专题：科技信息的开发获取（一）[张晓林编委组织]

科技信息的开放获取已成为影响学术信息交流与科学发展的重大问题，深刻地影响到科技政策、科技支撑环境发展战略和科技信息服务模式。一大批科学家、科研机构和许多国家的科学管理与科研资助机构，都积极地推动科技信息的开放获取。他们或者制定开放获取政策、要求或鼓励科研人员提供科研成果的开放获取，或者支持开放出版期刊，或者建立机构开放存储库、支持本机构科研成果开放获取。通过这一系列的措施，科学界希望能够促进科研成果不受限制地广泛传播和自由获取、以及促进科研成果通过公共机制长期可靠保存和利用，以保障科技知识资产的国家保护和科研机构的知识资产管理。     

Topicalization and the Processing of Expository Prose by Children: mediating effects of cognitive styles and content familiarity

This study assessed the effects of text topicalization conditions (initial position, final position, or no topic sentence) on the comprehension of main ideas and specific passage information for middle school readers. Also of interest were interactions of topic familiarity and readers’ cognitive styles (degree of field independence) with text topicalization. One hundred and seven subjects were randomly assigned to one of the three topicalization conditions and read three familiar and three less‐familiar multipleparagraph expository texts. Main idea comprehension was assessed with both a sentencesummary (generation) and best‐title (recognition) task. Comprehension of specific passage information was evaluated with multiple‐choice items. Text topicalization effects were observed for main idea comprehension (with initial position best, followed by final position), while topic familiarity resulted in higher comprehension scores for specific passage information. Moreover, a cognitive style‐text topicalization interaction was found on the best‐title task; in this case, relatively field dependent readers were assisted by a final topic sentence placement. Implications are drawn for future research concerning the complex interplay of texts, tasks and readers in prose‐processing.     

Is Peer Interaction Necessary for Optimal Active Learning?

Meta-analyses of active-learning research consistently show that active-learning techniques result in greater student performance than traditional lecture-based courses. However, some individual studies show no effect of active-learning interventions. This may be due to inexperienced implementation of active learning. To minimize the effect of inexperience, we should try to provide more explicit implementation recommendations based on research into the key components of effective active learning. We investigated the optimal implementation of active-learning exercises within a “lecture” course. Two sections of nonmajors biology were taught by the same instructor, in the same semester, using the same instructional materials and assessments. Students in one section completed in-class active-learning exercises in cooperative groups, while students in the other section completed the same activities individually. Performance on low-level, multiple-choice assessments was not significantly different between sections. However, students who worked in cooperative groups on the in-class activities significantly outperformed students who completed the activities individually on the higher-level, extended-response questions. Our results provide additional evidence that group processing of activities should be the recommended mode of implementation for in-class active-learning exercises.     

Creating safe spaces for children’s voices to be heard: supporting the psychosocial needs of children in times of trauma

ABSTRACT

This reflection on practice provides a foundation for understanding the impact of Hurricane Harvey on teachers and children across the Texas Gulf Coast. It also documents the emergence of a professional development initiative born when early childhood teacher educators in the community outreach arm of a major university sought to provide immediate support for colleagues returning to their classrooms in the wake of the disaster. The initiative was designed to promote teachers’ understanding of the theoretical rationale behind supporting the psychosocial development of children in times of trauma and offer specific strategies and activities to help children work through this particular natural disaster, that is, storms, flooding, property destruction, and some physical harm. Implications for early childhood teacher preparation along with recommendations for future action are included.     

A Loyalty Tax? National Measures of Academic Salary Compression

This paper presents measures of faculty salary compression for 1993 and 1999 based on national, rather than institutional-level, data. Using a recently developed technique and two national faculty surveys, actual junior to senior salary ratios are derived as well as predicted salary ratios that represent what the salary ratios would be if junior and senior faculty were similarly compensated for their productive traits. The analysis, which considers three alternative definitions of junior faculty and stratifies results by institutional type, produces an overall finding of no salary compression. A limited number of disciplines, including business and economics, however, do exhibit signs of salary compression.     

Evaluation of a networked staff development strategy for departmental tutor trainers: benefits,limitations and future directions

As part of the 1997–1999 Teaching and Learning Enhancement Plan, the University of Queensland mandated that all its academic departments should conduct tutor training. The University's academic development unit, TEDI (the Teaching and Educational Development Institute) designed a network‐based staff development strategy for the development of departmental staff designated as tutor trainers. The strategy was known as the Tutor Training Network (TTN). This paper describes the strategy and reports on an evaluation of the Network programme. The data show that although it was very successful, the network‐based strategy has a limited lifespan. Nonetheless it is an effective strategy for wholesale staff development to support institution‐wide implementations of policy or changes in practice.
