This article focuses on the need for increased attention to content issues and working methods for science teaching in Early Childhood Education (ECE). Science education research emphasises the importance of not only focusing on specific phenomena, but also on the Nature of Science (NOS). NOS teaching deals with questions about what science is,…

It has long been argued that nature of science (NOS) is an important part of science teaching. In the literature, many different approaches to NOS have been suggested. This article focuses on a storytelling approach, and builds on data from audio recordings from three middle-school (school year 6) classrooms. The three science classes are run by…

Traditional school science has been described as focused on indisputable facts where scientific processes and factors affecting these processes become obscured or left undiscussed. In this article, we report on teachers' perspectives on the teaching of sociocultural and subjective aspects of the nature of science (NOS) as a way to accomplish a…

Research shows that students have problems understanding thermodynamic concepts and that a gap exists at the tertiary level related to more specific chemistry concepts such as enthalpy. Therefore, the aim of this study is to construct undergraduate students' conceptions of enthalpy, its change and related concepts. Three explorative small-scale…

This study aimed to explore lower secondary teachers' negotiation of the meaning of laboratory work in a professional development program. A total of 15 in-service teachers participated in the program. In the program, tensions between key ideas concerning traditional way of addressing laboratory work -- with emphasis on subject content and skills…

A roller coaster ride comes to an end. Magnets on the train induce eddy currents in the braking fins, giving a smooth rise in braking force as the remaining kinetic energy is absorbed by the brakes and converted to thermal energy. In this paper an IR camera was used to monitor the temperature of the first braking fin, before, during and after the…

Many modern cell phones have built-in sensors that may be used as a resource for physics education. Amusement rides offer examples of many different types of motion, where the acceleration leads to forces experienced throughout the body. A comoving 3D-accelerometer gives an electronic measurement of the varying forces acting on the rider, but a…

During a roller coaster ride, the body experiences acceleration in three dimensions. An accelerometer can measure and provide a graph of the forces on the body during different parts of a ride. To couple the experience of the body to pictures of the ride and an analysis of data can contribute to a deeper understanding of Newton's laws. This…

In this paper, we describe two central epistemological norms related to the importance of making investigations and to scientific language and its logic. These norms have been identified in empirical material consisting of 200 video-recorded lessons in three different science classes. With regard to the learning of science and socialization, we…

The conversation between myself and Professor Lederman took place in Malmö, Sweden on August 25, 2007. The purpose of the conversation was to elaborate on the past, present and future of nature of science research and also to provide insights for beginning researchers. In this text I am providing the questions about which we talked and my…
