on comparing the process of osmosis with a situation recreated in a train carriage. It was implemented with upper-secondary education students at a secondary school in Chiclana de la Frontera (Cádiz, Spain). To assess the progression of the students' models on osmosis, their activities…

This article outlines the results from the research on primary and secondary school pupils' conceptualisation of microorganisms. It has been observed from the past few decades that one conceptual model is dominant, in which microorganisms are considered harmful, disease-causing and living in dirty environments. These misconceptions are only likely…

Research into seed germination classroom activities has been common in the last few decades. Didactic proposals have generally focused on the implementation of guided activities in a specific educational stage and context, and an evaluation of the results. However, it is not evident that students approach seed and germination concepts with a…

Plant leaves are green because they contain the green photosynthetic pigments, chlorophylls a and b. Popular science literature, and sometimes even textbooks, state that the greenness is caused by reflection of green light by chlorophyll. In the present study, we compared the reflectance spectra of green leaves to yellow or white leaves of the…

Many evolutionary anthropologists view cooperation as core to the evolutionary success of our species. Concurrently, many sustainability scientists view cooperation as core to the future sustainable development of our species. When it comes to biology education, however, it is unclear how or if students are being engaged in these scientific…

The digestive system (DS) is a fundamental topic in biological science teaching. However, the literature indicates that students have difficulties in learning about it. In the present work, we focus on how early childhood Pre-Service Teachers (PSTs) develop their understanding of the DS regarding the CMP (Components-Mechanisms-Phenomena) framework…

A complex terminology developed around the evolutionary concept of adaptation. One definition of adaptation is synonymous with adaptive evolution and denotes a process of population change driven by natural selection resulting in individuals better able to survive and reproduce in a particular environment (compared to the population before the…

This study aims to determine misconceptions about interphase, a basic phase in the cell cycle and to address those misconceptions. Meristem cells in plants, stem cells in animals, spermatogonia and oogonia cells, and some cells with partial regeneration ability do not lose dividing ability. However, normal tissue cells other than these are in the…

This study aimed to facilitate grade 8 students' conceptual understanding of 'sustainable development (SD)' via Common Knowledge Construction Model (CKCM)-oriented instruction. Through a pre-experimental research approach, the study was conducted with 31 grade 8 students drawn from a secondary school in the city of Trabzon, Turkey. A word…

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…

Recently, the COVID-19 pandemic impacted immensely on individuals and societies around the world. This study aimed at delineating Swedish middle school (10-12-year-old) pupils' understanding of bacteria and viruses, thereby illustrating the influence of the pandemic at schools and in society. Data was collected by semi-structured, individual…
