REPORT ON THE 1994 SPRING MEETING OF THE TEXAS SECTION OF
THE AMERICAN PHYSICAL SOCIETY
11-12 March 1994; Richardson, TX

The annual Spring Meeting of the Texas Section of The American Physical Society was held on the campus of the University of Texas at Dallas in Richardson, Texas, on 11-12 March 1994.

About 500 persons registered for the meeting, which was held jointly with the Texas Section of the American Association of Physics Teachers and Zone 13 of the Society of Physics Students.

A plenary session on "Frontiers of Physics" featured invited talks on the latest results from the Hubble Space Telescope: "Imaging with the Repaired Hubble Space Telescope," by Dr. Jon Holtzman, Lowell Observatory; and "Spectroscopy with the Hubble Space Telescope, " by Dr. Reginald J. Dufour, Rice University.

There were 89 APS contributed papers arranged into 8 sessions covering most areas of physics, 49 AATP contributed papers in 4 sessions, and 10 SPS papers. The AAPT Section arranged a plenary session on "Naive Beliefs about Physics and Education " by Dr. David Hestenes, Arizona State University, two panel discussions, two invited paper sessions, a poster session, and 25 workshops on physics education topics for area teachers.

The Chairs' Breakfast on Friday morning was attended by 21 persons. The luncheon, attended by 187, was followed by a brief business meeting. The Banquet was attended by 215 persons. It was preceeded by a reception honoring past recipients of the TSAAPT outstanding pre-college teacher award, and was followed by an entertaining, illustrated lecture on "Physics in the Forensic Laboratory" by Dr. Alan Weckerling.

The committee to select the outstanding student presentations, chaired by Chair-Elect Ed Fry, reviewed the presentations of the 35 graduate and undergraduate students competing and selected four students to receive awards. Receiving awards of $150 were: A. Aranda, UT El Paso; A. Aviles, University of North Texas; James A. Redmon, Abilene Christian University, and R. Wimp, Southwest Texas State University. The awards were supported by the Section's general operating fund.
