Principal and Mathematics Coaches\u27 Journey to Improve Mathematics Learning

My educational career path began as an elementary school teacher, then as an assistant principal, and now as a principal. With the educational experiences that I had at each level of my career, I was certain I would be able to handle an increase in the mathematical rigor presented to our students through the new Mathematics Standards of Learning for Virginia Public Schools (SOL) [1]. I found that, yes, I was able to understand the rigor. However, I found the challenge was providing the needed assistance to bring about results that would ultimately help our teachers and students be successful. I knew that something was needed, but what that something was I was not sure. Fortunately, Richneck Elementary was provided a wonderful opportunity of being assigned a mathematics coach for three years by way of a grant that the Newport News Public School division was awarded to support military-connected students. In addition, the grant supported teachers to work toward their Mathematics Specialist degree. As a result, Karen Joos, Mathematics Coach, received her master\u27s in education with an endorsement as a Mathematics Specialist. David Hundley, Mathematics Coach Facilitator, provided support for coaches under this grant. This article will provide a road map for the journey: working with the mathematics coaches and understanding their processes, promoting my leadership philosophy in relation to the new rigor of the state standards, improving communication through lessons learned, and identifying the collaboration process to achieve the best results for the school and community

[Review of] Matibag, Eugenio. Haitian-Dominican Counterpoint

Those unfamiliar with the Dominican Republic and Haiti would probably think that the two countries with their different languages and cultures are distinct and separate historically as they are culturally. The French and African heritage of Haiti is often contrasted with the Spanish heritage of the Dominican Republic. Matibag demonstrates that the two cultures and nations are intertwined at a level that would surprise even the informed scholar

Poor Women with Sexually Transmitted Infections: Providers’ Perspectives on Diagnoses

This article presents results from a study of health care providers, mainly nurses and nurse practitioners, who routinely diagnose sexually transmitted diseases (STDs) in rural low-income populations in West Virginia (WV). A qualitative analysis of eighteen semi-structured interviews reveals that providers who consistently work with low-income populations believe patients undergo a negative change in self-image in response to a chronic STD diagnosis. Providers express concerns about a number of issues related to low-income, rural women’s access to sexual health care and see the need for more sexuality education, more funding for free and reduced cost clinics, and more available health insurance. Additionally, despite problems working in publicly funded clinic environments, providers attempt to eliminate stigma attached to diagnoses of sexually transmitted disease

Applied statistics: A review

The main phases of applied statistical work are discussed in general terms. The account starts with the clarification of objectives and proceeds through study design, measurement and analysis to interpretation. An attempt is made to extract some general notions.Comment: Published at http://dx.doi.org/10.1214/07-AOAS113 in the Annals of Applied Statistics (http://www.imstat.org/aoas/) by the Institute of Mathematical Statistics (http://www.imstat.org

CSM programs SM RCS propellant quantity gaging systems program

Computer program calculates actual and useable remaining propellant quantities as required in positive expulsion rocket engine propellant feed system. Program establishes relationship between helium system pressures and temperatures and propellant weight remaining in tanks. Program is written in FORTRAN 4 for IBM-360 computer

Capacitance Measurements of Defects in Solar Cells: Checking the Model Assumptions

Capacitance measurements of solar cells are able to detect minute changes in charge in the material. For that reason, capacitance is used in many methods to electrically characterize defects in the solar cell. Standard interpretations of capacitance rely on many assumptions, which, if wrong can skew the results. We explore possible alternate explanations for capacitance transitions, which may not be linked directly to defects, such as a non-ideal back contact, and series resistance

Highly linear, sensitive analog-to-digital converter

Analog-to-digital converter converts 10 volt full scale input signal into 13 bit digital output. Advantages include high sensitivity, linearity, low quantitizing error, high resistance to mechanical shock and vibration loads, and temporary data storage capabilities

Concepts and a case study for a flexible class of graphical Markov models

With graphical Markov models, one can investigate complex dependences, summarize some results of statistical analyses with graphs and use these graphs to understand implications of well-fitting models. The models have a rich history and form an area that has been intensively studied and developed in recent years. We give a brief review of the main concepts and describe in more detail a flexible subclass of models, called traceable regressions. These are sequences of joint response regressions for which regression graphs permit one to trace and thereby understand pathways of dependence. We use these methods to reanalyze and interpret data from a prospective study of child development, now known as the Mannheim Study of Children at Risk. The two related primary features concern cognitive and motor development, at the age of 4.5 and 8 years of a child. Deficits in these features form a sequence of joint responses. Several possible risks are assessed at birth of the child and when the child reached age 3 months and 2 years.Comment: 21 pages, 7 figures, 7 tables; invited, refereed chapter in a boo

Comment on ``Consistency, amplitudes and probabilities in quantum theory'' by A. Caticha

A carefully written paper by A. Caticha [Phys. Rev. A57, 1572 (1998)] applies consistency arguments to derive the quantum mechanical rules for compounding probability amplitudes in much the same way as earlier work by the present author [J. Math. Phys. 29, 398 (1988) and Int. J. Theor. Phys. 27, 543 (1998)]. These works are examined together to find the minimal assumptions needed to obtain the most general results
