Summarizing data derived from a four-year combined longitudinal/ cross-sectional comparative study of the implementation of one standards-based middle school curriculum program, Mathematics in Context, this book demonstrates the challenges of conducting comparative longitudinal research in the reality of school life.
The study was designed to answer three questions:
The researchers examined a range of variables that affected data collection. These variations highlight the need to study the effects of the culture in which student learning is situated when analyzing the impact of standards-based curricula on student achievement.
This book is directed to educational researchers interested in curriculum implementation, mathematics educators interested in the effects of using reform curriculum materials in classrooms, evaluators and research methodologists interested in structural modeling and scaling of instructional variables, and educational policy makers concerned about reform efforts.
Deep Impact, or at least part of the flight system, is designed to crash into comet 9P/Tempel 1. This bold mission design enables cometary researchers to peer into the cometary nucleus, analyzing the excavated material with its imagers and spectrometers. The book describes the mission, its objectives, expected results, payload, and data products in articles written by those most closely involved. This mission has the potential of revolutionizing our understanding of the cometary nucleus.
The book presents theoretical and empirical research on the integrated assessment of cartels' effects on national economies. The empirical analysis is based on three cases in Lithuania, a country chosen because it corresponds to the features of a small economy with a developing culture of competition. An integrated assessment of a cartel's impact by measuring the net economic effect created by its operations on the market is extremely important at the scale of national economies. If a cartel's true impact is not identified and evaluated, it is impossible to make important strategic decisions, for the whole economy instead of individual affected parties, and to establish an optimum baseline for mitigating the harm done to the economy. Thus, an integrated cartel impact assessment can help to more proactively combat cartel agreements on the market and improve the economic welfare of the respective country.
