Teunissen, Hanneke A.; Adelman, Caroline B.; Prinstein, Mitchell J.; Spijkerman, Renske; Poelen, Evelien A. P.; Engels, Rutger C. M. E.; Scholte, Ron H. J. – Journal of Abnormal Child Psychology, 2011
The transition to adolescence marks a time of sharply increased vulnerability to the development of depression, particularly among girls. Past research has examined isolated risk factors from individual theoretical models (e.g., biological, interpersonal, and cognitive) of depression, but few have examined integrative models. This study…

Durán, Pablo A.; Marshall, Jill A. – International Journal of Mathematical Education in Science and Technology, 2019
The purpose of this study was to investigate the mathematical needs of biological sciences undergraduate students. Student needs were measured through a needs assessment methodology scheme that included a content analysis of peer-reviewed journals, a nationwide cross-sectional survey, and semi-structured interviews. The research question that…

Thomure, Michael David – ProQuest LLC, 2014
I conduct a study of learning in HMAX-like models, which are hierarchical models of visual processing in biological vision systems. Such models compute a new representation for an image based on the similarity of image sub-parts to a number of specific patterns, called prototypes. Despite being a central piece of the overall model, the issue of…

Lin, Henry J.; Lehoang, Jennifer; Kwan, Isabel; Baghaee, Anita; Prasad, Priya; Ha-Chen, Stephanie J.; Moss, Tanesha; Woods, Jeremy D. – Biochemistry and Molecular Biology Education, 2018
The 8 studs on a 2 × 4 Lego brick conveniently represent the outer shell of electrons for carbon, nitrogen, and oxygen atoms. We used Lego bricks to model these atoms, which are then joined together to form molecules by following the Lewis octet rule. A variety of small biological molecules can be modeled in this way, such as most amino acids,…

Chiel, Hillel J.; McManus, Jeffrey M.; Shaw, Kendrick M. – CBE - Life Sciences Education, 2010
We describe the development of a course to teach modeling and mathematical analysis skills to students of biology and to teach biology to students with strong backgrounds in mathematics, physics, or engineering. The two groups of students have different ways of learning material and often have strong negative feelings toward the area of knowledge…

Malinak, Steven M.; Hertzog, Jerald E.; Pacilio, Julia E.; Polvani, Deborah A. – Journal of Chemical Education, 2019
Laboratory experiments that offer interdisciplinary experiences for students are appealing and are increasingly popular additions to undergraduate chemistry curricula. Students can capitalize on their knowledge of multiple areas of chemistry while working through an application, and this fosters the development of progressive problem-solving…

Vertolli, Michael O.; Kelly, Matthew A.; Davies, Jim – Cognitive Science, 2018
An incoherent visualization is when aspects of different senses of a word (e.g., the biological "mouse" vs. the computer "mouse") are present in the same visualization (e.g., a visualization of a biological mouse in the same image with a computer tower). We describe and implement a new model of creating contextual coherence in…

King, Gretchen P.; Bergan-Roller, Heather; Galt, Nicholas; Helikar, Tomáš; Dauer, Joseph T. – International Journal of Science Education, 2019
Model-based instruction offers numerous benefits to students, including increased content knowledge and critical thinking. This study explored the differences in the knowledge outcomes and reasoning processes employed by undergraduate students in an introductory biology lab as they constructed, revised, and simulated a computational model of a…

Dauer, Joseph T.; Bergan-Roller, Heather E.; King, Gretchen P.; Kjose, McKenzie; Galt, Nicholas J.; Helikar, Tomáš – International Journal of STEM Education, 2019
Background: Computational modeling is an increasingly common practice for disciplinary experts and therefore necessitates integration into science curricula. Computational models afford an opportunity for students to investigate the dynamics of biological systems, but there is significant gap in our knowledge of how these activities impact student…

Waxman, Sandra; Medin, Douglas – Human Development, 2007
This paper builds on Hatano and Inagaki's pioneering work on the role of experience and cultural models in children's biological reasoning. We use a category-based induction task to consider how experience and cultural models shape rural and urban children's patterns of biological reasoning. We discuss the implications of these findings for…

Yang, Allen H. J.; Dimiduk, Kathryn; Daniel, Susan – Chemical Engineering Education, 2011
We present a simplified human alcohol metabolism model for a mass balance team project. Students explore aspects of engineering in biotechnology: designing/modeling biological systems, testing the design/model, evaluating new conditions, and exploring cutting-edge "lab-on-a-chip" research. This project highlights chemical engineering's impact on…

Trujillo, Caleb M.; Anderson, Trevor R.; Pelaez, Nancy J. – CBE - Life Sciences Education, 2016
When undergraduate biology students learn to explain biological mechanisms, they face many challenges and may overestimate their understanding of living systems. Previously, we developed the MACH model of four components used by expert biologists to explain mechanisms: Methods, Analogies, Context, and How. This study explores the implementation of…

Graham, Steve – Educational Psychologist, 2018
This article presents a revised version of the writer(s)-within-community model of writing. Writing is conceptualized as a social activity situated within specific writing communities. Writing in these communities is accomplished by its members. The model proposes that writing is simultaneously shaped and bound by the characteristics, capacity,…

Lorber, Michael F.; Erlanger, Ann C. Eckardt; Slep, Amy M. Smith – Journal of Consulting and Clinical Psychology, 2013
Objective: Cardiovascular reactivity to laboratory stressors was investigated as (a) a moderator of associations of partner aggression with affective functioning, alcohol problems, and parenting; and (b) a consequence of partner aggression. Method: Cohabiting adult couples (N = 453) with 3- to 7-year-old children were recruited by random digit…

Keskin-Samanci, Nilay; Özer-Keskin, Melike; Arslan, Orhan – EURASIA Journal of Mathematics, Science & Technology Education, 2014
This study has led to the development of the "Bioethical Values Inventory" that can be used to reveal secondary school students' ethical values in decisions that they make during ethical debates regarding the application of biological sciences. An original inventory development model was used, consisting of four steps and involving…
