Learning engineering

Learning Engineering is the systematic application of evidence-based principles and methods from educational technology and the learning sciences to create engaging and effective learning experiences, support the difficulties and challenges of learners as they learn, and come to better understand learners and learning. It emphasizes the use of a human-centered design approach in conjunction with analyses of rich data sets to iteratively develop and improve those designs to address specific learning needs, opportunities, and problems, often with the help of technology. Working with subject-matter and other experts, the Learning Engineer deftly combines knowledge, tools, and techniques from a variety of technical, pedagogical, empirical, and design-based disciplines to create effective and engaging learning experiences and environments and to evaluate the resulting outcomes. While doing so, the Learning Engineer strives to generate processes and theories that afford generalization of best practices, along with new tools and infrastructures that empower others to create their own learning designs based on those best practices.
Supporting learners as they learn is complex, and design of learning experiences and support for learners usually requires interdisciplinary teams. Learning engineers themselves might specialize in designing learning experiences that unfold over time, engage the population of learners, and support their learning; automated data collection and analysis; design of learning technologies; design of learning platforms; or some combination. The products of learning engineering teams include on-line courses (e.g., a particular MOOC), software platforms for offering online courses, learning technologies (e.g., ranging from physical manipulatives to electronically-enhanced physical manipulatives to technologies for simulation or modeling to technologies for allowing immersion), after-school programs, community learning experiences, formal curricula, and more. Learning engineering teams require expertise associated with the content that learners will learn, the targeted learners themselves, the venues in which learning is expected to happen, educational practice, software engineering, and sometimes even more.
Learning engineering teams employ an iterative design process for supporting and improving learning. Initial designs are informed by findings from the learning sciences. Refinements are informed by analysis of data collected as designs are carried out in the world. Methods from learning analytics, design-based research, and rapid large-scale experimentation are used to evaluate designs, inform refinements, and keep track of iterations. According to the IEEE Standards Association's IC Industry Consortium on Learning Engineering, "Learning Engineering is a process and practice that applies the learning sciences using human-centered engineering design methodologies and data-informed decision making to support learners and their development." 
History.
Herbert Simon, a cognitive psychologist and economist, first coined the term "learning engineering" in 1967. However, associations between the two terms "learning" and "engineering" began emerging earlier, in the 1940s and as early as the 1920s. Simon argued that the social sciences, including the field of education, should be approached with the same kind of mathematical principles as other fields like physics and engineering.
Simon’s ideas about learning engineering continued to reverberate at Carnegie Mellon University, but the term did not catch on until Bror Saxberg began using it in 2014
. A clear line can be drawn from Simon to Saxberg. In 1978, Herb Simon helped bring John Anderson to Carnegie Mellon and Anderson soon began to test his theory of cognition within intelligent tutoring systems. In 1998, Carnegie Learning was spun off producing the first widespread use of intelligent tutoring systems in K12 schools. In 2004, Kenneth Koedinger and Kurt Vanlehn started the Pittsburgh Science of Learning Center, or LearnLab for short. Bror Saxberg brought his team from Kaplan to visit CMU. The team went back to Kaplan, armed with LearnLab’s KLI framework, a theoretical framework linking cognition and instruction. They began executing what we now call learning engineering to enhance, optimize, and test their educational products. Bror Saxberg would later co-write the 2014 book using the term "learning engineering". It caught on this time.
Subsequently, the term "learning engineering" has come to emphasize a focus on applied research (rather than foundational or theoretical research), as well as incorporating research findings about how people learn in order to support learning and improve real-life learning outcomes.
Overview.
Learning Engineering is aimed at addressing a deficit in the application of science and engineering methodologies to education and training. Its advocates emphasize the need to connect computing technology and generated data with the overall goal of optimizing learning environments.
Learning Engineering initiatives aim to improve educational outcomes by leveraging computing to dramatically increase the applications and effectiveness of learning science as a discipline. Digital learning platforms have generated large amounts of data which can reveal immediately actionable insights.
The Learning Engineering field has the further potential to communicate educational insights automatically available to educators. For example, learning engineering techniques have been applied to the issue of drop-out or high failure rates. Traditionally, educators and administrators have to wait until students actually withdraw from school or nearly fail their courses to accurately predict when the drop out will occur. Learning engineers are now able to use data on "off-task behavior" or "wheel spinning" to better understand student engagement and predict whether individual students are likely to fail.
This data enables educators to spot struggling students weeks or months prior to being in danger of dropping out. Proponents of Learning Engineering posit that data analytics will contribute to higher success rates and lower drop-out rates.
Learning Engineering can also assist students by providing automatic and individualized feedback.
Carnegie Learning’s tool LiveLab, for instance, employs big data to create a learning experience for each student user by, in part, identifying the causes of student mistakes. Research insights gleaned from LiveLab analyses allow teachers to see student progress in real-time.
Common approaches.
A/B Testing.
A/B testing compares two versions of a given program and allows researchers to determine which approach is most effective. In the context of Learning Engineering, platforms like TeacherASSIST and Coursera use A/B testing to determine which type of feedback is the most effective for learning outcomes.
Neil Heffernan’s work with TeacherASSIST includes hint messages from teachers that guide students toward correct answers. Heffernan’s lab runs A/B tests between teachers to determine which type of hints result in the best learning for future questions.
UpGrade is an open-source platform for A/B testing in education. It allows EdTech companies to run experiments within their own software. ETRIALS leverages ASSISTments and give scientists freedom to run experiments in authentic learning environments. Terracotta is a research platform that supports teachers' and researchers' abilities to easily run experiments in live classes.
Educational Data Mining.
Educational Data Mining involves analyzing data from student use of educational software to understand how software can improve learning for all students. Researchers in the field, such as Ryan Baker at the University of Pennsylvania, have developed models of student learning, engagement, and affect to relate them to learning outcomes.
Platform Instrumentation.
Education tech platforms link educators and students with resources to improve learning outcomes. For example, Phil Poekert at the University of Florida College of Education’s Lastinger Center for Learning has created Flamingo, a platform that integrates critical functionalities like resources and teaching management systems along with a community-based forum.
Other platforms like MATHia, Algebra Nation, LearnPlatform, coursekata, and ALEKS offer interactive learning environments created to align with key learning outcomes.
Dataset Generation.
Datasets provide the raw material that researchers use to formulate educational insights. For example, Carnegie Mellon University hosts a large volume of learning interaction data in LearnLab's DataShop. Their datasets range from sources like Intelligent Writing Tutors to Chinese tone studies to data from Carnegie Learning’s MATHia platform.
Kaggle, a hub for programmers and open source data, regularly hosts machine learning competitions. In 2019, PBS partnered with Kaggle to create the 2019 Data Science Bowl. The DataScience Bowl sought machine learning insights from researchers and developers, specifically into how digital media can better facilitate early-childhood STEM learning outcomes.
Datasets, like those hosted by Kaggle PBS and Carnegie Learning, allow researchers to gather information and derive conclusions about student outcomes. These insights help predict student performance in courses and exams.
Learning Engineering in Practice.
Combining education theory with data analytics has contributed to the development of tools that differentiate between when a student is "wheel spinning" (i.e., not mastering a skill within a set timeframe) and when they are persisting productively. Tools like ASSISTments alert teachers when students consistently fail to answer a given problem, which keeps students from tackling insurmountable obstacles, promotes effective feedback and educator intervention, and increases student engagement.
Studies have found that Learning Engineering may help students and educators to plan their studies before courses begin. For example, UC Berkeley Professor Zach Pardos uses Learning Engineering to help reduce stress for community college students matriculating into four-year institutions. Their predictive model analyzes course descriptions and offers recommendations regarding transfer credits and courses that would align with previous directions of study.
Similarly, researchers Kelli Bird and Benjamin Castlemen’s work focuses on creating an algorithm to provide automatic, personalized guidance for transfer students. The algorithm is a response to the finding that while 80 percent of community college students intend to transfer to a four-year institution, only roughly 30 percent actually do so. Such research could lead to a higher pass/fail rate and help educators know when to intervene to prevent student failure or drop out.
Challenges.
The multidisciplinary nature of learning engineering creates challenges. The problems that learning engineering attempts to solve often require expertise in diverse fields such as software engineering, instructional design, domain knowledge, pedagogy/andragogy, psychometrics, learning sciences, data science, and systems engineering. In some cases, an individual Learning Engineer with expertise in multiple disciplines might be sufficient. However, learning engineering problems often exceed any one person’s ability to solve. 
Each discipline brings its own metaphors and use of figurative language. Often a term or metaphor carries a different meaning for professionals or academics from different domains. At times a term that is used positively in one domain carries a strong negative perception in another domain.
