<p>Vocabulary and communication are essential components of mathematics that should be addressed in the classroom. Knowledge of mathematical vocabulary has been argued as a necessary building block for students to engage in purposeful discourse. However, previous studies primarily focus on vocabulary instruction strategies specifically for English Language Learners and early childhood students. Discourse in mathematics education continues to be a major theme in national standards publications. Both empirical and theoretical studies have shown that discourse allows students to build conceptual knowledge by participating in purposeful conversations. Further, previous research has found that learners are given the opportunity to increase their own ability when using social interactions as a gateway to develop higher mental functions that aid in transitioning from thought to word and visa versa. Since mathematics curricula are often influenced and developed using national standards documents as foundational resources, it is important to explore the types of vocabulary and the levels of discourse that are currently being used in the classroom. This study considers the cases of four mathematics teachers to focus on what types of vocabulary are used and what levels of discourse are evident in high school mathematics classrooms. Data sources included video-recorded observations and classroom artifacts including teacher-created materials and the district-provided curriculum. Qualitative analysis techniques were used in this study. The results of this study showed that the cognitive demand of tasks influenced the level of teacher discourse along with levels of student discourse. Students continued to use the lowest levels of discourse in response to low levels of teacher discourse, cognitive demand of tasks, and discourse interactions. However, students used higher levels of discourse when teachers used high cognitive demand tasks and high levels of teacher discourse. The results of this study also showed that students? use of vocabulary mirrored their teacher?s use of vocabulary. Finally, teachers who used the lowest levels of discourse used technical vocabulary more frequently than their students did and had the highest overall frequency of vocabulary words within their lessons.

<p> Students with Emotional Disabilities (ED) graduate from high school at rates far below their peers. The completed study utilized archival data from former students&rsquo; special education folders and from a nondisabled comparison group to examine variables that had previously been studied in relation to graduation (e.g., repeating ninth grade, extracurricular participation) along with variables identified from the folders of the former students. The descriptive quantitative study identified variables that predicted graduation for individuals with ED and the differences between the variables for individuals with ED and the nondisabled group. The results indicated that GPA and extracurricular participation positively predicted graduation while the number of years spent in 9^th grade negatively predicts graduation for both groups. Specifically for students with ED, student attendance at special education meetings was statistically significant for predicting graduation.</p><p>

<p> <b>Purpose.</b> Following recent federal legislation and related policy changes, co-teaching evolved rapidly as a strategy to provide students with disabilities access to the same curriculum as students without disabilities while receiving instruction in the least restrictive environment. It is unclear if co-teaching is an effective instructional strategy for educating students with disabilities in the least restrictive environment. The purpose of this causal-comparative study was to determine if there was a significant difference in students with disabilities&rsquo; academic performance in co-taught versus traditional classrooms.</p><p> <b>Methodology.</b> This causal-comparative study examined the effects of co-teaching on California students with disabilities&rsquo; performance on the Smarter Balanced assessments. Data were collected from 3 school districts representing 10 comprehensive high schools; 641 test results from the spring 2016 Smarter Balanced assessments of 11th-grade students with disabilities from co-taught and traditional classrooms in English and mathematics were compared using an independent samples <i>t</i> test.</p><p> <b>Findings.</b> Analysis of the 641 Smarter Balanced test results produced the following findings: (a) students with disabilities primarily receive instruction in the traditional classroom; (b) in co-taught classrooms, students&rsquo; primary disability was typically a specific learning disability; (c) <i>t</i>-test results indicated a significant difference in English test scores for students receiving English instruction in co-taught versus traditional classrooms; (d) <i>t</i>-test results indicated no significant difference in mathematics scores for students receiving mathematics instruction in co-taught versus traditional classrooms. </p><p> <b>Conclusions.</b> There is a statistically significant difference in the academic achievement of students in English. While performing lower than students with disabilities in traditional classrooms, students with disabilities in co-taught classrooms received access to the grade-level curriculum in the least restrictive environment. No statistically significant difference in the academic achievement of students in mathematics was noted, suggesting students with disabilities are performing similarly in mathematics regardless of instructional setting. </p><p> <b>Recommendations.</b> It is recommended additional research focuses on the academic achievement of students with disabilities in multiple settings, traditional, co-taught, and special education classrooms, to identify potential variations in achievement related to instructional setting. Additional research may determine the instructional setting&rsquo;s impact on students&rsquo; attitude toward learning, relationships with teachers, or other social-emotional factors.</p><p>

<p> Historically, after-school extracurricular programs can be linked to success in student achievement as well as increased school attendance and giving students &ldquo;safe after-school environments&rdquo; (National Center for Education Statistics, 1995). This causal comparative study investigated student achievement as measured by students&rsquo; grade point average, the number of extracurricular activities the student is involved in, the income status of the student, attendance, as well as gender and grit that the student possesses. The sample included 110 high school seniors, 47% males and 53% females, from the graduating class of 2017 from four rural communities in the Midwest. Participants completed the Grit Scale by Duckworth et al. (2007), which measures an individual&rsquo;s perseverance and passion to continue on to complete one&rsquo;s goals. Analysis of the data centered on the significant interaction effect between grade point average and extracurricular activities as moderated by gender, income, attendance, and perception of grit. The researcher also ran an analysis to see if there was a correlation between grade point average and grit. Results indicated a significant interaction effect between grade point average and extracurricular activities as moderated by income. Results also uncovered a significant interaction effect between grade point average and extracurricular activities as moderated by attendance. Results also showed a significant interaction effect between grade point average and extracurricular activities as moderated by perception of grit. Although there was no significant interaction effect between grade point average and extracurricular activities as moderated by gender, the researcher wanted to validate the research due to the fact this study was happening in a rural community with fewer students involved. There also was a positive correlation when examining grade point average and the score of grit. Future researchers should focus on whether or not the student feels supported. Another focus would be to investigate if students work during the school year and the number of hours that they work during the school week. Co-curricular versus extracurricular activities also need to be explored further within the context of whether they make a difference in a student&rsquo;s grade point average.</p><p>

<p> Public reaction after violent incidents in schools have led policymakers and school officials to institute security measures including zero tolerance policies and police officers. Researchers reported an increase in student arrest rates and exclusionary discipline rates for minor offenses after implementing these initiatives.</p><p> This study focused on student arrest rates and exclusionary discipline measures in two high schools among School Resource Officers (SRO)/School Based Police Officers (SBPO) and secondary administrators over two school years. Furthermore, the study examined the factors influencing arrest decisions of the School Resource Officers/School Based Police Officers involved. The data collected answered these questions: 1. What factors contribute to the School Resource Officers'/School Based Police Officers' decisions of whether to arrest students in the school setting? 2. How do zero tolerance approaches influence student arrest rates and student exclusionary discipline rates in schools that utilize School Resource Officers/School Based Police Officers? 3. What role do the School Resource Officers/School Based Police Officers have in the school environment?</p><p> A descriptive research method, utilizing interviews, surveys and student arrest and discipline information, was used to answer these questions. The participants in this study were selected using purposive sampling based on their assignment in a secondary school.</p><p> This study reported that there were similarities among the police officers regarding the factors affecting the arrest decisions. This was reasonably consistent with the research. Most students in the study were arrested at both site locations for minor misconduct in 2014-15 but major offenses in 2015-16. The exclusionary discipline rates were dependent on site location. This appeared to be an indication that it had little to do with the SROs/SBPOs assigned to the schools and much more to do with the administrative leadership within the respective schools.</p><p> The findings indicate a need for ongoing collaboration and communication between the supervisors of the schools and law enforcement agencies. Furthermore, the implementation of a positive approach to student behavior rather than a punitive approach may assist in reducing the amount of exclusionary outcomes. Lastly, training for the police officers related to interactions with misbehaving students may assist in changing their arrest decisions.</p><p>

<p> The purpose of this correlational study was to examine the relation between student engagement and reading attitude in an online high school learning environment using the High School Survey of Student Engagement (HSSSE) and the Rhody Secondary Reading Attitude Scale (Rhody). Subjects were administered the HSSSE and Rhody as a single survey electronically using Google Forms during the Fall 2016 semester. All subjects were enrolled in at least one online course at the time of the survey administration. A MANOVA was run to analyze the data for each research question and sub-question. Although this research found there to be no statistically significant correlation between student engagement and reading attitude in the online high school environment used for this study, the results provided a few strong trends: the relation between the number of online courses a student had previously taken and emotional student engagement and the relation between the number of online courses a student had previously taken and overall student engagement. This research found overall trends that contradict the results of research done in traditional high school learning environments, but support previous research done in online high school learning environments.</p><p> These substantial trends influence the development and implementation of policies and procedures of online high school learning environments in order to increase student engagement (behavioral, emotional, and cognitive). Although this dissertation has distinguished these essential trends, future research must investigate student characteristics and environmental factors to identify elements that lead to increased student engagement (behavioral, emotional, and cognitive).</p><p>

<p> This dissertation explores how pre-service teachers conceptualize the relationship between justice and practice, and then navigate the tensions of their student teaching context to enact their beliefs in their teaching practice. Starting from the assumption that all teachers must understand how their practice challenges rather than reproduces inequities, this proposal&rsquo;s theoretical framework explicates four elements of a social justice educator: an orientation towards justice, a critical frame for understanding the relationship between macro-level structures and micro-level interactions, and conceptual and practical tools to live this in one&rsquo;s practice/praxis. A literature review of Social Justice Teacher Education (SJTE) and Practice-based Teacher Education (PBTE) along these four dimensions suggests complementary possibilities for facilitating the preparation of social justice educators. The qualitative study, leveraging practitioner research methodologies, how pre-service teachers developed the conceptual and practical tools of social justice educators. Findings pre-service teachers suggest that pre-service teachers varied in their conceptualizations of how teachers acted towards more just outcomes, and in their relation of their teaching aims to the real world. Additionally, pre-service teachers responded to tensions they countered in their particular school context by planning and enacting units of instruction that fulfilled their teaching aims, responded to the contextualized tensions, reflected their conceptualizations of justice, and met their students&rsquo; needs.</p><p>

<p> This study aimed to understand how 35 focal students in a No Excuses high school, a charter school model designed to promote social mobility, made decisions about if and where to go to college. This study draws on college choice, cultural capital, and performance management literature to understand how the high school context at the focal school influenced students' college choice processes. Drawing on data from interviews, observations, and documents, this exploratory study found that Performance High provided extensive college resources and support to its students, which was consistent with how researchers conceptualize a "college-going culture" in high schools. Further, the high school used a performance management approach, in which administrators held teachers and students accountable for meeting particular college related metrics, such as the number and types of applications students were required to submit. The study found that focal students submitted applications and enrolled in college at high rates. Thirty-four of the 35 focal students planned to attend college the following fall. However, rather than exhibit the sense of entitlement and expectation that research describes for students who benefit from dominant forms of cultural capital, most of the focal students' college choice processes were characterized by hesitation, ambivalence, and doubt. Further, the findings suggest the performance management approach assimilated students to one model of college choice that did not easily accommodate students' preferences. These findings highlight the difficulties for schools in providing cultural capital for students independent of their families, and suggests the need to reconceptualize "college-going cultures" to not only consider the college outcomes and the density of resources in the high school context, but how well students absorb cultural capital, which may be important for social mobility. </p>

<p> The purpose of this study was to investigate the effects of vibrato and pitch-varied vocal models on acoustic measures of high school and undergraduate singers&rsquo; vocal performance. Participants&rsquo; perception of vocal models was also examined to explore a possible relationship between perception and production. The following primary questions guided this research: 1) Is singers&rsquo; intonation affected by vibrato or pitch-varied vocal models? 2) Is singers&rsquo; vibrato rate affected by vibrato or pitch-varied vocal models? 3) Is singers&rsquo; vibrato extent affected by vibrato or pitch-varied vocal models? 4) Is singers&rsquo; intensity affected by vibrato or pitch-varied vocal models? Secondary questions under investigation were: 1) Do singers respond differently to vocal models of pitch patterns versus song phrases? 2) Does age and experience influence singers&rsquo; response? 3) Do singers perceive the differences in vocal models? </p><p> Participants (<i>N</i> = 76) were male (<i>n</i> = 38) and female (<i>n</i> = 38) singers who were undergraduates (<i>n</i> = 40) currently participating in a choral ensemble at the Florida State University or high school students (n = 36) currently enrolled in the choral program at a nearby high school. Participants responded to twelve vocal models of the same gender that were varied in melody, vibrato, and intonation conditions. Vocal models consisted of either a short pitch pattern (<i> sol-la-sol-fa-mi-re-do</i>) or familiar song excerpt (Are You Sleeping?), both performed on the neutral syllable <i>&ldquo;tah.&rdquo;</i> Model melodies were sung in vibrato and minimal vibrato conditions, with each model having a specific 3rd and 5th scale degree that was presented in tune, sharp, or flat (mistuned pitches &plusmn; 25 cents relative to equal temperament). After responding to vocal models, participants were asked via written questionnaire if they perceived differences in vocal models and, if so, to describe them. </p><p> Audio recordings of participants&rsquo; responses were analyzed acoustically, with the specific 3rd and 5th scale degrees in each model analyzed for the dependent measures of intonation, vibrato rate, vibrato extent and intensity. Repeated measures analyses were conducted on the acoustic measures. An alpha level of .01 was used in all statistical tests. Written responses on the questionnaire were analyzed for keywords reflecting vocal technique or musical elements. Keywords were then identified and coded for frequency of response. </p><p> Significant differences in intonation were found, with responses to minimal vibrato models performed more flat than responses to vibrato models. Main effects were also found for gender, with male participants showing overall more flatness than females. Responses to pitch-varied models tended towards flat intonation, with flat models producing the greatest deviation particularly with male participants. Two interactions, both involving melody condition of models, also produced differences in intonation. </p><p> Significant differences in measures of vibrato rate and extent were also observed. Vibrato rates were faster and vibrato extents were wider in response to vibrato models. High school participants responded with similar vibrato rate and extent to both vibrato model conditions, whereas undergraduates responded with significantly faster vibrato rate and wider extent to vibrato models. Undergraduate vibrato rates were similar between genders, however high school males were significantly slower in vibrato rate than high school females. </p><p> Intensity results for both high school and undergraduate participants showed significantly higher intensity levels for 5th scale degrees than 3rds. High school males performed both scale degrees at similar intensity levels, while high school females sang 5ths with higher intensity. Significant differences in intensity were also found with undergraduates, with responses to vibrato models yielding higher intensity. Male undergraduates were found to sing with higher intensity in response to vibrato models, whereas females sang with similar intensity between vibrato-varied conditions. Interactions involving scale degree or melody condition of models also produced significant differences in intensity. </p><p> Analysis of written questionnaires showed that 71 (93%) participants perceived differences in models. The most frequently used keyword(s) was <i> vibrato/straight tone,</i> with 36 participants (51%) noting this as a perceived difference between models. <i>Timbre/tone quality</i> was the next most used word(s) by 13 participants (17%), followed by <i> intonation/pitch</i> used by 12 participants (15%). More males noticed changes in tone quality, intonation, and vowels than females, whereas the latter recognized vibrato changes more than males. Undergraduates perceived vibrato changes and intonation differences more than high school participants. </p><p> Many complex factors were thought to contribute to results of this study, including perception, experience, vocal development, and vocal production. While some findings support prior research, other results raise questions that warrant additional investigation. Implications and ideas for future inquiry are discussed.</p>

<p> Although many teachers use concurrent instructional strategies, little is known about how or when they function in rehearsal, or how frequently they are employed. The purpose of the present study was to examine pitched and unpitched concurrent instructional behaviors as they occurred naturally in secondary choral rehearsals over time. Three master teachers (two male, one female) with at least 10, 20, and 30 years of teaching experience, respectively, recorded their rehearsals over the course of approximately six weeks, from the introduction of a new piece of literature, through the point in time when it is deemed &ldquo;performance-ready&rdquo; by the director. Data were recorded, on average, twice per week, in the form 15&ndash;20 minutes of audio footage, and sent to the researcher for analysis. Results indicate that mean concurrent instruction was present for 25.88% of a given rehearsal. The most frequently used pitched behavior was singing and the most frequently used unpitched behavior was the academic hustle. Potential implications for music education practitioners and directions for future research are discussed. </p><p>
