Teachers in a New Jersey suburban high school noticed an increase in students' stress and anxiety associated with high-stakes testing, and they were struggling to find strategies and interventions to help. The purpose of this study was to investigate high school English and mathematics teachers' current knowledge, experiences, and perceptions about students' preparation and responses to high-stakes testing and to explore teachers' perceptions about teaching strategies they needed to reduce student test anxiety. Liebert and Morris's bidimensional components of anxiety, emotionality, and worry form the conceptual framework that guided this study. The research questions focused on teachers' perceptions about students' high-stakes testing readiness, students' testing behaviors, and teachers' training needs. A case study design was used to capture the insights of 12 high school English and math teachers through semistructured interviews and a focus group interview; a purposeful sampling process was used to select the participants. Emergent themes were identified through open coding, and the findings were developed and checked for trustworthiness through member checking, rich descriptions, and researcher reflexivity. The findings revealed that teachers recognize that students react in different ways to testing, that students who are prepared for the tests demonstrate greater confidence and less anxiety, and that teachers want more professional development specific to reducing students' anxiety and stress. A professional development project was created to provide teachers with strategies and approaches to prepare students for high-stress testing situations. This study has implications for positive social change by creating a structure to provide teachers with strategies for managing students' test anxiety.

Στην εργασία χρησιμοποιούνται σήματα καρδιακού ρυθμού, τα οποία αντιστοιχούν σε φυσιολογικές και οξαιμικές περιπτώσεις.Στην συνέχεια αυτά τα σήματα τα επεξεργαζόμαστε με διάφορες τεχνικές. Στόχος της εργασίας αυτής είναι ο διαχωρισμός των δυο αυτών ομάδων. / In this thesis are used signals of cardiac rythm, that correspond in physiologic and oxidemic cases.Then we processed these signals with various techniques.Target of this thesis is the segregation of this two teams.

This mixed methods study examined relationships between third, fourth, and fifth grade teacher attendance as well as teacher and administrator perceptions of teacher attendance during the 2005-06, 2006-07, and 2007-08 school years. Third, fourth, and fifth grade student test scores on the Tennessee Comprehensive Assessment Program (TCAP) Achievement test given in the spring of 2006, 2007, and 2008 were also examined. TCAP score data for this study were gathered electronically, with published data from the Tennessee Department of Education. Teacher attendance records were collected using Siesta, a teacher attendance tracking program. Teacher and administrator perceptions were gathered through surveys, interviews, and focus groups. The population for this study included five K-5 schools and two K-8 schools in a small, rural, public school system in Tennessee. All students in grades 3 through 8 take the TCAP test each spring. Students must take a total of 4 subtests. Quantitative variables were analyzed using descriptive statistics including t tests, analysis of variance (ANOVA), Mann Whitney U, and Pearson correlations. Qualitative data including interviews, focus groups, surveys, documents, handbooks, and school calendars were analyzed to better understand teacher and administrator perceptions about teacher absences. The results of this study were mixed. Teachers and administrators who participated in this study agreed that teacher absences do affect student test scores, but the quantitative data did not support this. The null hypotheses were retained in all courses and grades except third grade Math. This means there was no relationship between teacher absences and student test scores.
