FREE KINDLE W/ BOOK PURCHASE PRINCIPAL LEADERSHIP AND STUDENT ACHIEVEMENT...RESEARCH IN NEW JERSEY URBAN HIGH SCHOOL DISTRICTS By Dr. Janet A. Munger WITHOUT LEADERSHIP, THERE IS NO SUCCESS My research clearly demonstrates positively and significantly that principal leadership effectiveness relates to school productivity: student achievement, school retention rate and educational continuance rate. The manner in which the school principal influences student achievement is determined. The link between the internal school structure and the external school environment is established. It has been determined from reviewing current research that limited attention has been paid to the methodology of collecting research data. Reviews of research since the 1950s and 1960s have charted intellectual progress. From national and international reviews, it has been brought to light that there exists the tendency in research publications to omit pertinent information pertaining to the rationale of the study; methods of data collection; the extraction of data; its evaluation and analysis; and the explanation of how this has impacted the interpretation of the research findings. As evidenced, improvement is needed in setting research studies within conceptual frameworks and in applying proper analytical procedures in examining combinations of variables. Explanatory Framework My research is set within an explanatory framework. It is based on theory and the desire to increase our understanding of school process. Proper analytical procedures are employed in examining sets of variables. The rationale of the study; methods of data collection; extraction of data; lengthy descriptions and interpretations of how this has impacted its interpretation are presented in my research study in great detail. It is supported by my real-life experiences from over 40 years in educational administration and teaching. Organizational Leadership: Importance Its presentation of the historical development of the literature from 1900 provides a rich background study in the field of organizational leadership. The strength of the data collection procedures, data extraction methodology, analytical methods employed, and research findings serve as a model for future researchers and graduate students of leadership effectiveness and school productivity. It is a syllabus for graduate study in educational administration and school leadership. It is needed in the professional development training of school principals, school leaders, and teachers. It is imperative that these research determinations are employed by educators and administrators alike if we are to increase our understanding of leadership effectiveness and school productivity, inclusive of student achievement. Those variables determined to contribute to leadership effectiveness as it relates to school productivity, culled from hundreds of research studies, are subsumed within my research manuscript. Those effective school leader determinations, compiled from the study of hundreds of research studies over the past century and the expenditure of millions of dollars are found in this manuscript--my doctoral research study. The relationship between leadership effectiveness and school productivity is established. It is strong, positive, and significant. Those factors contributing to the differences in leadership effectiveness and school productivity are summarized, analyzed, and discussed in great detail. Higher Education is a multi-million-dollar industry in consulting services. The cost of customizing leadership development programs from top business schools can cost $150,000 per person. This Leadership Research Will Serve to Fill This Need in Our Global Economy.
