The experience of three flipped classrooms in an urban university: an exploration of design principles

Abstract: As a response to the call for technology enhanced, student-centered learning environments, the flipped classroom approach has drawn much attention from both the research and practice communities. Despite over fifteen years of flipped classroom implementation, design principles have been minimally elaborated upon in relation to diverse disciplinary contexts. Focusing on this gap, we engaged in a mixed methods study that examined three instances of the flipped classroom across unique disciplines and to extract specific design principles. Three instructors and 115 students enrolled in three separate classes in fall 2012 participated in the study. Building upon the Revised Community of Inquiry Framework, we developed a flipped classroom design framework and identified nine design principles.

Animal migration and infectious disease risk.

Abstract: Animal migrations are often spectacular, and migratory species harbor zoonotic pathogens of importance to humans. Animal migrations are expected to enhance the global spread of pathogens and facilitate cross-species transmission. This does happen, but new research has also shown that migration allows hosts to escape from infected habitats, reduces disease levels when infected animals do not migrate successfully, and may lead to the evolution of less-virulent pathogens. Migratory demands can also reduce immune function, with consequences for host susceptibility and mortality. Studies of pathogen dynamics in migratory species and how these will respond to global change are urgently needed to predict future disease risks for wildlife and humans alike.

Spectral signatures of hydrated proton vibrations in water clusters.

Abstract: The ease with which the pH of water is measured obscures the fact that there is presently no clear molecular description for the hydrated proton. The mid-infrared spectrum of bulk aqueous acid, for example, is too diffuse to establish the roles of the putative Eigen (H 3 O + ) and Zundel (H 5 O 2 + ) ion cores. To expose the local environment of the excess charge, we report how the vibrational spectrum of protonated water clusters evolves in the size range from 2 to 11 water molecules. Signature bands indicating embedded Eigen or Zundel limiting forms are observed in all of the spectra with the exception of the three- and five-membered clusters. These unique species display bands appearing at intermediate energies, reflecting asymmetric solvation of the core ion. Taken together, the data reveal the pronounced spectral impact of subtle changes in the hydration environment.

The construct of the learning organization: Dimensions, measurement, and validation

Abstract: This research describes efforts to develop and validate a multidimensional measure of the learning organization. An instrument was developed based on a critical review of both the conceptualization and practice of this construct. Supporting validity evidence for the instrument was obtained from several sources, including best model-data fit among alternative measurement models, nomological network among dimensions of the learning organization, and organizational performance outcomes. Acceptable reliability estimates were obtained for the seven proposed dimensions. Consequently, the instrument, Dimensions of the Learning Organization Questionnaire, was recommended for use in organizational studies.
