Stuhlsatz, Molly A. M.; Buck Bracey, Zoë E.; Donovan, Brian M. – Science & Education, 2020
Conflation of sex and gender is implicated in the development of essentialist thinking, which has been linked to the justification of systems of prejudice in modern society. This exploratory study presents findings from a person randomized control trial conducted with 460 students in 8th-10th grade that investigated the extent to which students…

Donovan, Brian M.; Semmens, Rob; Keck, Phillip; Brimhall, Elizabeth; Busch, K. C.; Weindling, Monica; Duncan, Alex; Stuhlsatz, Molly; Bracey, Zoë Buck; Bloom, Mark; Kowalski, Susan; Salazar, Brae – Science Education, 2019
When people are exposed to information that leads them to overestimate the actual amount of genetic difference between racial groups, it can augment their racial biases. However, there is apparently no research that explores if the reverse is possible. Does teaching adolescents scientifically accurate information about genetic variation within and…

Daucourt, Mia C.; Erbeli, Florina; Little, Callie W.; Haughbrook, Rasheda; Hart, Sara A. – Scientific Studies of Reading, 2020
According to the Multiple Deficit Model, comorbidity results when the genetic and environmental risk factors that increase the liability for a disorder are domain-general. In order to explore the role of domain-general etiological risk factors in the co-occurrence of learning-related difficulties, the current meta-analysis compiled 38 studies of…

Donovan, Brian M. – Journal of Research in Science Teaching, 2017
For over a century, genetic arguments for the existence of racial inequality have been used to oppose policies that promote social equality. And, over that same time period, American biology textbooks have repeatedly discussed genetic differences between races. This experiment tests whether racial terminology in the biology curriculum causes…

Brouillard, Charlie; Brendgen, Mara; Vitaro, Frank; Dionne, Ginette; Boivin, Michel – Developmental Psychology, 2019
The present study used a genetically informed design of twins raised in the same family (375 monozygotic and 290 dizygotic twins; 50.2% girls) to examine the association between adolescents' genetic risk for depressive symptoms and the course of the parent-child relationship quality throughout adolescence. Depressive symptoms and the quality of…

Güccük, Ahmet; Köksal, Mustafa Serdar – Journal of Biological Education, 2017
The purpose of this study is to investigate the effects of case teaching on how students learn about genetic engineering, in terms of meaningful learning and retention of learning. The study was designed as quasi-experimental research including 63 8th graders (28 boys and 35 girls). To collect data, genetic engineering achievement tests were…

Sasmaz-Oren, Fatma; Karapinar, Aysegul; Sari, Kubranur; Demirer, Tugba – Journal of Theoretical Educational Science, 2022
In recent years, countries have focused specifically on improving thinking skills in their science education programs. One of the science lesson methods that can be used to activate the use of thinking processes is scientific scenarios. In this direction, the aim of the study is to investigate the effect of socioscientific subject-based…

Oztas, Haydar; Oztas, Fulya – Journal of Education and Practice, 2016
The aim of his study was to detect the misconceptions about heredity in secondary school (Middle school) 8th Grade pupils' Science courses. In order to perform a beneficial and useful science education it was necessary. The space of study was 8th grade pupils that the data obtained from research assessed via appreciated statistical methods.As a…

Freidenreich, Hava Bresler; Duncan, Ravit Golan; Shea, Nicole – International Journal of Science Education, 2011
Genetics is the cornerstone of modern biology and a critical aspect of scientific literacy. Research has shown, however, that many high school graduates lack fundamental understandings in genetics necessary to make informed decisions about issues and emerging technologies in this domain, such as genetic screening, genetically modified foods, etc.…

Donovan, Brian M. – Journal of Research in Science Teaching, 2014
Race has been a longstanding topic in the biology textbook curriculum. Yet, there appears to be no research investigating whether the treatment of race in modern biology textbooks impacts how students conceptualize race. In the present study, a double-blind field experiment employing mixed-methods is used to investigate the impact of…

Pittman, Phoebe J. Z.; Teske, Jolene K. – Journal of STEM Arts, Crafts, and Constructions, 2017
This practical lesson describes how students in six eighth grade science classes participated in a lesson combining the National Core Arts Standards with the Next Generation Science Standards. The goal of the lesson was to provide visual representations of finch beak form and function so students could better understand genetic variation and how…

Yilmaz, Diba; Tekkaya, Ceren; Sungur, Semra – International Journal of Science Education, 2011
The present study examined the comparative effects of a prediction/discussion-based learning cycle, conceptual change text (CCT), and traditional instructions on students' understanding of genetics concepts. A quasi-experimental research design of the pre-test-post-test non-equivalent control group was adopted. The three intact classes, taught by…

Koc, Isil; Turan, Merve – Science Activities: Classroom Projects and Curriculum Ideas, 2012
The cycle of duplication and division, known as the "cell cycle," is the essential mechanism by which all living organisms reproduce. This activity allows students to develop an understanding of the main events that occur during the typical eukaryotic cell cycle mostly in the process of mitotic phase that divides the duplicated genetic material…

Dogru-Atay, Pinar; Tekkaya, Ceren – Journal of Experimental Education, 2008
The authors investigated the comparative effect of the learning cycle and expository instruction on 8th-grade students' achievement in genetics. They adopted the nonequivalent control group design as a type of quasiexperimental design. The experimental group (N = 104) received learning cycle instruction, and the control group (N = 109) received…

Finnerty, Valerie Raunig – Science Scope, 2006
By the end of the eighth grade, students are expected to have a basic understanding of the mechanism of basic genetic inheritance. However, these concepts can be difficult to teach. In this article, the author introduces a new learning tool that will help facilitate student learning and enthusiasm to the basic concepts of genetic inheritance. This…
