This corpus-based, qualitative descriptive study examines the vocabulary in digital science resources for middle school students in the United States. In brief, two corpora, each of approximately 2.7 million tokens, were assembled: the Digital Science Corpus (DSC) and the Digital Fiction Corpus (DFC). The 3,456 digital science resources included in the DSC were selected based on the findings of a detailed survey of 91 U.S.-based middle school teachers. In this study, AntWordProfile (Anthony, 2021), AntConc (Anthony, 2019), and WordSmith Tools (Scott, 2020) were used to (a) lexically profile the corpus to determine the vocabulary load of vocabulary in the corpus, (b) lexically profile the corpus to estimate the extent to which a combination of well-known word lists (GSL+AWL+ EAP Science List, the top 570 AVL word families, GSL+MSVL for Science) might help students to reach text coverage that could result in reasonable comprehension of the texts in the corpus (i.e., lexical coverage), and (c) create a Digital Science List (DSL) that captures the most frequent words types in the corpus. The word types in the DSL were validated with the Digital Fiction Corpus (DFC), a corpus formed from an approximately equal number of tokens as the DSC but gathered from fiction novels. The findings of this study show that the top 570 word families in the AVL (Gardner & Davies, 2014) provide 75% more lexical coverage in the digital corpus than the 570 word families in the older AWL (Coxhead, 2000) (10.07% vs. 5.76%). To reach a threshold of 95% coverage that is conventionally deemed to facilitate minimal reading comprehension (Laufer, 2020), middle school (MS) students must recognize the first 6,000 most frequent BNC/COCA (Nation, 2012) word families plus proper nouns or the first 11,000 most frequent BNC/COCA word families without proper nouns. Furthermore, to reach 98% coverage for optimal reading comprehension of digital science texts requires recognizing words within the 19,000 most frequent word families in the BNC/COCA plus proper nouns. In contrast, the GSL, AWL, and EAP Science List with far fewer word families ( < 3,000) offer a striking 88.35% lexical coverage across the corpus, while the GSL and the MSVL for Science with fewer than 2,500 word families offer a remarkable 87.79% lexical coverage across the corpus. The DSL produced from this research identified 412 types based on seven corpus-based and judgment-based criteria. The lexical profiling analysis of the DSL across the DSC revealed that the DSL provides 8.64% lexical coverage. While the DSL can be used as a teaching and learning tool in middle school classrooms, this list is specifically helpful for second language (L2) because it contains 136 general high-frequency types with a specialized meaning (e.g., dating, work, etc.). The study addresses methodological, theoretical, and pedagogical implications so that middle school learners can gain better support in their science vocabulary development and achieve better science reading comprehension of digital science texts.

This qualitative, ethnographically informed case-study examines how social, psychological, and organizational factors of a culture impact writing instruction and practice within an English Language Arts middle school class. In order to explore possible reasons for stagnant writing instruction in middle schools, two research questions guided this study: (RQ1) What do the components of writing instruction look like in one middle school class?, and (RQ2) How does one middle school ELA class exhibit identity distinction, writing development, and discourse surrounding writing instruction? I examined how one middle school class exhibits identity distinction among students and teachers within writing, development of writing, and discourse surrounding writing instruction and practice. Data were collected through observations, field notes, interviews, and cultural artifacts (i.e., lesson plans, student data, student work samples, and district curriculum) over a five week period for a total of 18 data collection days (16 of which were observations). Observations were conducted in one seventh grade teacher's class period and lesson planning meetings. The seventh grade teacher, students, and Testing Coordinator were interviewed for member checking sessions pertaining to observations and student work. Semi-structured interview verbatim transcripts were audio recorded and transcribed, after which the following themes emerged: understanding of writing instruction, understanding of writing workshop, confidence in students' writing abilities, establishing spaces for student engagement, feedback on student writing, and teacher and student identities. Also included are recommendations for establishing a positive writing culture through improved middle school writing instruction.

The purpose of this study was to investigate how the lived experiences and views of fourth- and fifth-grade math teachers who implemented project-based learning (PBL) addressed the needs of their at-risk students in urban schools. The researcher examined the use of PBL in mathematics-impacted instruction, seeking to understand teacher beliefs related to the influence of exposure to PBL experiences on students' academic outcomes. When deliberately planned and embedded into teaching, the implementation of PBL helps students retain content, improve attitudes about learning, and improve their ability to collaborate with others (Cervantes et al., 2015). A literature review was conducted to explore PBL and its relationship with constructivism, growth mindset, and cooperative learning and the degree to which these teaching methods affect student learning. A growth mindset enables students to consider inquiry, exploration, and student collaboration (Larmer et al., 2015). Also present in PBL are cooperative learning activities, which Slavin (2015) found encouraged students to work together on projects that required the inclusion and student application of content standards. Qualitative research methodology using the phenomenological method was implemented in this study. The study investigated the lived experiences of fourth and fifth-grade math teachers who implemented PBL in urban schools. The researcher interviewed teachers who have participated in project-based learning with their students. Results and discussion are included for the research question as well as implications of the findings, recommendations, and suggestions for future research.

High-quality and effective professional development is necessary and "…should be made available to all teachers" (Borko, 2004, p. 3). This dissertation focuses on teacher professional development (PD) and an exploration into the meaning teachers attribute to a PD experience. Stemming from interdisciplinary questions such as, how do we align PD to meet teachers' needs and expectations? and how do teachers learn?, this study aims to examine the experiences and meanings of specific sixth grade ELA teachers in their participation in District PD, a district-led PD series using Interpretative Phenomenological Analysis (IPA). IPA stems from qualitative and ontology research perspectives and captures the context of human experience, phenomena, and life. After thorough analysis of each participant interview transcript and reflection, the results of this dissertation shed light about the reality of the District PD experience for each of the three participants. Moreover, these findings indicated five themes: Teacher Embodiment, the District PD Experience, the Meaning of PD, the Success and Value of District PD, and Unexpected Findings. These themes demonstrated the need for teachers to be heard, their epistemological beliefs to be acknowledged, their meanings of a PD experience, and the design of PD that enhances task value, expectancies for success, and cost across all PD experiences. Results suggested the flexibility of IPA and its application to current PD practices of teachers' experiences and meaning. Implications and recommendations such as, a prescreening survey given to future participants would aid the development of an aligned PD for teacher participations and collecting data across all four sessions of District PD would better inform this phenomenon. Further research into teacher PD and IPA across other disciplines are also presented and discussed. These include researching participatory research approaches, a longitudinal study of District PD over a course of two years, and the intersectionality of teacher PD, Interpretative Phenomenological Analysis, and Expectancy Value Theory (EVT).

The objective of the study was to research the impact 21st Century Community Learning Centers (CCLC) has on Title 1 middle school students in Seminole County. A mixed methods design was used to interview and survey teachers working for the after-school program, and student data was collected to assist in identifying the impact of the program. Initially, interviews were conducted to research the implementation of the program. Following interviews, willing participants completed the survey sent out to all middle school teachers who work for 21st CCLC. The survey investigated how the vision of the program was presented to staff and students. Data was then collected from middle school students attending the program from 2015 to 2017. The data collected was used to research whether there was a correlation between students' attending the after-school program and their Florida State Assessment (FSA) scores as well as their grade point average (GPA) in school. Qualitative data was collected and coded from teachers. There was a variance between each site on the implementation and vision of the after-school program as stated by the grant. Student data displayed that there was no correlation between students' attending the program and FSA scores. There was a correlation between students' GPA and their attendance at the after-school tutoring program. Further investigation is necessary to research larger sample sizes outside of Seminole County.

Teachers are asked every day to teach a variety of subjects to their students, but it is often challenging to find enough time in the day to teach every subject. Often, social studies is the subject that gets left out of the curriculum. The purpose of this project was to examine the research behind thematic units and determine their role as a strategy to teaching social studies in the intermediate grades classroom. I researched thematic units including how to create them and their benefits and challenges. Using the research, I then made a resource for teachers to create their own thematic unit. This resource includes the steps to use to create a unit and how to find quality children’s literature to use in the unit. It also includes how to plan the unit and examine the standards then brainstorm ideas for lessons in the unit. Titles of children’s literature that relate to the thematic unit are included. The resource also includes a sample social studies thematic unit that teachers can use as a guide to create their own units.

The primary goal of this mixed method study is to investigate and analyze how the nature and structure of the widely accepted middle school and teaming models impact individual teacher efficacy as well as collective efficacy. I examined the implications of these models on the levels of efficacy for both teamed and non-teamed teachers. Both social cognitive theory and belonging theory informed the research study. The mixed method study was conducted at seven suburban middle schools in four districts outside of a major city in the northeastern section of the country. Each middle school utilizes the teaming model as the focal point of their philosophy. Research data were gathered from volunteer teachers through the administration of an online 37-item survey and voluntary individual follow-up interviews. In addition, principal interviews served to give background and cultural information at the building level. Themes from survey data informed the interview protocol. A review of historical documents provided additional information. The data were analyzed and themes were extracted in order to provide recommendations for these particular middle schools. Based on the collected data, teachers working at the middle school level can experience varying levels of both individual teacher and collective efficacy based on teaching position and experience. Implications for further research in the area of teacher and collective efficacy at the middle school level are noted. / Educational Administration

The purpose of the study is to determine what selected school districts throughout the state of Texas are doing to meet the Texas Gifted and Talented mandate at the high school level, grades 9-12. The study is also to help determine if more guidelines from the state are needed, or if schools are able to meet student needs and mandate requirements as they currently exist.
