Learning Engineering: Bridging Science and Practice for Enhanced Education
The landscape of education is constantly evolving, driven by a growing understanding of how individuals learn best and the increasing integration of technology. In this dynamic environment, a burgeoning field known as Learning Engineering has emerged, aiming to systematically apply evidence-based principles and methods to create more engaging and effective learning experiences. This discipline draws heavily from educational technology and the learning sciences, focusing on supporting learners through their challenges and deepening our collective understanding of the learning process itself.
The Core Principles of Learning Engineering
At its heart, Learning Engineering is a human-centered design discipline. It emphasizes the iterative development and refinement of learning experiences, guided by analyses of rich data sets. This approach is particularly adept at addressing specific learning needs, opportunities, and problems, often with the significant assistance of technology. The process begins with a challenge in context, and the Creation stage frequently employs iterative human-centered design-build cycles. Refinements to these initial designs are then informed by data collected as the designs are implemented in real-world learning environments.
A key tenet of Learning Engineering is its interdisciplinary nature. Working collaboratively with subject-matter experts and other professionals, a Learning Engineer skillfully integrates knowledge, tools, and techniques from a diverse array of fields. These include technical disciplines, pedagogy, empirical research, and design-based methodologies. The ultimate goal is to craft effective and engaging learning experiences and environments, and to rigorously evaluate the outcomes of these endeavors. Supporting learners as they navigate the complexities of acquiring new knowledge and skills is a multifaceted undertaking, and the design of effective learning experiences and robust learner support systems typically necessitates the collaboration of interdisciplinary teams.
The Genesis and Evolution of Learning Engineering
While the foundational ideas behind what we now recognize as learning engineering can be traced back to the influential work of Herbert A. Simon, particularly his thoughts on the job of a college president in the winter of 1967, the term itself gained traction much later. The concept continued to resonate at Carnegie Mellon University, but it wasn't until businessman Bror Saxberg began actively promoting it in 2014 that it started to capture broader attention. Saxberg's initial exposure to these ideas came during a visit to Carnegie Mellon University and the Pittsburgh Science of Learning Center, affectionately known as LearnLab.
Following this visit, Bror Saxberg brought his team from the for-profit education company, Kaplan, to CMU. The insights gained during this visit led the team back to Kaplan with a renewed focus on what is now termed learning engineering, with the objective of enhancing, optimizing, testing, and ultimately selling their educational products more effectively. Saxberg, then Vice President of Learning Science at Kaplan, co-authored a significant book in 2014 with Frederick Hess, founder of the American Enterprise Institute's Conservative Education Reform Network, which prominently featured the term "learning engineering." Later, while at the Chan Zuckerberg Initiative, Saxberg collaborated with Christopher Dede on further explorations of the field.

The formalization and growth of Learning Engineering received a significant boost in 2017 when the IEEE Standards Association established the IC Industry Consortium on Learning Engineering (ICICLE) as part of its Industry Connections program. Between 2017 and 2019, ICICLE played a crucial role in fostering the development of the field by forming eight Special Interest Groups (SIGs). These SIGs served as collaborative resources, with the Curriculum and Credentials SIG, chaired by Kenneth Koedinger, pioneering work on a formal definition of learning engineering. Subsequently, the Design SIG, led by Aaron Kessler, contributed significantly to the development of a learning engineering process model.
Addressing the Application Gap: The Driving Force Behind Learning Engineering
A primary motivation for the emergence of Learning Engineering is to address a perceived deficit in the systematic application of science and engineering methodologies to the realms of education and training. The field is fundamentally aimed at improving educational outcomes by leveraging the power of computing to dramatically increase the practical application and overall effectiveness of the learning sciences as a discipline. Learning Engineering initiatives seek to bridge the gap between theoretical understanding of learning and its practical implementation in educational settings.
Furthermore, the Learning Engineering field holds the potential to automate the communication of educational insights, making them more readily available to educators. This can lead to more proactive and data-driven interventions. For instance, learning engineering techniques have been successfully applied to address persistent issues such as high dropout rates or consistently low failure rates in educational programs. Traditionally, educators and administrators might have to wait until students have already withdrawn from school or are on the verge of failing their courses to accurately identify those at risk. However, the data analysis capabilities inherent in learning engineering can enable educators to identify struggling students weeks or even months before they reach a critical point of danger.
Tools and Methodologies in Practice
The practical application of learning engineering involves a range of sophisticated tools and methodologies. Carnegie Learning's tool, LiveLab, serves as a prime example, utilizing big data analytics to create personalized learning experiences for each student. A key aspect of this personalization involves identifying the root causes of student mistakes, allowing for targeted interventions.
A/B testing is another critical methodology employed in learning engineering. This technique involves comparing two different versions of a program or learning activity to determine which approach yields the most effective results. Neil Heffernan's work with TeacherASSIST, for example, incorporates hint messages that are designed to guide students toward correct answers, a form of iterative refinement informed by student interaction data.

The development of platforms and tools to facilitate these processes is also a significant area of focus. UpGrade is an open-source platform designed for conducting A/B testing and large-scale field experiments in education, empowering EdTech companies to run experiments directly within their own software. ETRIALS, on the other hand, leverages ASSISTments to provide scientists with the freedom to conduct experiments in authentic learning environments.
Educational Data Mining (EDM) is a cornerstone of learning engineering, involving the analysis of data generated by student interactions with educational software. The goal of EDM is to understand how software can be best utilized to improve learning for all students. The datasets generated through these interactions provide the raw material that researchers use to formulate crucial educational insights. Platforms like Kaggle, a popular hub for programmers and open-source data, regularly host machine learning competitions, often featuring educational datasets. Similarly, datasets hosted by organizations like PBS and Carnegie Learning allow researchers to gather information and derive meaningful conclusions about student outcomes.
Studies have indicated that Learning Engineering may offer significant benefits by helping students and educators to more effectively plan their studies even before courses officially commence. This proactive approach can lead to better preparation and a more successful learning journey.
Diverse Applications and Products of Learning Engineering
The tangible outputs of learning engineering teams are diverse and impactful, spanning a wide spectrum of educational contexts. These products include:
- Online Courses: This encompasses everything from individual Massive Open Online Courses (MOOCs) to comprehensive online degree programs.
- Software Platforms: These are the technological infrastructures designed for delivering and managing online courses and other digital learning experiences.
- Learning Technologies: This category is broad and includes a range of tools, from physical manipulatives used to illustrate concepts, to electronically enhanced versions of these manipulatives, to sophisticated technologies for simulation and modeling, and even immersive technologies that create virtual learning environments.

The Importance of Hands-On and Experiential Learning
The principles of learning engineering often underscore the value of hands-on and experiential learning, aligning with various pedagogical theories that acknowledge diverse learning styles. For prospective students and their families considering educational pathways, particularly in engineering, the availability of facilities that promote hands-on learning is a crucial factor. While psychologists agree that individuals have different preferences for how they absorb and retain information, commonly recognized styles include visual, auditory, and kinesthetic learning. Kinesthetic learners, in particular, often grasp information best through tactile representations and direct engagement with concepts.
