Promoting an Integrated Science Approach in Teacher Training Programs

The Rio Grande Valley of Texas presents a unique opportunity for teacher workshops. First of all, it is separated geographically from major Texas metropolitan areas and it is still primarily rural with relatively small cities and the population is predominantly Hispanic. Teacher workshop offerings in the valley are limited and the teachers usually travel at their own expense to larger cities such as Corpus Christi, San Antonio or Houston to enhance their science background. A few years ago we were prompted by Javier Garcia to offer a workshop at the University of Texas at Brownsville. For three consecutive summers, with NASA funding and support, we taught a one week integrated science teacher workshop at the University of Texas at Brownsville. The workshop is nontraditional, as we do not concentrate on a single scientific discipline such as geology, physics but cover the broader scientific disciplines. Each day is devoted to a separate field, i.e. physics, terrestrial geology, space geology, etc. The topics can vary from year to year. Scientists are brought to Brownsville from the greater Houston area and represent the University of Houston-Downtown, Rice University, Texas Southern University and Johnson Space Center. All sessions are inquiry based and include short introductions to subjects and interactive activities that can be adapted to a variety of age groups. For example, the relationship between Earth and Moon is a crucial state middle school education standard. We begin the Earth/Moon activities with standard inquiry activities such as using flashlights to create phases of the Moon and eclipses, and extend the activities to higher mathematical levels through calculations of the height of lunar features through measuring shadow lengths, and discussion of space weather concerns for lunar exploration. As a way to illustrate the contrast between the Earth and the Moon, we show our planetarium show "Earth's Wild Ride", which is set on a lunar colony, as a start for discussion on lunar versus earth surfaces, atmospheres, and skies. The program has been a success as teachers, which have included grades 4-12, can choose the subjects. Some elect to attend the whole week while others may attend only 1 or 2 days. The advantage to this type of program is that it is easily adaptable to the science requirements for the various grade levels and it provides flexibility as some teachers are traveling 2-3 hours by automobile to attend. Thus by bringing both scientists and a planetarium to the Valley, we provide a "field trip without the bus".
