Students’ Socioscientific Reasoning and Decision-making on Energy-related Issues—Development of a measurement instrument     

Mark Sakschewski  Sabina Eggert  Susanne Schneider  Susanne Bögeholz 《International Journal of Science Education》2013,35(14):2291-2313

The concept of energy is one key component of science education curricula worldwide. While it is still being taught in many science classrooms from a mainly conceptual knowledge perspective, the need to frame the concept of energy as a socioscientific issue and implement it in the context of citizenship education and education for sustainable development, is getting more and more explicit. As we will be faced with limited fossil fuels and the consequences of global climate change in the future, students have to be supported in becoming literate citizens who are able to reach informed energy-related decisions. In this article, we focus on students’ reasoning and decision-making processes about socioscientific energy-related issues. In more detail, we developed a paper-and-pencil measurement instrument to assess secondary school students’ competencies in this domain. The functioning of the measurement instrument was analysed with a sample of 850 students from grades 6, 8, 10 and 12 using item response theory. Findings show that the measurement instrument functions in terms of reliability and validity. Concerning student ability, elaborate reasoning and decision-making was characterised by the use of trade-offs and the ability to weigh arguments and to reflect on the structure of reasoning and decision-making processes. The developed measurement instrument provides a complement for existing test instruments on conceptual knowledge about the concept of energy. It aims to contribute to a change in teaching about energy, especially in physics education in the sense of education for sustainable development.  相似文献   

The Influence of Class-Size Variations on Cognitive and Affective Learning of College Freshmen     

Kenneth H. Hoover  Victor H. Baumann  Susanne M. Shafer 《Journal of Experimental Education》2013,81(3):39-43

The influence of class-size variations on cognitive and affective learning was measured by use of a 15-concept semantic differential scale and a teacher-made test. A Non-equivalent Control Group design was employed with two groups of college freshmen (N = 320). After attending a weekly lecture, 160 Ss were divided into eight permanent discussion sections (twenty Ss each) for two weekly meetings. Small-group discussions emphasized critical examination of feelings and their impact on evaluation of personal, social, and professional problems. The remaining 160 Ss (serving as a control) were divided into three conventional classes (fifty-five Ss each) for similar purposes. No significant differences were revealed from an ANOCOVA (analysis of covariance) analysis. Within the limits of this study, it appeared that large-group lectures combined with small-group discussions, were as effective as conventional classes of fifty to sixty Ss.  相似文献   

Identifying Non-Sustainable Courses of Action: A Prerequisite for Decision-Making in Education for Sustainable Development     

Helge Gresch  Susanne Bögeholz 《Research in Science Education》2013,43(2):733-754

Students are faced with a multitude of decisions as consumers and in societal debates. Because of the scarcity of resources, the destruction of ecosystems and social injustice in a globalized world, it is vital that students are able to identify non-sustainable courses of action when involved in decision-making. The application of decision-making strategies is one approach to enhancing the quality of decisions. Options that do not meet ecological, social or economic standards should be excluded using non-compensatory strategies whereas other tasks may require a complete trade-off of all the evidence, following a compensatory approach. To enhance decision-making competence, a computer-based intervention study was conducted that focused on the use of decision-making strategies. While the results of the summative evaluation are reported by Gresch et al. (International Journal of Science Education, 2011), in-depth analyses of process-related data collected during the information processing are presented in this paper to reveal insights into the mechanisms of the intervention. The quality of high school students’ (n?=?120) metadecision skills when selecting a decision-making strategy was investigated using qualitative content analyses combined with inferential statistics. The results reveal that the students offered elaborate reflections on the sustainability of options. However, the characteristics that were declared non-sustainable differed among the students because societal norms and personal values were intertwined. One implication for education for sustainable development is that students are capable of reflecting on decision-making tasks and on corresponding favorable decision-making strategies at a metadecision level. From these results, we offer suggestions for improving learning environments and constructing test instruments for decision-making competence.  相似文献   

Children’s Drawings About “Radiation”—Before and After Fukushima     

Susanne Neumann  Martin Hopf 《Research in Science Education》2013,43(4):1535-1549

Although the term “radiation” has a fixed place in everyday life as well as in the media, there is very little empirical research on students’ conceptions about this topic. In our study we wanted to find out what students associate with this term. In 2009, we asked 509 students (between grade 4 and grade 6) from seven different schools to draw pictures related to “radiation”. This method of children’s drawings was supported by short interviews (n?=?74). The motifs appearing in the drawings were analysed, and we investigated whether or not the age and the sex of the children had any influence on the choice of motifs. One major result was that the older the students were, the more likely they were to choose sources of invisible radiation (nuclear power plants, mobile phones) as their motifs. Nine months after the tragic events in Fukushima (and at the same time 2 years after the 2009 data collection), we replicated the study. This time, we received 516 drawings from the same schools as in the 2009 study (supported by 33 interviews). This replicative trend study made it possible to compare the choice of motifs and discover possible differences. The results of this analysis showed that the drawings of 2011 included significantly more motifs related to radioactivity. This difference was prevalent in the drawings regardless of sex or age differences. Direct references to the Fukushima accident could be found in both the drawings and interviews.  相似文献

The authenticity of the museum experience in the digital age: the case of the Louvre     

Yves Evrard  Anne Krebs 《Journal of Cultural Economics》2018,42(3):353-363

The technological shift of museums is extensively documented, even if research on the impact of technologies on cultural practices and social patterns at large is still lacking. As part of a research programme conducted by the Louvre and HEC Paris, the article proposes a conceptual analysis of ‘real’ (visiting the museum) and ‘virtual’ (visiting its website) experiences of museums. It contributes to the understanding of whether the two experiences are substitutes or complements using a newly created measurement scale. In addition, the article also aims at enriching the contemporary discussion on the artworks’ aura and the authenticity of the cultural experience in the digital age.  相似文献

Comparison of visual,automatic and semiautomatic methods to determine ventilatory indices in 50 to 60 years old adults     

Martin Pühringer  Susanne Ring-Dimitriou  Thomas Stöggl  Bernhard Iglseder  Bernhard Paulweber 《Journal of sports sciences》2020,38(6):692-702

ABSTRACT

The aim of this study was to compare different methods of detecting ventilatory indices (VI) and to investigate the impact of cardiorespiratory fitness (CRF) level on VI detection. Fifty females and fifty males completed a graded exercise test until volitional exhaustion with continuous gas-exchange measurement. The first and second ventilatory indices (VI-1, VI-2) were detected through different single automatic methods and through a semiautomatic method which combines visual and automatic detection methods. Additionally, the VIs were detected visually by two experts which served as the study specific gold standard. When comparing the semiautomatic method at VI-1 (intraclass correlation coefficients (ICC) 0.88 [0.81, 0.92], Bland-Altman bias ± limits of agreement (LoA) 55 ± 334 ml O₂ · min^?1) and VI-2 (ICC 0.97 [0.96, 0.98], LoA 1 ± 268 ml O₂ · min^?1) to the visually detected VI, high levels of agreements and no significant differences were found. This was not the case for any of the other automatic methods. Additionally, we couldn’t find any relevant differences regarding the CRF level.

We therefore concluded that the semiautomatic detection method should be used for VI detection, as results are more accurate than in any of the single-automatic methods.

Abbreviations: CPET: cardiopulmonary exercise test; CRF: Cardiorespiratory fitness; VO_2peak: peak oxygen uptake; VI-1: first ventilatory indices; VI-2: second ventilatory indices; LoA: Bland-Altman bias ± limits of agreement; ICC: intraclass correlation coefficient.  相似文献
