Abstract [en]

There is an abundance of dynamic visualizations (animations, videos and simulations) that claim to explain evolution available on the Internet. The present study explores what aspects of evolution that are represented in these potential learning tools. A criteria catalogue covering 40 operationalized variables was used as a content analysis grid in the analysis of 71 dynamic visualizations. The concepts, derived from research literature, were operationalized into variables sorted into four different categories: (a) content-specific concepts (such as limited resources or inherited variation), (b) threshold concepts (core concepts that transform and integrate understanding within a subject), (c) alternative conceptions (such as teleological explanations or anthropomorphism), and (d) model organism. The results indicate that some concepts are dominantly communicated while others are seldom or never included in online visualizations. Regarding the proposed threshold concepts, evolutionary events happening on small time- and spatial scales, such as subcellular processes, were seldom observed. Rather, the focus was on events happening at a population level in time scales spanning from years and longer. This echoes with an observed lack of explanations regarding randomly occurring mutations providing the basis for variation. Implications include that there are components of evolution that would benefit from being addressed with an increased focus in biology teaching and science education research. The results may also serve as a useful toolkit in the design of new educational material.

Abstract [en]

Machine metaphors are ubiquitous in the molecular sciences. In addition to their use by scientists, educators and popularizers of science, they have been promoted intensively by the Intelligent Design (ID) movement in arguments for the necessity of a god-like designer to account for the complexities of life at the molecular level. The authors have investigated the visual rhetoric employed in a movie by ID proponents, with particular emphasis on machine metaphors. The authors provide examples and argue that science communicators could reduce the persuasive impact of ID visual rhetoric based on machine metaphors by emphasizing that self-assembly is fundamental to molecular complexes.

Abstract [en]

The present study explores the extent and precision of evolutionary explanations for antibiotic resistance in communication directed toward the Swedish public. Bacterial resistance develops through evolutionary mechanisms and knowledge of these helps to explain causes underlying the growing prevalence of resistant strains, as well as important countermeasures to address the problem. A content analysis based on key evolutionary concepts underpinning resistance development was conducted on three different data sources: print newspapers, online websites and biology textbooks. The results revealed that evolutionary mechanisms are seldom included in accounts of antibiotic resistance provided by these sources. One of the included textbooks (n = 6) but none of the newspaper articles (n = 221) or websites (n = 19) covered all six concepts considered in the analysis. A cluster of four concepts regarded as most important for understanding the evolution of resistance development was only included in one news article, one textbook and two websites. Moreover, explanations were seldom supported visually and only two accompanying illustrations were found during the analysis. The results indicated that a large proportion of the Swedish public might never encounter an explanation of antibiotic resistance in evolutionary terms. This could be problematic since increased public awareness and understanding is crucial to counter the issue of bacterial resistance.

Abstract [en]

Despite its recognized importance, the theory of evolution presents severe problems to learners. A common approach in science education research involves the division of evolution in conceptual constructs, lately also including the role of threshold concepts. These are seminal ideas that open up new ways of thinking about and interpreting previously known processes. For understanding of evolution, threshold concepts consist of, for example, randomness, probability and wide-stretched spatio-temporal scales. An abundance of dynamic visualizations (animations, videos and simulations), attempting to explain evolution, are available on the Internet. The aim with our study was to map what aspects of evolution that are represented in these visualizations. A criteria catalogue covering 42 operationalized variables was used as a content analysis grid in the analysis of a sample selection including 71 dynamic visualizations. The variables include evolution content concepts (such as limited resources and differential survival) and proposed threshold concepts (such as explicit mentioning of factors influenced by randomness or level of organization in space and time, including connections between submicro- and macro aspects). Furthermore, it includes common alternative conceptions (such as anthropomorphism or that evolution is driven by need). Two raters conducted the analysis with an overlapping reliability sample covering 23 visualizations. Intercoder reliability was calculated using Krippendorff’s alpha. The results indicate that some concepts are dominantly communicated while others are seldom or never included in online visualizations. Regarding the proposed threshold concepts, evolutionary events happening on small time- and spatial scales, such as subcellular processes, were seldom observed. Rather, the focus was on events happening at a population level in time scales spanning from years and longer. Implications include that there are components of evolution that would benefit from being addressed more explicit. The results may also serve as a useful toolkit in the design of new educational material.

Abstract [en]

Antibiotic resistance is an increasing global threat involving many actors, including the general public. We present findings from a content analysis of the coverage of antibiotic resistance in the Swedish print media with respect to the risk communication factors cause, magnitude and countermeasures. The most commonly reported cause of development and spread of resistance was unnecessary prescription of antibiotics. Risk magnitudes were mostly reported qualitatively rather than using quantitative figures. Risk-reduction measures were analyzed using a framework that distinguishes between personal and societal efficacy. Measures at the societal level were more commonly reported compared to the individual level.

Abstract [sv]

Att DNA är bärare av de ärftliga anlagen visades första gången 1944 i en studie ledd av Oswald T. Avery. Generna ansågs på denna tid bäras av proteiner och det tog tid innan resultaten accepterades. Övergången till ett erkännande av DNA som bärare av genetisk information kan liknas vid ett paradigmskifte, som skedde ungefär tio år senare.

Föreliggande arbete baseras i huvudsak på intervjuer med svenska forskare som var aktiva inom nukleinsyreforskning från 1950 och framåt. Syftet med studien var att komplettera och fördjupa bilderna som existerar av skeendena och tidsperspektiven kring paradigmskiftet, med särskilt fokus på hur det tog sig uttryck i Sverige. Därtill diskuteras, utifrån olika perspektiv, tänkbara förklaringar till att Avery aldrig belönades med Nobelpriset för sin upptäckt. Resultaten tyder på att debatten om vilken molekyl som bär arvsanlagen framförallt ägde rum i USA. Den var inte lika framträdande i Sverige och skiftet skedde troligen något senare här. En viktig förklaring står sannolikt att finna i organisationen kring den nationella nukleinsyreforskningen. Förklaringar till Averys uteblivna Nobelpris diskuteras i form av enskilda aktörer, organisationsfaktorer och mer övergripande strukturer.

Abstract [en]

The first evidence of DNA as the carrier of genetic information was published in 1944 in a study led by Oswald T. Avery. This task had previously been attributed to proteins and the results were not immediately accepted. The transition to an acceptance of DNA as the carrier of genetic information has been likened to a paradigm shift which occurred about ten years later.

This project is mainly based on interviews with Swedish scientists who were active in nucleic acid research from 1950 and onwards. The aim of the present study was to deepen and discuss the available knowledge concerning time and events of the paradigm shift in Sweden. Moreover, possible reasons for Avery not being awarded the Nobel Prize are discussed from different aspects. The results indicate that the debate on which molecule carries the genes mainly took place in USA. It was not as prominent in Sweden and the acceptance probably happened somewhat later there. That is likely to be explained by the organisation of the national nucleic acid research. Explanations as to why Avery was not awarded a Nobel Prize are discussed in the form of individuals, organisational factors as well as in overall structures.
