I believe that [this book] will help to serve as a pathfinder for students and educators alike, providing some of the basics of robotic theory and ways to capture the interest of and generate excitement for those in the learning environment through the use of formal, informal (outside of the classroom), and competitive robotic educational genres. Further, it provides information and discussions for determining methods of measurement regarding our ability to change the way we learn, and the associated attitudes amidst a developing workforce.
– Clayton C. Anderson, United States Astronaut
Organized into four sections, the work begins with theoretical and instructional perspectives on the use of robots in K-12 education, including how robotics works and how to measure the impact, as well as STEM (science, technology, engineering, and mathematics) career skills that can be developed through effective use. [...] This is valuable to any academic collection, from kindergarten through college, where robotics might be considered for use in the curriculum or as an extracurricular activity.

“The robotics revolution is in its nascent stage, set to burst over in the early part of the twenty-first century. Mankind’s centuries-long quest to build artificial creatures is bearing fruit.” (Brooks, 2002)
This book of chapters representing a variety of researchers’ perceptions examines the topic of educational robotic platforms that are specifically designed for learning. Moreover, the editors approached the subject with an eye towards research and evaluation asking the poignant question – what is the impact, in terms of learning, attitudes, and workforce development, of educational robot platforms in three diverse learning environments: formal classroom learning, out-of-school time, and robot competitions.
Because the field of educational robotics is relatively new, existing literature in this area frequently deals with self-reported learning and enthusiasm towards science, technology, engineering, and mathematics (STEM) subject matters as a direct result of using the educational robot as a tool for learning. This book provides additional evidence for the impact of educational robotics on learning and attitudes and provides evaluation models and examples intended to move the field forward. The editors purposely requested that chapter authors provide detailed research and evaluation designs and measurements, often asking for implementation strategies, protocol, and to report statistical tests when appropriate.
The editors come from diverse backgrounds including engineering, research and evaluation, STEM education, and youth development, and have implemented several large-scale educational robotics programs funded by the National Science Foundation (NSF), National Aeronautics and Space Administration (NASA), and other private and public partners. As both practitioners and researchers, the editors felt that there was a significant deficiency in the literature linking robotics education with STEM learning and its general impact. Thus, the impetus of this book was to identify leaders in the field of educational robotics and share their findings and best practices in one volume. The compilation provides many exciting examples and variations of using robotics as a tool for STEM education and offers evidence of its effectiveness in a number of different learning environments reaching a diverse audience of learners.
The current interest and popularity of robotics, specifically the educational robotics platforms, arises from a number of different explanations. There is, of course, the power of robotics to excite children and youth. Anyone who has observed youth working with educational robots knows their excitement in building their own robot creation and having it respond to their programming commands. Robots also have tremendous potential to support learning by actively involving students in experiences that tap science, technology, engineering, and mathematical concepts and skills. Another reason for the popularity of robotics is the relative affordability and decrease in size of the technology. Of course, there are claims that the price is still a barrier for many youth to participate in educational robotics, which in part, is true when looking at affordability to individual families. However, and this brings up the second reason for the perceived popularity of education robotics, the amount of funding available for youth programs centered on robotics is quite substantial and growing. In the United States, for instance, NSF has invested millions of dollars to bring educational robotics to formal and in-formal learning environments through the Innovative Technology Experiences for Students and Teachers (ITEST) and the Discovery Research (K-12) programs. NASA also has developed on-line robotics activities and funded educational projects through the Summer of Innovation (SOI) grants. In addition, many businesses and private foundations have provided generous support to bring robotics to children. For example, Time Warner Cable Inc., one of the largest U.S. video and high-speed data and phone service providers, has distributed significant resources through their Connect a Million Minds campaign to promote STEM education through robotics competitions. The widespread availability of educational robotics competitions and the number of volunteers associated with these competitions is another reason for the increase in popularity of robotics in education. Finally, many organizations are producing resources for students and adult facilitators that are built around educational robotics. For example, in 2010 the Boys Scouts of America released the robotics merit badge and curriculum book, and the National 4-H Council released a 4-H robotics curriculum. Combined, these two programs reach more than 8 million children across the nation.
Robotics in K-12 Education: A New Technology for Learning is a book about the effectiveness of educational robotics platforms when used as a tool for learning. The modern field of robots has been around for over 30 years. Attempts to develop autonomous mechanisms occurred centuries earlier. However, most recently we have seen an influx of new robotic systems in a variety of areas from space explorations to agriculture, from households to manufacturing production and medical institutions, and certainly through education.
For example, when the second Iraq war started in 2003, there were no ground-based robotic systems in the US inventory. By 2006 there were 5,000 units in the war, and by the end of 2008, there were an estimated 12,000 mobile robotics systems on the ground. According to the International Federation of Robotics, in 2009, the market for service robots worldwide was about 13.2 billion dollars (US). In 2009, 6.7 million domestic robots like vacuum cleaners and lawnmowers were sold and it is projected that an additional 11.4 million will be sold by 2013. In addition, leisure robotics, including educational robotics kits accounted for 3.7 million units sold, and it is projected that another 4.7 million more will be sold by the end of 2013 (http://www.ifr.org/service-robots/statistics/).
Robots are the combination of many different technologies and components acting as one system. In his book “Wired for War: The Robotics Revolution and Conflict in the 21st Century” P.W. Singer (2009) defines them as:
Robots are machines that are built upon what research call the “sense-think-act” paradigm. That is they are man-made devices with three key components: “sensors” that monitor the environment and detect changes in it, “processors” or artificial intelligence” that decides how to respond, and “effectors” that act upon the environment in a manner that reflects decisions, creating some sort of change in the world around a robot. When these three parts act together, a robot gains the functionality of an artificial organism.Using the working definition of robots from Singer (2009), many electronic toys with the “robot” moniker are missing one or more key components of a robot, according to the above definition. While these technology-based toys may also be learning artifacts, we as editors, are mainly concerned with robotic kits that can sense, plan, and act. From a learning or educational point of view, a robot brings together many different technologies to fit the “sense-think-act” paradigm. Electronics, engineering, and computer science are large components of robotics and must be explored in order for the robot to work as a system. Of course, other skills like teamwork, critical thinking, problem solving, and engineering design are also needed when creating such a robot.
A Brief History
Looking at the recent past, the word robot probably originated from the Slavic word robota and was first used in the 1921 play R.U.R (Rossum’s Universal Robots) written by Karl Capek. The precursors to the robot, which are self-operating machines or automata, date back 3,500 years to ancient water clocks (Brooks, 2002). The origin of modern self-operating machines can be attributed to Jacques de Vaucanson, the French inventor that created the “canard mécanique” (mechanical duck) also known as “the Defecating Duck” in the mid eighteenth century (Singer, 2009). Vaucanson’s duck and other mechanical humanoid inventions sparked the development a generation of similar automata.
While these early mechanical inventions obviously lacked the key ingredients of the sense-think-act paradigm, they represent the desire and development of machine-based artificial organisms. According to Brooks (2002), William Gray Walter probably developed the first robot capable of the sense-think-act paradigm in 1948. Walter developed small robots he called tortoises that had the ability to react to light. The components of the tortoises contain electric motors, a bump sensor, and most importantly two vacuum tubes used as switching elements that gave the robot the ability to respond to the light sensor data.
In the 1960’s, industrial robots arms like the UNIMATE developed by George Devol, Jr. began to appear in factories like the General Motors plant in New Jersey (Nocks, 2007. The UNIMATE was one of the first industrial robots that could be taught or programmed using metal cylinders and made use of transistors instead of vacuum tubes. The industrial robots of the 1960s were stationary but were revolutionary in the way they combined sensors and stored memory to make such products faster and more reliable.
Through the mid 1960’s and on into the 70’s and 80’s, researchers in the field were moving robots out of factories and making them mobile. In conjunction with this, a lot of work was focused on artificial intelligence (AI). Robots like Shakey, out of Stanford Research Institute Artificial Intelligence Lab (SAIL), and the Stanford CART relied heavily on computer programming to compare sensor data with the robots internal world model in order to achieve mobility. In the mid 1980’s, researchers, including Rodney Brooks, the founder of iRobot, began investigating behavior-based robotics (BBR) that relied less on a preprogrammed computational computer model and more directly on sensors that could directly relay information to the motors or actuators. The BBR model provides us with the modern definition of a robot using the sense-think-act paradigm introduced by Signer.
In the late 1960’s, Seymour Papert, at the MIT Artificial Intelligence Laboratory, began investigating the possibility of using a robot turtle tethered to a computer to teach children programming. The work at MIT lead to the development of small programmable “bricks” that contained a processor and inputs for sensors and outputs to run motors. Moreover, Papert and the MIT lab created the Logo programming language and worked with the LEGO Company to integrate the programmable brick into the LEGO building blocks. In 1998, LEGO released their RCX Mindstorm robotic kit and RCX programming code for use in education. While the LEGO kit has been commercially successful, it was not the first educational robot.
According Miller, Nourbakhsh, and Siegwart (2008), the Hero-1 robot developed by Heathkit Educational Systems was the first educational robot and was sold as a kit in the early 1980s. Today there are many other robotic kits available, and the types and variety of such kits are expanding rapidly (Miller, Nourbakhsh, & Siegwart, 2008).
In conjunction with the educational robotics, new ideas for instruction emerged with the idea of constructionism. Kafai (2006) succinctly defines constructionism as the idea of building one’s own knowledge, “in interactions with others, while creating artifacts of social relevance” (p.35). Furthermore, robots used in education utilize a problem-centered approach to learning that places a real-word or quasi-real world problem at the center of the learning experience. Placing the problem at the center of the learning experience emphasizes the student constructing deeper knowledge rather than mastery of discrete pieces of information (Druin, 2000).
“The future of robots depends on continual innovation, and that is why the initiatives to attract grammar and high-school students to the computing and engineering science through funded robot competitions are vital. We need not all be engineer, however, to understand that as with any technology, robots will have the most value where people can grasp their advantages as tools and not as toys.”Another important development in the evolution of educational robotics was the establishment and implementation of education robotic competitions. Autonomous robot competitions began around the late 1980s in the Electrical Engineering and Computer Science Department at MIT (Miller, Nourbakhsh, & Siegwart (2008). In 1992, the non-profit organization FIRST (For Inspiration and Recognition of Science and Technology) held their inaugural robotics competition for high-school students and in 1998 hosted the inaugural FIRST LEGO League (FLL) tournament (FIRST, 2008). Other competitions like BEST (Boosting Engineering, Science, and Technology), Botball, Robocup, and many others provide competitive and entertaining environments around robots. The number of participants for most of these educational robotics competitions has experienced exceptional growth. For example, more than 294,000 students are projected to participate in the 2011 FIRST series of robot competitions (FIRST, 2008).

Currently, education robotics has propagated through many educational institutions and informal learning programs providing an effective integration of science, technology, engineering, and mathematics concepts and an entertaining and challenging leisure experience. Education robots also have the ability to reach an expanding diversity of learners through their engagement with robotics-based educational experiences during their K-12 school years. Such experiences also may impact youth career planning and other important life decisions. The relationship between robotics education and learners’ experience can be found in this book, from the perspective of a variety of authors, representing many different educational backgrounds and contexts. Enjoy the reading, and share their insights into the power and potential of educational robotics in today’s formal and informal learning environments.
The Scope and Limitation of this Book
As this book examines the use of educational robotics in three distinct learning environments including formal classroom learning, informal and non-formal environments, and through educational robotics competitions, several different robotics platforms are discussed and presented with diverse education goals and learning objectives. Some chapters discuss specific programs implemented to satisfy unique needs or challenges in a certain geographic area. Other chapters discuss broad regional and national programs and competitions with large numbers of youth participants. While the objective of the book was to provide specific evidence of the effectiveness of educational robotics in the learning of STEM content and general impact to increase human potential, it is important to realize that the results may not be transferable to all robotics programs. More research is needed to identify what aspects of educational robotics work with what types of audiences and under what conditions. There is also the need for additional types of measurements and research protocols to answer the basic question of effectiveness.
How to use this Book
Seventeen chapters (across four sections) are arranged in logical order from theoretical and instructional perspectives, educational robotics in formal learning environments, programs conducted in in-formal learning environments, and robotics competitions. In the chapters discussing particular educational robotics programs, research-based measurements of the project’s impact are reported. In addition, detailed program implementation information from a variety of learning contexts is shared. A recommended strategy for reading this book is to start with the first section on theory and then move into the specific learning environment (formal, informal, or competitions) that may well capture the reader’s interest.
