Creativity: The role of unconscious processes in idea generation and idea selection

Today's world of continuous change thrives on creative individuals. Anecdotal reports suggest that creative performance benefits from unconscious processes. Empirical research on the role of the unconscious in creativity, though, is inconsistent and thus far has focused mainly on one aspect of the creative process - idea generation. This is the first study to assess the role of the unconscious mind for both idea generation and idea selection. Participants generated creative ideas immediately, after conscious thought, or after a period of distraction during which unconscious thought was hypothesized to take place. After having listed their ideas, participants selected their most creative idea. Performance in idea generation was similar between conscious and unconscious thought; however, individuals who had unconsciously thought about ideas were better in selecting their most creative idea. These findings shed more light on the role of unconscious processes in creativity, and provide a means to enhance creative performance.     

Community building of (student) teachers and a teacher educator in a school–university partnership

School?Cuniversity partnerships (SUPs) are considered a way of improving teacher education. For the successful implementation of such partnerships, cooperation between the different stakeholders is of crucial importance. Therefore, most partnerships are organised in short- and long-term teams, which are usually composed of teachers, student teachers and representatives of the university faculty. This study focused on the collaboration process of a team of modern language teachers who work and learn together in a teacher community. The aim of this study was to investigate how to design a learning environment that stimulates community development in these teams, applying the cooperative learning model of Johnson and Johnson in Learning together and alone: cooperative, competitive, and individualistic learning. Allyn and Bacon, Boston, (1999). Based on this model, design principles were developed to stimulate community development in this group. Community development was measured through observations of the meetings of the group, using the community model of Admiraal, Lockhorst and van der Pol described in this issue. The five principles found relevant in this SUP team were profiling the group as an identity, equivalent cooperation, rotating the chairperson, reflecting on the collaboration and giving feedback on the products made in the group.     

Rethinking Electronic Resources Workflows

After the technical service department at the University of Northern Colorado's James A. Michener Library underwent a major reorganization, Rick Kerns and his team were given the task to streamline and enhance various electronic resource workflows using internally developed tools. Kerns discussed the development of an interactive form to check e-journal holdings using a Microsoft Access database. He then described the Electronic Serial Correction Form and the Electronic Order Form, which were developed to change paper workflow into an electronic one, making the routing process easier and the forms clearer, more accurate, and searchable. A brief summary of this session, also authored by Ning Han, appeared in the “E-resource Roundup” column of the Journal of Electronic Resources Librarianship, Volume 23, Issue 1 (2011: March).     

Assessing the Relationship Between Perceived Message Sensation Value and Perceived Message Effectiveness: Analysis of PSAs From an Effective Campaign

The current study is an analysis of public service announcements (PSAs) from an effective safer sex campaign that utilized a sensation-seeking targeting (SENTAR) approach. Two random samples of heterosexually active young adults (sample one N = 1,463, sample two N = 895) viewed different sets of safer sex PSAs on a laptop computer and answered questions about their perceived sensation value and perceived effectiveness. Multiple regression analyses examined the impact of (a) demographic, (b) individual difference, (c) sexual context, and (d) message variables including perceived message sensation value (PMSV) on the perceived message effectiveness (PME) of the PSAs. Results indicated that females, African Americans, condom users, and those with less education viewed the PSAs as slightly more effective than males, Caucasians, non-condom users, and those with more education. PMSV and personal utility emerged as the strongest predictors of PME, even after controlling for all of the aforementioned variables. Implications for further research on PMSV and perceived and actual effectiveness of PSAs are offered.     

Scientific knowledge and attitude change: The impact of a citizen science project

This paper discusses the evaluation of an informal science education project, The Birdhouse Network (TBN) of the Cornell Laboratory of Ornithology. The Elaboration Likelihood Model and the theory of Experiential Education were used as frameworks to analyse the impact of TBN on participants’ attitudes toward science and the environment, on their knowledge of bird biology, and on their understanding of the scientific process. The project had an impact on participants’ knowledge of bird biology. No statistically significant change in participants’ attitudes toward science or the environment, or in participants’ understanding of the scientific process, could be detected. The results suggest that projects must make explicit to participants the issues that they are experiencing. In addition, the results suggest that more sensitive measures need to be designed to assess attitude change among environmentally aware citizens.     

Incorporating Concept Mapping in Project-Based Learning: Lessons from Watershed Investigations

The concept map tool set forth by Novak and colleagues is underutilized in education. A meta-analysis has encouraged teachers to make extensive use of concept mapping, and researchers have advocated computer-based concept mapping applications that exploit hyperlink technology. Through an NSF sponsored geosciences education grant, middle and secondary science teachers participated in professional development to apply computer-based concept mapping in project-based learning (PBL) units that investigated local watersheds. Participants attended a summer institute, engaged in a summer through spring online learning academy, and presented PBL units at a subsequent fall science teachers’ convention. The majority of 17 teachers who attended the summer institute had previously used the concept mapping strategy with students and rated it highly. Of the 12 teachers who continued beyond summer, applications of concept mapping ranged from collaborative planning of PBL projects to building students’ vocabulary to students producing maps related to the PBL driving question. Barriers to the adoption and use of concept mapping included technology access at the schools, lack of time for teachers to advance their technology skills, lack of student motivation to choose to learn, and student difficulty with linking terms. In addition to mitigating the aforementioned barriers, projects targeting teachers’ use of technology tools may enhance adoption by recruiting teachers as partners from schools as well as a small number that already are proficient in the targeted technology and emphasizing the utility of the concept map as a planning tool.     

特权用户阻碍IT建设

谈到商业智能(BI),专栏作家Rick Sherman说,商业用户和IT企业之间就此问题存在着种种矛盾。但人们并不用对此过于担心,因为商业智能取得成功的关键在于那些特权用户。你是否想过,为什么很多公司从商业智能销售商那里购买了具有成百上千功能的软件,却仅使用其中的少许功能?为什么企业的员工在他们的IT解决方案中已经选定了一个商业智能工具,并打算不使用微软公司的Ex- cel时候,仍然还使用Excel作为他们的     

Rats’ location during conditioned suppression training

Freezing is often cited as the interfering behavior responsible for barpress conditioned suppression. However, auditory cues that precede shock can evoke more freezing than can visual cues despite producing similar suppression. In two experiments, we sought to resolve this paradox by measuring rats’ location in the box in addition to recording freezing during conditioned-suppression training to tones and lights. Tone evoked more freezing than light but similar suppression. During both cues, rats left the bar and dipper areas and moved to the lower middle and rear of the box. When the bar was then removed and the dipper entry sealed, the preference for the middle and rear of the box disappeared. Apparently, frightened rats do not simply prefer the middle and rear of our box. The fact that rats leave the bar and dipper areas equally during both auditory and visual cues explains how the two cues can foster similar suppression despite evoking different levels of freezing. But the fact that rats leave the bar and dipper areas at all remains to be explained.     

Situating Expertise in Practice: Domain-Based Data Management Training for Liaison Librarians

The research data management team at the University of California, Berkeley implemented a domain-based Librarian Training Program in order to upskill liaison librarians in research data management principles and create a community of practice among librarians providing research data support. The training program partnered with representatives from each subject division of the Library to integrate content from relevant disciplines. The training model emphasized scaffolding and concrete deliverables, teaching specific tools and concepts, and creating learning objects useful for instruction and outreach. Employing a situated, learning-based, pedagogical model, the program was more successful than previous attempts at library-wide research data management training at Berkeley. This analysis details the program management, curricular design, instruction, and outcomes that made the Library Training Program successful.
