The research compares teachers' and their pupils' performance on plant nutrition. The misconceptions of 89 primary school children from one state school have been compared with those of their four teachers. A questionnaire and a drawing task were used for data collection. The results evidence that children and teachers have serious shortcomings…

The purpose of this study was to investigate knowledge of high school students related to conductors at electrostatic equilibrium and electric field lines. The descriptive model was preferred in line with the purpose of the study. The sample of the study consisted of 35 11th grade students, 18 females and 16 males, who were enrolled in a…

Practices such as astrology or crystal healing can be defined as pseudoscience. Against pseudoscience, one of the major responsibilities of science education must be to develop science-literate individuals who are able to understand what science is, how science is undertaken, how scientific knowledge is constructed, and how it is justified, then…

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…

This article describes an investigation into teaching and learning with student-generated animations combined with a representational pedagogy. In particular, it reports on interactive discussions that were stimulated by the students' own animations as well as their critiques of experts' animations. Animations representing views of states of…

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 study was to assess preservice teachers' views of Nature of Science (NOS), identify aspects that were challenging for conceptual change, and explore reasons why. This study particularly focused on why and how some concepts of NOS may be more easily altered than others. Fourteen preservice science teachers enrolled in a NOS and…

This study focused on the development and validation of a three-tier multiple-choice diagnostic instrument about the ecological footprint. Each question in the three-tier test comprised by; (a) the content tier, assessing content knowledge; (b) the reason tier, assessing explanatory knowledge; and (c) the confidence tier that differentiates lack…

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…

The loss of biodiversity is one of the most urgent global environmental problems of our time. Public education and awareness building is key to successful biodiversity protection. Knowledgeable and skilled student teachers are a key component for the successful implementation of biodiversity education in schools. Yet, little empirical evidence…

A well-ordered biological complex can be formed by the random motion of its components, i.e. self-assemble. This is a concept that incorporates issues that may contradict students' everyday experiences and intuitions. In previous studies, we have shown that a tangible model of virus self-assembly, used in a group exercise, helps students to grasp…

Research has shown that students bring naive scientific conceptions to learning situations which are often incongruous with accepted scientific explanations. These preconceptions are frequently determined to be misconceptions; consequentially instructors spend time to remedy these beliefs and bring students' understanding of scientific concepts to…

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…
