Shaping Pre-Service Teachers\u27 Attitudes: An Inquiry Approach to Course Reform
The purpose of the study was to investigate the development of pre-service teachers’ attitudes toward teaching science with inquiry methods as the result of their participation in the two-hour elementary science methods class. Southwestern Oklahoma State University is a partner in the Oklahoma Teacher Education Collaborative (OTEC) which is funded by the National Science Foundation’s reform effort, Collaboratives for Excellence in Teacher Preparation (CETP). The reform effort focuses on the revision of the teacher preparation courses with emphasis on a systemic change in the method in which math, science, and education methods courses are taught across Oklahoma. Nine Oklahoma universities, including the University of Tulsa, Oklahoma State University, the University of Central Oklahoma, Northeastern Oklahoma State University, Cameron University, Langston University, Tulsa Community College and Southwestern Oklahoma State University, have focused on revising the identified courses with inquiry-based instruction
The permutation action of finite symplectic groups of odd characteristic on their standard modules
Motivated by the incidence problems between points and flats of a symplectic
polar space, we study a large class of submodules of the space of functions on
the standard module of a finite symplectic group of odd characteristic. Our
structure results on this class of submodules allow us to determine the
-ranks of the incidence matrices between points and flats of the symplectic
polar space. In particular, we give an explicit formula for the -rank of the
generalized quadrangle , where is an odd prime power.
Combined with the earlier results of Sastry and Sin on the 2-rank of , it completes the determination of the -ranks of .Comment: 22 page
Phenotypic Expression in the Paper Wasp \u3ci\u3ePolistes Fuscatus\u3c/i\u3e (Hymenoptera: Vespidae)
Quantification of color/color pattern in Polistes fuscatus (Fabricius) revealed that these attributes were the interaction of two antagonistic color sequences; their expression being highly correlated with nest microclimate (relative humidity-temperature). Color/ color pattern expressions were modified under experimental conditions to produce forms having natural counterparts in the field.
Principal coordinates analyses and trend surface analyses using specimens collected throughout the United States indicated three color pattern trends, representing three distinct geographic areas, and, when objectively defined, without intergradation between and/or among areas. It was concluded that fuscatus should not be considered a widespread, polytypic species; rather, as three discrete species: an eastern, P. fuscatus (Fabricius); a western, P. aurifer Saussure; and an undescribed yellow form from the southwestern United States
The First Lunar Ranging Constraints on Gravity Sector SME Parameters
We present the first constraints on pure-gravity sector Standard-Model
Extension (SME) parameters using Lunar Laser Ranging (LLR). LLR measures the
round trip travel time of light between the Earth and the Moon. With 34+ years
of LLR data, we have constrained six independent linear combinations of SME
parameters at the level of to . There is no evidence for
Lorentz violation in the LLR dataset.Comment: 7 pages, presented at the Fourth Meeting on CPT and Lorentz Symmetry,

General note on the propagation of the Acanthaceae
The power of reproduction in a a characteristic possessed by all living organisms. It is a necessity for the continuance and multiplication of
species. By this process in the plant world, the Earth's
surface is kept covered with vegetation. New areas are
encroached upon, the old areas preserved. In the struggle for existence, those plants are most widely distributed, which have successfully solved the problem of the propagation of
their species
Government financial support for civil aircraft research, technology and development in four European countries and the United States
Data on the levels of government financial support for civil aircraft airframe and engine (CAAE) research and technology (R&T) in the United States and Europe (United Kingdom, West Germany, France and The Netherlands) and means of comparing these levels are provided. Data are presented for the years 1974-1977. European R&T expenditure data were obtained through visits to each of the four European countries, to the Washington office of the European Communities, and by a search of applicable literature. CAAE R&T expenditure data for the United States were obtained from NASA and Federal Aviation Administration (FAA)
