Education systems increasingly emphasize the importance of scientific reasoning skills such as generating hypotheses and evaluating evidence. Despite this importance, we do not know which tests of scientific reasoning exist, which skills they emphasize, how they conceptualize scientific reasoning, and how well they are evaluated. Therefore, this article reviews 38 scientific reasoning tests. They used to primarily consist of multiple-choice questions, but since then have become more diverse, even including tests that automatically analyse virtual experiments. Furthermore, this review revealed that the tests focus on the skills of generating hypotheses, generating evidence, evaluating evidence, and drawing conclusions. Additionally, conceptualizations of scientific reasoning have moved towards a domain-specific set of different but coordinated skills over the years. Finally, concluding from gaps in test evaluation, a future focus should be on testing theoretical assumptions, comparing different scientific reasoning tests, and how relevant test results are in predicting criterion variables like academic performance. 相似文献

Zadie Smith's most recent novel, On Beauty (2005), declares its connection to E. M. Forster's Howards End (1910) with its first line, while the novel's title comes from Elaine Scarry's On Beauty and Being Just (1999). At least as important for understanding Smith's central vision are the novel's allusions to Zora Neale Hurston's Their Eyes Were Watching God (1937) and Tell My Horse: Voodoo and Life in Haiti and Jamaica (1938). 相似文献

One likely mechanism in learning new skills is change in synchronous connections between distributed neural networks, which can be measured by coherence analysis of electroencephalographic patterns. This study examined coherence changes during the learning of two tasks, a word association task and a figure association task. Although learning curves were similar for both tasks, distinct patterns of coherence change were observed. Coherence tended to increase as learning progressed in the figure association task. In contrast, coherence tended to decrease in the word association task, especially within hemisphere. Word learning was coupled with negative intrahemispheric and positive interhemispheric performance–coherence relations in the gamma frequency. Unique to the figure learning task was an increase in the number of positive coherence–performance relations in both delta and theta frequencies across blocks. Results are discussed in light of ongoing efforts to identify the mechanisms that coordinate distributed brain activities during the process of learning. Further research is needed to define patterns of coherence change for different tasks, goals, and brain regions. 相似文献

Given the mixed evidence for the impact of various publicly funded initiatives that aim to foster entrepreneurial activity, this paper empirically examines the efficacy of publicly funded business advisory services in relation to entrepreneurial outcomes. Based on a sample of 228 early-stage firms, of which 101 used business advisory services focused on helping companies secure 1st rounds of financing and start generating revenues, we examine the firm-level impact such services can have on sales growth, innovation, finance and alliances. We find services are positively associated with firms’ sales growth, patents, finance and alliances. We assess statistical and economic significance, and assess robustness to controls for the non-randomness of the firm's using business advisory service program, as well as endogeneity of advisors’ hours spent with firms. Other robustness checks are also included. We find significant robustness of hours spent on sales and finance, but sensitivity of the effect of hours on patents and alliances after controlling for endogeneity. 相似文献

Flexural and torsional rigidity are important properties of skis. However, the flexural and torsional rigidity that lead to optimal performance remain to be established. In the present study, four pairs of slalom skis that differed in flexural and torsional rigidity were tested by advanced and expert skiers. Using a 10-item questionnaire, different aspects of the skis' performance were rated on a 9-point scale. For each pair of skis, physical measurements were compared with the ratings of the two groups of skiers. Correlations (Spearman) were then determined between (i) different mechanical properties of the skis (static and dynamic), (ii) subjective assessments of the participants, and (iii) properties of the skis and the participants' assessments. The latter showed that expert skiers rate the aspects of the skis more accurately than advanced skiers. Most importantly, expert skiers are particularly sensitive to torsion of the skis. These results suggest that such highly rated elements should be addressed in future ski designs. 相似文献
