Description
In today's world, critical thinking and using a systems approach to problem solving are skills that are far too rare. In the age of information, the truth has become muddled by "fake news" and a constant barrage of exaggerations or blatant falsehoods. Without critical thinking skills, "many members of our society do not command the scientific literacy necessary to address important societal issues and concerns" (NCES 2012, p.11). Additionally, far too many people are incapable of thinking long term and understanding how their actions affect others. Because of this shortsightedness our world is facing one of its biggest ecological crises \u2014 global warming confounded by overpopulation and overconsumption. Now, more than ever, it is critical "for our young people to have a basic understanding of the relevant scientific ideas, technologies and ethical issues and powers of reasoning, to be prepared to face these issues" (Harlen et al., 2015). I believe that investigating innovative ways to teach ecology could be an important step to accomplishing this. Learning to think like a scientist forces people to rely on facts, follow similar protocols to deduce these facts, and be able to think critically about misleading events. More specifically, ecology education will allow people to develop those skills while also learning about team work, open-mindedness, and their environment. Ecology is defined as "the branch of biology that deals with the relations of organisms to one another and to their physical surroundings" (Dictionary.com, 2018). It is clear that this subcategory of science could act as a powerful introduction to the scientific world and how we relate to it. Its introduction at a young age has the potential to create a generation of conscientious and curious lifelong learners. In an attempt to support effective ways to teach ecology, I developed an educational unit and applied it in different educational contexts. My target audience was elementary aged students and I tested this unit with children in Phoenix Metropolitan Area afterschool programs. I taught core concepts of ecology \u2014 the water cycle, the sun's energy, plants and photosynthesis, and food webs \u2014in a sequence of lesson plans that build upon each other. Finally, I determined the appropriate age group and setting for these lesson plans through research and in-class observations. In this document, I explain the process I went through in developing my lesson plans, why I felt compelled to make them, and my experiences in implementing them.

In the Spring of 2021, I had an internship with Butterfly Wonderland, where I worked in their conservatory and learned about the ecological relationship between butterflies and plants. As part of my internship, I encouraged guests to learn more about gardening for pollinators. That experience inspired me to complete a creative project in which I would design a butterfly garden of my own that would highlight wildlife benefits and be accessible to people like myself, who do not have their own gardens and don’t have hundreds of dollars to spend on gardening supplies.
In collaboration with Dr. Gwen Iacona and Liz Makings (director and second committee member respectively), I planted accessible gardens. By “accessible”, I mean that the gardens were affordable (less than $100 total), included free/upcycled materials wherever possible, and are easily replicable. For my project, I made ‘prototypes’ of the gardens by using freely available seeds and soil sources, germinating those seeds in the ASU Greenhouses, and documenting my process so that it could be shared. Freely available seeds and other materials came from a variety of places including the ASU seed library, local Free Little Libraries, donations, as well as purchases from on campus fundraisers. The germination and growth of seeds in the ASU greenhouse took place over the course of several months in the fall and winter. That documentation has taken on several forms, including an informational pamphlet about wildlife gardening and flyers specific to locally available plant seeds. I find this to be very important because my end goal was to create something that other students or people in our community can use in a practical way. I wanted to create something that will bring gardening into the homes of people who didn’t think they were able to participate in it.

Description
Despite the increasing number of elementary and secondary school students with language and learning disabilities and federal laws mandating ongoing collaboration among diverse school professionals, the implementation and maintenance of Interprofessional Collaborative Practices (ICP) and classroom-based therapy services among teachers and speech-language pathologists (SLPs) is low. Teachers and SLPs need training to implement and maintain ICP and classroom-based therapy services. An interprofessional community of practice (ICoP) framework was developed to operationalize ICP competencies into measurable knowledge, skills, attitudes, and practice behaviors. These were incorporated into designing, implementing, and assessing the ICoP framework’s activities and outputs. Thus, the purpose of this mixed methods action research study was to examine the impact of the ICoP framework on teacher and SLP participants’ knowledge and self-efficacy of ICP competencies. The study also sought to build participants’ capacity to implement and maintain classroom-based therapy services for students with language and literacy impairments in an inclusive classroom setting. Participants included four general education teachers, five special education teachers, and three SLPs in a K-8 public school district in the southwest region of Arizona. Inferential statistics and thematic analysis were used to analyze participants’ responses to surveys, semi-structured interviews, and logbook entries before and after the eight-week innovation. Results from the data analysis showed that teachers and SLPs demonstrated a significant increase in knowledge and self-efficacy of ICP.

Description
Given the increasing number of students with dis/abilities entering higher education institutions (HEI), it is imperative higher education faculty have the knowledge, skills, and disposition to effectively support students with dis/abilities. Therefore, this study engaged higher education faculty at Mary Lou Fulton Teachers College (MLFTC) at Arizona State University (ASU). ASU is an institution that prides itself on being inclusive. Accordingly, MLFTC enrolls many students with a dis/ability. In spring of 2022, more than 350 MLFTC students had disclosed their dis/ability and registered for accommodations. However, there were likely many more students attending MLFTC who had chosen not to disclose their dis/ability status. Consequently, faculty members need a proactive approach to meeting the needs of students with a wide range of knowledge, skills, and experiences including students with dis/abilities.Universal Design for Learning (UDL) offers an effective framework to proactively support students with dis/abilities, even if they choose not to disclose their dis/ability status. Faculty need professional development and collaboration opportunities to develop to integrate inclusive instructional strategies aligned to UDL. This study was designed to provide higher education faculty members opportunities to develop their skills to integrate UDL in their classrooms. The participants completed three asynchronous online modules about the principles of UDL and three Innovation Configuration (IC) map design sessions. During the IC map design sessions, they co-developed an IC map articulating how they would like to see UDL operationalized in their courses. Data was collected throughout the project through a pre/post inventory, transcripts of the IC map design sessions, interviews, a classroom observation, and the co-developed IC map. The results show that faculty collaboration likely has a positive impact on faculty integrating instructional strategies aligned to UDL. However, collaboration may have a limited impact on the underlying belief system faculty have about the use of inclusive practices, especially for students who do not have a dis/ability or have chosen not to disclose their dis/ability through official university channels.

Description
For decades, there has been a concerted effort to support the transition of first-generation students from high school into higher education, yet there is a continued troubling gap in the number of first-generation students attending college who attain success once enrolled. This disparity is particularly pronounced among low-income students of color. This study illustrates how action research can be used to analyze a program that aims to assist students and their parents in navigating the American higher education system. Participants included (N=20) twelfth grade, first-generation, Latino, students and their parents (N=20) in rural Yuma County, Arizona, a geographically isolated area which is a three-hour drive from the nearest metropolitan city. Mixed methods were utilized to examine the impact of the American Dream Academy on self-efficacy in cultivating a college-going culture among first-generation, Latino students. Since parents play a significant role in the academic success of students, this program also sought to bolster the self-efficacy of the parents of the twelfth-grade student participants. A concerted effort was made to bring the American Dream Academy to the San Luis High School, Arizona Western College, and Arizona State University. The Academy’s curriculum included eight sessions that covered college-going topics that were collectively facilitated by university, college and high school faculty. Outcomes of this study indicate the need to support first-generation Latino students and their parents to foster college readiness and increase college access. Additionally, this study highlights how increasing the self-efficacy of students and parents can positively shift self-perceptions and sense of belonging among first-generation college students.

The Model Classroom Initiative (MCI) was conceptualized to improve learning and IEP goal attainment while decreasing maladaptive behaviors in specialized instructional program classrooms. The MCI Coaching Model was utilized to assist teachers with the implementation of MCI components in three specialized instructional program classrooms, all of which served students with autism and developmental delays. Data were collected using Innovations Configuration Maps, observations, coaching, surveys, classroom data, and interviews and were analyzed using a mixed methods approach. Results indicate that the MCI coaching sessions increased participant teachers’ feelings of support and being heard and slightly decreased stress, increased the implementation of the chosen components for two of the three teachers, increased the knowledge of and confidence in the MCI components, and increased the teachers’ perception that the coaching helped to increase the students’ academic, behavioral, and Individual Education Plan (IEP) goal progress.

Description
The need for new tuberculocidal drugs is crucial with drug resistance on the rise as the tuberculosis epidemic rages on. One new potential drug target is the PrrAB two component system (TCS) since it does not exist in humans and is essential to viability in Mycobacterium tuberculosis. This project examines Mycobacterium smegmatis, and this nonpathogenic and fast-growing organism possesses two full length PrrAB orthologs, in addition to an orphaned PrrB sensor histidine kinase. While it was determined that PrrAB1 and PrrAB2 are nonessential, the lone PrrB3 is not yet characterized for essentiality. To confirm individual dispensability of PrrAB1 and PrrAB2 and investigate the essentiality of PrrB3 and the full M. smegmatis PrrAB multiplex, we utilized CRISPRi dCas9 to repress the expression (knockdown) of prrAB1 (MSMEG_5662-5663), prrAB2 (MSMEG_0244-0246), and the lone prrB3 (MSMEG_2793) in M. smegmatis independently and simultaneously. Repression of prrAB1 resulted in the greatest growth defect, with a lag of 17 cellular division cycles compared to the control, a strain generated with an empty vector. However, the knockdown of prrAB1 was not lethal to M. smegmatis. The inhibition of all three prrAB orthologs simultaneously, also known as a multiplex knockdown, lagged the control by 13 cellular division cycles. At the 48-hour point, both the single ortholog repression of prrAB1 as well as the whole prrAB system knockdown had a growth defect of 13 replication cycles behind the control. However, the multiplex knockdown stabilized growth at 48 hours, revealing a possible compensatory mechanism in M. smegmatis. Conclusively, we show that the PrrAB TCS is globally inessential for viability in M. smegmatis.

Description
Wound healing is a complex tissue response that requires a coordinated interplay of multiple cells in orchestrated biological processes to restore the skin's barrier function post-injury. Proteolytic enzymes, in particular matrix metalloproteinases (MMPs), contribute to all phases of the healing process by regulating immune cell influx, clearing out the extracellular matrix (ECM), and remodeling scar tissue. As a result of these various functions in the healing of skin wounds, uncontrolled activities of MMPs are associated with impaired wound healing. The MMP gene family consists of a highly conserved set of genes. Deleterious mutations in MMP genes cause developmental phenotypes that affect the heart, skeleton, and immune system response.
The availability of contiguous draft genomes of non-model organisms enables the study of gene families through analysis of synteny and sequence identity. My project is aimed at conducting a comparative genomic analysis of the MMP gene family from the genomes of 29 tetrapod species—with an emphasis on reptiles. Results regarding the similarities and differences among MMP protein sequences can be further investigated to shed light on the causes which give rise to various adaptive mutations for specific species groups.

Description
Visual presentation of information is one method of learning that has the ability to enhance STEM learning compared to learning solely through text. Educational psychology research is ongoing in the STEM field for how students can learn better through visual representations in their course material. The goal of this study was to assess student responses to visual mini-lessons related to course content in the cardiovascular unit in Animal Physiology (BIO360) at Arizona State University. Study participants completed a series of eight mini-lessons and a survey on their experience with the visual lessons. The results of the survey identify increased desire for visual learning materials in STEM courses. The study participants reported that they felt more visual aids in their STEM courses would increase their understanding of course content and that their classroom performance would improve.

The incidence of childhood obesity has become increasingly prevalent in the United States in recent years. The development of obesity at any age, but especially in adolescence, can have lasting negative effects in the form of cardiometabolic disease, increased incurred healthcare costs, and potential negative effects on quality of life. In recent years, a rising trend of obesity, in both adults and adolescents, has been observed in lower income and ethnic groups. Increased adiposity can be influenced by modifiable factors -(physical activity, caloric intake, or sleep) or by non-modifiable factors (ethnicity, genetic predispositions, and socioeconomic status). The influence of these factors can be observed in individuals of all ages, including infants. A common indicator of the development of childhood obesity is rapid weight gain (RWG) within an infant’s first year of life. The composition of the gut microbiome can act as a predictor for RWG and the development of childhood obesity. Infants are exposed to an immense microbial load when they are born and their gut microbiome is continually diversified through their method of feeding and the subsequent introduction to solid foods. While currently understudied, it is understood that cultural and socioeconomic factors influence the development of the gut microbiome, which is further explored in this analysis. The DNA from 51 fecal samples from infants ranging from 3 weeks to 12 months in age was extracted and sequenced using next-generation sequencing, and the resulting sequences were analyzed using QIIME 2. Results from alpha-diversity and beta-diversity metrics showed significant differences in the gut microbiome of infants when comparing groups based on baby race/ethnicity, household income, and mom’s education. These findings suggest the importance of sociodemographic characteristics in shaping the gut microbiome and suggest the importance of future studies including diverse populations in gut microbiome work.
