Faculty Publications

Using technology tools in math instruction can help stimulate problem-solving skills and understanding of math concepts. However, teachers need to be confident in their abilities to use technology tools. This study investigated whether or not a four-week in-service professional development institute that addressed the use of technology in math education helped improved the teachers’ attitude and confidence in applying technology. Findings indicated that as the teachers explored and used the available technology tools relevant to math instruction during the institute, the more proactive and motivated they became to continue their professional development in using technology for classroom instruction. They realized ...

Academic Success For Stem And Non-Stem Majors, Donald F. Whalen, Mack C. Shelley

Political Science Publications

Enrollment in STEM majors has improved recently, but there continues to be concern over retention in those majors, especially of women and minority students. The purpose of this study is to develop an integrated understanding of how multiple predictor variables affect student degree attainment and to ascertain how the variables impact is regulated by whether students are in STEM or non-STEM majors. Six-year cohort retention/graduation outcomes are predicted for all students in STEM and non-STEM majors, and are adjusted separately for whether students remain in, or shift into or away from, STEM majors. Long-term retention/graduation is predicted significantly ...

Meaningful Distributed Instruction— Conceptual Previews For Symbolic Procedures, Edward C. Rathmell 2010 University of Northern Iowa

Meaningful Distributed Instruction— Conceptual Previews For Symbolic Procedures, Edward C. Rathmell

Faculty Publications

Understanding a symbolic procedure means far more than “getting the right answer.” A mathematical symbolic procedure or written skill involves step-bystep thinking that leads from a computational problem to a solution. Memorizing this step-by-step procedure may enable a student to answer the problem, even answer it correctly. Yes, that is important, but understanding means much more.


Matching Functions And Graphs At Multiple Levels Of Bloom’S Revised Taxonomy, Kris H. Green 2010 St. John Fisher College

Matching Functions And Graphs At Multiple Levels Of Bloom’S Revised Taxonomy, Kris H. Green

Mathematical and Computing Sciences Faculty/Staff Publications

This paper illustrates the power of Bloom's revised taxonomy for teaching, learning and assessing [3] in aligning our curriculum expectations and our assessment tools in multivariable calculus. The particular assessment tool considered involves a common matching problem to evaluate students' abilities to think about functions from graphical and formulaic representations. Through this analysis we gain additional understanding of why students may have difficulty in performing well on certain activities.


If Mowat And Davis Are Correct, Then Teaching Is Hard: A Response To Elizabeth Mowat & Brent Davis, Kris H. Green, Bernard P. Ricca 2010 St. John Fisher College

If Mowat And Davis Are Correct, Then Teaching Is Hard: A Response To Elizabeth Mowat & Brent Davis, Kris H. Green, Bernard P. Ricca

Mathematical and Computing Sciences Faculty/Staff Publications

In lieu of an abstract, below is the article's first paragraph.

Mowat & Davis (this issue) present a model of learning mathematics that relies heavily on ideas from network (or graph) theory. The important questions (to us, at least) concern the dynamics of the nodes and links. Answers – even tentative ones such as we present here – to these questions lead to a second set of questions concerning the implications of these answers to teachers and researchers.


Intonation And Compensation Of Fretted String Instruments, Gabriele U. Varieschi, Christina M. Gower 2010 Loyola Marymount University

Intonation And Compensation Of Fretted String Instruments, Gabriele U. Varieschi, Christina M. Gower

Physics Faculty Works

We discuss theoretical and physical models that are useful for analyzing the intonation of musical instruments such as guitars and mandolins and can be used to improve the tuning on these instruments. The placement of frets on the fingerboard is designed according to mathematical rules and the assumption of an ideal string. The analysis becomes more complicated when we include the effects of deformation of the string and inharmonicity due to other string characteristics. As a consequence, perfect intonation of all the notes on the instrument cannot be achieved, but complex compensation procedures can be introduced to minimize the problem ...


Investigating Instructors' Conceptions Of Evolution Through The Development Of The Classroom Test Of Evolutionary Reasoning, Patricia Eileen Palko 2010 University of Denver

Investigating Instructors' Conceptions Of Evolution Through The Development Of The Classroom Test Of Evolutionary Reasoning, Patricia Eileen Palko

Electronic Theses and Dissertations

In order to assess the evolutionary understanding of high school biology teachers, an instrument entitled the Classroom Test of Evolutionary Reasoning (CTER) was developed. Content, response process, relations to another variable (the Conceptual Inventory of Natural Selection, or CINS), and internal structure evidence were compiled. The second version of the CTER was found to have adequate reliability and validity estimates to allow it to continue to be used as a measurement tool for an understanding of evolution. When assessing a sample of teachers (n = 724), the mean score was 6.35 out of a possible 13 points. The sample was ...


Trends In Environmental Concern By Grade Level: A Study Of Elementary, Middle, And High School Students, Ryan David Lensing 2010 University of Northern Iowa

Trends In Environmental Concern By Grade Level: A Study Of Elementary, Middle, And High School Students, Ryan David Lensing

Dissertations and Theses @ UNI

Environmental concern has been frequently measured since the 1970's, however, much of this research has focused on adults. Of the studies that look at students, the majority focus on high school with little attention given to middle or elementary grades. None of these studies have looked at elementary, middle, and high school students from the same population. This study uses the NEP Scale for Children in conjunction with free response questions to examine the trends in environmental concern from 120 Catholic elementary, middle school, and high school students from Des Moines, Iowa. The findings show no significant differences in ...

Teaching And Aligning Upper Level Mathematics Classes To Michigan High School Content Expectations In An Alternative Education Setting : Approaches And Issues, Sarah Van Baale

Dissertations, Master's Theses and Master's Reports - Open

After teaching regular education secondary mathematics for seven years, I accepted a position in an alternative education high school. Over the next four years, the State of Michigan adopted new graduation requirements phasing in a mandate for all students to complete Geometry and Algebra 2 courses. Since many of my students were already struggling in Algebra 1, getting them through Geometry and Algebra 2 seemed like a daunting task. To better instruct my students, I wanted to know how other teachers in similar situations were addressing the new High School Content Expectations (HSCEs) in upper level mathematics. This study examines ...


Cooperation Between Science Teachers And Esl Teachers: A Register Perspective, Tammy Slater, Bernard Mohan 2010 Iowa State University

Cooperation Between Science Teachers And Esl Teachers: A Register Perspective, Tammy Slater, Bernard Mohan

English Publications

Cooperation between English as a second or other language (ESOL) and content-area teachers, often difficult to achieve, is hard to assess linguistically in a revealing way. This article employs register analysis (which is different from, but complementary to, genre analysis) in a Systemic Functional Linguistic perspective to show how an ESOL teacher uses the same content-area task as a cooperating science teacher so that she can provide a theory–practice cycle similar to that of the science teacher, but at a level that reflects and builds on the language abilities of her students. The task allows her to assess her ...

Conceptual Change: It’S Not Just For Teaching Science, Michael P. Clough, Jerrid Kruse 2010 Iowa Academy of Science

Conceptual Change: It’S Not Just For Teaching Science, Michael P. Clough, Jerrid Kruse

Iowa Science Teachers Journal

Mark Twain is often given credit for saying, “It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so.” Science teachers likely resonate with this quote because we know our students come to class confidently holding many ideas about the natural world that “just ain't so.”

Thinking On Paper: Using Science Notebooks To Increase Active Engagement In The Elementary Science Classroom, Kimberly R. Gasaway 2010 Davenport Community School District

Thinking On Paper: Using Science Notebooks To Increase Active Engagement In The Elementary Science Classroom, Kimberly R. Gasaway

Iowa Science Teachers Journal

The need for scientific literacy is becoming a new standard to which school districts are being held accountable. Student inquiry and the ability to “think like a scientist” will increase the depth at which students understand the natural world and make connections that are critical in strengthening students' scientific literacy. In addition, research has shown that when students were actively engaged in the learning process, they participated more enthusiastically and retained the concepts being taught. Science notebooks help students learn to record and make sense of data and observations about the natural world and come to deeper understanding of scientific ...
