Infusing Technology: A Study of the Influence of Professional Development on How Teachers Use Technology

This study examined whether a quality professional development course, Infusing Technology, influenced the use of technology by elementary and middle school teachers in West Virginia. Infusing Technology was designed to help school-based team learning communities use technology in their instruction while engaging students in critical thinking, reasoning, and problem solving skills. This mixed-method study used the LoTi Digital-Age Survey, aligned with the National Educational Technology Standards, to collect quantitative data on levels of technology innovation, levels of personal computer use, and levels of current instructional practices. Participants in the Infusing Technology course completed the survey before the summer institute and after they had time to implement the content learned and focus groups were conducted following survey analysis. This allowed for pre-post comparison to determine the participants‘ progress integrating technology. This study found that Infusing Technology did not significantly change participants‘ LoTi Levels from pre to post based on the evaluation of the LoTi DigitalAge Survey. Focus group interviews supported these conclusions. Infusing Technology did appear to significantly increase participants‘ levels of personal computer use from pre to post based on the evaluation of the LoTi Digital-Age Survey. Focus group interviews supported these conclusions. Infusing Technology did appear to significantly increased participants‘ levels of current instructional practices from pre to post based on the evaluation of the LoTi Digital-Age Survey. Focus group interviews supported these conclusions. ualitative data from focus group interviews of participants identified constraints in the LoTi survey and focus group interviews, such as: (a) a lack of time to learn, practice, plan, and use technology with students, (b) lack of sufficient technology assistance, (c) equipment failure, (d) access to technology, (e) lack of technology knowledge or expertise for substitute teachers, and (f) other priorities (e.g., statewide testing, new textbook adoptions). Participants identified enablers in the LoTi Digital-Age Survey and focus group interviews, such as: (a) technology support from other classroom teachers, computer teachers, and school district specialists, (b) technology support from Infusing Technology mentors and presenters, (c) funding for new technology tools, and (d) motivation to use technology from administration endorsement

Flow Field Dynamics in a High-g Ultra-Compact Combustor

The Ultra Compact Combustor (UCC) presents a novel solution to the advancement of aircraft gas turbine engine performance. A high-g UCC design operates by diverting a portion of the axial compressor flow into a circumferential combustion cavity positioned about the engine outer diameter. The circumferential cavity (CC) provides the necessary residence length and time for combustion within reduced axial lengths; furthermore, high rates of centrifugal acceleration termed high-g loading are imposed upon the swirling cavity flow. These high-g conditions are hypothesized to increase flame speed, reduce flame length, and improve lean blow-out performance. Work at AFIT was sponsored by the Air Force Office of Scientific Research to study high-g combustion. This research capitalized on the availability of advanced flow diagnostic data coupled with a computational fluid dynamics (CFD) model to provide detailed insight into the high-g flow field and combustion dynamics. Results indicated that combustion could be sustained and controlled in a manner suitable for integration into modern gas turbine engine architecture

Extreme alpha-clustering in the 18O nucleus

The structure of the 18O nucleus at excitation energies above the alpha decay threshold was studied using 14C+alpha resonance elastic scattering. A number of states with large alpha reduced widths have been observed, indicating that the alpha-cluster degree of freedom plays an important role in this N not equal Z nucleus. However, the alpha-cluster structure of this nucleus is very different from the relatively simple pattern of strong alpha-cluster quasi-rotational bands in the neighboring 16O and 20Ne nuclei. A 0+ state with an alpha reduced width exceeding the single particle limit was identified at an excitation energy of 9.9+/-0.3 MeV. We discuss evidence that states of this kind are common in light nuclei and give possible explanations of this feature.Comment: 4 pages, 2 figures, 1 table.

Finite reduction and Morse index estimates for mechanical systems

A simple version of exact finite dimensional reduction for the variational setting of mechanical systems is presented. It is worked out by means of a thorough global version of the implicit function theorem for monotone operators. Moreover, the Hessian of the reduced function preserves all the relevant information of the original one, by Schur's complement, which spontaneously appears in this context. Finally, the results are straightforwardly extended to the case of a Dirichlet problem on a bounded domain.Comment: 13 pages; v2: minor changes, to appear in Nonlinear Differential Equations and Application

Euniwell: Maximising Academic And Social Outcomes In Engineering Education

The ERASMUS+ European University for Well-Being (EUniWell) alliance’s mission aims to resolve the paradox of Europeans’ relative prosperity against the global security and sustainability challenge. “Maximising Academic and Social Outcomes in Engineering Education” is a project which interprets this contradiction for engineering educators; how to best teach non-technical skills to ensure engineers make the utmost contribution to societal wellbeing? Appreciably, the social outcome for the person who becomes an engineer is positive because the profession is relatively well-paid. Therefore, engineering education is good for social mobility providing the learning environment narrows attainment gaps between disadvantaged and mainstream cohorts. Accordingly, our strategy is to bring together the expertise of the British, French, Italian and Swedish faculties to transfer best practice for professional, business and sustainability skill teaching, while contrasting how their disadvantaged cohorts present. The project has two primary objectives: To understand how partners differ in terms of skill teaching, and how students from disadvantaged backgrounds are accommodated. The paper describes the background and rationale of the project, and its research design and methodology. Although the project is still in progress and data collection is still underway, this paper provides insights and perspectives for engineering educators looking to design similar collaborations to share best practice, while considering engineering identities and their underlying competencies

Octupole strength in the neutron-rich calcium isotopes

Low-lying excited states of the neutron-rich calcium isotopes $^{48-52}$Ca have been studied via $\gamma$-ray spectroscopy following inverse-kinematics proton scattering on a liquid hydrogen target using the GRETINA $\gamma$-ray tracking array. The energies and strengths of the octupole states in these isotopes are remarkably constant, indicating that these states are dominated by proton excitations.Comment: 15 pages, 3 figure

News discourses on distant suffering: A critical discourse analysis of the 2003 SARS outbreak

News carries a unique signifying power, a power to represent events in particular ways (Fairclough, 1995). Applying Critical Discourse Analysis and Chouliaraki's theory on the mediation of suffering (2006), this article explores the news representation of the 2003 global SARS outbreak. Following a case-based methodology, we investigate how two Belgian television stations have covered the international outbreak of SARS. By looking into the mediation of four selected discursive moments, underlying discourses of power, hierarchy and compassion were unraveled. The analysis further identified the key role of proximity in international news reporting and supports the claim that Western news media mainly reproduce a Euro-American centered world order. This article argues that news coverage of international crises such as SARS constructs and maintains the socio-cultural difference between 'us' and 'them' as well as articulating global power hierarchies and a division of the world in zones of poverty and prosperity, danger and safety
