In recent years, researchers have become aware of the experiential grounding of scientific thought. Accordingly, research has shown that metaphorical mappings between experience-based source domains and abstract target domains are omnipresent in everyday and scientific language. The theory of conceptual metaphor explains these findings based on the assumption that understanding is embodied. Embodied understanding arises from recurrent bodily and social experience with our environment. As our perception is adapted to a medium-scale dimension, our embodied conceptions originate from this mesocosmic scale. With respect to this epistemological principle, we distinguish between micro-, meso- and macrocosmic phenomena. We use these insights to analyse how external representations of phenomena in the micro- and macrocosm can foster learning when they (a) address the students’ learning demand by affording a mesocosmic experience or (b) assist reflection on embodied conceptions by representing their image schematic structure. We base our considerations on empirical evidence from teaching experiments on phenomena from the microcosm (microbial growth and signal conduction in neurons) and the macrocosm (greenhouse effect and carbon cycle). We discuss how the theory of conceptual metaphor can inform the development of external representations. 相似文献

Over the last 20 years, science education studies have reported that there are very different understandings among students of science regarding the key aspects of climate change. We used the cognitive linguistic framework of experientialism to shed new light on this valuable pool of studies to identify the conceptual resources of understanding climate change. In our study, we interviewed 35 secondary school students on their understanding of the greenhouse effect and analysed the conceptions of climate scientists as drawn from textbooks and research reports. We analysed all data by metaphor analysis and qualitative content analysis to gain insight into students' and scientists' resources for understanding. In our analysis, we found that students and scientists refer to the same schemata to understand the greenhouse effect. We categorised their conceptions into three different principles the conceptions are based on: warming by more input, warming by less output, and warming by a new equilibrium. By interrelating students' and scientists' conceptions, we identified the students' learning demand: First, our students were afforded with experiences regarding the interactions of electromagnetic radiation and CO2. Second, our students reflected about the experience-based schemata they use as source domains for metaphorical understanding of the greenhouse effect. By uncovering the—mostly unconscious—deployed schemata, we gave students access to their source domains. We implemented these teaching guidelines in interventions and evaluated them in teaching experiments to develop evidence-based and theory-guided learning activities on the greenhouse effect. 相似文献

An analysis of students’ conceptions on climate change shows a great confusion on key aspects of global warming. Even after instruction students often hold conceptions that differ from scientists’ conceptions. Student’s conceptions on global warming were collected in a reanalysis of 24 studies on everyday concepts of global warming as well as in an own interview study with 35 18-year-old students from German grammar schools. Climate-scientists conceptions were analysed from textbooks and research reports in a literature study. All data were analysed by systematic metaphor analysis and qualitative content analysis. Experientialism as a theory of metaphor provided insight in the process of understanding. The analysis of conceptions by experientialism shows that students and scientists have different metaphorical conceptions of global warming – but both refer to the same schemata. These schemata in mind we categorised the conceptions of global warming. Hereby we identified different thinking patterns in students’ and scientists’ conceptions. Following the model of educational reconstruction we took the metaphorical conceptions as a starting point for the development of learning environments. By uncovering the – mostly unconsciously – employed schemata, we gave students access to their metaphorical conceptions and let them reflect on their mental models. 相似文献
