Exploration Of Student Biodiversity Knowledge And Decision-Making For A Wildlife Conservation Socioscientific Issue, Ashley R. Alred
Exploration Of Student Biodiversity Knowledge And Decision-Making For A Wildlife Conservation Socioscientific Issue, Ashley R. Alred
School of Natural Resources: Dissertations, Theses, and Student Research
Global biodiversity, a foundation for ecosystem function, is diminishing at a rate unprecedented in the last 50 years. Biodiversity loss and ecosystem services deterioration is linked to increased food insecurity, reduced water quality and availability, decreased energy security, higher economic losses and human suffering (Millennium Ecosystem Assessment, 2005). Consequently, educators should invest in supporting students in their development of ecological understanding and formal decision-making skills so they are equipped with meaningful tools they can use as scientifically literate citizens. To contribute to that mission, this study seeks to explore student 1) comprehension and explanation of biodiversity concepts and 2) decision-making …
Oral Microbial Burden Of Periodontal Pathogens Among Orthodontic Patients, David Jolley
Oral Microbial Burden Of Periodontal Pathogens Among Orthodontic Patients, David Jolley
UNLV Theses, Dissertations, Professional Papers, and Capstones
Objectives
Many research studies involving orthodontic patients have a natural inclination to focus on changes in levels of cariogenic pathogens after bracket placement, and very few studies examine the role of changes of periodontal pathogens – particularly among adult patients. Interestingly, recent evidence suggests that increased levels of a specific periodontal pathogen, Fusobacterium nucleatum, may elevate risk for development of colon cancer in adults through direct pathways. Based upon this new evidence, the objective of the current study was to screen saliva samples taken from orthodontic patients to determine the prevalence of periodontal pathogens, including F. Nucleatum, T. denticola, and …

Minority Middle And High School Students' Interest In Science: An Exploration Of Teachers' Perceptions, Caroline Makere
Dissertations
A high school teacher conducted a study about minority middle and high school students’ interest in science. The problem was to find out why African American and Hispanic students were showing very little interest in science. The researcher used four middle school science teachers and nine high school science teachers, all from inner city schools in a big city of the Midwest United States except for one middle school teacher from a nearby suburb. The participants answered a survey questionnaire followed with a face-to-face recorded interview. The findings of the study confirmed that students showed little interest in science due …

Guidelines To Avoid Typical Difficulties According To The Rubric For Experimental Design (Red), Annwesa Dasgupta, Nancy Pelaez
PIBERG Publications
Experimental design is an important component of undergraduate biology education as it generates knowledge of biology. Despite its importance, there is limited information about what students actually learn from designing experiments. Dasgupta et al (2014) reported on the development and validation of a Rubric for Experimental Design (RED), informed by a literature review and empirical analysis of thousands of undergraduate biology students’ responses to three published assessments. The RED is a useful probe for five major areas of experimental design abilities: the variable properties of an experimental subject; the manipulated variables; measurement of outcomes; accounting for variability; and the scope …

Effects Of Soil Erosion Barriers On Percent Cover And Sediment Size, Michael Perez
Effects Of Soil Erosion Barriers On Percent Cover And Sediment Size, Michael Perez
STAR Program Research Presentations
Ranching began on Santa Rosa Island in the 1840’s, introducing nonnative megafauna that put selective grazing pressures on endemic species. Dense groves of island oak (Q. tomentella) are aid in sediment deposition and retention. A current restoration effort, involved installing soil erosion barriers, known as wattles, to prevent sediment from being lost upslope and recruit plant growth whose root systems could further stabilize the slope. This experiment was designed to compare percent cover of vegetation growth in areas with and without soil erosion barriers. This was done using the line intercept method (n=42) on three meter transects, measuring …

Evaluating College Biology Laboratory Accommodations For Students With Blindness And Visual Impairments, Barbara Rae Heard
Evaluating College Biology Laboratory Accommodations For Students With Blindness And Visual Impairments, Barbara Rae Heard
All Theses And Dissertations
Studies show that active participation in science laboratory activities promotes student learning. However, students with blindness and visual impairments (BVI) often confront obstacles to active participation in the required activities of the college biology laboratory. Legislation requires institutions of higher education to provide accommodations for students with disabilities, yet the institutions must also maintain the academic integrity of their courses and programs. While college biology instructors provide specific accommodations, such as tactile models and audible devices, to enable active participation by students with BVI, they do so without research-supported guidelines for best practices. This mixed methods study sought to evaluate …

Supplemental Action Learning Workshops: Understanding The Effects Of Independent And Cooperative Workshops On Students’ Knowledge, Kathryn M. Morris
Supplemental Action Learning Workshops: Understanding The Effects Of Independent And Cooperative Workshops On Students’ Knowledge, Kathryn M. Morris
Dissertations
Community colleges enroll more than half of the undergraduate population in the United States, thereby retaining students of varying demographics with extracurricular demands differing from traditional four-year university students. Often in a collegiate lecture course, students are limited in their abilities to absorb and process information presented by their instructors due to content-specific cognitive gaps between the instructor and the student (Preszler, 2009). Research has shown implementation of instructor-facilitated action learning workshops as supplemental instruction may help bridge these cognitive gaps allowing better student conceptualization and dissemination of knowledge (Drake, 2001; Fullilove & Treisman, 1990; Preszler, 2009; Udovick et al., …
Implementation Of Flipped Classrooms In A Non-Major Biology Course, Leah Good
Implementation Of Flipped Classrooms In A Non-Major Biology Course, Leah Good
Scholars Week
With major calls for reform in STEM education from professional organizations (e.g. AAAS, NIH, NSF), studies have found that faculty in higher education can improve student learning by changing their teaching from teacher-centered to student-centered. Change in teaching practice can be difficult, however, especially without significant training. One method of introducing student-centered teaching practices into the classroom is through the use of a flipped classroom model, where students engage in learner-centered activities within the classroom and receive passively-transmitted information outside the classroom. The focus of my study was two-fold, (a) to determine if the flipped classroom method affects student learning …
Why Are Students Doing Research? Examining The Motivation Of Students Involved In Undergraduate Research Programs, Andrew Layne Mcdevitt
Why Are Students Doing Research? Examining The Motivation Of Students Involved In Undergraduate Research Programs, Andrew Layne Mcdevitt
Theses and Dissertations
Use of self-determination theory (SDT) within the science classroom focuses primarily on ways to integrate intrinsic motivation into students' identity. Experiential learning plays a large role in promoting learning by shaping students' interests, identity, and intrinsic aspirations. This phenomenological research study sought to understand how experiential learning experiences helped influence career aspirations of graduate students within ecological disciplines. By determining how their experiences met three basic psychological needs outlined by SDT (competence, autonomy, and relatedness), we were able to examine which regulators drove motivation.
In the qualitative pilot study, participants developed a genuine enjoyment and appreciation for their discipline as …

Assessing Student Comprehension In Introductory Biology: A Comparison Of Free-Response And Multiple-True/False Exam Formats, Macy A. Potts, Brian Couch, Joanna K. Hubbard
UCARE Research Products
Question format is an important consideration when designing instruments to gauge student comprehension. In many lecture-style courses, instructors must decide how to effectively test a large group of students. Two common types of question formats used for introductory biology exams are free-response (FR) and multiple-true/false (MTF). FR questions include a question prompt which students respond to with essay-style answers. Conversely, MTF questions include an opening question stem with accompanying statements to be marked as either true or false. The goal of this study was to determine the advantages and disadvantages of FR and MTF question formats for assessing student comprehension …
Assessing The Impact Of Historical Story Telling On Student Learning Of Natural Selection, Janice Marie Fulford
Assessing The Impact Of Historical Story Telling On Student Learning Of Natural Selection, Janice Marie Fulford
Dissertations
Research suggests that because of its historical nature, the learning of evolutionary biology is problematic compared to that of other science disciplines. While explanations used in historical sciences often employ historical narratives, which are distinct from narratives in other contexts, such as stories, the two types of narratives have structural similarities that suggest the potential role of stories based in the history of science for the teaching of evolutionary biology. Stephen Klassen, a prominent science educator, has studied how stories from the history of physics can promote the learning of and attitudes towards science. Klassen’s pioneering work identifies structural components …

The Unites States, while being one of the richest countries in the world, ranks 17th in science proficiency out of 31 countries. New techniques for teaching are needed if the US wants to keep up with increasing global competition. Often the problem with traditional methods for teaching biological processes is that they present the material as linear or causal, when in fact there is a much wider network at play. For example, cellular respiration is often represented as a linear process that always starts with glucose and always ends with ATP and water. However, there are several entry and exit …

The Engaged Microbiologist: Bringing The Microbiological Sciences To The K-12 Community, David J. Westenberg
Biological Sciences Faculty Research & Creative Works
Exposing K-12 students to cutting edge science that impacts their daily lives can bring classroom lessons to life. Citizen-science projects are an excellent way to bring high-level science to the classroom and help satisfy one of the cornerstone concepts of the Next Generation Science Standards (NGSS), "engaging in practices that scientists and engineers actually use." This can be a daunting task for teachers who may lack the background or resources to integrate these projects into the classroom. This is where scientific societies such as the American Society for Microbiology (ASM) can play a critical role. ASM encourages its members to …

Parts Of The Whole: Teaching Quantitative Reasoning In The Predator-Prey Model, Dorothy Wallace
Numeracy
The classical predator-prey equations are in nearly every differential equations text and mathematical biology text. Usually they are presented fait accompli, leaving the student to analyze them or play with a computer program. Here we show that the process of fully understanding where these equations come from and how they are derived provides numerous opportunities to teach or reinforce quantitative reasoning skills necessary to future scientists. This example is used to invoke logic, systems thinking, causal reasoning, understanding functions of one or more variables, quantities versus rates of change, proportional reasoning, unit analysis, and comparison to data.
