Abstract

The creation of a Personal Learning Environment (PLE) process. The research project Dipro 2.0 had different objectives, one of which was the creation of a learning environment using Web 2.0 architecture. This was done in three stages: the design of a prototype, an analysis by members of the research team and its evaluation by experts and students. The first environment is a PLE and the second environment contains the learning materials distributed in 14 units. Fifty-seven educational technology experts from different Latin American countries participated in the evaluation of both environments; they were selected from the criterion of expert competence and 284 students from different Spanish universities. The instrument used was created ad hoc, and results confirmed that both environments are positively valued; it is recommended for teacher training.  相似文献   

When Energy Conservation Seems to Fail: The Prediction of the Neutrino     

Francesco Guerra  Matteo Leone  Nadia Robotti 《Science & Education》2014,23(6):1339-1359

A historical case study concerning the serious doubts that arose in early 1930s about the validity of the law of energy conservation in nuclear disintegrations, and the hypothesis of neutrino, will be closely analyzed with the goal of promoting understanding of the nature of science. This work is based upon primary archival and printed sources, with a particular focus on the proceedings of the first International Conference of Nuclear Physics which was held in Rome on October 1931.  相似文献   

Connecting goals and actions during reading: the role of illustrations     

Josetxu Orrantia  David Múñez  Julio Tarín 《Reading and writing》2014,27(1):153-170

The ability to integrate information that is separated within a text, such as connecting a character’s action to a goal stated earlier in the text, is a critical factor in narrative comprehension. In the present study, we analyze the ability of 9- and 11-year olds to integrate such information. In addition, we examined the effect of illustrations on integration process by using on-line comprehension measures. Participants read narratives that conveyed a character’s goal early in the text, and an action was described later on that was either consistent or inconsistent with the goal. Narratives were presented either with an illustration that mirrored the situation described in the goal, or without an illustration. The results show that 11-year-olds spent more time on the inconsistent actions than on the consistent actions; in addition, 9-year-olds detected the inconsistency when illustrations were provided. An additional finding was that working memory moderated children’s ability to connect actions and goals. These results suggest that children as young as 9 years form connections between characters’ actions and their goals during text processing, although they need an illustration to keep the goal information activated to detect the inconsistency. Illustrations’ effectiveness was interpreted in terms of extra processing of the characters’ goal.  相似文献   

Misspoken in Arizona: Latina/o Students Document the Articulations of Racism     

Julio Cammarota 《Equity & Excellence in Education》2013,46(3):321-333

This article reports on racism expressed by school personnel (administrators and teachers) and experienced by Latina/o students at a high school located in Tucson, Arizona. Students in a specialized social science research program, called the Social Justice Education Project (SJEP), documented personal encounters with racist articulations at their school. After students conducted observations of their own interactions on campus, they would write (weekly) field notes as part of a research assignment to document racism in education. Most verbal exchanges influenced by racism can be categorized into direct racist statements or racial microaggressions. Both of these racist articulations are tantamount to derogatory comments or slurs that attempt to make an individual from a marginalized group feel inferior to or different (in a negative sense) from the dominant group. This article focuses on the SJEP, implemented at one particular Tucson high school, during the 2010–2011 school year. Excerpts from the students’ field notes pr esent evidence of racist articulations. The article concludes with recommendations on how to ameliorate the educational experiences of students of color with culturally relevant and responsive policies and practices that will move the discourse on marginalized groups in a positive direction.  相似文献   

Performance Indicator Maps: A Visual Tool for Understanding,Managing, and Continuously Improving Your Business Metrics     

Ingrid Guerra‐Lpez 《Performance Improvement》2013,52(6):11-17

Organizations are complex systems that require managers and employees alike to understand the interdependencies between their performance accomplishments and those of others, as well as the specific means and actions that affect them. Performance indicator maps (PIMs) are graphical representations that illustrate the relationships among organizational performance indicators. When properly designed, performance indicator maps can increase the effectiveness of feedback generated by dashboards, trigger tangible improvement actions today, and allow us to get the results we want tomorrow.  相似文献   

Home advantage in judo: A study of the world ranking list     

Ursula Ferreira Julio  Valéria Leme Gonçalves Panissa  Bianca Miarka  Monica Yuri Takito  Emerson Franchini 《Journal of sports sciences》2013,31(2):212-218

Abstract

In 2009, the International Judo Federation established a ranking system (RS) to classify athletes and to distribute the competitor quotas of the Olympic Games. However, the RS does not consider the home advantage. This issue has not been studied in judo, and its implications for the RS have not been determined. The objective was to verify the home advantage in judo in terms of winning a medal or the number of matches won. Therefore, 25 competitions that computed points for the RS in 2009 were analysed. Logistic regression analysis and the Poisson generalised linear model were used for the analyses, which included the relative quality of the athletes. The sample was composed only of athletes who had competed both at home and away. The odds ratio for winning medals was higher for athletes who competed at home for both males and females. The association between the number of matches won and competing at home was significant only for the male athletes. The home advantage was observed in the competitions that used the judo RS. Thus, it is likely that athletes from countries that host competitions using the RS have an advantage in terms of obtaining their Olympic classification.  相似文献   

Analysis of the distances covered and technical actions performed by professional tennis players during official matches

The purpose of this study was to analyse the physical and technical performances of professional tennis players during official matches. The trajectories of eight players were obtained during matches, using an automatic tracking method. The distances covered and technical performances were analysed for the first and second sets. The athletes covered (mean ± standard deviation) a total of 1702.4 ± 448.2 m in the first set, 1457.6 ± 678.1 m in the second set and 3160.0 ± 880.1 in the entire match. No differences were found between the sets for the physical variables (lateral and forward displacements, distance covered per rally, per game and per set, and the percentage of time spent in each range of velocity). However, the distances covered by the athletes during the rallies in which they were serving (median = 5.2; interquartile range (IQR) = 6.7 m) were statistically smaller than when they were returning (median = 6.2; IQR = 7.7 m). Forehand ground stroke proficiency decreased from the first (mean ± standard deviation: 75.2 ± 4.11%) to the second set (mean ± standard deviation = 65.5 ± 14.3%). In conclusion, tennis players did not present reduced physical performance from the first to the second set.  相似文献   

Colonizing Bodies: Corporate Power and Biotechnology in Young Adult Science Fiction     

Stephanie Guerra 《Children‘s Literature in Education》2009,40(4):275-295

The American cultural and political landscape has seen changes on the level of seismic shifts in the past four decades, thanks in part to the two very diverse fields of big business and biotechnology. Linking the two arenas together in the literary landscape is a growing body of young adult science fiction that envisions a future shaped profoundly by both. This paper surveys how the interplay between corporations and biotechnology is represented in this emerging body of work to explore diverse facets of a common theme: the biotechnical subjection of human matter to market force.  相似文献
