Atmospheric jets and vortices on Jupiter persist for decades in the presence of vigorous turbulence which might be expected to destroy organized flows. The penetration depth of the jets into the planet has been a major question, and new data from the NASA Galileo entry probe suggest that they are not shallow atmospheric phenomena. Numerical simulations and Galileo orbiter data promise further progress in the near future. 相似文献

Several scholars contend that learning with computer games and simulations results in students thinking more like professionals. Bearing this goal in mind, we investigated how a group of pharmacy students learnt with an in‐house developed computer simulation, SimPharm. Adopting situated cognition as our theoretical lens, we conducted a case study involving 20 undergraduate students to tease out how they made meaning of a clinical case differently in two different contexts: a typical paper‐based workshop and one enabled by SimPharm. The data collected included audio recordings of classroom discourse, focus group interviews and class observations. The findings identified differences in four areas: framing of the problem; problem‐solving steps and tools used; sources and meaning of feedback; and conceptualisation of the patient. These four areas can serve as axes along which future evaluations of educational simulations can be carried out based on their affordances. 相似文献

Student perceptions of quality feedback in teacher education 总被引:1,自引:1,他引:0
Peter Ferguson 《Assessment & Evaluation in Higher Education》2011,36(1):51-62
Many reports have identified a perceived lack of quality in regard to assessment feedback in higher education contexts. One research study in 2007 on undergraduate university students found that less than half of the students (46%) collected their formative feedback, suggesting that from their perspective feedback clearly was not fulfilling the role it should. This is a study of 465 graduate students and 101 undergraduate students studying teacher education at a major Australian university. The study investigated what students perceived to be effective, quality feedback based upon their extensive higher education experiences. Students identified preferences in regard to form, detail and timing of assessment feedback. The data were collected by means of pen and paper survey and identified which strategies the students perceived to be the most effective, particularly within the context of large cohort teaching and written assessment formats. Findings agreed with research elsewhere regarding problems with assessment feedback quality and quantity, but students also provided clear indications of how realistic improvements could be made in terms of assessment feedback processes and strategies. 相似文献

There is much disagreement in the literature over the extent to which graduates are mismatched in the labour market and the reasons for this. In this paper we utilise the Flexible Professional in the Knowledge Society (REFLEX) data set to cast light on these issues, based on data for UK graduates. We find substantial pay penalties for overeducation for both sexes and for overskilling in the case of men only. When both education and skill mismatch variables are included together in the model only overskilling reduces job satisfaction consistently for both sexes. Using job attributes data it appears that the lower wages of the overqualified may in part simply represent a compensating wage differential for positive job attributes, while for men at least there are real costs to being overskilled. 相似文献

Information‐rich environments are created to promote data use in schools for the purpose of self‐evaluation and quality assurance. However, providing feedback does not guarantee that schools will actually put it to use. One of the main stumbling blocks relates to the interpretation and diagnosis of the information. This study examines the relationship between data literacy competences, support given in interpreting the information, actual use of the feedback and potential school improvement effect. A randomised field experiment with 188 school principals from primary education was set up and a post‐test was used to investigate the effects of a support initiative. The results revealed that a minority of schools invested significantly in the interpretation and diagnosis of the school performance feedback (SPF), despite the fact that most of the respondents showed an interest in the SPF report. In addition, data competence support and the subsequent use of feedback were found to be limited. 相似文献
