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…

Breathing is something we all do, usually without thinking about it. But when viewed through the lens of physics, respiration becomes an example of elementary thermodynamics. As shown here, the lungs can be modeled as a two-stroke heat engine. Breathing thereby provides a novel physics application for life science students, demonstrating the…

The purpose of this mixed-methods study was to examine the extent to which text condition influences reading comprehension of life science text for 72 4th grade students and to understand their meaning making of each text condition. A three-paragraph passage on the circulatory system was presented in three different diagram types/conditions. All…

This brief review, which is based on a lecture presented at the American Physiological Society Teaching Refresher Course on the Brain and Systems Control as part of the Experimental Biology meeting in 2015, aims to summarize current concepts of the principal mechanisms in the brain that regulate the autonomic outflow to the cardiovascular system.…

This paper explores students and researchers drawings of white blood cell recruitment. The data combines interviews with exhibit of review-type academic images and analyses of student model-drawings. The analysis focuses on the material aspects of bioscientific data-making and we use the literature of concrete bioscience modelling to differentiate…

Senior secondary school students (N = 360), 14- to 18-year-olds, from the Igbo culture of eastern Nigeria responded to a questionnaire requiring them to give causal explanations of biologically adaptive changes in humans, other animals and plants. A student subsample (n = 36) was, subsequently, selected for in-depth interviews. Significant…

The general physics course that is taught in most departments as a service course for pre-med or pre-health students is undergoing a large shift in course content to better appeal to this group of learners. This revision also extends to the laboratory component, where more emphasis is being placed on teaching physics through biological examples.…

Renal clearance, the volume of blood cleared of a substance in a particular time period, is commonly recognized as one of the most difficult concepts in physiology. This difficulty may in part reflect the quantitative nature of renal clearance since many life sciences majors perceive that mathematics is irrelevant to their discipline. Students may…

A fifth grade life science lesson was implemented through a lesson study approach in two fifth grade classrooms. The research lesson was designed by a team of four elementary school teachers with the goal of emphasizing engineering practices consistent with the "Next Generation Science Standards" (NGSS) (Achieve Inc. 2013). The fifth…

The desires of young people and especially young bodies are constructed at the intersections of policies that set the parameters of sex education policies, the embodied experiences of students in classrooms, and the way bodies are discussed in the complex language of science. Moreover, more research points to the lack of scientifically and…

Early childhood educators contribute to the good health of their students every day. By telling students, "Wash your hands" and "Eat your healthy food first," and providing them time to develop gross motor skills through active play outdoors, teachers hope that students will take the advice with them on the way to a healthy and active lifestyle.…

A Framework for K-12 Science Education (NRC 2012) includes inheritance as a core idea within the life science framework. For example, life science core idea 3A states that by the end of second grade, children's knowledge should include the ability to recognize and investigate physical differences and similarities among the same kind of…

Process Oriented Guided Inquiry Learning (POGIL) uses specially designed activities and cooperative learning to teach content and to actively engage students in inquiry, analytical thinking and teamwork. It has been used extensively in Chemistry education, but the use of POGIL is not well documented in other physical and biological sciences. This…

In this article, the author discusses how to tell the difference between a cold and airborne allergy symptoms. A cold is caused by a viral infection. Viruses spread through an infected person's cough, sneeze, handshake, or contact with a contaminated surface. When a virus enters one's body, his/her immune system reacts. This produces the symptoms…

Humans and animals need healthy organs to live. Due to medical conditions and accidents, some organs fail to function properly. For these reasons, the medical community has experimented and can now perform successful organ transplants, allowing patients to continue to live their lives. Many countries have medical programs where individuals can…
