Latent Differential Equation Models for Binary and Ordinal Data

This study evaluates latent differential equation models on binary and ordinal data. Binary and ordinal data are widely used in psychology research and many statistical models have been developed, such as the probit model and the logit model. We combine the latent differential equation model with the probit model through a threshold approach, and then compare the threshold model with a naive model, which blindly treats binary and ordinal data as continuous. Simulation results suggest that the naive model leads to bias on binary data and on ordinal data with fewer than 5 levels, whereas the threshold model is unbiased and efficient for binary and ordinal data. Two example analyses on empirical binary data and ordinal data show that the threshold model also has better external validity. The R code for the threshold model is provided.     

Placing PISA and PISA for schools in two federalisms,Australia and the USA

ABSTRACT

This paper accepts that the OECD’s PISA has become influential in policy terms globally, but analyses the ways that the main PISA and PISA for Schools tests are positioned differently in Australia and the USA because of contrasting educational federalisms in the two nations. Our argument is that while PISA is undoubtedly influential, its effects are nonetheless mediated by the political structures – here, the different models of federalism – present within different nations, which in turn leads to quite distinct ‘PISA effects’. For instance, Australia oversamples on main PISA to make its data available for national and state-level policymaking, whereas the USA, with its focus on local governance in schooling, does not oversample, meaning that main PISA does not have a comparable policy salience as in Australia. Conversely, the newer PISA for Schools test originated in the USA with pressure from educators and philanthropic interests and has been implemented in a good number of schools, but it has not been taken up in the same way in Australia. Our analyses show how these differences reflect the idiosyncratic workings of federalism in the two nations, in which the federal government has a stronger policy and funding role in Australia than has hitherto been the case for the federal government in the USA.     

Design Dynamics of a Leadership Assessment Academy: Principal Self-Assessment Using Research and Technology

This article describes and analyzes the design dynamics of a school principal self-assessment process, provided through a three-day, state-approved Leadership Assessment Academy, which allows principals to experience and reflect on important self-assessment data that leads to a personal professional growth plan. Designing and implementing such an academy is complex and requires careful consideration of all aspects of the principalship and the requirements set forth by the state regarding principal assessment and professional growth plans. A primary challenge of this leadership academy is in providing principals with a self-assessment experience that is meaningful and accurate using carefully designed assessment techniques and technology, and that can serve as a viable alternative to the traditional paper and pencil assessment tools that require very little personal involvement in defining and producing the principal's professional growth plan.     

PARENT‐TEACHER COMMUNICATION ABOUT CHILDREN WITH AUTISM SPECTRUM DISORDER: AN EXAMINATION OF COLLABORATIVE PROBLEM‐SOLVING

Effective parent‐teacher communication involves problem‐solving concerns about students. Few studies have examined problem‐solving interactions between parents and teachers of children with autism spectrum disorder (ASD), with a particular focus on identifying communication barriers and strategies for improving them. This study examined the problem‐solving behaviors of parents and teachers of children with ASD. Participants were 18 teachers and 39 parents of children with ASD. Parent‐teacher dyads were prompted to discuss and provide a solution for a problem that a student experienced at home and at school. Parents and teachers also reported on their problem‐solving behaviors. Results showed that parents and teachers displayed limited use of the core elements of problem‐solving. Teachers displayed more problem‐solving behaviors than parents. Both groups reported engaging in more problem‐solving behaviors than they were observed to display during their discussions. Our findings suggest that teacher and parent training programs should include collaborative approaches to problem‐solving.     

Defensive Behaviors in Infant Rhesus Monkeys: Ontogeny and Context-dependent Selective Expression

We examined the ontogeny of the infant rhesus monkey's defensive behaviors and the ability to modulate them in response to specific environmental cues. Rhesus infants in 4 age groups (N = 8 per group) were briefly separated from their mothers and tested under 3 conditions: alone, in the presence of a human who averted his gaze, and in the presence of a human staring at them. Infants as young as 0 to 2 weeks displayed defensive behaviors but did not selectively respond to the human's presence or direction of gaze. By 9 to 12 weeks of age, infants modulated their responses in relation to the parameters of the threat. At this age, infant rhesus monkeys undergo cognitive and emotional changes associated with brain development similar to those in human infants 7 to 12 months old. This also is the time when human infants engage in complex emotional and behavioral responses to threatening situations. Understanding the development and expression of defensive behaviors in infant monkeys should be applicable to similar issues in emotional development of human infants.     

Doctoral dissertations in instructional design and technology, 1977 through 1988

This is a summary of data on doctoral dissertations completed in instructional design and technology programs over the period 1977–88. During this period, 1,518 dissertations were completed at 46 different institutions, with nearly half completed at only 7 institutions. The 1,518 dissertations were chaired by 286 different professors, but approximately half were chaired by just 39 professors. The number per professor ranged from 89 to 1. Output was fairly steady over the 12 years, averaging 127 per year, with a low of 106 in 1980 and a high of 149 in 1983 and 1985.     

Telling physical education teacher education tales through pedagogical case studies

This paper analyses two pedagogical case studies (PCS) from a multidisciplinary perspective to highlight the problems of theoretical knowledge in tertiary physical education teacher education (PETE) programmes, school-based physical education (PE) practice and continuous professional learning (CPL) in PE. We argue that a critical view of tertiary PETE and PE teacher educator CPL practice or practices is particularly important if PETE programmes want to develop future PE and current teacher practitioners who are transformative agents. In setting up the pedagogical case study accounts, we recall common conversations about the bodies of knowledge in tertiary PETE programmes that have been positioned as problematic. The accounts highlight the existence of an artificial divide between PE educators as theory generators and both pre-service PE teachers and school-based PE practitioners as theory appliers. We suggest that part of the reason why this divide exists can be attributed to a general misunderstanding of theoretical and practical knowledge that have been wrongly compartmentalised into ‘theory’ and ‘practice’, and hence erroneously taught as isolated entities without any connection or direct link with each other, or the former considered to be less relevant and perhaps even irrelevant in practice.     

Weeding without Walking: A Mediated Approach to List-Based Deselection

Weeding an academic library is a complicated practice that tends to arouse debate. Despite these contentions, weeding is necessary to deal with the changing needs for space in many libraries. This article describes a holistic weeding project at LaGuardia Community College Library. It reviews several approaches the project team considered and draws on research, practice, and discussion to evaluate them. It concludes that weeding requires a balance between objective rules and professional judgment. The resulting workflow uses an interactive spreadsheet to automate some of the research work involved in deciding the fate of a book, allowing librarians to practice subjective weeding without walking through the stacks.
