Using Technology Within The Teacher Preparation Program As A Model For Effective Instruction, J. P. Johnson, L. E. Wilkowski

Journal of Mathematics and Science: Collaborative Explorations

This article describes a methods course for teachers of elementary science and how it was enhanced to increase students’ abilities and attitudes toward using technology as a tool in teaching science. The course was enhanced as a result of the Virginia Collaborative for Excellence in the Preparation of Teachers (VCEPT) project. Prior to this project, the course was known for its constructivist approach, cooperative group activities, and experiential base that allowed students to actually do and teach elementary science. As a result of VCEPT, the class now also features an elaborate technology component. Technology of many types are regularly modeled …

Culturally Important Issues And Science: A Gender And Science-Interest Investigation, William W. Cobern, Cathleen C. Loving

Scientific Literacy and Cultural Studies Project

Elementary science methods students nearing completion of their preservice teacher preparation are an important source for gauging views about science and its relation to culture. This research investigates gender and science interest as correlates of the valuation of science vis-à-vis nine culturally important categories as measured by the Thinking About Science Survey. Over one thousand male and female students at a large midwestern university took part in this study.

Storm Deposition Of Pisoids In The Humboldt Oolite Member Of The Gilmore City Formation (Mississippian), North-Central Iowa, Shawn C. Thomas, John R. Groves

Journal of the Iowa Academy of Science: JIAS

Pisoids (concentrically laminated carbonate grains, > 2 mm in diameter) are abundant in the upper Humboldt Oolite Member of the Gilmore City Formation (Mississippian). Their cortices are isopachous and nuclei include both intraclasts and fragments of preexisting

pisoids. They occur both as floating grams m a fine grainstone matrix and concentrated at the bases of distinct layers that may be crudely graded beds. Sorting characteristics and the presence of broken and abraded pisoids suggest not only their origin as primary free grams, but also storm influence in the deposition of local pisolite layers. Regionally, the upper Humboldt Oolite is characterized by …

A Comparative Analysis Of Student Performance Utilizing Computer Based Instruction And Teacher Based Instruction Within A Secondary Mathematics Setting, John Douglas Sawtelle

The overall purpose of this project was an assessment of student performance before and after using computer based instruction versus a before and after assessment using traditional teacher based instruction.

Science, Technology And Society In Science Education, Debra Tedman

Shannon Research Press

This study had four major purposes. First, the study developed and used scales to measure the strength and coherence of students', teachers', and scientists' views, beliefs and attitudes in relation to science, technology and society (STS). Second, the factors which influenced the development of strong and coherent views on STS by students, were examined. Third, the study investigated whether male and female students differed in the strength and coherence of their views on STS. Fourth, structured group interviews with teachers provided information for the consideration of the problems encountered by teachers and students in the introduction of STS courses.

Effects Of Field Size And Landscape Composition On Grassland Birds In South-Central Iowa, David Joseph Horn, Rolf R. Koford, Malinda L. Braland

Journal of the Iowa Academy of Science: JIAS

Many species of grassland birds have been shown to avoid smaller fields. The avoidance of smaller fields, however, has not been consistently reported; avoidance may occur in one study, but not in another. To examine one possible reason for these inconsistencies, we examined how landscape composition influenced the relations between occurrence or abundance and field size. The study took place during the 1998 breeding season on 44 Conservation Reserve Program (CRP) fields located in Adair, Ringgold, and Union counties. The relations between occurrence, abundance, and field size were not influenced by landscape composition for any species.

Factors Influencing The Occurrence Of Birds That Use Feeders In Iowa, David Joseph Horn, Steve E. Fairbairn, Richard J. Hollis

Journal of the Iowa Academy of Science: JIAS

Since its inception in 1984, data from the annual Iowa "Winter Bird Feeder Survey" have provided valuable information about birds that use feeders in Iowa such as spatial and temporal population trends. Using data from the 1988 and 1994 Surveys, we examined how the occurrence of bird species that use feeders was influenced by geographic location, the habitat surrounding a house, and the types of seeds offered at a house. Of the 23 species examined, the occurrence of 8 species was influenced by latitude, 22 species were influenced by the habitat surrounding the house, and 22 species were influenced by …

Inheritance Of Gray Leaf Spot Resistance In Corn, J. M. D. Crowley, A. R. Hallauer, C. A. Martinson

Journal of the Iowa Academy of Science: JIAS

Gray leaf spot disease, caused by Cercospora zeae-maydis Tehon and Daniels, has become a significant disease in Iowa corn (Zea mays L.) production. Incidence of gray leaf spot has increased with the increased use of conservation tillage practices. The inheritance of resistance to gray leaf spot was studied via use of generation mean analyses for five crosses and via use of 100 S₁ progenies developed from an F₂ population. Experiments were conducted at two locations that included either natural or artificial inoculation with C. zeae-maydis spores. Additive and dominance effects were significant in nearly all instances. Heritability for …

Fungi And Diseases Associated With Cultivated Switchgrass In Iowa, C. E. Gravert, G. P. Munkvold

Journal of the Iowa Academy of Science: JIAS

Switchgrass (Panicum virgatum L.) is a native perennial prairie grass that is now cultivated as a forage crop and a biomass crop for renewable energy. Biomass yields of switchgrass in southern Iowa have recently dropped significantly in some fields and the reduction has been attributed to disease. A disease survey was conducted in 1999 to assess the prevalence of major diseases in Chariton Valley switchgrass production. There were disease symptoms present on switchgrass plants in each field and thirteen fungal species were identified from leaf, stem, and root samples. Two pathogenic fungi, Tilletia maclaganii and Colletotrichum graminicola, were present in …

Book Review - Prairie Birds: Fragile Splendor In The Great Plains, Neil P. Bernstein

Journal of the Iowa Academy of Science: JIAS

Paul A. Johnsguard has established himself as one of the most prolific natural history writers in the recent past. Indeed, before I could finish reading Prairie Birds, the University of Kansas Press sent me The Nature of Nebraska, also by Johnsguard. These works follow closely after This Fragile Land, A Natural History of the Nebraska Sandhills (1995), which I favorably reviewed a few years ago, also about the Great Plains. It goes without saying, that there is a fair amount of overlap in these works, both in the subject matter and the illustrations. Rather than criticize the overlap among these …

The Unionid Mussels Of The Upper Iowa And Turkey River Watersheds, Jim Eckblad, Brett Ostby, Karis Tenneson

Journal of the Iowa Academy of Science: JIAS

The Iowa driftless region occupies an area of about 9,000 km² in the northeastern corner of Iowa and is drained by relatively old entrenched meandering streams. The Upper Iowa River and Turkey River are the largest of these streams. During the period from June, 1999 to October, 2000, a total of 193 sites were surveyed for mussels from the Upper Iowa River, the Turkey River, and their main tributaries. Surveys were conducted by hand using a 10 m bank-to-bank search at each site. Data analysis was facilitated using ArcView GIS. The presence of mussels was recorded at 75% of …

Animal Dissection And Evidence-Based Life-Science And Health-Professions Education, Nathan Nobis

Education Collection

Balcombe’s (2000, 2001) case for replacing learning methods that require pain, suffering, and death for animals with methods that do not (computer-assisted learning, three-dimensional models, videotapes, and other alternatives) can be seen as motivated by this evidentialist perspective. Balcombe provided a wealth of empirical evidence from educational studies to show that in most contexts animal dissection is not necessary—and even counterproductive—to achieve valid educational goals, especially higher order goals (concept learning and problem solving). He demonstrated that no sound defense of dissection has been given.

Identification And Distribution Of Masked And Hayden's Shrews (Genus Sorex) In Iowa, Howard P. Whidden, Alison W. Ray, John B. Bowles

Journal of the Iowa Academy of Science: JIAS

Masked shrews (Sorex cinereus) and Hayden's shrews (S. haydeni) are both reported from Iowa, but the two species are difficult to tell apart and their relative distributions in Iowa have been unclear. We took 13 skull measurements and examined 2 qualitative features on more than 300 specimens of Sorex from Iowa. The vast majority of our specimens could be identified easily by cranial measurements, and more than half could be identified by the relative position of the maxillary plate. We found no evidence for intergradation between the two species. Masked shrews are present throughout most of Iowa, whereas Hayden's shrews …
