Reality Check: Edupreneurs, “Tech-based Solutions” & Misguided Innovation

Elementary and secondary schooling, regardless of sector – public, publicly authorized and financed charter, or private – remains a human resource intensive industry.  Quality schooling requires sufficient numbers of sufficiently trained teachers, support staff, administrators and others to get the job done.  There must be enough of them and they must be sufficiently compensated to attract quality candidates into the field.

The share of school spending allotted to salaries and benefits of employees has been remarkably stable over time, at about 81% (Figure 10). The share allocated to employee benefits has climbed (about 6%) and has been offset by a commensurate decline in the share allocated to salaries and wages.

Reformers and edupreneurs[i] have spent decades diddling around the edges of education systems pursuing the ultimate technological innovations. In the broad sense, technological innovation for improving productivity and efficiency refers to any change in the way things are done – the organization and deployment of staff, delivery of programs, use of materials, supplies, etc. where those changes are brought about by introduction of some new technology – as simple as pens and pencils replacing slate tablets. The idea is that the introduction of new technology and resulting change in the way things get done, leads to improved efficiency – lower cost of getting the same outcomes, or same cost of getting even better outcomes!  An extension of this concept, “Disruptive Innovation” refers to major shifts in the way things are done. Critics of public education systems assert that disruptive innovation is needed to completely overhaul our stagnant, costly, inefficient and failing system.

Modern edupreneurs and disrupters seem to have taken a narrow view of technological substitution and innovation, equating technology almost exclusively with laptop and tablet computers – screen time – as potential replacements for teachers – whether in the form of online schooling in its entirety, or on a course by course basis (unbundled schooling).[ii] For example, the often touted Rocketship model (a chain of charter schools), makes extensive use of learning lab time in which groups of 50 to 70 (or more) students work on laptops while supervised by uncertified “instructional lab specialists.”[iii] Fully online charter schools have expanded in many states often operated as for-profit entities.[iv] The overarching theme is that there must be some way to reduce the dependence on human resources to provide equal or better schooling, because human resources are an ongoing, inefficient expense.

In 2011, on the invitation of New York State Commissioner of Education John King (later, replacement of Arne Duncan as U.S. Secretary of Education), Marguerite Roza, at the time a Senior Economic and Data Advisor to the Bill & Melinda Gates Foundation,[v] presented the Productivity Curve illustration (Figure 11) at a research symposium of the New York State Board of Regents.[vi] Roza used her graph to assert that, for example, for $20,000 per pupil, tech-based learning systems could provide nearly 4x the bang for the buck as the status quo, and double the bang for the buck as merely investing in improved teacher effectiveness.

The most significant shortcoming of this graph, however, was that it was entirely speculative[vii] (actually, totally made up! Fictional!) – a) not based on any actual empirical evidence that such affects could be or have anywhere been achieved, b) lacking any definition whatsoever as to what was meant by “tech-based learning systems” or “improve teacher effectiveness”, and c) lacking any information on the expenditures or costs which might be associated with either the status quo or the proposed innovations. That is, without any attention to the cost effectiveness frameworks I laid out in the previous chapter. The graph itself was then taken on the road by Commissioner King and used in his presentations to district superintendents throughout the state![viii]

In a comprehensive review of literature on the state of charter schooling in the U.S., including online charter schooling, authors Epple, Romano and Zimmer paint a rather ugly picture of the outcomes achieved by fully online “cyber” charter schools, noting: “online ‘cyber’ schools appear to be a failed innovation, delivering markedly poorer achievement outcomes than TPSs.”[ix] (p. 55) Perhaps we just haven’t figured out yet how to most effectively and efficiently deploy mass substitution of human resources with computing technology. Or, perhaps, such mass substitution simply isn’t productive. Most disturbingly, expansion of these alternatives has not been accompanied by serious efficiency or cost effectiveness analysis. Indeed it’s possible that the outcome reductions measured are consistent with the associated expenditure reductions, thus a break-even on efficiency.

That is, doing less for less.

[vii] Note that the lines in the graph are actually drawn in, and not graphed from data. Also, the lines imply that at $5,000 per pupil expenditure, regardless of approach – status quo, improved teacher effectiveness, or tech-based solutions, nothing can be accomplished, though it is unclear whether the Y-axis represents an absolute standard, or change, or relative to what?

Bruce Baker is an Professor in the Graduate School of Education at Rutgers, The State University of New Jersey. From 1997 to 2008 he was a professor at the University of Kansas in Lawrence, KS. He is lead author with Preston Green (Penn State University) and Craig Richards (Teachers College, Columbia University) of Financing Education Systems, a graduate level textbook on school finance policy published by Merrill/Prentice-Hall. Professor Baker has written a multitude of peer reviewed research articles on state school finance policy, teacher labor markets, school leadership labor markets and higher education finance and policy. His recent work has focused on measuring cost variations associated with schooling contexts and student population characteristics, including ways to better design state school finance policies and local district allocation formulas (including Weighted Student Funding) for better meeting the needs of students. Baker, along with Preston Green of Penn State University are co-authors of the chapter on Conceptions of Equity in the recently released Handbook of Research Education Finance and Policy, and co-authors of the chapter on the Politics of Education Finance in the Handbook of Education Politics and Policy and co-authors of the chapter on School Finance in the Handbook of Education Policy of the American Educational Research Association. Professor Baker has also consulted for state legislatures, boards of education and other organizations on education policy and school finance issues and has testified in state school finance litigation in Kansas, Missouri and Arizona. He is a member of the Think Tank Review Panel, a group of academic researchers who conduct technical reviews of publicly released think tank reports on education policy issues.
