Essays concerning Hume's natural philosophy
2016
The subject of this essay-based dissertation is Hume’s natural philosophy. The dissertation consists of four separate essays and an introduction. These essays do not only treat Hume’s views on the topic of natural philosophy, but his views are placed into a broader context of history of philosophy and science, physics in particular. The introductory section outlines the historical context, shows how the individual essays are connected, expounds what kind of research methodology has been used, and encapsulates the research contributions of the essays. The first essay treats Newton’s experimentalist methodology in gravity research and its relation to Hume’s causal philosophy. It is argued tha…
Las Leyes de Newton de la mecánica: Una revisión histórica y sus implicaciones en los textos de enseñanza
2013
Este trabajo destaca la importancia de una presentación coherente y actualizada de la dinámica clásica como un factor clave para su aprendizaje. La primera parte de este trabajo contiene un análisis histórico de los aspectos críticos de las leyes de la dinámica clásica que muestra sus ambigüedades y sus posibles interpretaciones. A continuación, se analizan las alternativas de enseñanza en algunos libros de texto haciendo especial énfasis en sus características fundamentales. Como resultado, se concluye que la presentación de la dinámica clásica, tal como se hace actualmente, muestra deficiencias tanto de coherencia como de actualización, lo que sugiere la necesidad de una revisión general …
Does using a visual-representation tool foster students’ ability to identify forces and construct free-body diagrams?
2013
Earlier research has shown that after physics instruction, many students have difficulties with the force concept, and with constructing free-body diagrams (FBDs). It has been suggested that treating forces as interactions could help students to identify forces as well as to construct the correct FBDs. While there is evidence that identifying interactions helps students in quantitative problem solving, there is no previous research investigating the effect of a visual-representation tool—an interaction diagram (ID)—on students’ ability to identify forces, and to construct the correct FBDs.We present an empirical study conducted in 11 Finnish high schools on students (n ¼ 335, aged 16) takin…
