"SemNet® Knowledge Mapping Software

Faletti, J. (designer & implementer), Fisher, K.M., Patterson, H.A., Lipson, J.I., Allen, B.S., Logan, J.D., & Thorton, R.M. (designers). SemNet ® (Version 1.1, Macintosh computer application). San Diego: SemNet Research Group.

Applications of SemNet®

Collaborative Thinking. SemNet supports collaborative endeavors such as curriculum development by teams of professionals or building a community of learners among students. Collaboration leads to conversation which, in conjunction with the skeletal frameworks of ideas that serve as manipulable reference objects for discussion, results in clarification of understanding and consensus-building.

Diagnosing and Developing Cognitive Skills. SemNet can help individuals develop systematic thinking skills for organizing and comprehending denotative factual knowledge. Instructors can diagnose many student learning problems by examining nets they have constructed.

Learning Tool. Students use SemNet to support their own personal knowledge construction. It provides scaffolding, guides organizing and thinking strategies, and serves as an external extension of short term memory.

Personal Organizer. Individuals use SemNet to construct their family trees, keep track of their committees, and analyze topics of interest to them such as the structure of the organization in which they work.

Qualitative Research Tool. Interest in SemNet as an educational tool grows steadily (see bibliography). SemNet is also useful as a qualitative research tool. See, for example: Weitzman, Eban A. & Miles, Matthew B. (1995). Computer Programs for Qualitative Data Analysis: A Software Sourcebook. Thousand Oaks, CA: Sage Publications. ISBN 0-8039-5537-5.

Study Notes / Professional Notes. SemNet allows individuals to organize their ideas in an interconnected framework and to share them with their students or peers, at a level of specificity not attainable in linear written or spoken language. It could be marketed as a form of Study Notes.

Teaching Tool. Instructors use SemNet to prepare their lectures, as a lecturing tool, and to provide students with detailed study notes.

Text Companion. A semantic network corresponding to a textbook can serve as a useful learning aid. A masking feature makes SemNet a valuable study tool that prompts integration of ideas. Ease of searching makes SemNet a useful reference tool; you can look up an idea even when you can't remember its name, if you just know something to which it may be connected.

History of SemNet Research Group & SemNet (R) Software

The SemNet Research Group (SRG) was formed at the University of California - Davis (UCD) in 1983. The SRG consisted of two Co-Directors: Kathleen M. Fisher (then on the faculty in the Division of Biological Sciences at UCD and in the School of Education and Graduate Group in Mathematics & Science Education at UC - Berkeley, and now at SDSU); and Joseph Faletti, who had completed nine years of graduate study in computer and cognitive science at UCB and had just joined the faculty at UCD (Joe is now at SDSU and UCSD). Other members of the design team included Joe Lipson , physicist and internationally renown science educator (who was initially with WICAT or the Worldwide Institute for Computer-Aided Instruction in Utah and was subsequently with CSU-Chico); Hugh Patterson, professor of anatomy (initially with the UCD School of Medicine and now at UCSF Medical School); Robert Thornton, botanist, UCD; and Carl Spring, educational psychologist, UCD. The members of the SRG were drawn together by their common interests in using cognitive science and computer technology to improve science learning. Jack Logan (Music, SDSU) and Brockenbrough Allen (Educational Technology, SDSU) joined the SRG in 1989, strengthening the SRG in multimedia design skills. Roger Christianson (Biology, Southern Oregon State College) and James Wandersee (Biology Education, Louisiana State University) have become affiliated with SRG in recent years.

Software design began in 1983. The Group began with a study strategy favored by Thornton: putting all key ideas in a domain into a hat, pulling out any two at once, and describing the relation between them. It shifted easily from there to semantic network theory, which models the way in which the human mind stores denotative factual information in long term. The goal was to bring the power of well-established cognitive theory to the aid of students engaged in learning the semantically complex domain of biology. Since it was being designed to help students master complex content areas, the application had to be fast, intuitive, and easy to use; a significant learning curve for the software would be an intolerable added burden for the student. Each design decision was guided by two concerns: Is this the best thing for the student? Is this consistent with cognitive theory and learning theory?

Software development began in 1986 on one of the first MacPlus computers. SemNet was introduced into the classroom in 1987 and about sixty faculty located around the world were invited to beta test the software. Also in 1987, SemNet received third prize in Apple's 'Wheels of the Mind' national software contest. Many new features were added to the SemNet application on the basis of needs identified by users in classrooms ranging from elementary school to graduate school, in corporations such as Bank of America, and in governmental entities such as the European Common Market. The SRG began marketing the software in 1989. In 1995, the marketing effort was terminated.

What the Research Shows. Although initially designed to support biology learning, SemNet proved to be a general purpose application suitable for organizing knowledge about many different domains. Nets have been constructed in such languages as Japanese, Spanish, French, and German as well as English. Research has shown that: students enjoy using SemNet; SemNet helps students shift from rote to meaningful learning; after using SemNet, students become more discriminating learners in their other courses, focusing on main ideas and the links between ideas; students using SemNet often acquire deeper understanding of ideas than others; group construction of nets increases student dialog, negotiation and understanding while decreasing the instructor's grading burden; instructor-generated nets provide valuable study tools in large lecture courses; reviewing nets allows instructors to identify & easily remediate a variety of learning problems; and SemNet can be a valuable qualitative research tool."

Jack Logan joined the San Diego State University (SDSU) faculty in 1969 at age twenty-four as Lecturer in Music at a time when he was working on a Ph.D. in Theoretical Studies in Music at the University of California, San Diego (UCSD) in La Jolla. Having completed a Bachelor (1966) and Master's (1967) degrees in Music at Southern Methodist University in Dallas, Texas, Professor Logan enjoyed a brief career as a trumpet soloist in the United States and orchestral player in the San Diego Symphony Orchestra and other orchestras in Southern California.

His sound recordings from this period (Stravinsky, Fanfare for a New Theater; Partch, Ulysses Departs from the Edge of the World; Erickson, Oceans; Gaburo, Mouth-Piece, et al contained both orchestral and solo music for trumpet and focused on contemporary Avant Garde music literature for trumpet and various ensembles.

For a period of fifteen years Professor Logan taught courses in the SDSU music department related to his chief professional interest, trumpet, and various secondary interests such as music tuning and intonation systems and major composer studies such as those of Charles Edward Ives and Harry Partch.

The Ives research resulted in an SDSU graduate seminar (1975) on the music of Ives and the Partch research resulted in a 33 1/3 sound recording (Harry Partch, The Dreamer That Remains, New World Records Recorded Anthology of American Music, New World Records, Inc., [Conductor], 1978.) and film, The Dreamer That Remains [Conductor], released in 1978.

In the mid-1980s Professor Logan was asked to develop a World Music course and collateral series of concerts for the Department of Music at the University of California, San Diego.

In 1989, McGraw Hill Publishing Company approached Professor Logan to author, edit, and assist in the production of a textbook designed for the core protocol of his SDSU Music in Contemporary Life course. The book, Music in Our World, enjoyed four editions and expanded to a 400-page volume by 1994. It is now available FREE on the Internet.
Turning his attention to broader applications of learning, Professor Logan joined the SemNet Research Group in the Fall of 1992 to develop the SemNet® software beyond its 1.0 version to include additional features useful in all domains of knowledge.
Dr. Logan's recent activities includes service as co-chair of the San Diego County Board of Supervisors' Economic Advisory Committee Education Subcommittee, and service on the Mayor of San Diego's City of the Future Health Care Forum.

In 1994, Dr. Logan accepted the lead role in developed the SDSU Interactive Multimedia Laboratory for the Visual and Performing Arts for the College of Professional Studies and Fine Arts. Today, the Multimedia Laboratory is a state-of-the-art facility housing the latest Apple G5 workstations, each of which is capable of one trillion calculations-per-second.

From 1995-2000, Dr. Logan and the SemNet Research Group developed the Semnet Software to be able to have it function on the world wide web as a knowledge mapping tool and as a browsing tool for discipline-specific information. See the "Knowledge Webs" developed by Dr. Logan with the SemNet Software here.

From 1996-2002, Dr. Logan, along with Samantha Mills, Kathleen Fisher, Joe Faletti, and others, developed, a dot-gone at this writing. Into every life, some rain must fall.

The early work of serving on the development team for the SemNet software has led to an abiding interest in semantic mapping. Today, the work of the W3C community, led by Tim Berners-Lee and others at MIT, has led to what is today know as The Semantic Web or SemWeb, a set of standards written by W3C that operates on top of the World Wide
Web and allows machines to more accurately understand Web data and translate it into information capable of being understood by machines, thus relieving humans of doing the more tedious work of finding, sharing, and combining information on the web.

In the Summer of 2008, Dr. Logan began working with one of the first and most interesting applications to emerge from the nascent Semantic Web community, Twine, which is, at this writing, still in 'a perpetual beta.' July, 2008, is the expected opening of Twine to Google, and Fall, 2008, is the date of the expected public release of Twine.
