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   

Employers’ support for adult higher education students in liberal post-socialist contexts     

Ellu Saar  Rein Vöörmann  Ailen Lang 《International Journal of Lifelong Education》2013,32(5):587-606

In most European countries, the proportion of adult students among both full-time and part-time workers has increased significantly over recent decades. Undertaking paid work is also increasingly common among traditional students. The opportunities to work while studying depend largely on the role of employers in promoting learning. However, both theoretical frameworks and empirical studies typically focus on the behaviour of firms in providing training. The support of employers for formal adult education has remained a marginal topic. The aim of this article is to analyse the contributions of employers to the acquisition of higher education from the perspective of the adult learners; we investigated how employers support their staff in higher education studies. We also tried to identify which kinds of learners have a better chance of receiving various benefits. We used two different data-sets: quantitative data from a study of adult students in higher education and qualitative data from interviews with managers of small- and medium-sized enterprises and at least one employed participant in formal adult education, collected in the framework of the international research project Towards a Lifelong Learning Society in Europe: The Contribution of the Education System supported by the EU Sixth Framework Programme.  相似文献

Temporal Contingency as an Independent Component of Parenting Behavior   总被引：3，自引：0，他引：3  

Heidi Keller  Arnold Lohaus  Susanne Völker  Martina Cappenberg  & Athanasios Chasiotis 《Child development》1999,70(2):474-485

Several theoretical conceptions emphasize the importance of prompt responses to infant's signals in providing them with early causal experiences. The present paper examines if a maternal tendency toward prompt responses can be identified by distributional analyses of maternal response latencies and if this response tendency can be shown for different communicative channels (in verbal/vocal, nonverbal, intermodal communication). In addition, the paper focuses on the relation between the temporal contingency of maternal behavior and measures of maternal interactional quality. Interactional sequences of 54 mother and 3-month-old infant dyads were analyzed using microanalytical assessment techniques and ratings of interactional quality. Distributional analyses of maternal expressions during face-to-face encounters revealed that promptness of responses toward infant signals with a short latency is a typical response tendency in maternal behavior. There are, however, individual differences between mothers, indicating that this response tendency is expressed in different communicative channels by individual mothers. This is shown by low correlations between the contingency indices of different communicative channels. The relation between contingency and rated indicators of interactional quality turned out to be rather small, indicating that maternal contingency may be conceptualized to contribute an independent factor to the quality of maternal interactional behavior.  相似文献   

Reducing the prior-knowledge achievement gap by using technology-assisted guided learning in an undergraduate chemistry course     

Anna J. Lou  Susanne M. Jaeggi 《科学教学研究杂志》2020,57(3):368-392

There have been many practical obstacles for teachers to implement evidence-based educational technology, especially in STEM classrooms. By implementing learning principles related to Cognitive Load Theory, we developed an innovative Technology-Assisted Guided Learning (TAGL) approach and its web-based instructional tool, combining expertise from educational research and best teaching practices to enhance guided student-centered learning in chemistry. A total of 185 community college students were randomly assigned to learn stoichiometry through either TAGL or one of two active control interventions, traditional direct instruction and Khan Academy, a widely used web learning platform. We found that the TAGL group significantly outperformed both active control groups immediately after instruction, and furthermore, despite the fact that all groups received additional instruction in stoichiometry, the beneficial effects of TAGL compared to the control groups were maintained a month later. Notably, TAGL was able to eliminate the achievement gap between students with low prior knowledge and students with high prior knowledge. Furthermore, prior-knowledge activation was found to be especially beneficial for students with low prior knowledge. Our work contributes to existing research in learning theories and provides new insight toward the development of more effective and adaptive instructional designs. By translating research into practice, this study demonstrates the great potential of using innovative computer-based technology to improve student learning for all.  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
