Abstract Previous research showed students faced difficulties in solving the given problems in the Abstract Algebra course. The research aimed to describe the effect of the method of problem-based learning integrated with videos and worksheets to improve the proving skills of mathematics education students in one of the universities in Central Kalimantan, Indonesia. The researcher developed and uploaded the videos on YouTube. The research design was an experimental study. The researcher implemented the method in an experimental class. The control class students learned by using the usual method of the past three years that emphasized acquiring the Abstract Algebra concepts. The researcher selected the experimental class randomly. The numbers of students in the experimental and control classes were 32 and 28, respectively. The students of both classes solved the same problems in the post-test at end of the implementation. The post-test contained five problems to prove. The research results showed that the transactive reasoning activities in the experimental class enabled the students to prove at an appropriate abstraction level. The students’ scores in the Abstract Algebra for the experimental class were greater than those in the control class. Therefore, the method affected students’ ability to solve Abstract Algebra problems.

Introducción. En el contexto educativo, las tecnologías de la información y la comunicación (TIC) implican un cambio de paradigma en los procesos de enseñanza-aprendizaje, tanto en la renovación de las prácticas y contenidos, como en la manera de evaluar la apropiación de los conocimientos. En este sentido, en la presente investigación se analiza la incidencia que tiene la implementación de las estrategias didácticas, Aprendizaje Basado en Problemas (ABP) y Aprendizaje Colaborativo (AC) en el fortalecimiento de los niveles de razonamiento, a través de la integración de la tecnología a la educación superior.Método. La investigación presenta enfoque cuantitativo, con diseño cuasiexperimental en la cual participaron 35 estudiantes de la Universidad Colegio Mayor de Cundinamarca en Bogotá - Colombia, a quienes se les aplicó un pre y un post test, usando el Lawson´s Classroom Test of Scientific ReasoningResultados. Con la información obtenida y al realizar un análisis estadístico descriptivo es posible afirmar que un 85.29% del total de estudiantes aún se encuentran en el nivel de razonamiento concreto, sin embargo aquellos estudiantes que participaron en la estrategia didáctica de ABP presentaron una mejora en su nivel de razonamiento, pasando del nivel de razonamiento concreto al nivel formal y post-formal.Conclusiones. Los resultados obtenidos permiten concluir que no existe una diferencia estadísticamente significativa en la mejora de las habilidades de razonamiento antes y después de la aplicación de las estrategias didácticas, ya que al comparar el razonamiento de los estudiantes se evidencia que en su mayoría aún se encuentran en el nivel de razonamiento concreto, es decir, que permanecen ligados a una realidad empírica con un pensamiento pre-operacional.

Abstract: Introduction: According to the European Centre for Disease Prevention and Control, the prevalence of neuroinvasive symptoms caused by the West Nile virus (WNV) has significantly increased in the past years throughout Europe, including Hungary. The rise may be attributed to changes in precipitation and climate. The WNV zoonosis is spread by mosquitoes. It is mostly asymptomatic, flu-like symptoms occur in 20% of the cases and in less than 1% a neuroinvasive disease with a lethal outcome may develop. Aim: Our aim was to demonstrate the neuroinvasive symptomatology and the diagnosis and treatment of WNV infections by describing our patient cases as well as to resolve differential diagnostic dilemmas. Method: We report the cases of 4 patients treated at the “Moritz Kaposi” Somogy County Hospital between the 31st July and 4th September, 2018, with WNV, whose diagnoses were confirmed by serological and molecular biological methods. An epidemiological overview of WNV infections was also given. Results: Four patients were confirmed to have had WNV infection in the given time period. A wide range of neurological symptoms were observed in each patient and death occurred in one case. The patients were elderly with a number of comorbidities. Conclusions: The appearance of more severe, neuroinvasive symptoms following WNV infections is also characteristic of Hungary. The treatment of the infection is supportive, including giving pain relievers and the management of secondary infections. It is important to consider the possibility of a WNV infection in the case of a neurological disease of unknown origin, particularly if the symptoms indicate encephalitis.
