Comprensión de la teoría especial de la relatividad y diseño de una visita guiada a un museo de ciencia
2007
SUMMARY The problem which we are tackling in this work emerges from three different concerns: the importance of `learning science `informally¿ as part of the school curriculum, the need for scientific literacy and the importance of the social implications of contemporary science. An exhibition was used in the Kutxaespacio Science Museum in San Sebastian on the centenary of the Spatial Theory of Relativity to design a visit for first year Engineering students and assess the learning which is achieved. The first part of the work presents the design which was produced to build bridges between formal teaching and the exhibition visit. The second part analyses the potential of the exhibition and…
A Cognitive model to analyse physics and chemistry problem-solving skills: mental representations implied in solving actions
2020
In physics and chemistry, the development of problem-solving skills is necessary to become an expert. A simple cognitive model to analyse such development is proposed and tested. An exploratory research was conducted with expert professors and students in initial and advanced years. A think aloud procedure was used to obtain relevant data while the participants tried to solve undefined, open problems. Solving these problems required a particular skill representative of expertise: modelling reality using science. More than 1350 solving actions were collected and related to the mental representations elaborated, developed and inter-related by solvers. The proposed model was able to account fo…
Testing a model for the monitoring of worked-out algebra-problem examples: from behaviours to outcomes on a math task
2021
This study aimed at testing an extension of a theoretical model for the metacognitive monitoring mechanism implied in the detection of inconsistencies when the information provided includes abstract symbols in addition to plain text. Ninety-four postgraduates of STEM specialities were asked to read a worked-out algebra-problem example and to report any incoherence, inconsistency, or error detected in the statement or in the solving procedure. A set of model inspired indexes was defined to describe participants¿ behaviour along the task. The Read & Answer software was used to record online individual processing data and participants¿ reports. Results supported model predictions. Indexes corr…
La historia del primer principio de la termodinámica y sus implicaciones didácticas
2007
En este trabajo se realiza una breve introduccion historica y epistemologica del nacimiento de la termodinamica como ciencia moderna. Se muestra, asi mismo, como esta historia puede contribuir a mejorar la ensenanza de la termodinamica y a superar algunas dificultades de los estudiantes.Palabras Clave: historia de la ciencia; ensenanza y aprendizaje de la termodinamicaThe history of the first law of thermodynamics and its didactict implicationsIn this work is carried out a brief historical and epistemological introduction of the thermodynamics’ birth as a modern science. It is shown, likewise, how this history can contribute to improve the teaching of thermodynamics and to overcome some stu…
