Teaching Creation And Evolution In Iowa Schools, Jack Gerlovich

Iowa Science Teachers Journal

In February, 1977 a bill (H.F. 154) was introduced in the Iowa House of Representatives that read as follows: "If a public school district offers courses which teach pupils about the origin of humankind and which include scientific theories relating to origin, instruction shall include consideration of the creation theory as supported by modern sciences."' In May 1977 the Urbandale School District made a written appeal to the Iowa Department of Public Instruction to consult with experts in the science community to determine if the evidence used to support the creationist theory was credible and should be made available to …

Geology Is: A Geosciences Program For High School Students, Rion D. Turley

Iowa Science Teachers Journal

Project "Geology Is" arose out of a desire to fill an apparent gap in science education at the secondary level. It was noted that, over the years, the traditional secondary science sequence of biology, chemistry, and physics has several very weak aspects.

Four hundred twenty-six completed replies were received for a response of 95.1 percent. Data was compiled by computer and then analyzed. The findings for the 1978-1979 school year were: 1) The average age of the public school superintendent was forty-seven years; 2) Ninety-eight point two percent were …

A Study Of Principals’ Opinions About Minimum Competency Testing In Their Schools, Thomas J. Renze

Dissertations and Theses @ UNI

Minimum competency testing (MCT) has been a controversial educational issue for the past several years. Much of the literature on this topic has been written by educators and/or members of the public who are not directly responsible for implementation, administration, or evaluation of test results. This study was designed to gather information from primary sources concerning their opinions about the use of minimum competency testing programs in their own schools. Data was gathered during the 1978-79 school year.

Professional literature indicates that the minimum competency testing movement was generally initiated by individuals and groups outside of educational circles who were …

Effects Of The Approach Path On The Displacement Of The Center Of Gravity During A Vertical Jump, Joyce Ann Davis

Dissertations and Theses @ UNI

Many sport activities require the use of the vertical jump in some manner. An approach run to a vertical jump is desirable because it enables a jumper to convert the horizontal momentum that is built up during the preliminary steps into vertical momentum for the jump. Cinematographical analysis was utilized to study what effects the approach path has on the displacement of the body's center of gravity during a vertical jump. Nine college-aged female subjects were filmed with a high speed camera while performing a vertical jump from both a curved and straight approach path. All subjects used a three …

Distributed Parameter Watershed Sedimentation Model, Patricia M. Witinok, Gene Whelan

Proceedings of the Iowa Academy of Science

The model developed herein uses a detailed geometric description of the watershed and incorporates the kinematic wave approximation of the equations of motion, superposition, and time-lag methods to analyze flood and sediment flows. The watershed is broken down along tributary divides into subcatchments, which are divided along lines of steepest slope into "streamtubes." These streamtubes are further divided according to slope into "segments," such that topographic parameters of each segment are spatially constant over the segment. The flow from the streamtube enters the channel at the mid-point of the stream tube bordering the channel. This point is called a "node." …

An Investigation Of Reversed Phase Thin-Layer Chromatography For The Separation Of Polycyclic Aromatic Hydrocarbons, Marvin V. Gibson

Dissertations and Theses @ UNI

A reversed phase thin-layer chromatographic method employing the chemically bonded octadecylsilane as the stationary phase (Whatman KC18), has been investigated for the simultaneous analysis of polycyclic aromatic hydrocarbons (PAH) and nitrogen heterocyclics (aza-arenes). Separations of mixtures of reference compounds were obtained with a number of mobile phases (developers) and the separation efficiencies depending on the individual solvent components were summarized. Double development and twodimensional thin-layer chromatography were used for identification purposes involving several environmental samples. This method, coupled with selective excitation fluorescence spectrometry, proved to be effective for the quantitative measurements of selected PAH and aza-arene compounds. The analytical procedures …

Self Concept And Its Relationship To Reading, Phyllis J. Demro

Graduate Research Papers

Self concept is a unique set of perceptions, ideas, and attitudes which mold the individual. It refers directly to the image each individual has about himself. Aspects of self concept include self, self in relation to others, self as achieving, self in school, and physical self. Self concept must be placed in its proper perspective of importance, regardless of the aspect being considered. One of the primary purposes of the teacher is to determine the nature and scope of the child's self concept and provide the necessary experiences to make that concept as useful to the student as possible. Self …

The Effects Of Anxiety On Oral Reading Miscues, Marlene Sprain

Graduate Research Papers

Anxiety is a condition which is hard to define even though everyone has experienced it to some degree and at one time or another. One problem involved in defining it is to determine whether it is a long- or short-term characteristic. This is an important point because if anxiety is a long-term personality trait we need to find out which persons are anxious, how they got that way, and how they are coping with the condition. If, on the other hand, anxiety is merely a temporary state, we need to determine during which situations the anxiety is aroused and how …

A Tip About Controversy, James Hungerford

Iowa Science Teachers Journal

Under certain circumstances, scientific theory may conflict with the existing views of the community in which you teach. Such controversy, if handled properly, may serve as a vehicle for stimulating learning and understanding. Such issues, handled improperly, often result in chaos for everyone involved. As a professional educator, the responsibility for "if' and "how" controversial issues are faced in the classroom is yours.

Istj, Religion And Politics: An Editor's View, A. C. Haman

Iowa Science Teachers Journal

During the past year, the Iowa Science Teachers Journal has been criticized (and in one instance politically threatened) for not publishing sectarian interpretations of natural phenomena which conflict with widely accepted scientific theory. It is a policy of the journal not to publish sectarian or political views concerning natural phenomena. The purpose of this editorial is to provide clarification of the journal's role in reporting advances in science and science teaching to the public and parochial schools of the state.

Moon Phases And Piaget, Carolyn Brockway

Iowa Science Teachers Journal

According to Piaget, a teacher must be aware of the mental development of children in order to present concepts to students in a meaningful way. Too often, the mental processes of children are ignored in teaching. After years of teaching the phases of the moon in the traditional manner of using diagrams in texts; drawings on the board and teacher demonstrations with models, I discovered, several months after instruction, that a majority of my students could not demonstrate the positions of the moon in relation to the sun and earth in explaining moon phases.

The Earth's Magnetic Field, Robert S. Carmichael

Iowa Science Teachers Journal

In the year 1600, the Englishman William Gilbert published "De Magnete", one of the first true scientific treatises. He had studied, with a compass needle, the dip and pattern of the magnetic field around a sphere of lodestone magnetite (the mineral Fe304). Further, he deduced that the Earth had a similar field, and was therefore like a giant magnet.

The Iowa Tests Of Basic Skills: Indicators Of Science Achievement, Darrel Hoff, Charles Hohensee

Iowa Science Teachers Journal

In most public schools in Iowa, the Iowa Tests of Basic Skills (ITBS) are administered to grades three through eight. These tests provide a wealth of information concerning achievement in basic academic skills, but they do not provide a direct assessment of achievement of scientific skills. As a result, junior high teachers often have little data for assessing the scientific abilities of their students unless they administer additional tests. Science achievement, per se, is not usually measured in Iowa's public schools until the ninth grade, when students are given the Iowa Tests of Educational Development (ITED).
