Developmental stability and changes in the impact of root consistency on children’s spelling

The study reported here examined grade 2–4 children’s sensitivity to the consistency in the spelling of roots in related words. We build on earlier research by attempting to quantify the extent that children’s spellings of both inflected and derived forms accord with this principle. We contrasted children’s accuracy and consistency in spelling the root form (e.g., rock) with that of its spelling in related inflected and derived forms (e.g., rocks and rocky), as well as unrelated control forms (e.g., rocket). Across grades 2–4, children’s spellings accorded with the root consistency principle to the same extent for inflected and derived forms. Nevertheless, it was not until grade 4 that spellings maximally reflected the principle. These results are discussed in terms of how children’s spelling might come to reflect the root consistency principle that guides spelling in English.     

Faculty attitudes and training needs to respond the new European Higher Education challenges

The main objective of the Bologna Process is to create a “European space” for higher education that allows for comparability, compatibility, and coherence between the existing systems of higher education across Europe. This objective is commonly known as the European higher education area (EHEA). The creation of the EHEA is a new and specific challenge for higher education in Europe, one that depends upon improved faculty development and training across Europe. The integration of Spain and other European countries into European higher education more generally entails these challenges. In order for necessary changes in faculty development and training to take place, university managers and policy makers must account for designing training plans, as well the knowledge, attitudes and needs of faculty members. This investigation was undertaken with these themes in mind. Conducted in Madrid, Spain, it included 257 professors from ten different schools of the Universidad Complutense de Madrid. The aim of the investigation was to understand faculty knowledge and attitudes about changes in higher education in Europe. Moreover, with an eye to helping faculty members cope with the change that is accompanying the creation of EHEA, the investigators sought to understand the importance that faculty members place upon professional development and how current approaches to professional development at the university level could be improved. The results indicate a degree of ignorance regarding changes in European higher education as well as a feeling of resistance on the part of many faculty members. While many faculty members consider knowledge of change processes and adaptability to be important qualities, faculty responses also indicate a clear need for guidance if they are going to integrate new learning models and adequate coping strategies into their work in higher education.     

Cleaning the slate? School choice and educational outcomes in Spain

Using data from a nation-wide survey on Spanish workers, this paper examines two issues: the determinants of school choice (distinguishing between public and private schools) and the influence of school type on the individual’s educational attainment. For that, bivariate probit models are estimated. The analysis is carried out separately by gender and birth cohort. We find that individuals who have attended a private school come from households with higher socio-cultural level and that having attended a private school does not raise the probability of reaching a higher degree, once potential endogeneity of school choice and educational outcomes are taken into account. However, the latter result depends on the instrumental variable used for observed school type in models of demand for higher education.     

Social Guarantee Programme: principles for classroom procedure with students who have suffered failure at school – the Spanish educational system case

The article explores the Social Guarantee Programmes, one measure at attending to diversity within the Spanish educational system. It is an alternative measure that aims to break away from the organisational structure of Obligatory Secondary Education, seeking an organisational model and educational strategies that pursue satisfactory results through motivation, interest and the recovery of the student’s self‐esteem. The article presents the obtained results following ethnographic case study methodology. The research was performed in a secondary education school in a town in the province of Cadiz, Andalusia, Spain. The group chosen suffered significant learning difficulties and problems in adapting to schools. Our intention was to analyse and understand the relevant educational practices in the context of these programmes, since they were so innovative in nature.

Development and validation of Coaches’ Interpersonal Style Questionnaire

Purpose: The objectives were to develop and validate the Coaches’ Interpersonal Style Questionnaire. The Coaches’ Interpersonal Style Questionnaire analyzes the interpersonal style adopted by coaches when implementing their strategy of supporting or thwarting athletes’ basic psychological needs. Method: In Study 1, an exploratory factor analysis was performed with 265 Spanish male athletes, between 11- and 17-years-old, to confirm the internal structure of the questionnaire. Study 2 was conducted with 430 athletes, also between 11- and 17-years-old. Both confirmatory factor analysis and exploratory structural equation modeling were used to test a set of alternative models to find the best measurement model. Results: The hierarchical exploratory structural equation modeling model showed the best fit to the data and acceptable standardized factor loadings. Concurrent validity was revealed through correlational analysis of the basic psychological need satisfaction and frustration. Conclusion: This study provides a multi-dimensional questionnaire to assess coaches’ interpersonal style perceived by athletes.     

Comparison of two methodological approaches for the mechanical analysis of single-joint isoinertial movement using a customised isokinetic dynamometer*

Compared to isokinetic and isometric tests, isoinertial movements have been poorly used to assess single-joint performance. Two calculation procedures were developed to estimate mechanical performance during single-joint isoinertial movements performed on a customised isokinetic dynamometer. The results were also compared to appreciate the effects of measurement systems and calculation procedures. Five participants performed maximal knee extensions at four levels of resistance (30, 50, 70 and 90% of the one-repetition maximum, 1-RM). Joint angular velocity and torque were assessed from customised isokinetic dynamometer measures (method A) and from weight stack kinematic (method B). Bland–Altman plots and mean percent differences (M_diff) were used to assess the level of agreement for mean and peak angular velocity and torque. A Passing–Bablok regression was performed to compare the angular velocity-angle and torque-angle relationships computed from the two analysis methods. The results showed a high level of agreement for all mechanical parameters (M_diff < 6% for all parameters). No statistically significant differences were observed between methods A and B in terms of angular velocity-angle and torque-angle relationships except at 30% of 1-RM for the torque-angle relationship. Both methodologies provide comparable values of angular velocity and torque, offering alternative approaches to assess neuromuscular function from single-joint isoinertial movements.
