Purpose This paper is one of seven in this volume that aims to elaborate different approaches to quality improvement in education. It delineates a methodology called Lean for Education. Design/methodology/approach The paper presents the origins, theoretical foundations, core concepts and a case study demonstrating an application in US education, specifically dealing with the problem of improving technology supports and services for instructional purposes in a school district system. Findings An approach borrowed from manufacturing, Lean is aimed at creating and delivering the greatest value to the clients or “customers” in education systems while consuming the fewest resources and eliminating waste. Simultaneously, the method engages the organization in continuous problem solving, learning and making quality improvements with Plan-Do-Check-Act cycles. The core concepts that organize the Lean for Education approach are: continuous improvement and respect for people (Emiliani, 2005). Originality/value Few theoretical treatments and demonstration cases are currently available on commonly used models of quality improvement in other fields that might have potential value in improving education systems internationally, such as large grade kindergarten-to-12 education systems in the USA. This paper fills this gap by elucidating one promising approach. The paper also derives value as it permits a comparison of the Lean for Education method with other quality improvement approaches treated in this volume.

Purpose This paper is second of seven in this volume elaborating different approaches to quality improvement in education. It delineates a methodology called design-based implementation research (DBIR). The approach used in this paper is aimed at iteratively improving the quality of classroom teaching and learning practices in defined problem areas through collaborations among researchers, practitioners and other education stakeholders. Design/methodology/approach The paper describes the origins of the approach in US education, along with its foundations, core principles and a case application of DBIR in practice. The case focuses on the specific problem of teaching science and genetics in primary and secondary schools in a district. Findings The guiding principles of DBIR are: a focus on persistent problems of classroom educational practice; iterative and collaborative design and testing of innovations through partnerships between researchers and practitioners, involving multiple stakeholders’ perspectives; a concern with developing theory related to both implementation processes and classroom learning outcomes, using systematic inquiry; and development of the capacity of both researchers and practitioners to sustain changes in educational systems. Originality/value Few theoretical treatments and demonstration cases are currently available in US education that examine common models of quality improvement, particularly DBIR. By engaging practitioners with researchers in designing, testing and implementing reforms meaningfully, DBIR shows promise in offering significant on-the-ground benefits. This paper adds value by allowing readers to compare the DBIR method with the other improvement approaches explicated in this volume.

Purpose This paper is one of seven in this volume, each elaborating different approaches to quality improvement in education. The purpose of this paper is to delineate a methodology called positive deviance. Design/methodology/approach The paper presents the origins, theoretical foundations, core principles and a case study demonstrating an application of positive deviance in US education, specifically dealing with the problem of high school dropout prevention in a California school district. Findings The six phases of this “asset-based” improvement approach are: define the organizational or community problem and desired outcomes; determine common practices relevant to the problem; discover uncommon but successful behaviors and strategies that solve the problem (the positive deviants), through inquiry and observation; design an action learning initiative based on findings; discern (monitor) progress of the initiative by documenting and evaluating regularly; and disseminate results through sharing, honoring and amplifying success stories. Originality/value Few theoretical treatments and demonstration cases are currently available on commonly used models of quality improvement from business, manufacturing and other fields that have potential value in improving education systems internationally. This paper fills this gap by elucidating one promising approach. By facilitating a comparison of the positive deviance approach to other quality improvement approaches treated in this volume, the paper provides added value.

Purpose This paper is one of seven in this volume that aims to elaborate different approaches to quality improvement in education. It delineates a methodology called Six Sigma. Design/methodology/approach The paper presents the origins, theoretical foundations, core principles and a case study demonstrating an application of Six Sigma in a school-community partnership in Milwaukee, Wisconsin. Findings The core principles underlying the approach are decreasing variability or unreliability in organizational work processes, eliminate waste or activity that does not add value to desired outcomes, identify defects and decrease their incidence, reduce the cost of work processes, and improve beneficiary/client satisfaction levels. The steps in this statistics-dependent method are design, measure, analyze, improve and control. Originality/value Few theoretical treatments and demonstration cases are currently available on commonly used models of quality improvement that might have potential value in improving education systems internationally. This paper fills this gap by elucidating one promising approach. The paper also derives value as it permits a comparison of the Six Sigma approach with other quality improvement approaches treated in this volume.

Purpose The purpose of this paper is to delineate an approach to quality assurance in education called networked improvement communities (NICs) that focused on integrating the methodologies of improvement science with few of the networks. Quality improvement, the science and practice of continuously improving programs, practices, processes, products and services within organized social systems, is a still-evolving area in education. This paper is the first of seven elaborating upon different approaches to quality improvement in education[1]. It delineates a new methodology called the NICs model. Developed by the Carnegie Foundation for the Advancement of Teaching, the approach is aimed at continuously improving the quality of practices, processes and outcomes in targeted problem areas in education systems. Design/methodology/approach The paper presents the historical development, theoretical foundations, core principles and adaptation of key elements of the NICs model for quality improvement in education. A case study specifically examines the problem of fostering new teacher effectiveness and retention in large public school systems in the USA. Findings The six principles underlying the NICs model are as follows: make the work problem-specific and user-centered, focus on variation in performance, see the system that produces outcomes, improve at scale what you can measure, use disciplined inquiry to drive improvement and accelerate learning through networked communities. Originality/value Few theoretical treatments and demonstration cases are currently available that examine the application of common models of quality improvement in education. This paper elaborates on one promising approach. In addition to examining the NICs model, the paper derives added value by allowing comparisons with seven widely used quality improvement approaches treated in this volume.
