Mach: A Model For Explaining Molecular And Cellular Mechanisms, Caleb M. Trujillo

Open Access Dissertations

Biologists use mechanistic explanations to understand behaviors of the immense complexity of molecular and cellular systems. In undergraduate biology courses, students are expected to explain molecular and cellular mechanisms, but teaching this skill presents many challenges due to the highly abstract, intangible nature of the cellular world, the influence of everyday language, and the tendency of students to overestimate how much they can explain. Therefore, across three studies this dissertation addresses these obstacles to teach undergraduate biology students to explain molecular and cellular mechanisms. ^ The first step was to model how biology experts explain molecular and cellular mechanisms, and …

Effects Of Successmakers Math As An Intervention For Students, Jennifer Lee Calcut

Walden Dissertations and Doctoral Studies

Schools throughout the United States use the IQ-achievement discrepancy method to

identify children with learning disabilities. This current method allows many students to fall behind in the regular education setting. In 2004, the Individuals with Disabilities Education Act was reauthorized to provide states with the option of using a response to intervention (RtI) model in lieu of or in conjunction with the IQ-achievement discrepancy model. The purpose of this quasi-experimental, single subject, pre/posttest design study was to determine the impact of a Tier II intervention using SuccesMakers Math, a learning system that adapts to the unique needs of the individual …

Motivation And Learning Of Non-Traditional Computing Education Students In A Web-Based Combined Laboratory, Michael Jesse Green

CCAC Theses and Dissertations

Hands-on experiential learning activities are an important component of computing education disciplines. Laboratory environments provide learner access to real world equipment for completing experiments. Local campus facilities are commonly used to host laboratory classes. While campus facilities afford hands-on experience with real equipment high maintenance costs, restricted access, and limited flexibility diminish laboratory effectiveness. Web-based simulation and remote laboratory formats have emerged as low cost options, which allow open access and learner control. Simulation lacks fidelity and remote laboratories are considered too complex for novice learners.

A web-based combined laboratory format incorporates the benefits of each format while mitigating the …

Math In The Dark: Tools For Expressing Mathematical Content By Visually Impaired Students, Patricia M. Mcdermott-Wells

CCAC Theses and Dissertations

Blind and visually impaired students are under-represented in the science, technology, engineering, and mathematics disciplines of higher education and the workforce. This is due primarily to the difficulties they encounter in trying to succeed in mathematics courses. While there are sufficient tools available to create Braille content, including the special Nemeth Braille used in the U.S. for mathematics constructs, there are very few tools to allow a blind or visually impaired student to create his/her own mathematical content in a manner that sighted individuals can use. The software tools that are available are isolated, do not interface well with other …

Community Chairs As A Catalyst For Campus Collaboration In Stem, Neal Grandgenett, David Boocker, Hesham Ali, Angela M. Hodge, Brian Dorn, Christine E. Cutucache

Biology Faculty Publications

Strong collaborative partnerships are critical to the ongoing success of any urban or metropolitan university in its efforts to build the science, technology, engineering, and mathematics (STEM) career pathways so critical to our nation. At the University of Nebraska at Omaha, we have established a faculty leadership structure of "community chairs" that work across colleges to support campus priorities. This paper describes UNO’s STEM community chair model, including selected initiatives, impacts, and challenges to date.

Special Speciation, Lyn L. Countryman, Jill D. Maroo

Faculty Publications

Considerable anecdotal evidence indicates that some of the most difficult concepts that both high school and undergraduate elementary-education students struggle with are those surrounding evolutionary principles, especially speciation. It’s no wonder that entry-level biology students are confused, when biologists have multiple definitions of “species.” We developed this speciation activity to provide clarity and allow students a hands-on experience with a speciation model.

-- Do you wish your students would show and …

Building Cloud-Based Information Systems Lab Architecture: Deriving Design Principles That Facilitate The Effective Construction And Evaluation Of A Cloud-Based Lab Environment, Thomas J. Trevethan

CCAC Theses and Dissertations

The problem explored in this dissertation report was that at the time of this study, there were no design principles or methodologies based on design science research (DSR) available to use for artifact construction, implementation, and effective evaluation of cloud-based networking lab environments that can be used to foster hands-on technology skills in students. Primarily based on Hevner’s 7 guidelines of DSR, Peffer’s design science research methodology (DSRM), and Gregor’s IS design theory, this study forms the groundwork for the development of procedures and specifications derived from DSR literature to facilitate the construction, implementation, and evaluation of a comprehensive cloud-based …

A Study Of The Emergence Of Student Tacit Knowledge In Response To Environmental Images And Science Instruction, Rory J. Glass

Legacy Theses & Dissertations (2009 - 2024)

The purpose of this study was to identify the presence of students’ tacit understandings as they apply to environmental science content, and to discover how these understandings emerge and are viewed and interpreted by teachers. Towards that end over ten hours of classroom video was recorded and analyzed, from both large urban and smaller urban classrooms. Additionally, interviews were conducted with 15 students and two teachers to gain insight into their thinking on an array of topics related to the environment and environmental reasoning. It was hypothesized that students’ understandings and teachers’ interpretations of them may be influenced by their …

Women's Decision To Major In Stem Fields, Stephanie Conklin

Legacy Theses & Dissertations (2009 - 2024)

This paper explores the lived experiences of high school female students who choose to enter into STEM fields, and describes the influencing factors which steered these women towards majors in computer science, engineering and biology. Utilizing phenomenological methodology, this study seeks to understand the essence of women’s decisions to enter into STEM fields and further describe how the decision-making process varies for women in high female enrollment fields, like biology, as compared with low enrollment fields like, computer science and engineering. Using Bloom's 3-Stage Theory, this study analyzes how relationships, experiences and barriers influenced women towards, and possibly away, from …

Learning Biology Through Innovative Curricula: A Comparison Of Game- And Nongame-Based Approaches, Troy D. Sadler, William L. Romine, Deepika Menon, Richard E. Ferdig, Leonard Annetta

Department of Teaching, Learning, and Teacher Education: Faculty Publications

This study explored student learning in the context of innovative biotechnology curricula and the effects of gaming as a central element of the learning experience. The quasi-experimentally designed study compared learning outcomes between two curricular approaches: one built around a computer-based game and the other built around a narrative case. The research questions addressed student learning of basic biological principles, development of interest in learning science, and how a game-based approach compared to a nongame-based approach in terms of supporting learning. The study employed a pre-post design with 1,888 high school students nested within the classes of 36 biology teachers. …

Do Teacher Judgment Accuracy And Teacher Feedback Predict Student Achievement In Elementary And Middle-School Science?, Mason Albert Kuhn

Dissertations and Theses @ UNI

The quest to find the most effective approach to teach science has challenged teachers and scholars for decades (Ford, 2012; Kuhn, 2010a; Duschl, Schweingruber, & Shouse, 2007). Unfortunately, the recent push for quality science education in schools has not yet resulted in higher achievement on standardized science assessments in the United States. The increased focus on science in school and the lack of growth on national and international standardized assessment has led to reformed-based policies, such as the Next Generation Science Standards (NGSS), that ask teachers to teach in a way that emulates the practices of scientific inquiry, including argument-based …

The Leadership Efficacy Of Graduates Of North Carolina School Of Science And Mathematics: A Mixed-Methods Analysis, Renee Mason Letita

Dissertations

This study examines the leadership efficacy amongst graduates of NCSSM from the classes of 2000–07 as the unit of analysis. How do NCSSM graduates’ perceptions of their leadership efficacy align with research on non-cognitive variables as indicators of academic performance using the unit of analysis as a performance outcome? This study is based on the theoretical construct that non-cognitive psychological (also called motivational) factors are core components of leadership self-efficacy, indicative of NCSSM graduates (who had high academic performance and attained STEM degrees). It holds promise for increasing both student interest and diversity in the race to strengthen the STEM …
