The Occurrence Of Chestnut Lamprey (Lchthyomyzon Castaneus; Pisces: Petromyzontidae) In The Chariton River In South-Central Iowa, Mark K. Flammang, John R. Olson Jan 2010

The Occurrence Of Chestnut Lamprey (Lchthyomyzon Castaneus; Pisces: Petromyzontidae) In The Chariton River In South-Central Iowa, Mark K. Flammang, John R. Olson

Journal of the Iowa Academy of Science: JIAS

In the mid-1990s, Iowa Department of Natural Resources (IDNR) Fisheries Bureau biologists began receiving reports from anglers of a parasitic lamprey attached to fish taken immediately downstream from Rathbun Lake on the Chariton River in south-central Iowa; these reports have continued to present. In 2002, the IDNR received and identified a chestnut lamprey (Ichthyomyzon castaneus Girard) from an angler who removed the lamprey from a common carp (Cyprinus carpio Linnaeus) he captured. This record was the first for a lamprey from the Chariton River drainage in Iowa. Five additional specimens of chestnut lamprey have been collected and identified …

Mammal Capture Success Of Scent Stations And Remote Cameras In Prairie And Forest Habitat, Marc N. Mckinney, Aaron M. Haines Jan 2010

Mammal Capture Success Of Scent Stations And Remote Cameras In Prairie And Forest Habitat, Marc N. Mckinney, Aaron M. Haines

Journal of the Iowa Academy of Science: JIAS

Two common noninvasive (i.e., no stress to the animal) methods used to survey mammals include track stations (i.e., track captures of mammals) and remote camera-traps (i.e., photo-captures of mammals). Our objectives were to compare capture effectiveness of both track stations and remote cameras in both forested and prairie habitats. This project was conducted on 4 study sires (2 forested sires and 2 prairie sites) located in Fayette County, Iowa. Each study site had 6 trapping stations 2:: 100 m apart. We monitored traps for a total of 216 trap nights and we recorded a total of 368 captures composed of …

The Vascular Flora Of Boone County, Iowa (2005-2008), Jimmie D. Thompson Jan 2010

The Vascular Flora Of Boone County, Iowa (2005-2008), Jimmie D. Thompson

Journal of the Iowa Academy of Science: JIAS

A vascular plant survey of Boone County, Iowa was conducted from 2005 to 2008 during which 1016 taxa (of which 761, or 75%, are native to central Iowa) were encountered (vouchered and/or observed). A search of literature and the vouchers of Iowa State University's Ada Hayden Herbarium (ISC) revealed 82 additional taxa (of which 57, or 70%, are native to Iowa), unvouchered or unobserved during the current study, as having occurred in the county. This total of 1098 taxa (979 species, 57 varieties, 39 subspecies, 23 hybrids) places Boone County first in vascular plant richness among 18 published county inventories …

Mathematical Notation: Help Or Hindrance?, Geoff D. Tennant Dr Jan 2010

Mathematical Notation: Help Or Hindrance?, Geoff D. Tennant Dr

Institute for Educational Development, East Africa

This article puts forward a range of reasons for using mathematical notation, emphasizing the need to allow children learning it time and space to come to terms with it. Examples are given in furthering the argument that the time to introduce notation is after the concept is already fully understood.

Preservice Secondary School Mathematics Teachers' Subject Matter Knowledge Of Perimeter And Area., Wun Thiam Yew Jan 2010

Preservice Secondary School Mathematics Teachers' Subject Matter Knowledge Of Perimeter And Area., Wun Thiam Yew

Student Works (2010-2019)

The purpose of this study was to investigate preservice secondary school mathematics teachers (PSSMTs)' subject matter knowledge (SMK) of perimeter and area. Specifically, this study aimed to investigate PSSMTs’ five basic types of knowledge of perimeter and area, namely conceptual knowledge (CK), procedural knowledge (PK), linguistic knowledge (LK), strategic knowledge (SK), and ethical knowledge (EK). This study also aimed to investigate PSSMTs' levels (low, medium, high) of SMK of perimeter and area. Data of this study was collected using clinical interview technique. Interview sessions were recorded using digital video camera and tape recorder. Subjects of this study consisted of eight …

Teaching Teachers And Students About The Nature Of Science, Nelofer Halai Jan 2010

Teaching Teachers And Students About The Nature Of Science, Nelofer Halai

Institute for Educational Development, Karachi

This article advocates the teaching about the nature of science to both pupils in schools and teachers in teacher education institutions in Pakistan. Not knowing about science; teachers tend to continue to teach science as fixed knowledge and not as inquiry and this cycle continues. This cycle needs to be broken. This article first discusses the salient features about the concept of the nature of science and then illustrates these ideas with the help of a simple but a powerful activity which could be used both with teacher educators and pupils in secondary and lower secondary classrooms.

Understanding The Transition Between High School And College Mathematics And Science, S. A. Culpepper, C. Basile, C. A. Ferguson, J. A. Lanning, M. A. Perkins Jan 2010

Understanding The Transition Between High School And College Mathematics And Science, S. A. Culpepper, C. Basile, C. A. Ferguson, J. A. Lanning, M. A. Perkins

Journal of Mathematics and Science: Collaborative Explorations

Mathematics and science education is gaining increasing recognition as key for the well-being of individuals and society. Accordingly, the transition from high school to college is particularly important to ensure that students are prepared for college mathematics and science. The goal of this study was to understand how high school mathematics and science course-taking related to performance in college. Specifically, the study employed a nonparametric regression method to examine the relationship between high school mathematics and science courses, and academic performance in college mathematics and science courses. The results provide some evidence pertaining to the positive benefits from high school …
