Influence of augmented reality technology upon pupils＇ knowledge about human digestive system： The results of the experiment     

Margarita Vilkoniene 《美中教育评论》2009,6(1):36-43

Applying information technologies in the educational process is the main direction of modern education. However, ＂moving＂ information communication technologies to schools is the primary purpose of discussions held by pedagogical and scientific society as this is a very problematic field （Lamanauskas, 2006）. Most of the researches show that the virtual learning environment help to achieve higher learning results. However, pupils＇ questioning in Lithuania, Germany, Romania, Malta and Czech （Lamanauskas, Vilkonis ＆ Klangauskas, 2007; Lamanauskas ＆ Vilkonis, 2007; Bilek, Zemanova ＆ Turcani, 2007） showed that most of the respondents prefer real learning environment or combine real and virtual environments while learning natural sciences. The latest scientific research shows that along the real and/or virtual teaching/learning environment, a combined environment can also be acceptable. The introduced environment can be created using augmented reality technology （ART）, i.e. augmenting real objects found in the environment and usual material visuals with virtual information in the real space. In Siauliai University, a pedagogical experiment was done, and it aims at establishing effective teaching/learning platform based on augmented reality technology （ARTP） influence upon the learning results. 110 pupils of the 7 th form of comprehensive school took part in the experiment. The analysis of the research data shows that pupils＇ achievement after use of ARTP in the experimental group significantly improved while completing some tasks.  相似文献   

Some grammatical rules are more difficult than others: The case of the generic interpretation of the masculine     

Pascal Gygax  Ute Gabriel  Oriane Sarrasin  Jane Oakhill  Alan Garnham 《European Journal of Psychology of Education - EJPE》2009,24(2):235-246

In this paper we argue that the generic use of the masculine represents a grammatical rule that might be easy to learn but difficult to apply when understanding texts. This argument is substantiated by reviewing the relevant literature as well as the recent work conducted by the GREL Group (Gender Representation in Language) on the interaction between stereotypical and grammatical information in the construction of a representation of gender when reading role names. The studies presented in this paper show that the masculine form used as a generic to refer to persons of both sexes, or to persons of indefinite sex or whose sex is irrelevant, in gender marked languages is likely to be associated with its specific meaning (i.e., masculine refers only to men). This is true even though the generic nature of the masculine is a very common grammatical rule learnt at school. People may have learned this rule and may understand it, but may not readily apply it.  相似文献   

The effect of sex and localised fatigue on triceps surae musculoarticular stiffness     

Aurélio Faria  Ronaldo Gabriel  Helena Moreira  Tanya Camacho  Rui Brás  Massimiliano Ditroilo 《European Journal of Sport Science》2018,18(4):483-490

Purpose: The main purpose of this study was to investigate the influence of fatigue on musculoarticular stiffness (MAS) of the ankle joint across sexes. Methods: Twenty-seven males and 26 females participated in the study. After baseline assessment of MAS and related variables, localised fatigue was induced in triceps surae using the standing heel-rise test during which the subjects were instructed to lift and drop the heel at a frequency of 0.5?Hz. When subjects were unable to continue due to exhaustion the test was terminated and another MAS test was performed soon after. Results: Significant higher triceps surae MAS was found in men compared to women (p?p??1 and from 14.5 to 13.9?KN?m^?1 in men and women, respectively. Percentage changes revealed, however, that in relative terms the changes in all the variables evaluated were similar (p?>?.01) between sexes, with MAS less than 5%. Conclusion: Despite the sex-related differences at baseline, fatigue seems to affect biomechanical properties of the ankle joint similarly in men and women.  相似文献   

The impact of Nordic adult education ideas on the development of a democratic society in Lithuania     

Margarita Teresevičienė  Elena Trepulė  Edita Trečiokienė 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2018,64(4):443-463

This article analyses the role of the cooperation with and the influence of the Nordic countries on the development of a democratic society in Lithuania through adult education since the reinstatement of its independence from Soviet regime in March 1990 to the present. The authors focus on three main areas: (1) the training of Lithuanian adult educators; (2) the establishment and development of NGOs; and (3) the implications for a Lithuanian policy of adult education. Within the framework of Nordic-Baltic cooperation established among five Nordic and three Baltic countries (NB8) in 1992, Lithuanian adult educators seized the opportunity to visit Scandinavian institutions and projects. Experiencing Nordic adult education ideas has resulted in a marked shift in Lithuanian adult educators’ values, methodology and careers; and in the establishment of a series of very influential umbrella associations as well as hundreds of NGOs in Lithuania which work with adults and support functioning democratic values in society. This shift is related to the civic responsibility and active participation growing out of the bottom-up approaches of group work, cooperation, discussions and learning circles which are so inherent in the Nordic tradition of adult education. The internalisation of new democratic values was more complicated than expected for many Lithuanian politicians, adult educators and NGO leaders in terms of how political decisions were perceived and implemented. Furthermore, the influence of the Nordic-Baltic cooperation in adult education may also be traced in adult education policy implications in Lithuania. Some changes in the policies of contemporary Lithuania have not been successful and even failed to promote a democratic society.  相似文献   

Assessing Measurement Invariance in Multiple-Group Latent Profile Analysis     

Margarita Olivera-Aguilar  Samuel H. Rikoon 《Structural equation modeling》2018,25(3):439-452

The study of measurement invariance in latent profile analysis (LPA) indicates whether the latent profiles differ across known subgroups (e.g., gender). The purpose of the present study was to examine the impact of noninvariance on the relative bias of LPA parameter estimates and on the ability of the likelihood ratio test (LRT) and information criteria statistics to reject the hypothesis of invariance. A Monte Carlo simulation study was conducted in which noninvariance was defined as known group differences in the indicator means in each profile. Results indicated that parameter estimates were biased in conditions with medium and large noninvariance. The LRT and AIC detected noninvariance in most conditions with small sample sizes, while the BIC and adjusted BIC needed larger sample sizes to detect noninvariance. Implications of the results are discussed along with recommendations for future research.  相似文献   

Clones identification of Sequoia sempervirens (D.Don) Endl.in Chile by using PCR-RAPDs technique

A protocol of polymerase chain reaction-random amplified polymorphic DNAs (PCR-RAPDs) was established to analyse the gene diversity and genotype identification for clones of Sequoia sempervirens (D.Don) Endl.in Chile.Ten (out of 34) clones from introduction trial located in Voipir-Viilarrica,Chile,were studied.The PCR-RAPDs technique and a modified hexadecyltrimethylammonium bromide (CTAB) protocol were used for genomic DNA extraction.The PCR tests were carried out employing 10-mer random primers.The amplification products were detected by electrophoresis in agarose gels.Forty nine polymorphic bands were obtained with the selected primers (BG04,BF07,BF 12,BF13,and BF 14) and were ordered according to their molecular size.The genetic similarity between samples was calculated by the Jaccard index and a dendrogram was constructed using a cluster analysis of unweighted pair group method using arithmetic averages (UPGMA).Of the primers tested,5 (out of 60) RAPD primers were selected for their reproducibility and high polymorphism.A total of 49 polymorphic RAPD bands were detected out of 252 bands.The genetic similarity analysis demonstrates an extensive genetic variability between the tested clones and the dendrogram depicts the genetic relationships among the clones,suggesting a geographic relationship.The results indicate that the RAPD markers permitted the identification of the assayed clones,although they are derived from the same geographic origin.  相似文献

Acute intraocular pressure changes during isometric exercise and recovery: The influence of exercise type and intensity,and participant´s sex     

Jesús Vera  Beatriz García-Durán  Alejandro Pérez-Castilla  Beatriz Redondo  Gabriel Delgado 《Journal of sports sciences》2013,31(19):2213-2219

ABSTRACT

We assessed the intraocular pressure (IOP) behaviour during a 1-minute period of isometric physical effort and the immediate 1-minute of recovery in the mid-thigh clean pull and squat exercises at three different intensities. Twenty physically active individuals performed the isometric mid-thigh clean pull and squat exercises at three intensities (0% [low-intensity], 25% [medium-intensity] and 50% [high-intensity] of the maximum isometric force). IOP was semi-continuously measured by rebound tonometry. There was a statistically significant effect of exercise intensity on IOP (p < 0.001, ?_p² = 0.416), observing that IOP increments were positively associated with exercise intensity. The mid-thigh clean pull and squat exercises did not demonstrate differences (p = 0.510), and also, no differences were observed between men and women (p = 0.683). The IOP changes during the isometric physical effort showed a positive linear behaviour in all conditions (r = 0.70 to 0.96). IOP returned to baseline levels after 8 seconds of recovery. Our data showed a progressive and instantaneous IOP increment during isometric exercise, which was positively associated with exercise intensity. IOP changes were independent on the type of exercise and participant´s sex. After exercise, IOP rapidly (≈ 8 seconds) returned to baseline levels.  相似文献   

Challenges to Cognitive Bases for an Especial Motor Skill at the Regulation Baseball Pitching Distance     

Jeffery P. Simons  Jacob M. Wilson  Gabriel J. Wilson  Stephen Theall 《Research quarterly for exercise and sport》2013,84(3):469-479

We tested expert baseball pitchers for evidence of especial skills at the regulation pitching distance. Seven college pitchers threw indoors to a target placed at 60.5 feet (18.44 m) and four closer and four further distances away. Accuracy at the regulation distance was significantly better than predicted by regression on the nonregulation distances (p < .02), indicating an especial skill effect emerged despite the absence of normal contextual cues. Self-efficacy data failed to support confidence as a mediating factor in especial skill effect. We concluded that cognitive theories fail to fully account for the patterns of observed data, and therefore theoretical explanations of the especial skills must address noncognitive aspects of motor learning and control.  相似文献   

Inclusive Education for Disabled Refugee Children: A (Re)Conceptualization through Krip-Hop     

Valentina Migliarini 《The Educational forum》2020,84(4):309-324

Abstract

Inspired by Hip-Hop pedagogy and the Krip-Hop movement, this paper aims to address the limits of inclusive education for disabled migrant students, by drawing on the community event “I am Hip-Hop” that took place in June 2019 in Italy. Through this community intervention, migrant and disabled migrant youth were provided a creative platform to reflect critically about their identity and journey. Ultimately, this paper offers teachers recommendations to anchor disabled migrant culture in educational practices.  相似文献
