Background: Despite anatomically correct models (ACMs) being recommended internationally for their ability to serve as real-life, age-appropriate, and practical models in comprehensive sexuality education (CSE) for learners with visual impairment, there is still limited research exploring South African teachers' views regarding their use.…

Learning about components and processes of complex biological systems is challenging and requires abstraction through mediational tools such as text, visuals, models and visualisation experiences. The 'systems concepts' necessitate building coherent relations and anticipating consequences, requiring greater mediational support. This article…

Purpose: This study presents the development and evaluation of a Constructively Aligned Teaching Sequence (CATS) for teaching the organismal biology of Senior High School. It tried to explore teaching-learning activities and assessment tasks that may be designed to address students' conceptions and teachers' difficulties in teaching organ systems.…

In online educational systems we can easily collect and analyze extensive data about student learning. Current practice, however, focuses only on some aspects of these data, particularly on correctness of students answers. When a student answers incorrectly, the submitted wrong answer can give us valuable information. We provide an overview of…

Making the connection between science and technology might be important for students to learn to identify and solve problems and to acquire scientific knowledge and skills. The research reported in this article concerned the development of a design situation in a science classroom and the study of students performing in this situation. More…

There is an urgent need to increase K-12 science knowledge and STEM (science, technology, engineering, and mathematics) preparedness for college. State and national data suggest a strong correlation between student performance in STEM subjects and student socioeconomic status, race, and ethnicity. Queensborough Community College (QCC) is situated…

Evidence strongly supports a positive, causal effect of physical activity on bone strength and suggests long-term benefits of childhood physical activity to the prevention of osteoporosis. The contribution of healthy bone development in youth is likely to be as important to fracture prevention as the amount of late adulthood bone loss. Families,…

Sex education refers to people's comprehension about sex, which involves not only sexual structure (anatomy, physiology, birth control, pregnancy, etc.), but also sexual relationships concerning human and moral problems. It includes at least sexual physiology, sexual psychology, sexual ethic, sexual law, etc., which aims to help people form the…

Shin splints are a common but often confusing injury. Sources disagree on both the cause of the injury and the anatomical source of the pain. Some blame shin splints on foot pronation, footstrike pattern, or arch height. Regardless of what causes the condition, it affects many runners, beginning in some at a young age. Young runners often have…

Background: Work-related injuries and illnesses in the educational services sector have not been well studied. This analysis examined whether teachers and other school workers are at higher risk of head/chest cold compared to all other workers in the United States. Methods: Seven years (1998-2004) of National Health Interview Survey data on…

While many states mandate some type of sexuality education in schools, state legislation varies widely across the United States. Nevertheless, though much has been written about the behavioral outcomes of sexuality education programs shown to be effective at reducing one or more risky sexual behaviors in teenagers, less is known about the exact…

This article addresses the question of whether early sport specialization provides a "physiological" advantage for future athletic success. It examines the limited literature related to the effects of early specialization on the body's organ systems: the endocrine system, the muscular system, the nervous system, and the cardiovascular system. The…

Chronic pain is persistent and recurrent pain that tends to fluctuate in severity, quality, regularity, and predictability. It can occur in a single or multiple body regions or organ systems. Some of the most frequently reported types of chronic pain include headaches, recurrent abdominal pain (RAP), and musculoskeletal pain. In contrast to acute…

The purpose of this study was to investigate the effects of two learning contexts for explicit-reflective nature of science (NOS) instruction, socioscientific issues (SSI) driven and content driven, on student NOS conceptions. Four classes of 11th and 12th grade anatomy and physiology students participated. Two classes experienced a curricular…

School nurses are faced with the challenge of identifying and treating ankle injuries in the school setting. There is little information guiding the assessment and treatment of these children when an injury occurs. It is essential for school nurses to understand ankle anatomy, pathophysiology of the acute ankle injury, general and orthopedic…
