Achievement And Engagement With The Workshop Model In The High School Literature Classroom
The research question addressed in this study is as follows: does the use of the workshop model improve engagement and achievement in an honors senior level literature classroom? This action research study sought to discover how two workshop treatment groups, Blau’s literature workshop and Tovani’s workshop model, compared to a control group in achievement on the target unit learning objectives and engagement change over the unit with high school honors-level senior students. Using pre- and post-treatment surveys, focus group discussion, and a unit test, this mixed-method research project looked for a parallel between increase engagement and achievement. Engagement measures under study here mirror Skinner et al. (2008) and include behavioral engagement, behavioral disengagement, emotional engagement, emotion disengagement, perceived competency, autonomy orientation, sense of relatedness, teacher support, and class agency. The data did not show a positive correlation between gains in engagement and achievement; in fact, a reverse trend from the current research on the topic occurred. This capstone also gives insight into the workshop model facets that were most beneficial to increasing engagement
Exploration in Design, Graphic Communications and the Creative Process
In lieu of the traditional thesis, I have chosen to culminate the Master of Arts in Related Arts program with a creative project and a paper that describes and evaluates the completion of the project. The project involved a personal aesthetic and technical development of the aesthetic in graphic design and communications. Documentation of the creative arts project is presented in a portfolio which includes graphic designs, publications, and news feature stories. The project is interdisciplinary in that it involves skills in art (design) and English (writing) as well as effective interdisciplinary communication skills necessary to produce interdepartmental publications.
Included in the portfolio are: a resume; Celebration ‘80 program and flyers; letterhead, business card, and opening invitations for the Art Gallery Co-op; poster and program for the play Only an Orphan Girl ; the graduate art exhibition catalog; public relations articles about Celebration ’80 and Only an Orphan Girl ; news feature articles about the arts; and Around the Arts, an Eastern Illinois University School of Fine Arts publication.
The paper describes and evaluates the completion of the creative arts project by exploring varying philosophies encountered while working on the creative arts project concerning the nature of art and the creative process. The paper also explores the effectiveness of the materials of the portfolio in terms of integration of the visual and written aspects and the elements of design. The paper discusses line, color, shape, texture, and form as related to the materials of the portfolio. The conclusion of the paper is specifically addressed to a description of the creative process with examples given from the process of designing the materials of the portfolio
An Analysis of Front Page News Pertaining to Juveniles in South Dakota Daily Newspapers for the First Three Months of 1960 with Regard to Favorable and Unfavorable Content
Newspapers have often been accused of emphasizing the sensational giving minimum attention to the non-violent or “good” news in which young people are involved. Evidence to support or to disprove such accusations has, however, been lacking. The accusations have evidently been made on a basis of casual, informal observation of the media and on the basis of public opinion polls. The teen age group, then, is in the public eye and the impression which the public gets is perhaps obtained largely through the mass media. The question which arises would be, “is the press fair in its presentation by Gilbert suggest, present a one sided picture?” It was hoped that through such a study it would be possible to determine the extent of difference, if say, between display treatments given front page stories juveniles in socially approved roles and stories monitoring juveniles in socially disapproved roles. Each story mentioning teen-agers which appeared on the front page of a South Dakota daily newspaper during the three month period was studied in terms of the news role played by the youth, and the space and display given the story by the newspaper
JACIE: A Model Partnership
The National Aeronautics and Space Administration (NASA), National Oceanic and Atmospheric Administration (NOAA), the United States Department of Agriculture (USDA), and the United States Geological Survey (USGS), and their associates and partners, are directly responsible for establishing and leading a unique interagency team of scientists and engineers who work together to evaluate and enhance the quality remote sensing data for commercial and government use. This team is called "the Joint Agency Commercial Imagery Evaluation (JACIE) team". The team works together to define, prioritize, assign, and assess civil and commercial image quality and jointly sponsors an annual JACIE Civil Commercial Imagery Evaluation workshop with participation support from the remote sensing calibration and validation science community
Medium Spatial Resolution Satellite Characterization
This project provides characterization and calibration of aerial and satellite systems in support of quality acquisition and understanding of remote sensing data, and verifies and validates the associated data products with respect to ground and and atmospheric truth so that accurate value-added science can be performed. The project also provides assessment of new remote sensing technologies
A chronic pain: inflammation-dependent chemoreceptor adaptation in rat carotid body
Producción CientíficaExperiments in recent years have revealed labile electrophysiological and neurochemical
phenotypes in primary afferent neurons exposed to specific stimulus conditions associated with
the development of chronic pain. These studies collectively demonstrate that the mechanisms
responsible for functional plasticity are primarily mediated by novel neuroimmune interactions
involving circulating and resident immune cells and their secretory products, which together
induce hyperexcitability in the primary sensory neurons. In another peripheral sensory modality,
namely the arterial chemoreceptors, sustained stimulation in the form of chronic hypoxia (CH)
elicits increased chemoafferent excitability from the mammalian carotid body. Previous studies
which focused on functional changes in oxygen-sensitive type I cells in this organ have only
partially elucidated the molecular and cellular mechanisms which initiate and control this adaptive
response. Recent studies in our laboratory indicate a unique role for the immune system in
regulating the chemo-adaptive response of the carotid body to physiologically relevant levels of
hypoxia
Basal lamina formation at the site of spinal cord transection
The pia-glial basal lamina (BL) at the site of spinal cord injury could be an important physical impediment to central nervous system regeneration. We used an epithelial BL-specific immunohistochemical stain to determine the location of the pia-glial BL after spinal cord transection. Small segments of BL were found at the margin of the lesion 5 days after transection. After 10 days, longer and more numerous segments were seen. At 20 days, the entire transected end of the spinal cord was capped by a layer of BL.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/50298/1/410080204_ftp.pd
Axon regeneration across the site of injury in the optic nerve of the newt Triturus pyrrhogaster
The process by which axons regenerate following a freeze injury to the optic nerve of the newt was analyzed by light and electron microscopy. Freezing destroys cellular constituents in a one millimeter segment of the nerve, leaving intact the basal lamina and the blood supply to the eye. No axons are seen at the site of injury one to seven days post lesion. This contrasts with the persistence of normal-appearing but severed unmyelinated axons within the cranial stump which thus give a false appearance of early regeneration. The first axon sprouts traverse the lesion and enter the cranial stump by ten days. The number of regenerating axons increases rapidly thereafter with no signs of random growth at the site of injury. These axon sprouts tend to be somewhat larger than normal unmyelinated axons and contain dense core vesicles and abnormal organelles similar to those in growing axons in tissue culture. The persisting basal lamina inside the optic sheath appears to provide continuity across the site of injury, to orient axon sprouts, and to favor an orderly process of axon regeneration without neuroma formation.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47666/1/441_2004_Article_BF00219852.pd
Neurons of the Dentate Molecular Layer in the Rabbit Hippocampus
The molecular layer of the dentate gyrus appears as the main entrance gate for information into the hippocampus, i.e., where the perforant path axons from the entorhinal cortex synapse onto the spines and dendrites of granule cells. A few dispersed neuronal somata appear intermingled in between and probably control the flow of information in this area. In rabbits, the number of neurons in the molecular layer increases in the first week of postnatal life and then stabilizes to appear permanent and heterogeneous over the individuals’ life span, including old animals. By means of Golgi impregnations, NADPH histochemistry, immunocytochemical stainings and intracellular labelings (lucifer yellow and biocytin injections), eight neuronal morphological types have been detected in the molecular layer of developing adult and old rabbits. Six of them appear as interneurons displaying smooth dendrites and GABA immunoreactivity: those here called as globoid, vertical, small horizontal, large horizontal, inverted pyramidal and polymorphic. Additionally there are two GABA negative types: the sarmentous and ectopic granular neurons. The distribution of the somata and dendritic trees of these neurons shows preferences for a definite sublayer of the molecular layer: small horizontal, sarmentous and inverted pyramidal neurons are preferably found in the outer third of the molecular layer; vertical, globoid and polymorph neurons locate the intermediate third, while large horizontal and ectopic granular neurons occupy the inner third or the juxtagranular molecular layer. Our results reveal substantial differences in the morphology and electrophysiological behaviour between each neuronal archetype in the dentate molecular layer, allowing us to propose a new classification for this neural population
The role of NADPH oxidase in carotid body arterial chemoreceptors
Producción CientíficaO2-sensing in the carotid body occurs in neuroectoderm-derived type I glomus cells where hypoxia elicits a complex chemotransduction cascade
involving membrane depolarization, Ca2+ entry and the release of excitatory neurotransmitters. Efforts to understand the exquisite O2-sensitivity of
these cells currently focus on the coupling between local PO2 and the open-closed state of K+-channels. Amongst multiple competing hypotheses
is the notion that K+-channel activity is mediated by a phagocytic-like multisubunit enzyme, NADPH oxidase, which produces reactive oxygen
species (ROS) in proportion to the prevailing PO2. In O2-sensitive cells of lung neuroepithelial bodies (NEB), multiple studies confirm that ROS
levels decrease in hypoxia, and that EM and K+-channel activity are indeed controlled by ROS produced by NADPH oxidase. However, recent
studies in our laboratories suggest that ROS generated by a non-phagocyte isoform of the oxidase are important contributors to chemotransduction,
but that their role in type I cells differs fundamentally from the mechanism utilized by NEB chemoreceptors. Data indicate that in response to
hypoxia, NADPH oxidase activity is increased in type I cells, and further, that increased ROS levels generated in response to low-O2 facilitate cell
repolarization via specific subsets of K+-channels
