Finnish EFL learners' perceptions on errors, corrective feedback and foreign language anxiety
2012
Virheiden merkitys vieraiden kielten oppimisessa on tunnustettu aina 1970-luvulta lähtien, jolloin virheet alettiin nähdä välttämättömänä osana kielen ja sen sääntöjen oppimista. Virheiden tekemiseen vieraan kielen opiskelussa liittyy oleellisena osana opettajan oppijoille antama korjaava palaute (corrective feedback). Opettajan ja oppilaan vuorovaikutuksen, jota korjaava palaute osaltaan edustaa, on kuitenkin todettu voivan aiheuttaa oppijoissa ahdistuneisuutta ja pelkoa (anxiety). Tässä tutkielmassa kartoitetaan, millaisia suullisia virheitä suomalaiset yhdeksäsluokkalaiset englannin kielen oppitunneilla tekevät ja miten noloina he niitä pitävät. Tarkoituksena on myös selvittää, miten he …
Feedback Linearizing Control of Induction Motor Considering Magnetic Saturation Effects
2015
This paper presents an input-output feedback linearization (FL) control technique for rotating induction motors, which takes into consideration the magnetic saturation of the iron core. Starting from a new formulation of the dynamic model taking into consideration the magnetic saturation expressed in a space-state form in the rotor-flux-oriented reference frame, the corresponding FL technique has been developed. To this aim, a particular care has been given to the choice of nonlinear functions interpolating the magnetic parameters versus the rotor magnetizing current and the corresponding magnetic characteristic. The proposed FL technique has been tested experimentally on a suitably develop…
Vida más allá del PowerPoint: Un esfuerzo por superar la presente involución tecnológica de los procesos de enseñanza-aprendizaje hacia prácticas doc…
2018
La tradicional clase magistral se ha vestido o disfrazado, en el marco de la revolución digital, con tecnología para convertirse, en la pràctica, en una versión más cara y compleja, con grandes costes para los centros de enseñanza y universidades. Sigue siendo una lectura comentada por el profesor donde el alumno no tiene un papel activo, ya que es el profesor el que se considera que tiene el conocimiento, y trabaja. Los alumnos pueden preguntar si se considera necesario, ahora el estudiante no necesita ya tomar apuntes siquiera, las diapositivas de las editoriales carecen casi de erratas… Se propone con este poster dar un salto cualitativo siguiendo metodologías del mundo anglosajón para p…
Authentic assessment as a support for student teachers’ reflection
2023
Assessment and feedback guide learning. In light of this, the assessment practices of teacher education have received little research. This qualitative study examines student teachers’ discussions in a study unit built on authentic assessment practices: self- and peer assessment of videotapes from authentic performance with research-based rubrics. The aim is to investigate whether authentic assessment supports student teachers’ reflection and, if so, how. The findings show that authentic assessment led students frequently to reflection, and in most cases reflective discussions were induced by students’ self-criticism. We deduced that the encouraging feedback culture between students and bet…
Scaffolding self-regulated learning from causal-relations texts: Diagramming and self-assessment to improve metacomprehension accuracy?
2023
AbstractThe accuracy of students’ relative comprehension judgments when reading texts is typically rather low. This has been ascribed to students grounding their comprehension judgments on cues that are not diagnostic of their actual comprehension level. Asking students to complete causal diagrams—a diagramming scaffold—before judging comprehension has proved effective in providing them with more diagnostic cues and thereby fostered metacomprehension accuracy and self-regulated learning. However, there is still room for improvement. We investigated experimentally whether adding the instruction to students to self-assess their causal diagrams: (1) would lead to more accurate judgments than c…
Time-delay control for stabilization of the Shapovalov mid-size firm model
2020
Control and stabilization of irregular and unstable behavior of dynamic systems (including chaotic processes) are interdisciplinary problems of interest to a variety of scientific fields and applications. Using the control methods allows improvements in forecasting the dynamics of unstable economic processes and offers opportunities for governments, central banks, and other policy makers to modify the behaviour of the economic system to achieve its best performance. One effective method for control of chaos and computation of unstable periodic orbits (UPOs) is the unstable delay feedback control (UDFC) approach, suggested by K. Pyragas. This paper proposes the application of the Pyragas' me…
The Lorenz system : hidden boundary of practical stability and the Lyapunov dimension
2020
On the example of the famous Lorenz system, the difficulties and opportunities of reliable numerical analysis of chaotic dynamical systems are discussed in this article. For the Lorenz system, the boundaries of global stability are estimated and the difficulties of numerically studying the birth of self-excited and hidden attractors, caused by the loss of global stability, are discussed. The problem of reliable numerical computation of the finite-time Lyapunov dimension along the trajectories over large time intervals is discussed. Estimating the Lyapunov dimension of attractors via the Pyragas time-delayed feedback control technique and the Leonov method is demonstrated. Taking into accoun…
How do Finnish and Chinese students’ diverse pedagogical experiences shape feedback interpretation?
2023
Due to the dissemination of joint degree programmes in higher education, more students from different educational backgrounds are exposed to the same teaching and assessment without sharing a common pedagogical culture. Since this is relatively new in Finland, little is known about how students with diverse backgrounds experience assessment compared to their Finnish classmates and how this affects their overall performance. Having as a starting point an English for Specific Purposes course offered in Finland and China, this qualitative study focuses on the role of feedback through seventeen in-depth interviews. Themes such as grades and peer feedback were interpreted based on the educationa…
Might as well jump: Sound affects muscle activation in skateboarding
2014
The aim of the study is to reveal the role of sound in action anticipation and performance, and to test whether the level of precision in action planning and execution is related to the level of sensorimotor skills and experience that listeners possess about a specific action. Individuals ranging from 18 to 75 years of age - some of them without any skills in skateboarding and others experts in this sport - were compared in their ability to anticipate and simulate a skateboarding jump by listening to the sound it produces. Only skaters were able to modulate the forces underfoot and to apply muscle synergies that closely resembled the ones that a skater would use if actually jumping on a ska…
Mediadores psicológicos y motivación deportiva en judocas españoles. Psychological mediators and sport motivation in Spanish judokas.
2006
El presente trabajo analizo las diferencias de la motivacion en situacion precompetitiva de judocas en funcion de los mediadores psicologicos (percepciones de competencia, apoyo a la autonomia y relaciones sociales), tal y como postula el Modelo Jerarquico de la Motivacion Intrinseca, Extrinseca y Amotivacion (Vallerand, 1997, 2001; Vallerand y Losier, 1999). Se empleo una muestra de 181 judocas de edades comprendidas entre los 14 y 16 anos. Utilizamos una metodologia selectiva, con diseno prospectivo simple. Los datos se analizaron mediante un MANOVA, tomando como variables independientes los mediadores psicologicos y el sexo de los deportistas y como variables dependientes cada una de las…
