In this study, we investigated the value of a concept map marking guide as an alternative formative assessment tool for science teachers to adopt for the topic of energy. Eight high school science teachers marked students’ concept maps using an itemized holistic marking guide. Their marking was compared with the researchers’ marking and the scores of a multiple-choice diagnostic test. Statistical analysis revealed that teachers evaluated students’ concept maps consistently, but the concept map scores were only mildly correlated with the multiple-choice test scores. We explored what each assessment method revealed in terms of students’ understanding with one student’s performance as a showcase. Teachers’ views on using the marking guide of concept maps as an assessment tool were also included. We discuss the value of the concept map marking guide as a formative assessment tool for science teachers to create and modify in order to encourage students’ conceptual learning. 相似文献

The athlete’s brain exhibits significant functional adaptations that facilitate visuomotor reaction performance. However, it is currently unclear if the same neurophysiological processes that differentiate athletes from non-athletes also determine performance within a homogeneous group of athletes. This information can provide valuable help for athletes and coaches aiming to optimize existing training regimes. Therefore, this study aimed to identify the neurophysiological correlates of visuomotor reaction performance in a group of skilled athletes. In 36 skilled badminton athletes, electroencephalography (EEG) was used to investigate pattern reversal and motion onset visual-evoked potentials (VEPs) as well as visuomotor reaction time (VMRT) during a simple reaction task. Stimulus-locked and response-locked event-related potentials (ERPs) in visual and motor regions as well as the onset of muscle activation (EMG onset) were determined. Correlation and multiple regression analyses identified the neurophysiological parameters predicting EMG onset and VMRT. For pattern reversal stimuli, the P100 latency and age best predicted EMG onset (r?=?0.43; p =?.003) and VMRT (r?=?0.62; p?=?.001). In the motion onset experiment, EMG onset (r?=?0.80; p r?=?0.78; p?相似文献

Many sports require athletes to rapidly transform visual information into a targeted motor response, a process referred to as visuomotor reaction. On the behavioural level, athletes have long been established to achieve faster simple visuomotor reaction times when compared to non-athletes. However, although the superior performance in athletes has been attributed to the central nervous system, the underlying neural mechanisms remained poorly studied. More recently, a growing number of neurophysiological and neuroimaging studies systematically addressed the functional and structural modulations in the athletes’ visual and motor systems as well as their contribution to visuomotor performance. This article reviews current research on structural and functional characteristics of the athletes’ cortical visuomotor system associated with simple visuomotor reactions, sports-specific visuomotor performance and visuomotor training. The primary objective is to shed light on the neural mechanisms potentially contributing to superior visuomotor reaction performance in athletes participating in visuomotor demanding disciplines. A more comprehensive understanding of performance-determining neural functions could provide great potential for diagnostics and training to improve athletic performance. 相似文献

While the importance of a supportive context for entrepreneurship is widely acknowledged, its antecedents are rarely investigated. We apply the concept of organizational climate to higher education institutions and examine the drivers of students’ perceptions of the entrepreneurial climate in their university. Combining data from two unique datasets and using multilevel techniques, we analyze the relationship between university characteristics and such climate perceptions of 8009 students at public universities in Germany. We find university entrepreneurship measures to have a positive effect on students’ climate perceptions, which also depend on students’ background and gender. In addition, we find evidence for different peer effects, depending on students’ affinity for entrepreneurship. For the general student population, including entrepreneurship content in their normal studies seems to be required to initiate a social process of sensemaking. However, students’ perception of the entrepreneurial climate only depend to a certain degree on intentional entrepreneurship measures. In our study, general university characteristics have the strongest influence on climate perceptions. Overall, our study adds to our understanding of which parameters are important for establishing a more favorable and inspiring climate for becoming an entrepreneur at higher education institutions. 相似文献

Sustainability issues are increasingly important in engineering work all over the world. This article explores systematic differences in self-assessed competencies, interests, importance, engagement and practices of newly enrolled engineering students in Denmark in relation to environmental and non-environmental sustainability issues. The empirical base of the article is a nation-wide, web-based survey sent to all newly enrolled engineering students in Denmark commencing their education in the fall term 2010. The response rate was 46%. The survey focused on a variety of different aspects of what can be conceived as sustainability. By means of cluster analysis, three engineering student approaches to sustainability are identified and described. The article provides knowledge on the different prerequisites of engineering students in relation to the role of sustainability in engineering. This information is important input to educators trying to target new engineering students and contribute to the provision of engineers equipped to meet sustainability challenges. 相似文献

Analytical methods to assess thigh muscle balance need to provide reliable data to allow meaningful interpretation. However, reproducibility of the dynamic control ratio at the equilibrium point has not been evaluated yet. Therefore, the aim of this study was to compare relative and absolute reliability indices of its angle and moment values with conventional and functional hamstring–quadriceps ratios. Furthermore, effects of familiarisation and angular velocity on reproducibility were analysed. A number of 33 male volunteers participated in 3 identical test sessions. Peak moments (PMs) were determined unilaterally during maximum concentric and eccentric knee flexion (prone) and extension (supine position) at 0.53, 1.57 and 2.62 rad · s–1. A repeated measure, ANOVA, confirmed systematic bias. Intra-class correlation coefficients and standard errors of measurement indicated relative and absolute reliability. Correlation coefficients were averaged over respective factors and tested for significant differences. All balance scores showed comparable low-to-moderate relative (<0.8–0.9) and good absolute reliability (<10%). Relative reproducibility of dynamic control equilibrium parameters augmented with increasing angular velocity, but not with familiarisation. At 2.62 rad · s–1, high (moment: 0.906) to moderate (angle: 0.833) relative reliability scores with accordingly high absolute indices (4.9% and 6.4%) became apparent. Thus, the dynamic control equilibrium is an equivalent method for the reliable assessment of thigh muscle balance. 相似文献

The present article reports on a research project investigating the experiences of male primary teachers in Queensland, Australia. While its findings cannot be presented as indicative of all male teachers in all contexts, it does, however, send a warning to policy‐makers that the employment of more male teachers may not be in the best interests of gender justice unless such strategies designed to attract more male teachers are informed by sophisticated understandings of gender and social power. Utilising a (pro) feminist post‐structuralist theoretical perspective, it is demonstrated how some male teachers contribute to the maintenance of segregated work roles, which is of central importance to the continuance of gender power differentials in a patriarchal society. The research method focused on social relationships and involved a series of semi‐structured/life history interviews with 11 male teachers, six female teachers, two male principals and two female principals. An important implication from this research is that the employment of male teachers must be accompanied by an awareness of how teacher practice impacts upon the socialisation of students and how such practice reinforces or contributes to change in the broader gender system. 相似文献

This article is a general introduction into the special issue of Archival Science on “archiving research data”. It summarizes
the different contributions and gives an overview of the main issues in this special field of archiving. One of the leading
questions is how and why research data archives differ from public record offices. In the past, the developments in these
two worlds have been rather separate. There are however signs that they are converging in the digital world. In particular,
this can be seen in the areas of metadata and Internet dissemination as these are strongly influenced by the rapid changes
in information technology. These changes have also led to important new developments in the infrastructure of research data
to which special attention is paid. New concepts such as collaboratories, data curation, Open Access and the Open Archives
Initiative are discussed.
