Exploring Teachers’ Beliefs And Practices On Mathematical Discourse For Diverse Students In Inclusive Classrooms, Gloria A. Carcoba Falomir
Exploring Teachers’ Beliefs And Practices On Mathematical Discourse For Diverse Students In Inclusive Classrooms, Gloria A. Carcoba Falomir
UNLV Theses, Dissertations, Professional Papers, and Capstones
The recent implementation of rigorous standards in mathematics education has required shifts in classroom practices. Standards-based instruction places large emphasis on students’ conceptual understanding, requiring them to demonstrate high cognitive levels of mastery of the content through communication of their mathematical reasoning. Teachers and students’ mathematical discursive practices in the classroom can lead to meaningful discussions that integrate students’ explanation, justification, and arguments of ideas or claims and understanding of the content. Research on teachers’ discursive practices has shown that (a) teacher talk tends to dominate classroom instruction and (b) classroom discourse lacks frequent opportunities for teacher-student and peer interactions. …
Positive Solutions To Semilinear Elliptic Equations With Logistic-Type Nonlinearities And Harvesting In Exterior Domains, Eric Jameson
Positive Solutions To Semilinear Elliptic Equations With Logistic-Type Nonlinearities And Harvesting In Exterior Domains, Eric Jameson
UNLV Theses, Dissertations, Professional Papers, and Capstones
Existing results provide the existence of positive solutions to a class of semilinear elliptic PDEs with logistic-type nonlinearities and harvesting terms both in RN and in bounded domains U ⊂ RN with N ≥ 3, when the carrying capacity of the environment is not constant. We consider these same equations in the exterior domain Ω, defined as the complement of the closed unit ball in RN , N ≥ 3, now with a Dirichlet boundary condition. We first show that the existing techniques forsolving these equations in the whole space RN can be applied to the exterior domain with some …

The purpose of this study was to explore the numeracy skills required for safe, quality nursing practice. Using a descriptive mixed methods design, this study answered two research questions: 1) What numeracy skills do nurses perceive as important for providing safe, quality nursing care in the first three years of practice? 2) How do nurses incorporate numeracy skills into daily patient care during the first three years of practice? Early career nurses from a not-for-profit health care organization in the mid-Atlantic region of the United States (n=109) responded to an online survey tool developed by the student investigator that ranked …
A Quasi-Classical Logic For Classical Mathematics, Henry Nikogosyan
A Quasi-Classical Logic For Classical Mathematics, Henry Nikogosyan
Honors College Theses
Classical mathematics is a form of mathematics that has a large range of application; however, its application has boundaries. In this paper, I show that Sperber and Wilson’s concept of relevance can demarcate classical mathematics’ range of applicability by demarcating classical logic’s range of applicability. Furthermore, I introduce how to systematize Sperber and Wilson’s concept of relevance into a quasi-classical logic that can explain classical logic’s and classical mathematics’ range of applicability.
Dual Task Interference In Low-Level Abilities: The Role Of Working Memory And Effects Of Mathematics Anxiety, Alex Michael Moore
Dual Task Interference In Low-Level Abilities: The Role Of Working Memory And Effects Of Mathematics Anxiety, Alex Michael Moore
UNLV Theses, Dissertations, Professional Papers, and Capstones
Mathematics anxiety is a negative affective reaction to situations involving mathematical thought and is commonly believed to reduce cognitive functioning by impairing the efficient use of working memory resources. The conventional theory describes that the processing disadvantage associated with high levels of math anxiety increasingly impairs performance as working memory demands increase in a math task. Despite this convention, recent reports demonstrate that the high math anxious disadvantage can be measured in tasks that are relatively free of working memory assistance (Maloney, Ansari, & Fugelang, 2011; Maloney, Risko, Ansari, & Fugelsang, 2010). The present study examines these relatively low level …

Effects Of Explicit Subtraction Instruction On Fifth Grade Students With Learning Disabilities, Danielle Ferreira
UNLV Theses, Dissertations, Professional Papers, and Capstones
This study involved an investigation of the effects of strategy instruction integrated with the concrete-representational-abstract teaching sequence on students with learning disabilities. A multiple probe design across subjects with one replication was used in this study. Two sets of data were analyzed to determine effectiveness of the independent variable (intervention lessons). The first data set consisted of pre and posttest percentage scores and the second data set consisted of baseline, intervention, and maintenance probe scores that were collected throughout the study per the parameters of a multiple probe design. The probe scores were plotted in line graph format and analyzed …
German Mathematics Teachers' Subject Content And Pedagogical Content Knowledge, Teresa A Leavitt
German Mathematics Teachers' Subject Content And Pedagogical Content Knowledge, Teresa A Leavitt
UNLV Retrospective Theses & Dissertations
How required teacher knowledge is obtained is debated in today's educational context. This dichotomy in acquisition of teacher knowledge between university training including content and pedagogy versus classroom experiences combined with strong subject background has become particularly important as the U.S. seeks to find key components to increase student achievement and to improve education. International comparisons indicating the U.S. consistently lags behind top-performing countries have spurred such efforts; Review of existing literature exposed differences in what is considered necessary knowledge for effective teaching, and where such knowledge can be developed. Types of knowledge and where such knowledge is acquired are …
Exploring The Relationship Between Teachers' Beliefs In Mathematics And Their Instructional Practice, Michelle Vander Veldt
Exploring The Relationship Between Teachers' Beliefs In Mathematics And Their Instructional Practice, Michelle Vander Veldt
UNLV Retrospective Theses & Dissertations
This study explored the relationship between teachers' beliefs about mathematics and their instructional practices. The personal epistemology of the case study elementary mathematics teachers was documented and analyzed to provide evidence of the connection between teachers' beliefs and practice in an elementary school setting; This study was grounded in a theoretical framework of epistemological world views, particularly the comparison of belief across three epistemological world views: (1) the realist, (2) the contextualist, and (3) the relativist. Three areas of beliefs are addressed in this study: (1) beliefs about curriculum, (2) beliefs about pedagogy, and (3) beliefs about assessment. Through analysis …
Pre-Service Secondary Mathematics Teachers' Attitudes About The History Of Mathematics, Kelly Marie Sullivan
Pre-Service Secondary Mathematics Teachers' Attitudes About The History Of Mathematics, Kelly Marie Sullivan
UNLV Retrospective Theses & Dissertations
This study was conducted to show that using historical material to teach mathematical content to pre-service secondary mathematics teachers could improve their attitudes about incorporating the history of mathematics into the mathematics classroom. A historical module from the Mathematical Association of America was taught to an undergraduate class of pre-service secondary mathematics teachers. Their attitudes regarding the use of the history of mathematics in the mathematics classroom were then compared to the attitudes of students in another undergraduate class, taught by the same researcher, whose instruction did not incorporate history. Results from t-tests indicate that there was a positive change …

UNLV Retrospective Theses & Dissertations
Vertical equating of a large urban school district's curriculum-based achievement tests for students in grades one through five was performed by using the BILOG-MG software package produced by Zimowski, Muraki, Mislevy, and Bock. This software extends the application of the item response theory (IRT) approach to test analysis to testing situations involving multiple groups BILOG-MG, item parameter estimates were derived using a marginal maximum a posteriori approach in combination with an expectation-maximization algorithm (EM). Estimates of examinee ability were produced using the Bayesian, or expected a posteriori, estimate with a normal prior distribution; Linkage of successive test forms was accomplished …
Attitudes And Beliefs Of Preservice Elementary School Teachers Towards Mathematics, Deborah Beam Ingalls
Attitudes And Beliefs Of Preservice Elementary School Teachers Towards Mathematics, Deborah Beam Ingalls
UNLV Retrospective Theses & Dissertations
This study purposed to see if measurable changes could be detected in prospective teachers' attitudes or beliefs about mathematics as teachers progressed through their required courses of study in mathematics and mathematics education. The study included 164 prospective elementary school teachers who were enrolled in one of three mathematics or mathematics education courses. The subjects responded to a survey based on common "mathematics myths." The mathematics myths correspond to mathematical beliefs shown in other research to be held by severely math anxious or math avoidant people. The study found that students disagreed more with the mathematics myths as they progressed …

The Effects Of A Role Model Intervention Program On The Attitudes Of Junior High School Students Towards Mathematics And Sex-Role Orientation, Linda Fritz Havins
The Effects Of A Role Model Intervention Program On The Attitudes Of Junior High School Students Towards Mathematics And Sex-Role Orientation, Linda Fritz Havins
UNLV Retrospective Theses & Dissertations
Bureau of Labor Statistics information indicated 55 percent of all women in the labor force in 1980 were employed in traditional clerical and service occupations. The limited participation of women in certain sectors of the labor force represented a great loss of human potential, particularly in the case of academically talented women. This exploratory study focused on two potential barriers that may keep capable women from realizing their full potential: sex-role orientation and attitudes toward mathematics course-taKing Another area of focus determined what effect stability factors had on the population under study and how stability might affect future studies. A …
