	~~'''Adaptive expertise'''~~ is a broad construct that encompasses a range of [[cognitive]], motivational, and personality-related components, as well as [[habits of mind]] and [[disposition]]s. Generally, problem-solvers demonstrate adaptive expertise when they are able to efficiently solve previously encountered tasks and generate new procedures for new tasks.<ref name="Hatano">Hatano, G. and K. Inagaki (1986). "Two courses of expertise." Child development and education in Japan: 262–272.</ref> This definition can be contrasted with more traditional ideas of [[expertise]] popularized by ~~Chi<ref~~ name~~="Chi">Chi, M., Feltovich, P. and Glaser, R., (1981).

Its empirical validity has~~ been ~~examined in~~ a number of training and learning contexts. The term was first coined by [[Giyoo Hatano]] and [[Kayoko Inagaki]],<ref name="Hatano"/> to tease out the variability within groups of experts. To illustrate, imagine two [[sushi]] chefs: one who makes every piece perfectly but ~~routinely makes the same few types over and over (classic expertise), and one produces new menus frequently (adaptive expertise)~~. ~~To some, this is an unfair comparison,as ones~~' environment supports behavior. For example, the routine of the classic expert sushi chef may be tied to his restaurant environment, and this chef may be able to break out of the routines easily given a different situation. However, the adaptive expert chef clearly demonstrates flexible knowledge and performance of sushi-making. Learning Scientists are interested in adaptive expertise, in part because they would like to understand the types of learning trajectories that may allow practitioners break free from routines when necessary.

Bransford]] considers this flexible, innovative application of knowledge, in large part, underlies adaptive experts' greater tendency to enrich and refine their understanding on the basis of continuing experience to learn from [[problem-solving]] episodes.<ref name="Bransford"/>

	~~==A Model of Adaptive Expertise==~~
	One model of adaptive expertise<ref name="Schwartz"/> looks at two dimensions along which a learner may develop: efficiency and innovation. Classic experts are defined as being efficient when solving problems that are routine. When presented with ~~a problem that is not routine, or when transferring into a different situation, the adaptive expert may innovate.~~

	Schwartz, [[John D. Bransford\|Bransford]] and Sears<ref name="Schwartz"/> have graphically illustrated these two dimensions of expertise. On the horizontal axis, they plot efficiency of problem solving, and on the vertical axis they plot ability to innovate. In this graph, they identify four important regions: Novice (low efficiency, low innovation), Routine Expert (high efficiency, low innovation), Frustrated or Annoying Novice (low efficiency and high innovation), and Adaptive Expert (high efficiency and high innovation). As originally presented, this graph is intended as a starting point for understanding how educators should guide students' learning and trajectory to adaptive expertise. Schwartz and colleagues suggest that the trajectory, and therefore instruction, should aim for a balance of innovation and efficiency. This work is highly related to ~~their theories of [[Transfer of Learning]] and research on instruction that supports~~ transfer ~~and trajectories to adaptive expertise.~~

	~~==Trajectories to Adaptive Expertise==~~

	Schwartz and his colleagues suggest two possible trajectories to adaptive expertise 1) innovate and then become efficient or 2) become efficient and then practice innovating.<ref name="Schwartz"/> In several studies of instructional interventions,<ref>Physically Distributed Learning: Adapting and Reinterpreting Physical Environments in the Development of ~~Fraction Concepts~~. ~~Taylor Martin & Daniel L. Schwartz. Cognitive Science.[http://aaalab.stanford.edu/papers/martin_schwartz_pdl.pdf]~~<~~/ref~~><~~ref~~>~~Constructivism in an age of non-constructivist assessments. Daniel L. Schwartz, Robb Lindgren & Sarah Lewis. In T. Duffy and S. Tobias (Eds.), Constructivist instruction: Success or failure.~~ [http://aaalab.stanford.edu/papers/Constructivist_Assessments_Final.pdf]</ref> they have demonstrated that trajectory 1, innovation to efficiency, is the better developmental path. Based on this finding, these researchers have suggested that before learning procedures for solving problems, students should first be given the opportunity to innovate and attempt to discover solutions to novel problems without instruction. Following this practice with innovation, students can then benefit from routine practice, with less risk of becoming a routine expert or simply a frustrated novice.

	~~==Calculating Adaptive Expertise==~~
	Adaptive expertise is tied to the ability to transfer, that is, to apply knowledge to solving problems in a new context by recognizing the underlying similar concepts or principles that govern the given situation. A problem may be composed of factual knowledge, conceptual knowledge, and require transfer. One group<ref>Pandy, M. G., A. J. Petrosino, et al. (2004). "Assessing Adaptive Expertise in Undergraduate Biomechanics." ''[[Journal of Engineering Education]]''. 93(3): 211-222.</ref> of researchers looking specifically at the development of adaptive expertise in bioengineering operationalize adaptive expertise as the following: <math>AE=0.14F - 0.36C + 1.27T</math>, based on experimental results, but they do not yet know if these weights are generalizable.

	~~==Developing Adaptive Expertise in the Classroom==~~
	Some research has been conducted to determine when and how adaptive expertise should be developed within the elementary classroom setting. Much of the research focuses on areas of mathematics. In order to begin to cultivate adaptive expertise, Mercier and Higgins<ref name="Mercier">Mercier, E. M. & Higgins, S. E. (2013). Collaborative learning with multi-touch technology: Developing adaptive expertise. Learning and Instruction, 25, 13-23.</ref> found that students must be allowed to be innovative and exploratory with mathematical concepts. Within the context of mathematics, students should be given multiple strategies for solving a set of problems, rather than presenting one strategy for a given set. By allowing the students to explore and reflect upon the different possible math strategies, each student will choose a method that is “personal and insightful” and will help move them towards becoming more flexible and adaptive.<ref name="Verschaffel">Verschaffel, L., Luwel, K., Torbeyns, J., & Van Dooren, W. (2009). Conceptualizing, investigating, and enhancing adaptive expertise in elementary mathematics education. ~~European Journal of Psychology of Education, 24(3), 335-359~~. </~~ref> Other research found that the use of manipulatives helped to develop understanding and students were able to transfer their knowledge to new situations.<ref name="Mercier"~~/>

	Researchers have also determined that adaptive expertise can be supported by creating an environment that encourages motivation to interact with the material. Students will be motivated to succeed as they work through their misconceptions and try to obtain understanding.<ref name="Mercier"/> This environment should also be safe for students to explore while not feeling the pressure to perform at perfection.<ref name="Verschaffel"/>

	Collaboration has also been suggested to help develop adaptive expertise. As students work together in a group setting, each member discusses their individual thoughts about the concepts. As group members listen to each other’s thought and ideas, individuals are forced to reflect upon their thoughts and reconsider their viewpoints. In doing so, the students are considering the concepts at a deeper level.<ref name="Mercier"/>

	Verschaffel et al.<ref name="Verschaffel"/> explain that “adaptive expertise is not something that can be trained or taught but rather something that has to be promoted or cultivated.” They further these thoughts by suggesting that future research should be conducted over a long period of time in order to analyze the results of developing adaptive expertise.
