The Impact of a Community College Teacher Education Program on the Success Rate of Minority Teacher Certification Students

The Impact of a Community College Teacher Education Program on the Success Rate of Minority Teacher Certification Students

Date: May 2013
Creator: Perkins, Britine Lynee
Description: The relationship between the mission of community colleges and the increasing teacher shortage has become more transparent as many community colleges have implemented teacher education programs to address community needs, the shortage of qualified teachers, and the lack of diversity among teachers. As the community college's teacher education role has increased, many community colleges have responded by adding associate of arts degrees and certificate programs specific to teacher education to tackle the shortage of teachers and the lack of diversity among teachers in the nation's classrooms. The purpose of this study was to examine the effectiveness of one community college's pre-service teacher education program in transferring minority students to a university teacher education program and the likelihood of the students graduating with both bachelor's degrees and teacher certification. This longitudinal ex post facto causal-comparative mixed methods case study involved tracking a cohort of minority students over a 6-year period. Data were gathered from existing teacher education program records for native and transfer students at one community college and two four-year institutions. Unstructured interviews were conducted with administrators over the community college's program. For data analysis, ?2 and Phi Coefficients were conducted to compare the minority students' university transfer and graduation ...

The Relationship of Anxiety to Critical Thinking

The Relationship of Anxiety to Critical Thinking

Date: August 1971
Creator: Perkins, Fredda M.
Description: Anxiety increase drive level and will at first lead to an increased level of performance and then, as drive level continues to rise, to a decrease in performance. There seems to be an optimal level condition for best performance. On either side of this point, performance is relatively impaired. However, nothing has been done to explore directly its relationship to critical thinking ability. The purpose of this study was to investigate that relationship.

Expanded Perceptions of Identity in Benjamin Britten's Nocturne, Op. 60

Expanded Perceptions of Identity in Benjamin Britten's Nocturne, Op. 60

Date: May 2008
Creator: Perkins, Anna Grace
Description: A concentrated reading of Benjamin Britten's Nocturne through details of the composer's biography can lead to new perspectives on the composer's identity. The method employed broadens current understandings of Britten's personality and its relationship to the music. After creating a context for this kind of work within Britten scholarship, each chapter explores a specific aspect of Britten's identity through the individual songs of the Nocturne. Chapter 2 focuses on how Britten used genres in a pastoral style to create his own British identity. Chapter 3 concentrates on the complex relationship between Britten's homosexuality and his pacifism. Chapter 4 aims to achieve a deeper understanding of Britten's idealization of innocence. The various aspects of Britten's personality are related to one another in the Conclusion.

Icing Frequencies Experienced During Climb and Descent by Fighter-Interceptor Aircraft

Icing Frequencies Experienced During Climb and Descent by Fighter-Interceptor Aircraft

Date: July 1, 1958
Creator: Perkins, Porter J.
Description: Data and analyses are presented on the relative frequencies of occurrence and severity of icing cloud layers encountered by jet aircraft in the climb and descent phases of flights to high altitudes. Fighter-interceptor aircraft operated by the Air Defense Command (USAF) at bases in the Duluth and Seattle areas collected the data with icing meters installed for a l-year period. The project was part of an extensive program conducted by the NACA to collect Icing cloud data for evaluating the icing problem relevant to routine operations. The average frequency of occurrence of icing was found to be about 5 percent of the number of climbs and descents during 1 year of operations The icing encounters were predominantly in the low and middle cloud layers, decreasing above 15,000 feet to practically none above 25,000 feet. The greatest thickness of ice that would accumulate on any aircraft component (as indicated by the accretion on a small object) was measured with the icing meters. The ice thicknesses on a small sensing probe averaged less than 1/32 inch and did not exceed 1/2 inch. Such accumulations are relatively small when compared with those that can form during horizontal flight in icing clouds. The light ...

Preliminary Survey of Icing Conditions Measured During Routine Transcontinental Airline Operation

Preliminary Survey of Icing Conditions Measured During Routine Transcontinental Airline Operation

Date: December 16, 1952
Creator: Perkins, Porter J.
Description: Icing data collected on routine operations by four DC-4-type aircraft equipped with NACA pressure-type icing-rate meters are presented as preliminary information obtained from a statistical icing data program sponsored by the NACA with the cooperation of many airline companies and the United States Air Force. The program is continuing on a much greater scale to provide large quantities of data from many air routes in the United States and overseas. Areas not covered by established air routes are also being included in the survey. The four aircraft which collected the data presented in this report were operated by United Air Lines over a transcontinental route from January through May, 1951. An analysis of the pressure-type icing-rate meter was satisfactory for collecting statistical data during routine operations. Data obtained on routine flight icing encounters from.these four instrumented aircraft, although insufficient for a conclusive statistical analysis, provide a greater quantity and considerably more realistic information than that obtained from random research flights. A summary of statistical data will be published when the information obtained daring the 1951-52 icing season and that to be obtained during the 1952-53 season can be analyzed and assembled. The 1951-52 data already analyzed indicate that the quantity, ...

Flight Instrument for Measurement of Liquid-Water Content in Clouds at Temperatures Above and Below Freezing

Flight Instrument for Measurement of Liquid-Water Content in Clouds at Temperatures Above and Below Freezing

Date: March 5, 1951
Creator: Perkins, Porter J.
Description: A principle formerly used in an instrument for cloud detection was further investigated to provide a simple and rapid means for measuring the liquid-water content of clouds at temperatures above and below freezing. The instrument consists of a small cylindrical element so operated at high surface temperatures that the impingement of cloud droplets creates a significant drop in the surface temperature. ? The instrument is sensitive to a wide range of liquid-water content and was calibrated at one set of fixed conditions against rotating multicylinder measurements. The limited conditions of the calibration Included an air temperature of 20 F, an air velocity of 175 miles per hour, and a surface temperature in clear air of 475 F. The results obtained from experiments conducted with the instrument indicate that the principle can be used for measurements in clouds at temperatures above and below freezing. Calibrations for ranges of airspeed, air temperature, and air density will be necessary to adapt the Instrument for general flight use.
