The Internet, overhead projectors and interactive boards, presentation and animation software, and online databases are only some resources that teachers use in order to present information in a more dynamic, immediate, and stunning way, transforming and revitalizing the teaching-learning process. The ICTs have been established in the university classroom and nowadays, they have become an essential part in this teaching-learning process. Lecturers make use of them in the same proportion as they make of traditional materials. At the same time, students have to be acquainted with these new technologies and they also have to be able to deal with them. The objective of this paper is twofold： On the one hand, we study and show how our students make use of the technologies when they have to face their oral presentations in the subject Advanced English： Professional Settings （English Studies Degree at Universitat Jaume I in Castellen, Spain）. It is acknowledged that visual aids can be helpful to support a speech, but we want to analyze if the visual aids are successfully applied, how and to which extent. On the other hand, we want to make out the opinions of their classmates about the use of these graphical resources （students fill in a questionnaire about the effectiveness of the visual aids in their classmates＇ presentations and how they would improve them）. Results demonstrate that not only teachers make advantage of the new technological resources, we show, based on the students＇ oral presentations and their peer-reviews, that also our university students are increasingly aware of the advantage and importance of the ICTs in the classroom.展开更多

A prospective case study was conducted on 15 children with history of CNS tumors with mean age of 10.47±1.85 y. Lighthouse distance, near visual acuity tests, cycloplegic refraction, reading speed measurement and visual field examination were done. Prescription of far and near LVAs followed by training sessions. LVPrasad-functional vision questionnaire was done to evaluate performance. Visual impairment was moderate(13.3%), severe(73.3%), profound(6.7%) and near blindness in 6.7%. Telescopes prescribed in 33.4%, video magnifier in 46.7%. Questionnaire scores were significantly improved for distant rather than near tasks(P≤0.05) after training. LVAs rehabilitation is an effective method of improving vision in pediatric visual defects secondary to CNS tumors.展开更多
