How Eighth-Grade Students Estimate With Fractions, Audrey Linford Hanks

Theses and Dissertations

This study looked at what components are in student solutions to computational estimation problems involving fractions. Past computational estimation research has focused on strategies used for estimating with whole numbers and decimals while neglecting those used for fractions. An extensive literature review revealed one study specifically directed toward estimating with fractions (Hanson & Hogan, 2000) that researched adult estimation strategies and not children's strategies. Given the lack of research on estimation strategies that children use to estimate with fractions, this study used qualitative research methods to find which estimation components were in 10 eighth-grade students' solutions to estimation problems involving …

Robots That Teach: Developing An Integrated Curriculum For Middle School Math, Antoinette P. Bruciati

Education Faculty Publications

Keeping middle school students interested in mathematics and motivating them to succeed are challenges that continually present themselves to even the most seasoned teachers. Students will be drawn to mathematics if they are able to connect it to exciting careers. This paper describes a research-based curriculum model for teachers, grant writers, and others interested in incorporating Lego robotics technologies into an existing middle school mathematics curriculum. The model is based on data gathered from a three year research study in which approximately 150 sixth grade students per year and their teachers collaborated with a middle school Math Coordinator, a school …

Teaching High School Age Students With Special Needs The Four Situations For Subtraction, K. A. D. Miller, Audrey C. Rule, V. M. Macentee

Open Educational Resources

All learners, including those who qualify for special education services, should have access to learning mathematical concepts. This study examined the efficacy of using hands-on sets of materials to teach two high school students with mental retardation the four situations for subtraction. This is a mixed methods study using a simple pretest-posttest design to determine correct interpretation of subtraction story problems for different situations (take-away, comparison, completion, and whole-part-part) and correct regrouping during dynamic subtraction. Eight story problems were presented to the two participants eight weeks prior to instruction; students answered an identical posttest after twelve half-hour lessons on subtraction …

From College Prep High School Courses To College Remedial Courses : Bridging The Gap, Tracy K. Abar

Theses, Dissertations and Culminating Projects

This study investigated students’ use of, and access to, the calculator in high school mathematics courses and compared it to the accessibility of a calculator during college placement tests. In spring 1999, at the request of the College Board, the Educational Testing Service (ETS) conducted a survey on calculator use in the nation’s schools. Ninety-nine point nine percent of the schools surveyed indicated they either required or allowed calculators for part of their college preparatory mathematics sequence. Accompanying the increased role of calculators in mathematics learning and the use of technology in the classroom, significant changes were introduced into many …

Reorganizing Freshman Business Mathematics Ii: Authentic Assessment In Mathematics Through Professional Memos, Kris H. Green, W. Allen Emerson

Mathematical and Computing Sciences Faculty/Staff Publications

Part I of this paper described the development of a new Freshman Business Mathematics (FBM) course at our college. In this second part of the paper, we discuss our assessment tool, the business memo, as a venue for students to apply mathematical skills, via mathematical modeling, to realistic business problems. These memos have proven a crucial step in turning our FBM course around from a dreaded course with little connection to students’ intended careers into a course where students experience the power of mathematics for solving problems and informing decisions. Comments from students in the course throughout its six-year history …

Teacher As Designer: A Framework For Teacher Analysis Of Mathematical Model-Eliciting Activities, Margret A. Hjalmarson, Heidi Diefes-Dux

Interdisciplinary Journal of Problem-Based Learning

The study investigated tool development by three middle school mathematics teachers. The tools they designed were intended to support the use of model-eliciting activities (a form of instruction related to problem-based learning) and particularly the students’ presentations of their solutions for the whole class. The study examined the design and purposes for the presentation tools and resulted in a framework for categorizing teachers’ purposes for tools.The framework addressed the unit of analysis for the tools (individual students or groups of students) and the nature of teachers’ purposes for the tools. Design research was used as a theoretical perspective for conducting …

Dynamic Web Tools For Trigonometry, Steven J. Wilson

Innovations in Math Technology

In the last 20 years, computer technology having mathematical capability has been developed, improved, and become widely available, but textbook presentations are still largely free of any discussion that might require technology. Technology could be used in mathematical instruction for student drill and practice, for instructor demonstrations that promote conceptual understanding, or for the exploration of mathematical ideas, but software is often designed to be pedagogically generic, leaving its use to the creativity of the instructor. Technological solutions for local machines can be quite extensive, but cost and time constraints then limit availability for student use. The internet has the …

Promoting Student Collaboration In A Detracked, Heterogeneous Secondary Mathematics Classroom, Megan Staples

CRME Publications

Detracking and heterogeneous groupwork are two educational practices that have been shown to have promise for affording all students needed learning opportunities to develop mathematical proficiency. However, teachers face significant pedagogical challenges in organizing productive groupwork in these settings. This study offers an analysis of one teacher’s role in creating a classroom system that supported student collaboration within groups in a detracked, heterogeneous geometry classroom. The analysis focuses on four categories of the teacher’s work that created a set of affordances to support within group collaborative practices and links the teacher’s work with principles of complex systems.

A Descriptive Study Of The Impact Of Planning Time On The Utilization Of The National Council Of Teachers Of Mathematics Process Standards Within The Algebra 1 And Applied Mathematics Subject Fields, Kerri Colleen Lookabill

Theses, Dissertations and Capstones

Planning practices are necessary requirements for effective instruction. Their importance is illustrated in the guidelines produced by several national organizations such as The Interstate New Teacher Assessment and Support Consortium (INTASC), The National Board for Professional Teaching Standards (NBPTS), and The National Council of Teachers of Mathematics (NCTM). Planning time is considered important by teachers at the grassroots level in order for them to develop thought-provoking lessons that allow students to make connections and form meaning as well as to reflect on previous lessons in order to make improvements for subsequent lessons. Collaborative planning is also considered important; however, it …

We All Teach The Nature Of Science - Whether Accurately Or Not, Michael P. Clough

Iowa Science Teachers Journal

The phrase “nature of science” (NOS) is often used in referring to issues such as what science is, how it works, the assumptions underlying the doing of science, how scientists operate as a social group and how society itself both influences and reacts to scientific endeavors. These and many other thoughts regarding the NOS are informed by contributions from several disciplines including, but not limited to, the history, philosophy, sociology, and psychology of science.

Aerobic And Anaerobic Respiration: Inquiry Compared To Traditional Pedagogical Approaches, Sarah A. Sanderson, Tanya Gupta, Kimberly A. Penning

Iowa Science Teachers Journal

This article discusses and compares two approaches to teaching students about aerobic and anaerobic respiration. One approach was to have students take part in a common cookbook activity where a preset procedure is followed. In the second approach, students completed the same activity, th but in a more inquiry-oriented fashion. Each approach was implemented in two 10 grade classes. Students experiencing the inquiry approach were observed spending more time discussing the targeted concepts, and they performed better on the end-of-unit test. This article addresses National Science Education Standards A, C, and G and Iowa Teaching Standards 1, 2, 3, 4, …

Weapons Of Mass Instruction: The Teacher’S Crucial Role In Promoting A Deep Understanding Of Conservation Of Mass, Matthew Moffitt, Joseph Miller

Iowa Science Teachers Journal

Conservation of mass is a counter-intuitive idea that students struggle to fully comprehend (Stavy, 1990). This article presents a modified version of a conservation of mass demonstration. The original activity has much potential, but here we make clear the teacher's role that is necessary for promoting inquiry and deep mental engagement. We also discuss the use of several instructional “weapons” we have successfully used to enhance learning: questioning, wait time, listening, and nonverbal communication with students. We include numerous sample questions that we ask to encourage students to share their ideas, and help students come to the desired understanding. This …

Density With Intensity, Michelle State, Laurie Mcghee

Iowa Science Teachers Journal

This article presents a guided-inquiry activity where students apply their emerging understanding of density. Students are presented with the question of how different solids and liquids will arrange themselves when placed together. However students are not allowed to physically put them together. With teacher guidance and scaffolding, students determine that they can solve the problem by calculating and comparing the densities of the various substances. This activity would best be used in grades 8-12 in the application phase of the learning cycle, or modified to become a summative assessment for a density unit. This article also discusses the crucial role …

How "Bright" Is It To Use Cfls? A Look At The Controversy, Roxanne Greitz Miller

Education Faculty Articles and Research

Commonly referred to as CFLs, compact fluorescent light bulbs are rapidly replacing traditional incandescent light bulbs for residential use. However, controversy and even comic parody have arisen surrounding CFL use. CFLs contain small amounts of mercury, and several public forums and news agencies have been announcing that the breakage of a CFL in one's home may result in exposure to dangerously high mercury levels that can cause serious physical side effects. The purpose of this article is to introduce the basics of how incandescent and compact fluorescent light bulbs work, explain why the switch to CFLs is being promoted, and …

Mathematicians Playing A Role In Math Education: What We Learned At The Ime/Mime Workshop, Anna Bargagliotti, Rama Chidambaram, Gizem Karaali

Pomona Faculty Publications and Research

In Hollywood, some actors are regularly cast as mean, others as sweet and endearing, and some typically play innocent big-eyed youths who inevitably succeed after awakening to the particular facts of life that their producer wants them to awaken to. It is unusual and difficult for actors to cross the bridge between different types on a regular basis. However, there are always exceptions to the rule.

In the seemingly unrelated world of academics, mathematics faculty may find themselves playing different roles. People with different skills and interests strive to balance their careers in ways that will be uniquely fulfilling to …

Using Landscape History And Baseline Data In The Restoration Of A Midwestern Savanna, Andrew P. Rayburn, Annabel L. Major

Journal of the Iowa Academy of Science: JIAS

Over one hundred and fifty years of Euro-American settlement has dramatically altered Midwestern landscapes, resulting in the widespread conversion of native habitat. Numerous opportunities to conduct ecological restoration exist within the Midwest, with the potential to increase habitat and landscape heterogeneity, secure critical ecosystem services, and provide opportunities for research and education. Site history is an important consideration for most restoration projects, and multiple sources of historical data may be required to unravel the complicated history of intensively used Midwestern landscapes. The collection of baseline data is another significant component of most restoration projects, allowing for an evaluation of community …

Measuring Knowledge Of Natural Selection: A Comparison Of The C.I.N.S., An Open-Response Instrument, And An Oral Interview, Ross Nehm, Irvin Sam Schonfeld

Publications and Research

Growing recognition of the central importance of fostering an in-depth understanding of natural selection has, surprisingly, failed to stimulate work on the development and rigorous evaluation of instruments that measure knowledge of it. We used three different methodological tools, the Conceptual Inventory of Natural Selection (CINS), a modified version of Bishop and Anderson's (Bishop and Anderson [1990] Journal of Research in Science Teaching 27: 415-427) open-response test that we call the Open Response Instrument (ORI), and an oral interview derived from both instruments, to measure biology majors' understanding of and alternative conceptions about natural selection. We explored how these instruments …
