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…
Company values guiding the recruitment of employees with a foreign background
2019
Purpose In this paper, the following research question is addressed: Why do business organisations recruit employees with a foreign background? This was examined in terms of the values that guide organisations and their management. The paper aims to discuss this issue. Design/methodology/approach The study focused on two businesses in Finland that are pioneers in the recruitment of immigrants. A case study approach was adopted. The research data consist of interviews and documentary data. The data were analysed using content analysis in accordance with grounded theory. Findings Companies can act as an enabling force in the integration of immigrants into the local labour market, especially …
Camouflage in arid environments: the case of Sahara-Sahel desert rodents
2020
Deserts and semi-deserts, such as the Sahara-Sahel region in North Africa, are exposed environments with restricted vegetation coverage. Due to limited physical surface structures, these open areas provide a promising ecosystem to understand selection for crypsis. Here, we review knowledge on camouflage adaptation in the Sahara-Sahel rodent community, which represents one of the best documented cases of phenotype-environment convergence comprising a marked taxonomic diversity. Through their evolutionary history, several rodent species from the Sahara-Sahel have repeatedly evolved an accurate background matching against visually-guided predators. Top-down selection by predators is therefore …
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…
On the road to systemic sustainability : how can cleantech facilitate the Finnish sustainability transition - a multi-layer perspective backcasting a…
2015
Sustainable development has been a dominant theme in international debate since inception. During the last decades it has gained momentum due to pressing challenges in the domains of agriculture, energy, transportation, raw materials, water and ecosystems. Finland ranks highly on many sustainable development benchmarks, but the success is imbalanced. For constructing long-term redundant sustainability and well-being, Finland needs a transition affecting policy, people and businesses. This study has an intertwined theoretical and applied objective, following a pragmatist approach. The theoretical objective is to develop a conceptual framework for analysing future oriented sustainability tran…
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…
Radio frequency fingerprinting for outdoor user equipment localization
2017
The recent advancements in cellular mobile technology and smart phone usage have opened opportunities for researchers and commercial companies to develop ubiquitous low cost localization systems. Radio frequency (RF) fingerprinting is a popular positioning technique which uses radio signal strength (RSS) values from already existing infrastructures to provide satisfactory user positioning accuracy in indoor and densely built outdoor urban areas where Global Navigation Satellite System (GNSS) signal is poor and hard to reach. However a major requirement for the RF fingerprinting to maintain good localization accuracy is the collection and updating of large training database. The Minimization…
