Psychometric properties of the Portuguese version of the Éxamen Geronto-Psychomoteur (P-EGP)

ABSTRACT

Aging involves concomitant and interrelated changes in sensory, motor, and cognitive function. There is a decrease in psychomotor skills—such as balance, spatial orientation, mobility, and motor coordination—visible in increased difficulties performing daily instrumental activities (e.g., self care and domestic activities). The absence of valid psychomotor instruments for the elderly population to be used by psychomotor therapists can be identified as one of the reasons why there is a scarce research in this area. Currently, in Portugal, psychomotor therapists do not have any specific, validated scale within the psychomotor domain built and/or adapted to guide psychomotor interventions with the elderly population. Therefore, the aim of this study was the translation, adaptation, and validation of the Portuguese version of the Éxamen Geronto-Psychomoteur (P-EGP) in a population of 497 elders, aged between 60 and 99 years, with and without dementia. Results of the study are presented and discussed in terms of the reliability and validity of P-EGP. The results demonstrate that P-EGP appears to be a valid and reliable assessment of psychomotor skills for the elderly population in Portugal. Practical implications and future directions of research are also discussed.

Predicting volleyball serve-reception at group level

In a group-serve-reception task, how does serve-reception become effective? We addressed “who” receives/passes the ball, what task-related variables predict action mode selection and whether the action mode selected was associated with reception efficacy. In 182 serve-receptions we tracked the ball and the receivers’ heads with two video-cameras to generate 3D world-coordinates reconstructions. We defined receivers’ reception-areas based on Voronoi diagrams (VD). Our analyses of the data showed that this approach was accurate in describing “who” receives the serve in 95.05% of the times. To predict action mode selection, we used variables related to: serve kinematics, receiver’s movement and on-court positioning, the relation between receiver and his closest partner, and interactions between receiver-ball and receiver-target. Serve’s higher initial velocities together with higher maximum height, as well as smaller longitudinal distances between receiver and target increased the chances for the use of the overhand pass. Conversely, decreasing alignment of the receiver with the ball and the target increased the chances of using the underhand-lateral pass. Finally, the use of the underhand-lateral pass was associated with lower quality receptions. Behavioural variability’s relevance for serve-reception training is discussed.     

Enhancing the Popularity and the Relevance of Science Teaching in Portuguese Science Classes

PARSEL Project emerged from the urgent need to overcome the problem of lack of scientific literacy in the population, which should be a priority in a society where science occupies a central place. Indeed, nowadays for any citizen to participate in a responsible and informed way in society he has to be scientifically acknowledgeable. Nevertheless, not only are scientific levels low in the general population, but also there is an increasing number of students who avoid science and technology courses and related professions. Within this context, PARSEL aims at raising science and scientific courses’ popularity and relevancy as well as at enacting teachers’ professional development. In order to achieve these goals, the PARSEL group developed 54 pan-European modules, which were tested and evaluated by several teachers in several European countries and Israel. Teachers maintained a close relationship with the university, were highly encouraged to appropriate the modules and to adapt them to their local conditions and, also to discuss and share their experiences. In Portugal, modules were tested by a group of eight teachers, and their students. This paper presents data concerning teachers’ evaluation. Data was collected by means of interviews, observation and written documents and reveals that teachers positively evaluated PARSEL’s impact on their own professional development. Furthermore, they considered modules as well as the teaching-learning approach essential for making science learning relevant and popular for their students.     

Distance learning technology and service support in Greece: The case study of the Aristotle University over the last decade

In this paper we present the distance-learning (DL) environment of the Aristotle University of Thessaloniki, Greece. The technical infrastructure is based on synchronous DL facilities. DL classrooms have been used successfully over the last decade. We present a generic data model for DL service provision. Supplementary services have also been developed in order to provide support for the DL service provision. The use cases of the DL service are described. The pedagogical issues regarding both students and teachers have been investigated using statistical surveys. The findings are presented in this paper. Finally, the conclusion and future work is discussed.     

Student–teacher closeness and conflict in students with and without special educational needs

Teachers play a key role in creating effective conditions for students to succeed in school. The quality of student–teacher relationships is consistently associated with social, emotional, behavioural and academic adjustment, and this is even more relevant for students with special educational needs (SEN), considering these students’ emotional, social and learning vulnerabilities. This study aimed to examine the associations between students’ externalising and internalising behaviour, social skills and academic performance, and teachers’ perceptions of conflict and closeness in their relationships with students with and without SEN. Data regarding 360 students in Year 3, Year 5 and Year 7 (169 students with SEN) were collected. Teachers (n = 74) reported on the student–teacher relationship and students’ social skills, behaviour problems and academic performance. Special education teachers (n = 38) provided information regarding the diagnosis and profile of functioning of students with SEN. Results showed that teachers’ reports of students’ social skills and externalising problems were the strongest predictors of closeness and conflict. Internalising problems and SEN status also predicted decreased closeness, despite smaller effects. Taken together, findings support the importance of professional development opportunities focusing on facilitating teachers’ relationships with students with perceived challenging behaviour.
