Demos with Positive Impact

David R. Hill
Emeritus Professor, Temple University

David R. Hill is Professor of Mathematics Emeritus at Temple University in Philadelphia. He served on the faculty from 1973-2018 and directed the undergraduate mathematics program from 1982–1986.

David earned BA in Education from Indiana University of Pennsylvania and a PhD in Mathematics from the University of Pittsburgh. His mathematics fields of interest are linear algebra, numerical analysis, and instructional computing. During his long academic career, David was actively involved in the Mathematical Association of America and served as president and governor of the MAA’s Eastern Pennsylvania and Delaware section. He is regarded as an expert in using MATLAB and other technologies for teaching linear algebra and numerical analysis. Recognition for his excellence in teaching include several prestigious awards including the Eastern Pennsylvania and Delaware Section of the Mathematical Association of America Award for Distinguished College or University Teaching of Mathematics in 2002, the Temple University Great Teacher Award in 2002 and the Temple University College of Arts and Sciences Distinguished Teaching Award in 1996. In 2010, he was again the recipient of the College of Arts and Sciences Distinguished Teaching Award. He has coauthored several highly regarded texts in linear algebra and is co-developer of the project Demos with Positive Impact, partially funded by the National Science Foundation (Award #9952306), which received recognition in 2008 from the Multimedia Educational Resources for Learning and Online Teaching (MERLOT) for contributions to online learning and instruction. More recently, David was recognized as an ICTCM Fellow for his long-time valuable contributions technology-enhanced mathematics instruction by The International Conference on Technology in Collegiate Mathematics (ICTCM).

David is retired and lives with his family in the Philadelphia area and continues to be interested in ways that technology can be used to enhance teaching and learning, and developing resources for instructors who may not have expertise or time to produce innovative lessons and activities using technology.

Lila F. Roberts
Professor and Dean Emerita, Clayton State University

Lila F. Roberts is Professor of Mathematics and Dean Emerita of the College of Information and Mathematical Sciences at Clayton State University in Morrow, GA. She served in her role as Professor of Mathematics and Dean from 2008 until 2021.

Lila received a BS in Mathematics Education from North Carolina State University, and MS and PhD degrees in Computational and Applied Mathematics from Old Dominion University. She began her collegiate teaching career in 1988 at Randolph Macon Woman's College in Lynchburg, VA and moved in 1989 to Statesboro, GA as a mathematics faculty member at Georgia Southern University. During her career, she has served as Acting Department Chair at Georgia Southern (2002), Department Chair at Georgia College (2003-2008), and as Dean of the College of Information and Mathematical Sciences at Clayton State. Her mathematics fields of interest are numerical modeling of physical systems, ordinary and partial differential equations. For many years, she has been passionate about the use of technology in teaching mathematics using tools such as Mathematica, MATLAB, Mathcad, Geogebra, Desmos, and 3D printing. In 1998, Lila was awarded the Award for Excellence in Contributions to Instruction at Georgia Southern University. As a participant and facilitator in the successful ATLAST (Augmenting the Teaching of Linear Algebra using Technology) project, she met David Hill and worked with him to develop Demos with Positive Impact. In 2015, as one of the inaugural recipients, she was recognized as ICTCM Fellow by the International Conference on Technology in Collegiate Mathematics. A long time online instructor in the University System of Georgia eCore collaborative, Lila received an eHero Award in 2018 in recognition for excellence in teaching and dedication to supporting online students in mathematics. Currently she serves on the Executive Steering Committee and is a program chair for the International Conference on Technology in Collegiate Mathematics. She recognizes that technology and web-based activities for teaching and learning mathematics may be a challenge for students with low hearing and sight. In 2005 she was the recipient of an NSF grant (Award #0511426, #0838113) to explore ways to adapt materials so that they are accessible for students with visual and hearing disabilities.

Lila is retired and lives in Fort Payne, AL where she lives on Lookout Mountain with her husband and tabby cat.
