Effectiveness of a digital literacy programme for primary education students / Efectividad de un programa de alfabetización digital para estudiantes de educación primaria     

Javier Fernández-Montalvo  Itziar Irazabal  José J. López-Goñi 《Cultura y Educación》2017,29(1):1-30

This study carried out an assessment of the effectiveness of a digital literacy programme for primary education students. A quasi-experimental design with repeated measures of assessment was used. The sample consisted of 364 students (206 male and 158 female) from the sixth year of primary education. The students were assessed in their own schools and the sample was divided into two groups: experimental group (N = 190) and control group (N = 174). The assessment was carried out in three sessions: pre-intervention, post-intervention and six-month follow-up. The programme was composed of three sessions aimed at improving digital literacy, as a way of developing a safe and responsible use of the internet. The results obtained after the intervention showed statistically significant differences in the comparison between the two groups. Specifically, the experimental group reached a significantly higher degree of digital literacy (conceptual, procedural and attitudinal) than the control group after passing through the programme.  相似文献

Reading Comprehension and Predictability Effects on Sentence Processing: An Event‐Related Potential Study     

ngel Javier Tabullo  Diego Shalom  Yamila Sevilla  Carolina Andrea Gattei  Luis París  Alejandro Wainselboim 《Mind, Brain, and Education》2020,14(1):32-50

Electrophysiology studies have identified two event‐related potentials that are modulated by predictive processes during language comprehension: the N400 and a frontal positivity. The N400 is smaller when words are presented within highly restrictive sentences, indicating reduced lexical retrieval costs. Violations of strong predictions generate larger frontal positivities, possibly reflecting inhibitory processes. More skilled comprehenders may exhibit enhanced predictive processing, but this possibility has seldom been investigated with event‐related potentials (ERPs). We analyzed the association between predictability ERP modulations and reading comprehension abilities. Twenty‐four undergraduate students were exposed to strongly and weakly constraining sentences, ending with an expected or unexpected final word. Their comprehension skills were assessed with a cloze task. Better comprehenders showed smaller N400s for expected words, and larger posterior positivities for unexpected endings, in strongly constraining contexts. These effects correlated with reading comprehension scores. The results suggest that better comprehenders take more advantage of predictions to reduce retrieval costs, and allocate more resources to postlexical integration processes.  相似文献   

“I Forgot I Wasn’t Saving the World”: the Use of Formative and Summative Assessment in Instructional Video Games for Undergraduate Biology     

Kathryn L. Lookadoo  Eryn N. Bostwick  Ryan Ralston  Francisco Javier Elizondo  Scott Wilson  Tarren J. Shaw  Matthew L. Jensen 《Journal of Science Education and Technology》2017,26(6):597-612

This study examined the role of formative and summative assessment in instructional video games on student learning and engagement. A 2 (formative feedback: present vs absent) × 2 (summative feedback: present vs absent) factorial design with an offset control (recorded lecture) was conducted to explore the impacts of assessment in video games. A total of 172 undergraduates were randomly assigned to one of four instructional video game conditions or the control. Results found that knowledge significantly increased from the pretest for players in all game conditions. Participants in summative assessment conditions learned more than players without summative assessment. In terms of engagement outcomes, formative assessment conditions did not significantly produce better learning engagement outcomes than conditions without formative assessment. However, summative assessment conditions were associated with higher temporal disassociation than non-summative conditions. Implications for future instructional video game development and testing are discussed in the paper.  相似文献   

Nutritional intake in soccer players of different ages     

Ruiz F  Irazusta A  Gil S  Irazusta J  Casis L  Gil J 《Journal of sports sciences》2005,23(3):235-242

The purpose of this study was to evaluate the dietary practices of soccer players of different ages. The diets of the members of four soccer teams (mean ages of 14.0, 15.0, 16.6 and 20.9 years, respectively) were examined. Our results show that the caloric intake per kilogram of body mass was significantly higher among the youngest players when compared with the adult players (P < 0.05). The contribution of carbohydrates to total energy intake was lower than that recommended for athletes. This contribution decreased with age from 47.4% of total energy intake for the 14-year-olds to 44.6% for the adult players. No significant differences in protein or total fat intake were detected among the teams examined. Overall, our results show that the nutritional intake of the soccer players was not optimal, and that this intake was poorer among the adult players than among the adolescents. On the basis of our results, we recommended that nutritional education should be given to soccer players at an early age and should continue throughout adolescence, not only with a view to improving performance but also to promoting more healthy dietary practices in the long term.  相似文献   

The teaching and research relationship within an institutional evaluation     

Javier Vidal  Miguel A. Quintanilla 《Higher Education》2000,40(2):217-229

The authors present an analysis of the relationshipbetween research and teaching in universities. The aimis to determine to what extent this relationship isstrong enough to support the idea that teaching andresearch should be analyzed together from aninstitutional evaluation point of view. Two mainquestions are presented: (a) should research beevaluated from an institutional point of view? And, ifso, (b) which specific aspects of research activitiescan be evaluated within each institution?Empirical data have been obtained within the SpanishNational Program for the Evaluation of Quality ofUniversities and there are supplemented by interviews. Evidence is found of strong connections between research and teaching and in particular areasanalysis of the two dimensions together willhelp in designing better improvement strategies foruniversities.  相似文献   

Male professional tennis players maintain constant serve speed and accuracy over long matches on grass courts     

Javier Maquirriain  Roberto Baglione  Marcelo Cardey 《European Journal of Sport Science》2016,16(7):845-849

The potential effect of fatigue on stroke production in tennis players is still controversial. The aim of this study was to analyse the tennis serve speed and accuracy in prolonged male professional matches played on grass courts. We analysed tennis serve statistics from five-set Wimbledon matches (n?=?15; 30 players). Results showed that match duration averaged 208.3?±?28.3?min. The overall serve speed was 177.0?±?10.2?km/h in the first set and 176.1?±?11.7?km/h in the fifth set (p?=?.34). The difference of all accuracy values of first set serves was not significantly different from those of the fifth set: percentage of valid first serves, 63.1?±?11.1% vs. 62.3?±?11.8%, respectively (p?=?.78); percentage of “aces”, 11.2?±?9.1% vs. 10.0?±?8.9%, respectively (p?=?.39); percentage of “winners”, 2.6?±?7.6% vs. 1.2?±?2.2%, respectively (p?=?.36); percentage of “double faults”, 2.8?±?3.0% vs. 2.8?±?3.4% (p?=?.97). In conclusion, tennis players were able to maintain constant serve speed and accuracy over five-set matches played on grass courts. Professional tennis players are capable of overcoming fatigue and/or make movement adjustments to effectively perform complex technical strokes like the serve throughout matches played on grass courts lasting more than 3?h in average.  相似文献   

Spanish validation of the Basic Psychological Needs at Work Scale: A measure to predict teachers’ well-being in the workplace     

Ángel Abós Catalán  Javier Sevil Serrano  José Antonio Julián Clemente  José Martín-Albo Lucas  Luis García-González 《International Journal for Educational and Vocational Guidance》2018,18(2):127-148

The present study aimed to validate a Spanish-version of the Basic Psychological Needs at Work Scale (BPNWS-Sp) and to examine the associations between needs satisfaction and engagement and burnout in secondary education teachers. Using a sample of 584 secondary education teachers, the results supported the three-factor model, composite reliability, measurement invariance, and nomological validity of the BPNWS-Sp. This study contributes to validating the first instrument in Spanish to measure the satisfaction of the three BPNs separately in secondary education teachers. The measurement of teachers’ BPNs could effectively provide guidance for school policies to improve teaching and learning.  相似文献
