Survey Of In-Service Needs Of Iowa Science Teachers, Timothy Cooney, Darrel Hoff
Survey Of In-Service Needs Of Iowa Science Teachers, Timothy Cooney, Darrel Hoff
Iowa Science Teachers Journal
National concerns about science education have suggested a number of factors which are contributing to what is now being called a crisis. One such factor is that colleges and universities are producing fewer certified science teachers, even as many science teachers are leaving the classroom to pursue other employment. A second factor is that the average age of the science teacher is increasing and many teachers have not continued to update their training. A third factor; which may be a result of the first two, is that the number of secondary students taking science and the number of courses they …
Perceptions Of Science Of Third, Seventh, And Eleventh Grade Students Enrolled In Cedar Rapids (Iowa) Schools, Stuart O. Yager, Robert E. Yager
Perceptions Of Science Of Third, Seventh, And Eleventh Grade Students Enrolled In Cedar Rapids (Iowa) Schools, Stuart O. Yager, Robert E. Yager
Iowa Science Teachers Journal
As a part of the Third Assessment of Science for the National Assessment of Educational Progress (National Assessment, Note 1.), an extensive battery of items dealing with the affective domain were included for the first time. Information for the National Assessment of Educational Progress is gathered from a stratified sample drawn from the entire United States. All questions are reviewed by education specialists (including science educators, measurement experts, and lay persons). The questions are administered to 2,500 persons selected to represent varying age levels. For NAEP studies, four samples are used, namely 9, 13 and 17-year-olds and a young-adult sample.
The Identification Of Unknown Bacteria, Steve Ziser
The Identification Of Unknown Bacteria, Steve Ziser
Iowa Science Teachers Journal
A major activity of most college level introductory microbiology courses is the identification of one or more unknown bacterial species. The ways suggested in many lab manuals for identifying bacteria are often unorganized and difficult to follow. In addition, the huge volume of information often required to make a diagnosis may overwhelm beginning microbiology students who are largely incapable of weighing the importance of many of the tests in trying to decide how to best proceed with the identification. Microbiology manuals too often overlook the fact that identification is an orderly process of moving from general characteristics to more specific …
Reading Rocks: Early History Of Paleontology, Mary Simonis-Parish, Doris A. Simonis
Reading Rocks: Early History Of Paleontology, Mary Simonis-Parish, Doris A. Simonis
Iowa Science Teachers Journal
The word paleontology is taken from the Greek words 'palaios' meaning old, 'ontos' a being, and 'logos' to study (Hamlyn, 1968). It is usually loosely translated to mean 'the study of past life', or 'the study of fossils'. Though the word itself has been used only in recent times, an interest in fossils (as interesting objects literally "dug out of the earth") is probably as old as humankind. The subject of this paper is the development of ideas that deal with the significance and origin of fossils. The explanations range from ancient times up to the nineteenth century when fossils …
Collecting Reptiles And Amphibians For Classroom Use, Donald J. Perschau
Collecting Reptiles And Amphibians For Classroom Use, Donald J. Perschau
Iowa Science Teachers Journal
The advantages of living organisms in the classroom are well known to biology and elementary teachers. Live animals and plants spark interest, provide color and movement, can be used as teaching materials, and can generally improve the classroom environment. Organisms commonly found in classrooms include plants from the genera Coleus, Dracena, Philodendron, and many others, and animals which are often small mammals or perhaps tropical fish. Seldom does one find more primitive vascular or non-vascular plants, invertebrate animals, reptiles or amphibians. It has been my experience that these organisms have much to add to the classroom and …

Science And Math Teachers: A National Survey Of Supply And Demand, Trevor Howe
Science And Math Teachers: A National Survey Of Supply And Demand, Trevor Howe
Iowa Science Teachers Journal
Total enrollments in Iowa public schools, K-12, have declined. Total enrollments have declined by 130,116 students in ten years. The projected enrollments are expected to drop 31,444 students in the next five years. Obviously the implication is a reduction in the number of teaching positions at both the elementary and secondary levels over the next several years. However, current data indicate that the science and math teacher supply is decreasing more rapidly than student enrollment.

The Search For Excellence In Science Education, John E. Penick
Iowa Science Teachers Journal
In 1976 several NSF funded studies revealed the current state of science education in the United States. In 1978, a synthesis of the more than 2,000 pages of information from those three NSF reports and the NAEP data was begun by twenty-three science educators throughout the U.S. The synthesis researchers worked independently in small teams, each focusing on one aspect of science education: elementary science, biology, physical science, science/technology/society, or inquiry. A critical part of the synthesis analysis was developing a description of an ideal or desired state for a focus area and then comparing the actual to the desired …

Governor's Task Force Report On High Technology In Iowa: Results And Applications To The Crisis In Science Education, David H. Swanson
Iowa Science Teachers Journal
Governor Robert Ray, on May 18, 1982, directed a High Technology Task Force to examine the feasibility of the development of high technology industries in Iowa. This task force after 5½ months of study, made its report to the governor. The report found that 75 percent of the new U.S. manufacturing jobs created during the past 25 years were in seven basic industry groups. These industries were generally described as high technology. The report also concluded that in the future manufacturing employment increases were most likely to occur in high technology industries. Considered major among the locational factors of high …

Students' Views Of Science Teachers, Classes, And Course Content, Robert E. Yager, Ronald J. Bonnstetter
Students' Views Of Science Teachers, Classes, And Course Content, Robert E. Yager, Ronald J. Bonnstetter
Iowa Science Teachers Journal
The Third Assessment of Science, part of the National Assessment of Educational Progress (NAEP), provided needed views concerning successes and failures of school programs (Holmes & Wright, 1980; National Assessment, Note 1). For the first time, the 1977 assessment of science included an extensive battery of items dealing with the affective domain. Present plans include abandoning future assessments in science that would permit a longitudinal study of such outcomes of science instruction. This unfortunate situation prompted the authors to replicate the study with Iowa samples five years later.

Science and technology influence every aspect of our lives. They are central to our welfare as individuals and to the welfare of our society. All around us are examples of the importance of science and technology for production of food, shelter, clothing, medicines, transportation, and various sources of energy. There are an increasing number of science- and technology-related societal problems as well as increasing societal benefits. Science and technology are central to our personal and cultural welfare and to many societal problems. We must insure appropriate science education for all citizens.
