Incorporating teacher-student dialogue into digital course material : Usage patterns and first experiences
2020
This work-in-progress research investigates teacher-student communication via Learning Management Systems (LMS) in highly populated courses. An LMS called TIM (The Interactive Material) includes a specific commenting technology that attempts to make teacher-student dialog effortless. The research goal is to explore students’ willingness to use the technology and identify patterns of usage. To these ends, a survey with both Likert and open-ended questions was issued to CS1 and CS2 students. A favorable student evaluation was observed while several critical viewpoints that inform technology development were revealed. We noticed that besides appreciating the possibility of making comments, man…
Students’ comments about university teaching: which links with effectiveness models?
2015
Se presentan los resultados de un análisis temático de contenido sobre 550 comentarios dentro un proceso de evaluación instruccional en estudiantes de la Universidad de Mons. Se buscan vínculos entre las características del profesor eficaz según los estudiantes y una revisión de la literatura científica, contemplando, en primer lugar, la enseñanza efectiva en la educación primaria y secundaria, y en segundo lugar, se expone la valoración de las instrucciones acerca de los profesores en la educación superior. Los resultados informan de una relación entre los comentarios de los estudiantes y las instrucciones docentes, y que la gestión de aula del profesor dobla en dos veces a sus característ…
Tutkimus peruskoulun ja lukion opettajista Keski-Suomen alueella
2017
This study examined Information and Communications Technology (ICT) know-how and needs and challenges of teachers in-service training in the region of Middle–Finland. In this context impressiveness is seen as the congruence between the set aims and gathered results. The study approaches the subject matter through the opinions of teaching personnel. The study data was gathered from the focused interview questionnaires in many supplementary educational occasions of randomly picked teaching personnel in 2013, 2014, 2017 and also from personnel interwiew’s in 2013-2016. The study is aimed at the teaching personnel of Comprehensive Schools and Upper- Secondary Schools to investigate their ICT kn…
Numerical and Experimental Study of Friction Loss in Hydrostatic Motor
2012
Published version of an article in the journal: Modeling, Identification and Control. Also available from the publisher at: http://dx.doi.org/10.4173/mic.2012.3.2 Open access This paper presents a numerical and experimental study of the losses in a hydrostatic motor principle. The motor is designed so that the structural deflections and lubricating regimes between moving surfaces and, subsequently, the leakage and friction losses, can be controlled during operation. This is done by means of additional pressure volumes that influence the stator deflection. These pressures are referred to as compensation pressures and the main emphasis is on friction or torque loss modeling of the motor as a …
Imágenes y gestos en la fonética aplicada a la enseñanza de E/LE
2013
Cuando los profesores de E/LE enseñan la comunicación oral, se dan cuenta de que muchos estudiantes no pueden mantener una conversación por simple que esta sea debido, muchas veces, al escaso conocimiento que los alumnos tienen de la pronunciación. Una de las preguntas que se plantean los profesores, entonces, es la de cómo enseñar la fonética aplicada. En este artículo presentamos una experiencia de actividad didáctica innovadora, llevada a cabo con estudiantes universitarios francófonos. Esta actividad hace hincapié en las imágenes y en los gestos, y su objetivo es ayudar al estudiante a apropiarse correctamente de los sonidos que le causan mayor dificultad.
Eye-tracking the Effects of Representation on Students' Problem Solving Approaches
2017
This study used an eye-tracking method to explore students’ approaches to solving the same task in different representations and the differences between students who answered correctly and those who answered incorrectly when solving the problems. Thirty-one upper secondary students took part in the study. According to the results of this study, the representation has a slight effect on students’ problem solving processes. Students with the incorrect answers paid more attention to the parts of the tasks with information irrelevant to determining the solution to the task. peerReviewed
Tail Removal Block Validation: Implementation and Analysis
2018
In this paper a solution for the removal of long tail blocktimes in a proof-of-work blockchain is proposed, implemented and analysed. Results from the mainnet of the Bismuth blockchain demonstrate that the variances in the key variables, difficulty level and blocktime, were approximately halved after the tail removal code was enabled. Low variances in difficulty and blocktimes are desirable for timely execution of transactions in the network as well as reduction of unwanted oscillations in the feedback control problem.
Using assessment for learning mathematics with mobile tablet based solutions
2014
Published version of an article in the journal: International Journal of Emerging Technologies in Learning (iJET). Also available from the publisher: http://dx.doi.org/10.3991/ijet.v9i2.3219 This article discusses assessment for learning in mathematics subjects. Teachers of large classes face the challenge of regularly assessing students’ ongoing mathematical learning achievements. Taking the complexity of assessment and feedback for learning as a background, we have developed a new approach to the assessment for learning mathematics at university level. We devised mobile tablet technology supported assessment processes, and we carried out user studies in both Rwanda and Norway. Results of …

Design and Assessment of Optimized EMI Filters for Avionic Applications
2018
This paper presents a procedure to design EMI filters to reduce the electromagnetic disturbances generated by electrical apparatus used in avionic environment. The method proposed can be useful to save weight and size of the attenuation systems, and keep their effectiveness in agreement with the standard requirements. A design of a set of different filters with different topological characteristics is presented for a case study about an electrical actuator used for an aircraft onboard application. Performances and reliabilities of the attenuation systems are assessed by suitable full compliance experimental tests.
