La Diversidad De Los Análisis De Diversidad La Diversidad De Los Analisis De Diversidad [The Diversity Of Diversity Analyses], Victor D. Carmona-Galindo, Tizziana V. Carmona

Biology Faculty Works

There is a lack of consistency with respect to the use of the terms like species richness, diversity and biodiversity, which extends to the analysis of diversity indices and the merit of using diversity indices in the evaluation (comparison and contrast) of biological communities. The purpose of this article is to provide working definitions for these terms and cite examples from the primary literature that demonstrate the utility of estimating richness, evaluating proportional abundance patterns, as well as comparing indices of diversity and similarity to study patterns of biological organization at different ecological scales. Additionally, we provide a manual in …

Corals On Acid: An Inquiry-Based Activity Leading Students To A Better Understanding Of Ocean Acidification Impacts, Casey L. Boleman, Philip M. Gravinese, Ellen N. Muse, Andrea E. Marston, John G. Windsor

Ocean Engineering and Marine Sciences Faculty Publications

The objective of this inquiry-based lesson is for students to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms. During this activity, students: (1) design an experiment to quantify the CaCO3 concentration of two invertebrate skeletal samples, one that has been soaked in normal seawater and another in a low pH solution, and (2) use critical thinking and discussion to evaluate possible explanations for the difference in the skeletal CaCO3 compositions. Our lesson focuses on exploring the activity before ocean acidification is introduced to provide a common conceptual framework to engage students.

Mathematics Interventions: A Correlational Study Of The Relationship Between Level Of Implementation Of The Accelerated Math Program And Student Achievement, Deborah Walker Driesel

Kindergarteners' Concept Development In Science And Literacy Learning Through Concept-Oriented Reading Instruction (Cori), Char Adelia Moffit

UNLV Theses, Dissertations, Professional Papers, and Capstones

The notion that "real work" is somehow different from authentic and engaging discovery is troublesome. (Passman, 2001, p.196)

This qualitative case study examined science concept and literacy learning along with engagement of the students in a Kindergarten class in which science and literacy instruction was integrated through Concept-Oriented Reading Instruction (CORI). CORI is an instructional framework created to increase reading engagement by teaching reading comprehension strategies along with science concepts (Guthrie, et al., 1996). This study explored CORI at the Kindergarten level to examine how this curriculum framework engaged young learners in science concept and literacy learning. The study was …

Elements: Elementary Teachers Of Science – Building Collaborations Between Content And Pedagogy Communities, Krista Adams, Jenny Melander

Discipline-Based Education Research Group Speaker Series

The current UNL elementary teaching program does not include a science methods practicum in which pre‐service elementary teachers could observe and teach reformed based science lessons in the classroom setting. The science methods course was modified during Spring 2013 to address this missing component. The exploratory course engages pre‐service teachers in designing and implementing a science unit (a series of lessons) to be taught as a science club in an after school program for K – 5th grade students. In Fall 2013, the course experiences expanded to include collaborating with biomedical engineering students in connecting real‐world applications to teaching science. …

Skills Needs Of The Ict Sector In Tanzania, Deirdre Lillis, Fredrick Mtenzi, Diana Mauricaite, Said Jafari, Peter Manifold

Reports

Information and Communication Technology will play a critical role in sustaining the high growth rates experienced by African economies in the last decade. Investment in the ICT sector enables the creation of high quality jobs and acts as an enabling technology for other key industries such as agriculture, mining, finance, health and education. ‘New Software Economy’ models mean international location and company scale are less relevant and enable small organisations to compete globally in niche markets. Unlike many traditional industries which have heavy infrastructure requirements, the key resource of the ICT Sector is its people and the knowledge, skills and …

Cave And Climate Change: Educating The Public At Rats Nest Cave, Alberta, Canada, Charles J. Yonge, Andrea Corlett, Adam Walker

National Cave and Karst Management Symposium 2013

Rats Nest Cave is a Provincial Historic Site whose mandate is to present its natural history to the public. In addition to a suite of interpretive messages, and relevant to this conference’s topic, we have addressed diverse climate change over the geological history of the cave. We start with the cave-hosting rock and the fossils it contains, to its origin along a thrust fault, ending with its enlargement and secondary mineralization during the Quaternary glaciations (the latter having been dated by radiometric methods). We have undertaken a program of speleothem remediation which, visible to the public, serves to reinforce the …

Broadening What We Perceive: A Method For Analyzing Gesture And Language, Caro C. Williams-Pierce

Mathematics and Statistics Faculty Scholarship

Gesture and language are deeply intertwined, and attending to both simultaneously when examining mathematical processes is a complex yet rewarding task. We share our budding research methodology for analyzing gesture and language and discuss the methodology from a generic perspective that can be easily adapted to different contexts, participants, and mathematical domains. We further share our problem-specific gesture coding scheme as an example of the grain size and foci of such schemes. Finally, we close by discussing the importance of gesture and language to understanding mathematical justifications and proofs.

Strategically Chosen Examples Leading To Proof Insight: A Case Study Of A Mathematician’S Proving Process., Caro C. Williams-Pierce

Mathematics and Statistics Faculty Scholarship

Examples play a critical role in the exploration and proving of conjectures. Although proof has been studied extensively, the precise ways in which examples might facilitate successful proofs are not well documented or understood. Working within a larger set of studies that argue for the value of examples in proof-related activity, in this paper we present a case study of one mathematician’s work on a conjecture in which his strategic, intentional use of examples led to a proof of that conjecture. By examining his work in detail, we highlight specific mechanisms by which the mathematician’s examples led to successful proof …

Physics Portfolios: A Picture Of Student Understanding, Brooke A. Whitworth, Randy L. Bell

Publications

Traditionally, teachers assess students' physics understanding through lab activities, responses to open-ended word problems, and tests. But there's another way to measure student understanding, one in which students apply their learning to the world around them. This article shows how to implement student portfolios, which allow students to set goals they can monitor throughout the year and actively participate in assessment. When students build portfolios, they can evaluate and reflect on their own work, promoting engagement with the course and content (Danielson and Abrutyn 1997), and teachers can better assess students' goal movement and see growth in students' conceptual understanding. …

Gesture As A Window To Justification And Proof, Caro C. Williams-Pierce

Mathematics and Statistics Faculty Scholarship

The role of the body, particularly gesture, in supporting mathematical reasoning is an emerging area of research in mathematics education. In the present study, we examine undergraduate students providing a justification for a task about a system of alternating gears, which involves concepts of number relating to even/odd patterns. Some participants were directed to perform gestures relevant to alternation and parity before attempting their justification, while others were not. Although these directed actions did not seem to influence the gestures participants used to solve the problem, we found an important relationship between gesture and mathematical reasoning. In particular, certain types …

Correspondence And Covariation: Quantities Changing Together, Caro C. Williams-Pierce

Mathematics and Statistics Faculty Scholarship

Exponential functions are important topic in school algebra and in higher mathematics, but research on students’ thinking suggests that understanding exponential growth remains an instructional challenge. This paper reports the results of a small-scale teaching experiment with students who explored exponential functions in the context of two continuously covarying quantities, height and time. We present two major conceptual paths that occurred in the development of an understanding of exponential growth, the covariation view and the correspondence view, and discuss the influence of each perspective on the growth of students’ understanding.

Educating Highly‐Qualified Science Teachers, Elizabeth Lewis, Aaron A. Musson, Jia Lu

Discipline-Based Education Research Group Speaker Series

Understanding what makes a highly‐qualified science teacher requires careful research on teacher education programs. Existing research pertaining to secondary science preservice teachers (PSTs) is limited in the areas of: (a) mastery of subject matter knowledge; (b) evolving teaching selfefficacy, and (c) inquiry‐based enacted curricular practices. We studied each issue over the course of an intensive, 14‐month, graduate teacher certification program for practicing scientists and recent science graduates. First, we asked if there was a relationship between amount of content area undergraduate coursework and performance (GPA in core content courses) and found an expected, yet preliminary, connection between higher undergraduate GPA …
