Abstract

Purpose

Recent teacher evaluation reforms around the globe substantially increased the number of teacher observations, consequently raising observers' (typically school administrators') observational loads. The purpose of this study is to examine associations between observational loads and school administrator turnover, reported time use and strain.

Design/methodology/approach

The study uses education administrative data from the state of Tennessee to examine the link between observational loads and school administrator outcomes of interest. The results present credible regression estimates that isolate variation in observational loads within schools over time and within observers over time.

Findings

The evidence suggests individual school administrators allocate a set amount of time to observations that is insensitive to observational load and seemingly assign observations to colleagues strategically. School administrator reports do not suggest observational loads are associated with negative unintended consequences on administrator strain or observer turnover.

Originality/value

The study contributes to the literature on teacher evaluation by shedding light on how the constraints posed by an evaluation system may affect the work of school administrators. It also extends the job demands-resources theory that describes worker responses to new job demands.

Abstract

Purpose

The purpose of this study was to explore the utility of a virtual reality (VR) classroom experience for improving the capacity of instructional leaders. Specifically, school leaders used VR to build their classroom observation and analysis skills to prepare to have more effective post-observation conversations with teachers. The authors provide insights from multiple data points that highlight the affordances of the virtual setting for improving classroom observation skills.

Design/methodology/approach

Drawing on the application of simulations to practice classroom observations, the authors developed a VR experience in which participants tag observable elements of academic discourse using codes from two observation protocols. The protocols identify elements of equitable student access: how teachers call on students and how they design questions. Seventy-five school leaders used the VR platform to observe a classroom scenario and code evidence of equitable classroom access. The authors analyzed data from tagging in the virtual reality scenario and triangulated these data with survey data focused on observation practices from participants' schools. A reflection component is included on the platform to collect these qualitative data.

Findings

The study results indicate that the virtual reality platform provides an innovative process for leadership professional development focused on building school leaders' capacity to identify elements of academic discourse during classroom observations. Participants reported that the opportunity to practice classroom observations in a risk-free environment was useful. However, for school leaders to fully transfer the data to using in conversations with teachers, they benefit from leadership coaching.

Originality/value

This study ascertains the potential effectiveness of an advanced technology for enhancing instructional leadership by using evidence-based classrooms observations to drive improvements in teaching practice. Beyond the utility of the virtual reality tool, this study provides a proof of concept for the next generation of instructional leadership through teacher observations with augmented reality.

Abstract

Several studies have observed that stocks tend to drop by an amount that is less than the dividend on the ex-dividend day, the so-called ex-dividend day anomaly. However, there still remains a lack of consensus for a single explanation of this anomaly. Different from other studies, this dissertation attempts to answer the primary research question: how can investors make trading profits from the ex-dividend day anomaly and how much can they earn? With this goal, I examine the economic motivations of equity investors through four main hypotheses identified in the anomaly's literature: the tax differential hypothesis, the short-term trading hypothesis, the tick size hypothesis, and the leverage hypothesis.

While the U.S. ex-dividend anomaly is well studied, I examine a long data window (1975–2010) of Thailand data. The unique structure of the Thai stock market allows me to assess all four main hypotheses proposed in the literature simultaneously. Although I extract the sample data from two data sources, I demonstrate that the combined data are consistently sampled. I further construct three trading strategies – “daily return,” “lag one daily return,” and “weekly return” – to alleviate the potential effect of irregular data observation.

I find that the ex-dividend day anomaly exists in Thailand, is governed by the tax differential, and is driven by short-term trading activities. That is, investors trade heavily around the ex-dividend day to reap the benefits of the tax differential. I find mixed results for the predictions of the tick size hypothesis and results that are inconsistent with the predictions of the leverage hypothesis.

I conclude that, on the Stock Exchange of Thailand, juristic and foreign investors can profitably buy stocks cum-dividend and sell them ex-dividend while local investors should engage in short sale transactions. On average, investors who employ the daily return strategy have earned significant abnormal return up to 0.15% (45.66% annualized rate) and up to 0.17% (50.99% annualized rate) for the lag one daily return strategy. Investors can also make a trading profit by conducting the weekly return strategy and earn up to 0.59% (35.67% annualized rate), on average.

Abstract

Classroom management is a prerequisite for effective instruction, yet research indicates that not all teachers implement evidence-based classroom management skills (CMS) in their classroom. Therefore, efficient professional development models are necessary to increase teachers’ use of CMS, but those models are predicated on valid and reliable screening tools to identify teachers CMS performance. This study is a psychometric evaluation of a direct observation CMS screening tool for elementary school teachers that can be used as part of a targeted CMS professional development model. Based on a three-facet generalizability study, the primary source of variance across observations was differences among teachers and differences across observations. A decision study was conducted and indicates that a generalizable estimate from the CMS screening tool requires four 30-min observations. These results are compared with prior research and recommendations for future research are discussed.

Abstract

This chapter focuses on the ethnographic research approach that I employed in a service marketing study. The first part briefly describes ethnography’s key characteristics, that is, emergent research logic, prolonged fieldwork, and multiple modes of data collection, where the main method is observation. The second part discusses the data collection methods: participant observation, informal discussion, interview, and document analysis. This section describes in detail how these techniques were used in practice and highlights the key challenges I faced, especially related to the observations, and how I managed these challenges. The third part describes the case, field setting, informants, and field relationships. The development project that I studied concerned a bank’s website and project members from the bank and different consultant agencies represent the study’s informants. The fieldwork lasted for about one year and covered the entire development process from the initial stages to the launch, and some time after. The chapter ends with a thorough discussion about the research criteria of validity, reliability, and generality, and the coping tactics that I used in this study to enhance these. Prolonged fieldwork, multiple modes of data collection, reflexivity, and specification of the research are among those important tactics that this last section discusses in detail.

Abstract

For this discussion, assume there are n sample observations of the dependent variable y at unique locations. In spatial samples, often each observation is uniquely associated with a particular location or region, so that observations and regions are equivalent. Spatial dependence arises when an observation at one location, say y i is dependent on “neighboring” observations y j, y j∈ϒi. We use ϒi to denote the set of observations that are “neighboring” to observation i, where some metric is used to define the set of observations that are spatially connected to observation i. For general definitions of the sets ϒi,i=1,…,n, typically at least one observation exhibits simultaneous dependence, so that an observation y j, also depends on y i. That is, the set ϒj contains the observation y i, creating simultaneous dependence among observations. This situation constitutes a difference between time series analysis and spatial analysis. In time series, temporal dependence relations could be such that a “one-period-behind relation” exists, ruling out simultaneous dependence among observations. The time series one-observation-behind relation could arise if spatial observations were located along a line and the dependence of each observation were strictly on the observation located to the left. However, this is not in general true of spatial samples, requiring construction of estimation and inference methods that accommodate the more plausible case of simultaneous dependence among observations.

Abstract

This chapter focusses on the complexity of observation, considering its role in lesson study, following a broader discussion of how observation is generally understood in teaching contexts. The authors argue that lesson study observation is formative and should not be performative in focus. In lesson study cycles, observation is a process conducted among peers ideally in a spirit of mutual support and collaborative inquiry, seeking to find answers to pedagogic challenges rather than measuring the effectiveness of individual teachers.
