Wesseldijk, Laura W.; Mosing, Miriam A.; Ullén, Fredrik – Developmental Psychology, 2019
Both genes and the environment are important for individual differences in expertise, but little is known about gene-environment interactions underlying domain-specific achievement. Here we explored this issue in a large Swedish twin cohort (N = 6,610), using moderator modeling with musical expertise as a model domain. Specifically, we tested…

Lundegård, Iann; Arvanitis, Leena; Hamza, Karim; Schenk, Linda; Wojcik, Andrzej; Haglund, Karin – Environmental Education Research, 2022
In the current debate, there is no consensus on the relationship between knowledge and values in students' reasoning and argumentation in socio-scientific and sustainability issues, i.e. if these should be addressed as separate entities or rather treated as a whole. In this study, we address this question empirically, with students engaging in two…

Zavala, Catalina; Beam, Christopher R.; Finch, Brian K.; Gatz, Margaret; Johnson, Wendy; Kremen, William S.; Neiderhiser, Jenae M.; Pedersen, Nancy L.; Reynolds, Chandra A. – Developmental Psychology, 2018
We examined whether attained socioeconomic status (SES) moderated genetic and environmental sources of individual differences in cognitive performance using pooled data from 9 adult twin studies. Prior work concerning SES moderation of cognitive performance has focused on rearing SES. The current adult sample of 12,196 individuals (aged 27-98…

Granbom, Martin – Journal of Biological Education, 2016
This study shows that formative methods and increased student participation has a positive influence on learning measured as grades. The study was conducted during the course Biology A in a Swedish Upper Secondary School. The students constructed grade criteria and defined working methods and type of examination within a given topic, Gene…

Nag, Heidi Elisabeth; Naerland, Terje – Journal of Intellectual Disabilities, 2021
Smith-Magenis syndrome (SMS) is a genetic syndrome most often caused by a deletion on chromosome 17 or more rarely by a mutation in the retinoic acid-induced 1 gene. The aim of this study was to investigate the Developmental Behavior Checklist (DBC) profile of persons with SMS and the associations between behavioural and emotional problems, age,…

Olson, Richard K.; Keenan, Janice M.; Byrne, Brian; Samuelsson, Stefan – Scientific Studies of Reading, 2014
Modern behavior-genetic studies of twins in the United States, Australia, Scandinavia, and the United Kingdom show that genes account for most of the variance in children's reading ability by the end of the 1st year of formal reading instruction. Strong genetic influence continues across the grades, though the relevant genes vary for reading words…

Thörne, Karin; Gericke, Niklas – Research in Science Education, 2014
This study investigates Swedish biology teachers' inclusion of proteins when teaching genetics in grade nine (students 15-16 years old). For some years, there has been a call to give attention to proteins when teaching genetics as a means of linking the concepts "gene" and "trait". Students are known to have problems with this…

Thörne, Karin; Gericke, Niklas M.; Hagberg, Mariana – Science Education, 2013
This study investigates Swedish teachers' use of language when teaching Mendelian genetics in compulsory school. The primary objective of the study is to explore how teachers use the related concepts "gene," "allele," and "anlag" (a Swedish variant of the German word "anlage") and how these are related to…

Marceau, Kristine; Horwitz, Briana N.; Narusyte, Jurgita; Ganiban, Jody M.; Spotts, Erica L.; Reiss, David; Neiderhiser, Jenae M. – Child Development, 2013
Studies of adolescent or parent-based twins suggest that gene-environment correlation (rGE) is an important mechanism underlying parent-adolescent relationships. However, information on how parents' and children's genes and environments influence correlated parent "and" child behaviors is needed to distinguish types of rGE. The present…

Isaksson, Johan; Taylor, Mark J.; Lundin, Karl; Neufeld, Janina; Bölte, Sven – Autism: The International Journal of Research and Practice, 2019
Alterations in social cognition are hypothesized to underlie social communication challenges in autism spectrum disorder. However, the etiologic underpinnings driving this association, as well as the impact of other psychiatric conditions on the association, remain unclear. Using a co-twin control design, we examined n = 308 twins (mean age =…

Lindahl, Mats Gunnar; Linder, Cedric – European Journal of Science and Mathematics Education, 2015
The conflicts between nature and nurture are brought to the fore and challenges socio-scientific decision-making in science education. The multitude of meanings of these concepts and their roles in societal discourses can impede students' development of understanding for different perspectives, e.g. on gene technology. This study problematizes…

Gericke, Niklas Markus; Hagberg, Mariana – Science & Education, 2010
This paper explores conceptual variation in the depiction of gene function in upper secondary school textbooks. Historically, concepts in genetics have developed in various scientific frameworks, which has led to a level of incommensurability as concepts have changed over time within their respective frameworks. Since students may have…

Peterson, Robin L.; Pennington, Bruce F.; Samuelsson, Stefan; Byrne, Brian; Olson, Richard K. – Journal of Speech, Language, and Hearing Research, 2013
Purpose: The goal of this study was to investigate the etiologic basis for the association between deficits in phonological memory (PM) and vocabulary in school-age children. Method: Children with deficits in PM or vocabulary were identified within the International Longitudinal Twin Study (ILTS; Samuelsson et al., 2005). The ILTS includes 1,045…

Lindahl, Mats Gunnar; Linder, Cedric – International Journal of Science Education, 2013
This paper reports on a study of how students' reasoning about socioscientific issues is framed by three dynamics: societal structures, agency and how trust and security issues are handled. Examples from gene technology were used as the forum for interviews with 13 Swedish high-school students (year 11, age 17-18). A grid based on modalities from…

Gericke, Niklas; Hagberg, Mariana; Jorde, Doris – Research in Science Education, 2013
In this study we investigate students' ability to discern conceptual variation and the use of multiple models in genetics when reading content-specific excerpts from biology textbooks. Using the history and philosophy of science as our reference, we were able to develop a research instrument allowing students themselves to investigate the…
