County Level Population Estimation Using Knowledge-Based Image Classification and Regression Models

Description: This paper presents methods and results of county-level population estimation using Landsat Thematic Mapper (TM) images of Denton County and Collin County in Texas. Landsat TM images acquired in March 2000 were classified into residential and non-residential classes using maximum likelihood classification and knowledge-based classification methods. Accuracy assessment results from the classified image produced using knowledge-based classification and traditional supervised classification (maximum likelihood classification) methods suggest that knowledge-based classification is more effective than traditional supervised classification methods. Furthermore, using randomly selected samples of census block groups, ordinary least squares (OLS) and geographically weighted regression (GWR) models were created for total population estimation. The overall accuracy of the models is over 96% at the county level. The results also suggest that underestimation normally occurs in block groups with high population density, whereas overestimation occurs in block groups with low population density.

An Evaluation of Practices and Procedures of Book Reporting in Secondary School English Classes

Description: The purpose of the study is to make an investigation into the practices and procedures recommended and employed in making book reports in the public schools. The aim is to determine also what methods are most recommended and what practices are followed in secondary school English classes. Special attention is given to the book reporting program in the Frisco High School. Attention is given to the needs for creating a taste for good reading, the ability to interpret what is read, and to the values accruing to the intelligent reader. The reports of reading, as given by a class of secondary pupils, are analyzed to determine the methods most advisable for creating these interests and abilities.

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

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.

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

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 of the total group revealed significantly more parents in the treatment group who non suited the divorce suit and remained married (p. < .05), a significantly lower number of cases in the treatment group with interim motions (p. < .10), and a significantly lower amount of relitigation in the treatment group (p. < .05). The results showed that the court that mandated For Kids' Sake evidenced a reduction in subsequent litigation which not only benefits the legal system but also hopefully reflects lower parental hostility and higher parental cooperation, thereby benefiting the children of divorce.

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

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 of the differences showed no significance. Traditional age students had a higher posttest performance score than the mean traditional age student posttest score, but their pretest performance scores were higher as well. An analysis of the differences showed no significance. In summary, this computer-based graphics presentation was an effective teaching technique for increasing mathematics performance.
