STRUCTURE OF PRIMARY MATHEMATICS TEACHER EDUCATION PROGRAMS IN SPAIN

Spain was 1 of the 17 countries that participated in the International Association for the Evaluation of Educational Achievement’s Teacher Education and Development Study in Mathematics (TEDS-M 2008). In this paper, we explore and describe the structure of Spanish primary mathematics teacher education programs. We analyzed the documents collected from the 48 sampled Spanish institutions that participated in TEDS-M. Our approach to the syllabus analysis focused on the established content dimension of curriculum in educators’ syllabi. These contents are structured into 4 knowledge domains—school mathematics, advanced mathematics, general pedagogy, and mathematics pedagogy—and categorized into subjects and topics. The results show that Spanish teacher education programs are diverse across institutions, but follow a basic structure that emphasizes the teaching of general pedagogy subjects.     

Trade in disembodied technology and total factor productivity in OECD countries

This paper searches for evidence of the importance of international trade in disembodied technology as a specific diffusion mechanism, using a sample of 16 OECD countries from 1971 to 1995. Consistent with previous research, this paper finds that there is international diffusion of technology. The measure for international trade in technology is OECD's Technology Balance of Payments statistics, which are country-level data on international transactions of disembodied technology. The econometric analysis explicitly takes into account non-stationarity of the variables, and for this reason, dynamic ordinary least squares (DOLS) is the estimation method used in the present study. The analysis shows that the effect of trade in disembodied technology on the importer's productivity varies across countries. Specifically, within OECD countries not in the G7 group, technology imports increase the host-country's total factor productivity, with the effect being stronger in the initial years of the sampling period. There is no evidence on this positive effect of technology trade on productivity in the case of G7 countries.

Users as innovators in developing countries: The global sources of innovation and diffusion in mobile banking services

This paper examines the extent to which users in developing countries innovate, the factors that enable these innovations and whether they are meaningful on a global stage. To study this issue, we conducted an empirical investigation into the origin and types of innovations in financial services offered via mobile phones, a global, multi-billion-dollar industry in which developing economies play an important role. We used the complete list of mobile financial services, as reported by the GSM Association, and collected detailed histories of the development of the services and their innovation process. Our analysis, the first of its kind, shows that 85% of the innovations in this field originated in developing countries. We also conclude that, at least 50% of all mobile financial services were pioneered by users, approximately 45% by producers, and the remaining were jointly developed by users and producers. The main factors contributing to these innovations to occur in developing countries are the high levels of need, the existence of flexible platforms, in combination with increased access to information and communication technology. Additionally, services developed by users diffused at more than double the rate of producer-innovations. Finally, we observe that three-quarters of the innovations that originated in non-OECD countries have already diffused to OECD countries, and that the (user) innovations are therefore globally meaningful. This study suggests that the traditional North-to-South diffusion framework fails to explain these new sources of innovation and may require re-examination.     

Effects of volleyball match-induced fatigue on knee joint position sense

Abstract

It has been suggested that a greater number of injuries during the last third of practice sessions or matches could be related to alteration of lower limb neuromuscular control due to neuromuscular fatigue. This fatigue-related effect can be mediated by changes in joint proprioception. In athletes, the use of functional fatigue protocols could have the advantage of mimicking the demands of sporting activity, thus reflecting more specifically the changes in neuromuscular control and proprioception observed in sport settings. The purpose of the present study was to assess the effect of fatigue induced by a volleyball match on knee joint position sense in elite volleyball players. Seventeen female volleyball players aged 18.9±4.2 years from the Portuguese national team volunteered for the study. Knee joint position sense was evaluated by an open kinetic chain technique and active knee positioning, and was reported using absolute, relative, and variable angular errors. Joint position sense measures were obtained before and immediately after a simulated volleyball match of five sets. To ensure that the match was sufficiently intense to induce fatigue, the perceived exertion or exercise intensity was assessed at the end of the match using Borg’ s rating of perceived exertion (RPE) scale. All participants completed the volleyball match (90min duration), reaching or exceeding 15 on the RPE scale (15.59±0.71; range 15–17), equivalent to “hard/heavy work”. After the volleyball match, a significant increase in absolute (2.11°) and relative (1.71°) angular errors was detected. Match-induced fatigue significantly exacerbated the overestimation of the test position. Moreover, the reliability and accuracy in estimating knee angles decreased from rest to the fatigued state, as shown by the increase (264%) in variable error. Our results show that fatigue induced by a volleyball match has a marked effect on knee joint position sense in elite female volleyball players. Knee joint position sense was less accurate and less consistent after the volleyball match. Fatigue induced by a simulated competitive volleyball match resulted in proprioceptive deficits, decreasing sensorimotor system acuity in female volleyball players.     

Benefits of achieving vigorous as well as moderate physical activity recommendations: Evidence from heart rate complexity and cardiac vagal modulation

Abstract

The aim of this study was to examine differences in traditional heart rate variability measurements and heart rate complexity (sample entropy) in young adults grouped by objectively measured achievement of either moderate or both moderate and vigorous physical activity recommendations. Of 168 young adults tested (86 females, 82 males; age 20.5 ± 1.2 years), 119 achieved only recommendations for moderate physical activity (moderate group) and 49 achieved recommendations for both moderate and vigorous physical activity (vigorous group). Analysis of covariance controlling for sex, weekly minutes of moderate physical activity, and percentage of body fat was used to assess between-group differences in heart rate variability and heart rate complexity. Logistic regression analysis was used to determine the group characteristics that best predicted high heart rate complexity and vagal indices of heart rate variability. The majority of the autonomic measures were higher (P < 0.05) in the vigorous group, and regression analysis showed that vigorous physical activity was the only multivariate predictor of higher heart rate complexity and higher heart rate variability. Young adults engaged in regular vigorous physical activity were more than twice as likely to have high heart rate complexity than those involved in predominantly moderate exercise. These findings suggest that vigorous physical activity is more closely associated with high heart rate complexity than moderate physical activity in young adults.     

Interpersonal dynamics and relative positioning to scoring target of performers in 1 vs. 1 sub-phases of team sports

Abstract

In this study, we examined the effects of relative positioning of attacker–defender dyads to the basket on interpersonal coordination tendencies in basketball. To achieve this aim, four right-hand dominant basketball players performed in a 1 vs. 1 sub-phase, at nine different playing locations relative to the basket (from 0° to 180°, in 20° increments). Performers’ movement displacement trajectories were video-recorded and digitized in 162 trials. Results showed that interpersonal coordination tendencies changed according to the scaling of the relative position of performers to the basket.

Stable in-phase modes of coordination were observed between performers’ longitudinal and lateral displacements (50.47% and 43.02%) on the left side of the court. On the right side of the court, a shift in the dominant mode of coordination was observed to a defender lead-lag of ?30°, both for longitudinal and lateral displacements (30.51% and 32.65%). These results suggest how information about dribbler hand dominance and relative position to the basket may have constrained attacker–defender coordination tendencies in 1 vs. 1 sub-phases of basketball.     

Perceived coach-created and peer-created motivational climates and their associations with team cohesion and athlete satisfaction: evidence from a longitudinal study

Abstract

In this longitudinal study, we examined the extent to which perceived coach- and peer-created motivational climates are associated with athlete-group cohesion and satisfaction with participation among Spanish soccer players competing in the Third National Division. Multilevel modelling analyses showed that perceived coach-created task climate was positively related to perceived cohesion and players’ satisfaction with their participation within their team. Also, perceived peer-created task climate related positively to perceived cohesion. The results indicate the importance of considering peer-related aspects of the motivational climate in addition to considering the coach-related aspects of the motivational climate when examining motivational group dynamics in sport.     

VICAID: Development and evaluation of a palmtop-based job aid for workers with severe developmental disabilities

The development of technologies to assist people with severe and profound developmental disabilities to engage in constructive activity without constant support from carers may assist such persons to participate fully in vocational and other occupational activities. We describe the development, evaluation and use of VICAID, a system based on a radically simplified palmtop computer. The VICAID system enables a person with a developmental disability to access pictorial instructions designed to help him or her in the accurate completion of tasks. It also provides reminders to access the instructions, and/or alerts a job coach or supervisor should the worker's interaction with the system suggest that they are having difficulty with a task. Evaluative studies show that (1) the system is more effective than alternative supports (pictorial instructions presented in booklets) in maintaining accurate task performance, (2) that the system is preferred to such booklets by most users with severe disabilities, and (3) that it can be used in real work settings. Future development of the system will require attention to be paid to issues of training job-coaches and support workers in its setting-up and maintenance.     

Teacher training colleges in the rural areas of Angola

The Aid for the Development of the People by the People (ADPP), a non-governmental organization (NGO), in collaboration with Angola’s Ministry of Education, has set up a network of secondary schools to train teachers to work in primary schools in the rural areas of Angola. These schools, called Training Colleges for the Teachers of the Future (CTFs), are involved in training a new type of teacher. This article discusses this educational practice, the main aim of which is to train primary teachers to work in the rural areas where too few trained teachers are willing to be posted. The authors describe the measures taken to better meet the needs of the rural areas in terms of teachers who have been properly trained and are motivated to work in such an environment, and then go on to analyse the reasons underlying the success of the CTF programme, specifically the fundamental differences from the state-run teacher training colleges, the way this new practice forms part of the overall reform of the education system and its role in the Education for All (EFA) initiative, and the fight against poverty.
