Racial Profiling Policy And Its Relation To Pro-Active Policing, Bradley R. Anders
Racial Profiling Policy And Its Relation To Pro-Active Policing, Bradley R. Anders
Walden Dissertations and Doctoral Studies
To address the primary problem of racial profiling by police, many states have passed legislation that require police departments to collect demographic data on those with whom the officer comes into contact; these data are later evaluated by supervisors. The problem lies in the possibility for police officers to disengage, or depolice, when faced with data collection policies that may be viewed as lessening the officer's discretion. It was this potential to depolice as related to policy interpretation that formed the conceptual framework for this study. As a result, implementation of racial profiling policies may negatively impact the very minorities …

Augmentative And Alternative Communication Systems In The Classroom, Helen Angela Mezzomo
Augmentative And Alternative Communication Systems In The Classroom, Helen Angela Mezzomo
Walden Dissertations and Doctoral Studies
Augmentative-alternative communication (AAC) systems are used to give voice to individuals who are nonverbal. As AAC systems become more complex and prevalent in the classroom expectations of school-based professionals expand. However, the roles of those expected to support AAC systems, primarily teachers and speech-language pathologists (SLPs), are not clearly defined. Without clearly defined roles, professionals may not provide needed support to students who use AAC. Dewey's theory of community suggests that role confusion leads to insufficient and ineffective services. The purpose of this cross-sectional quantitative study was to determine how teachers and SLPs view their roles in supporting AAC. The …

Professional Development For K--12 Charter School Teachers In Jersey City: Effects On Student Achievement, Davidson Okere
Walden Dissertations and Doctoral Studies
Continuous workforce training programs are important for business productivity. Traditional professional development practices (those that make teachers passive consumers of knowledge) may no longer satisfy the need for teachers' professional growth and for student achievement as measured by test scores. The purpose of this quantitative, nonexperimental study was to consider the importance of professional development and collegiality (teacher collaboration) on student achievement. This study was based on Piaget's constructivism. The research question asked whether teachers thought collegial professional development and management's support helped teachers improve student achievement based upon the type of professional development (PD) employed at their schools. The …
