The Challenges of Learning and Teaching Chemical Bonding at Different School Levels Using Electrostatic Interactions Instead of the Octet Rule as a Teaching Model
Peer reviewed Peer reviewed
Direct linkDirect link
Joki, Jarkko; Aksela, Maija – Chemistry Education Research and Practice, 2018
Teaching chemical bonding using the octet rule as an explanatory principle is problematic in many ways. The aim of this case study is to understand the learning and teaching of chemical bonding using a research-informed teaching model in which chemical bonding is introduced as an electrostatic phenomenon. The study posed two main questions: (i)…

Affeldt, Fiona; Tolppanen, Sakari; Aksela, Maija; Eilks, Ingo – Chemistry Education Research and Practice, 2017
Non-formal education has been suggested as becoming more and more important in the last decades. As the aims of non-formal education are broad and diverse, a large variety of non-formal learning activities is available. One of the emerging fields in many countries, among them Finland and Germany, has been the establishment of non-formal laboratory…

Coulombic Interaction in Finnish Middle School Chemistry: A Systemic Perspective on Students' Conceptual Structure of Chemical Bonding
Peer reviewed Peer reviewed
Direct linkDirect link
Joki, Jarkko; Lavonen, Jari; Juuti, Kalle; Aksela, Maija – Chemistry Education Research and Practice, 2015
The aim of this study was to design a novel and holistic way to teach chemical bonding at the middle school level according to research on the teaching and learning of bonding. A further aim was to investigate high achieving middle school students' conceptual structures concerning chemical bonding by using a systemic perspective. Students in one…

A Novel Course of Chemistry as a Scientific Discipline: How Do Prospective Teachers Perceive Nature of Chemistry through Visits to Research Groups?
Peer reviewed Peer reviewed
Direct linkDirect link
Vesterinen, Veli-Matti; Aksela, Maija – Chemistry Education Research and Practice, 2009
To achieve sufficient pedagogical content knowledge on nature of chemistry related issues, teachers need structured opportunities for reflection and discussion. One way to provide those opportunities is through teacher-scientist interaction. This study is based on reflective essays of thirty prospective teachers who participated in a new course…

Peer reviewed Peer reviewed
Direct linkDirect link
Aksela, Maija; Lundell, Jan – Chemistry Education Research and Practice, 2008
Modern computer-based molecular modelling opens up new possibilities for chemistry teaching at different levels. This article presents a case study seeking insight into Finnish school teachers' use of computer-based molecular modelling in teaching chemistry, into the different working and teaching methods used, and their opinions about necessary…
