The educational achievement distribution of Israeli students is characterized by a low level of achievement with a wide achievement gap between high and low achievers compared with the Organisation for Economic Co-operation and Development (OECD average. In fact, Israeli student achievement is characterized by the widest gap among the OECD…

The purpose of this research was to investigate the role of school district expenditures in predicting student achievement in Ohio for the school year 2009-2010. Building upon the concept of the "65 percent solution," the research questions that guided this study were: (1) What percentage of Ohio's school district's operating…

Although there exists a large body of research concerning the relationship between expenditure and student achievement, a lack of research exists analyzing this relationship as it pertains specifically to students with disabilities. Given the increasing fiscal and academic pressures districts face to allocate resources efficiently, the purpose of…

Educators face increasing demands to raise student achievement, to improve classroom instruction, and to demonstrate accountability in an environment of high stakes testing. However, meeting these demands is challenging in the face of numerous risk factors that jeopardize the academic success of elementary and secondary students. To that end, the…

The K-12 student population is becoming increasingly diverse in the United States. In particular, the number of English Language Learners (ELLs) rose from 4.7 million in 1980 to 11.2 million in 2009, more than doubling from 10% to 21% of the student population (U.S. Department of Education n.d.). At approximately 1.8 million, the state of…

In most school achievement research, the relationships between achievement and explanatory variables follow the Newton and Einstein concept/principle and the viewpoint of the macro-observer: Deterministic measures based on the mean value of a sufficiently large number of schools. What if the relationships between achievement and explanatory…

One of the most influential studies affecting educational policy is Glass and Smith's 1978 study, "Meta-Analysis of Research on the Relationship of Class-Size and Achievement." Since its publication, educational policymakers have referenced it frequently as the justification for reducing class size. While teachers and the public had long believed…

Class size may be important in achievement, but it is not the only decision for policymakers. Class size plays a role, but the role is effectively fulfilled only when the other players are successful. Therefore, it is appropriate to address several questions: What goals are to be accomplished; what is the best distribution of personnel related to…

The previous articles on class size and other productivity research paint a complex and confusing picture of the relationship between policy variables and student achievement. Missing is a conceptual scheme capable of combining the seemingly unrelated research and dissimilar estimates of effect size into a unified structure for policy analysis and…

This article focuses on a method of policy analysis that has evolved from the previous articles in this issue. The first section, "Toward a Theory of Educational Production," identifies concepts from science and achievement production to be incorporated into this policy analysis method. Building on Kuhn's (1970) discussion regarding paradigms, the…

The author believes that a unified theory might provide ideas helpful for improving research; professional training and practice; and therefore, student achievement. Little attention was paid to how several variables might work together and there is little discussion regarding how they might work together. The author stresses that there are…

Combining explanatory variables into factors instead of using individual variables in an achievement production function is advocated in several of the articles in this special issue. This article provides a brief overview of factor analysis explaining and illustrating the reasoning for this technique. There is a linchpin: Factor analysis is an…

Elementary and secondary students can be impacted by a number of risk factors, all of which can have a negative influence on their academic success. To that end, the identification of risk factors is an important first step in closing achievement gaps. For example, clear evidence of an achievement gap can be found in Indiana's high school…

What distinguishes successful schools from unsuccessful schools? This question has relevance for the practice of educational leadership as well as the preparation of leaders. Successful schools are led by principals who set the direction and influence student learning, and who change the instructional process by focusing deliberately on teaching…

Principals in urban settings serve elementary schools often densely populated with highly mobile, ethnically diverse, and economically disadvantaged students. Due to the changing landscape of increasing accountability issues required by the "No Child Left Behind Act (NCLB)" (2001), principals must adjust the mission of the school community to meet…
