Returning after taking a break in online distance higher education: from intention to effective re-enrollment

One of online distance learning’s positive attributes is its flexibility. However, the possibility of engaging in periods of non-enrollment (breaks) usually ends in students dropping out. In this paper, the intention to continue of those students who have not enrolled in the second semester is analyzed, adopting a long-term program perspective. This continuance intention is compared with the subsequent restart (or dropping out) in the third semester. This analysis has confirmed that the models of continuance intention and effective re-enrollment are essentially different. Continuance intention is more rational, even logical, and is mainly based on the level of satisfaction or dissatisfaction with the educational experience (difficulty of the learning materials or perception of the learning system). Effective re-enrollment is more practical or pragmatic, with more importance given to the effects of student dimension variables, for example, motivations for studying, previous university experience, or environmental variables, such as having a job.     

On the role of impact evaluation of quality assurance from the strategic perspective of quality assurance agencies in the European higher education area

In this paper the current national legislations, the quality assurance approaches and the activities of impact analysis of three quality assurance agencies from Romania, Spain and Germany are described from a strategic perspective. The analysis shows that the general methodologies (comprising, for example, self-evaluation reports, peer reviews, on-site visits, assessment reports, follow-up measures) and main subjects of quality assurance in higher education (such as study programmes and institutional structures and processes) are very similar in the sample cases. However, up to now, impact evaluation of quality assurance has not been implemented systematically in the sample agencies (as in many others). This is the more relevant since the European standards of quality assurance in higher education oblige quality assurance agencies to analyse their general findings and observe the effects of their activities. Against that background, it is argued that methodologically sound impact analyses of quality assurance interventions in higher education institutions should be seen as an integral part of the agencies’ own quality assurance because it would make their work more transparent and easier to improve systematically. The paper identifies some professionalisation needs required for impact evaluation competences: staff and peers who are qualified by methodological knowledge but also by ‘soft’ skills such as project and conflict management.     

Was the Umayyad Caliphate of Cordoba as Strong as Arab Chroniclers Claimed?1

Arabic sources recall the tenth and early eleventh centuries as the time when Andalusian armies achieved their greatest military triumphs over the Christian kingdoms and counties of northern Iberia. Some of those victories were truly spectacular and their like would never happen again. However, this view is also the result of the concealment, justification, and minimisation of defeats, as well as of the exaggeration of the successes achieved. This follows from a critical reading of Muslim chronicles and from the study of the data provided by Latin sources. The present article discusses some of the aforementioned practices of chroniclers and analyses whether the image offered by Arab compilers overstated the true military potential of the Umayyad Andalusian Caliphate. It concludes that caliphal armies were already showing some alarming signs of weakness during this period.     

The virtual laboratory concept applied to strain measurements

In recent years the methodology of engineering education has been changing and many projects deal with improving the educational software. This paper reports on the virtual laboratory, a virtual environment applied to experimental analysis. The goals of the virtual laboratory are to introduce the laboratory environment to the student entering this world, so different from the typical theoretical lectures, for the first time, and to overcome the above-mentioned drawbacks. It should be mentioned that the virtual laboratory is not meant to replace highly enriching, practical experience, but rather is meant to train the individual, in order to improve his/her performance in later actual practice. The virtual laboratory experience starts with the study of strain measurements, an engineering technique widely used to measure deformations, strains, mechanical properties of materials and other variables which are used to analyse many problems.The strain measurement virtual laboratory is meant to offer the possibility of simulating experiences, undergone in a real laboratory, through the Internet. The student is expected to familiarize him/herself with the techniques, procedures, devices and theories in the laboratory environment.     

Resolución de problemas y uso de calculadoras

Resumen

El presente trabajo describe un programa para el entrenamiento en la solución de problemas que implican una sola operación básica (suma, resta, multiplicación y división) y presenta resultados de su aplicación a tres sujetos con las operaciones de suma y división. Otro aspecto del trabajo es la investigación del efecto del uso de calculadoras manuales en este tipo de tareas. Los resultados indican que ta aceleración del dominio de la mecánica de las operaciones obtenida con el uso de calculadoras permite a los sujetos un dominio conceptual de los problemas correspondientes a estas operaciones al menos tan bueno como el alcanzado en el caso de problemas y operaciones efectuados manualmente, dentro de los limites de los objetivos contemplados por el programa.

Two decades of curricular reforms in the Spanish university

In this article we present the topic of the orientation of university curricula, the pressures that exist today as a response to the demands of the market, and we examine specifically the transformation that has developed in Spain during the last two decades. We have tried to base the statements and analyses that are presented on empirical data obtained from our own research (Education and Labour Research Group—GRET). The motivation to write this document has been to try to add to the debate about the changes experienced by the university, in particular in regards to the curriculum, and to reflect on our experience as investigators in higher education.     

Antioxidant diet supplementation enhances aerobic performance in amateur sportsmen

The effects of antioxidant diet supplements on blood lactate concentration and on the aerobic and anaerobic thresholds and their adaptations to training were analysed. Fifteen amateur male athletes were randomly assigned to either a placebo group or an antioxidant-supplemented group (90 days supplementation with 500 mg x day(-1) of vitamin E and 30 mg x day(-1) of beta-carotene, and the last 15 days also with 1 g x day(-1) of vitamin C). Before and after the antioxidant supplements, the sportsmen performed a maximal exercise test on a cycle ergometer and maximal and submaximal physiological parameters were assessed together with blood lactate concentration. Maximal oxygen uptake (VO(2max)), maximal blood lactate concentration, and the maximal workload attained rose significantly in both groups after the 3 months of training. At the end of the study, maximal blood lactate concentration was lower in the group that took supplements than in the placebo group. The percentage of VO(2max) attained at the anaerobic threshold rose significantly in both groups after 3 months of training, although the final value in the supplemented group was higher than that in the placebo group. Antioxidant diet supplements induced lower increases in blood lactate concentration after a maximal exercise test and could improve the efficiency in which aerobic energy is obtained.     

Estimating the economic payoff to virtual university education: a case study of the Open University of Catalonia

This study extends the scope of research that examines the connection between physical attractiveness and student perception through a survey analysis. While other studies concentrate on physical attractiveness alone, we examined not only perceptions of attractiveness but its impact on students’ perception of knowledge, approachability and faculty selection in a hypothetical course. Using ordered logistic regression, logistic regression and ordinary least squares regression to examine the interaction between age, attractiveness, knowledge and approachability, our findings show that younger faculty members are perceived as more approachable and more attractive, while older faculty members are perceived as more knowledgeable. Faculty perceived as more attractive are also perceived to be more approachable. Further, we test the impact that these results have on faculty selection in a hypothetical course and find that students are more likely to select an attractive and approachable faculty member to take a course with, regardless of perceived knowledge of the faculty member. Overall, although the perception of beauty may be cursory, its results may not be when considering the primacy effect, role model effect and teaching effectiveness assessment.     

Do chimpanzees reason logically?

Psychologists disagree about the development of logical concepts such as or and not. While some theorists argue that infants reason logically, others maintain that logical inference is contingent on linguistic abilities and emerges around age 4. In this Registered Report, we conducted five experiments on logical reasoning in chimpanzees. Subjects (N = 16; 10 females; M = 24 years) participated in the same setup that has been administered to children: the two-, three-, and four-cup-task. Chimpanzees performed above chance in the two-cup-, but not in the three-cup-task. Furthermore, chimpanzees selected the logically correct option more often in the test than the control condition of the four-cup-task. We discuss possible interpretations of these findings and conclude that our results are most consistent with non-deductive accounts.
