    Teacher Evaluation Process In Evangelical Christian Schools

    Get PDF
    The difficulty in developing an effective program of teacher evaluation is seen in the literature as stemming from the administrators\u27 and teachers\u27 different perspectives of evaluation. In this tenor the problem investigated four facets of an evaluation process: the need, purpose, procedure, and result of a teacher evaluation program found in evangelical Christian schools. The purpose was fourfold: To compare the responses of the experienced, Christian day-school teacher to those of the administrator of the Christian day-school as to the (1) need, (2) purpose, (3) procedure, and (4) result of an evaluation process found in their schools. The study was conducted in sixty-six Christian schools throughout California. Each institution had an enrollment of 400 students or more and a teaching staff of twelve or more members. An instrument based on Redfern\u27s evaluation plan was used to survey the population. One-way analysis of variance procedures was used to test Hypotheses 1-11. The findings showed differences in agreement with respect to responses among Christian educators in terms of their perceptions of a teacher evaluation process. There were many differences with regard to having a need for an evaluation process and its results. Differences were evidenced with respect to purposes of an evaluation process. There were a few differences with regard to guidelines in evaluation procedures. There were many differences in terms of characteristics of and post-activities following an evaluation conference, appropriateness of the criteria for evaluations, and the attempt of the administration to clearly define criteria used. However, the findings evidenced agreement with regard to having a pre-conference and what areas are discussed within that conference. Further replication studies among schools with enrollment of less than 400 and fewer than twelve teachers, studies using other experts\u27 evaluation plans, broadening of the school of the study to a national survey and studies indicating what priorities of evaluation may exist are recommended

    Work in Progress - Designing for Economic Empowerment in Nicaragua

    Get PDF
    Faculty and students in several disciplines at four institutions in the United States and Nicaragua are collaborating on technology entrepreneurship education for economic empowerment in Esteli, Nicaragua. The project aims to demonstrate a new paradigm for development that is rooted in education. The effort will focus on design and delivery of new curriculum for collaborative, interdisciplinary product development. To demonstrate the curriculum, the effort will launch cross-cultural student teams to identify and develop markets, partners, and technology for entrepreneurial ventures in Nicaragua, utilizing Nicaraguan materials and skills. The envisioned long term goal is local economic empowerment and a sound, collaborative process for technology innovation and product development that is both replicable and transferable. The proposed program includes six sequential phases; phase one is complete and phase two is in progress. This paper discusses the goals, results, and assessment of the first two phases in the context of the ongoing project

    Mussel Inventory and Population Status of the Federally Endangered Potamilus capax (Green 1832) in the Tyronza River, Arkansas

    Currently, few data exist for the mussel assemblages of the Tyronza River, Arkansas. The goal of this project was to inventory the freshwater mussel assemblages of the Tyronza River and determine the status of the federally endangered Potamilus capax. We qualitatively and quantitatively sampled mussel assemblages and documented the occurrence of S1 (extremely rare), S2 (very rare), and S3 (rare to uncommon) species. A total of 70.4 river kilometers were sampled in 2006 and 2007 resulting in 363 sampling sites, 4030 live individuals, and 25 species. We observed a total of 1 S1, 2 S2, and 9 S3 species. Mean catch-per-unit-of-effort was 0.9 (1.2 SD) individuals / min. and mean species richness and individual abundance were 3.4 (2.7 SD) species / site and 11.1 (15.1 SD) individuals / site, respectively. Thirteen Potamilus capax were collected during this survey, with only 1 gravid female and 2 juveniles. Quantitative survey mean densities per site ranged from 1.0 to 1.9 mussels / m2 with an overall mean of 1.4 individuals / m2 (0.3 SD). A total of 7 Potamilus capax were observed during quantitative sampling. Community Numerical Standing Crop estimates ranged from 70 ± 30 to 22,986 ± 7,905 individuals. The data collected from this survey provide a valuable baseline on the mussel assemblages of an altered-alluvial river and the location and status of all S1, S2 and S3 species. This information is essential to the management of this imperiled fauna in the Tyronza River

    Consideration of the carrier-based tactical support center design

    Get PDF
    This joint thesis analyzes the carrier-based Tactical Support Center (CV-TSC) design from a human factors engineering viewpoint. Beginning with the ASW threat to the carrier force under the CV concept, a definition of the mission of the CV/TSC is presented. System functions are identified and developed into man-machine relationships of the CV/TSC. A comprehensive, albeit general, description of TSC components is included as part of the system analysis. Man's role, functions and tasks in the CV/TSC are identified and form the basis for alternatives to the current TSC display/control console.http://archive.org/details/considerationofc00farrLieutenant, United States NavyApproved for public release; distribution is unlimited

    Do precision electroweak constraints guarantee e+ee^+e^- collider discovery of at least one Higgs boson of a two-Higgs-doublet model?

    Get PDF
    We consider a CP-conserving two-Higgs-doublet type II model with a light scalar or pseudoscalar neutral Higgs boson (\h=\hl or \h=\ha) that has no ZZ/WWZZ/WW coupling and, thus, cannot be detected in \epem\to Z\h (Higgs-strahlung) or \nu\anti\nu \h (via WWWW fusion). Despite sum rules which ensure that the light \h must have significant t\anti t or b\anti b coupling, for a wedge of moderate \tanb, that becomes increasingly large as \mh increases, the \h can also escape discovery in both b\anti b \h and t\anti t \h production at a \rts=500-800\gev \epem collider (for expected luminosities). If the other Higgs bosons happen to be too heavy to be produced, then no Higgs boson would be detected. We demonstrate that, despite such high masses for the other Higgs bosons, only the low-\tanb portion of the no-discovery wedges in [\mh,\tanb] parameter space can be excluded due to failure to fit precision electroweak observables. In the \tanb\gsim 1 regions of the no-discovery wedges, we find that the 2HDM fit to precision electroweak observables has small Δχ2\Delta\chi^2 relative to the best minimal one-doublet SM fit.Comment: 14 pages, 4 figures. 1st two figures have been reformatted to improve readabilit
