Stern, Florian; Kampourakis, Kostas; Müller, Andreas – Journal of Research in Science Teaching, 2023
Biology education research has shown that deeply rooted intuitions can influence students' understanding of biological phenomena. One example is design teleology, the intuition that organisms' traits were designed to fulfill a goal. Another example is psychological essentialism, the intuition that organisms have fixed essences. Past research has…

Castro-Faix, Moraima; Duncan, Ravit Golan; Choi, Jinnie – Journal of Research in Science Teaching, 2021
Learning progressions are theoretical models that describe learning of scientific ideas and practices over time. These hypothetical progressions need to be tested and refined in order to productively inform instruction and assessment. In this paper, we report our attempts to revise a learning progression in genetics. In particular, we focused on…

Donovan, Brian M.; Weindling, Monica; Salazar, Brae; Duncan, Alex; Stuhlsatz, Molly; Keck, Phillip – Journal of Research in Science Teaching, 2021
Recently, it has been argued that improving students' genomics literacy could prevent students from developing erroneous beliefs about social identity, such as the belief that racial groups differ cognitively and behaviorally because of their genes; a belief called genetic essentialism. To date, however, little research has explored if or how a…

Haskel-Ittah, Michal; Duncan, Ravit Golan; Vázquez-Ben, Lucia; Yarden, Anat – Journal of Research in Science Teaching, 2020
Mechanisms are central in scientific explanations. However, developing mechanistic explanations is difficult for students especially in domains in which mechanisms involve abstract components and functions, such as genetics. One of the core components of genetic mechanisms are proteins and their functions. Students struggle to reason about the…

Premo, Joshua; Cavagnetto, Andy; Honke, Garrett; Kurtz, Kenneth J. – Journal of Research in Science Teaching, 2019
The idea that characteristics acquired by an organism during its lifetime can be inherited by offspring and result in evolution is a substantial impediment to student understanding of evolution. In the current study, we performed a preliminary examination of how acquiring physical changes in a question prompt may differentially cue intuitive and…

Todd, Amber; Kenyon, Lisa – Journal of Research in Science Teaching, 2016
This article describes revisions to four of the eight constructs of the Duncan molecular genetics learning progression [Duncan, Rogat, & Yarden, (2009)]. As learning progressions remain hypothetical models until validated by multiple rounds of empirical studies, these revisions are an important step toward validating the progression. Our…

Horn, Michael S.; Phillips, Brenda C.; Evans, Evelyn Margaret; Block, Florian; Diamond, Judy; Shen, Chia – Journal of Research in Science Teaching, 2016
In this study, we investigate museum visitor learning and engagement at an interactive visualization of an evolutionary tree of life consisting of over 70,000 species. The study was conducted at two natural history museums where visitors collaboratively explored the tree of life using direct touch gestures on a multi-touch tabletop display. In the…

Dauer, Joseph T.; Long, Tammy M. – Journal of Research in Science Teaching, 2015
One of the goals of college-level introductory biology is to establish a foundation of knowledge and skills that can be built upon throughout a biology curriculum. In a reformed introductory biology course, we used iterative model construction as a pedagogical tool to promote students' understanding about conceptual connections, particularly those…

Dauer, Joseph T.; Momsen, Jennifer L.; Speth, Elena Bray; Makohon-Moore, Sasha C.; Long, Tammy M. – Journal of Research in Science Teaching, 2013
Research in contemporary biology has become increasingly complex and organized around understanding biological processes in the context of systems. To better reflect the ways of thinking required for learning about systems, we developed and implemented a pedagogical approach using box-and-arrow models (similar to concept maps) as a foundational…

Waight, Noemi; Abd-El-Khalick, Fouad – Journal of Research in Science Teaching, 2011
The Biology Workbench (BW) is a web-based tool enabling scientists to search a wide array of protein and nucleic acid sequence databases with integrated access to a variety of analysis and modeling tools. The present study examined the development of this scientific tool and its consequent adoption into the context of high school science teaching…

Venville, Grady J.; Dawson, Vaille M. – Journal of Research in Science Teaching, 2010
The literature provides confounding information with regard to questions about whether students in high school can engage in meaningful argumentation about socio-scientific issues and whether this process improves their conceptual understanding of science. The purpose of this research was to explore the impact of classroom-based argumentation on…

Duncan, Ravit Golan; Reiser, Brian J. – Journal of Research in Science Teaching, 2007
In this article we apply a novel analytical framework to explore students' difficulties in understanding molecular genetics--a domain that is particularly challenging to learn. Our analytical framework posits that reasoning in molecular genetics entails mapping across ontologically distinct levels--an information level containing the genetic…

Cavallo, Ann M. L. – Journal of Research in Science Teaching, 1996
Explores relationships among school students' (n=189) meaningful learning orientation, reasoning ability and acquisition of meaningful understandings of genetics topics, and ability to solve genetics problems. Results indicate that meaningful learning orientation best predicted students' understanding of genetics interrelationships while reasoning…

Smith, Mike U. – Journal of Research in Science Teaching, 1991
Criticizes an article by Browning and Lehman (1988) for (1) using "gene" instead of allele, (2) misusing the word "misconception," and (3) the possible influences of the computer environment on the results of the study. (PR)

Browning, Mark; Lehman, James D. – Journal of Research in Science Teaching, 1991
Authors respond to criticisms by Smith in the same issue and defend their use of the term "gene" and "misconception." Authors indicate that they did not believe that the use of computers significantly skewed their data concerning student errors. (PR)
