Opis:
Non-typical letter activities and their effectiveness in foreign language lessons – EFL secondary school students’ perceptions The main aim of this article is to verify the effectiveness of non-typical lesson activities, involving the completion of a letter, in classroom conditions; and in implementing modern approaches to foreign language learning and teaching. Apart from presenting theoretical information on the notion of a letter and the concept of effectiveness in language education, the following account also provides insight into letter-based practical activities and identifies some consequences of their application in EFL classes. It delineates the opinions of secondary school students who, in an anonymous questionnaire, expressed their views on the letter activities offered to them in their lessons. Their opinions provide evidence in support of the content and concepts distinguished and discussed in the theoretical part of this paper.

Opis:
Scholars all over the world have been arguing for foreign language instruction which combines linguistic and cultural content. Eliminating the cultural side results in a deficient process. This study explored prospective teachers’ perceptions of both constituents, since they will ultimately be responsible for their implementation in the foreign language classroom. To this end, 137 students from three European universities were chosen and asked to fill out an online questionnaire with Likert scale items. Data was collected and interpreted using the free statistics software package R (R Core Team, 2019). The findings confirmed that the relevance of linguistic / cultural issues was unanimously acknowledged (98,5%), speaking was appointed as the most desired target skill (97,1%), interpersonal relations (88,3%) as the most important aspect of socio-cultural knowledge, and lessons with native speakers (94,2%) as the most relevant classroom resource

Opis:
This article deals with modelling and a flatness-based robust trajectory tracking scheme for a two degrees of freedom helicopter, which is subject to four types of tail rotor disturbances to validate the control scheme robustness. A mathematical model of the system, its differential flatness and a differential parametrization are obtained. The flat filtering control is designed for the system control with a partially known model, assuming the non-modelled dynamics and the external disturbances (specially the tail rotor ones) to be rejected by means of an extended state model (ultra-local model). Numerical and experimental assessments are carried out on a characterized prototype whose yaw angle (ψ), given by the z axis, is in free form, while the pitch angle (θ), which results from rotation about the y axis, is mechanically restricted. The proposed controller performance is tested through a set of experiments in trajectory tracking tasks with different disturbances in the tail rotor, showing robust behaviour for the different disturbances. Besides, a comparison study against a widely used controller of LQR type is carried out, in which the proposed controller achieves better results, as illustrated by a performance index.
