Characterisation of the Context-Dependence of the Gene Concept in Research Articles: Possible Consequences for Teaching Concepts with Multiple Meanings
Peer reviewed Peer reviewed
Direct linkDirect link
Flodin, Veronica S. – Science & Education, 2017
The purpose of this study is to interpret and qualitatively characterise the content in some research articles and evaluate cases of possible difference in meanings of the gene concept used. Using a reformulation of Hirst's criteria of forms of knowledge, articles from five different sub-disciplines in biology (transmission genetic, molecular…

van Mil, Marc H. W.; Boerwinkel, Dirk Jan; Waarlo, Arend Jan – Science & Education, 2013
Although molecular-level details are part of the upper-secondary biology curriculum in most countries, many studies report that students fail to connect molecular knowledge to phenomena at the level of cells, organs and organisms. Recent studies suggest that students lack a framework to reason about complex systems to make this connection. In this…

The Allusion of the Gene: Misunderstandings of the Concepts Heredity and Gene
Peer reviewed Peer reviewed
Direct linkDirect link
Falk, Raphael – Science & Education, 2014
Life sciences became Biology, a formal scientific discipline, at the turn of the nineteenth century, when it adopted the methods of reductive physics and chemistry. Mendel's hypothesis of inheritance of discrete factors further introduced a quantitative reductionist dimension into biology. In 1910 Johannsen differentiated between the…

Conceptual Variation or Incoherence? Textbook Discourse on Genes in Six Countries
Peer reviewed Peer reviewed
Direct linkDirect link
Gericke, Niklas M.; Hagberg, Mariana; dos Santos, Vanessa Carvalho; Joaquim, Leyla Mariane; El-Hani, Charbel N. – Science & Education, 2014
The aim of this paper is to investigate in a systematic and comparative way previous results of independent studies on the treatment of genes and gene function in high school textbooks from six different countries. We analyze how the conceptual variation within the scientific domain of Genetics regarding gene function models and gene concepts is…

Mendel in the Modern Classroom
Peer reviewed Peer reviewed
Direct linkDirect link
Smith, Mike U.; Gericke, Niklas M. – Science & Education, 2015
Mendel is an icon in the history of genetics and part of our common culture and modern biology instruction. The aim of this paper is to summarize the place of Mendel in the modern biology classroom. In the present article we will identify key issues that make Mendel relevant in the classroom today. First, we recount some of the historical…
