This paper discusses the possible applications of different types of experiment methods in innovation research. The paper argues that the experiment as a research method has been a largely missed opportunity in innovation research, in particular for creating applicable knowledge for businesses and organisations in the shape of new innovation tools and methods. The paper applies an analytically based limitation of the experiment method which includes an array of both quantitative and qualitative approaches. The use of experiments for such purposes is illustrated through a comparative study of four experiments concerning open innovation in service businesses and organisations. The case studies show how different experiment methods provide new opportunities for innovation research and how they can create new and applicable knowledge about open innovation. Thus the paper argues for applying experiments as an addition to other research methods in innovation research. 相似文献

The importance in studying Quality of School Life (QSL) lies predominantly on research findings concerning its relationship with educational outcome. Although some studies have focused on factors affecting QSL, no study so far has assessed various factors of QSL simultaneously, with regard to secondary education, in order to construct a QSL model and establish its best predictors. The present research has attempted to study correlates of QSL including demographic, personality variables and school stress, and construct a consistent model of QSL, using data derived from pupils in two Scottish secondary pupils (n = 425). The model constructed was found able to account for 56% of the QSL variance. Overall results indicated that QSL is predominantly associated with personality factors, in particular school self-esteem. Results are discussed in relation to the 'trait' character of QSL and the educational implications of the model. 相似文献

Child care services in Australia, for example, are largely defined and shaped by the historically dominant Anglo-Australian
discourse and norms. The aim of this research was to examine critically and to find meaning in the experiences of recently
arrived Sudanese families as they began to settle into their new cultural environment. The cultural values of some 30 Sudanese
families were investigated and related to how these affected the selection of child care services. Qualitative research methods
including an indigenous approach were used to gather data. Interactions with Sudanese families took place in their home environments.
Interviews were conducted in a way that put those people interviewed at ease. Techniques used included narrative interviewing
and vignettes. 相似文献

In the light of substantial improvements to the quality and availability of virtual reality (VR) hardware seen since 2013, this review seeks to update our knowledge about the use of head-mounted displays (HMDs) in education and training. Following a comprehensive search 21 documents reporting on experimental studies were identified, quality assessed, and analysed. The quality assessment shows that the study quality was below average according to the Medical Education Research Study Quality Instrument, especially for the studies that were designed as user evaluations of educational VR products. The review identified a number of situations where HMDs are useful for skills acquisition. These include cognitive skills related to remembering and understanding spatial and visual information and knowledge; psychomotor skills related to head-movement, such as visual scanning or observational skills; and affective skills related to controlling your emotional response to stressful or difficult situations. Outside of these situations the HMDs had no advantage when compared to less immersive technologies or traditional instruction and in some cases even proved counterproductive because of widespread cybersickness, technological challenges, or because the immersive experience distracted from the learning task. 相似文献

Spaced practice, or the distribution of practice opportunities across time, is a well‐known and effective practice for improving retention. However, spaced practice is not effectively implemented in schools, perhapsl as a result of a lack of educationally relevant research in the area. We conducted an educationally relevant investigation of the spaced practice. Using a quasi‐experimental between‐subjects design, we taught 62 third‐ and fourth‐grade students eight math vocabulary words under two patterns of spaced practice (fixed interval and expanded interval) and massed practice. Results showed a benefit of spaced practice over massed practice, but no difference between fixed interval and expanded interval spaced practice. The findings suggest that spaced practice may be implemented to improve the retention of math vocabulary words; however, more research is needed to provide guidelines to support educators in implementing spaced practice in schools. 相似文献

Actovegin, a deproteinized haemodialysate of calf blood, is suggested to have ergogenic properties, but this potential effect has never been investigated in human skeletal muscle. To investigate this purported ergogenic effect, we measured the mitochondrial respiratory capacity in permeabilized human skeletal muscle fibres acutely exposed to Actovegin in a low and in a high dose. We found that Actovegin, in the presence of complex I-linked substrates increased the oxidative phosphorylation (OXPHOS) capacity significantly in a concentration-dependent manner (19?±?3, 31?±?4 and 45?±?4?pmol/mg/s). Maximal OXPHOS capacity with complex I and II-linked substrate was increased when the fibres were exposed to the high dose of Actovegin (62?±?6 and 77?±?6?pmol/mg/s) (p?Vmax and Km were also increased in a concentration-dependent manner after Actovegin exposure (70?±?6, 79?±?6 and 88?±?7?pmol/mg/s; 13?±?2, 25?±?3 and 37?±?4?pmol/mg/s; 0.08?±?0.02, 0.21?±?0.03 and 0.36?±?0.03?mM, respectively) (p?相似文献
