Dhawan, Gagan; Singh, Indu; Dhawan, Uma; Kumar, Pradeep – Journal of Chemical Education, 2021
Nanoparticle synthesis is an important area of nanotechnology and has been performed by undergraduate students from various universities across the globe. Due to the availability of massive data on the synthesis of a wide variety of metallic nanoparticles, including silver, gold, selenium, zinc, copper, iron, palladium, platinum, titanium, etc.,…

Crowther, Gregory J.; Wiggins, Benjamin L.; Jenkins, Lekelia D. – HAPS Educator, 2020
Many undergraduate biology instructors incorporate active learning exercises into their lessons while continuing to assess students with traditional exams. To better align practice and exams, we present an approach to question-asking that emphasizes templates instead of specific questions. Students and instructors can use these Test Question…

Dai, Ting; Van Boekel, Martin; Cromley, Jennifer; Nelson, Frank; Fechter, Tia – Grantee Submission, 2018
This case study describes how our research team conducted the qualitative think-aloud approach (or cognitive pretesting) to obtaining cognitive validity evidence for a biology inference-making and reasoning measure for undergraduate students. The main goal of our work was to gather high-quality student think-aloud data of reasoning while they were…

Daniela, Linda, Ed.; Lytras, Miltiadis, Ed. – IGI Global, 2018
Educational strategies have evolved over the years due to research breakthroughs and the application of technology. By using the latest learning innovations, curriculum and instructional design can be enhanced and strengthened. Also, as learners move away from traditional scholarly media and toward technology-based education, students gain an…

Leppien, Jann H.; Purcell, Jeanne H. – Corwin, 2011
Based on the best-selling book "The Parallel Curriculum", this professional development resource gives multifaceted examples of rigorous learning opportunities for science students in Grades 6-12. The four sample units revolve around genetics, the convergence of science and society, the integration of language arts and biology, and the periodic…

Rauter, Claudia M. – Bioscene: Journal of College Biology Teaching, 2010
This laboratory exercise investigates the influence of population density on offspring number and size in burying beetles. Students test the theoretical predictions that brood size declines and offspring size increases when competition over resources becomes stronger with increasing population density. Students design the experiment, collect and…

The Strasbourg University PhD school in Life and Health Sciences launched an initiative called "OpenLAB." This project was developed in an effort to help high school teenagers understand theoretical and abstract concepts in genetics. A second objective of this program is to help students in defining their future orientation and to…

Jones, Thomas C.; Laughlin, Thomas F. – American Biology Teacher, 2010
Natural selection and other components of evolutionary theory are known to be particularly challenging concepts for students to understand. To help illustrate these concepts, we developed a simulation model of microevolutionary processes. The model features all the components of Hardy-Weinberg theory, with population size, selection, gene flow,…

Ellington, Roni; Wachira, James; Nkwanta, Asamoah – CBE - Life Sciences Education, 2010
The focus of this Research Experience for Undergraduates (REU) project was on RNA secondary structure prediction by using a lattice walk approach. The lattice walk approach is a combinatorial and computational biology method used to enumerate possible secondary structures and predict RNA secondary structure from RNA sequences. The method uses…

Adler, Jacob J.; Judd, Mariah V.; Bringman, Lauren R.; Wells, Clark D.; Marrs, Kathleen A. – American Biology Teacher, 2013
We developed an interactive laboratory that allows students to identify and grade tissue samples from human breast biopsies, using techniques similar to those used by actual pathologists. This unique lab develops a practical and intellectual understanding of basic tissue structures that make up living systems, utilizing technology to bring…

Caudill, Lester; Hill, April; Hoke, Kathy; Lipan, Ovidiu – CBE - Life Sciences Education, 2010
Funded by innovative programs at the National Science Foundation and the Howard Hughes Medical Institute, University of Richmond faculty in biology, chemistry, mathematics, physics, and computer science teamed up to offer first- and second-year students the opportunity to contribute to vibrant, interdisciplinary research projects. The result was…

Donnelly, Lisa A.; Kazempour, Mahsa; Amirshokoohi, Aidin – Research in Science Education, 2009
Evolution is an important and sometimes controversial component of high school biology. In this study, we used a mixed methods approach to explore students' evolution acceptance and views of evolution teaching and learning. Students explained their acceptance and rejection of evolution in terms of evidence and conflicts with religion and…

Zhang, Xiaorong – Biochemistry and Molecular Biology Education, 2009
This article describes a new approach to teaching bioinformatics using "Arabidopsis" genetic sequences. Several open-ended and inquiry-based laboratory exercises have been designed to help students grasp key concepts and gain practical skills in bioinformatics, using "Arabidopsis" leucine-rich repeat receptor-like kinase (LRR…

Zurcher, Ulrich – European Journal of Physics, 2008
Students often have great difficulties with applications of the energy principle, especially those from biology, although most introductory physics texts include a brief discussion of metabolism. We point out that many of these discussions are unsatisfactory, since they often fail to mention how biological systems are "thermal systems in…

Gragson, Derek E.; Beaman, Dan; Porter, Rhiannon – Journal of Chemical Education, 2008
Two experiments are described in which students explore phase transitions and critical phenomena by obtaining compression isotherms of phospholipid monolayers using a Langmuir trough. Through relatively simple analysis of their data students gain a better understanding of compression isotherms, the application of the Clapeyron equation, the…
