In particular, I show how the bias-variance tradeoff from machine learning can be formally generalized to be applicable to several prominent educational debates, including debates around learning theories (cognitivist vs. situativist and constructivist theories) and pedagogy (direct instruction vs. discovery learning). I then look to see how various data science techniques that have been proposed to navigate the bias-variance tradeoff can yield insights for productively navigating these educational debates going forward.  \nKeywords: bias-variance tradeoff, learning theories, direct instruction, discovery learning, research methods, epistemology, artificial intelligence, machine learning  \nIntroduction  \nIn recent years, data science and machine learning have been used to make sense of various forms of educational data. Educational data science can enhance our understanding of learning and teaching; give insights to teachers, students, and administrators about learning happening in the classroom; and lead to the creation of data-driven adaptive learning systems. However, I claim that machine learning and data science have more to offer than a set of techniques that can be applied to educational data. Theoretical conceptsand principles in machine learning can provide broader insights to education research. In particular, in this article, Ishow that the bias-variance tradeoff from machine learning can provide a new lens with which to view prominent educational debates.  \nThe field of education is filled with seemingly perennial debates that have important implications on the nature of education research and practice. These debates span epistemology (e.g., positivism vs. constructivism), ontology (e.g., cognitive vs. situative theories of learning), methodology (e.g., quantitative vs. qualitative), and pedagogy (e.g., direct instruction vs. discovery learning) . Interestingly, many researchers have contended that these debates are often premised on false dichotomies and admit that a moderate position is more warranted (Alfieri et al., 2011; A. L. Brown & Campione, 1994; Cobb, 2007; Doroudi et al., 2020; Greeno, 2015; Johnson & Onwuegbuzie, 2004; Kersh & Wittrock, 1962; Shaffer, 2017; Shaffer & Serlin, 2004; Tobias & Duffy, 2009), yet these debates persist and many researchers still seem to favor one side over the other, resulting in somewhat  \nisolated research communities that speak past each other (if they speak to each other at all; Jacobson et al., 2016) .  \nIn this article, I show that the bias-variance tradeoff can be formally generalized to help explain the nature of these debates in the education literature. I first introduce the biasvariance tradeoff and how it is used in statistics and machine learning. I then describe a formal generalization of the biasvariance decomposition and map this generalized version to debates around theories of learning, methodology, and pedagogy, while also showing how these tradeoffs are rooted in similar debates in the history of artificial intelligence (AI) . While the first two sections that introduce and formalize the bias-variance tradeoff are somewhat technical, later sections of the article primarily make descriptive claims and use representative quotations from prominent researchers in these debates. As such, the article aims to be accessible to and of interest to both quantita","cbCaivNraH0KfhZK","https://ap.wps.com/l/cbCaivNraH0KfhZK","pdf",920638,18,"English","# Introduction\n## Educational debates and the proposed lens\n# The bias-variance tradeoff and formal generalization\n## Mapping to learning theories, methodology, and pedagogy\n# Navigating tradeoffs with data-science techniques\n## Implications for epistemology and ongoing debates","[{\"question\":\"What is the central idea of the article?\",\"answer\":\"It claims that the machine-learning bias-variance tradeoff can be generalized to provide insights for prominent educational debates beyond using data science only as a technical toolbox.\"},{\"question\":\"Which educational debates are addressed?\",\"answer\":\"The article maps the tradeoff to debates around learning theories (cognitivist vs. situativist/constructivist), pedagogy (direct instruction vs. discovery learning), and broader issues including epistemology, ontology, and methodology.\"},{\"question\":\"How does the article propose navigating these debates?\",\"answer\":\"By using data-science and machine-learning techniques that have been proposed to manage the bias-variance tradeoff, it derives guidance on how to engage the corresponding educational disagreements more productively.\"}]","The Bias-Variance Tradeoff: How Data Science Can Inform Educational Debates - Research article summary | PDF",1792068617,45]
