Visualizing Solubilization by a Realistic Particle Model in Chemistry Education

2019

An application for the visualization of the mixing process of two different types of structureless interacting particles is presented. The application allows to demonstrate on a qualitative basis, as well as by quantitatively monitoring the time evolution of the fractions of aggregates of different sizes, that the formation of a homogeneous mixture is the result of favorable solute-solvent interactions as well as by temperature. It is suggested that, along with the use of suitable macroscopic examples, visualizations by the present application are useful in elucidating concepts related to miscibility/solubility. The application is based on a two-dimensional realistic dynamic model where ato…

Workshop: iPads in Upper Secondary School Chemistry Education

2014

At the workshop arranged at the National Days of Chemical Education the participants had an opportunity to try out various Ipad apps and methods for utilizing them in chemistry education. The themes were based on the apps used during chemistry teacher education course arranged by the department of chemistry and methods developed on the teacher training school at the University of Jyväskylä. The apps used included Socrative Student, Google Drive, Graphical Analysis, ChemDoodle ja QR-reader. Out of these Socratice, which collects students answers to questions created by the teacher, was considered easy-to-use and the most useful by the participants. The participants also felt, that the worksh…

Kitchen chemistry course for chemistry education students: influences on chemistry teaching and teacher education – a multiple case study

2019

AbstractThis study introduces the Kitchen Chemistry (KC) course and its influences on chemistry education as a whole. KC is considered to be a life-relevant learning environment that engages learners in science through the pursuit of personally relevant and meaningful goals. KC, as a form of interdisciplinary learning, aims to develop boundary-crossing skills and to support the development of pupils’ scientific thinking. The purpose of this research was to determine how KC as a context-based teaching approach applies to chemistry education and what it offers to chemistry teaching and teacher education. We found that KC gave lower secondary school pupils the opportunity to understand the che…

Upper Secondary School and University Level Students’ Perceptions of Extractions in Context: Experiences from a Simple Laboratory Experiment

2021

We discuss the pedagogical challenges associated with the current way of introducing extraction in upper secondary school chemistry education. These challenges were identified based on a survey of upper secondary school textbooks and verified through a questionnaire study. To address the identified challenges, we introduce a simple and effective extraction experiment which focuses on building a deeper conceptual understanding of extraction processes. The operationally simple extraction experiment and the accompanying questionnaire revealed that while students have several chemical misconceptions arising from the use of superficial everyday examples, they have all the necessary knowledge for…

Modeller i kjemiundervisning - et eksempel på hvordan de kan bidra til læring og feillæring

2021

We discuss the use of analogical models in science education using examples from online learning resources.  We have conducted a teaching program for a group of 7th grade pupils and a group of science teacher students, and the main theme of this program is the use of models in chemistry. Specifically, we study the effect of an analogical model that is designed to promote understanding of the properties of molecules, related to a paper chromatography experiment. Our research indicates that analogical models can be a useful tool to convey understanding of abstract concepts and non-visible phenomena, but they hold serious pitfalls that can lead to misunderstandings amongst students if not used…

Ciencia de la sostenibilidad: un nuevo campo de conocimientos al que la química y la educación química están contribuyendo

2013

Los dominios de conocimiento más diversos contribuyen actualmente al tratamiento de problemas socioambientales. Se han publicado muchos artículos y libros en los campos de Química Verde, Ecología Industrial, Ingeniería Ambiental, Economía Verde (baja en carbono), Educación Ambiental, etc. Pero hace poco se entendió que estas contribuciones son insuficientes y que necesitamos una Ciencia de Sostenibilidad que los integra a todos. Este documento estudia el surgimiento de este nuevo campo de conocimiento e investigación, cuyo objetivo explícito es contribuir a la transición a una sociedad sostenible. The most diverse knowledge domains are currently contributing to the treatment of socio-enviro…

Reflections on the Nature of the Periodic Table of the Elements: Implications in Chemical Education

2014

The periodic table of the elements (PTE) results essential to understand our nature and place in the whole of beings. The same happens with our food, drugs, materials, etc. A series of questions were asked to introduce PTE and provide answers. The ideas in PTE should be valued by the number of questions that they generate. The PTE was related to electron configurations. The emergence of elements (nucleosynthesis) in physics was explained. The PTE results essential to understand our nature and place in the whole of beings. The same happens with our food, drugs, materials, etc. Schwarz and Rich asked a series of questions (Qs) to introduce PTE and provided answers. The ideas on PTE should be …

Mapping the Teaching of History of Chemistry in Europe

2016

Recent developments in the field of history of chemistry have introduced new topics, challenges, and connections to a broad range of scientific, political, cultural, economic, and environmental issues. New audiences for the history of chemistry have emerged along with new topics, protagonists, spaces, and historical narratives. This paper summarizes the main results of a recent survey to map the current situation of the teaching of history of chemistry in Europe. We review how and where history of chemistry is taught in Europe, considering not only graduate students in science programs, but also other audiences such as science teachers, and the general public. This paper also provides updat…
