Concepts In Animal Parasitology, Chapter 69: A Short Introduction To Marine Parasitology: Marine Parasites Of Economic And Medical Importance [Auxiliary Concepts], Klaus Rohde, Robin M. Overstreet

Concepts in Animal Parasitology

Chapter 69 in Concepts in Animal Parasitology, S. L. Gardner and S. A. Gardner, editors. 2024. Zea Books, Lincoln, Nebraska, United States

Introduction

Parasitism, in this chapter, is defined as “a close association of two organisms, in which one—the parasite—depends on the other—the host—deriving some benefit from it. The benefit is often food” (Rohde, 2005b). Many bacteria, viruses, and fungi are parasitic but usually not studied by parasitologists sensu stricto; they are the domain of microbiologists. Parasites as defined here do not always harm their host; the border between so-called genuine parasites and other symbionts such as commensals is often …

An Analysis Of The Essential Understandings In Elementary Geometry And A Comparison To The Common Core Standards With Teaching Implications, Helen Crompton, Sarah Ferguson

STEMPS Faculty Publications

Geometry and spatial reasoning form the foundations of learning in mathematics. However, geometry is a subject often ignored by curriculum writers and teachers until high school, leading to students lacking in critical skills in geometric reasoning. As the United States moves into a new curriculum epoch, heralding the commencement of the national common core standards (CCS), one could question if CCS in geometry align with the essential understandings children need to be successful geometric thinkers. This paper begins with an examination of the essential understandings of geometric reasoning leading to an interpretation and critique of the elementary geometry CCS. Finally, …

Investigating Division Quest: A Text-Based Adventure Narrative Game For Overcoming Difficulties Of Mitosis Learning, Amanda G. Conner

College of Graduate Studies: Theses & Dissertations

Mitosis learning is a source of struggle for many introductory biology students. Much of this difficulty stems from an overwhelming amount of terminology and moving pieces as well as the abstract nature of cellular processes. Game-based learning (GBL) has been used in other contexts to reduce cognitive load and provide relatable experiences upon which students can construct their mental models. However, commercial GBL is often expensive and difficult to align with individual instructor teaching preferences and learning objectives. In this study, we use a mixed methods approach to explore the use of a GBL tool made in Twine to overcome …

A Project-Based Learning Activity For An Engineering Technology Heat Transfer Course To Design A Shell-And-Tube Heat Exchanger, Nathan Luetke, Orlando Ayala

Engineering Technology Faculty Publications

Thermofluids courses demand a strong grasp of mathematics and employ physics extensively to describe physical systems. Heat transfer, in particular, presents challenging topics, which can be even more daunting for engineering technology students. In this paper, we present the implementation of a project-based learning activity in the engineering technology heat transfer course. The students' task involves designing a shell-and-tube heat exchanger to meet specific minimum requirements. The objective is to provide students with a real-world assignment that enhances their heat transfer calculation skills. To accommodate instructors' busy schedules, we have developed an assignment that is user friendly. Detailed instructor guides …

3ddp Engineering Design Intervention Impacts On Student Perceptions, Attitudes, And Interest Towards Engineering, James Robert Kane

Theses and Dissertations

The study, “3DDP Engineering Design Intervention Impacts on Student Perceptions, Attitudes, and Interest Towards Engineering” explored the impact of a culturally responsive, semi-formal 3D printing (3DDP) intervention on middle school students' perceptions, attitudes, and interest in engineering. The intervention aimed to broaden access to engineering education by providing formative experiences outside traditional classroom settings within the regular school day. A multifaceted approach was employed, utilizing quantitative analysis of assessments and surveys, qualitative analysis of written responses, follow-up interviews, and student-produced artifacts. The intervention functioned as a student-driven engineering club, integrating culturally relevant themes and hands-on activities spanning diverse engineering domains. …

Combining The Concrete Representational Abstract Framework And Video Modeling To Increase Basic Addition Skills Among First Grade Students, Sara Ebner

Theses and Dissertations--Educational, School, and Counseling Psychology

Proficiency in mathematics is fundamental for academic success and is linked to numerous skills that are essential for success in the real-world. Despite its importance, many students struggle with math, leading to nationwide declines in math proficiency. This decline highlights the need for effective interventions that are accessible, able to be individualized, and feasible for implementation across settings. In the present study, a single case multiple probe across participants design was used to assess the efficacy of a concrete-representational-abstract (CRA) framework with video modeling intervention on the basic addition problem-solving accuracy of three first-grade students. Results show that participants’ accuracy …
