Relationships Among Ffa Membership Factors and Vo-Ag Programs in the Eastern Ffa Region by Elmer L Cooper( Book )

1 edition published in 1981 in English and held by 2 WorldCat member libraries worldwide

At the request of the Future Farmers of America (ffa), an analysis was conducted of reasons for a decline in membership in 1977-79 after a 40-year period of steady growth. Factors such as the vocational-agriculture teacher shortage, number of chartered ffa chapters, certification status of teachers, ffa membership costs, and contract length of teachers were studied to determine their relationships to ffa membership trends. Following a pilot study, questionnaires were developed and mailed to a 1 percent random sample of vocational agriculture students in the 15-state ffa Eastern Region, and to 5 percent of the teachers of vocational agriculture in the region. A total of 1,527 questionnaires were sent, with a return of 89.7 percent (1,367). Analysis of the data gathered showed that some of the factors which are generally thought to have a negative influence on ffa membership numbers did not prove to do so in this study. There did not appear to be definite relationships between ffa membership changes and the shortage of vocational agriculture teachers, the use of teachers without full certification, the level of ffa membership costs, nor changes in the length of vocational agriculture teacher contracts. However, there did appear to be a relationship between the decline in ffa membership in the Eastern Region and the numbers of chartered ffa chapters. Continuance of the study on a national level, repeated at five-year intervals, would provide the ongoing assessment which must occur if the ffa is to continue its successes and change to meet future needs.

An Exploratory Study of the Relationship of Job Satisfaction to WorkValues in the Maryland Cooperative Extension Service by Gene Child Whaples( Book )

1 edition published in 1977 in English and held by 2 WorldCat member libraries worldwide

Two hundred seventy-two faculty members of the Maryland Cooperative Extension Service were surveyed to determine their work values and explore possible relationships between work values and job satisfaction. The survey instruments used were Values for Working and County Extension Agents' Job Satisfaction Inventory. The results, based on 262 responses, are as follows: there were differences in values system orientation and level of job satisfaction among Maryland Extension faculty; there was a relationship between work values and job satisfaction; eight factors contributing to variance in job satisfaction among the faculty were identified (achievement, supervision, salary, reporting, responsibility, advancement, recognition, and working conditions); faculty work values (based on the theoretical framework of Hughes and Flowers) were found to be highest in the existential value orientation followed by sociocentric, manipulative, conformist, tribalistic, and egocentric; a significant relationship exists between the egocentric values system and job satisfaction; and, finally, research findings of Hughes and Flowers which showed that disparity in values system orientation between management and employees will lead to lower job satisfaction were supported. (This report contains thirty-three data analysis tables. The survey questionnaires are appended.) (em)
Model for evaluation of secondary school programs of vocational education in agriculture by Alfred H Krebs( Book )

1 edition published in 1969 in English and held by 2 WorldCat member libraries worldwide

This research project focused on the development of instruments and procedures which a local secondary school evaluating group may use for conducting its own evaluation of the local program of vocational education in agriculture. The report covers Phase I of a four-phase project and presents the development and trial of instruments and procedures in two Maryland public high schools. Twenty-five instruments and guides are presented with suggestions for their use as well as suggestions regarding the treatment of the data. Further testing and refinement of the instruments and procedures are scheduled for later phases of the project. A bibliography is appended. (Author/GB)
Integrating Reading Instruction into Vocational Agriculture Classes. Miscellaneous Publication 586. Contribution Number 3813 by Dorothy D Sullivan( Book )

1 edition published in 1966 in English and held by 2 WorldCat member libraries worldwide

An experiment was conducted to determine whether special reading instruction integrated with agricultural instruction would result in improved reading ability and increased achievement in subject matter. Random assignment was made of vocational agriculture classes in 12 Maryland schools to experimental and control groups. Units on soil sampling and agricultural cooperatives were prepared and supplied to teachers in all groups. In addition, the experimental group teachers followed suggestions for improving reading ability as set forth in a written guide. The "Diagnostic Reading Tests, Survey Section, ""Kuhlman-Anderson Intelligence Test, 7th Edition," and "Sequential Tests of Educational Porgress" were used in pre- and post-testing. Reading abilities of students in the study were below national norms. Statistical treatment of data showed no differences between experimental and control groups in performance on reading, social studies, and science standardized tests, when scores were adjusted for I.Q. and pre-test scores. Subjective responses to teachers suggested that the reading guide might have merit, if revised. It was concluded that the length of the experiment was inadequate and standardized tests in agricultural subject matter was a serious limitation to interpretation of results. (Jm)
Undergraduate Academic Achievement and Teaching Performance by V. R Cardozier( Book )

1 edition published in 1965 in English and held by 2 WorldCat member libraries worldwide

The objectives of this study were to determine (1) the relationship between teacher performance and undergraduate achievement in selected disciplines, (2) the relationships between undergraduate achievement, both total and in each of 12 subjects, and teaching performance, both total and in nine teaching functions, and (3) the variability of teacher performance according to undergraduate academic achievement. A 25 percent random cluster sample of 1959 and 1960 agricultural education graduates from 16 institutions in the united states produced 188 teachers who had completed between 2 1/2 and 3 1/2 years of teaching in their own states. Data were gathered on academic achievement from college transcripts and on teaching performances from ratings by principals and district supervisors. Significant positive correlation was found between teaching performance and academic achievement in biological sciences, agricultural education, and student teaching. Negative correlation was found between teaching performance and academic achievement in mathematics, general education, and agricultural economics courses. There was no significant difference in the variation of teaching performance among teachers grouped according to undergraduate achievement. A previous assumption that average students are the best teachers was not sustained. (Jm)
Teaching nutrition by teams-games-tournaments : an application of behavioral analysis by Lois Ann Wodarski( Book )

1 edition published in 1979 in English and held by 2 WorldCat member libraries worldwide

Presented in the first part of this document are results from a pilot study designed to determine the effect of the Teams-Games-Tournaments (TGT) method on students' and teachers' nutrition knowledge. (The TGT is a structured sequence of learning activities combining small groups, instructional games, and tournaments to teach nutrition concepts.) Two curricula incorporating the TGT technique were developed and tested in two self-contained sixth grade classrooms and two high school home economics classes. In general, data obtained from questionnaires developed to assess students' and teachers' reactions to the TGT nutrition units indicated that the majority of students in all classes enjoyed the method. Students enjoyed working in groups and competing in tournaments, expressing the feeling that they learned "a lot" about nutrition and, importantly, the belief that what they learned would influence their future food choices. Teachers indicated that the units were well-planned, thorough, and easy to follow, noting that the children enjoyed working in groups and that the TGT activities not only increased the students' knowledge of nutrition, but also reinforced reading, math, spelling, and measurement skills. A detailed description of the contents and activities of the two curricula comprises the second and third sections, which are the major portion of the document. (MP)
Biomonitoring and hazard assessment evaluation of contaminated groundwater at Aberdeen Proving Ground-Edgweood Area Beach Point Penincula [sic by Dennis T Burton( )

1 edition published in 1994 in English and held by 1 WorldCat member library worldwide

Contaminated groundwater, which contained multiple heavy metals and chlorinated aliphatic hydrocarbons, from the surficial aquifer (well CC-33B) at Beach Point located in the Canal Creek Area of the U.S. Army Aberdeen Proving Ground-Edgewood Area, Aberdeen, Maryland, was evaluated for toxicity and environmental hazard. Toxicity was detected at various groundwater concentrations by 7 of 9 biomonitoring systems. when estimated maximum acceptable toxicant concentrations (MATC) were established, the data for algae, invertebrates and fish suggested that the groundwater would not be harmful at a concentration of 10% groundwater by volume. Likewise, no genotoxicity (Ames and SEC assays), develop- mental toxicity (FETAX), or chronic histopathology (9-month fish test) occurred at 10% groundwater by volume. The groundwater was considered to be a potentially excessive hazardous material to the benthic biota of the Bush River when a number of conservative assumptions (contaminant distribution and discharge rate of the aquifer) were used in the hazard assessment. However, the potential water quality impacts were judged to be minimal if a mixing zone were to be granted by the State of Maryland which allows for local exceedences of water quality standards
The Maturity of Vocational Attitudes in Adolescence. Apga Inquiry Series Number 2 by John Orr Crites( Book )

1 edition published in 1971 in English and held by 1 WorldCat member library worldwide

The research in this monograph was stimulated by the need for an objective, standardized measure of vocational maturity which would provide an empirical referent for the conceptual terms of vocational development theory. The instrument constructed for this purpose is the Vocational Development Inventory, which consists of a Competence Test and the Attitude Scale. The former is designed to assess the cognitive components of vocational maturity; it has not been completed yet. The latter is intended to define operationally the cognitive elements in vocational maturity. Findings include the following: (1) the relationship of items to grade was stronger than it was to age; (2) there was a trend for item endorsements to change from True to False across grades; (3) there were two"stages" in the item curves, between the 6th and 7th grades and the 9th and 10th grades; and (4) a subset of items which were unrelated to age or grade and which elicited deviant responses might constitute an index of vocational maladjustment. The Vocational Development Project was established, also, to implement a program of different, but interrelated types of research: survey, technique, theoretical, and applied. (Author/TA)
Evaluation of Biomonitoring Systems for Assessment of Contaminated Waters and Sediments at U.S. Army Installations( )

1 edition published in 1994 in English and held by 1 WorldCat member library worldwide

The primary objective of the study was to evaluate the use of several biomonitoring systems for hazard/risk assessment of potentially contaminated waters and sediment-associated contaminants at U.S. Army Installations. An array of toxicity tests structured in a tiered framework, which ranged from a rapid acute test of 5 minutes in duration to a 9-month chronic carcinogencity assays was evaluated. Both aqueous and sediment phase tests were evaluated. The studies were structured, where possible, to provide toxicity system evaluation data as well as data for various Superfund sites at the Aberdeen Proving Ground, Aberdeen, Maryland. Most screening-level Superfund ecological risk assessments require the use of ecotoxicity values which provide chronic no-observed-adverse-effect-level (NOAEL) data for exposures to contaminants. Several of the biomonitoring systems evaluated in the current study provided appropriate NOAEL data. Other assays such as, the Ames mutagenicity assay, frog teratogenesis assay-Xenopus (FETAX); and Japanese medaka (Oryzias latipes) carcinogenicity assay are not normally structured to provide NOAEL endpoints. The use of the systems, however, as weight-of-evidence for ecological hazard/risk assessment is presented for various Superfund sites. Likewise, the results of the studies used for regulatory and compliance activities by the Army, EPA, and State of Maryland regulators are presented in the report
Toxicity of nitroguanidine, nitroglycerin, hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) and 2,4,6-trinitrotoluene (TNT) to selected freshwater aquatic organisms : final report by Dennis T Burton( )

1 edition published in 1993 in English and held by 1 WorldCat member library worldwide

The primary objective of the study was to conduct the necessary toxicity tests to complete the existing data base for deriving U.S. EPA numerical water quality criteria for freshwater organisms exposed to nitroguanidine (NQ), nitroglycerin (NG), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), and 2,4,6-trinitrotoluene (TNT). A secondary objective of the study was to determine what effect photolysis may have on the toxicity of NQ and RDX. The acute toxicity of NQ was established for the hydra (Hydra littoralis), cladoceran (Ceriodaphnia dubia), rainbow trout (Oncorhynchus mykiss), and fathead minnow (Pimephales promelas). The following NQ chronic tests were performed: 7-d cladoceran, 28-d ELS rainbow trout, and 28-d ELS fathead minnow. Photolyzed NQ was 100-fold more toxic to the cladoceran than the parent compound. NG acute toxicity was determined for the green alga (Selenastrum capriocornutum), hydra, cladoceran, midge (Paratanytarsus parthenogenticus), and fathead minnow. The following chronic tests were conducted with NG: 7-d cladoceran, 60-d ELS rainbow trout, and 28-d ELS fathead minnow. RDX acute toxicity was established for green alga, hydra, midge, cladoceran, and fathead minnow. The following chronic tests were conducted with RDX: 7-d cladoceran, Nitroguanidine, Nitroglycerin, Hexahydro-1,3,5-trinitro-1,3,5-triazine(RDX), 2, 4,6-Trinitrotoluene(TNT), Acute toxicity, chronic toxicity, Photolysis, Selenastrum capricornutum, Lemna minor, Hydra littoralis, Paratanarsus partheno life cycle, and 28-d ELS fathead minnow. genticus, Ceriodaphnia dubia, Pimephales promelas, Oncorhynchus mykiss
