Relational reasoning is the foundational cognitive ability to discern meaningful patterns within an informational stream, but its reliable and valid measurement remains problematic. In this investigation, the measurement of relational reasoning unfolded in three stages. Stage 1 entailed the establishment of a research-based conceptualization of the construct and the development of a corresponding Test of Relational Reasoning (TORR). Stage 2 focused on the reliability and validity of data from the TORR. Analyses showed the data from the TORR to be reliable indicators of students' ability to reason relationally, and TORR performance predicted students' performance on SAT verbal and math problems. Stage 3 examined the underlying structure of the construct through Confirmatory Factor Analysis (CFA). Of the three CFA models tested, models with dedicated factors for analogical, anomalous, antinomous, and antithetical reasoning were deemed the best fit for the data. 相似文献
The independent effects of facial and vocal emotional signals and of positive and negative signals on infant behavior were investigated in a novel toy social referencing paradigm. 90 12-month-old infants and their mothers were assigned to an expression condition (neutral, happy, or fear) nested within a modality condition (face-only or voice-only). Each infant participated in 3 trials: a baseline trial, an expression trial, and a final positive trial. We found that fearful vocal emotional signals, when presented without facial signals, were sufficient to elicit appropriate behavior regulation. Infants in the fear-voice condition looked at their mothers longer, showed less toy proximity, and tended to show more negative affect than infants in the neutral-voice condition. Happy vocal signals did not elicit differential responding. The infants' sex was a factor in the few effects that were found for infants' responses to facial emotional signals. 相似文献
This study focuses on problems in pupils’ reasoning when they situate historical phenomena in time. The context is the Dutch curriculum with 10 eras and characteristic features, which was implemented to support pupils in orientating themselves in time. Twenty-two pupils aged 6–12 conducted assignments in which they had to place historical phenomena in time. Next to problems that were described in previous studies, problems were identified that related to the names and icons of the 10 eras, which sometimes helped, but also hindered pupils in their reasoning. Awareness of these problems is helpful for teachers, teacher trainers and educational policymakers. 相似文献
Tasks which invite students to identify with historical actors and describe their perspectives are a common phenomenon in history education. The aim of this study is to explore the differences in students’ answers when completing a writing task in first person (‘imagine you are in the past’) or in third person (‘imagine someone in the past’), or a task in which such imagination is not explicitly asked. Furthermore we investigated the effects of the type of task on topic knowledge and situational interest. Students in Dutch secondary education (N = 254) participated by completing a task on the Dutch Iconoclasm. Our analysis of student answers focused on aspects of historical empathy: historical contextualization, affective elements and perspective taking.
Results were that all students gained some knowledge from the task, regardless of the type of task they completed. Students’ situational interest also did not differ between the three tasks. However, students’ written work showed that the first- and third-person writing tasks stimulated students to imagine concrete details of the past and emotions of historical actors. Students who were not explicitly asked to imagine themselves or someone in the past included more perspectives into their writings. Students who completed the task in first person tended to show more presentism and moral judgements of the past than students who completed a task in third person. 相似文献
This study examined relations among children's individual experiences, global classroom quality, and school readiness. Preschool children from low-income backgrounds (N = 138; M = 62.16 months; SD = 3.93; range = 55?70) were observed in their early care and education settings, and their language and cognitive skills were assessed. Research Findings: Individual children in classrooms with small group sizes had higher quality individual experiences even though global classroom quality was not necessarily better. Higher levels of global classroom quality did not ensure that every child in the classroom was engaged fully in available interactions and activities. Children with disabilities were generally enrolled in classrooms with higher global quality and had higher quality individual experiences than those without disabilities; however, children without disabilities enrolled in these inclusive classrooms did not necessarily have a higher level of individual experiences than those in non-inclusive classrooms. Children's individual experiences and the global quality of their classrooms were associated with their social skills. Only the quality of children's individual experiences was found to be related to the quality of their relationships with teachers. Practice or Policy: Ratings of children's individual experiences provide information beyond that provided by global ratings of classroom quality and have potential for informing efforts to individualize educational programs. 相似文献
The expert-performance approach guided the collection of survey data on the developmental history of elite professional ballet dancers from three different countries/cultures (USA, Mexico, and Russia). The level of ballet expertise attained by age 18 was found to be uniquely predicted by only two factors, namely the total number of accumulated hours of dance practice through age 17 and the age of first having the “idea of becoming a professional dancer.” Older starting ages were associated with a more rapid increase of weekly training, so starting ages were not correlated with amount of practice accumulated at age 17 or attained ballet performance by age 18. Different detailed developmental paths leading to elite ballet performance are described and their theoretical implications discussed. 相似文献
Women who test positive for a BRCA genetic mutation, but who have not been diagnosed, or 'previvors,' experience intense, chronological risk-related uncertainty. Women’s risk management medical decisions can be a way to manage their uncertainty, but little is known about how uncertainty informs their decision or how uncertainty is impacted by these medical decisions. Using an uncertainty management theoretical lens, we interviewed 46 previvors about their decision-making process. A thematic analysis revealed two uncertainty management (i.e., risk-reducing) decision-making pathways (preventive surgery and increased surveillance) with each pathway encompassing a three-part process of 1) uncertainty appraisal, 2) medical decision (i.e., uncertainty management strategy), and 3) outcomes. The findings advance theoretical thinking about uncertainty and risk management as an ongoing, distressful chronic experience, and highlight the importance of life-span phenomena in women’s decision-making process. Based on the findings, we constructed a translational tool to aid genetic counselors and previvors facing these medical decisions. 相似文献
Integrated library systems (ILSs) have been fundamental to library workflow in both technical services and public services for decades. However, many of the proprietary ILSs currently on the market do not provide law libraries with the flexibility and adaptability necessary to keep pace with advances in technology. Some law libraries are considering abandoning proprietary ILSs and implementing one of the nascent open source ILSs that have sprung up in the last few years. As the lines blur between hardware and software, many organizations are trading in-house information technology infrastructure and personnel for full-service cloud hosting. This article examines these trends for those contemplating a move to an open source ILS and/or cloud computing. 相似文献
AbstractThe aims of the this prospective study were to analyse physical activity (PA) engagement during the first and second trimesters, considering the different guidelines published on PA, to document the individual characteristics associated with the accomplishment of these guidelines and to examine pregnant women’s perceived barriers to leisure PA, using a socioecological framework. A sample of 133 pregnant women in two stages – at 10–12 weeks’ gestation (T1) and 20–22 weeks’ gestation (T2) – were evaluated. PA was assessed by accelerometry during the T1 and T2 evaluation stages. Socio-demographic characteristics, lifestyle factors and barriers to leisure PA were assessed via questionnaire. A large proportion of women (ranging from 32% to 96%) did not reach the levels of PA recommended by the guidelines. There were no significant differences between T1 and T2 with regard to compliance with PA recommendations. A decrease in PA levels from T1 to T2 was noted for all recommendations. No associations were found between participants’ characteristics and adherence to the recommendations in T1 and T2. No significant differences were found in barriers to leisure PA between T1 and T2. The most commonly reported barriers to leisure PA were intrapersonal, not health related. Our results indicate that there were no differences between trimesters regarding compliance of PA recommendations, and perceived barriers were similar in both trimesters. 相似文献
