Mathematics Professional Development Workshop For Middle School Teachers: Concept Versus Memorization, D. Taylor, R. W. Farley

Journal of Mathematics and Science: Collaborative Explorations

This article includes professional development topics for middle school mathematics and science teachers from two week-long Urban Teacher Institutes. These Institutes were held at J. Sargeant Reynolds Community College (JSRCC) and its partner institution, Virginia Commonwealth University (VCU), during the summers of 2007 and 2008, and were supported by a grant obtained by Dr. Harriet Morrison (JSRCC). Co-author Dr. Dewey Taylor directed the 2007 workshop, and both authors served as faculty leaders in both workshops. The workshops focused on teaching in an urban environment and "community mapping" (understanding the details of a certain locale to make the teacher more knowledgeable …

Assimilative Domain Proficiency And Performance In Chemistry Coursework, Scott William Byrnes

Walden Dissertations and Doctoral Studies

The assimilation and synthesis of knowledge is essential for students to be successful in chemistry, yet not all students synthesize knowledge as intended. The study used the Learning Preference Checklist to classify students into one of three learning modalities -- visual, auditory, or kinesthetic (VAK). It also used the Kolb Learning Style Inventory (KLSI), which utilizes four learning domains - Converging, Accommodating, Diverging, and Assimilating - to explain the students' maturation process by showing shift from any domain towards the Assimilating domain. A shift approaching this domain was considered as improvement in the assimilation and synthesis of knowledge. This pre-experimental …

The Effect Of Cooperative Groups On Math Anxiety, Melissa Batton

Walden Dissertations and Doctoral Studies

Research indicates that many students have difficulty with mathematics, which can be attributed to many factors including math anxiety. Students who experience math anxiety have poor attitudes towards mathematics and perform below grade level based on class and statewide assessments. The purpose of this quasi-experimental quantitative study was to investigate the effectiveness of cooperative groups on the math anxiety levels of Grade 5 male and female students. The theoretical foundation of the study included Vygotsky's social learning and Piaget's concept of knowledge. Thirty-two students from 2 Grade 5 classrooms were administered the pre and post MASC inventory. A repeated-measure ANOVA …

The Price Of Inquiry: Managing Open-Inquiry Through Scaffolding And Faux Grant Writing, Shawn Cornally

Iowa Science Teachers Journal

Open-inquiry involves students asking their own questions, designing their own investigation, and creating their own explanations in order to learn about the natural world. However, implementing open-inquiry is often daunting for teachers and frustrating for students. This article discusses how I use guided inquiry to help students prepare for open-inquiry and a faux grant process to manage open-inquiry in my class. This activity promotes National Science Education Content Standards A, B, E, G, and Iowa Teaching Standards 1, 2, 3, 4, 5, and 6.

When Dissatisfaction Is A Good Thing, Michael P. Clough, Jerrid Kruse

Iowa Science Teachers Journal

Our previous editorial (Clough and Kruse, 2010) in the Iowa Science Teacher Journal used conceptual change theory (Posner, 1982; Pintrich et al., 1993; Abd-El-Khalick & Akerson, 2004; Clough, 2006) to highlight the similarities between students learning science content and educators learning to teach well. An important part of conceptual change is first acknowledging and then confronting current ways of thinking. That is, before learners (whether children or adults) will consider altering their thinking, they must first develop some sense of dissatisfaction with their currently held ideas. That can be difficult because the ideas people hold do appear to work — …

Temperature Rising: Investigating Rates Of Temperature Change, Jacob Norlin, Daryl Miller

Iowa Science Teachers Journal

This exploratory activity, designed for secondary physical science or earth science students, investigates rates of temperature change over bodies of water and land. Students discuss temperature trends of several cities across the United States, which creates an opportunity to conduct classroom experiments to explain these trends. Students write procedures and generate data of temperature changes between areas of water and land. Students gain a valuable, concrete experience of temperature changes which in turn enables them to better understand and explain why similar cities experience vastly different temperature patterns. This activity can then serve as a basis to address the abstract …

Confronting Doubts About The Intelligibility, Plausibility, And Fruitfulness Of Inquiry-Based Instruction, Jerrid Kruse, Michael P. Clough

Iowa Science Teachers Journal

Our two prior ISTJ editorials in the Iowa Science Teacher Journal (Clough & Kruse, 2010a & 2010b) have applied a conceptual change framework (Posner, Strike, Hewson & Gertzog, 1983; Pintrich et al., 1993; Abd-El-Khalick & Akerson, 2004; Clough, 2006a) to understand the difficulties students have in abandoning their intuitive ideas about the natural world and, for the same reasons, the difficulties teachers have in jettisoning their intuitive and learning. Our last editorial noted that in both cases, dissatisfaction with prior ways of thinking must be achieved before alternative ways of thinking will be seriously sought and considered. To initiate a …

Pulling Students In: Creating Concrete Experiences Through A Simple Pulley Device, Joe Kohlhaas, Teresa Morales

Iowa Science Teachers Journal

Physics is often taught with an emphasis on mathematical relationships. Many teachers use equations to teach, assuming that the content will fall into place. In reality, all students benefit from concrete representations and familiar objects and properties before learning abstractions (Karplus, 1977). Since mathematics is inherently abstract it must be reserved until after students have a firm conceptual understanding. This article provides a concrete activity that encourages students to explore pulleys. This activity promotes National Science Education Content Standards A, B, E, and F. It also addresses Iowa Teaching Standards 1, 2, 3, 4, and 5.

How Does Water Become Polluted? Helping Elementary Students Learn How To Prevent Pollution, Kelsey Bentzinger, Lindsey Thilges, Ken Vacek

Iowa Science Teachers Journal

Through making observations of mixing various items with water, students develop ideas about how pollution happens. The cumulative effect of what happens when many people add only “a little something” to the water provides students with a concrete representation of what can happen in their own communities. Students complete the lesson by determining what they can do to prevent pollution from happening in their own communities. This activity promotes National Science Education Content Standards A, B, and F, and Iowa Teaching Standards 1, 2, 3, 4, 5, and 6.

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

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

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

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.
