Implementing Walkthroughs: One School's Journey

Payne, Elizabeth T. 20 January 2011 (has links)
In order to support the new mission of education where students achieve at high levels, schools need infrastructure, in terms of processes, procedures, and capacity building, to support the collaboration between administrative instructional leadership and teachers' professional development with the goal of student learning and achievement. Walkthroughs are a tool used throughout school districts with a limited base of research. This mixed methods case study describes one middle school's journey with walkthroughs. This dissertation explores and describes three main aspects of walkthroughs: process, perspectives, and recommendations. Administrators and teachers shared their experiences through personal interviews, focus group interviews, the Concerns Based Adoption Model Stages of Concern Questionnaire, and documents. Findings suggest that classroom walkthroughs work best in school climates that have an established level of trust between administrators and teachers. Walkthroughs, with classroom observations led by all teachers in the school, allow teachers to engage in professional dialogue about expectations for teaching and learning for all students in all content settings. Walkthroughs are a process that takes time to implement, should be ongoing, and require a transparent flexible process to meet individual school needs. If the need or expectation is to change teaching practices, then teachers need to be involved in all aspects of instructional supervision in collaboration with administrators on a continual basis. / Ed.

Classroom Observation Of Children With Adhd And Their Peers: A Meta-analytic Review

Kofler, Michael 01 January 2006 (has links)
Meta-analysis of 23 between-group direct observation studies of children with ADHD and typically developing peers indicates significant deficiencies in children with ADHD's ability to pay attention in classroom settings. Comparison with 59 single case design studies of children with ADHD suggests generalizability of between-group comparisons. Weighted regression analysis determined that several methodological differences – sample characteristics, diagnostic procedures, and observational coding schema – have significant effects on observed levels of attentive behavior in the classroom. Best case estimation indicates that after accounting for these factors, children with ADHD are on-task approximately 65% of the time compared to 85% for their classroom peers. Children with ADHD were also more variable in their attentive behavior across studies. Implications for conceptual models of ADHD are discussed.

Elementary School Principals’ Perceptions of Mathematics Instruction and its Role in their Teacher Evaluation Processes

Humez, Andrea Loren January 2015 (has links)
Thesis advisor: Laura M. O'Dwyer / This mixed-methods study analyses data from interviews with 29 principals in four school districts, to describe patterns in the principals’ values concerning high-quality mathematics instruction and in the aspects of instruction they noticed when observing short videos of elementary school mathematics classes. Principals valued many aspects of instruction, including elements of general pedagogy, teachers interacting with content and students, content-related pedagogy, students interacting with content, and evidence of student outcomes. As a group, principals noticed the same types of instructional elements that they valued, as well as other, less-commonly-valued elements. Hierarchical linear models were used to compare ratings given to teachers by their principals on three aspects of instructional effectiveness, to scores from video- and student-test-score-based measures of corresponding constructs. Mathematical Quality of Instruction, Classroom Assessment System™ and value-added scores each accounted for unique portions of variance in teachers’ scores on a composite principal rating scale, showing that the underlying “high-quality mathematics” construct measured by principals had some elements in common with each of the other three constructs. However, substantial variance remained unaccounted for, suggesting that principals’ concept of high-quality mathematics also comprises elements not measured by any of the other three instruments. / Thesis (PhD) — Boston College, 2015. / Submitted to: Boston College.

Training Noise-Robust Spoken Phrase Detectors with Scarce and Private Data: An Application to Classroom Observation Videos

Zylich, Brian Matthew 25 April 2019 (has links)
We explore how to automatically detect specific phrases in audio from noisy, multi-speaker videos using deep neural networks. Specifically, we focus on classroom observation videos that contain a few adult teachers and several small children (< 5 years old). At any point in these videos, multiple people may be talking, shouting, crying, or singing simultaneously. Our goal is to recognize polite speech phrases such as "Good job", "Thank you", "Please", and "You're welcome", as the occurrence of such speech is one of the behavioral markers used in classroom observation coding via the Classroom Assessment Scoring System (CLASS) protocol. Commercial speech recognition services such as Google Cloud Speech are impractical because of data privacy concerns. Therefore, we train and test our own custom models using a combination of publicly available classroom videos from YouTube, as well as a private dataset of real classroom observation videos collected by our colleagues at the University of Virginia. We also crowdsource an additional 1152 recordings of polite speech phrases to augment our training dataset. Our contributions are the following: (1) we design a crowdsourcing task for efficiently labeling speech events in classroom videos, (2) we develop a neural network-based architecture for speech recognition, robust to noise and overlapping speech, and (3) we explore methods to synthesize new and authentic audio data, both to increase the training set size and reduce the class imbalance. Finally, using our trained polite speech detector, (4) we investigate the relationship between polite speech and CLASS scores and enable teachers to visualize their use of polite language.

Hänsyn till helheten : extrahering av en didaktisk modell för det komplexa innehållet i den naturorienterande undervisningen på lågstadiet

Weiland, Maria January 2019 (has links)
This study focuses on science education in primary school. The aim is to systematize and exemplify the content in primary science, not only scientific content but everything surrounding teaching in science, in the forms of a didactical model. The study was performed in grades 1-3 (ages 7-10) in a Swedish primary- and lower secondary school. Four primary school teachers and their classes were followed in their teaching in science education. The empirical data consists of field notes, video- and audio recordings from in total 17 science lessons. The results show how science education in primary school contains much more than just teaching a scientific content. The results also show how teachers, in relation to, and simultaneously with, the scientific content, also teach students in speaking, reading, writing and in social interaction with others. The three types of content areas that were identified were systematized into a didactical model called ‘didactic score’. The didactic score highlights that all these parts in the teaching situation is performed simultaneously, but that different parts may be fore fronted and other parts may be put in the background during the process of teaching. The teacher has a prominent role in directing the students’ attention towards the different parts in the didactic score, in order to give the students conditions for creating continuity in the learning process.

Classroom Observations of Instructional Practices and Technology Use by Elementary School Teachers and Students in an Ethnically-and Economically-Diverse School District

Rollins, Kayla Braziel 2011 August 1900 (has links)
The purpose of this study was to observe pre-kindergarten through fifth-grade public school classrooms to examine differences among instructional practices and technology use by teachers, students and the overall classroom. The current study differed from and built upon previous classroom observational research in a number of major ways. First, the observational data examined both student and teacher technology use and the availability of technology in the classroom. Second, authentic classroom behaviors were examined in relation to technology use; specifically, behaviors related to the impact of technology use on student engagement as well as differences among technology use in classrooms and differences by student socio-economic status. Finally, unlike previous studies, this study focused specifically on pre-kindergarten through fifth-grade classrooms from the same large public school district that was diverse by both socio-economic status (SES) and by student ethnicity. Overall, the results of this study suggest that technology has not been adequately implemented into the observed classrooms. Technology was available but was not used to a great extent. When technology was implemented, teachers were primarily observed using it to present material and students were observed using it almost exclusively for basic skills activities. This low-level of technology integration occurred in elementary schools of a high performing school district which had a technology plan in place, a low student to computer ratio, and 100 percent of the classrooms had Internet access. Furthermore, only 15 percent of teachers were observed integrating technology to a great extent; however, students in these classrooms were observed on task significantly more frequently than students in classrooms where technology was observed less or not at all. On the other hand, students were observed off task significantly more in classrooms where either no technology integration was observed or where it was only observed a moderate amount. These findings support and build upon previous observational studies. There is still a need, however, for strong, empirical research to be conducted to further examine the use of technology in elementary classrooms.

More Than a Sum of its Parts: Five Fundamentals for Formative Peer Observation of Classroom Teaching in Higher Education

McCloud, Jonathan David 08 December 2015 (has links)
This dissertation comprises two manuscripts formatted for publication, preceded by a brief introduction to the dissertation project. The first manuscript addresses the recent history and development of peer observation in the United States and synthesizes the body available peer observation scholarship. Five fundamental elements of peer observation (design, community, control, training, reflection) are put forth as a nexus at which meaningful and formative peer observation can be undertaken. A selection of empirically based methods for conducting peer observation is also presented. The second manuscript is a mixed-methods descriptive study of the five fundamentals of peer observation. Three academic departments at a large land-grant university were identified, via questionnaire, as having programs of peer observation that aligned with attributes of the five fundamentals. These academic departments participated in individual case studies designed to bring-about a description of the five fundamentals as they were and were not manifest in authentic university/college contexts. / Ph.

Becoming an activist Chicana teacher: a story of identity making of a Mexican American bilingual educator in Texas

Jackson, Linda Dolores Guardia 23 November 2009 (has links)
This person-centered ethnography focused on the ways one exemplary veteran Mexican American bilingual educator’s (MABE’s) cultural resources and professional experiences influenced her teaching practices. The study examined her life history and classroom practices to explore the trajectory of her identity making. The framework utilized in this research included a sociohistorical/sociocultural lens and Chicana/Latina feminist theories. Specifically, my research investigated the multiple spaces where a MABE navigated between an additive bilingual education model and a subtractive one. The study relied primarily on data collected from oral life history interviews augmented by participant observations at a school in a large, central Texas district. The participant, a first grade teacher with 28 years of classroom experience in the same district, was interviewed over a four-year span. Further, classroom observations occurred during a full school year. Additional interviews with educators who worked with the participant at critical moments in her professional life provided not only triangulation of information, but also a multiplicity of perspectives and foci on the educational landscapes wherein she operated. Narrative analysis of the data involved the decoding and deconstruction of a MABE’s active participation in the processes of performing and (re)presenting her identity production including being silenced and speaking up. The findings revealed a dialectic and dialogic process between personal experiences, early schooling, impositions of policies, and daily-lived classroom experience while constantly navigating and negotiating the challenges of educating culturally and linguistically diverse students. A primary finding revealed the construct of autobiographical consciousness as a MABE’s critical awareness of the historical legacy, lived experiences, and the contexts in which she teaches. The study documented silencing through marginalization, as well as establishing voice through agency to understand construction and reconstruction of identities. / text

Incorporating engineering specificity in the UTeach Observation Protocol

Martin, Spencer Holmes 10 October 2014 (has links)
The UTeach Observation Protocol (UTOP) is designed to capture what occurs in a classroom. The UTOP was developed for use in the nationally recognized UTeach program (uteach.utexas.edu) and has been validated nationally in the Gates Foundation Measures of Effective Teaching. (http://www.metproject.org/downloads/Preliminary_Findings-Research_Paper.pdf) Currently the UTOP has been used in both science and math classrooms and is being developed for use in English language arts and social studies classrooms as well. This report serves to begin the modification of the UTOP for use in an engineering classroom to evaluate engineering specific content. The UTOP has been described as a lens for reflection on teaching practices and the goal of this report is to help focus that lens more clearly on the engineering classroom. This tool was created for utilization in both educator and administrator roles. Teachers can use the UTOP to self-assess their own teaching practices as well as in observing other teachers and identify classroom best practices. Administrators and other classroom visitors can use the UTOP to understand and evaluate what occurs in a classroom for a multitude of outcomes. The methodology chosen in this report to create the engineering specific examples used real lessons that have been implemented in engineering classrooms and vetted in actual practice. Using both initial lessons from the teachers and their feedback along with language taken from the Next Generation Science Standard Framework and the UTeachEngineering Engineering Design Protocol, the examples were developed to show how to score each indicator on a scale of 1 to 5, with 1 being the lowest and 5 being the highest score, in a secondary engineering classroom. The next steps recommended for this work are to pilot the examples created in this report and test the usefulness of the examples created. This can be accomplished by field-testing it in UTOP training with teachers and modifying the information based on the feedback that they provide. The work described in this paper was made possible by a grant from the National Science Foundation (Award DUE-0831811). / text
