    STANDARDS-BASED GRADING AT THE SECONDARY LEVEL: A PHENOMENOLOGICAL STUDY OF DISTRICT LEVEL ADMINISTRATORS AND THEIR PERCEPTIONS OF TRANSITIONING FROM A TRADITIONAL GRADING SYSTEM

    Get PDF
    Traditional grading practices have been in place for well over a hundred years and grades received served to identify in which subjects a student is “smart” or in which ones they are not (Dewitt, 2017). The problem with traditional grading is that it does not provide qualitative information on the difference between an A, B, C, D, or F (Scriffiny, 2008). Standards-based grading allows the communication of where a student is in relation to well-defined standards. The problem is that many schools do not implement a standards-based grading and reporting system at the secondary level. This is in light of our nation and New York State having made considerable efforts and changes to establish well-defined standards. Although there is a misalignment in our grading practices, an overwhelming majority of our schools continue to use a traditional grading and reporting system to communicate student learning at the secondary level. As movement to a standards-based model has been noted at the primary grades, the purpose of this study is to identify the extent to which district level administrators are willing to change from a traditional grading system to a standards-based grading and reporting method at the secondary level. More specifically, this research attempted to discover the views of superintendents and assistant superintendents in changing from a traditional grading and reporting system to a standards based grading model at the secondary level. Unveiling the perceived impediments to implementing a SBG system at the secondary level was done by focusing on districts that have not implemented SBG at the secondary level and currently have a traditional grading model. To conduct this study, the researcher used a qualitative approach by conducting semi-structured exploratory interviews. Participants in the study were certified public school superintendents and assistant superintendents currently employed in a New York public high school (non-charter) in two suburban New York State counties. The selected population was presented with interview questions aimed at determining general background information as it relates to grading, if it is believed that standards-based grading is important at the secondary level, how district level administrators would make a change from a traditional model to a standards-based model, and what, if any, barriers and challenges exist in making such a change

    Learning lessons from the Ringaskiddy incineration story

    The inclusion of incineration in waste management policies has proven very contentious in the Republic of Ireland. Even though the Cork Region Waste Management Strategy (1995-2020) acknowledged the role of incineration it came as no surprise that a planning application in May 2001 by Indaver Ireland for two incinerators in Cork Harbour was met with fierce local opposition. This paper tells the story which unfolded from May 2001 to May 2007 and examines the roles played by public bodies such as Cork County Council, An Bord Pleanála, the Environmental Protection Agency and the Health and Safety Authority. The Indaver case reveals flaws in the planning process and highlights the need for a more coordinated approach which fosters trust, credibility and legitimacy

    Structural Design Optimisation Using Genetic Algorithms and Neural Networks

    This paper relates to the optimisation of structural design using Genetic Algorithms (GAs) and presents an improved method for determining the fitness of genetic codes that represent possible design solutions. Two significant problems that often hinder design optimisation using genetic algorithms are expensive fitness evaluation and high epistasis. Expensive fitness evaluation results in slow evolution and occurs when it is computationally expensive to test the effectiveness of possible design solutions using an objective function. High epistasis occurs when certain genes lose their significance or value when other genes change. Consequently, when a fit genetic code has an important gene changed this can have a dramatic effect on the fitness of that genetic code. Often the reduction in fitness results in failure of the genetic code being selected for reproduction and inclusion in the next generation. This loss of evolved genetic information can result in the solution taking considerable time to discover
