Job involvement in a career transition from university to employment

Job involvement–alienation was studied over three time points with a sample of undergraduate engineers undergoing a career transition from university to paid employment. Data from Newton and Keenan (1991) were re-analyzed under a latent growth curve modelling (LGCM) perspective, in order to provide an alternative analysis of the development of job involvement across that situational change, and to test the hypothesis that job involvement actually changed over that time period. University course satisfaction and anxiety were included as time-invariant predictors of growth, and compared to ascertain whether there would be differential effects of both predictors. The results supported the hypothesized relationships, indicating a significant growth in job involvement–alienation over time, with course satisfaction and course anxiety showing an equivalent impact on its change trajectory.     

Psicología cognitiva y educación

RESUMEN

Este artículo es un intento de acercar la psicología experimental cognitiva a la práctica educativa. La gran distancia que separa a ambas se debe tanto a la falta de validez ecológica de muchas investigaciones como a la novedad y complejidad de este modelo. Sin embargo, los métodos de análisis elaborados por los psicólogos cognitivos pueden contribuir a mejorar los métodos de enseñanza. Por ejemplo, los enfoques procesuales nos hacen comprender los mecanismos implicados en algunos saberes escolares, como en las matemáticas. Pero también plantean algunos problemas, ya que son muy sensibles a las variaciones del contexto y poco explícitos con respecto a los mecanismos de cambio de los procesos. Por ello, hay que completar los enfoques procesuales con enfoques estructurales, como el desarrollado por Piaget, que establece la génesis y el desarrollo de las estructuras de las acciones y las operaciones del sujeto y que propone la llamada pedagogía operatoria, que se concreta en la utilización de métodos activos de educación.     

Pensamiento y acción en el profesor: de los estudios sobre la planificación al pensamiento práctico

Resumen

Este artículo presenta una revisión crítica de la literatura de los últimos diez años sobre el tema del pensamiento y la intervención práctica del profesor. Se analiza la evolución de los estudios e investigaciones desde los planteamientos más cercanos al paradigma proceso-producto y mediacional, de marcado carácter psicológico, a los estudios alternativos, con mayor influencia filosófica y sociológica y que conceden mayor importancia a las estructuras de los contenidos del pensamiento del profesor.     

Financing higher education in Colombia

All countries and particularly the less developed face serious difficulties in the financing of higher education. This has also been true of Colombia, where private higher education has grown more rapidly than the official sector to the point of accounting for 60% of total enrollment due to the State's inability to increase the number of its institutions and to provide them with growing budgets.Given the greater efficiency in expenditure demonstrated by private institutions, a comparison is made of their income and expenditure structure with that of public institutions and differences are established in order to define those areas in which greater internal efficiency can be achieved.In spite of the total cost of higher education in Colombia it is relatively low due to the prevalence of low salaries and lack of equipment or sophisticated facilities and due also to the fact that research is still in an incipient stage.Faced with problems of fairness toward lower income families that must pay more than they can afford, or on the other hand, those who could pay more but are receiving free state education, a state subsidy is proposed to carry out a direct transfer to the student, while all state universities would charge tuition that would cover the cost of instruction. This subsidy should be channelled through ICETEX, a pioneer institution in the world in the field of student financing through credit. Several sources of student financing are examined that reflect a more realistic way of responsibly subsidizing study.     

Timescales for exploratory tactical behaviour in football small-sided games

The aim of this study was to identify the dynamics of tactical behaviour emerging on different timescales in football small-sided games and to quantify short- and long-term exploratory behaviour according to the number of opponents. Two teams of four professional male footballers played small-sided games against two different teams with a variable number of opponents (3, 5 and 7). Data were collected using a combination of systematic observation and a non-differential global positioning system (15 Hz). The temporal diversity and structural flexibility of the players were determined by calculating the dynamic overlap order parameter q, entropy and trapping strength. Analysis of the exploratory dynamics revealed two different timescales, forming a different metastable landscape of action for each constraint. Fast dynamics lasted on average a few seconds and consisted of changes in tactical patterns. The long timescale corresponded to the shared tasks of offence and defence lasting tens of seconds. The players’ tactical diversity decreased with an increasing number of opponents, especially in defence. Manipulating numerical imbalance is likely to promote changes in the diversity, unpredictability and flexibility of tactical solutions. The fact that the temporally nested structure of constraints shaped the emergence of tactical behaviour provides a new rationale for practice task design. The manipulation of numerical imbalance on the timescale of a few tens of seconds, on which the exploratory behaviour of players saturates, may help coaches to optimise the exploratory efficiency of the small-sided games.     

Factors influencing physiological responses to small-sided soccer games

Abstract

The aim of this study was to examine the effects of exercise type, field dimensions, and coach encouragement on the intensity and reproducibility of small-sided games. Data were collected on 20 amateur soccer players (body mass 73.1 ± 8.6 kg, stature 1.79 ± 0.05 m, age 24.5 ± 4.1 years, [Vdot]O_2max 56.3 ± 4.8 ml · kg^?1 · min^?1). Aerobic interval training was performed during three-, four-, five- and six-a-side games on three differently sized pitches, with and without coach encouragement. Heart rate, rating of perceived exertion (RPE) on the CR10-scale, and blood lactate concentration were measured. Main effects were found for exercise type, field dimensions, and coach encouragement (P < 0.05), but there were no interactions between any of the variables (P > 0.15). During a six-a-side game on a small pitch without coach encouragement, exercise intensity was 84 ± 5% of maximal heart rate, blood lactate concentration was 3.4 ± 1.0 mmol · l^?1, and the RPE was 4.8. During a three-a-side game on a larger pitch with coach encouragement, exercise intensity was 91 ± 2% of maximal heart rate, blood lactate concentration was 6.5 ± 1.5 mmol · l^?1, and the RPE was 7.2. Typical error expressed as a coefficient of variation ranged from 2.0 to 5.4% for percent maximal heart rate, from 10.4 to 43.7% for blood lactate concentration, and from 5.5 to 31.9% for RPE. The results demonstrate that exercise intensity during small-sided soccer games can be manipulated by varying the exercise type, the field dimensions, and whether there is any coach encouragement. By using different combinations of these factors, coaches can modulate exercise intensity within the high-intensity zone and control the aerobic training stimulus.     

What drives teacher engagement: a study of different age cohorts

Despite the growing body of research on work engagement, little is known about what drives work engagement among different age cohorts. This study aims to investigate whether engagement varies across age cohorts and examine the job resources that foster teacher engagement. A questionnaire was distributed to 537 teachers who were employed in elementary, lower and upper secondary school. Findings show that work engagement did indeed vary across the diverse age group and is influenced by different resources. In line with previous studies, data revealed that the engagement of younger teachers is driven by the opportunity for development and interaction with colleagues, while older employees appreciate the opportunity to see their competencies acknowledged. What is most noteworthy is the opportunity to design practices and to provide every age group with the appropriate set of motivators.
