The interaction between functional and dysfunctional emotions, as one of the major tenets of the individual zones of optimal functioning (IZOF) model (Hanin, 2000), was studied in a sport specific setting. Fourteen female gymnasts performed three attempts of a compulsory balance beam routine at three different heights. Heart rate and self-report of functional and dysfunctional emotions were measured during each routine. These data revealed the effectiveness of inducting emotions by manipulating height. Also, performance decreased on the most challenging condition, (i.e., the first attempt on the highest height). Moderated hierarchical regression analysis revealed a significant interaction between functional and dysfunctional emotions only when the dysfunctional emotion level was low.  相似文献

Most research related to learning in groups focuses on the unit of the group and/or group members. However, students may benefit from crossing the boundaries of their own group, as students in different groups may provide access to new, nonredundant knowledge and opportunities for learning. Whether boundary crossing between groups is beneficial for learning and academic performance has received limited conceptual and empirical attention. Using social network analysis and structural equation modeling, we contrasted pre/post network developments among 693 students (132 groups) across 4 modules at a UK business school. We examined whether it is better for students to invest in social relations in groups to learn and enhance academic performance or to (continue to) invest in social relations outside groups. Our findings indicated that students seemed to learn more from learning relations outside their group than from their own group members. Students with more intergroup relative to intragroup learning relations performed better on module assessments and throughout the academic year than students with more intragroup learning relations. Boundary crossing and intergroup learning deserves more empirical attention and experimentation on how to balance boundary crossing and effective group learning strategies.  相似文献

A large number of studies in CMC have assessed how social interaction, processes and learning outcomes are intertwined. The present research explores how the degree of self-determination of learners, that is the motivational orientation of a learner, influences the communication and interaction patterns in an online Problem Based Learning environment. Given the complexity of CMC, we expected that autonomous learners would be more willing to contribute to cognitive discourse. In time, we expected that control-oriented learners would develop a preferential attachment to contribute to discourse from autonomous learners. Data were gathered from 37 autonomous and 39 control-oriented learners who posted 1669 messages. Using a dynamic multi-method approach of content analysis of cognitive and social discourse, social network analysis, and measures of academic motivation, we find some preliminary evidence that motivational orientation influences communication and social interaction patterns amongst learners. From the beginning, most control-oriented learners develop a preference to connect to and communicate with autonomous learners, although a separate team-analysis indicates that group dynamics also influence how learners develop connections with other learners in time. Our findings further the understanding of differences found in distance learning courses about participation and drop-out.  相似文献

We investigate in the context of crowdsourcing how seekers can increase open innovation performance, measured as received solver attention, by making two strategic decisions: selecting innovation tasks that are well suited for crowdsourcing and choosing between the potentials of status signalling through identity disclosure versus enjoying the benefits of anonymity. Drawing on uncertainty reduction theory, we suggest that a well-articulated problem statement reduces uncertainties of potential solvers and increases their willingness to participate. We argue that the ability of seekers to draft high-quality problem statements depends on the distance between the problem domain and their current knowledge stock. An analysis of 637 crowdsourcing projects finds that problem-seeker knowledge distance and received solver attention are curvilinear related such that moderate levels of knowledge distance maximize solver participation. However, high-status seekers who engage in identity-based status signalling are able to benefit from crowdsourcing across all levels of problem-seeker knowledge distance.  相似文献

A multilevel modeling approach was employed to investigate the relation between sex composition and developmental change in 70 urban preschool classrooms. The research represents a unique contribution as (1) few studies have examined the influence of sex composition during the preschool years, (2) it represents the first research to use a continuous (i.e., sex ratio) as opposed to binary (i.e., mixed- versus single-sex) indicator for classroom sex composition, and (3) the sample represents an important and often neglected group (i.e., low-income children from urban schools). A series of HLM models were run, addressing the nested nature of the data (children within classrooms), and relating classroom sex composition to developmental change using the cognitive, motor, and social subscales from the Child Observation Record (COR). Overall, there were no main effects at the classroom-level for sex composition. However, a cross-level interaction indicated that, while girls’ development was not influenced by classroom sex composition, boys in classrooms with proportionally more boys fared significantly worse in terms of development as assessed by combined score on the COR. More specifically, this interaction was significant when predicting the COR cognitive subscale, but nonsignificant when predicting the COR social and motor subscales. This was true when controlling for the number of students at the classroom-level, as well as child's age and baseline ability (i.e., Time 1 COR) at the child-level. Implications for early childhood education policy are discussed.  相似文献

In recent years digital technologies, such as tablet personal computers (TPCs), have become an integral part of a school's infrastructure and are seen as a promising way to facilitate students' learning processes. This study empirically tested a theoretical model derived from the technology acceptance model containing key constructs developed in previous research on the acceptance of technological innovations. On the basis of the research model, it was hypothesized that students' acceptance of tablet PCs could be explained by key constructs and could be distinguished in organizational, individual, and technological factors. The survey research was conducted in three German middle schools, involving a total of 120 students. Overall, participants' attitude toward the TPC positively predicted their behavioral intention to use the TPC and as such had the strongest direct influence. The findings emphasize the importance of understanding factors affecting students' attitudes in order to manage and influence the integration of TPCs in schools.  相似文献

Since our first studies of information and communications technology (ICT) skills and ICT use at universities in 2004, ICT and its use by students has changed greatly. In order to obtain a more detailed picture of ICT skills, we first construct a new instrument to measure the self-perception of ICT skills (49 items) and of ICT use (53 items) by students. This allows us to find some patterns for ICT skills and ICT use. In order to explain these patterns, two basic hypotheses are formulated. The first suggests that positive ICT learning experiences at home, in school, and with peers could contribute to mastering a higher level of ICT skills and more frequent use of ICT among bachelor’s students, a hypothesis that aligns with Dewey’s learning theory. The second hypothesis suggests that there is a similarity between the characteristics of information systems and scientific research, and that students who identify more with scientific research would be more likely to have greater ICT skills and a higher frequency of ICT use. Both hypotheses are tested among bachelor’s students, using some important contextual variables (gender, domain of study, ICT course in secondary school or at university, and education level of parents). It can be concluded that there is a relationship between the ICT learning experience and the research-oriented identity commitment of bachelor’s students on the one hand, and their command of ICT skills and the frequency of use of computers, ICT instruments, and ICT programs on the other.  相似文献

A new approach to projects for undergraduate electronic engineering in an Australian university has been applied successfully for over 10 years. This approach has a number of projects running over three year period. Feedback from past graduates and their managers has confirmed that these projects train the students well, giving them the ability and confidence to work independently and collectively in the industrial world. Due to their importance to universities, staff and students alike, together with the potential heavy financial burden on the universities, careful planning has to be undertaken before implementing such projects. This paper presents some detailed suggestions on how such projects should be administered and operated as well as setting out possible criteria to assist supervisors in evaluating the final product from such projects.  相似文献
