Education

edit

McLaren received a B.S. in Computer Science (cum laude) from Millersville University of Pennsylvania in 1981. He later attended the University of Pittsburgh, where he received an M.S. in Computer Science in 1984 and an M.S. in Intelligent Systems in 1994. In 1999, McLaren received a Ph.D. in Intelligent Systems from the University of Pittsburgh.[8] His Ph.D. thesis was entitled "Assessing the Relevance of Cases and Principles Using Operationalization Techniques".[9] His doctoral advisor was Kevin Ashley. McLaren published a paper based on his Ph.D. in the Artificial Intelligence Journal.[10]

Career

edit

McLaren began his career as a software engineer, working for General Electric. After completing his M.Sc. McLaren joined the Robotics Institute at Carnegie Mellon University as a Research Programmer and then Project Supervisor in the Intelligent Systems Laboratory. In 1986 he joined Carnegie Group, an AI and expert systems company, as a Senior Consultant, where he was responsible for the company's expert systems projects in Europe. He later worked as a Senior Engineer and a Project Manager at the Carnegie Group in the United States until 1998. After completing his Ph.D. in 1999, McLaren joined OpenWebs Corporation where he first worked as the Director of Research and Development and then as the Director of eCommerce Technologies. In 2002, McLaren left OpenWebs to join Carnegie Mellon University (CMU) as a Systems Scientist. In 2015, he became an Associate Research Professor at CMU.[11]

From 2006 to 2010, he worked as a visiting senior researcher at the German Research Center for Artificial Intelligence in Saarbrücken, Germany, where he did research on collaborative learning, argumentation and technology for analyzing collaborative argumentation. On both the ARGUNAUT and LASAD projects, his research was focused on developing educational technology, using AI techniques, to help teachers moderate collaborative e-Discussions and arguments.[12][13]

McLaren was elected to the Executive Committee of the International Artificial Intelligence in Education Society for a six-year term in 2011. From 2017 to 2019, he served as the President of the society.[14] During his tenure as president, McLaren instituted annual (versus bi-annual) society conferences, started the bi-annual Lifetime Achievement Awards [15] and worked toward a more diverse society, regarding gender, race, and geography. As President, McLaren was quoted in a 2019 article about AI in the classroom in a PBS article[16] In 2021, McLaren was again elected to the Executive Committee of the society.

McLaren has given keynote talks at a variety of educational technology conferences, including the 11th International Conference on e-Learning and e-Teaching (ICeLeT 2024) in Isfahan, Iran,[17] the 2021 IEEE International Conference on Engineering, Technology, and Education (TALE 2021) in Wuhan, China,[18] the Australian Learning Analytics Summer Institute in 2019 (ALASI 2019),[19] e-Learning Korea 2018,[20] and the 24th International Conference on Computers in Education in 2016 in Mumbai, India.[21]

McLaren is a faculty member in Carnegie Mellon University’s METALS (Masters of Educational Technology and Applied Learning Sciences)[22] program and has taught the METALS capstone course since 2016.[23]

Research

edit

McLaren's research is focused in three areas of educational technology: learning with digital learning games; learning to argue and reason through computer-mediated collaborative learning; and learning with interactive worked and erroneous examples. McLaren has also done fundamental research in how ethical reasoning can be implemented through artificial intelligence techniques, what is sometimes referred to as “machine ethics".

Digital learning games

edit

Collaborating with Professor Jodi Forlizzi, McLaren developed a digital learning game called Decimal Point to teach decimal fractions and decimal operations to middle school students.[24] In 2017, they conducted a study, which involved 153 students from two middle schools, 70 students learned about decimals from playing Decimal Point, whereas 83 students learned the same content by a more conventional, computer-based approach. In the study, the game led to significantly better learning gains, on both an immediate and delayed posttest and was rated by the students as significantly more enjoyable.[25] They later ran several replications of the study and achieved the same results. The replication studies also revealed that the game is more effective in teaching female students than male students.[26]

More recently, McLaren and his team have explored a variety of issues related to digital learning games, including student agency,[27][28] gender effects,[29] game-based educational data mining,[30][31] and the impact of feedback and hints on student learning.[32] McLaren’s team has run studies in many middle schools in the local Pittsburgh area with these new research questions. A forthcoming book chapter describes the many studies run with the Decimal Point learning game between 2014 and 2023.[33]

In 2023 McLaren, along with his PhD student Huy Nguyen, authored a book chapter for the Handbook on AI in Education on how Artificial Intelligence has been used in digital learning games.[34] McLaren's lab has also explored the use of a large language model (LLM - ChatGPT) as a means of responding to prompted self-explanation in the context of Decimal Point.[35]

Learning to argue through computer-mediated collaborative learning

edit

Since 2005, McLaren has done research on computer-supported collaborative learning (CSCL) and how technology can be leveraged to support constructivist learning. His initial work in collaborative learning involved the semi-automated development of intelligent tutors to support collaborative learning,[36] learning of algebra through scripted dyad collaboration with Cognitive Tutors,[37] and the learning of chemistry through scripted dyad collaboration with a virtual laboratory. This research supported the claim that collaborative learning can be improved with guidance, either explicit direction on steps to take or feedback on domain content, student actions, and/or collaboration.[38]

In collaboration with colleagues and his students, McLaren has developed software tools, using the combination of AI and language analysis techniques, to analyze collaborative argumentation or e-discussions, to help classroom teachers guide multiple discussions and, consequently, to help students learn argumentation skills. In a paper published in 2010, he and his students showed that software classifiers can be created using machine-learning techniques to identify key constructs in online collaborative arguments. A teacher can use these constructs to guide students in debating and learning with one another.[39]

McLaren and his team have focused on developing analysis and feedback techniques, which leverage the structure, order, and textual contributions of arguments, so that the teacher has information to guide and advise the collaborating groups. McLaren and colleagues used graph matching, machine learning, and language processing techniques to analyze e-discussions from high school ethics and university education classrooms. He and his team developed an algorithm called DOCE (Detection Of Clusters by Example) that, given labelled example clusters, can identify similar clusters of student contributions in new discussions.[40] Ultimately, both DOCE and the combined machine learning/text mining approach are used in the context of the ARGUNAUT system to provide "alerts" so that a teacher can, at a glance, see and react to problems in the e-discussions.[41]

McLaren's web-based argumentation workspace and variety of analysis techniques was later made widely available to a range of students and other researchers through another project, for which he, along with Niels Pinkwart,[42] was principal investigator, LASAD – Learning to Argue: Generalized Support Across Domains.[43]

Learning with interactive worked and erroneous examples

edit

McLaren's research has also explored how worked examples, both correct and incorrect, can be used to help students learn. In three separate but similar studies, he and his colleagues investigated whether examples studied in conjunction with tutored problems can lead to better learning.They found that worked examples alternating with isomorphic tutored problems did not produce greater learning gains than tutored problems alone. On the other hand, the examples group across the three studies learned more efficiently than the tutored-alone group; students spent 21% less time learning the same amount of material.[44]

McLaren is among the first educational technology researchers to extensively investigate the learning potential of interactive erroneous examples.[45] In the early 2010s, he participated in several research projects that explored the instructional benefits of erroneous examples. He conducted classroom studies with middle school math students that revealed that students who worked with erroneous examples to learn decimals performed better on a delayed posttest than those who worked with problems to solve.[46] With respect to correct worked examples, he and his colleagues later showed that worked examples can lead to as much learning but in significantly less time than erroneous examples, intelligently-tutored problems, and problems to solve in the domain of chemistry.[47]

McLaren has also collaborated with Professor Ryan Baker, an expert in educational data mining, and other colleagues on analyzing the affective states of students as they learn from erroneous examples.[48]

Machine ethics

edit

As part of his dissertation research, McLaren built a computational model of ethical reasoning, specifically a program built with AI and case-base reasoning techniques that retrieves and analyzes ethical dilemmas. Thus, McLaren is recognized as one of the first researchers to contribute to the research area of machine ethics and, according to Google Scholar, is the second most cited researcher in this field.[49] The journal paper McLaren published about his PhD work [50] is often cited within this research community. McLaren also wrote a journal article describing both his dissertation research and his earlier work on an ethical reasoning system called TRUTH-TELLER.[51][52] A 2016 CNN article, in which McLaren is quoted, discusses the issue of machine ethics and robotics.[53]

Personal life

edit

McLaren's parents are Thomas James McLaren, who died in 2012 and who was a Presbyterian minister, and Shirley Martin McLaren, a former high school English teacher. McLaren was married to Gabriele McLaren (née Huber) from 1990 until their divorce in 2013. McLaren is an avid outdoorsman and hiker; he hiked the entire Appalachian Trail in 1989.[54]
