Adopting the Discovery Method to Develop Linguistic Competence Among International Students: Experience from Russia and Belarus

The article addresses linguistic competence and the importance of its formation for academic and professional purposes. It also posits that linguistic competence is an important part of the communicative one. The Discovery Method is proposed as a privileged tool when teaching international students to apply the norms and rules established in a language. In this article the authors give a number of reasons why this method should be used, and how to apply it during English teaching process in a class. The research is based on the data collected during English and Russian classes and is conducted in three universities by means of observation, discussion, interview, and questionnaire. The article proposes a set of 3 tables of descriptors to assess the student’s linguistic competence in three types of class activities: translation, writing, and reading. It also introduces a framework of exercises for teachers who wish to use the Discovery Method. Theoretical ground has been set for further research, focusing on the results of using the Discovery Method for linguistic competence formation

Supporting citizen inquiry: an investigation of Moon rock

Citizen inquiry is an innovative way for non-professionals to engage in practical scientific activities, in which they take the role of self-regulated scientists in informal learning contexts. This type of activity has similarities to inquiry-based learning and to citizen science, but also important differences. To understand the challenges of supporting citizen inquiry, a prototype system and activity has been developed: the Moon Rock Explorer. Based on the nQuire Toolkit, this offers people without geology expertise an open investigation into authentic specimens of Moon rock, using a Virtual Microscope. The Moon Rock Explorer inquiry has been evaluated in an informal learning context with PhD students from the Open University. Results of the evaluation raise issues related to motivation and interaction between inquiry participants. They also provide evidence that the integration of scientific tools was successful and that the nQuire Toolkit is suitable to deploy and enact citizen inquiries

Aula virtual CristoAct para mejorar la actitud de los estudiantes frente a la asignatura de cristología en la Universidad Católica Santo Toribio de Mogrovejo, Chiclayo 2014

La investigación surge como respuesta a la preocupación por las actitudes de rechazo y desinterés de los estudiantes frente a las asignaturas de teología, específicamente cristología; así mismo a la exigencia de la incorporación de la tecnología de la información y comunicación (TIC) en el proceso de enseñanza aprendizaje, potenciando así, la construcción del aprendizaje. Se propone la implementación del aula CristoAct, en la plataforma Moodle, como medio de apoyo a las sesiones presenciales de la asignatura de cristología; teniendo como objetivo demostrar que el uso del aula virtual CristoAct, mejora la actitud de los estudiantes frente a la asignatura de cristología de la Universidad Católica Santo Toribio de Mogrovejo. La metodología aplicada fue de tipo experimental, con diseño cuasi experimental de un sólo grupo, con pretest y postest. Teniendo como población, estudiantes matriculados en la asignatura de cristología distribuidos en 7 secciones; y como muestra a los estudiantes de la sección “G”. El grupo en estudio mejoró el nivel de actitud frente a la asignatura de cristología demostrando que la utilización del aula CristoAct ha facilitado espacios para compartir, interactuar y realizar la extensión de la temática en estudio, reflejándose los resultados en su rendimiento académico. La actitud positiva de los estudiantes se debió al uso del entorno virtual como elemento didáctico, ya que motivó a los estudiantes y acrecentó una actitud favorable frente a la asignatura; siendo reutilizables los recursos multimedia diseñados e implementados por el autor en cualquier plataforma y/o servidores de la web.Tesi

Graphical means for inspecting qualitative models of system behaviour

This article presents the design and evaluation of a tool for inspecting conceptual models of system behaviour. The basis for this research is the Garp framework for qualitative simulation. This framework includes modelling primitives, such as entities, quantities and causal dependencies, which are combined into model fragments and scenarios. Given a library of model fragments and a scenario describing an initial situation, the qualitative simulation engine generates predictions in the form of a state-transition graph. This rich knowledge representation has potential for educational purposes. However, communicating the contents of simulation models effectively to learners is not trivial. The predicate logic format used by Garp is not easy for non-experts to understand, and a simulation often contains so much information that it is difficult to get an overview while still having access to detailed information. To address these problems, a tool has been developed that generates graphical representations of the information contained in a qualitative simulation. This tool, named VisiGarp, incorporates a vocabulary of graphical elements for model ingredients and relationships, and combines these into interactive diagrams. VisiGarp has been evaluated by thirty students, with promising results, using a setup which included simulation results and exercises about Brazilian Cerrado ecology
