While many university health science programs include physics courses to raise knowledge and understanding of physical science concepts, they are still far from addressing the needs of that science health profession. This study aimed to investigate the effect of an introductory physics course on first-year physiotherapy and rehabilitation (PR)…

In this exploratory study, a sample of 20 four-year-olds took part in structured interviews in order to assess their biological knowledge of how the human body processes a food that they perceived to be fattening. There were two main outcomes to the study. First, the sample demonstrated knowledge of the digestive processes of ingestion,…

This study established whether 12 South African secondary school physics students had incorrect conceptions of basic magnetism and if they had, to what extent they consistently applied such conceptions. Different scenarios in the form of thought experiments were presented in a clinical interview approach. A complex systems perspective underpinned…

Rainfall is a key process in the water cycle, the most structured scientific knowledge about water movement on Earth. Nevertheless, despite being a common topic covered in school science, it entails several cognitive difficulties for young children. This study uses a pictorial task and semi-opened questions to examine primary (11/12 years old) and…

Rapidly occurring advancements in molecular genetics, such as recent developments in epigenetics, are challenging traditional genetics as it is taught at schools. For example, the adoption of epigenetics--which provides molecular mechanisms for the environment to directly alter phenotypic variation--would mean that pivotal tenets in genetics…

Teachers and students struggle with the complexities surrounding the evolution of species and the process of natural selection. This article examines how science teacher candidates (STCs) engage in a clinical simulation that foregrounds two common challenges associated with natural selection--students' understanding of "survival of the…

The purpose of this research was to explore children's understandings of everyday, synthetic and scientific concepts to enable a description of how abstract, verbally taught material relates to previous experience-based knowledge and the consistency of understanding about cloud formation. This study examined the conceptual understandings of cloud…

The biological community is currently undertaking one its greatest scientific endeavours, that of constructing the Tree of Life, a phylogeny intended to be an evidenced-based, predictive road map of evolutionary relationships among Earth's biota. Unfortunately, we know very little about how such diagrams are understood, interpreted, or used…

This research investigates the effect of classroom explicitation of initial conceptions (CEIC) on conceptual change in the context of learning electricity. Eight hundred and seventy five thirteen year-olds were tested in laboratory conditions to see if CEIC is or is not a productive step toward conceptual change. All students experienced a…

The starting point of the present research is the following question: since we live in an age that makes increasing use of visual representations of all sorts, is not the visual representation a learner constructs a window into his/her understanding of what is or is not being learned? Following this direction of inquiry, the present preliminary…

The purpose of this study is to understand in what ways a technology-enhanced learning (TEL) environment supports learning about the causes of the seasons. The environment was designed to engage students in five cognitive phases: Contextualisation, Sense making, Exploration, Modeling, and Application. Seventy-five high school students participated…

Research into children's ideas showed that children's interpretations of natural phenomena often differ from those of scientists. The aim of our study was to identify children's ideas of various age classes (7/8-14/15) about birds. A questionnaire with 31 multiple choice and open ended questions and eight photographs were administered to 495…

Investigates students' responses to presentations of experimental results that conflicted with their preconceptions regarding electric circuits, and how those responses varied according to the type of inquiry skills required to obtain the results. Contains 24 references. (DDR)

Investigates the impact an undergraduate quantum chemistry course has on students' knowledge and understanding of atomic orbitals, molecular orbitals, and related concepts. Analysis reveals that students do not have a clear understanding of these concepts and confuse the various atomic orbital representations. Includes some suggestions and…

Examines both theoretical and practical perspectives on conceptual exchange--exchanging a student's entrenched view on a scientific topic for one based on actual scientific perspective. Endorses the conceptual-mediation model based on interference theory for changing an established view. (AIM)
