Plant nutrition is a complex subject at any educational level therefore, identification of student's ideas regarding this scientific concept is important in order to define the best instructional learning method. In this study, we conduct a cross-age comparison of the conceptual understanding of compulsory students and prospective elementary…

This study examines the drawings that 178 young children carried out on two different occasions separated by a period of one year to explain their understanding of the plant world. The pictorial content of the drawings was analysed in accordance to the categories that previous research has proved to be useful when it comes to gaining an insight…

Children's conceptions of plants as living things are thoroughly analysed during the last decades. Additionally, many researchers showed interest in 'Plant Blindness', the people's tendency to ignore plants and underestimate them comparing to animals. Aim of this research is to validate plant blindness' intensity among Greek primary school…

Trees are important to the environment owing to their ecological services. However, many aspects of their form and function are poorly understood by the public. From their earliest years, children have an elementary knowledge about plants which they gain from their everyday observations, their parents and other people and from their kindergarten…

This study examines the drawings that elementary grade school children make on the subject of plant life. More specifically, the pictorial elements drawn by children are analysed together with their colour choices and the size of coloured surfaces. Furthermore, the results are put into perspective with the age of the children in the sample. The…

This practical paper describes a novel fluorescence imaging experiment to study the three processes of photochemistry, fluorescence and thermal energy dissipation, which compete during the dissipation of excitation energy in photosynthesis. The technique represents a non-invasive tool for revealing and understanding the spatial heterogeneity in…

The development of a diachronic conception of biology has rarely been explored during childhood, except by Maurice-Naville and Montangero (1992). The aim of the present study was to further explore this issue. In the course of an interview, 163 children aged between 6 and 11 expressed their diachronic conceptions of the growth and death of several…

Because the National Science Education Standards (1996) outline specific things K-8 students should know about plants, and previous data indicated that elementary students had difficulty understanding some major ideas about plants and plant growth, the authors of this article thought it appropriate to initiate an investigation to determine the…
