    A Two-Step Approach to Diagnostic Assessment in College Math, Fall 2007

    This study examines a modified strategy for diagnostic testing and its use as a predictor of performance in college math. A study conducted in 2005 analyzed the results of a single diagnostic test given at the beginning of first semester to all students in the School of Manufacturing Sciences post-secondary programs at Fanshawe College. The range of topics covered by this single test was comprehensive. The attempt to find correlation between the results of this test and grade outcomes in first semester college technology math was inconclusive. The current study examines the results of a system of two similar tests, administered to students of the 2007 Fall intake of the same school. The first of the two tests was given during the first mathematics class of the semester; the second test after approximately two weeks of the semester. The content of the first test was reviewed during lectures in the intervening two week period so that student progress could be gauged with respect to results from the first assessment. The results of the combined diagnostic test results provide a more effective predictive tool than the results from the 2005 study. Specifically, the findings of this study show that 67.9% of students who failed the diagnostic tests (combined mark) failed first semester mathematics in the Fall of 2007. The current study and the 2005 study show that both grade 11 and 12 mathematics courses have a significant effect on performance in first semester college mathematics. The pathway MBF3C–MAP4C (11C-12C) is the most common pathway chosen by first semester entrants and further, this pathway is insufficient preparation for first semester college technology mathematics of post-secondary programs offered by the School of Manufacturing Sciences. This study finds that an overwhelming number of students who took the applied stream mathematics course in grade 10 pursued the pathway MBF3C-MAP4C. Students who chose an alternate pathway culminating in the grade 12C course, MAP4C, fared much better in first semester technology mathematics, suggesting that the choice of grade 11 mathematics course has the greater impact on success in college mathematics. Both this study and the previous study show that all students who had taken Mathematics for College Technology in grade 12 (MCT4C) passed first semester college technology mathematics in the School of Manufacturing Sciences post-secondary programs in the Fall of 2005 and 2007

    A Study of the Level of Math Preparedness of Manufacturing Sciences Students in the Fall Semester of 2005

    The main objective of this study was to gauge preparedness in math with achievement in first semester math for the fall 2005 intake of Manufacturing Sciences Division Post-Secondary program students. he data used to measure this level of preparedness was gleaned from students’ high school grade 12 (new and old curriculum) or OAC math marks and the results of a diagnostic test given to students during the first week of the fall semester. In addition, success in first semester math was analyzed in relation to the specific high school math course taken. The results of this study demonstrate that high school math marks alone are a poor predictor of performance in first semester math. In addition, students emerging from the new curriculum grade 12 Math for College and Apprenticeship (MAP4C) failed first semester math at nearly three times the rate of all other course groupings combined. Conversely, students emerging from any of the University stream high school Grade 12 math courses or the College stream Math for Technology (MCT4C) were best prepared for college math in Manufacturing Sciences Division Post-Secondary programs. The diagnostic test marks were not a reliable predictor of individual student success (or “at risk” behaviour) in first semester. However, students falling into the fortieth percentile or lower groupings on the test showed a marked increase in tendency towards “at risk” behaviour or failure. Technician stream students as a group exhibited a failure rate that was double that of the technology stream group. It is recommended that the administration of the diagnostic test be continued by the college and that tracking of these indicators be carried out annually in order to monitor these trends. In addition it is recommended that students at the high school level are made aware of the need to take Grade 12 Math for Technology (MCT4C) as a minimum preparation for success in Manufacturing Sciences Division math courses. The questions raised in this study concerning differences in performance according to gender and stream warrant further study

    Energy Storage Roadmap for Northeast Ohio 2019: Executive Summary

    Get PDF
    A great deal has changed in the energy storage industry since 2011. The way in which people interact with energy in living our lives has continued to undergo fundamental shifts that have become ever more conspicuous. The changing dynamics of not only how the energy we use is generated, but also of how and when it must be deployed to meet our increasing—and increasingly complex—demand for electric power are accelerating the need for more advanced, economical forms of energy storage. This 2019 Energy Storage Roadmap examines the trends that are driving growth in energy storage for the electric power grid, transportation, and consumer electronics applications. The report also highlights the commercial and structural assets that Northeast Ohio currently possesses that could enable it to capture an increasing share of what is projected to be a $100 billion market by 2025. While disruptive market forces are causing the ground to shift for the advanced energy industry, this shift will present opportunities for Northeast Ohio to capitalize on innovative technologies being developed regionally that would enable the realization of appreciably greater economic growth. This 2019 Roadmap provides a background on Energy Storage technologies and the role the region currently plays in their development. The Roadmap also provides a vision for how existing local assets can be leveraged in conjunction with funding opportunities for technology innovation to capture a larger share of this high-growth market. The goal of the 2019 Roadmap is to propose how assets and strategies that can be together deployed to establish the region as an energy storage activity hub
