Environmental Research With Undergraduates In East Asia: Collaborations In China And Japan, Gary A. Morris, Jon Schoer
Environmental Research With Undergraduates In East Asia: Collaborations In China And Japan, Gary A. Morris, Jon Schoer
Gary A. Morris
China: From 2007-2008 as part of a collaborative research project funded by the ASIANetwork, VU and the VLACD, 5 VU students (2 chemistry, 1 biology, 1 environmental science, and 1 civil engineering) spent 3 weeks in Zhejiang province, China and 7 additional weeks in northwest Indiana comparing and contrasting water quality issues and attitudes in the two regions. While in China, the students interacted with one another and graduate students, faculty, and staff from Zhejiang University and Zhejiang A &F University, and with multiple local & regional officials and residents to collect water quality data and opinions about key water …

Dr. Et-touhami Es-sebbar
Saturn's largest satellite, Titan, is the only one in the Solar System known to have a thick N2/CH4, planet like atmosphere. The dissociation of these principal components and the recombination of the products make this atmosphere to be rich in organic compounds of high interest for astrobiology. Solar and stellar occultations observed by the Ultraviolet Imaging Spectrograph (UVIS) on board the Cassini spacecraft can be used to characterize the composition of Titan’s upper atmosphere (400 – 1400 km). The results depend strongly on the knowledge of the molecular absorption cross sections of the atmospheric constituents (Ferradaz et al. 2009). This …
Stereoscopic Visualization As A Tool For Learning Astronomy Concepts, Norman M. Joseph
Stereoscopic Visualization As A Tool For Learning Astronomy Concepts, Norman M. Joseph
Department of Computer Graphics Technology Degree Theses
Three-dimensional (3D) visualization is becoming an extensively used educational tool. 3D visualization tends to be most useful when demonstrating concepts involving the very large – such as astronomy, or the very small – such as nanotechnology. Stereo visualization allows students to familiarize and immerse themselves in worlds which are difficult or impossible to experience in real life. This study will evaluate the educational benefit of teaching lessons involving a highly spatially-oriented topic (astronomy) using stereoscopic visualization technology.
We have used a stereoscopic visualization system, installed in a classroom, to deploy 3D simulation packages for use in classroom instruction. This educational …

Dr. Et-touhami Es-sebbar
Low-temperature hydrogen plasmas are widely used as continuous vacuum ultraviolet irradiation sources in photochemical studies and, in particular, in laboratory simulations of planetary atmospheres. One of the most challenging objectives of such experiments is to retrieve accurate quantitative laboratory data allowing a reliable comparison with theoretical and/or observational ones. This task can only be achieved when the irradiation source delivers a well characterised radiation in terms of flux and wavelength dependency. As an example, we will present a study, developed in the frame of a program dedicated to simulations of Titan’s atmosphere, on methane photolysis at Lyman alpha (121.6 nm). …

The Effects Of Seductive Details In An Inflatable Planetarium, Sean Gillette
The Effects Of Seductive Details In An Inflatable Planetarium, Sean Gillette
Walden Dissertations and Doctoral Studies
Astronomy is becoming a forgotten science, which is evident by its relatively low enrollment figures compared to biology, chemistry, and physics. A portable inflatable planetarium brings relevance back to astronomy and offers support to students and educators by simulating realistic astronomical environments. This study sought to determine if learning is improved in an inflatable planetarium by adhering to the design principles of the cognitive theory of multimedia learning (CTML), specifically the coherence principle, in an authentic classroom. Two groups of 5th grade students of similar ability were purposefully assigned using a 1-teacher-to-many-students format with mean lesson lengths of 34 minutes. …
