Why Use Multiple Representations in the Mathematics Classroom? Views of English and German Preservice Teachers     

Anika Dreher  Sebastian Kuntze  Stephen Lerman 《International Journal of Science and Mathematics Education》2016,14(2):363-382

Dealing with multiple representations and their connections plays a key role for learners to build up conceptual knowledge in the mathematics classroom. Hence, professional knowledge and views of mathematics teachers regarding the use of multiple representations certainly merit attention. In particular, investigating such views of preservice teachers affords identifying corresponding needs for teacher education. However, specific empirical research is scarce. Taking into account the possible role of culture, this study consequently focuses on views about using multiple representations held by more than 100 English and more than 200 German preservice teachers. The results indicate that there are culture-dependent aspects of preservice teachers’ views, but also that there are common needs for professional development.  相似文献   

From childhood nature experiences to adult pro-environmental behaviors: An explanatory model of sustainable food consumption

Abstract

In two studies, the role of nature experiences and social norms during childhood is explored next to adulthood biospheric values, connectedness to nature, environmental identity, and objective knowledge in relation to pro-environmental behaviors. Study 1 (N?=?185) tested the hypothesized model in the realm of general pro-environmental behaviors and sustainable fruit consumption on a sample of students. Study 2 (N?=?155) tested the model in the realm of sustainable seafood consumer choice on a general population sample. Path analyses show consistent results across samples. Results show that childhood nature experiences and exposure to pro-environmental social norms during childhood are related to adulthood development of connectedness with nature and biospheric values; these, in turn, help in shaping adulthood environmental self-identity ultimately influencing the enactment of sustainable food choices during adulthood. These findings point toward the relevance of childhood experiences for pro-environmental behaviors as compared to the provision of information. The role of objective knowledge across samples is inconsistent, thus requiring future investigations.  相似文献

The Development of Clustering in Episodic Memory: A Cognitive-Modeling Approach     

Sebastian S. Horn  Ute J. Bayen  Martha Michalkiewicz 《Child development》2021,92(1):239-257

Younger children’s free recall from episodic memory is typically less organized than recall by older children. To investigate if and how repeated learning opportunities help children use organizational strategies that improve recall, the authors analyzed category clustering across four study-test cycles. Seven-year-olds, 10-year-olds, and young adults (N = 150) studied categorically related words for a free-recall task. The cognitive processes underlying recall and clustering were measured with a multinomial model. The modeling revealed that developmental differences emerged particularly in the rate of learning to encode words as categorical clusters. The learning curves showed a common pattern across age groups, indicating developmental invariance. Memory for individual items also contributed to developmental differences and was the only factor driving 7-year-olds’ moderate improvements in recall.  相似文献   

Molecular mechanism of heterogeneous catalysis     

R. S. Swathi  K. L. Sebastian 《Resonance》2008,13(6):548-560

Gerhard Ertl, the German physical chemist, was awarded the Nobel Prize in chemistry for the year 2007, for his contributions in the area of surface science. His painstaking work led to a microscopic understanding of heterogeneous catalysis in industrially important chemical reactions. These include the Haber-Bosch process for the production of ammonia, and the catalytic oxidation of carbon monoxide. (left) R S Swathi is a Senior Research Fellow at the Department of Inorganic and Physical Chemistry, working with Prof. K L Sebastian. Her research interests include theoretical study of resonance energy transfer involving various donor-acceptor systems.

Reducing the Bias: How Perspective Taking Affects First- and Third-Person Perceptions of Media Influence     

Philipp Müller  Sebastian Scherr 《Communication Research Reports》2017,34(2):134-142

Third- and first-person perceptions (TPPs/FPPs) are considered to be biased judgments of media influence on self and others. Research suggests that perspective taking, i.e., thinking from another person’s position, decreases perceptual gaps between self and others via assimilation. In a two-factorial experiment (n = 431), we test whether this effect of perspective taking (Factor 1) holds true for the presumed influence of desirable and undesirable messages (Factor 2). Results indicate that perspective taking significantly reduces TPPs in the case of an undesirable message but not FPPs that are provoked by the desirable message. The observable effect traces back to a change in presumed message influence on the self. Presumed influence on others was independent of both factors, desirability of message influence and perspective taking. These findings are discussed in the light of cognitive and motivational explanations for FPPs/TPPs.  相似文献   

The biomechanical structure of swim start performance     

Sebastian Fischer  Armin Kibele 《Sports biomechanics / International Society of Biomechanics in Sports》2016,15(4):397-408

The aim of this study was to analyse the significance of various biomechanical parameters in swim start performance for the grab and track start techniques. To do so, structural equation models were analysed, incorporating measurements for the take-off phase, flight phase and entry phase. Forty-six elite German swimmers (18 female and 28 male; age: 20.1 ± 4.2 yrs; PB (100 m Freestyle): 53.6 ± 2.9 s) participated in the study. Their swim start performance was examined within a 25-m sprint test. Structural equation modelling was conducted in separate models for the block time, flight time and water time and in a combined model for swim start time. Our main finding was that swim start time is predominantly related to water time and determined to a lesser extent by block time and flight time. We conclude that more emphasis should be given to the water immersion behaviour and the gliding phase when analysing swim start performance. Furthermore, significant differences were found between the grab start and track techniques as regards the biomechanical parameters representing the take-off phase and water phase.  相似文献
