Linda Sherrell


Linda Sherrell is an Associate Professor in the Department of Computer Science at the University of Memphis (U of M). Her Ph.D. from Louisiana State University is in computer science with a minor in mathematics. She also holds M.S. and B.S. degrees in mathematics from Auburn University . Dr. Sherrell is the Principal Investigator and Director of the NSF-funded project Tri-P-LETS, which provides an enhanced computer science curriculum to eleven Memphis area high schools. She is the Undergraduate Curriculum Coordinator for Computer Science at U of M, a member of the Memphis East Engineering and Computer Science Advisory Council, and an AP Computer Science Reader. Dr. Sherrell has over 25 years of teaching experience in mathematics and computer science. She was recently appointed as a biographical candidate to represent Memphis , TN in the Empire Who’s Who of Women in Education. She has given presentations on her research and educational activities at conferences such as the International Conference on Software Engineering,World Conference on Formal Methods, Computer Software and Applications (COMPSAC), National Educational Computing Conference (NECC), and the SIGCSE Technical Symposium on Computer Science Education. Her current research interests include agile software development, process improvement, risk assessment, and computer science education.



Serious Games to Enhance Science and Mathematics

Due to the increasing number of required topics for high school science courses, teachers may have difficulty covering all the material to their satisfaction. The situation is exacerbated because courses such as biology and chemistry require lab experiments to illustrate and clarify concepts, but activities are often too complicated to complete in one or two periods.

These concerns have come to our attention through project Tri-P-LETS (Three 'P' Learning Environment for Teachers and Students). Tri-P-LETS [1], an NSF-funded project, pairs computer science students (Fellows) from the University of Memphis with high school programming teachers in Memphis area high schools. The primary goal is for students to acquire better Problem solving skills, a firm foundation in Programming concepts, and experience using a disciplined Process for software development. A secondary goal is to provide students with realistic expectations about the computer science major. Students need experience solving problems in multiple domains; furthermore, computer science majors must complete a minimum of 30 semester hours in science and mathematics. Therefore, the principal investigator and Fellows have designed several modules for high school students where students interact or build 'serious' games (i.e. games that teach or reinforce mathematics and science concepts). The Tri-P-LETS modules consist of lesson plans, worksheets, and hands-on activities with simulation tools. Tri-P-LETS research over a period of two years has shown that this combination of teaching methods improves the effectiveness of teaching and student comprehension in the domains of discrete mathematics, (e.g., permutations and combinations [2]) and theoretical computer science (e.g., finite state and cellular automata [3]).

As a result of daily interaction with high school programming teachers and students, as well as conversations with biology, chemistry, physics, and mathematics instructors at the high school and college level, the authors believe that realistic simulations can enhance laboratory experiences in science and mathematics courses thereby resulting in deeper learning. This Chat 'n' Frag, which targets high school science, mathematics, and computer programming teachers, will begin with introductory comments about our experiences using AgentSheets [4], a game-authoring and simulation tool as a mechanism to improve problem-solving skills. The majority of the session will be an interactive tutorial on AgentSheets, where participants will learn the basic programming constructs as they implement a simulation of the hydrological water cycle. Upon completion of the implementation activity, there will be a discussion of the game's implications in high school classrooms, as well as in informal learning environments. In the remaining time, participants will have the choice of working through another worksheet (either the DNA Tetris or the Dice Probability project) or playing a selection of 8 games from our Science/Mathematics gallery.
