A Comparative Study of the Cost of Operating the Rural High Schools of Collin County Before and After Gilmer-Aikin Legislation

A Comparative Study of the Cost of Operating the Rural High Schools of Collin County Before and After Gilmer-Aikin Legislation

Date: August 1950
Creator: Pinkerton, Woodrow W.
Description: Inasmuch as it has been assumed by the people of the State of Texas that the cost of operating the public school systems has risen since the Gilmer-Aikin Bills have gone into effect, the purpose of this study is to determine just what cost items have increased and to what extent. There are many cost items to be considered in the operation of a public school, and they have varied from year to year since the beginning of public school operation. This study attempts to determine those increased cost items in rural high schools which can be contributed directly to the passage of the Gilmer-Aikin Bills.

Nesting Ecology of the Dickcissel (Spiza americana) on a Tallgrass Prairie Relict in North Central Texas

Nesting Ecology of the Dickcissel (Spiza americana) on a Tallgrass Prairie Relict in North Central Texas

Date: May 1993
Creator: Steigman, Kenneth Lee
Description: Eighty-three species of vascular plants were inventoried on the prairie relict during peak dickcissel nesting. Based on foliar cover and occurrence frequency, the five dominant plants were heath aster (Aster ericoides), eastern gammagrass (Tripsacum dactyloides), little bluestem (Schizachyrium scoparium), sensitive briar (Schrankia roemeriana) and meadow dropseed (Sporobolus asper). Sixty-one percent of dickcissel nests were constructed on or immediately next to three plant species: eastern gammagrass, sensitive briar and green milkweed.

Litigation Subsequent to a Mandated Psycho-Educational Seminar for Divorcing Parents

Litigation Subsequent to a Mandated Psycho-Educational Seminar for Divorcing Parents

Date: May 1997
Creator: Buckner, Brenda Sullivan
Description: This study was designed to assess the difference in litigation between two courts: one mandating For Kids' Sake, a psycho-educational seminar for divorcing parents, and the other not so mandating. The level of difficulty of children's adjustment to divorce has been positively correlated with parental hostility. More hostile parents would have more contested cases, interim motions, and relitigations. This research compared final dispositions, interim motions, and relitigation between parents in two courts in Collin County, Texas. The treatment group was from the 219th District Court which mandated all divorcing parents with minor children to attend the For Kids' Sake Seminar and the control group was from the 199th District Court which did not so mandate. Archival data was collected from a computer generated list for the Total group data to assess final dispositions and directly from District Clerk files for the In-Depth group data to assess interim motions and relitigation. The Total group was comprised of 679 research subjects with 330 cases in the treatment group and 349 cases in the control group. The In-Depth group consisted of 182 cases from both courts with 84 cases in the treatment group and 98 cases in the control group. Chi square analysis ...

Design, Development, and Implementation of a Computer-Based Graphics Presentation for the Undergraduate Teaching of Functions and Graphing

Date: December 1996
Creator: Karr, Rosemary McCroskey
Description: The problems with which this study was concerned were threefold: (a) to design a computer-based graphics presentation on the topics of functions and graphing, (b) to develop the presentation, and (c) to determine the instructional effectiveness of this computer-based graphics instruction. The computerized presentation was written in Authorware for the Macintosh computer. The population of this study consisted of three intermediate algebra classes at Collin County Community College (n = 51). A standardized examination, the Descriptive Tests of Mathematics Skills for Functions and Graphs, was used for pretest and posttest purposes. Means were calculated on these scores and compared using a t-test for correlated means. The level of significance was set at .01. The results of the data analysis indicated: 1. There was a significant difference between the pretest and posttest performance after exposure to the computer-based graphics presentation. 2. There was no significant gender difference between the pretest and posttest performance after exposure to the computer-based graphics presentation. 3. There was no significant difference between the pretest and posttest performance of the traditional and nontraditional age students after exposure to the computer-based graphics presentation. Females had a lower posttest score than the mean male posttest score, but an analysis ...
