Beyond Problem-Solving: Elementary Students’ Mathematical Dispositions When Faced With The Challenge Of Unsolved Problems, Jenna R. O'Dell

Theses and Dissertations

The goal of this study was to document the characteristics of students’ dispositions towards mathematics when they engaged in the exploration of parts of unsolved problems: Graceful Tree Conjecture and Collatz Conjecture. Ten students, Grades 4 and 5, from an after-school program in the Midwest participated in the study. I focused on the cognitive, affective, and conative aspects of their mathematical dispositions as they participated in 7 problem-solving sessions and two interviews.

With regard to cognitive aspects of the students’ dispositions, I focused on the students attempts to identify and justify patterns for labeling graphs. Overall, the unsolved problems were ...

There is a need for an increase in the number of students entering fields of science, technology, engineering, and mathematics (STEM) and the only way for that to happen is for educational reforms to be put into place (PCAST, 2012). Improvement and focus on STEM education are a concern of all nations whether they have an emerging economy or one that is long established. The world of the 21st century is such that in order to compete globally countries must invest in STEM education (Kennedy & Odell, 2014). The United States scores on the Program for International Student Assessment (PISA) were ...


Contextualizing Developmental Math Content Into Introduction To Sociology In Community Colleges, Stuart Parker, Amy E. Traver, Jonathan Cornick 2017 CUNY Kingsborough Community College

Contextualizing Developmental Math Content Into Introduction To Sociology In Community Colleges, Stuart Parker, Amy E. Traver, Jonathan Cornick

Publications and Research

Across community colleges in the United States, most students place into a developmental math course that they never pass. This can leave them without the math skills necessary to make informed decisions in major areas of social life and the college credential required for participation in growing sectors of our economy. One strategy for improving community college students’ pass rate in developmental math courses is the contextualization of developmental math content into the fabric of other courses. This article reviews an effort to contextualize developmental math content (i.e., elementary algebra) into Introduction to Sociology at Kingsborough Community College and ...

Developing Mathematical Content Knowledge For Teaching Elementary School Mathematics, Eva Thanheiser, Christine A. Browning, Meg Moss, Tad Watanabe, Gina Garza-Kling

Eva Thanheiser

In this paper the authors present three design principles they use to develop preservice teachers' mathematical content knowledge for teaching in their mathematics content and/or methods courses: (1) building on currently held conceptions, (2) modeling teaching for understanding, (3) focusing on connections between content knowledge and other types of knowledge. The authors share results of individual research projects and teaching approaches focusing on helping preservice elementary teachers develop such knowledge. Specific examples from different content areas (whole number, fractions, angle, and area) are discussed.


Influence Of Reduced Leaching On Growth Of Seedlings Of Black Locust Inoculated With Rhizobia, William R. Graves, Sandra R. Anfinson 2017 Iowa State University

Influence Of Reduced Leaching On Growth Of Seedlings Of Black Locust Inoculated With Rhizobia, William R. Graves, Sandra R. Anfinson

William R Graves

Seedlings of black locust (Robinia pseudoacacia L.) were inoculated with compatible rhizobia and irrigated twice each week with solution containing either 50 or 150 mg nitrogen/L. Leaching fraction treatments of 0, 0.2, or 0.4 were maintained for 6 weeks. Seedlings supplied 50 mg nitrogen/L grew poorly compared co planes supplied 150 mg nitrogen/L regardless of leaching fraction. Dry masses of shoots and of entire planes were lower for seedlings in the 0 and 0.2 leaching fraction treatments compared with chose in the 0.4 treatment. Neither leaching fraction nor applied nitrogen concentration appeared co ...

Have Gender Gaps In Math Closed? Achievement, Teacher Perceptions, And Learning Behaviors Across Two Ecls-K Cohorts, Joseph R. Cimpian, Sarah T. Lubienski, Jennifer D. Timmer, Martha B. Makowski, Emily K. Miller

Emily Miller

Studies using data from the Early Childhood Longitudinal Study–Kindergarten Class of 1998–1999 (ECLS-K:1999) revealed gender gaps in mathematics achievement and teacher perceptions. However, recent evidence suggests that gender gaps have closed on state tests, raising the question of whether such gaps are absent in the ECLS-K:2011 cohort. Extending earlier analyses, this study compares the two ECLS-K cohorts, exploring gaps throughout the achievement distribution and examining whether learning behaviors might differentially explain gaps more at the bottom than the top of the distribution. Overall, this study reveals remarkable consistency across both ECLS-K cohorts, with the gender gap ...


The Effects Of Supplemental Instruction On Student Achievement In College Algebra, Rhonda C. Porter 2017 Albany State University

The Effects Of Supplemental Instruction On Student Achievement In College Algebra, Rhonda C. Porter

Georgia Journal of Science

College algebra consistently has a very high number of students performing poorly. An experimental study addressing student performance was conducted. Two college algebra classes each with 25 students and with the same teacher were used, one as the control group and the other as the experimental group. The experimental class included mandatory supplemental instruction for an extra class period per week. T-tests were used to compare performances on each test and homework. A repeated measures 2 X 2 ANOVA was used to compare the students' performance on a pretest and a posttest between each class. The Mann-Whitney U test was ...

Teachers’ Incorporation Of Argumentation To Support Engineering Learning In Stem Integration Curricula, Corey A. Mathis, Emilie A. Siverling, Aran W. Glancy, Tamara J. Moore

Journal of Pre-College Engineering Education Research (J-PEER)

One of the fundamental practices identified in Next Generation Science Standards (NGSS) is argumentation, which has been researched in P-12 science education for the previous two decades but has yet to be studied within the context of P-12 engineering education. This research explores how elementary and middle school science teachers incorporated argumentation into engineering design-based STEM (science, technology, engineering, and mathematics) integration curricular units they developed during a professional development program. To gain a better understanding of how teachers included argumentation in their curricula, a multiple case study approach was conducted using four STEM integration units. While evidence of argumentation ...

Journal of Pre-College Engineering Education Research (J-PEER)

An understanding of statistics and skills in data analysis are becoming more and more essential, yet research consistently shows that students struggle with these concepts at all levels. This case study documents some of the struggles four groups of fifth-grade students encounter as they collect, organize, and interpret data and then ultimately attempt to draw conclusions or make decisions based on these data. The activities in which the students engaged were part of an integrated science, technology, engineering, and mathematics (STEM) unit that had students collecting and analyzing data both in the context of learning science concepts and in the ...

Undergraduate Engineers And Teachers: Can Students Be Both?, Malinda S. Zarske, Maia L. Vadeen, Janet Y. Tsai, Jacquelyn F. Sullivan, Denise W. Carlson

Journal of Pre-College Engineering Education Research (J-PEER)

Today’s college-aged students are graduating into a world that relies on multidisciplinary talents to succeed. Engineering college majors are more likely to find jobs after college that are outside of STEM (science, technology, engineering, and mathematics) fields, including jobs in healthcare, management, and social services. A survey of engineering undergraduate students at the University of Colorado Boulder in November 2012 indicated a desire by students to simultaneously pursue secondary teacher licensure alongside their engineering degrees: 25 percent ‘‘agreed’’ or ‘‘strongly agreed’’ that they ‘‘would be interested in earning grades 7–12 science or math teaching licenses while [they] earn ...


Using “Tapestries” To Document The Collective Mathematical Thinking Of Small Groups, Alayne Armstrong 2017 University of Regina

Using “Tapestries” To Document The Collective Mathematical Thinking Of Small Groups, Alayne Armstrong

The Qualitative Report

A challenge in mathematics education research has been to document the complex nature of collective mathematical learning. This paper describes a method of data analysis that offers a visual representation of collective discourse during mathematical tasks. Using data extracts from a study of small groups in a middle years classroom, I color code collective utterances to create a “tapestry,” a type of transcript that offers researchers the ability to move between individual and collective planes of focus during analysis. The nature of collective thinking is revealed by tapestries, including how utterances bump against each other, the role of utterances evolves ...


Formative Assessment And Its Influence On Classroom Community In Biocalculus, Rebecca A. Dibbs, Daniel Rios, Brian Christopher 2017 Texas A&M University-Commerce

Formative Assessment And Its Influence On Classroom Community In Biocalculus, Rebecca A. Dibbs, Daniel Rios, Brian Christopher

The Qualitative Report

Most of the attrition from STEM majors occurs between the first two semesters of calculus, and prospective life science majors are one of the groups with the highest attrition rate. One of the largest factors for students that persist in STEM major beyond the first semester of calculus was a sense of community and a perceived connection with their instructor. Since building a sense of community is one of the stated purposes of formative assessment, we investigated how instructor and student perceptions of the purpose of formative assessment contributed to the formation of classroom community in a calculus for life ...

The Specific Surface Area Values For Iowa Tills, Keith E. Schilling, Brian L. Gedlinske

Brian Gedlinske

Specific surface area is a property used by earth scientists to estimate the proportion of expandable clay minerals in soils. In this study, specific surface area method is shown to compare favorably with standard clay mineralogical techniques in determining gross differences in expandable clay mineral content in tills. The results of over 100 measurements on till samples from Iowa indicate undifferentiated pre-Illinoian tills from southern and southwestern Iowa have the highest specific surface area values of Iowa tills (ranging from nearly 100 to greater than 150 m2/g) and Wisconsinan Dows Formation tills have the lowest average specific surface ...

Proof, Proving And Mathematics Curriculum, Thomas Varghese 2017 Northern Alberta Institute of Technology

Proof, Proving And Mathematics Curriculum, Thomas Varghese

Transformations

The National Council of Teachers of Mathematics, a US based teachers association, strongly encourages teachers to make proof and reasoning an integral part of student mathematics. However, the literature shows that, far from being integral, proving remains compartmentalized within the North American school curriculum and is restricted to a specific mathematical domain. Consequently, students suffer in their understandings and are ill prepared for the rigorous mathematical proving that many of them will encounter later at the postsecondary level. The literature suggests that compartmentalization is mainly due to teacher’s lack of experience in proof and proving and their subsequent inability ...

The Plight Of The Gifted Student: A Call To Action, Krista M. Shilvock

Empowering Research for Educators

With so many needs in today’s public education classroom, we cannot forget the needs of those who excel in the classroom, too. Gifted students face severe neglect in class due to the appearance of their competence and maturity. However, we quickly face losing the contributions of a major group of students as this neglect causes them to lose interest in their own education. As teachers, we must challenge ourselves to help gifted students reach their potential just as we attempt to do for all subgroups of students. A poll of 22 gifted students confirms these frustrations and needs of ...
