In this article, we describe the main phases in the development and validation of a questionnaire measuring secondary students' teleology and essentialism conceptions in the context of genetics. The validation process involved 714 Swiss and French secondary school students from 14 different schools. The process included interviews, several pilot…

This article provides an assessment of French media coverage of intelligence research. The analysis is based on articles published between 1992 and 2020 in French nationwide newspapers, local newspapers and science magazines. Two themes regularly appear in nationwide newspapers and science magazines: environmental effects on IQ and animal…

Background: Rubinstein-Taybi syndrome (RSTS) is a multiple congenital anomaly syndrome characterised by several typical somatic characteristics and by developmental disabilities with various degrees of severity. Focusing on children with RSTS, the aim of this study was to describe their psychomotor, cognitive, and socio-emotional developmental…

Purpose: Multiple factors impact reading acquisition in individuals with reading disability, including genetic disorders such as Williams syndrome (WS). Despite a relative strength in oral language, individuals with WS usually have an intellectual disability and tend to display deficits in areas associated with reading. There is substantial…

Innatism is the belief that most of the human personality can be determined by genes. This ideology is dangerous, especially when it claims to be scientific. The present study investigates conceptions of 1060 students from Estonia and France related to genetic determinism of some human behaviours. Factors taken into account included students'…

Background: Studies conducted on mild intellectual disability (MID) in children are infrequent and the prevalence rates vary widely. This study aimed to estimate the prevalence of MID in children in a French county (Isère), to describe the clinical signs and associated comorbidities, and to specify the aetiologies of this disability. Methods: The…

The presentation of genetic diseases in French secondary school biology textbooks is analysed to determine the major conceptions taught in the field of human genetics. References to genetic diseases, and the processes by which they are explained (monogeny, polygeny, chromosomal anomaly and environmental influence) are studied in recent French…

We tried to determine the reasoning behind the stances taken by a group of 19-21-year-old students on the controversial issue of the feasibility and acceptability of human gene therapy. The students were in training at a biotechnology institute. We organised classroom debates, punctuated by phases of epistemological "disturbances". We…

We have been teaching applied molecular genetics to engineers and adapted the teaching methodology to the European Credit Transfer System. We teach core principles of genetics that are universal and form the conceptual basis of most molecular technologies. The course then teaches widely used techniques and finally shows how different techniques…

The Strasbourg University PhD school in Life and Health Sciences launched an initiative called "OpenLAB." This project was developed in an effort to help high school teenagers understand theoretical and abstract concepts in genetics. A second objective of this program is to help students in defining their future orientation and to…

Introduction: The present study reports cross-cultural comparisons of body mass index (BMI) and growth in Prader-Willi syndrome, a neurodevelopmental disorder associated with obesity, growth restriction and mild learning disability. Our objectives were to: (1) compare rates of obesity in adults with Prader-Willi syndrome (PWS) in France, with data…

The role of hypovitaminosis D as a possible risk factor for multiple sclerosis is reviewed. First, it is emphasized that hypovitaminosis D could be only one of the risk factors for multiple sclerosis and that numerous other environmental and genetic risk factors appear to interact and combine to trigger the disease. Secondly, the classical…

"Biological identity" is the result of interactions between the environment and the genome. These interactions, however, were not taught before 2001. In the French syllabus for 16-year-old students, two of the five sections on genetics deal with biological identity. We analysed the texts and images of the chapters relating to these two…

Background: Prader-Willi syndrome (PWS) is a rare genetic disorder characterised by developmental abnormalities leading to somatic and psychological symptoms. These include dysmorphic features, impaired growth and sexual maturation, hyperphagia, intellectual delay, learning disabilities and maladaptive behaviours. PWS is caused by a lack of…

An international team that includes researchers from the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health (NIH), has discovered that mammalian chromosomes have evolved by breaking at specific sites rather than randomly as long thought--and that many of the breakage hot spots are also involved in human…
