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

Faculty Work

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.

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 levels …

Struggling Learners Of Mathematics: An Investigation Of Their Learning Through Reform-Based Instruction, Jennifer Pothast

Dissertations and Theses @ UNI

The purpose of this study was to explore mathematics instruction which implements reform-based problems within a traditionally taught classroom and its effect on struggling learners of mathematics. The reform-based problems implemented during the course of this study dealt with area and perimeter concepts at the fifth grade level. For this study, struggling learners of mathematics were defined as students scoring below the 40th percentile on the mathematics subtests of the Iowa Test of Basic Skills. The regular classroom teacher taught all lessons during the unit of instruction, while the researcher collected data from students using multiple methods: pretests and posttests, …

Dissertations and Theses @ UNI

This study sought to understand the process of change elementary teachers experienced as they participated in mathematics professional development. This investigation explored the impact of mathematics professional development on teachers' content knowledge for teaching, their ability to implement innovative pedagogical practices, and the relationship between these two components of teacher change. Data collected from a semester-long professional development course involving 20 teachers from rural southwest Iowa was analyzed for this study.

Data was collected from six teachers involved in the professional development course. Data collected during the professional development course included a pre and post test of teachers' content knowledge, …

Generativity: The New Frontier For Information And Communication Technology Literacy, Jorge Pérez, Meg C. Murray

Faculty Articles

Information and communication technology literacy is increasingly referred to as the fourth literacy. However, it is neither as well understood nor as readily assessed as reading, writing, and arithmetic. This paper argues that better understanding and more effective measurement of ICT literacy are needed to gauge readiness to both pursue higher education and enter the workforce. The paper builds on existing definitions of ICT literacy by introducing a model that extends the dimensionality of the construct. The model posits that skills and knowledge, along with attitudes toward IT, coalesce in the context of reflective self-awareness and purposeful intent to allow …

Gains In Knowledge And Perception Of Engineering After Participation In An Engineering Design Web-Experience Are Gender-Dependent, Kimberly Edginton Bigelow, Gail Wheatley, David Tomasko

Mechanical and Aerospace Engineering Faculty Publications

Web-based activities have the potential to teach engineering in both formal and informal science education settings, maximizing outreach efforts. To date, many activities available on the internet teach about engineering, but few allow students to truly “do” engineering.

This project utilized web animation and interaction in the design of a web-based experience focused on engineering design. In this activity, targeted toward middle school students, users played the role of engineer and engaged in the process of designing a cell phone for the older adult market. It was hoped that this web-based activity would increase participant understanding of what engineering is …

Clean Water In The Classroom : Understanding The Importance Of Water Quality , Emily Curry

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

This study’s objective was to answer three research questions related to students’ knowledge and attitudes about water quality and availability issues. It is important to understand what knowledge students have about environmental problems such as these, because today’s students will become the problem solvers of the future. If environmental problems, such as those related to water quality, are ever going to be solved, students must be environmentally literate.

Several methods of data collection were used. Surveys were given to both Bolivian and Jackson High School students in order to comparison their initial knowledge and attitudes about water quality issues. To …

Cosmological Beliefs About Origins Related To Science Achievement Among Junior High-School Students In South Bend, Indiana, J. David Van Dyke

Dissertations

Problem. American high-school students score lower in science achievement tests than their peers in other developed nations. The Organization for Economic Cooperation and Development (OECD) ranked the scientific achievement of American high-school students as ―very low‖ in comparison to high-school students in other industrialized nations—only 29th out of 57 developed countries. Research has indicated that achievement declines as U.S. students progress to higher grades and take on more rigorous science courses. A variety of factors have been documented that may account for U.S. students‘ lower science achievement rankings. These include socioeconomic status, race, and gender. One area only marginally …

The Impact Of Coteaching On Regular Education Eighth Grade Student Achievement On A Basic Skills Algebra Assessment, Misty B. Rigdon

Walden Dissertations and Doctoral Studies

Coteaching strategies have been implemented in many of the inclusion math classrooms in an attempt to improve the achievement of students. Math achievement continues to be a concern as reported by the National Mathematics Advisory Council in 2007. Educators and previous research reported that coteaching does not improve student achievement. The purpose of this study and the research question was designed to investigate, determine, and examine if coteaching has an impact on regular education students' achievement on an algebra assessment in the eighth grade. This concurrent mixed methods design used test data from a convenience sample of 70 eighth grade …

Professional Development In Elementary School Mathematics, C Scoggins

Walden Dissertations and Doctoral Studies

This study was an investigation of mathematics instruction and professional development at a rural elementary school. The Department of Education in a southern U.S. state implemented a new curriculum in 2007 that required major changes in mathematics instruction. The problems were that teachers engaged in different levels of training and many students experienced a decline in mathematics scores on the Criterion-Referenced Competency Test (CRCT). The historical learning theories of Piaget and Vygotsky framed the study. The guiding questions focused on how to improve mathematics instruction through professional development for teachers. Nine elementary school educators served as purposefully selected participants. The …

Research In Technology Education, Philip A. Reed (Editor), James E. Laporte (Editor)

STEMPS Faculty Books

Due to the laboratory-based nature of technology and engineering education programs, professionals in our field have often focused on the resources in our classrooms and laboratories and the instructional methodologies used to address specific concepts. Formal research into content and practice has often given way to “what seems right”. New curriculum is constantly being introduced (based on what is occurring in business and industry), yet the inclusion for those evolving concepts in courses and programs is typically not verified.

Hence, the importance of the 2010 CTTE yearbook and its focus on the dire need for an aggressive research agenda in …

Examining Sociocultural Contexts Of Classrooms To Foster Student Mathematical Discourse And Learning, Melva R. Grant

Teaching & Learning Faculty Publications

Mathematics learning and teaching are optimized in classrooms when reform-oriented culture (ROC) is present. This report presents a case study that illustrates how ROC manifested and influenced mathematical Discourses in one sixth-grade classroom. The data was drawn from a study that addressed the question: How do classroom interactions influence mathematical Discourses? The study used interpretive methodology for analysis. One finding was that classroom boundary interactions either enhanced or hindered mathematical Discourses dependent upon sociocultural context alignments. An implication of this research is when “effective” learning and/or teaching strategies are identified, “effective” implementation may require paying close attention to sociocultural context …
