Direct linkLang, Franziska K. – ProQuest LLC, 2018
Research investigating faculty and instructors' perception of teaching in discipline-oriented fields such as biology, chemistry and physics suggest that faculty hold diverse conceptions about teaching and learning. This study extended this work to a discipline at the interface between traditional physical science and life science fields,…

Peer reviewedSiu, Michelle T.; Goodman, Sarah J.; Yellan, Isaac; Butcher, Darci T.; Jangjoo, Maryam; Grafodatskaya, Daria; Rajendram, Rageen; Lou, Youliang; Zhang, Rujun; Zhao, Chunhua; Nicolson, Rob; Georgiades, Stelios; Szatmari, Peter; Scherer, Stephen W.; Roberts, Wendy; Anagnostou, Evdokia; Weksberg, Rosanna – Journal of Autism and Developmental Disorders, 2021
Many neurodevelopmental disorders (NDDs) share common learning and behavioural impairments, as well as features such as dysregulation of the oxytocin hormone. Here, we examined DNA methylation (DNAm) in the 1st intron of the oxytocin receptor gene, "OXTR," in patients with autism spectrum (ASD), attention deficit and hyperactivity (ADHD)…

Dries, Daniel R.; Dean, Diane M.; Listenberger, Laura L.; Novak, Walter R. P.; Franzen, Margaret A.; Craig, Paul A. – Biochemistry and Molecular Biology Education, 2017
A thorough understanding of the molecular biosciences requires the ability to visualize and manipulate molecules in order to interpret results or to generate hypotheses. While many instructors in biochemistry and molecular biology use visual representations, few indicate that they explicitly teach visual literacy. One reason is the need for a list…

Miller, Kathryn; Kim, Thomas – Biochemistry and Molecular Biology Education, 2017
This study investigates the role of representational competence in student responses to an assessment of hydrogen bonding. The assessment couples the use of a multiple-select item ("Choose all that apply") with an open-ended item to allow for an examination of students' cognitive processes as they relate to the assignment of hydrogen…

Mavor, David Carl – ProQuest LLC, 2017
Ubiquitin is essential for eukaryotic life and varies in only 3 amino acid positions between yeast and humans. However, recent deep sequencing studies indicate that ubiquitin is highly tolerant to single mutations. We hypothesized that this tolerance would be reduced by chemically induced physiologic perturbations. To test this hypothesis, a class…

King, Matthew D.; Phillips, Paul; Turner, Matthew W.; Katz, Michael; Lew, Sarah; Bradburn, Sarah; Andersen, Tim; McDougal, Owen M. – Biochemistry and Molecular Biology Education, 2016
Computational molecular docking is a fast and effective "in silico" method for the analysis of binding between a protein receptor model and a ligand. The visualization and manipulation of protein to ligand binding in three-dimensional space represents a powerful tool in the biochemistry curriculum to enhance student learning. The…

Weers, Paul M. M.; Prenner, Elmar J.; Curic, Spomenka; Lohmeier-Vogel, Elke M. – Biochemistry and Molecular Biology Education, 2016
The laboratory protocol presented here takes about 3 hours to perform and investigates protein and lipid interactions. Students first purify His6-tagged human apolipoprotein A-I (apoA-I) with Ni-NTA affinity resin in a simple batch protocol and prepare multilamellar vesicles (MLV) from pre-dried phospholipid films. When apoA-I is added to the MLV,…

Girardi, Bruna Amanda; Ribeiro, Daniela Aymone; Signor, Cristiane; Muller, Michele; Gais, Mayara Ana; Mello, Carlos Fernando; Rubin, Maribel Antonello – Learning & Memory, 2016
In this study, we determined whether the calcium-dependent protein kinase (PKC) signaling pathway is involved in the improvement of fear memory reconsolidation induced by the intrahippocampal administration of spermidine in rats. Male Wistar rats were trained in a fear conditioning apparatus using a 0.4-mA footshock as an unconditioned stimulus.…

Akkerman, Sven; Blokland, Arjan; Prickaerts, Jos – Learning & Memory, 2016
In previous studies, we have shown that acetylcholinesterase inhibitors and phosphodiesterase inhibitors (PDE-Is) are able to improve object memory by enhancing acquisition processes. On the other hand, only PDE-Is improve consolidation processes. Here we show that the cholinesterase inhibitor donepezil also improves memory performance when…

Ward, Rose Marie; McMurrary, Matthew; Brinkman, Craig; Taylor, Elizabeth A.; Witmer, Kathryn A.; Bonar, Robert N.; Lewis, Patrick – Journal of Alcohol and Drug Education, 2019
When trying to prevent deaths from alcohol overdose, potentially intoxicated companions of the inebriated person must know when to intervene. The current project examined the relation between intoxication level and the signs of alcohol poisoning. In a local bar district, interviewers asked college students (N = 178; 52% female students) to…

Lee, Hae Yeon; Jamieson, Jeremy P.; Miu, Adriana S.; Josephs, Robert A.; Yeager, David S. – Child Development, 2019
Grades often decline during the high school transition, creating stress. The present research integrates the biopsychosocial model of challenge and threat with the implicit theories model to understand who shows maladaptive stress responses. A diary study measured declines in grades in the first few months of high school: salivary cortisol…

The present study aims to examine the implementation of a stepwise inquiry approach to improving communication skills and scientific attitudes. Stepwise inquiry comprises structured inquiry, guided inquiry, and open inquiry. The variables measured were communication skills and scientific attitudes. The construct used to measure communication…

Hennessy, Sara; Calcagni, Elisa; Leung, Alvin; Mercer, Neil – Language and Education, 2023
Dialogic approaches based on active student participation, open, respectful discussion, exploring and critiquing different perspectives are increasingly found to support student learning. However, the specific productive forms of teacher-student interaction have rarely been studied systematically. A recent large-scale project explored the…

Mahaffey, Angela L. – Biochemistry and Molecular Biology Education, 2020
DNA analysis is a common diagnostic tool in healthcare: ranging from microbial typing (e.g. DNA strands of viral, bacterial and even fungal pathogens), oncological screen (e.g. Breast cancer detection via DNA analysis of any BRCA gene mutations), genetic amniocentesis test (a medical technique used in determining chromosomal conditions such as…

Gao, Ruomei; Lloyd, Judith; Kim, Youngjoo – Journal of Chemical Education, 2020
The COVID-19 outbreak has altered chemistry laboratory instruction and forced us to reconsider the balance between face-to-face and online teaching. Our students preferred face-to-face teaching (score 4.1/5 on a Likert-like scale) to virtual laboratory exercises (3.4/5) despite the fact that their performance score was actually lower in…
