Overwhelming evidence supports the fact that music instruction greatly increases academic achievement on standardized test scores at the elementary, middle and high school level. When school districts face budget deficits, typically they alleviate the shortfall by eliminating music programs. Currently in Dallas ISD, teacher salaries are affected by how well a student performs on the STAAR exam. In this quantitative, causal-comparative study, 5th grade music STAAR mathematics scores are investigated to discover if instrumental music instruction using the Little Kids Rock Modern Band method improves academic achievement on the STAAR exam.

Using an exploratory case study approach, this study examined the school leadership factors that contribute to building Latinx student social capital as well as the best practices for creating a more equitable AP program. Through this qualitative study, the organizational and leadership factors of the AP program at Stripes High School (pseudonym) were examined, and how these factors contributed toward closing the opportunity gap. This study used semi-structured interviews with district and campus leaders and an AP teachers focus group to determine leadership beliefs and actions that were successful in building an accessible and equitable advanced academics program for Latinx students, as well as an AP student focus group to triangulate the findings. The results of this study showed Latinx students, already lacking social capital, also face many barriers of different forms: systemic, structural and cultural in their educational opportunities for AP courses and exams. The case study campus overcame these barriers and increased equity by allowing Latinx students more access to AP courses and exams through district- and campus-level administrators working to remove barriers and hire and support the most capable and socially aware AP teachers who aim to grow and nurture the students who they serve. Based on …

The rapid expansion of computers and digital technology requires citizens to be digitally literate. Teachers must prepare students for a digital world despite the lack of consensus on a definition or its components. This multiple case study explored the digital literacy instruction and interactive decision making of teachers with varied levels of expertise. Each participant completed a survey and the General Decision Making Style Questionnaire prior to a series of interviews and classroom observations. Findings from a qualitative analysis of the data suggest variations in the use of digital literacy components during instruction and that skills are related to one another. Findings also indicate similarities and differences in interactive decision making and teaching expertise behaviors related to instruction. Based on these findings, recommendations to better promote digital literacy are directed toward teachers, administrators, teacher preparation institutions, and future researchers. Current events emphasize the need for increased efforts in turning the key of digital literacy for students.

There is increasing evidence indicating that exposure to air pollutants may be associated with the onset of several respiratory diseases such as allergic airway disease and chronic obstructive pulmonary disorder (COPD). Many lung diseases demonstrate an outgrowth of pathogenic bacteria belonging to the Proteobacteria phylum, and the incidence of occurrence of these diseases is higher in heavily polluted regions. Within the human body, the lungs are among the first to be exposed to the harmful effects of inhaled pollutants and microbes. Research in the past few decades have expounded on the air-pollution-induced local and systemic inflammatory responses, but the involvement of the lung microbial communities has not yet been well-characterized. Lungs were historically considered to be sterile, but recent advances have demonstrated that the lower respiratory tract is replete with a wide variety of microorganisms - both in health and disease. Recent studies show that these lung microbes may play a significant role in modulating the immune environment by inducing IgA and mucus production. Air pollutants have previously been shown to alter intestinal bacterial populations that increase susceptibility to inflammatory diseases; however, to date, the effects of traffic-generated air pollutants on the resident microbial communities on the lungs have not …
