The impact of technical barriers on the effectiveness of professional development as related to a distance education system-based course: A case study in the Web World Wonders environmental science learning community.

The impact of technical barriers on the effectiveness of professional development as related to a distance education system-based course: A case study in the Web World Wonders environmental science learning community.

Date: December 2003
Creator: Dawson, John L.
Description: This study reports and discusses the impact of technical barriers on the effectiveness of professional development as related to a distance education system based course: a case study of the web world wonders environmental science learning community in Florida. The project involved 4th through 12th grade public school teachers learning how to use GPS readers, digital cameras, and Arc View software for the purpose of utilizing a Website that enabled remote Internet camera access in Florida State Parks. Under the supervision of Florida State University and the Florida Department of Education those teachers received professional development in techniques for developing lesson plans utilizing the equipment and software as stated above. Using the Concept Based Adoption Model, a description of the teacher's demographics, Levels of Use and Stages of Concern with relation to gender, age, teaching experience, and technological experience was examined. Technical barriers were identified and an explanation of how they were overcome in the process of receiving the professional development is reported.

The effect of trade books on the environmental literacy of 11th and 12th graders in aquatic science.

The effect of trade books on the environmental literacy of 11th and 12th graders in aquatic science.

Date: August 2003
Creator: Lewis, Ann S.
Description: The purpose of this study was to compare the environmental literacy of 11th and 12th graders who participated in an eighteen-week environmental education program using trade books versus 11th- and 12th-graders who participated in an eighteen-week, traditional environmental education program without the use of trade books. This study was conducted using a quasi-experimental research technique. Four high school aquatic science classes at two suburban high schools were used in the research. One teacher at each high school taught one control class and one experimental class of aquatic science. In the experimental classes, four trade books were read to the classes during the eighteen-week semester. These four books were selected by the participating teachers before the semester began. The books used were A Home by the Sea, Sea Otter Rescue, There's a Hair in My Dirt, and The Missing Gator of Gumbo Limbo. The instrument used to measure environmental literacy was the Children's Environmental Attitude and Knowledge Scale. This test was given at the beginning of the semester and at the end of the semester. The scores at the end of the semester were analyzed by 2 X 2 mixed model ANOVA with the teacher as the random effect and the ...

Pretreatment Optimization of Fiberglass Manufacturing Industrial Wastewater

Pretreatment Optimization of Fiberglass Manufacturing Industrial Wastewater

Date: December 1998
Creator: Dragoo, Ron
Description: Wastewater effluent produced in the fiberglass manufacturing industry contains a significant amount of total suspended solids. Environmental regulations require pretreatment of effluent before it is discharged to the municipal wastewater treatment plant. Chemical precipitation by coagulation and flocculation is the method of pretreatment used at the Vetrotex CertainTeed Corporation (VCT). A treatability study was conducted to determine conditions at which the VCT Wastewater Pretreatment Plant could operate to consistently achieve a total suspended solids concentration ≤ 200-mg/L. Jar tests varied pH, polymer dosage, and ferric sulfate dosage. Total suspended solids and turbidity were measured to evaluate treatment performance. The data were used to determine an optimum set of conditions under project guidelines. Of twelve polymers screened, BPL 594 was selected as the most effective polymer. For cost efficiency in the wastewater pretreatment operation, recommendations suggested that treatment chemical injection be electronically controlled according to turbidity of the treated effluent.

Evaluation of the Use of the Bivalves Ischadium recurvum Rafinesque, 1820 and Corbicula fluminea Muller, 1774 as Biological Indicators of Relative Water Quality in Terms of Growth and Upper Temperature Tolerance

Evaluation of the Use of the Bivalves Ischadium recurvum Rafinesque, 1820 and Corbicula fluminea Muller, 1774 as Biological Indicators of Relative Water Quality in Terms of Growth and Upper Temperature Tolerance

Date: December 1997
Creator: Hemming, Jon Michael
Description: Growth of mussels under laboratory conditions was examined under various food regimes in different water types and temperatures. Growth was less than would be useful as an indicator and comparisons with field exposures were of minimal value. The effects of organophosphates on bivalves were examined via toxicity tests, tissue concentration, and by controlling exposure through the use of physical constraints. Upper temperature tolerance of both bivalve species was examined with respect to different acclimation temperatures and organophosphate exposures. Deviations from control exposures occurred at some temperatures. Copper effectively lowered the mean heat coma temperatures of C. fluminea at some concentrations, however, chlorine exposures did not alter heat coma temperature.

A Behavioral Model for Detection of Acute Stress in Bivalves

A Behavioral Model for Detection of Acute Stress in Bivalves

Date: May 1998
Creator: Allen, H. Joel
Description: A behavioral model for acute responses in bivalves, was developed using time series analysis for use in a real-time biomonitoring unit. Stressed bivalves closed their shell and waited for the stressful conditions to pass. Baseline data showed that group behavior of fifteen bivalves was periodic, however, individuals behaved independently. Group behavior did not change over a period of 20 minutes more than 30 percent, however, following toxic exposures the group behavior changed by more than 30 percent within 20 minutes. Behavior was mathematically modeled using autoregression to compare current and past behavior. A logical alarm applied to the behavior model determined when organisms were stressed. The ability to disseminate data collected in real time via the Internet was demonstrated.
