Understanding the functioning of natural systems is not easy, although there is general agreement that understanding complex systems is an important goal for science education. Defining what makes a natural system complex will assist in identifying gaps in research on student reasoning about systems. The goal of this commentary is to propose a…

Solution methods to exact differential equations via integrating factors have a rich history dating back to Euler (1740) and the ideas enjoy applications to thermodynamics and electromagnetism. Recently, Azevedo and Valentino presented an analysis of the generalized Bernoulli equation, constructing a general solution by linearizing the problem…

Purpose: Vocal fold diseases affecting the epithelium have a detrimental impact on vocal function. This review article provides an overview of apoptosis, the most commonly studied type of programmed cell death. Because apoptosis can damage epithelial cells, this article examines the implications of apoptosis on diseases affecting the vocal fold…

This study was conducted to determine the acute changes after the 20 m shuttle run test in the biochemical parameters and heart rates of wrestlers competing in international competitions on a study population of 21 wrestlers. The mean age of participants was 24.14±2.01 years, mean heights 176±0.06 cm, body weight 76.48±14.76 kg, MaxVO[subscript 2]…

Fear, which can be expressed innately or after conditioning, is triggered when a danger or a stimulus predicting immediate danger is perceived. Its role is to prepare the body to face this danger. However, dysfunction in fear processing can lead to psychiatric disorders in which fear outweighs the danger or possibility of harm. Although recognized…

There appears to be an irresolvable disagreement between "progressives" and "conservatives" regarding the ultimate aims of education. This paper argues that the dispute is irresolvable as it currently stands because the traditional progressive/conservative dichotomies are false and based on distorted half-truths. The current…

This review essay affirms the work Mr. Red does with his students to support their learning about evolution and how his approach agrees with the realities of teaching evolution in the American South. It then shows how focusing on understanding, but not necessarily belief, adds to Mr. Red's apparent neutrality a complimentary pedagogical approach…

This research aimed to describe and find out whether implementation of Problem-Based Learning can improve scientific explanation skills in biology learning about the environment. The research method was Classroom Action Research through the implementation of Problem-Based Learning. This classroom action research consisted of two cycles, which were…

This narrative study tells the teaching and learning story of the recently retired Dr. Peggy LePage, a longtime member of the Human Anatomy and Physiology Society with a career as a community college anatomy and biology professor spanning nearly three decades. Drawn from a lengthy narrative interview, this paper describes Dr. LePage's background…

The transition to online learning in spring 2020 was abrupt for both students and instructors. While many instructors moved to asynchronous classes, some institutions relied more heavily on synchronous online courses. Here, we evaluate student perceptions of an inquiry-based molecular biology lecture and lab course following this transition by…

In 2017, Elon University became one of very few universities in the United States without a medical school to have an in-house Anatomical Gift Program (AGP). The program accepts first-person-consenting individuals only and within 2.5 years has become self-sufficient, supporting anatomy curricular needs of its physical therapy, physician assistant,…

Ethics dumping is the practice of undertaking research in a low- or middle-income setting which would not be permitted, or would be severely restricted, in a high-income setting. Whilst Kenya operates a sophisticated research governance system, resource constraints and the relatively low number of accredited research ethics committees limit the…

This study explores how five pre-service subject teachers from different disciplines made sense of and characterized their teacher identity after completing their yearlong pedagogical studies. Leaning on the Bakhtinian dialogical approach and socio-culturally oriented discourse analysis, we examine how the students negotiated multiple voices in…

This article examines the affordances and limitations of textbooks for promoting action competence for sustainable development. Based on a content analysis of Swedish lower secondary level textbooks in geography and biology, we investigated how content about sustainable development is organised and formulated, the ways its multidimensional…

The aim of this study was to determine the effect of a cooperative argumentation model on the listening and inquiry skills and argument level of pre-service science teachers (PSTs). A mixed method was used. The sample consisted of 54 pre-service science teachers. Two experimental groups were studied and the study was conducted in the Special…
