Multicultural Visions of Globalization: Constructing Educational Perspectives From the East and the West     

Stephen R. White 《Interchange》2008,39(1):95-117

The thesis of this essay is that globalization is a phenomenon that humankind must be educated for understanding as a process of global evolution. The new world evolving is being defined as requiring a new sense of collective cooperation amongst the peoples of the Earth, if we are to continue to exist on the planet. Educators are in the midst of and have an important role to play in this social and conscious evolution. One of our challenges is to explore the theoretical foundations for framing a new global education agenda. The assertion is that the theories of global, social, and conscious evolution of 20^th century intellectuals and visionaries such as India’s Sri Ghose Aurobindo (1872-1950) and France’s Pierre Teilhard de Chardin (1881-1955) provide the foundation from which to construct a new global educational perspective.  相似文献

Classroom     

P. Jayanth Vyasanakere  K. Sudeesh 《Resonance》2008,13(8):768-771

In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. We may suggest strategies for dealing with them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences and viewpoints on matters related to teaching and learning science. This project was done as part of the Research Education Advancement Programme held over weekends at the Bangalore Association for Science Education, Jawaharlal Nehru Planetarium, Bangalore.  相似文献   

Effects of organizational pictures and modality as a feedback strategy on learner comprehension and satisfaction     

Albert D. Ritzhaupt  Raymond Pastore  Jiahui Wang  Robert O. Davis 《Educational technology research and development : ETR & D》2018,66(5):1069-1086

One of the strongest instructional interventions documented in educational literature is the use of feedback to influence learning outcomes. However, there is lack of empirical research specifically pertaining to the use of multimedia in the feedback message. The purpose of this research was to test whether organizational pictures and modality as a feedback strategy had an effect on learner comprehension and satisfaction. The research design was a 2 Multimedia (Picture Present vs. Picture Absent) × 2 Modality (Narration vs. On-screen Text) × Trial (Trial 1 vs. Trial 2) with Multimedia and Modality serving as between-subject conditions and Trial serving as a repeated measure. One-hundred fifteen university students participated in the study. Findings show statistically significant increases in comprehension scores from Trial 1 to Trial 2 assessments for all four treatment conditions. Learners in the Picture present conditions were statistically more satisfied with the learning experience. Additionally, we used eye-tracking to verify the extent to which the pictures were used in the feedback message. A discussion and recommendations for future research and feedback design are provided.  相似文献   

Tea polyphenols dominate the short-term tea (<Emphasis Type="Italic">Camellia sinensis</Emphasis>) leaf litter decomposition     

Dong-mei Fan  Kai Fan  Cui-ping Yu  Ya-ting Lu  Xiao-chang Wang 《Journal of Zhejiang University. Science. B》2017,18(2):99-108

Polyphenols are one of the most important secondary metabolites, and affect the decomposition of litter and soil organic matter. This study aims to monitor the mass loss rate of tea leaf litter and nutrient release pattern, and investigate the role of tea polyphenols played in this process. High-performance liquid chromatography (HPLC) and classical litter bag method were used to simulate the decomposition process of tea leaf litter and track the changes occurring in major polyphenols over eight months. The release patterns of nitrogen, potassium, calcium, and magnesium were also determined. The decomposition pattern of tea leaf litter could be described by a two-phase decomposition model, and the polyphenol/N ratio effectively regulated the degradation process. Most of the catechins decreased dramatically within two months; gallic acid (GA), catechin gallate (CG), and gallocatechin (GC) were faintly detected, while others were outside the detection limits by the end of the experiment. These results demonstrated that tea polyphenols transformed quickly and catechins had an effect on the individual conversion rate. The nutrient release pattern was different from other plants which might be due to the existence of tea polyphenols.  相似文献   

Opportunities to notice: Chinese prospective teachers noticing students’ ideas in a distance formula lesson     

Lin Ding  Higinio Domínguez 《Journal of Mathematics Teacher Education》2016,19(4):325-347

This paper investigates the noticing of six Chinese mathematics prospective teachers (PSTs) when looking at a procedural error and responding to three specific tasks related to that error. Using video clips of one student’s procedural error consisting of exchanging the order of coordinates when applying the distance formula, some variation was found in how PSTs attended to, interpreted, and responded to this error. A more important finding is represented by the inconsistent responses that individual PSTs provided to the three related tasks. This finding suggests that, to some extent, prior learning experience, beliefs, and orientations inform what PSTs notice. But the finding also suggests the centrality of selecting tasks that provide accurate representations of PSTs’ emerging professional noticing. Implications for teacher educators are discussed.  相似文献   

Development and Evaluation of Turkish Language Versions of three Positive Psychology Assessments     

Abdulkadir Haktanir  A. Stephen Lenz  Nesime Can  Joshua C. Watson 《International journal for the advancement of counseling》2016,38(4):286-297

This study reports the development and evaluation of a Turkish-language version of three positive psychology assessments for use in clinical, education and research settings with Turkish-speaking individuals. A multistage translation of the Brief Resilience Scale (BRS; Smith et al. in International Journal of Behavioral Medicine, 15, 194–200, 2008), the General Mattering Scale (GMS; Marcus 1991) and the Short Grit Scale (GS; Duckworth & Quinn in Journal of Personality Assessment, 91, 166–174. doi:10.1080/00223890802634290, 2009) is detailed, as well as the procedure used to evaluate the internal structure of the translated assessments. The results yielded from data of 268 participants indicated factor structures ranging from acceptable to robust model fit for the BRS, GMS, and GS. Implications for counseling practice and future research are discussed.  相似文献   

Effects on cytotoxicity and antibacterial properties of the incorporations of silver nanoparticles into the surface coating of dental alloys     

Xiao-ting Shen  Yan-zhen Zhang  Fang Xiao  Jing Zhu  Xiao-dong Zheng 《Journal of Zhejiang University. Science. B》2017,18(7):615-625

The aim of this study was to research the changes in cytotoxicity and antibacterial properties after silver nanoparticles (AgNPs) were incorporated into the surface coating of dental alloys. AgNPs were attached to cobalt chromium alloys and pure titanium using a hydrothermal method, according to the reaction: AgNO₃+NaBH₄→ Ag+1/2H₂+1/2B₂H₆+NaNO₃. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay was used to evaluate the cytotoxicity of the alloys when in contact with osteogenic precursor cells (MC3T3-E1) from mice and mesenchymal stem cells (BMSC) from rats. The antibacterial properties of dental alloys incorporating three different concentrations (10, 4, and 2 μmol/L) of AgNPs were tested on Staphylococcus aureus (SA) and Streptococcus mutans (MS). High cytotoxicity values were observed for all dental alloys that contained 0% of AgNPs (the control groups). The incorporation of AgNPs reduced cytotoxicity values. No significant difference was observed for antibacterial performance when comparing dental alloys containing AgNPs to the respective control groups. The results demonstrated that the cobalt chromium alloys and pure titanium all had cytotoxicity to MC3T3-E1 and BMSC and that the incorporation of AgNPs could reduce this cytotoxicity. The concentrations of AgNPs adopted in this study were found to have no antibacterial action against SA or MS.  相似文献   

The effectiveness of self-regulated learning scaffolds on academic performance in computer-based learning environments: a meta-analysis     

Lanqin Zheng 《Asia Pacific Education Review》2016,17(2):187-202

This meta-analysis examined research on the effects of self-regulated learning scaffolds on academic performance in computer-based learning environments from 2004 to 2015. A total of 29 articles met inclusion criteria and were included in the final analysis with a total sample size of 2648 students. Moderator analyses were performed using a random effects model that focused on the three main areas of scaffold characteristics (including the mechanism, functions, delivery forms, mode, and number of scaffolds; how to promote self-regulated learning by scaffolds); demographics of the selected studies (including sample groups, sample size, learning domain, research settings, and types of computer-based learning environments); and research methodological features (including research methods, types of research design, types of organization for treatment, and duration of treatment). Findings revealed that self-regulated learning scaffolds in computer-based learning environments generally produced a significantly positive effect on academic performance (ES = 0.438). It is also suggested that both domain-general and domain-specific scaffolds can support the entire process of self-regulated learning since they demonstrated substantial effects on academic performance. Different impacts of various studies and their methodological features are presented and discussed.  相似文献
