The purpose of this paper is to propose a training program for creative problem solving based on computer programming. The proposed program will encourage students to solve real‐life problems through a creative thinking spiral related to cognitive skills with computer programming. With the goal of enhancing digital fluency through this proposed training program, we investigated its effects. Two sets of experiments were performed in which 119 typical students and 30 younger, gifted students participated. Two synthetic creative problem solving tests, which had a high correlation with logical ability, scientific problem solving ability and divergent thinking ability, were developed to measure creative problem solving ability. We provided the treatment group with a paper‐based booklet with relevant problems developed specifically for that group. ANCOVA statistical procedures were used to analyze the pre‐ and post‐synthetic creative problem solving tests. The findings of our study are as follows: with typical students, the originality of the treatment group outperformed the control group, a result that was compatible with previous research. With gifted students, the fluency of the treatment group outperformed the control group, and overall creative problem solving ability was enhanced. Remarkably, fluency increased significantly, a notable difference from the results of prior studies. In conclusion, we inferred that, given the definition of digital fluency, if creative problem solving ability is enhanced by a training program for creative problem solving based on computer programming, digital fluency will ultimately be improved. In this paper, we discuss the result of fluency enhancement that contradicts prior research. We suggest that this training program could be a new learning environment for the students who have grown up with digital media.  相似文献

Combining innovation and efficiency is ideal in many organizational settings. Adaptive expertise represents a cognitive explanation of how individuals and teams can learn to achieve simultaneous innovation and efficiency. In 2004, scientists led twin rovers on Mars in the search for historical water. The science team experienced a remarkable increase in efficiency, adapting with flexibility to unexpected events and dynamic, dwindling resources. After discussing the conceptual differences between adaptive expertise and related team learning and innovation concepts, we examine longitudinal behavioral data on novelty, routine and adaptive expertise. Sequential time series ARIMA analyses reveal that novelty fluctuated randomly, but both routine and adaptive expertise significantly increased over time. In addition, novelty, routine expertise, and adaptive expertise did not significantly predict each other directly or at a lag, suggesting that these are indeed three distinct constructs. Implications for theory and research on efficiency and innovation are discussed. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

Two studies (N = 80; N = 91) investigated whether sharing an autobiographical memory increases empathy for a person experiencing chronic pain. Across studies, empathy was assessed after reading a pain‐related narrative of either a 25‐ or 85‐year‐old target and again after assignment to one of two recall conditions. Conditions involved recalling a pain‐related autobiographical memory (Studies 1 and 2), or as comparisons, recalling the target's pain narrative (Study 1) or recalling a character in pain from a movie (Study 2). Looking across both studies, empathy levels appear to increase after sharing an autobiographical memory but not in the comparison conditions. Increases in empathy were related to trait‐level agreeableness. When target‐age differences emerged (Study 2), participants felt greater empathy for the older person. Findings are discussed in terms of the function of autobiographical memory in eliciting pro‐social emotions such as empathy and implications for training empathic responding.

Purpose

This study examined the mediating role of perceived organizational support (POS) in the relationship between group-incentive participation and organizational commitment. The study also investigated the moderating role of innovation in the relationship between group-incentive participation and POS and the relationship between group-incentive participation and organizational commitment.

Design/Methodology/Approach

The proposed hypotheses were tested by hierarchical linear modeling by means of survey data that were collected in South Korea in 2008.

Findings

The results showed that the relationship between group-incentive participation and organizational commitment was fully mediated by POS. Cross-level analyses revealed that group-incentive participation had stronger relationships with POS and organizational commitment in more innovative companies than in less innovative companies.

Implications

These findings contribute to the literature by identifying the characteristics of organizations in which group-incentive participation is more effective. In particular, innovative companies could benefit from adopting group-incentive practices because these practices are more strongly related to POS and organizational commitment in more innovative companies.

Originality/Value

Whereas previous studies on group incentives have mainly focused on the effects of group incentives at the organizational level, this study bridged the gap between macro- and microapproaches through multilevel analyses. This study is unique in that it examined the vertical fit between group incentives and organizational characteristics while focusing on individual employees’ perceptions and attitudes.  相似文献

The effect of lead exposure on cognitive growth patterns was assessed in a longitudinal study of 196 children. Performances on tests of verbal comprehension and perceptual organization (Vocabulary & Block Design, Wechsler Intelligence Scales for Children) were measured at ages 6.5, 11 and 15 years. Growth curve analyses revealed that the quadratic model best described the relationship between test scores and age. Children with higher lead levels, as measured at age 15 years, demonstrated lower verbal comprehension scores over time and greater decline in their rate of Vocabulary development at age 15 years, as compared to children with lower lead levels. Lead exposure was not significantly associated with growth in perceptual organization test scores. Socioeconomic status and maternal intelligence were statistically significantly associated with growth patterns for both test scores, independent of the effects of lead. The findings suggest that lead negatively impacts the developmental progression of specific cognitive skills from childhood through adolescence.  相似文献

This paper argues that (cardinal) numbers are originally given to us in the context ‘Fs exist n-wise’, and accordingly, numbers are certain manners or modes of existence, by addressing two objections both of which are due to Frege. First, the so-called Caesar objection will be answered by explaining exactly what kind of manner or mode numbers are. And then what we shall call the Functionality of Cardinality objection will be answered by establishing the fact that for any numbers m and n, if there are exactly m Fs and also there are exactly n Fs, then m = n.  相似文献

This article refers to the results of a prospective effect evaluation study of three psychodynamic milieu-therapeutic institutions for children, which included cognitive and projective testing. After introducing milieu-therapy and explaining its roots in psychoanalytic and developmental thinking, the specific results of the research evaluation are outlined. It is found that environmental therapy is very efficient on the level of ego-functioning, but concern is expressed in regards to the relational abilities of the children. These findings are discussed in relation to the practical, organisational and theoretical principles of the actual treatment in order to find ways to improve our understanding of how milieu-therapy works and how it can be improved. Finally, we discuss the ways in which recent theoretical and empiric research emphasising the importance of the affect regulation and mentalisation can contribute to the psychoanalytic theories in the milieu-therapy.  相似文献

Applying social capital and systems theories of social processes, we examine the role of the classroom peer context in the behavioral engagement of low-income students (N = 80) in urban elementary school classrooms (N = 22). Systematic child observations were conducted to assess behavioral engagement among second to fifth graders in the fall and spring of the same school year. Classroom observations, teacher and child questionnaires, and social network data were collected in the fall. Confirming prior research, results from multilevel models indicate that students with more behavioral difficulties or less academic motivation in the fall were less behaviorally engaged in the spring. Extending prior research, classrooms with more equitably distributed and interconnected social ties—social network equity—had more behaviorally engaged students in the spring, especially in classrooms with higher levels of observed organization (i.e., effective management of behavior, time, and attention). Moreover, social network equity attenuated the negative relation between student behavioral difficulties and behavioral engagement, suggesting that students with behavioral difficulties were less disengaged in classrooms with more equitably distributed and interconnected social ties. Findings illuminate the need to consider classroom peer contexts in future research and intervention focused on the behavioral engagement of students in urban elementary schools.  相似文献

Using a nationally representative survey fielded in 2009, we analyze the relationships between personality traits and various modes of political participation in South Korea. We find statistically significant relationships between personality (measured by the Five‐Factor Model) and several nonelectoral modes of participation. Openness correlates positively with protest participation, rally attendance, financial contributions to political causes, news media contacts, and political activities via the Internet. Agreeableness correlates negatively with these five participation modes as well as petition signing. Conscientiousness is positively associated with individual political acts (e.g., contacting news media and elected officials and donation), while it is negatively associated with collective actions such as participation in rally. However, we do not find any significant relationship between personality and voter turnout. Reflecting an unusually conflictual political climate of South Korea in 2008, we discuss these findings' implications focusing on the personality‐situation interactions.  相似文献
