Science and engineering students’ use of diagrams during note taking versus explanation     

Emmanuel Manalo  Yuri Uesaka  Sarah Pérez-Kriz  Masashi Kato  Tatsushi Fukaya 《Educational studies》2013,39(1):118-123

The use of diagrams in learning and communication is generally considered efficacious and an important skill to cultivate, especially among science students. At the same time, previous research has revealed many problems in student diagram use, including a lack of spontaneity in such use, but the extent to which these problems persist into the tertiary level had not been investigated. The present study examined science and engineering university students’ use of diagrams in note taking to learn information from a written passage, and in a subsequent task of constructing an explanation of that information for another person. The results showed that the students used significantly fewer diagrams in explaining compared to when they were note taking, suggesting that many students may lack awareness of the usefulness of diagrams in effectively communicating information to others. The results also revealed that the students used significantly more diagrams in taking notes from and explaining a passage with higher imageability (i.e. easier to visually imagine) compared to one with lower imageability. Educational implications of the findings are discussed.  相似文献   

Decreased Self-Reported Cognitive Failures after Memory Training     

Marek Preiss  Jiří Lukavský  Dana Steinová 《Educational gerontology》2013,39(9):798-808

In recent years, attention has been focused on investigating the effectiveness of composite memory intervention programs with different age and diagnostics groups. The goal of this study was to measure changes in cognitive lapses by Cognitive Failure Questionnaire (CFQ) in a large trained, dementia free group (Mini-Mental State Examination [MMSE] > 26). The CFQ was administrated to older adults before training (Wave 1), after training (Wave 2), and in a six-month follow-up (Wave 3) to an experimental (N = 77; memory training) and control sample (N = 78, no intervention). Significant changes in subjective cognitive functioning in the experimental group and a plateau curve in the control group were observed. The results indicate support for the efficiency of a large memory-training group in promoting subjective cognitive functioning.  相似文献   

Spelling well despite developmental language disorder: what makes it possible?     

Natalia Rakhlin  Cláudia Cardoso-Martins  Sergey A. Kornilov  Elena L. Grigorenko 《Annals of dyslexia》2013,63(3-4):253-273

The goal of the study was to investigate the overlap between developmental language disorder (DLD) and developmental dyslexia, identified through spelling difficulties (SD), in Russian-speaking children. In particular, we studied the role of phoneme awareness (PA), rapid automatized naming (RAN), pseudoword repetition (PWR), morphological (MA), and orthographic awareness (OA) in differentiating between children with DLD who have SD from children with DLD who are average spellers by comparing the two groups to each other, to typically developing children as well as children with SD but without spoken language deficits. One hundred forty-nine children, aged 10.40 to 14.00 years, participated in the study. The results indicated that the SD, DLD, and DLD/SD groups did not differ from each other on PA and RAN Letters and underperformed in comparison to the control groups. However, whereas the children with written language deficits (SD and DLD/SD groups) underperformed on RAN Objects and Digits, PWR, OA, and MA, the children with DLD and no SD performed similarly to the children from the control groups on these measures. In contrast, the two groups with spoken language deficits (DLD and DLD/SD) underperformed on RAN Colors in comparison to the control groups and the group of children with SD only. The results support the notion that those children with DLD who have unimpaired PWR and RAN skills are able to overcome their weaknesses in spoken language and PA and acquire basic literacy on a par with their age peers with typical language. We also argue that our findings support a multifactorial model of DLD.  相似文献   

Beyond formal R&D: Taking advantage of other sources of innovation in low- and medium-technology industries   总被引：1，自引：0，他引：1  

Lluís Santamaría  María Jesús Nieto  Andrés Barge-Gil 《Research Policy》2009,38(3):507-517

This study deepens our knowledge of critical success factors in the innovation process of low- and medium-technology (LMT) industries. To accomplish this, it explores how the innovation process in LMT firms may depend on non-formal R&D activities and the use of external sources. The empirical analysis is based on a representative panel of Spanish manufacturing firms. The results strongly support the view that non-R&D activities such as design, the use of advanced machinery and training are crucial to understanding the innovation process of any firm. The study finds, however, that the impact of these activities is especially important in LMT industries, particularly for the achievement of product innovations. The empirical evidence also reveals the importance of external sources such as the use of consultants, the hiring of personnel, collaboration agreements and external R&D, with the greatest differences between LMT and high-technology (HT) firms being observed in process innovations.  相似文献

Defining the problem: key element for the success of knowledge management     

Mario?Barcelo-ValenzuelaEmail author  Gerardo?Sanchez-Schmitz  Alonso?Perez-Soltero  Fernando?Martín Rubio  José?Palma 《知识管理研究与实践》2008,6(4):322-333

The objective of this paper is to propose a methodology for applying knowledge management (KM), in which we first focus on explaining problematic areas of an organization by identifying the knowledge core process, before applying KM strategies to those processes. For the methodology, we lean on the larger context of systems thinking to help visualize the whole organization, and it is here that the key factors are identified and a set of strategic criteria is established. The most important criteria are then used to evaluate the associated processes and their respective tasks in order to establish the problematic areas or opportunities where KM initiatives can be applied. This strategy precludes tackling all the organization's problems and allows management to focus on only those processes that provide significant and manageable knowledge. Finally, this study explores and cautiously recommends an unexploited but valuable element to be taken into account when implementing KM initiatives.  相似文献   

International research orientation of Swiss universities: self-regulated or politically imposed?     

Franz Horváth  Karl Weber  Martin Wicki 《Higher Education》2000,40(4):389-408

International openness is essential to science in small modern countries. The modernization of Swiss science and economy in the nineteenth century was promoted largely by foreigners: newly founded Swiss universities were staffed to a large extent by foreign professors, but students also came from abroad. Up to the middle of this century, the development of Swiss universities was marked by distinct successive phases of inviting in or shutting out international influence, depending mainly on changes in the political context. The international landscape of knowledge and science since the 1950s has undergone dynamic change. University structures were installed as a reaction to this dynamism. Patterns of international research orientation emerging in different universities and in the disciplinaryfields of business administration, chemistry and history are discussedin a comparative perspective.  相似文献   

Proofs produced by secondary school students learning geometry in a dynamic computer environment     

Ramón Marrades  Ángel Gutiérrez 《Educational Studies in Mathematics》2000,44(1-2):87-125

As a key objective, secondary school mathematics teachers seek to improve the proof skills of students. In this paper we present an analytic framework to describe and analyze students' answers to proof problems. We employ this framework to investigate ways in which dynamic geometry software can be used to improve students' understanding of the nature of mathematical proof and to improve their proof skills. We present the results of two case studies where secondary school students worked with Cabri-Géeomèetre to solve geometry problems structured in a teaching unit. The teaching unit had theaims of: i) Teaching geometric concepts and properties, and ii) helping students to improve their conception of the nature of mathematical proof and to improve their proof skills. By applying the framework defined here, we analyze students' answers to proof problems, observe the types of justifications produced, and verify the usefulness of learning in dynamicgeometry computer environments to improve students' proof skills.  相似文献
