The Effect Of The Elementary Science Methods Classes And Field Work On Student Attitudes Toward Science And Science Teaching, Gretchen A. Northrup

Education and Human Development Master's Theses

The attitudes of sixty-nine elementary education students toward science and science teaching were measured at three different times as they progressed through the Elementary Science Methods course at the State University of New York College at Brockport during the spring of 1991. The course was divided into two parts. During the first half of the semester, the students attended methods classes at the college. At approximately midterm, the students entered elementary schools to do field work. The instrument of measure employed was the Science Teaching Attitude Scales. The three scores for each subject were compared to determine if there was ...


A Comparison Of Science And Mathematics Achievement, Attitudes, Curricular Experiences, And Career Interest Resulting From Magnet And Traditional High School Programs, Rozana Abdul Razak Aug 1991

A Comparison Of Science And Mathematics Achievement, Attitudes, Curricular Experiences, And Career Interest Resulting From Magnet And Traditional High School Programs, Rozana Abdul Razak

Dissertations

The growth of specialized schools that emphasize science and mathematics has raised questions about their efficacy in improving performance in various parameters in mathematics and science. In this study, four different components were compared. A science and mathematics experiences questionnaire determined the type and extent of student experiences in science and mathematics during high school, and student interest in science and mathematics careers. The American College Testing Program (ACT) (ACT Registration) sub-scores assessed scholastic achievement, while the determination of student attitudes towards science used the Scientific Attitude Inventory (SAI) (Moore & Sutman, 1970).

Subjects in the study consisted of three groups ...

Black Underrepresentation In Science And Technology, Robert C. Johnson Jan 1991

Black Underrepresentation In Science And Technology, Robert C. Johnson

Trotter Review

The United States is experiencing a crisis in the training of scientific and technical personnel. A recent report from the National Science Foundation (NSF) indicates that the number of U.S. citizens earning science and engineering doctorates has decreased nearly 5% since 1980. The National Research Council's study of the adequacy of research support for the mathematical sciences in the United States reveals that not only has the production of Ph.D.s in mathematics declined since 1969-70, but the percentage of U.S. citizens receiving those degrees fell during the last decade from 78% of all mathematics Ph ...

Education Faculty Publications

O trabalho relata a historia e analisa os conteúdos dos programas de estudos do Gymnasio Nacional (antigo Colégio Pedro II), propostas nas reformas educacionais brasileiras de 1892 de Fernando Lobo e de 1894 de Cassiano do Nascimento, e as compara com a de 1890 de Benjamin Constant. Demonstra que o plano curricular de 1894 manteve o elenco de disciplinas de 1890 e a distribuição das matérias nas series segundo o plano de 1892. No entanto, reduziu a carga horaria total ao nível da proposta em 1890. Estas alterações sugerem que, neste período, o ensino secundário vivia um clima conturbado e ...

Radon In Iowa Homes: Results Of Screening Measurements, Laurent Hodges, Lynne Gillette Jan 1991

Radon In Iowa Homes: Results Of Screening Measurements, Laurent Hodges, Lynne Gillette

Journal of the Iowa Academy of Science: JIAS

Homeowner-initiated short-term radon screening measurements in Iowa homes show that only about 30% of the homes have low enough radon levels - below 148 Bq/m (4.0 pC1/L) - that no follow-up measurements are necessary. Over 6 percent of the homes have screening measurements in excess of 740 Bq/m3 (20 pCi/L), a level at which prompt follow-up measurements are recommended. In all parts of the state, the range of radon results extends from low levels (below 37 Bq/m3 = 1 pCi/L) to high levels (above 740 Bq/m3). The average radon results tend to ...

Auxin-Regulated Gene Expression, Tom J. Guilfoyle Jan 1991

Auxin-Regulated Gene Expression, Tom J. Guilfoyle

Journal of the Iowa Academy of Science: JIAS

A number of cDNA clones to independent mRNAs that increase in amount after brief exposure to auxins have been isolated. From soybean, sequenced, and characterized. Increases in mRNA abundance can be detected as early as 2.5 minutes after auxin application to excised elongating regions of soybean hypocotyls. Increased transcription rates on the genes which encode the auxin-responsive mRNAs account, at least partly, for the accumulation of mRNAs. A variety of auxins induce the accumulation of the mRNAs, but other plant hormones have no effect on the mRNA abundance. Some of the genes which encode the mRNAs are clustered in ...


In Search Of A Gibberellin Receptor, Lalit M. Srivastava, Konrad A. Sechley Jan 1991

In Search Of A Gibberellin Receptor, Lalit M. Srivastava, Konrad A. Sechley

Journal of the Iowa Academy of Science: JIAS

Use of tritiated gibberellins ([3H] GA1, [3H] GA4) of high specific activity and purity has allowed the determination of GA-specific binding sites in several plant tissues both in vivo and in vitro. In cucumber hypocotyls and pea epicotyls which have been most investigated the binding of [3H] GA; occurs to soluble proteins. This binding is saturable ('n' =about 30 pmol. Mg-1 soluble protein), of high affinity (KD= about 70 nM), and is competed for by other GA, and derivatives in proportion to their biological activity in these tissues in vivo. Size exclusion and ...

Hormonal Regulation Of Gene Expression M The Aleurone Layers Of Cereal Grains, Tuan-Hua David Ho Jan 1991

Hormonal Regulation Of Gene Expression M The Aleurone Layers Of Cereal Grains, Tuan-Hua David Ho

Journal of the Iowa Academy of Science: JIAS

The aleurone layers of cereal grains offer a convenient system for studies of the molecular action of two plant hormones, gibberellins (GA) and abscisic acid (ABA). Gibberellins induce the synthesis of ix-amylase and several other hydrolytice enzymes. The action of GA is essentially at the transcriptional level, it enhances the level of steady-state levels of ix-amylase mRNAs, the rate of transcription of ᴕ-amylase genes and the activity of a trans-acting factor which interacts with specific regions of ix-amylase genes. Abscisic acid antagonizes the effect of GA by inhibiting the induction of hydrolytic enzymes, yet the effect of ABA itself is ...

Lxodes Dammini (Acari, Ixodidae) And Borrelia Burgdorferi In Iowa, Mark G. Novak, Wayne A. Rowley, Kenneth B. Platt, David M. Bartholomew, Michelle D. Senne

Journal of the Iowa Academy of Science: JIAS

A statewide study to evaluate the presence, distribution and abundance of the deer tick, Ixodes dammini, and the spirochete, Borrelia burgdorfen, in Iowa was initiated in 1989. Six hundred and seventy-one tick collections were received from health professionals, conservation employees and concerned citizens. Additional ticks were obtained by flagging, small mammal trapping and deer checks in selected areas of Iowa. Nine I. dammini were collected in 1989 from seven counties in the eastern half of the state. Six of these were tested for B. burgdorferi and all were negative. Flagging, small mammal trapping and deer checks in eastern Iowa failed ...
