Abstract

The present study aimed to investigate the mental representations of 5–6-year-old children about electric current. The research was qualitative in nature and was conducted using semi-directed individual interviews along three directions: An initial approach to children's mental representations regarding the presence of electric current in familiar environments, the place of its generation as well as the transport of it to houses. The findings showed that children tend to deal with the topic intuitively, mainly relying on their individual experiences. In addition, the findings revealed that despite the difficulties they face, young children have already formed some naïve mental representations about electric current. These results are part of a broader field of findings in the area of Early Childhood Education that studies the development of young children's thinking about natural phenomena and physical science concepts.

Abstract

In this paper, we present the findings of a research which has two objectives: firstly, it recorded 12-13 years old (7th grade) students’ mental representation regarding the vision of non-luminous objects, and, secondly, it emphasized on the relative cognitive fields. The research was done through interviews of 107 urban area students in Greece. The students were asked to explain how objects become visible, stressing the following themes: The manner in which our eyes help us see the objects, whether natural or artificial light helps us see the objects and in what way, and if the objects emit light. The data analysis led to the recording of the students' basic mental representation on the one hand, while on the other hand emphasized the reemission or reflection of light by the luminous objects as a basic mental representation.From the research results, it can be concluded that through a teaching intervention based on mental representation we can foster and enhance scientific thinking and learning about light and vision.

Abstract

In this paper, we present the findings of research on mental representations of thermal conduction on the metal of children aged 5-6 years. The research was carried out using interviews of 87 urban area kindergarten students in Greece. The children were asked for predictions and macroscopic descriptions of phenomena illustrated in 3 different tasks during which simple thermal conduction experiments were performed with both daily and non-daily materials. The research results clearly show the vast majority of children express mental representations which are far from the scientific models used in education. Moreover, many children can make predictions on heat conduction without being able to analyze their way of thinking. Finally, differences were found in heat conduction on familiar and non-familiar materials used by children. Findings of the current research study are likely to equip teachers with the appropriate basic tools for designing their teaching interventions in the lessons of heat and thermal conduction for children aged 5-6 years.
