Out-of-school learning in the botanical garden: Guided or self-determined learning at workstations?     

Franziska Wiegand  Alexander Kubisch  Thomas Heyne 《Studies in Educational Evaluation》2013

Guided tours are the method of choice for school classes visiting botanical gardens. However, it remains unclear, which influence such teacher-centered approaches have on learning outcome in such informal learning environments. We compare a teacher- to a student-centered learning at workstations program under the topic plants and water. 16 school classes at eighth grade visited the botanical garden of the University of Würzburg, attending either one of both treatments. We used multiple-choice questionnaires measuring knowledge scores and found no significant differences in learning outcome – tested in a pre-post-retention design. We also monitored the students’ intrinsic motivation, which resulted in similar and high scores. Possible causes for our results and consequences for education at botanical gardens are discussed.  相似文献   

How do students misunderstand number representations?     

Geoffrey L. Herman  Craig Zilles  Michael C. Loui 《Computer Science Education》2013,23(3):289-312

We used both student interviews and diagnostic testing to reveal students’ misconceptions about number representations in computing systems. This article reveals that students who have passed an undergraduate level computer organization course still possess surprising misconceptions about positional notations, two's complement representation, and overflow. Contrary to common opinion, these misconceptions are widespread and reveal the need for instruction that specifically targets these misconceptions. In addition, these misconceptions will serve as the basis for the creation of a standard assessment tool called the digital logic concept inventory. This concept inventory will provide a rigorous and quantitative metric to assess the effectiveness of new teaching methods.  相似文献   

The communication anxiety inventory: Validation of state‐and context‐communication apprehension     

Steven Booth‐Butterfield  Malloy Gould 《Communication quarterly》2013,61(2):194-205

Research reported in this paper investigates the reconceptualization (McCroskey, 1984) of communication apprehension (CA), focusing on the relationship between context‐CA and state‐CA. The validity of the reconceptualization can be enhanced by demonstrating that state‐CA (level of fear and anxiety) is systematically related to context‐CA (predisposition). Two research studies using a new operational measures of state‐CA and context‐CA, the Communication Anxiety Inventory, offer empirical support for the relationship between context‐CA and state‐CA. Results show that context‐CA explains a minimum of 50% of the state‐CA variance. Conclusions suggest that level of fear or anxiety varies closely with context‐CA and that the new scales have strong predictive validity.  相似文献   

供应链环境下中小民营企业库存管理模式探讨     

吴智峰 《武汉职业技术学院学报》2013,(5):17-20

基于随机理论的我国铁矿石库存优化     

许贵斌  赵旭  李雪婷 《上海海事大学学报》2013,34(4):76-81

为使铁矿石库存可以作为平衡铁矿石价格波动、协调铁矿石供给以及保障能源物资安全等的有效调节方式,研究需求随机变动情况下的铁矿石供应链库存优化方法,证明需求的变动对总库存成本的影响最大.因此在铁矿石供应链上,各级节点企业在生产经营过程中要做好对需求的分析与监控.各级节点企业需要进行有效合作,同时在生产经营过程中要做好对需求的分析与监控。  相似文献

The Conceptual Bases of Study Strategy Inventories   总被引：3，自引：0，他引：3  

Noel Entwistle  Velda McCune 《Educational Psychology Review》2004,16(4):325-345

This article describes the historical origins and development of a series of well-known study strategy inventories and seeks to identify their conceptual bases. The theories and evidence influencing the development of 6 contrasting instruments are considered before examining empirical evidence of similarities and differences between the measurement instruments. This analysis is tackled in three stages, looking first at inventories developed in the 1970s and 1980s that focused mainly on motivation, study methods, and learning processes. The more recent work that brought in mental models, metacognition, and self-regulation is then introduced, leading to a concluding section that discusses the conceptual bases of the whole set of inventories. The trends found in this research area are described and used to explore the current confusion of overlapping terms describing apparently similar aspects of learning and studying in higher education.  相似文献   

现代心理学关于社会支持研究的进展   总被引：5，自引：0，他引：5  

宋文琼  张守臣  李春华 《黑龙江教育学院学报》2008,27(6):79-82

现代心理学关于社会支持的研究可分为宏观和微观两个层次。宏观层次主要运用质性研究的方法;微观层次则多使用定量研究的方法。今后关于社会支持的研究将出现方法上的新进展;研究对象将更加广泛;研究结果将更多地运用于应用领域,指导人们获得和提供适宜的社会支持。  相似文献
