The aims of this study were to analyse recreational sea kayaking and touring incidents in Norway with a specific focus on wind conditions and to elaborate on practical implications for the prevention of future incidents. We included 49 incidents reported by the media between 2000 and 2014. Incidents occurred in various wind conditions, but most incidents (60%) occurred in moderate to strong breezes (9–14 m/s). Wind strength and direction were generally forecast accurately and conditions were mainly stable throughout the day of the incident. Thus, sea kayaking and touring incidents in Norway seem to happen in various wind conditions; however, paddlers should have been well informed and aware of the hazards they were facing. Future incidents could be prevented by increasing sea kayakers’ situation awareness through discussion of experts’ decision-making processes and the arrangement of situated learning experiences in realistic settings.  相似文献

The aim of the present study was to collect in a systematic way empirical data about the (lack of) activation of real-world knowledge during elementary school pupils' understanding and solution of school arithmetic word problems. Ten pairs of word problems were collectively administered to 75 fifth-graders during a typical mathematics lesson. While the first item of each pair could be modeled and solved in a straightforward and unproblematic way by one or two simple arithmetic operations with the given numbers, the second problem could not be modeled and solved in such a way, at least if one seriously takes into account the realities of the context called up by the problem statement. An analysis of the pupils' reactions to these problematic word problems shows an alarmingly small number of realistic responses or additional comments based on realistic considerations.  相似文献

A possible path towards preserving and remediating driving skills while aging is driver training. Previous studies have yielded mixed results with respect to various types of interventions, such as classroom-based training, on-road driving classes and functional abilities training. The present study-incorporated training features found to be effective in previous older driver training studies, into both a computer-based and driving simulator-based intervention. The purpose of the present study was to investigate the effect of both training formats on general driving ability and specific aspects of driving in older drivers at risk of reduced driving abilities. Additionally, the effect of training on perceived task demand was studied, and learning capacity was considered as an influencing factor on training effectiveness. A total of 31 older drivers were randomly assigned to three groups: driving simulator-based training, computer-based training, and an active control group. The participants completed a cognitive assessment including evaluation of learning capacity and a self-assessment of task demand in various traffic situations. Additionally, participants took a driving simulator assessment. Knowledge of road signs, general driving and specific aspects of driving (i.e., average speed, response time to hazards) improved with training, although improvement was found to be evenly strong in all groups. Learning capacity did not influence training effectiveness, and no difference was found in perceived task demand before and after training. The proposed methodology to evaluate training effectiveness, focusing both on clinically relevant and detailed transfer effects can serve as an example for further studies in the field of driver training.  相似文献

Understanding how children think about the needs of animals may aid bridging from how they care about individual animals to caring about the environment more generally. This study explored changes with age in children's conceptions of animals' needs, including how such conceptions may extend beyond the individual animal to larger systems and conservation. During attendance at a North American zoo, 171 children between the ages of 4 and 14 years were interviewed and did drawings in response to questions about the needs of a favorite animal. The results reported here focus on developmental patterns. Animals' basic physiological needs were grasped at an early age. Understanding ecological and conservation needs showed the strongest developmental trends across the full age range, with some children showing early proficiency in ecological, but not conservation, concepts. Conservation and ecological thinking appeared to follow different trajectories, especially through middle childhood, when other dimensions than knowledge may cause increases in conservation conceptions. Educational implications include building on interest in individual animals; not underestimating even young children's ability to assemble ecological facts around an animal; emphasizing concrete ecological connections; and highlighting animals that children experience in their own lives. Considering the needs of animals offers a developmentally pre‐potent way to increase how children know and value multiple levels of biological organization.  相似文献

The fields of science education and science communication are said to have developed as disparate fields of research and practice, operating based on somewhat different logics and premises about their audiences. As the two fields share many of the same goals, arguments have been made for a rapprochement between the two. Drawing inspiration from a historical debate between the scholars John Dewey and Walter Lippmann, the present article is a case-oriented theoretical contribution applying models from science education and science communication in relation to a current socio-scientific issue (SSI), the COVID-19 pandemic. The main question of interest is how selected didactic (didaktik) models from science education and science communication can contribute to shed light on the present situation of an ongoing pandemic specifically and socio-scientific issues in general. Three models are synthesised to give a new composite model that may help communicators and educators understand, discuss, and analyse complex socio-scientific issues. The model is subsequently applied on the apparently contradictory issue of Norwegian and Swedish governments’ very different responses to the pandemic, despite grounding their decisions on largely the same scientific evidence and advice. Contrast is made by comparison with another SSI, anthropogenic global warming (AGW). It is argued that the exchange and combination of didactic models from the two fields may open new spaces for cross-pollination and cross-fertilisation to the mutual benefit of both science education and science communication.

Students participated in a study (n=98) investigating the effectiveness of three types of annotations on three learning outcome measures. The annotations were designed to support the cognitive processes in the comprehension of scientific texts, with a function to aid either the process of selecting relevant information, organizing the information in memory, or integrating information with prior knowledge. Learning outcomes were measured by assessing student recall of facts, comprehension of the text, and mental model construction. Results show that different types of annotations facilitate different learning outcomes. In addition, we found that, compared to having only one type of annotation available, multiple types of annotations resulted in a higher cognitive load that resulted in lower performance, especially in tests of higher-level processing. This effect was stronger for low-verbal-ability learners, who showed lower peformance in treatments with multiple types of annotations than high-verbal-ability learners.  相似文献

Inclusion is a term and process that is culturally, politically, medically, philosophically, and historically relative in its interpretations in the education of the deaf. The present study is a comparative analysis of two substantially different education systems for deaf students, those of Norway and Australia. The study objective was to elucidate the sources of some of these differences and to examine the interpretations and applications of inclusion that are inherent in the two countries' policies and practices, and in recent research evaluations. Significant differences exist in the national contexts and in the manner in which inclusion is understood and applied in Norway and Australia; the study reports on recent research examinations of inclusion in the two countries and finds that the transitions from policy to practice seem questionable.  相似文献

Student perceptions are a pivotal point of measurement for understanding why classroom learning environments are effective. Yet there is some evidence that student perceptions cannot be reliably aggregated at the classroom level and, instead, could represent idiosyncratic experiences of students. The present study examines whether heterogeneity in student perceptions of the classroom climate has implications for student achievement. We use data from 1428 seventh grade students in 75 mathematics classrooms from the Michigan Study of Adolescent and Life Transitions. Three dimensions of student perceptions of the classroom were measured: emotional support, autonomy support and performance focus. To obtain a measure of heterogeneity, we first reduced the data using latent profile analysis to describe profiles of students’ perceptions of the classroom. Next, we quantified the heterogeneity of student perceptions within classrooms using Simpson’s D. Classroom-level heterogeneity (Simpson’s D) of students’ perceptions was negatively associated with students’ mathematics achievement, even after controlling for individual- and classroom-level previous achievement, student’s prior perceptions and other variables. Findings suggest that measures of heterogeneity in student perceptions might be important for understanding classroom- and teacher-level effects on student outcomes.  相似文献
